A cross-sectional study of the association between Heberden's nodes, radiographic osteoarthritis of the hands, grip strength, disability and pain

OBJECTIVE: To describe the associations between hand osteoarthritis (OA), pain and disability in males and females and to further validate the Australian/Canadian OA hand index (AUSCAN LK3.0). DESIGN: Cross-sectional study of 522 subjects from 101 Tasmanian families (males N=174, females N=348). Hand OA was assessed by two observers using the Altman atlas for joint space narrowing and osteophytes at distal interphalangeal and first carpometacarpal joints as well as a score for Heberden's nodes based on hand photography. Hand pain and function were assessed by the AUSCAN LK3.0 and grip strength by dynamometry in both hands on two occasions. RESULTS: The prevalence of hand OA was high in this sample at 44-71% (depending on site). Pain and dysfunction increased with age while grip strength decreased (all P< 0.001). All three measures were markedly worse in women, even after taking the severity of arthritis into account. Hand OA explained 5.7-10% of the variation in function, grip strength and pain scores, even after adjustment for age and sex. Further adjustment suggested that the osteoarthritic associations with function and grip strength were largely mediated by pain. Severity of disease was more strongly associated with these scores than presence or absence. Lastly, the AUSCAN LK3.0 showed a comparable association to grip strength with structural damage providing further evidence of index validity. CONCLUSIONS: Hand OA at these two sites makes substantial contributions to hand function, strength and pain. The associations with function and strength measures appear mediated by pain. Gender differences in all three measures persist after adjustment for variation in age and OA severity indicating that factors apart from radiographic disease are responsible.     

The short-term effectiveness of low-level laser,phonophoresis, and iontophoresis in patients with lateral epicondylosis

Study DesignRandomized parallel group trial.IntroductionVarious treatment options for lateral epicondylosis have been reported in the literature.Purpose of StudyWe aimed to compare the effectiveness of low-level laser therapy (LLLT), phonophoresis, and iontophoresis in terms of pain, function, and grip strength.MethodsThis study that comprised 37 patients with lateral epicondylosis was planned as a prospective randomized parallel group trial. Twelve participants were randomized to the LLLT group, 12 to the phonophoresis group, and 13 to the iontophoresis group. The Visual Analog Scale (VAS), pressure algometer, the Patient-Rated Tennis Elbow Evaluation, and grip strength dynamometer were used to measure outcomes. The measurements were performed at baseline and at the end of 15 sessions.ResultsInvestigation of the pain scores revealed that all VAS scores were improved in both the laser and iontophoresis groups (VAS at rest: P = .015, effect size (ES) = 1.49 and P = .016, ES = 0.58, respectively; VAS during activity: P = .008, ES = 1.05 and P = .008, ES = 1.16, respectively; VAS at night: P = .013, ES = 1.01 and P = .016, ES = 0.72, respectively). Only advance in function and grip strength was associated with the iontophoresis group (Patient-Rated Tennis Elbow Evaluation P = .006, ES = 0.78; grip strength with elbow extension P = .011, ES = 1.03; with elbow flexion P = .003, ES = 0.52).DiscussionThe most effective approach could not be highlighted among the existing studies in the literature as they were applied in combination with other therapies.ConclusionIn our study, we observed that LLLT provides a benefit only for pain, whereas iontophoresis is beneficial for both pain and function. If the effect size is evaluated, LLLT is more influential than iontophoresis for decreasing pain. However, when we compared phonophoresis and iontophoresis in terms of effectiveness, we found that iontophoresis has better effects for pain, function, and grip strength.     

Preoperative Factors and Patient-Reported Outcomes After Total Hip Arthroplasty: Multivariable Prediction Modeling

BackgroundAlthough total hip arthroplasty (THA) has been established as a cost-effective intervention, some patients experience ongoing pain and dissatisfaction. There is interest in predicting postoperative outcomes based on preoperative data, but the relative contribution of different preoperative factors is unclear. The study’s aim was to develop multivariable prediction models for the assessment of patient-reported outcomes.MethodRegistry data on 1412 patients undergoing THA for osteoarthritis at two hospitals between 2013 and 2018 was used. Potential predictors included age, sex, body mass index, spoken language, education level, previous THA, American Society of Anaesthesiologists (ASA) score, lower back pain, depression/anxiety, other lower limb arthritis, number of other comorbidities, the preoperative expectation of pain and function, EuroQol Visual Analogue Scale (EQ-VAS) and preoperative OHS. Radiographic scores were also used: joint space narrowing (JSN), osteophytes, sclerosis, and an overall grade based on the Kellgren-Lawrence (KL) classification. Outcomes assessed were the patient-rated improvement, satisfaction, and OHS at six months.ResultsJSN or overall KL scores were the most important predictors (P < .001) for all outcomes, with better radiographic scores associated with worse outcomes. Other predictors associated with poorer outcomes were lower back pain and lower expectation (predicting poor improvement), lower education and higher ASA (predicting lower satisfaction) and younger age, female sex, non-English speakers, lower preoperative EQ-VAS, lower education, back pain, and anxiety/depression (predicting lower OHS).ConclusionPreoperative radiological scores are an important predictor of patient-reported outcomes at six months postoperatively. Understanding the relative strengths and significance of different factors in predicting outcomes will help the clinician and patient decision-making for THA.     

The Outcomes of Nonoperative Management of Patients With Hip and Knee Osteoarthritis Triaged to a Physiotherapy-Led Clinic at Minimum 5-Year Follow-Up and Factors Associated With Progression to Surgery

BackgroundThe purpose of this study is to determine outcomes of a nonoperative treatment service for hip and knee osteoarthritis (OA), the “Joint Clinic,” at minimum 5-year follow-up, and investigate factors that may influence progression to joint replacement surgery.MethodsThis is an observational cohort study of 337 patients with hip (n = 151, 45%) or knee OA (n = 186, 55%) seen at the Joint Clinic, at 5-7 years of follow-up. Kaplan-Meier survival curves were used to determine survivorship of the affected joint and Cox regression used to determine factors associated with time to surgery.ResultsAt mean 6-year follow up, 188 (56%) patients had undergone or were awaiting total joint arthroplasty, 127 (38%) were still being managed nonoperatively, and 22 (7%) had died without having surgery. Patients with hip OA were more likely to have required surgery (111/151, 74%) than patients with knee OA (77/186, 41%) (chi-square = 33.6, P < .001). The 7-year surgery-free survival for hip OA was 23.7% and knee OA 55.9% (P < .001). Factors associated with increased likelihood of surgery were joint affected (hip, hazard ratio [HR] 2.80), Kellgren-Lawrence (KL) grade (KL 3, HR 2.02; KL 4, 4.79), and Oxford Hip/Knee Score (HR 1.34 for each 5 points worse at baseline).ConclusionMore than 50% of the patients referred to secondary care with mild-moderate knee OA may not need surgery at 7 years. Patients with hip OA and those with severe radiographic changes are more likely to require surgery and should not be delayed if there is not an adequate response to conservative measures.     

Evaluation of short-term and residual effects of Kinesio taping in chronic lateral epicondylitis: A randomized,double-blinded,controlled trial

BackgroundLateral epicondylitis is degenerative tendinosis of the extensor carpi radialis brevis muscle and is the most common work/sports-related chronic musculoskeletal problem affecting the elbow.PurposeThis study aimed to evaluate the short term and residual effectiveness of the Kinesio taping method on pain, grip force, quality of life, and functionality.Study DesignRandomized, double-blinded, controlled study.MethodsSubjects were 50 patients diagnosed with chronic unilateral lateral epicondylitis with a symptom duration of at least 12 weeks. During the first four weeks, the study group received a true inhibitor Kinesio taping while the control group received sham taping. In both groups, progressive stretching and strengthening exercises were given as a home program for six weeks. The primary outcome measure was the Numerical Rating Scale (NRS) for self-report of pain intensity; secondary outcome measures were Cyriax resistive muscle test evaluation, maximal grip strength, Patient- Rated Tennis Elbow Evaluation (PRTEE), and Short Form-36 (SF-36). After the treatment, patients were evaluated by the first assessor who was blinded to taping types.ResultsThere was a significant decrease in NRS scores overtime during the first four weeks in both groups (P < .001,) and effect sizes were large. There was no significant difference in Cyriax muscle resistance test maximal grip strength between groups (P > .05). However, there was a significant improvement in muscle strength of elbow extension and pronation in the study group detected in the intragroup analysis. Intragroup comparisons also showed a significant improvement in all subunits of the PRTEE and SF-36 except energy/vitality, social functioning, and pain in both groups (P < .05) with moderate to high effect sizes. PRTEE pain scores were significantly decreased in the study group compared to the placebo group (P < .05, d = 0.48).ConclusionThe effects of Kinesio taping on muscle strength, quality of life, and function in chronic lateral epicondylitis are not superior to placebo. However, NRS scores showed that in the two weeks after Kinesio taping treatment, pain reduction persisted as a residual effect which may improve the exercise adherence and functionality.     

The effects of strength training among persons with hand osteoarthritis: a two-year follow-up study.

Hand exercise is recommended for hand osteoarthritis (OA) management, but few efficacy studies have been published. The purpose of the study was to determine the effects of two years of whole body strength training and gripper exercise on hand strength, pain, and function in adults with radiographic evidence of hand OA. Older adults (N=55; 71.5+/-6.5 years; 80% female) participated in a two-year, three times per week strength training regimen. Bilateral gripper exercise weight (i.e., isotonic grip strength), isometric grip strength, pain, and self-reported hand, and finger function were recorded at baseline and 24 months. Isotonic grip strength increased 1.94 kg (20.14 kg baseline, 22.09 kg follow-up; p<0.0003). Right and left isometric grip increased 3.62 kg (25.83 kg baseline, 29.45 kg follow-up; p<0.002) and 2.95 kg (22.73 kg baseline, 25.65 kg follow-up; p<0.0005), respectively. Hand pain decreased from 4.77 to 2.62 (p<0.006). Hand and finger function scores showed minimal dysfunction at baseline and follow-up. Results suggest strength training safely increases dynamic and static grip strength and reduces pain in older persons with hand OA.     

The Influence of Radiological Severity and Symptom Duration of Osteoarthritis on Postoperative Outcome After Total Hip Arthroplasty: A Prospective Cohort Study

Background

We aimed to investigate the influence of preoperative radiological severity and symptom duration of hip osteoarthritis (OA) on the postoperative functional outcome, quality of life, as well as abductor muscle strength after total hip arthroplasty (THA).

Arthroscopic ligamentoplasty for osteoarthritis of the thumb carpometacarpal joints: Clinical and radiological outcomes with a minimum 2-year follow-up

BackgroundWe reported a new technique for arthroscopic ligamentoplasty for the thumb carpometacarpal osteoarthritis (CMC-OA) along with a minimum of 2 years of results.MethodsTwenty-nine thumbs with CMC-OA in stages II and III according to the Eaton and Glickel classification, were treated by arthroscopic ligamentoplasty. The procedure included partial trapeziectomy followed by ligamentoplasty similar to the Thompson technique. We evaluated pain VAS; DASH; grip and pinch strength; thumb abduction range of motion, and radiographic examination preoperatively and every 3 months until 1 year after surgery, and every 6 months thereafter. The mean duration of the follow-up was 3.2 years with a range of 2.0–6.0 years.ResultsPain, VAS, and DASH were significantly improved at 3 months after surgery than those preoperatively. Further, the strength of grip, tip, and key pinch significantly increased at 9, 9, and 12 months after surgery, respectively. Additionally, these improvements were maintained until the final follow-up. The range of motion tended to decrease in both palmar and radial abduction, although the differences were not significant. Radiographic examination after surgery showed that the ratio of trapezial space was significantly reduced because of surgical excision of the trapezium. However, there were no significant differences in the results between each follow-up time and the final follow-up. Moreover, the ratio of subluxation on the plain X-ray was significantly improved and maintained until the final follow-up. The parameters of clinical and radiographic outcomes, except motion, were significantly improved, even in patients with including those in stage III and with greater than 1/3 subluxation of the 1st metacarpal base on plain radiography.ConclusionArthroscopic ligamentoplasty was effective for pain relief and improvement of grip and pinch strength for the patients with symptomatic CMC-OA.Level of evidenceTherapeutic study/Level IV.     

More Severe Radiographic Osteoarthritis Is Associated With Increased Improvement in Patients’ Health State Following a Total Knee Arthroplasty

BackgroundTo assess whether preoperative radiological severity of osteoarthritis (OA) is related to the level of improvement in patients’ health state measured 1 year after total knee arthroplasty (TKA).MethodsRadiographic severity of OA was graded using the Kellgren-Lawrence (KL) classification. Two independent observers were blinded to patients’ outcome scores. Health-related quality of life was measured using EQ-5D-3L preoperatively and at 12-month follow-up. The 5 dimensions of the EQ-5D were converted into a health state index score. The association between KL grade and improvement in health state score was analyzed using multiple linear regression.ResultsAmong 156 consecutive patients (68% females, mean age 69 years) who underwent primary TKA, 3 knees (2%) were classified as KL grade 2, 115 as KL grade 3 (74%), and 38 as KL grade 4 (24%). Follow-up rate was 77%. There was substantial intra-rater and inter-rater agreement (Cohen’s kappa = 0.80 and 0.79). Most patients (64%) had clinically significant improvement in their health state score 1 year after TKA. However, after adjusting for relevant covariates, patients with severe OA (KL grade 4) were found to have significantly more improvement in their health state score than patients with mild or moderate OA (KL grade 2 or 3, respectively). Separate analysis of the 5 EQ-5D dimensions showed that the KL group differences were most evident in the “usual activities” and “pain/discomfort” dimensions.ConclusionPatients with severe OA have significantly more improvement in their usual activities and pain/discomfort 1 year after TKA than patients with less severe OA.     

Carpometacarpal and metacarpophalangeal joint collapse is associated with increased pain but not functional impairment in persons with thumb carpometacarpal osteoarthritis

IntroductionDue to the complex shape of the carpometacarpal (CMC) joint, a fixed joint collapse deformity of the thumb CMC (CMC1) and metacarpophalangeal (MCP1) joint can present in advanced stages of CMC1 osteoarthritis (OA), resulting in adduction of the first metacarpal (MC1) and hyperextension of the MCP1.Purpose of the StudyTo determine whether joint collapse deformity is associated with worse pain and/or functional impairment.Study DesignCross-sectional.MethodsThis study used the baseline data from 140 patients enrolled in a longitudinal study of treatment for CMC1 OA. (efficacy of combined conservative therapies on clinical outcomes in patients with CMC1 OA). Joint collapse was determined at baseline using a pinch gauge. Pain was assessed on a visual analog scale (0-100) and function was assessed using the Functional Index for Hand Osteoarthritis questionnaire (0-30). Pain and function and the presence of joint collapse were entered in a univariate logistic regression. The final adjusted model for pain and joint collapse included age and sex. The final adjusted model for function and joint collapse included Kellgren Lawrence grade and grip strength.ResultsAbout 20% of participants demonstrated joint collapse on the tip-pinch test. The presence of joint collapse was associated with increased pain in the unadjusted [P = .047, OR = 2.45, 95% CI (1.01, 5.910)] and adjusted model [P = .049, OR = 2.45, 95% CI (1.00, 5.98)].ConclusionCMC1 patients with joint collapse reported increased pain compared with those without joint collapse. Future studies should determine the relationship between thumb hypermobility and joint collapse and how to manage these conditions effectively.     

Dynamic stabilization home exercise program for treatment of thumb carpometacarpal osteoarthritis: A prospective randomized control trial

Study DesignRandomized control trial.IntroductionThumb carpometacarpal (CMC) osteoarthritis (OA) is a common cause of hand pain and disability. Standard conservative therapy (SCT) for thumb CMC OA includes an orthosis and instruction in joint protection, adaptive equipment, and pain relieving modalities. The dynamic stability home exercise (HE) program is complementary conservative therapy designed to strengthen the stabilizing muscles of the thumb CMC.Purpose of the StudyTo investigate whether the addition of HE to SCT (SCT+HE) was more effective at reducing pain and disability in thumb CMC OA compared to SCT alone.MethodsThe study compared 2 groups: SCT and SCT+HE. The SCT group received SCT with in-home pain management instructions, joint protection strategies with adaptive equipment, and a hand-based thumb-spica orthosis. The SCT+HE group received HE program instructions for adductor stretching and opponens and first dorsal interosseous strengthening in addition to SCT. Our primary outcome measure was the numerical rating scale (NRS) with secondary outcome measures of QuickDASH (shortened Disabilities of the Arm, Shoulder and Hand questionnaire), range of motion, grip strength, and pinch strength. Outcome measurements were assessed at first visit, 6 weeks, and 6 months.ResultsThere was no statistical difference between the 2 groups for NRS and QuickDASH at 6 weeks (P = .28 and P = .36, respectively) or 6 months (P = .52 and P = .97, respectively). However, there was a statistically significant decrease in NRS and QuickDASH scores at 6 weeks and 6 months within both groups.ConclusionsBoth SCT and SCT+HE are effective at reducing pain and disability in OA of the thumb CMC joint. Neither therapy program was superior to the other at improving NRS or QuickDASH scores at 6-week or 6-month follow-up.     

Evolution of an Opioid Sparse Pain Management Program for Total Knee Arthroplasty With the Addition of Intravenous Acetaminophen

BackgroundPerioperative pain management for patients undergoing total knee arthroplasty (TKA) improves patient outcomes and facilitates recovery. In this study, we compared the effects of preoperative oral acetaminophen vs intravenous (IV) acetaminophen administered once intraoperatively and once postoperatively.MethodsTwo standardized, multimodal analgesia protocols were compared in patients undergoing primary, unilateral TKA. The oral acetaminophen cohort (OA) received doses of oral acetaminophen preoperatively and an as-needed basis postoperatively (n = 698). The IV acetaminophen cohort (IA) received 2 doses of IV acetaminophen, one intraoperative and one 6 hours postoperatively, with no oral acetaminophen given (n = 318). No other variables were significantly changed during the study period.ResultsThe IV acetaminophen group demonstrated less narcotic usage on postoperative day 0 (OA: 13.3 mme [morphine mg equivalents], IA: 6.2 mme, P < .001) and overall usage (OA: 66.1 mme, IA: 48.5 mme, P < .001). Pain scores were statistically and clinically significantly decreased in the immediate postoperative (the first 8 hours) for the IA group (OA: patient-reported pain scores of 4.0; IA: patient-reported pain scores of 2.0, P < .001). Both groups progressed and completed their physical therapy similarly for each postoperative day. Length of stay and percent discharge home were slightly improved in the IA group as well, however did not reach statistical difference.ConclusionAn iterative approach to multimodal pain management after TKA led to improvements in narcotic usage, pain scores, and several quality measures. IV acetaminophen is an integral and effective part of our opioid-sparing multimodal pain regimen in TKA.     

Role of Triple Injection Platelet-Rich Plasma for Osteoarthritis Knees: A 2 Years Follow-Up Study

PurposeTo assess the clinical outcomes of intra-articular Platelet-rich plasma (PRP) injection in knee osteoarthritis (OA) at 2 year follow-up.MethodsThis was a prospective interventional study. 68 cases (105 knees) with Kellgren-Lawrence (KL) grades I, II and III knee OA received 3 intra-articular injections of PRP 1 month apart. The cases were followed up for 2-years. Outcomes were measured using Western Ontario and McMaster Universities Arthritis Index (WOMAC) score and Visual analog scale (VAS) scores.ResultsThe mean age was 51.7 years. 18 knees had KL grade I, 55 had grade II and 32 had grade III OA. The mean pre-treatment VAS score decreased significantly at 1 year (mean difference − 5.3, p = 0.003) and 2 year follow-up (mean difference − 6, p = 0.007). The mean pre-treatment WOMAC score decreased significantly at 1 year (mean difference − 45.9, p = 0.011) and at 2 year (mean difference − 52.4, p = 0.009). The WOMAC and VAS scores improved significantly from baseline to final follow-up across all KL grades (p = 0.001 and 0.001, 0.009 and 0.007, 0.021 and 0.017 for WOMAC and VAS across KL grade I, II and III, respectively). There was no significant differences in WOMAC and VAS scores between three KL grades at final follow-up (p = 0.17 and 0.09, respectively), although the baseline scores had significant difference (p = 0.001 for both VAS and WOMAC) with worse scores in higher KL grades. The variables like age, sex, BMI, KL grade, baseline VAS and baseline WOMAC did not predict the final VAS and WOMAC scores.ConclusionTriple injection of intra-articular PRP given one month apart significantly relieves the symptoms of knee OA till 2 years in KL grade I, II and III. The improvement in symptoms at 2-year follow-up did not differ across different KL grades.     

Reliability of handgrip strength test in elderly subjects with unilateral thumb carpometacarpal osteoarthritis

BackgroundThe grip strength test is widely used; however, little has been investigated about its reliability when used in elderly with subjects thumb carpometacarpal (CMC) osteoarthritis (OA). The purpose of this study was to examine the test–retest reliability of the grip strength test in elderly subjects with thumb CMC OA.MethodsA total of 78 patients with unilateral thumb CMC OA, 84.6 % female (mean ± SD age 83 ± 5 years), were recruited. Each patient performed three pain free maximal isometric contractions on each hand in two occasions, 1 week apart. Intraclass correlation coefficient (ICC), standard error of measurement (SEM), and 95 % limits of agreement (LOA) were calculated.ResultsTest–retest reliability was excellent for side affected (ICC = 0.947; p = 0.001) and contralateral (ICC = 0.96; p = 0.001) thumb CMC OA.ConclusionsThe present results indicate that maximum handgrip strength can be measured reliably, using the Jamar hand dynamometer, in patients with thumb CMC OA, which enables its use in research and in the clinic to determine the effect of interventions on improving grip.     

Do Knee Osteoarthritis Patterns Affect Patient-Reported Outcomes in Total Knee Arthroplasty? Results From an International Multicenter Prospective Study With 3-Year Follow-Up

BackgroundThe aim of this multicenter study is to answer (1) Does patellofemoral osteoarthritis (OA) affect preoperative Knee Injury and Osteoarthritis Outcome Score (KOOS) scores in total knee arthroplasty (TKA)? and (2) Do different OA patterns affect preoperative and postoperative KOOS scores in TKA?MethodsThis international, multicenter prospective study examined 384 TKA patients. Compartmental OA was divided into (1) medial, (2) medial + patellofemoral, (3) lateral, (4) lateral + patellofemoral, (5) medial + lateral (bicompartmental), and (6) medial + lateral + patellofemoral (tricompartmental), based on preoperative anterior-posterior and lateral ± skyline radiographs with Kellgren-Lawrence grade III-IV and joint space width <2.5 mm. KOOS was collected preoperatively, 1 year postoperatively, and 3 years postoperatively. Higher KOOS score represented better clinical state, for example, higher KOOS Pain score indicated less pain.ResultsPatellofemoral OA had no effect on preoperative KOOS scores (P > .15). Compared to medial ± patellofemoral OA patients, bicompartmental/tricompartmental OA patients had less preoperative pain (KOOS Pain 7.4, P = .03) and higher daily function (KOOS-ADL [Activities of Daily Living] 7.1, P = .05), and higher 1-year postoperative daily function (KOOS-ADL 9.2, P = .03) and sports activity (KOOS Sports & Recreation Function 15.0, P = .04), while lateral ± patellofemoral OA patients had more symptoms (KOOS-Symptoms 7.0, P < .01), more pain (KOOS-Pain 7.5, P = .01), lower daily function (KOOS-ADL 9.3, P < .01), and lower quality of life (KOOS-QOL 9.0, P = .04), at 3 years postoperatively.ConclusionPatellofemoral OA does not affect medial ± lateral OA patients’ preoperative KOOS scores, challenging the importance of patellofemoral OA in TKA. Lateral ± patellofemoral OA patients have lower postoperative KOOS scores than medial/more progressed compartmental OA patients, indicating that patients with less common OA patterns present with unique surgical challenges. Further development of indications for and correct timing of TKA surgery in different patient subgroups is needed.     

The functional outcome of acute scapholunate ligament repair in patients with intraarticular distal radius fractures treated by internal fixation

Background

Intra-articular fractures of the distal radius (DRF) are associated with a twofold increase in the risk of scapholunate ligament injury (SLI). The aim of this study was to compare functional outcome, pain, and disability between patients with operatively treated DRF and either an acute, repaired scapholunate ligament injury or no ligament injury.

Methods

We retrospectively analyzed 18 patients with an intraarticular DRF and SLI that was diagnosed and treated (Group I) and compared them with 20 patients with DRF without associated ligament injury (Group II) (20 women, 18 men; average age 55 years, range 19–72). The two cohorts were analyzed for differences in motion, grip strength, pain, Mayo wrist score, and Quick Disabilities of the Arm, Shoulder, and Hand (DASH) score an average of 43 months (range 12–73) after surgery. Radiographic assessment included fracture union, palmar tilt, radial inclination, ulnar variance, intercarpal angles, and arthrosis (according to Knirk and Jupiter). We used T-tests to compare range of motion, grip strength, pain (visual analog scale), DASH scores, and radiographic alignment between cohorts. A Chi-squared analysis was used to determine radiographic differences of arthritis.

Results

There were no significant differences in mean range of motion, grip strength, Quick DASH score, Mayo wrist score, pain level, or radiographic arthrosis between cohorts. There was no correlation between radiographic signs of osteoarthritis and the QuickDASH score, and pain level.

Conclusion

The outcomes of intraarticular fractures of the distal radius with operatively treated associated SLI are comparable with the outcomes of intraarticular fractures of the distal radius without associated SLI.     

Investigating the effects of neuromobilization in lateral epicondylitis

Study DesignRandomized controlled study.IntroductionLateral epicondylitis (LE) causes pain and loss of function in the affected limb. Different exercises have been used for the treatment of LE. In recent years, the technique of neuromobilization has been frequently used to treat tendinopathy. However, there is no study that demonstrates the effects of neuromobilization techniques on patients with LE.Purpose of the StudyThe aim of the present study was to determine the effects of neuromobilization techniques on pain, grip strength, and functional status in LE patients and to compare them with conservative rehabilitation treatment.MethodsA total of 40 patients (26 females and 14 males; age: 42.80 ± 8.91 years) with a history of LE participated in the study. The patients were randomly assigned to two groups: the neuromobilization group and the control group. The neuromobilization group completed a 6-week conservative rehabilitation and radial nerve mobilization program, whereas the control group received conservative rehabilitation therapy only. Both groups underwent a 7-day weekly conservative home rehabilitation program. Pain severity, grip strength, pinch strength, joint motions, and upper extremity functional level were assessed before treatment, at the third week after treatment, and at the sixth week after treatment.ResultsThere was a significant decrease in all pain scores in favor of the neuromobilization group at week 6 after treatment (at rest: P = .001, effect size (ES) = 0.84; at night: P = .001, ES = 0.91 and during activity: P = .004, ES = 1.06). No significant differences were found for grip strength, pinch strength, joint motions, and functional level in the neuromobilization group, although trends toward better improvement were observed.ConclusionsRadial nerve mobilization techniques are more effective on pain than conservative rehabilitation therapy in LE patients, and this effect continues after treatment.     

The Impact of Race and Socioeconomic Status on Total Joint Arthroplasty Care

BackgroundRacial minorities and patients from lower socioeconomic backgrounds are less likely to undergo total joint arthroplasty (TJA) for degenerative joint disease (DJD). However, when these patients do present for care, little is known about the overall severity of DJD and surgical wait times.MethodsA retrospective cohort of 407 patients (131 black and 276 white) who presented to an arthroplasty clinic and went on to receive TJA was established. Severity of osteoarthritis was assessed radiographically via Kellgren-Lawrence (KL) grade. Preoperative Knee Society Score (KSS) and Harris Hip Score (HHS) were used to measure joint pain and function. Multivariate regression modeling and analysis of covariance were used to examine racial and socioeconomic differences in KL grade, KSS, HHS, and time to surgery.ResultsBlack patients presented with significantly greater KL scores than white patients (P = .046, odds ratio = 1.65, 95% confidence interval [1.01, 2.70]). In contrast, there were no statistically significant racial differences in the mean preoperative KSS (P = .61) or HHS (P = .69). Black patients were also found to wait, on average, 35% longer for TJA (P = .03, hazard ratio = 1.35, 95% confidence interval [1.04, 1.75]). Low income was associated with higher KL grade (P = .002), lower KSS (P = .07), and lower HHS (P = .001).ConclusionDespite presenting with more advanced osteoarthritis, black patients reported similar levels of joint dysfunction and had longer surgical wait times when compared with white patients. Lower socioeconomic status was similarly associated with more severe DJD.     

Self-efficacy corresponds to wrist function after combined plating of distal radius fractures

Study DesignA prospective cohort single-center study.IntroductionSelf-efficacy (SE) refers to beliefs in ones capabilities to organize and execute the courses of action required to produce given goals. High SE is an important factor for recovery from injury/illness; people who believe in their capability will more likely reach a good outcome.Purpose of the StudyThe aim of this study was to examine if SE has an effect to physical functioning, pain and patient-rated wrist function three months postoperatively in patients undergoing plating due to a distal radius fracture.MethodsSixty-seven patients undergoing plating for a distal radius fracture rated SE at the first appointment with the physiotherapist. At the three-month follow-up, the following assessments were administered: Patient-Rated Wrist Evaluation (PRWE), pain-scores, hand grip strength, and range of motion.ResultsThe group with a high SE showed significantly better range of motion for flexion (P = .046) and supination (P = .045), hand grip strength (P = .001) and PRWE scores (P = .04). The NRS pain during activity was lower, although not significantly lower (P = .09). Using Spearman's rank correlation coefficient, there was a moderate correlation between SE and pain during activity, wrist flexion, and PRWE score.DiscussionSE corresponds to wrist function after combined plating of distal radius fractures.ConclusionMeasurement of SE could possibly be useful to identify patients in special need of support during the postoperative rehabilitation.
