Risk factors for achilles tendon rupture: A matched case control study

PurposeThe purpose of this study was to elucidate whether body mass index (BMI), activity level, and other risk factors predispose patients to Achilles tendon ruptures.Materials and methodsA retrospective review of 279 subjects was performed (93 with Achilles tendon rupture, matched 1:2 with 186 age/sex matched controls with ankle sprains). Demographic variables and risk factors for rupture were tabulated and compared.ResultsThe rupture group mean BMI was 27.77 (95% CI, 26.94–28.49), and the control group mean BMI was 26.66 (95% CI, 26.06–27.27). These populations were found to be statistically equivalent (p = 0.047 and p < 0.001 by two one-sided t-test). A significantly higher proportion of those suffering ruptures reported regular athletic activity at baseline (74%) versus controls (59%, p = 0.013).ConclusionThere was no clinically significant difference found in BMI between patients with ruptures and controls. Furthermore, it was found that patients who sustained ruptures were also more likely to be active at baseline than their ankle sprain counterparts.     

Early rehabilitation after open repair for patients with a rupture of the Achilles tendon

PurposeAs outdoor activities participation increase, Achilles tendon rupture incidence also tends to increase. There are a number of treatment and rehabilitation options for a ruptured Achilles tendon. However, the optimal rehabilitation protocols are still under debate. The purpose of this study is to determine whether early rehabilitation is more effective than conventional rehabilitation.MethodsMedical records of 56 patients who had been treated with open repair after a ruptured Achilles tendon were retrospectively reviewed. 24 patients were treated postoperatively with below knee cast immobilization for four weeks, and they started tolerable weight-bearing rehabilitation at four weeks’ follow-up. The remaining 32 patients were managed postoperatively with short leg splint immobilization for two weeks and started the tolerable weight-bearing at two weeks’ follow-up. We evaluated the patients several times to identify when the single heel raise was possible and measured the American Orthopedic Foot and Ankle Society (AOFAS) scores and Achilles tendon total rupture scores (ATRS) as a functional outcome.ResultsThe single heel raise test was positive in all patients at the last assessment. But there were no statistically significant differences between the groups (p = 0.137). The patients in the Cast group took significantly more time to return to work than did the patients in the Splint group (p = 0.032). And AOFAS scores and ATRS were slightly higher in the Splint group than in the Cast group. There were statistically significant differences (p = 0.042, p = 0.028) between the two groups.ConclusionThe early rehabilitation did not lead to greater endurance, but it showed better results in the return to work and the Achilles functional score. Early rehabilitation after open repair for patients with a ruptured Achilles tendon is helpful for functional recovery.Type of study / Level of evidence: Therapeutic, Level III.     

The influence of an orthopaedic walker boot on forefoot force

BackgroundIn the treatment of an Achilles tendon rupture the patients are commonly equipped with an orthopaedic walker boot with wedges. To what extent this influences the tensile force placed on the Achilles tendon is unclear.PurposeTo assess the forefoot force and describe changes in muscle activity of the medial gastrocnemius, soleus and tibialis anterior when using one or three wedges during ambulation in a weightbearing orthopaedic walker boot.MethodsThe force on the forefoot was measured with a force sensor insole and muscle activity of the medial gastrocnemius, soleus and tibialis anterior were measured using surface electromyography in 10 healthy participants. Three different types of ambulation were performed (walking without crutches (unass.), walking with crutches (+crutch) and walking with crutches and verbal instructions to place body weight on heel (heel + crutch) with one and three heel wedges respectively.FindingsThe total peak force displayed an interaction where forefoot force decreased when wearing three wedges only for the +crutch ambulation type (80 N, p = 0.001) although there was a trend to decrease with three wedges also for the heel + crutch ambulation type (48 N, p = 0.05). The relative peak force on the forefoot showed a main effect with a significant decrease when using three wedges compared to one wedge across all three ambulation types (19.1%, p = 0.009).InterpretationThe force on the forefoot and hereby the Achilles tendon significantly decreased when using three wedges compared to one wedge. These findings have important implications for the rehabilitation post Achilles tendon rupture.     

Achilles tendinoscopy and plantaris tendon release and division in the treatment of non-insertional Achilles tendinopathy

BackgroundThe mainstay of treatment for non-insertional Achilles tendinopathy is non-operative, however a proportion of patients will fail conservative measures. We describe the results of Achilles tendinoscopy with plantaris tendon release in patients who have failed first line conservative treatment for at least 6 months.MethodsA consecutive series of 11 patients with a minimum of 2 years follow up.ResultsThe mean AOFAS scores significantly improved from 68 pre-op to 92 post op (p = 0.0002) as did the AOS scores for both pain (28% pre-op to 8% post op (p = 0.0004)) and disability (38% pre-op to 10% post op (p = 0.0005). The mean SF-36 scores also improved but were not statistically significant (pre-op 76, post op 87 (p = 0.059). There were no complications. 8 of the 11 patients were satisfied, the other 3 somewhat satisfied.ConclusionsThe results of Achilles tendinoscopy and division of the plantaris tendon are encouraging but further studies are required to compare it to other treatments. It is minimally invasive and low risk so should not affect the ability to perform a formal open procedure if unsuccessful.     

Diagnostic performance of isolated orbital CT scan for assessment of globe rupture in acute blunt facial trauma

ObjectivesWe determine the diagnostic performance of emergent orbital computed tomography (CT) scans for assessing globe rupture in patients with blunt facial trauma.MethodsWe performed a retrospective cohort study based on prospectively collected trauma registry and acute care surveillance data in a tertiary-care hospital. Patients aged at least 18 years who underwent isolated orbital CT scanning for assessing potential ocular trauma were examined. Analyses were performed to evaluate the magnitude of agreement between diagnosis by CT scanning and ophthalmic assessment, including globe rupture.ResultsOur study cohort comprised 136 patients, 30% of whom (41 patients) sustained orbital wall fractures. Concordance for orbital CT diagnosis and the ophthalmic assessment of globe rupture was substantial (k = 0.708). The relative risk of globe rupture was 0.692 (95% confidence interval (CI): 0.054–8.849) for superior wall fractures, 0.459 (95% CI: 0.152–1.389) for inferior wall fractures, 2.286 (95% CI: 1.062–4.919) for lateral wall fractures, and 0.637 (95% CI: 0.215–1.886) for medial wall fractures. According to multivariate analysis, lateral wall fractures were an independent risk factor for globe ruptures (adjusted odds ratio (OR) = 12.01, P = 0.011), and medial or inferior wall fracture was a protective factor (adjusted OR = 0.14, P = 0.012). In the stratified analysis of diagnostic performance of CT scan, specificity was highest among patients with orbital wall fractures (97.2%), followed by negative predictive volume (NPV, 97%), and accuracy (95.1%).ConclusionAmong patients with blunt facial trauma who underwent isolated orbital CT scanning as part of ocular trauma assessment, the diagnostic performance of CT in detecting globe rupture is more accurate in patients with orbital wall fractures. Nevertheless, isolated orbital CT alone does not have a sufficiently high diagnostic performance to be reliable to rule out all globe ruptures. Lateral orbital wall fractures in blunt facial trauma patients, in particular, should prompt thorough evaluation by an ophthalmologist.     

Abdominal Aortic Aneurysm Rupture is not Associated with an Up-regulation of Inflammation within the Aneurysm Wall

BackgroundThe nature of the inflammatory change within ruptured AAA has not been extensively reported. The aim of this study was to compare the inflammatory response in non-ruptured and ruptured aneurysms with emphasis on the site of rupture.MethodsNon-rupture site biopsies were taken from the anterior aneurysm sac of non-ruptured (n = 31) and ruptured AAA (n = 20). In 12 ruptured AAA, a further biopsy was taken from the rupture site. Enzyme-linked immunosorbent assay was used to quantify IL-6, IL-1beta and TNF-alpha. Quantitative immunohistochemistry was undertaken for generic lymphocytes, T-cells, and B-cells.ResultsComparing biopsies in non-ruptured AAA versus a non-rupture site biopsy from ruptured AAA; there was no significant difference in IL-6, IL-1β, TNF-alpha, generic lymphocytes, T-cell or B-cell content. Comparing ruptured AAA – non-rupture site with rupture site; IL-6 and TNF-alpha were unchanged. By contrast IL-1β and lymphocytes were lower at the rupture site compared to the non-rupture site (IL-1β 1.39 ng/mg [0.97–2.29] vs. 1.92 ng/mg [1.46–2.57], p = 0.027; generic lymphocytes 2.89% [0.51–5.51] vs. 4.73% [2.27–12.40], p = 0.018; T-cells 0.28% [0.04–1.18] vs. 0.82% [0.40–1.36], p = 0.027; B-cells 0.16% [0.04–1.14] vs. 1.30% [0.32–5.40], p = 0.021).ConclusionsThese findings suggest the biological events leading to AAA rupture may not be dependent on an up-regulation in the inflammatory process.     

Treadmill versus overground gait training in patients with lower limb burn injury: A matched control study

IntroductionGait impairment is commonly seen in patients with a lower limb burn injury (LLBI). Therefore, the aim of this study was to investigate the effects of two different gait training modes on gait symmetry, functional mobility and kinesiophobia in patients with LLBI.MethodsThis matched control study was conducted between January 2017 and August 2018. Patients with LLBI (n = 28) were allocated to 2 different groups by matching according to burn localization, age, and gender. Group 1 (overground group: n = 14) received overground gait training in addition to standard burn rehabilitation, and Group 2 (treadmill group: n = 14) received treadmill gait training in addition to standard burn rehabilitation. The rehabilitation program and gait training were started when the patient was admitted to the hospital and ended on discharge. These physical therapy interventions were performed 5 days per week. The gait training intensity, including walking speed and duration, was determined according to patient tolerance. Gait parameters, functional mobility, kinesiophobia and pain values were evaluated with GAITRite, the timed up-and-go test (TUG), Tampa Kinesiophobia Scale and Visual Analogue Scale, respectively. These evaluations were made twice; on admission and immediately prior to discharge. Gait symmetry was calculated using the Symmetry Index.ResultsThe baseline characteristics of the groups and initial outcome values were similar. In the comparison of the differences between the overground and treadmill groups, the change in kinesiophobia and TUG values were significantly higher in the treadmill group (p = 0.01, p = 0.02, respectively). The intragroup comparisons showed significant differences in SI in respect of step length (p = 0.004), swing (p = 0.006), stance (p = 0.008) and velocity (p = 0.001), cadence (p = 0.001), TUG (p = 0.001), kinesiophobia (p = 0.001) and pain (p = 0.001) in the overground group. Statistically significant differences were determined in step length (p = 0.01), swing (p = 0.01), stance (p = 0.02) and velocity (p = 0.001), cadence (p = 0.001), TUG (p = 0.001), kinesiophobia (p = 0.001) and pain (p = 0.001) in the treadmill group, when pre and post-training values were compared.ConclusionsThe results of this study have shown that treadmill gait training was more effective in the improvement of functional mobility and reduction in kinesiophobia levels of patients with LLBI compared to overground gait training. Both overground and treadmill gait training also provide greater improvements in the velocity and cadence, and gait symmetry for step length, swing and stance in patients with LLBI.Clinical trial registration numberNCT03217526.     

The impact of serum albumin and serum protein levels on POSSUM score of patients with proximal femur fractures

BackgroundPOSSUM was developed to predict risk-adjusted mortality and morbidity rates for surgical procedures. We evaluated the impact of serum albumin and serum protein levels on POSSUM scores.MethodsMedical files of 2269 patients operated for proximal femur fractures were reviewed. Preoperative serum albumin levels were available for 387 patients (mean 35.1 g/l, range 22–49) and serum protein levels for 279 patients (mean 61.6 g/l, range 40–86).ResultsSerum albumin and protein levels were inversely associated with mortality in multivariate models (albumin, OR = 0.89, p = 0.009; protein, OR = 0.92, p = 0.009) and in composite outcome models as well (albumin, OR = 0.955, p = 0.219, protein, OR = 0.94, p = 0.014). The area under the curve (AUC) for POSSUM prediction of mortality (n = 1770) was 0.632 (95% CI: 0.580–0.684, p < 0.001). The AUC for a model including serum protein levels was 0.742 (95% CI: 0.649–0.834, p < 0.001). Hospitalisation time was longer for patients with lower serum proteins levels (p = 0.045), with an inverse correlation (Pearson correlation −0.164, p = 0.011).ConclusionsLower preoperative serum albumin and serum protein levels were associated with increased risk for mortality, increased hospitalisation time and poorer outcomes in patients operated for proximal femoral fractures. Including those values to POSSUM scores would increase their predictive power.     

Oncological outcomes of laparoscopic nephroureterectomy with pluck method for distal ureter resection

ObjectiveTo report the oncologic outcomes of upper tract urothelial carcinoma treated with laparoscopic nephroureterectomy and pluck method for distal ureter resection.Materials and methodsBetween May 2004 and November 2015, 118 patients with upper urinary tract urothelial carcinoma received laparoscopic radical nephroureterectomy with endoscopic bladder cuff excision at our institution. The medical records were reviewed retrospectively for clinical and pathological results. Cox regression analyses were performed on factors related to oncological outcomes.ResultsThe median follow-up was 26 months. Bladder recurrence was found in 27 patients (22.9%), extravesical retroperitoneal recurrence in four patients (3.4%), and metastases in 17 patients (14.4%). Multivariate analyses showed that male sex was associated with higher bladder recurrence [odds ratio (OR) = 2.2; 95% confidence interval (CI), 1.02–4.78; p = 0.045)], tumor size had significant correlation with locoregional recurrence (OR = 1.29; 95% CI, 1.07–3.43; p = 0.029), tumor stage was significantly correlated with subsequent metastasis (OR = 2.08; 95% CI, 1.21–3.56; p = 0.008) and overall survival (OR = 1.84; 95% CI, 1.06–3.22 ; p = 0.031), and tumor size correlated significantly with cancer-specific survival (OR = 2.57; 95% CI, 1.16–5.72; p = 0.021).ConclusionsTumor size and tumor stage were significantly associated with survival (cancer-specific and overall survival) in patients receiving nephroureterectomy with pluck method.     

Clinical and Angiographic Follow-up of Spontaneous Isolated Superior Mesenteric Artery Dissection

ObjectivesTo observe the clinical features and angiographic findings in patients with a spontaneous isolated superior mesenteric artery dissection (SISMAD) and to identify any correlation between them.MethodsFrom a single institution, 32 patients (22 symptomatic patients at presentation; mean age 54 years; men 97%) with SISMAD were retrospectively reviewed. All patients were available for clinical follow-up after treatment (conservative, n = 28, 88%, open or endovascular superior mesenteric artery (SMA) reconstruction, n = 4, 12%), and follow-up CT scans were available in 28 patients (mean 22 months, range 1–80 months).ResultsWe found a positive correlation between pain severity and dissection length (p = 0.03, ρ = 0.50, Spearman's partial correlation analysis). After conservative treatment, only one patient (3%) required bowel resection, and there was no difference in outcome between patients who were treated with anticoagulation or anti-platelet therapy and those who were not (p = 1.00, Fisher's exact test). No patients had progression of their lesion on the follow-up CT angiography.ConclusionsIn SISMAD patients, dissection length is positively associated with more severe clinical symptoms. After conservative treatment, we observed a benign clinical course and no CT progression of the dissection, even without anticoagulation or anti-platelet therapy. Based on our observation, patients with SISMAD can be treated conservatively without anticoagulation therapy.     

Long Non-coding RNA LINC-PINT and LINC00599 Polymorphisms are Associated With High-altitude Pulmonary Edema in Chinese

BackgroundHigh-altitude pulmonary edema (HAPE) is a kind of non-cardiogenic edema with high incidence and life-threatening. This study was designed to explore the association of LINC-PINT and LINC00599 polymorphisms with HAPE susceptibility.MethodsThis study included 244 HAPE patients and 243 age-, sex-matched healthy controls from the Chinese population. The genotypes of polymorphisms were detected using the Agena MassARRAY. The relationship between polymorphisms and HAPE risk was evaluated using a χ² test with an odds ratio (OR) and 95% confidence intervals (CIs) in multiple genetic models.ResultsWe observe a significant association between the rs157928 and decreased HAPE risk in genotype model (OR = 0.65, 95% CI = 0.43–0.98, p = 0.038). The subgroup analysis results indicated that rs2272026 was associated with a decreased risk of HAPE in younger patients with age ≤32 (codominant model: p = 0.006; recessive model: p = 0.005 additive model: p = 0.018; and allele model: p = 0.012; rs72625676, codominant model: p = 0.038; recessive model: p = 0.037). Among patients older than 32 years, there was a significantly increased risk of HAPE associated with the rs2272026 and rs1962430 (rs2272026: genotype model: p = 0.049; recessive model: p = 0.029; rs1962430: genotype model: p = 0.024; recessive model: p = 0.020). Nevertheless, rs157928 had relationship with significantly reducing the risk of HAPE in the genotype model (p = 0.018).ConclusionOur study suggests that LINC-PINT and LINC00599 polymorphisms are associated with HAPE susceptibility in Chinese population.     

Pediatric burn-trauma patients have increased length of stay compared to trauma-only patients: A propensity matched analysis

BackgroundTrauma is the leading cause of mortality in children. Burn injury involves intensive resources, especially in pediatric patients. We hypothesized that among pediatric trauma patients, combined burn-trauma (BT) patients have increased length of stay (LOS) and mortality compared to trauma-only (T) patients.MethodsThe Pediatric Trauma Quality Improvement Program (2014–2016) was queried and BT patients were 1:2 propensity-score-matched to T patients based on age, gender, hypotension on admission, injury type and severity.Results93 BT patients were matched to 186 T patients. There were no differences in matched characteristics. BT patients had a longer median LOS (4 vs 2 days, p < 0.001) with no difference in mortality (1.1% vs 1.1%, p = 1.00), intensive care unit (ICU) LOS (3 vs 3 days, p = 0.55), or complications including decubitus ulcer (0% vs 1.1%, p = 0.32), deep vein thrombosis (0% vs 0.5%, p = 0.48), extremity compartment syndrome (1.1% vs 0%, p = 0.16), and urinary tract infection (1.1% vs 1.1%, p = 1.00).ConclusionPediatric BT patients had twice the LOS compared to a matched group of pediatric T patients. There was no difference between the cohorts in ICU LOS, complications or mortality rate. When evaluating risk-stratified quality metrics such as LOS, concomitant burn injury should be incorporated.     

Combined flexor hallucis longus tendon transfer and gastrocnemius recession for reconstruction of gapped chronic achilles tendon ruptures

ObjectiveThe aim of this study was to assess the functional outcomes after a combined FHL transfer and a gastrocnemius recession for treatment of chronic ruptures of Achilles tendon with a gap and to investigate the patient's satisfaction about the great toe function after transfer.Material and methods19 patients with chronic rupture of the Achilles tendon with a gap were treated with a flexor halluces longus tendon transfer combined with a gastrocnemius recession, Clinical diagnosis depends on the presence of gap in the tendon on examination, inability of tip toe walking on the affected side and positive calf-squeeze test, MRI was used to confirm the clinical diagnosis. American Orthopedic Foot & Ankle Society hind foot score was used for assessment of the results.ResultsThe AOFAS score improved significantly from a mean of 65 preoperatively to 94 at the last follow up (p < 0.001), there was no significant difference in the final outcome between patients with FHL tendon weaved through the stump of the Achilles tendon and those with trans osseous tunnels, the mean AOFAS score at the last follow up was 94.2, 93.8 respectively, no patient complained of big toe dysfunction.ConclusionManagement of chronic rupture of the Achilles tendon with a gap with flexor halluces longus tendon transfer combined with a gastrocnemius recession is a safe and reliable method with a significantly improved functional outcome, muscle advancement through gastrocnemius recession decreases the length of the gap without affecting the muscle function, flexor halluces longus tendon transfer doesn't harm the big toe function.     

Assessment of foot posture: Correlation between different clinical techniques

BackgroundClinical evaluation of foot posture is necessary for assessing and treating patients with lower extremity dysfunction. Although several studies have explored the reliability and validity of different clinical techniques for the measurement of foot posture, there is limited research in studies investigating whether two or more such techniques correlate with each other.ObjectivesTo explore the correlations between the valgus and arch index measurements with the measurements of the navicular drop and drift in bipedal and single-leg stance.MethodsClinical measurements of the valgus index, the arch index, the navicular drop and drift were performed on the left foot of 26 healthy subjects in bipedal and in single-leg stance with 30° knee flexion.ResultsThe valgus index yielded moderate to strong correlations with the measurement of navicular drop (bipedal: r = 0.657, p < 0.001; single-leg stance: r = 0.613, p = 0.001) and small correlations with navicular drift (bipedal: r = 0.481, p = 0.13; single-leg stance: r = 0.335, p = 0.094). The arch index demonstrated small correlations with the navicular drop and drift in both bipedal and single-leg stance (r = 0.317-0.428, p = 0.115–0.029).ConclusionsAlthough strong associations were obtained between the valgus index and the navicular drop, all other correlations demonstrated low degrees of association. Further research should explore the association of these clinical measurements in patients with foot/lower limb impairments.     

Daily serum creatinine monitoring promotes earlier detection of acute kidney injury in children and adolescents with cystic fibrosis

BackgroundThe epidemiology of aminoglycoside-associated acute kidney injury (AG-AKI) has not been well described in pediatric patients with cystic fibrosis (CF). We aimed to assess the impact of daily serum creatinine (SCr) measurement on detection of AG-AKI at our institution.MethodsWe examined a cohort of hospitalized patients with CF who received an intravenous (IV) aminoglycoside for ≥ 3 days. We compared the rate, timing, and medical management surrounding detection of AG-AKI during 2 periods: January 2010–May 2011 (Era 1, SCr measured at the discretion of the medical team, N = 124) and June 2011–June 2012 (Era 2, SCr measured daily, N = 103). Our primary outcome was detection of AG-AKI defined as ≥ 50% increase in SCr from baseline (lowest value in prior 6 months), or ≥ 0.3 mg/dL rise within 48 h, occurring after day 2.ResultsThe use of once daily tobramycin (p = 0.02) and IV fluids (p < 0.001) was higher during Era 2, while AG courses were shorter (p = 0.04), and fewer concomitant nephrotoxins (p = 0.04) were given; higher daily tobramycin doses (p < 0.001) were administered. Although the rate of AG-AKI was not significantly different (12% during Era 1 vs. 20% during Era 2, p = 0.09), the number of AG-AKI days detected increased (5.5 vs. 2.9 per 100 AG days, p = 0.003), and detection occurred earlier (median 6 vs. 9 days, log rank test p = 0.02) during the daily SCr period.ConclusionsDaily SCr measurement promoted earlier and increased detection of AG-AKI in patients with CF at our institution. We suggest systematic evaluation for AKI during aminoglycoside administration in patients with CF.     

Assessing the prevalence of protein-energy wasting in haemodialysis patients: A cross-sectional monocentric study

IntroductionProtein-energy wasting (PEW) is a strong predictive factor for morbidity and mortality in haemodialysis (HD) patients. However, there is no consensus for its assessment. The present study aimed to assess the nutritional status of patients on chronic HD by use of different nutritional assessment parameters, and at verifying which can identify the greatest number of HD patients with PEW. Also, to investigate predictors of nutritional status in a haemodialysis center in Morocco.Patients and methodsThis is a cross-sectional analysis performed on 126 patients aged 44.82 ± 14.01 years, undergoing maintenance HD in the Department of nephrology of the university hospital centre of Casablanca, Morocco. Energy and nutrients intake assessment was obtained by a three-day period food recall. Biochemical parameters, bioelectric impedance analysis, and subjective global assessment (SGA), have been performed to assess nutritional status.ResultsAccording to SGA the prevalence of PEW was 74.62%. However, when using the ISRMN malnutrition criteria only 36.50% of the patients were diagnosed with PEW. Pearson correlation showed a negative association between the degree of malnutrition evaluated by SGA and serum prealbumin (r = −0.54; P = 0.0001), serum albumin (r = −0.50; P = 0.001), energy (r = −0.34; P = 0.002), protein intake (r = −0.41; P = 0.0001), and a significant positive correlation with CRP (r = 0.65; P = 0.0001) was determined, but not with anthropometric measurements nor lipids profile. The areas under the receiver operating characteristic curve were 0.841 (95% CI: 0.751–0.932) for serum prealbumin, and 0.737 (95% CI: 0.634–0.840) for serum albumin.ConclusionOur results showed a high prevalence of PEW among Haemodialysis patients. Also, our findings suggest that SGA, serum albumin and prealbumin may be relative appropriate and practical markers for assessing nutritional status in HD patients.     

Prospective randomized clinical trial of aggressive rehabilitation after acute Achilles tendon ruptures repaired with Dresden technique

BackgroundRupture of the Achilles tendon is a common injury during working years. Aggressive rehabilitation may provide better outcomes, but also a greater chance of re-rupture.ObjectiveTo determine if aggressive rehabilitation has better clinical outcomes for Achilles tendon function, Triceps surae function, one-leg heel rise capacity and lower complication rate during twelve weeks after percutaneous Achilles tendon repair compared to conventional rehabilitation.DesignRandomized controlled trial.MethodThirty-nine patients were prospectively randomized. The aggressive group (n = 20, 41.4 ± 8.3 years) received rehabilitation from the first day after surgery. The conventional group (n = 19, 41.7 ± 10.7 years) rested for 28 days, before rehabilitation started. The statistical parameters were the Achilles tendon rupture score (ATRS), verbal pain scale, time to return to work, pain medication consumption, Achilles tendon strength, dorsiflexion range of motion (RoM), injured-leg calf circumference, calf circumference difference, one-leg heel rise repetition and difference, re-rupture rate, strength deficit rate, and other complication rates. Mixed-ANOVA and Bonferroni's post hoc test were performed for multiple comparisons. Student's t-test was performed for parameters measured on the 12th week.ResultsThe aggressive group with respect to the conventional group had a higher ATRS; lower verbal pain score; lower pain medication consumption; early return to work; higher Achilles tendon strength; higher one-leg heel rise repetitions; and lower one-leg heel rise difference. The re-rupture rate was 5% and 5%, the strength deficit rate was 42% and 5%, and other complications rate was 11% and 15% in the conventional and aggressive group, respectively.ConclusionPatients with Dresden repair and aggressive rehabilitation have better clinical outcomes, Achilles tendon function and one-leg heel rise capacity without increasing the postoperative complications rate after 12 weeks compared to rehabilitation with immobilization and non-weight-bearing during the first 28 days after surgery.     

Hallux rigidus: A cross-sectional study to evaluate clinical parameters

BackgroundHallux rigidus (HR) is a common condition with history and physical examination used to help evaluate pathology, grade clinical changes and to inform treatment.MethodA cross-sectional study was undertaken to evaluate the demographics of and clinical parameters encountered in HR. In 110 subjects (180 feet) aged 18–70 years (mean 52 years) a standardized history and physical examination was undertaken. Clinical parameters associated with HR were evaluated. The Foot Health Status Questionnaire (FHSQ) was used to measure health-related quality-of-life dimensions.ResultsSeventy (64%) subjects had bilateral HR and 73 (66%) were female. Mean HR onset was 44 (14–68 years) years and median HR duration 6 years (1–33 years). A history of 1st MTPJ trauma presented in 22% of subjects; 74% of whom had unilateral HR. Eighty-four (47%) feet had pes planus based on a positive Foot Posture Index. A correlation between pes planus and 1st MTPJ pain was found (r = 0.84, p = 0.05). In 74% of feet, hallux abductus interphalangeus angle (HAI°) was greater than normal (≤10°). A correlation between HAI and reduced 1st MTPJ ROM was found (r = 0.92, p = 0.05). Second toe length was the same as the hallux in 111 feet (62%). A correlation between valgus hallucal rotation and 1st MTP joint pain in HR was found (r = .78, p = .05). A positive relationship was found between 2nd toe length and 1st MTPJ pain (p = 0.001 < 0.05). A correlation between hallucal interphalangeal joint (IPJ) hyperextension and 1st MTPJ pain was found (r = 0.78, p = 0.01). A positive relationship was found between lesser MTPJ pain and supination at propulsion (p < 0.001). There was no evidence of Achilles tendon contracture. The FHSQ results concur with clinical findings.ConclusionsHR was associated with female gender, bilateral involvement, older age groups, increased HAI°, 2nd toe length similar to hallux, hallucal IPJ hyperextension, lesser MTP joint pain, flat foot and certain gait alterations. HR was not associated with Achilles tendon tightness or footwear. The content validity of clinical parameters of HR needs to be established by formal research prior to their inclusion in a classification of HR.
