AbstractObjectiveTo determine whether favorable changes to lean tissue mass (LTM), resting energy expenditure (REE), and testosterone (T) that occurred with 12 months of physiological testosterone replacement therapy (TRT) were retained 6 months after discontinuing treatment.DesignProspective, open-label, controlled drug intervention trial.SettingMetropolitan area hospitals.SubjectsEugonadal (n = 11) and hypogonadal (n = 13) men with chronic spinal cord injury (SCI).InterventionsHypogonadal subjects received a 5 or 10 mg transdermal T patch daily for 12 months, with adjustment of the dose to normalize the serum T concentration; TRT was discontinued after 12 months (TRT-12M) and subjects were followed for an additional 6 months and re-evaluated (Post-TRT). Total body dual energy X-ray absorptiometry and blood draws were performed at baseline (BL) prior to TRT, TRT-12M, and Post-TRT. Eugonadal subjects did not receive treatment and were evaluated at comparable time points.ResultsThere were no significant differences between groups prior to TRT at BL for any of the study endpoints. In the hypogonadal group, a significant increase in LTM was observed from BL to TRT-12M (50.2 ± 7.4 vs. 52.9 ± 6.8 kg, P < 0.01), which persisted Post-TRT compared to BL (52.2 ± 7.8 kg, P < 0.05). The increase in REE from BL to TRT-12M (1283 ± 246 vs. 1410 ± 250 kcal/day) was also retained at Post-TRT (1393 ± 220 kcal/day). These sustained improvements in LTM and REE after termination of anabolic hormonal therapy may be associated with persistent beneficial effects on health and physical function of hypogonadal men with chronic SCI. 相似文献

Objective
To document the effects of underwater treadmill training (UTT) on leg strength, balance, and walking performance in adults with incomplete spinal cord injury (iSCI).Design
Pre-test and post-test design.Setting
Exercise physiology laboratory.Participants
Adult volunteers with iSCI (n = 11).Intervention
Participants completed 8 weeks (3 × /week) of UTT. Each training session consisted of three walks performed at a personalized speed, with adequate rest between walks. Body weight support remained constant for each participant and ranged from 29 to 47% of land body weight. Increases in walking speed and duration were staggered and imposed in a gradual and systematic fashion.Outcome measures
Lower-extremity strength (LS), balance (BL), preferred and rapid walking speeds (PWS and RWS), 6-minute walk distance (6MWD), and daily step activity (DSA).Results
Significant (P < 0.05) increases were observed in LS (13.1 ± 3.1 to 20.6 ± 5.1 N·kg−1), BL (23 ± 11 to 32 ± 13), PWS (0.41 ± 0.27 to 0.55 ± 0.28 m·s−1), RWS (0.44 ± 0.31 to 0.71 ± 0.40 m·s−1), 6MWD (97 ± 80 to 177 ± 122 m), and DSA (593 ± 782 to 1310 ± 1258 steps) following UTT.Conclusion
Physical function and walking ability were improved in adults with iSCI following a structured program of UTT featuring individualized levels of body weight support and carefully staged increases in speed and duration. From a clinical perspective, these findings highlight the potential of UTT in persons with physical disabilities and diseases that would benefit from weight-supported exercise. 相似文献3.

Objective
To determine the day-to-day reliability of blood pressure responses during a sit-up test in individuals with a traumatic spinal cord injury (SCI).Design
Within-subject, repeated measures design.Setting
Community outpatient assessments at a research laboratory at the University of British Columbia.Participants
Five men and three women with traumatic SCI (age: 31 ± 6 years; C4-T11; American Spinal Injury Association Impairment Scale A-B; 1–17 years post-injury).Outcome measure
Maximum change in systolic (ΔSBP) and diastolic (ΔDBP) blood pressure upon passively moving from a supine to seated position.Results
The average values for ΔSBP were –11 ± 13 mmHg (range –38 to 3 mmHg) for visit 1, and −12 ± 8 mmHg (range −26 to −1 mmHg) for visit 2. The average values for ΔDBP were −9 ± 8 mmHg (range -21 to 0 mmHg) for visit 1, and –13 ± 8 mmHg (range –29 to –3 mmHg) for visit 2. The ΔSBP demonstrated substantial reliability with an intraclass correlation coefficient of 0.79 (P = 0.006; 95% CI 0.250–0.953), while the ΔDBP demonstrated almost perfect reliability with an intraclass correlation coefficient of 0.92 (P < 0.001; 95% CI 0.645–0.983). The smallest detectable differences in ΔSBP and ΔDBP were 7 mmHg and 6 mmHg, respectively.Conclusion
Blood pressure responses to the sit-up test are reliable in individuals with SCI, which supports its implementation as a practical bedside assessment for orthostatic hypotension in this at risk population. 相似文献4.

BACKGROUND:
Proximal interphalangeal joint (PIPJ) contracture is a difficult problem to treat regardless of etiology. Although numerous interventions have been recommended, published results are mediocre at best.OBJECTIVE:
The authors describe their experience and results of using a modification of pins and rubber band traction (PRBT) – applying a dynamic extension apparatus to a contracted PIPJ using the constant traction force in a stretched rubber (elastic) band.METHOD:
A retrospective review of patients treated with this method was performed, and the results are presented. The technique itself is described, and clinical photographs illustrate the method.RESULTS:
Mean PIPJ flexion contracture before PRBT was 82° (range 60° to 110°). The full correction of eight contracted PIPJs in seven patients was achieved, in a mean of 17.8 days (range 14 to 31 days). At one month postremoval of PRBT, the mean PIPJ flexion contracture was 22.8° (range 0° to 46°).DISCUSSION:
The method is compared with previously described methods of PIPJ contracture correction, whether surgical or splinting; the latter may be static, dynamic or a combination of the two. The results of previously published studies are discussed and compared with the method described.CONCLUSION:
The present method is a powerful and effective simplification of a previously described method of correcting PIPJ contractures. This technique is simple, ‘low-tech’ and can be applied under local anesthetic; the authors believe it offers a useful adjunct to surgical release. 相似文献5.

Objective
To determine the effectiveness of a melatonin agonist for treating sleep disturbances in individuals with tetraplegia.Design
Placebo-controlled, double-blind, crossover, randomized control trial.Setting
At home.Participants
Eight individuals with tetraplegia, having an absence of endogenous melatonin production and the presence of a sleep disorder.Interventions
Three weeks of 8 mg of ramelteon (melatonin agonist) and 3 weeks of placebo (crossover, randomized order) with 2 weeks of baseline prior to and 2 weeks of washout between active conditions.Outcome
Change in objective and subjective sleep.Measures
Wrist actigraphy, post-sleep questionnaire, Stanford sleepiness scale, SF-36.Results
We observed no consistent changes in either subjective or objective measures of sleep, including subjective sleep latency (P = 0.55, Friedman test), number of awakenings (P = 0.17, Friedman test), subjective total sleep time (P = 0.45, Friedman test), subjective morning alertness (P = 0.35, Friedman test), objective wake after sleep onset (P = 0.70, Friedman test), or objective sleep efficiency (P = 0.78, Friedman test). There were significant increases in both objective total sleep time (P < 0.05, Friedman test), subjective time in bed (P < 0.05, Friedman test), and subjective sleep quality (P < 0.05, Friedman test), although these occurred in both arms. There were no significant changes in any of the nine SF-36 subscale scores (Friedman test, Ps >Bonferroni adjusted α of 0.005).Conclusion
In this pilot study, we were unable to show effectiveness of pharmacological replacement of melatonin for the treatment of self-reported sleep problems in individuals with tetraplegia.Trial Registration

Background
Idiopathic clubfoot correction is commonly performed using the Ponseti method and is widely reported to provide reliable results. However, a relapsed deformity may occur and often is treated in children older than 2.5 years with repeat casting, followed by an anterior tibial tendon transfer. Several techniques have been described, including a whole tendon transfer using a two-incision technique or a three-incision technique, and a split transfer, but little is known regarding the biomechanical effects of these transfers on forefoot and hindfoot motion.Questions/purpose
We used a cadaveric foot model to test the effects of three tibialis anterior tendon transfer techniques on forefoot positioning and production of hindfoot valgus.Methods
Ten fresh-frozen cadaveric lower legs were used. We applied 150 N tension to the anterior tibial tendon, causing the ankle to dorsiflex. Three-dimensional motions of the first metatarsal, calcaneus, and talus relative to the tibia were measured in intact specimens, and then repeated after each of the three surgical techniques.Results
Under maximum dorsiflexion, the intact specimens showed 6° (95% CI, 2.2°–9.4°) forefoot supination and less than 3° (95% CI, 0.4°–5.3°) hindfoot valgus motion. All three transfers provided increased forefoot pronation and hindfoot valgus motion compared with intact specimens: the three-incision whole transfer provided 38° (95% CI, 33°–43°; p < 0.01) forefoot pronation and 10° (95% CI, 8.5°–12°; p < 0.01) hindfoot valgus; the split transfer, 28° (95% CI, 24°–32°; p < 0.01) pronation, 9° (95% CI, 7.5°–11°; p < 0.01) valgus; and the two-incision transfer, 25° (95% CI, 20°–31°; p < 0.01) pronation, 6° (95% CI, 4.2°–7.8°; p < 0.01) valgus.Conclusion
All three techniques may be useful and deliver varying degrees of increased forefoot pronation, with the three-incision whole transfer providing the most forefoot pronation. Changes in hindfoot motion were small.Clinical Relevance
Our study results show that the amount of forefoot pronation varied for different transfer methods. Supple dynamic forefoot supination may be treated with a whole transfer using a two-incision technique to avoid overcorrection, while a three-incision technique or a split transfer may be useful for more resistant feet. Confirmation of these findings awaits further clinical trials. 相似文献7.
Objective
To compare the nutritional intake of patients with acute and chronic spinal cord injury (SCI).Design
Cross-sectional, observational study.Setting
Spinal cord unit.Methods
Twelve in-house patients of a spinal cord unit with acute SCI and paralysis duration of 5.3 ± 2.5 months (acute group) were compared with 12 subjects with chronic SCI (chronic group) with lesion duration of 55.5 ± 21.0 months. All subjects recorded their nutritional intake for 7 days, which was analyzed for intake of energy, proteins, fat, carbohydrates, vitamins, mineral nutrients, fluid, and dietary fiber. Resting energy expenditure (REE) and total body fat were also determined.Results
The chronic group showed a significantly higher total body fat content compared to the acute group (19.4 ± 3.8 vs. 15.7 ± 4.3%). All other parameters were not significantly different between groups. Both groups ingested excessive fat and insufficient amounts of carbohydrates compared with common nutritional recommendations. Low intakes of vitamins C, D, E, biotin, folic acid, as well as potassium and iron were found.Conclusions
No differences were found in the nutritional intakes of two comparable groups of subjects with acute and chronic SCI. Independent of lesion duration, subjects with SCI showed considerable deviations from the general accepted nutritional recommendations concerning macro- and micronutrients intake. Professional nutritional education for persons with SCI should start as soon as possible after injury to prevent nutrition-related secondary complications like cardiovascular diseases. Periodic determinations of body fat content and REE combined with a physical activity program might be helpful as well. 相似文献8.

Background/Objective:
It is suspected that the speed of the motion of the spinal cord under static compression may be the cause of spinal cord injury (SCI). However, little is known about the relationship between the speed of the motion of the spinal cord and its stress distributions. The objective was to carry out a biomechanical study of SCI in patients with ossification of the longitudinal ligament without radiologic evidence of injury.Methods:
A 3-dimensional finite element spinal cord model was established. After the application of static compression, the model underwent anterior flexion to simulate SCI in ossification of the longitudinal ligament patients without radiologic abnormality. Flexion of the spine was assumed to occur at 1 motor segment. Flexion angle was 5°, and flexion speeds were 0.5°/s, 5°/s, and 50°/s. Stress distributions inside of the spinal cord were evaluated.Results:
Stresses on the spinal cord increased slightly after the application of 5° of flexion at a speed of 0.5°/s. Stresses became much higher at a speed of 5°/s and increased further at 50°s.Conclusions:
The stress distribution of the spinal cord under static compression increased with faster flexion speed of the spinal cord. High-speed motion of the spinal cord under static compression may be one of the causes of SCI in the absence of radiologic abnormality. 相似文献9.

Background:
Bone mineral density (BMD) of the lumbar spine (L-spine) has been reported to be normal by routine posterior-anterior (PA) bone density imaging in patients with chronic spinal cord injury (SCI).Objective:
To determine BMD of the L-spine by PA and lateral (LAT) dual-energy radiographic absorptiometry (DXA) in patients with chronic SCI.Design:
Prospective study.Setting:
Veterans Affairs Medical Center and a private rehabilitation facility.Methods:
Measurements of the PA and LAT L-spine and hip were performed in 15 patients with SCI: 9 with tetraplegia and 6 with paraplegia. The DXA (GE Lunar Advance DXA) images were obtained using standard software. Results are reported as mean ± SD.Results:
The mean age was 35 ± 15 years (range = 20–62 years), and the duration of injury was 57 ± 74 months (range = 3–240 months). T- and Z-scores were lower for the LAT L-spine than those for PA L-spine (T-scores L2: −0.7 ± 1.2 vs 0.0 ± 1.4, P < 0.01; L3: −0.9 ± 1.6 vs 0.3 ± 1.3, P < 0.002; L2-L3: −0.8 ± 1.3 vs 0.2 ± 1.3, P < 0.001; Z-scores L2: −0.3 ± 1.1 vs 0.2 ± 1.2, P < 0.05; L3: −0.6 ± 1.3 vs 0.5 ± 1.3, P < 0.01; L2-L3: −0.4 ± 1.1 vs 0.4 ± 1.2, P < 0.005). The T- and Z-scores for the total hip (−1.1 ± 1.0 and −1.0 ± 1.0, respectively) and L2-L3 LAT L-spine demonstrated remarkable similarity, whereas the L2-L3 PA L-spine scores were not reduced. Bone mineral density of the LAT L-spine, but not the PA L-spine, was significantly reduced with increasing duration of injury.Conclusions:
Individuals with SCI may have bone loss of the L-spine that is evident on LAT DXA that may be misdiagnosed by PA DXA, underestimating the potential risk of fracture. 相似文献10.

Context
Despite evidence that healthcare providers have implicit biases that can impact clinical interactions and decisions, implicit bias among physicians caring for individuals with spinal cord injury (SCI) has not been examined.Objective
Conduct a pilot study to examine implicit racial bias of SCI physicians and its association with functioning and wellbeing for individuals with SCI.Design
Combined data from cross-sectional surveys of individuals with SCI and their SCI physicians.Setting
Four national SCI Model Systems sites.Participants
Individuals with SCI (N = 162) and their SCI physicians (N = 14).Outcome measures
SCI physicians completed online surveys measuring implicit racial (pro-white/anti-black) bias. Individuals with SCI completed questionnaires assessing mobility, physical independence, occupational functioning, social integration, self-reported health, depression, and life satisfaction. We used multilevel regression analyses to examine the associations of physician bias and outcomes of individuals with SCI.Results
Physicians had a mean bias score of 0.62 (SD = 0.35), indicating a strong pro-white/anti-black bias. Greater physician bias was associated with disability among individuals with SCI in the domain of social integration (odds ratio = 4.80, 95% confidence interval (CI) = 1.44, 16.04), as well as higher depression (B = 3.24, 95% CI = 1.06, 5.41) and lower life satisfaction (B = −4.54, 95% CI= −8.79, −0.28).Conclusion
This pilot study indicates that SCI providers are susceptible to implicit racial bias and provides preliminary evidence that greater implicit racial bias of physicians is associated with poorer psychosocial health outcomes for individuals with SCI. It demonstrates the feasibility of studying implicit bias among SCI providers and provides guidance for future research on physician bias and patient outcomes. 相似文献12.

Objective
To investigate risk factors for pneumonia in patients with traumatic lower cervical spinal cord injury.Design
Observational study, retrospective study.Setting
Spinal cord unit in a maximum care hospital.Methods
Thirty-seven patients with acute isolated traumatic spinal cord injury at levels C4–C8 and complete motor function injury (AIS A, B) treated from 2004 to 2010 met the criteria for inclusion in our retrospective analysis. The following parameters were considered: ventilation-specific parameters, re-intubation, creation of a tracheostomy, pneumonia, antibiotic treatment, and length of intensive care unit (ICU) stay and total hospitalization.Results
Among the patients, 81% had primary invasive ventilation. In 78% of cases a tracheostomy was created; 3% of these cases were discharged with invasive ventilation and 28% with a tracheostomy without ventilation. Pneumonia according to Centers for Disease Control criteria occurred in 51% of cases within 21 ± 32 days of injury, and in 3% at a later date. The number of pre-existing conditions was significantly associated with pneumonia. Length of ICU stay was 25 ± 34 days, and average total hospital duration was 230 ± 144 days. Significant factors affecting the duration of ventilation were the number of pre-existing conditions and tetraplegia-specific complications.Conclusions
Our results confirm that patients with traumatic lower cervical spinal cord injuries defined by lesion level and AIS constitute a homogeneous group. This group is characterized by a high rate of pneumonia during the first 4 weeks after injury. The number of pre-existing general conditions and spinal injury-specific comorbidities are the only risk factors identified for the development of pneumonia and/or duration of ventilation. 相似文献13.

Background
Distal radius fractures are common, costly, and increasing in incidence. Percutaneous K-wire fixation and volar locking plates are two of the most commonly used surgical treatments for unstable dorsally displaced distal radius fractures. However, there is uncertainty regarding which of these treatments is superior.Questions/purposes
We performed a meta-analysis of randomized controlled trials to determine whether patients treated with volar locking plates (1) achieved better function (2) attained better wrist motion, (3) had better radiographic outcomes, and (4) had fewer complications develop than did patients treated with K-wires for dorsally displaced distal radius fractures.Methods
We performed a comprehensive search of MEDLINE (inception to 2014, October Week 2), EMBASE (inception to 2014, Week 42), and the Cochrane Central Register of Controlled Trials to identify relevant randomized controlled trials; we supplemented these searches with manual searches. We included studies of extraarticular and intraarticular distal radius fractures. Adjunctive external fixation was acceptable as long as the intent was to use only K-wires where possible and external fixation was used in less than 25% of the procedures. We considered a difference in the DASH scores of 10 as the minimal clinically important difference. We performed quality assessment with the Cochrane Risk of Bias tool and evaluated the strength of recommendations using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. Seven randomized trials with a total of 875 participants were included in the meta-analysis.Results
Patients treated with volar locking plates had slightly better function than did patients treated with K-wires as measured by their DASH scores at 3 months (mean difference [MD], 7.5; 95% CI, 4.4–10.6; p < 0.001) and 12 months (MD, 3.8; 95% CI, 1.2–6.3; p = 0.004). Neither of these differences exceeded the a priori-determined threshold for clinical importance (10 points). There was a small early advantage in flexion and supination in the volar locking plate group (3.7° [95% CI, 0.3°–7.1°; p = 0.04] and 4.1° [95% CI, 0.6°–7.6°; p = 0.02] greater, respectively) at 3 months, but not at later followups (6 or 12 months). There were no differences in radiographic outcomes (volar tilt, radial inclination, and radial height) between the two interventions. Superficial wound infection was more common in patients treated with K-wires (8.2% versus 3.2%; RR = 2.6; p = 0.001), but otherwise no difference in complication rates was found.Conclusions
Despite the small number of studies and the limitations inherent in a meta-analysis, we found that volar locking plates show better DASH scores at 3- and 12-month followups compared with K-wires for displaced distal radius fractures in adults; however, these differences were small and unlikely to be clinically important. Further research is required to better delineate if there are specific radiographic, injury, or patient characteristics that may benefit from volar locking plates in the short term and whether there are any differences in long-term outcomes and complications.Level of Evidence

Objective
The objective of this study was to compare the safety, efficacy, quality-of-life impact, and costs of a single dose or a longer course of pre-procedural antibiotics prior to elective endoscopic urological procedures in individuals with spinal cord injury and disorders (SCI/D) and asymptomatic bacteriuria.Design

Sixty persons with SCI/D and asymptomatic bacteriuria scheduled to undergo elective endoscopic urological procedures.Interventions
A single pre-procedural dose of antibiotics vs. a 3–5-day course of pre-procedural antibiotics.Outcome measures
Objective and subjective measures of health, costs, and quality of life.Results
There were no significant differences in vital signs, leukocytosis, adverse events, and overall satisfaction in individuals who received short-course vs. long-course antibiotics. There was a significant decrease in antibiotic cost (33.1 ± 47.6 vs. 3.6 ± 6.1 US$, P = 0.01) for individuals in the short-course group. In addition, there was greater pre-procedural anxiety (18 vs. 0%, P < 0.05) for individuals who received long-course antibiotics.Conclusion
SCI/D individuals with asymptomatic bacteriuria may be able to safely undergo most endoscopic urological procedures with a single dose of pre-procedural antibiotics. However, further research is required and even appropriate pre-procedural antibiotics may not prevent severe infections. 相似文献16.

Background
Total shoulder arthroplasty (TSA) provides excellent functional outcomes and pain relief in appropriately selected patients. Although it is known to affect other shoulder conditions, the role of hand dominance after TSA has not been reported, to our knowledge.Questions/Purposes
We asked: (1) Does TSA of the dominant arm result in greater postoperative ROM compared with TSA of the nondominant arm? (2) Does hand dominance affect validated outcome scores after TSA?Methods
We performed a review of all patients who underwent primary TSAs between 2008 and 2011 with a minimum of 12 months followup. During that time, one surgeon performed 156 primary TSAs. One hundred twenty-seven patients met the minimum followup requirement for this analysis (81%), whereas 29 (19%) were lost to followup. Seven patients were excluded for surgical indications other than glenohumeral osteoarthritis. A total of 58 patients underwent TSA of the dominant upper extremity and 62 underwent TSA of the nondominant upper extremity. Patient demographics, preoperative and postoperative ROM, and preoperative and postoperative outcome scores, were collected from the medical records. Student’s t-tests and chi-square tests were used for analysis. Demographics and preoperative ROM did not differ between patients undergoing TSA on the dominant or the nondominant upper extremity.Results
Dominant-arm TSAs showed greater postoperative forward elevation and external rotation. Postoperative active forward elevation in the dominant group was 151° versus 141° in the nondominant group (mean difference, 10°; 95% CI, 1°–18°; p = 0.033). Postoperative active external rotation was 61° in the dominant group, versus 51° in the nondominant group (mean difference, 10°; 95% CI, 5°–15°; p < 0.001). Active internal rotation did not differ (dominant, 52°, nondominant, 50°; mean difference, 2°; 95% CI, −3° to 7°; p = 0.419). There were no differences in postoperative VAS (dominant, 0.9, nondominant, 1.4; mean difference, 0.5; 95% CI, −0.1 to 1.1; p = 0.129), simple shoulder test (dominant, 9.8, nondominant, 9.2; mean difference, 0.5; 95% CI, −0.5 to 1.5; p = 0.278), and American Shoulder and Elbow Surgeons scores (dominant, 84, nondominant, 80; mean difference, 4; 95% CI, −2 to 10; p = 0.211).Conclusions
Patients who underwent TSA of their dominant upper extremity had greater postoperative active forward elevation and active external rotation compared with patients who had TSA of their nondominant upper extremity. This average difference of 10° active forward elevation and active external rotation could be useful for preoperative and postoperative counseling of patients. Regardless of hand dominance, similar functional outcomes were achieved.Level of Evidence

Objective
Stiffness and viscosity represent passive resistances to joint motion related with the structural properties of the joint tissue and of the musculotendinous complex. Both parameters can be affected in patients with spinal cord injury (SCI). The purpose of this study was to measure passive knee stiffness and viscosity in patients with SCI with paraplegia and healthy subjects using Wartenberg pendulum test.Design
Non-experimental, cross-sectional, case–control design.Setting
An outpatient physical therapy clinic, University of social welfare and Rehabilitation Science, Iran.Patients
A sample of convenience sample of 30 subjects participated in the study. Subjects were categorized into two groups: individuals with paraplegic SCI (n = 15, age: 34.60 ± 9.18 years) and 15 able-bodied individuals as control group (n = 15, age: 30.66 ± 11.13 years).Interventions
Not applicable.Main measures
Passive pendulum test of Wartenberg was used to measure passive viscous-elastic parameters of the knee (stiffness, viscosity) in all subjects.Results
Statistical analysis (independent t-test) revealed significant difference in the joint stiffness between healthy subjects and those with paraplegic SCI (P = 0.01). However, no significant difference was found in the viscosity between two groups (P = 0.17). Except for first peak flexion angle, all other displacement kinematic parameters exhibited no statistically significant difference between normal subjects and subjects with SCI.Conclusions
Patients with SCI have significantly greater joint stiffness compared to able-bodied subjects. 相似文献18.

Background
The aim of this study was to evaluate causes of unstable total knee arthroplasty and results of revision surgery.Methods
We retrospectively reviewed 24 knees that underwent a revision arthroplasty for unstable total knee arthroplasty. The average follow-up period was 33.8 months. We classified the instability and analyzed the treatment results according to its cause. Stress radiographs, postoperative component position, and joint level were measured. Clinical outcomes were assessed using the Hospital for Special Surgery (HSS) score and range of motion.Results
Causes of instability included coronal instability with posteromedial polyethylene wear and lateral laxity in 13 knees, coronal instability with posteromedial polyethylene wear in 6 knees and coronal and sagittal instability in 3 knees including post breakage in 1 knee, global instability in 1 knee and flexion instability in 1 knee. Mean preoperative/postoperative varus and valgus angles were 5.8°/3.2° (p = 0.713) and 22.5°/5.6° (p = 0.032). Mean postoperative α, β, γ, δ angle were 5.34°, 89.65°, 2.74°, 6.77°. Mean changes of joint levels were from 14.1 mm to 13.6 mm from fibular head (p = 0.82). The mean HSS score improved from 53.4 to 89.2 (p = 0.04). The average range of motion was changed from 123° to 122° (p = 0.82).Conclusions
Revision total knee arthroplasty with or without a more constrained prosthesis will be a definite solution for an unstable total knee arthroplasty. The solution according to cause is very important and seems to be helpful to avoid unnecessary over-constrained implant selection in revision surgery for total knee instability. 相似文献19.
