RESUMO
INTRODUCTION: This study aimed to assess cost-effectiveness of shoulder arthroplasty for osteoarthritis (OA) and rotator cuff tear arthropathy (CTA) from the perspective of a publicly funded health care system using patient data, health utilities and costs from a real-world situation. HYPOTHESIS: Our hypothesis was that arthroplasty for OA is more cost-effective than for CTA. MATERIAL AND METHODS: We gathered a cohort of patients with 153 anatomic total shoulder arthroplasty (TSA) for OA and 107 reverse shoulder arthroplasty (RSA) for CTA between years 2016-2020 at a university hospital. Short-term (mean 2.8years) shoulder function, health utilities and costs were obtained from prospectively collected data, and a Markov cohort simulation was carried out to assess lifetime cost-utility. The primary outcome measures were change in 15D score to calculate gain in quality-adjusted life years (QALYs) and change in Western Ontario osteoarthritis score of the shoulder (WOOS). RESULTS: Both TSA and RSA restored shoulder function well, WOOS improvement was 59.7 (95% CI: 56.2-63.2) and 55.8 (95% CI: 50.4-61.2), respectively. The cost/QALY gained was 20,846.82 for TSA and 38,711.90 for RSA. The cost-utility was not remarkable sensitive to costs, discounting of future costs or estimated revision rates. However, the cost-effectiveness was very sensitive to change in 15D health utility scores and thus QALY gain, especially for RSA patients. DISCUSSION: Shoulder arthroplasty restores shoulder function well in both OA and CTA. In health economic terms, RSA is less cost-effective than TSA in an everyday setting, mainly due to inferior improvement of health-related quality-of-life and reduced life expectancy of CTA patients. LEVEL OF EVIDENCE: III; case series.
RESUMO
INTRODUCTION: The incidence of olecranon fractures is growing in the elderly population. The traditional operative approach is giving way among the elderly to conservative treatment, which seems to provide a comparable functional outcome with a lower complication burden. However, there is still a lack of reliable evidence to support this shift.The objective of this trial is to investigate whether conservative treatment of displaced olecranon fractures in patients aged 75 or older yields comparable results to those of operative treatment in terms of pain and daily function. METHODS AND ANALYSIS: Scandinavian Olecranon Research in the Elderly (SCORE) is a randomised, controlled, multicentre, non-inferiority trial. Eligible patients will be randomised to either conservative or operative treatment. The sample size will be 68 patients and allocation done at a 1:1 ratio (34 patients per group). The randomisation is stratified according to the participating hospital and patient's sex. Both groups will receive the same postoperative physiotherapy and pain management. The primary outcome is Disabilities of the Arm, Shoulder and Hand at 1-year follow-up. Secondary outcomes are pain and satisfaction measured on visual analogue scales, Patient Reported Elbow Evaluation, range of motion of the elbow and extension strength of the elbow compared with the unaffected arm. Radiographs will be taken at each follow-up. Primary analysis of the results will be conducted on an intention-to-treat basis. ETHICS AND DISSEMINATION: The study protocol for this clinical trial has been approved by the Ethics Committee of the Hospital District of Southwest Finland and will be submitted for approval to the Regional Ethics Committees in Linköping, Sweden and Copenhagen, Denmark. Every recruiting centre will apply local research approvals. The results of this study will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04401462. PROTOCOL VERSION: This is the second protocol version dated on 16 April 2020.

OBJECTIVES: To compare the success rates of arthroscopic Bankart and open Latarjet procedure in the treatment of traumatic shoulder instability in young males. DESIGN: Multicentre randomised controlled trial. SETTING: Orthopaedic departments in eight public hospitals in Finland. PARTICIPANTS: 122 young males, mean age 21 years (range 16-25 years) with traumatic shoulder anteroinferior instability were randomised. INTERVENTIONS: Arthroscopic Bankart (group B) or open Latarjet (group L) procedure. MAIN OUTCOME MEASURES: The primary outcome measure was the reported recurrence of instability, that is, dislocation at 2-year follow-up. The secondary outcome measures included clinical apprehension, sports activity level, the Western Ontario Shoulder Instability Index, the pain Visual Analogue Scale, the Oxford Shoulder Instability Score, the Constant Score and the Subjective Shoulder Value scores and the progression of osteoarthritic changes in plain films and MRI. RESULTS: 91 patients were available for analyses at 2-year follow-up (drop-out rate 25%). There were 10 (21%) patients with redislocations in group B and 1 (2%) in group L, p=0.006. One (9%) patient in group B and five (56%) patients in group L returned to their previous top level of competitive sports (p=0.004) at follow-up. There was no statistically significant between group differences in any of the other secondary outcome measures. CONCLUSIONS: Arthroscopic Bankart operation carries a significant risk for short-term postoperative redislocations compared with open Latarjet operation, in the treatment of traumatic anteroinferior instability in young males. Patients should be counselled accordingly before deciding the surgical treatment. TRIAL REGISTRATION NUMBER: NCT01998048.

BACKROUND: The clinical relevance and treatment of syndesmosis injury in supination-external rotation (SER) ankle fractures are controversial. METHODS: After malleolar fixation 24 SER 4 ankle fracture patients with unstable syndesmosis in external rotation stress test were randomised to syndesmosis transfixation with a screw (13 patients) or no fixation (11 patients). Mean follow-up time was 9.7 years (range, 8.9-11.0). The primary outcome measure was the Olerud-Molander Ankle Outcome Score (OMAS). Secondary outcome measures included ankle mortise congruity and degenerative osteoarthritis, 100-mm visual analogue scale for function and pain, RAND 36-Item Health Survey, and range of motion. RESULTS: Mean OMAS in the syndesmosis transfixation group was 87.3 (SD 15.5) and in the no-syndesmosis-fixation group 89.0 (SD 16.0) (difference between means 1.8, 95% CI -10.4-14.0, P = 0.76). There were no differences between the two groups in secondary outcome measures. CONCLUSION: With the numbers available, SER 4 ankle fractures with unstable syndesmosis can be treated with malleolar fixation only, with good to excellent long-term functional outcome.

OBJECTIVE: Randomised controlled trials (RCT) with short-term follow-ups have shown that, in treatment of syndesmosis injuries, a suture button device (SB) resulted in better radiographic and functional outcome compared to syndesmosis screw fixation (SS). However, only one RCT has reported long-term results; thus, the syndesmosis malreduction rates for both implants might increase during longer follow-up. The primary objective of this RCT was to evaluate the maintenance of syndesmosis reduction with the SS compared to the SB fixation in patients during a minimum follow-up of 6-years. The secondary objectives were to assess the post-traumatic osteoarthritis (OA) grade and the functional outcome. PATIENTS AND METHODS: At Oulu University Hospital, between January 2010 and December 2011, we enrolled 43 patients with Lauge-Hansen pronation-external rotation type 4/Weber C, ankle fractures with unstable syndesmosis. Patients were randomised to treatment with either a single 3.5-mm tricortical SS (22 patients) or an SB (21 patients). The mean follow-up was 7.1 years (range, 6.2-7.9). Syndesmosis reduction and OA grade was assessed with standing cone-beam computed tomography (CBCT) of both ankles. Malreduction was defined as >2 mm side-to-side difference in the mean width of the syndesmosis. OA was graded according to the Morrey & Wiedeman classification. The Olerud-Molander Ankle Outcome Score (OMAS) and a quality of life questionnaire (RAND 36-Item Health Survey) were used to evaluate functional outcome. RESULTS: Two syndesmoses in the SS group and one in the SB group were malreduced (P = 0.58). Moderate OA after a mean of 7 years post-injury was common. In the SS and SB groups, 9 of 16 and 11 of 13 patients, respectively, had one or more grades serious OA in the injured ankle than in the uninjured ankle (P = 0.11). The mean OMAS was 88 in the SS group and 78 in the SB group (difference between means 7.1, 95% CI: -7.0-21.1, P = 0.32). The RAND-36 results did not differ between groups. CONCLUSION: The SS and SB maintained syndesmosis reduction equally well during follow-up. Our study findings also suggest that both methods result in moderate OA rates and the functional outcome is comparable between these two syndesmosis fixation methods.

BACKGROUND: Rotator cuff disease (RCD) causes prolonged shoulder pain and disability in adults. RCD is a continuum ranging from tendinopathy to full-thickness tendon tear. Recent studies have shown that subacromial decompression and non-surgical treatments provide equivalent results in RCD without a full-thickness tendon lesion. However, the importance of surgery for full-thickness tendon tears remains unclear. METHODS: In a pragmatic, randomised, controlled trial, 417 patients with subacromial pain underwent 3-month initial rehabilitation and MRI arthrography (MRA) for the diagnosis of RCD. Of these, 190 shoulders remained symptomatic and were randomised to non-surgical or surgical treatments. The primary outcomes were the mean changes in the Visual Analogue Scale for pain and the Constant Murley Score for shoulder function at the 2-year follow-up. RESULTS: At the 2-year follow-up, both non-surgical and surgical treatments for RCD reduced pain and improved shoulder function. The scores differed between groups by 4 (95% CI -3 to 10, p=0.25) for pain and 3.4 (95% CI -0.4 to 7.1, p=0.077) for function. Among patients with full-thickness ruptures, the reduction in pain (13, 95% CI 5 to 22, p=0.002) and improvement in function (7.0, 95% CI 1.8 to 12.2, p=0.008) favoured surgery. CONCLUSIONS: Non-surgical and surgical treatments for RCD provided equivalent improvements in pain and function. Therefore, we recommend non-surgical treatment as the primary choice for patients with RCD. However, surgery yielded superior improvement in pain and function for full-thickness rotator cuff rupture. Therefore, rotator cuff repair may be suggested after failed non-surgical treatment. TRIAL REGISTRATION DETAILS: ClinicalTrials.gov, NCT00695981 and NCT00637013.

OBJECTIVES: To assess the long-term functional and radiological outcome, as well as complications and reoperations of ankle fracture patients treated based on stability classification. DESIGN: Retrospective. SETTING: Main Trauma Center, University Hospital. PATIENTS AND INTERVENTIONS: One hundred sixty patients were treated based on stability classification. After a mean follow-up of 12 years, 102 patients were assessed; 67 visited the outpatient clinic, and standard standing ankle radiographs were taken; osteoarthritis (OA) was graded according to Kellgren-Lawrence classification. The remaining patients (n = 35) were followed up via mail or telephone. The complications and reoperations of all 160 patients were collected from electronic patient records. MAIN OUTCOME MEASURES: Olerud-Molander ankle score, foot and ankle outcome score, visual analog scale, RAND-36 item health survey, range-of-motion measurements, and Kellgren-Lawrence OA classification. RESULTS: Very good to excellent ankle functional outcome was reported by 96% of the stable fracture group [mean Olerud-Molander ankle score (OMAS), 92; range, 20-100] and 82% of the unstable group (mean OMAS, 86; range, 30-100). For patients with an unstable fracture, OMAS and VAS pain scores significantly improved from 2 to 12 years, even though higher grades of radiologic OA were found. No patients with fractures deemed stable needed operative intervention even in the long-term follow-up. Instead, 30% of the operatively treated patients underwent reoperation during the long follow-up. CONCLUSIONS: The treatment of ankle fractures based on stability-based classification led to predictable, functionally good outcomes even during long-term follow-up. Ankle fractures can reliably be deemed stable based on this classification and treated without failures in the long term. LEVEL OF EVIDENCE: Therapeutic Level III.

BACKGROUND: Postoperative infection is a severe complication after operative treatment of ankle fractures, associated with age, comorbidities, and severe soft tissue injuries. We assessed the efficacy of intramedullary fibular nailing for treating ankle fractures in patients at high risk of wound complications. METHODS: 41 high-risk patients were included in the study. We retrospectively reviewed the medical records to assess the risk profile, the treatment data, and possible infections and re-operations. After a minimum of 2 years eight patients had died, three had advanced-staged dementia and two were lost to follow-up. Remaining 28 patients reported the functional outcome and QoL through patient-reported questionnaires. Radiographs and cone-beam computed tomography were performed, as well as range-of-motion was measured. RESULTS: No surgical wound infections were found. The mean Olerud-Molander score was 67 points (SD 28 [20-100]). The osteoarthritis stages and the range-of-motion were significantly different between the injured and uninjured ankles, but we detected no significant effect on the QoL. CONCLUSION: Intramedullary fibular fixation appeared to be a safe treatment choice for ankle fractures in high-risk patients. LEVEL OF EVIDENCE: IV.

BACKGROUND: There is limited evidence that the Latarjet procedure has a worse outcome as a revision operation, after a failed stabilization surgery, compared with when it is the primary procedure for posttraumatic anteroinferior instability of the shoulder joint. PURPOSE: To compare the results from Latarjet as a primary operation vs. revision surgery after a failed arthroscopic Bankart repair for posttraumatic anteroinferior shoulder instability. In addition, to assess the effect of preoperative bony pathology on outcome. PATIENTS AND METHODS: Ninety-nine patients who underwent the Latarjet procedure (47 primary, 52 revision after failed Bankart repair) were analyzed after an average of 3.8 (SD 2.3, range 1-11) years of follow-up. All patients underwent either computed tomography or magnetic resonance imaging preoperatively. Glenoid and humeral bone defects were measured to assess whether the Hill-Sachs lesion was on- or off-track. Clinical outcome measures included the Western Ontario Shoulder Instability Index (WOSI), subjective shoulder value (SSV), and recurrence of instability (dislocation, subluxation, or any perception of instability). RESULTS: There were no cases of recurrent dislocation in either group. Four patients in the primary surgery group and 13 in the revision group had at least one subluxation or perception of instability after the Latarjet procedure. Patients with a previous arthroscopic Bankart repair had worse outcomes than those undergoing primary Latarjet when assessed by the WOSI: 76 (SD 22) vs. 85 (SD 15), difference in means -9 (95% CI -17 to -1, p=0.02); SSV: 80 (SD 18) vs. 88 (SD 13), difference in means -8 (95% CI -15 to -2, p=0.01); and the recurrence percentage (25% vs. 9%, p=0.03). A multivariate linear regression model adjusted for the length of follow-up, glenoid bone defect size, Hill-Sachs lesion size, and the frequency of preoperative bipolar bone defects (on/off track Hill-Sachs lesions) further increased the difference in WOSI to -12 (95% CI -21 to -4, p=0.005). DISCUSSION: A previous failed arthroscopic Bankart repair was a significant independent risk factor for inferior outcome. Preoperative bony pathology did not explain the worse outcome from the revision vs. primary Latarjet procedure. LEVEL OF EVIDENCE: IV, cohort observational study.

Background and purpose - There is no consensus regarding optimal treatment of displaced distal radius fractures (DRFs). We compared the results of 2 treatment protocols: early palmar plating vs. primary nonoperative treatment of displaced DRFs. Patients and methods - We performed a prospective randomized controlled study including 80 patients aged ≥ 50 years with dorsally displaced DRFs, excluding AO type C3 fractures. Patients were randomized to undergo either immediate surgery with palmar plating (n = 38), or initial nonoperative treatment (n = 42) after successful closed reduction in both groups. Delayed surgery was performed in nonoperatively treated patients showing early loss of alignment (n = 16). The primary outcome measure was Disabilities of the Arm, Shoulder, and Hand (DASH) score. Results - Mean DASH scores at 24 months in the early surgery group were 7.9 vs. 14 in the initial nonoperative group (difference between means 6, 95% CI 0.1-11, p = 0.05). Delayed operation was performed on 16/42 of patients due to secondary displacement in the initial nonoperative group. In "as treated" analysis, DASH scores were 7 in the early surgery group, 13 in the nonoperative group, and 17 after delayed surgery (p = 0.02). The difference in DASH scores between early and delayed surgery was 9 points (CI 0.3-19, p = 0.02) Interpretation - Treatment of DRFs with early palmar plating resulted in better 2-year functional outcomes for ≥50-year-old patients compared with a primary nonoperative treatment protocol. Delayed surgery in case of secondary displacement was not beneficial in terms of function.

OBJECTIVE: To determine whether treatment of isolated stable Weber B type ankle fractures with a cast or a simple orthotic device for three weeks produces non-inferior outcomes compared with conventional immobilisation in a cast for six weeks. DESIGN: Randomised, pragmatic, non-inferiority, clinical trial with blinded outcome assessment. SETTING: Two major trauma centres in Finland, 22 December 2012 to 6 June 2016. PARTICIPANTS: 247 skeletally mature patients aged 16 years or older with an isolated Weber B type fibula fracture and congruent ankle mortise in static ankle radiographs. INTERVENTIONS: Participants were randomly allocated to conventional six week cast immobilisation (n=84) or three week treatment either in a cast (n=83) or in a simple orthosis (n=80). MAIN OUTCOME MEASURES: The primary, non-inferiority, intention-to-treat outcome was the Olerud-Molander Ankle Score at 12 months (OMAS; range 0-100; higher scores indicate better outcomes and fewer symptoms). The predefined non-inferiority margin for the primary outcome was -8.8 points. Secondary outcomes were ankle function, pain, quality of life, ankle motion, and radiographic outcome. Follow-up assessments were performed at 6, 12, and 52 weeks. RESULTS: 212 of 247 randomised participants (86%) completed the study. At 52 weeks, the mean OMAS was 87.6 (SD 18.3) in the six week cast group, 91.7 (SD 12.9) in the three week cast group, and 89.8 (SD 18.4) in the three week orthosis group. The between group difference at 52 weeks for the three week cast versus six week cast was 3.6 points (95% confidence interval -1.9 to 9.1, P=0.20), and for the three week orthosis versus six week cast was 1.7 points (-4.0 to 7.3, P=0.56). In both comparisons, the confidence intervals did not include the predefined inferiority margin of -8.8 points. The only statistically significant between group differences observed in the secondary outcomes and harms in the two primary comparisons were slight improvement in ankle plantar flexion and incidence of deep vein thrombosis, both in the three week orthosis group versus six week cast group. CONCLUSION: Immobilisation for three weeks with a cast or orthosis was non-inferior to conventional cast immobilisation for six weeks in the treatment of an isolated stable Weber B type fracture. TRIAL REGISTRATION: ClinicalTrials.gov NCT01758835.

This study assessed risk factors for complications after volar plate fixation of distal radial fractures. An assessment of electronic patient records from 2008 to 2016 identified 867 patients with a total of 881 distal radial fractures who underwent volar plating in our hospital. A total of 132 complications after volar plate fixation of distal radial fractures were observed (complication rate 15%). Surgery performed by a low-volume surgeon and patient age less than 40 years were the most important risk factors for plate-related complications. In logistic regression analysis, operation performed by a low-volume surgeon and patient age less than 40 years were independent predictors of plate-related complications. Patient age less than 40 years and low-volume surgeon were also found to be independent risk factors for plate-related secondary operations. Surgical delay had no effect on the complication rate. Level of evidence: IV.

OBJECTIVES: To investigate the ability of individual surgeons [expert opinion (EO)] to predict distal radius fracture (DRF) healing above a threshold malalignment compared with the majority prediction of the group of surgeons ["majority rule," (MR)] and a statistically derived clinical prediction formula [Edinburgh wrist calculator (EWC)]. DESIGN: Comparative diagnostic study from prospectively collected data of consecutive patients. SETTING: Two academic level 1 and 1 academic level 2 trauma centers. PATIENTS/PARTICIPANTS: Eighteen surgeons assessed probability of healing above a threshold malalignment (often referred to as fracture "instability") for 71 fractures based on radiographs taken initially and after closed reduction and cast application. The probability of losing alignment according to the EWC was dichotomized (likely to lose alignment ≥0.5 vs. unlikely <0.5). MAIN OUTCOME MEASURES: Accuracy parameters of prediction of EO, MR, and EWC. RESULTS: EWC and MR demonstrated higher accuracy (0.77 and 0.75, respectively) and sensitivity (0.95 and 0.79, respectively) compared with EO (accuracy, 0.66 and sensitivity, 0.58) for predicting healing above the threshold malalignment. Reliability was higher for MR (kappa 0.88) than for EWC (kappa 0.63) or EO (kappa coefficient 0.44). The negative predictive value of the EWC for healing above a threshold of malalignment was excellent (0.97). CONCLUSIONS: Surgeon opinion is not reliable or accurate for predicting loss of alignment of a DRF above a threshold malalignment after closed reduction and immobilization. Dichotomized EWC may be a useful tool in predicting loss of alignment (instability) of a DRF. LEVEL OF EVIDENCE: Diagnostic Level II.

PURPOSE: This study investigated the long-term results of arthroscopic Bankart repair in terms of rates and timelines of recurrence of instability, with special interest in young adult patients aged ≤20 years. METHODS: Between 2000 and 2005, 186 shoulders [182 patients, 50 women, median age 26 (range 15-58) years] were operated on at a university hospital using arthroscopic Bankart repair because of instability after traumatic anteroinferior shoulder dislocation. Medical records were retrospectively reviewed and patients were assessed using postal questionnaires or telephone interview after a minimum of 10 years of follow-up [median 12.2 (range 10-16) years]. The primary outcome measure was recurrence of instability (assessed from 167 shoulders), other outcome measures included Oxford instability score (OIS), subjective shoulder value (SSV), and Western Ontario instability index (WOSI) (assessed from 157 shoulders). RESULTS: At the end of follow-up, 50/167 shoulders (30%) had recurrence of instability and 30/167 (18%) were subjected to reoperation due to instability symptoms. Twenty-six (52%) failures occurred within ≤2 years, 11 (22%) within 2-5 years, and 13 (26%) >5 years after surgery. Failure rate was 19/35 (54%) for patients aged ≤20 years and 31/132 (24%) for patients aged >20 years; reoperation rates were 11/35 (31%) and 19/132 (14%), respectively. Mean OIS was 20 (SD 9, range 12-50), SSV 83% (SD 21, range 10-100), and WOSI score 80 (SD 22, range 33-100). CONCLUSIONS: Nearly one-third of patients had recurrence of instability after arthroscopic Bankart repair after a minimum of 10-year follow-up. Patients aged ≤20 years did poorly with more than half of the patients having recurrence; alternative stabilization techniques should probably be considered for these patients. LEVEL OF EVIDENCE: IV.

BACKGROUND: The optimal treatment of isolated medial malleolar fractures is widely debated. The aim of this study is to analyse the different treatment methods. METHODS: The study included 137 patients with an isolated medial malleolar fracture treated at our hospital between 2000 and 2010. Functional outcome was assessed using Olerud-Molander score and health-related quality-of-life (HRQoL) was measured with RAND36 item health survey. Patients were sent follow-up questionnaires after an average of 9.5 years (4.3-15.2) from the date of treatment. RESULTS: The overall improvement in function was equivalent in both operative and non-operative treatment groups. However, the outcome scores declined in both groups as the primary displacement increased, regardless of the treatment method. HRQoL was similar in both groups. CONCLUSIONS: If maximal fracture displacement is ≤2mm, isolated medial malleolar fractures can be treated non-operatively with good outcome, but the operative treatment may also be performed without serious complications. The degree of fracture displacement is an independent risk factor for inferior functional result, regardless of the treatment method. LEVEL OF EVIDENCE: Therapeutic level of evidence: IV, retrospective cohort study.

BACKGROUND: In this prospective study, we used magnetic resonance imaging (MRI) to assess long-term Achilles tendon length, calf muscle volume, and muscle fatty degeneration after surgery for acute Achilles tendon rupture. METHODS: From 1998 to 2001, 60 patients at our center underwent surgery for acute Achilles tendon rupture followed by early functional postoperative rehabilitation. Fifty-five patients were reexamined after a minimum duration of follow-up of 13 years (mean, 14 years), and 52 of them were included in the present study. Outcome measures included Achilles tendon length, calf muscle volume, and fatty degeneration measured with MRI of both the affected and the uninjured leg. The isokinetic plantar flexion strength of both calves was measured and was correlated with the structural findings. RESULTS: The Achilles tendon was, on average, 12 mm (95% confidence interval [CI] = 8.6 to 15.6 mm; p < 0.001) longer (6% longer) in the affected leg than in the uninjured leg. The mean volumes of the soleus and medial and lateral gastrocnemius muscles were 63 cm (13%; p < 0.001), 30 cm (13%; p < 0.001), and 16 cm (11%; p < 0.001) lower in the affected leg than in the uninjured leg, whereas the mean volume of the flexor hallucis longus (FHL) was 5 cm (5%; p = 0.002) greater in the affected leg, indicating FHL compensatory hypertrophy. The median plantar flexion strength for the whole range of motion ranged from 12% to 18% less than that on the uninjured side. Finally, the side-to-side difference in Achilles tendon length correlated substantially with the strength deficit (ρ = 0.51, p < 0.001) and with medial gastrocnemius (ρ = 0.46, p = 0.001) and soleus (ρ = 0.42, p = 0.002) muscle atrophy. CONCLUSIONS: Increased Achilles tendon length is associated with smaller calf muscle volumes and persistent plantar flexion strength deficits after surgical repair of Achilles tendon rupture. Strength deficits and muscle volume deficits are partly compensated for by FHL hypertrophy, but 11% to 13% deficits in soleus and gastrocnemius muscle volumes and 12% to 18% deficits in plantar flexion strength persist even after long-term follow-up.

BACKGROUND: Discovery Elbow System (DES) is a semi-constrained prosthesis, mainly used for patients with rheumatoid arthritis (RA). METHODS: Records from 79 patients with RA (90 DES arthroplasties) were reviewed; 47 patients with 55 DES elbows were re-examined. Range of motion (ROM) of both elbows, upper limb function, and quality of life (Disabilities of the Arm, Shoulder, and Hand [DASH] score, Mayo Elbow Performance Score [MEPS], and the RAND 36-Item Health Survey [RAND-36]) were assessed. Cementing quality was assessed, and radiolucent lines measured from plain radiographs. Mean follow-up was 64 (range 24-123) months. RESULTS: Pre-operatively to post-operatively, mean elbow flexion improved from 120° to 146° (p < 0.001) and mean extension lag improved from 29° to 24° (p = 0.02), respectively. At follow-up, mean supination was 66°, mean pronation was 69°, and mean grip strength was 14 kg. Grip strength and ROM (except supination) were similar between the DES elbow and contralateral un-operated elbow. Mean post-operative MEPS was 93 points (excellent, n = 38; good, n = 14; fair, n = 2; and poor, n = 1). Mean DASH score was 43 points. The RAND-36 showed that physical functioning, physical role functioning, bodily pain, and general health were lower than the Finnish reference values. Primary cementing was challenging, and radiolucent lines appeared during follow-up. Four prostheses were revised because of aseptic loosening (n = 3) and periprosthetic fracture (n = 1). CONCLUSION: DES provides significant improvement in patient's flexion-extension arc. Cementing of the elbow prosthesis was challenging; radiolucent lines appeared during the 5-year follow-up, but their clinical relevance remains unclear. First-generation locking screws may loosen over time. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: This study aimed to identify factors from standard radiographs that contributed to the stability of the ankle mortise in patients with isolated supination-external rotation fractures of the lateral malleolus (OTA/AO 44-B). METHODS: Non-stress radiographs of the mortise and lateral views, without medial clear space widening or incongruity, were prospectively collected for 286 consecutive patients (mean age, 45 years [range, 16 to 85 years]), including 144 female patients (mean age, 50 years [range, 17 to 85 years]) and 142 male patients (mean age, 40 years [range, 16 to 84 years]) from 2 trauma centers. The radiographs were analyzed for fracture morphology by 2 orthopaedic surgeons, who were blinded to each other's measurements and to the results of external rotation stress radiographs (the reference for stability). Factors significantly associated with ankle mortise stability were tested in multiple logistic regression. Receiver operating characteristic analyses were performed for continuous variables to determine optimal thresholds. A sensitivity of >90% was used as the criterion for an optimal threshold. RESULTS: According to external rotation stress radiographs, 217 patients (75.9%) had a stable injury, defined as that with a medial clear space of <5 mm. Independent factors that predicted stable ankle mortise were female sex (odds ratio [OR], 2.5 [95% confidence interval (CI), 1.4 to 4.6]), a posterior diastasis of <2 mm (corresponding with a sensitivity of 0.94 and specificity of 0.39) on lateral radiographs (OR, 10.8 [95% CI, 3.7 to 31.5]), and only 2 fracture fragments (OR, 7.3 [95% CI, 2.1 to 26.3]). When the posterior diastasis was <2 mm and only 2 fracture fragments were present, the probability of a stable ankle mortise was 0.98 for 48 female patients (16.8%) and 0.94 for 37 male patients (12.9%). CONCLUSIONS: Patients with noncomminuted lateral malleolar fractures (85 patients [29.7%]) could be diagnosed with a stable ankle mortise without further stress testing, when the fracture line widths were <2 mm on lateral radiographs. LEVEL OF EVIDENCE: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: It remains controversial whether nonsurgical or surgical treatment provides better calf muscle strength recovery after an acute Achilles tendon rupture (ATR). Recent evidence has suggested that surgery might surpass nonsurgical treatment in restoring strength after an ATR. PURPOSE: To assess whether magnetic resonance imaging (MRI) findings could explain calf muscle strength deficits and the difference between nonsurgical and surgical treatments in restoring calf muscle strength. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: From 2009 to 2013, 60 patients with acute ATRs were randomized to surgery or nonsurgical treatment with an identical rehabilitation protocol. The primary outcome measure was the volume of calf muscles assessed using MRI at 3 and 18 months. The secondary outcome measures included fatty degeneration of the calf muscles and length of the affected Achilles tendon. Additionally, isokinetic plantarflexion strength was measured in both legs. RESULTS: At 3 months, the study groups showed no differences in muscle volumes or fatty degeneration. However, at 18 months, the mean differences between affected and healthy soleus muscle volumes were 83.2 cm3 (17.7%) after surgery and 115.5 cm3 (24.8%) after nonsurgical treatment (difference between means, 33.1 cm3; 95% CI, 1.3-65.0; P = .042). The study groups were not substantially different in the volumes or fatty degeneration of other muscles. From 3 to 18 months, compensatory hypertrophy was detected in the flexor hallucis longus (FHL) and deep flexors in both groups. In the nonsurgical treatment group, the mean difference between affected and healthy FHL muscle volumes was -9.3 cm3 (12%) and in the surgical treatment group was -8.4 cm3 (10%) ( P ≤ .001). At 18 months, Achilles tendons were, on average, 19 mm longer in patients treated nonsurgically compared with patients treated surgically ( P < .001). At 18 months, surgically treated patients demonstrated 10% to 18% greater strength results ( P = .037). Calf muscle isokinetic strength deficits for the entire range of ankle motion correlated with soleus atrophy (ρ = 0.449-0.611; P < .001). CONCLUSION: Treating ATRs nonsurgically with a functional rehabilitation protocol resulted in greater soleus muscle atrophy compared with surgical treatment. The mean Achilles tendon length was 19 mm longer after nonsurgical treatment than after the surgical treatment of ATRs. These structural changes partly explained the 10% to 18% greater calf muscle strength observed in patients treated with surgery compared with those treated nonsurgically.
