RESUMO
INTRODUCTION: Osteosynthesis of femoral neck fractures (FNFs) is an important treatment option, especially for younger patients. We aimed to assess the rate of early implant-related complications in FNF osteosynthesis using the Femoral Neck System (FNS). PATIENTS AND METHODS: Consecutive patients diagnosed with displaced or nondisplaced FNFs were treated with FNS in this prospective, observational, multicenter investigation. Patients were followed up for minimally 3 months and up to 12 months if radiologic bone union and no pain was not achieved beforehand. Predefined treatment-related adverse events (AEs, defined as implant failure, loss of reduction, iatrogenic fractures, deep infection, and surgical revision), radiologic bone union, and patient-reported Harris hip score (HHS) and EQ-5D-5L index score were assessed. RESULTS: One hundred and twenty-five patients were included in the study. Thirty-eight (30.4%) fractures were displaced (Garden III and IV), and 37 (29.6%) were vertical fractures (Pauwels type III). Predefined treatment-related AE rate at 3 months was 8 patients, 6.4% (95% CI, 2.8-12.2), and at 12 months, 11 patients, 8.8% (95% CI, 4.5-15.2). Cumulative incidences of bone union were 68% at 3 months, 90% at 6 months, and 98% at 12 months. The mean changes of HHS and EQ-5D-5L index score between preinjury and at 12 months were -7.5 (95% CI, [ - 21.1] to [6.2]) and - 0.03 (95% CI, [ - 0.21] to [0.15]), respectively; neither were statistically significant. CONCLUSION: The current study on osteosynthesis of FNFs with the FNS resulted in treatment-related complication rates of 6.4% (95% CI, 2.8-12.2) at 3 months and 8.8% (95% CI, 4.5-15.2) at 12 months. On average, patients returned to preinjury function and quality of life. The current study may also indicate that the conventional wisdom of treating stable FNF in patients aged between 60 and 80 years with osteosynthesis may need to be reconsidered. REGISTRATION: The study is registered with ClinicalTrials.gov (registration number: NCT02422355).

BACKGROUND: The Trauma Expectation Factor Trauma Outcomes Measure (TEFTOM) questionnaire is a self-administered, patient-rated outcome measurement questionnaire designed to measure both 'expectation' and 'outcome' in orthopaedic trauma patients using two subsets of 10 items. We aimed to validate this instrument in a culturally diverse cohort of patients recruited from Asian and European regions. METHODS: A total of 193 adult patients with surgically treated AO Foundation/Orthopaedic Trauma Association types 43 and 44 ankle malleolar and distal tibia fractures were recruited with 158 followed up till 1 year. Expectations were assessed prior to surgery, at 2 weeks and after 6 months using the trauma expectation factor (TEF) score. Outcomes were evaluated at 2 weeks, 6 and 12 months using the trauma outcome measure (TOM), American Academy of Orthopaedic Surgeons (AAOS), foot and ankle outcome score (FAOS) and short form-36 (SF-36) questionnaires. Psychometric properties of TEFTOM were assessed. RESULTS: TEF and TOM demonstrated good internal consistency (Cronbach's α > 0.87) and reliability at all time points (intra-class correlation coefficients > 0.90). TOM showed strong correlations (R2 ≥ 0.60) with the AAOS foot and ankle score, all FAOS subscales, except 'symptoms' and SF-36 physical functioning, role physical, bodily pain, social functioning and the physical component summary at 6 and 12 months. Effect sizes for TOM were 2.30 and 0.74 from 2 weeks to 6 months and from 6 months to 12 months, respectively. The baseline patient TEF was predictive for the 1-year TOM score. CONCLUSIONS: TEFTOM demonstrated good psychometric properties in this cohort of patients with ankle fractures. The TEF 'expectation' score was predictive of the TOM 'outcome' score. We recommend researchers and clinicians to utilize TEFTOM when patient expectation measurement is concerned for orthopaedic trauma patients.

INTRODUCTION: Cement augmentation of the proximal humerus internal locking system (PHILOS) screws might reduce complication rates in osteoporotic bones. This study compared the risk of mechanical failure during the first year after PHILOS™ treatment of proximal humerus fractures (PHF) without (control group) and with (augmented group) screw augmentation. Secondary objectives were to report shoulder functions, quality of life (QoL), adverse events (AEs), and reoperation rates. MATERIALS AND METHODS: This multicenter randomized trial enrolled patients aged ≥ 65 years with displaced/unstable PHF from eight European centers. Randomization was performed during surgery through sealed opaque envelopes. Mechanical failures were assessed by two independent reviewers via radiographs, shoulder function by Quick DASH, SPADI, and Constant Murley scores, and QoL by EQ-5D. Follow-ups were planned at postoperative 6 weeks, 3, 6, and 12 months. RESULTS: The preliminary analysis of 6-week radiographs of the first 59 enrolled patients suggested a mechanical failure rate lower than expected and the difference between groups was too small to be detected by the planned sample size of 144. The trial was prematurely terminated after 67 patients had been enrolled: 34 (27 eligible) in the control group and 33 (29 eligible) in the augmented group. Follow-ups were performed as planned. Nine patients had mechanical failures and the failure rates (95% CI) were: augmented group, 16.1% (5.5; 33.7); control group, 14.8% (4.2; 33.7); the relative risk (95% CI) for the augmented group was 1.09 (0.32; 3.65) compared to the control group (p = 1.000). No statistically significant differences in shoulder function, QoL, and AEs were observed between study groups at 1 year. Nine patients (15.8%) underwent a revision. CONCLUSIONS: Due to premature termination, the study was underpowered. A larger study will be necessary to determine if cement augmentation lowers the risk of mechanical failure rate.

This study investigated the effectiveness and the outcomes of rivaroxaban vs the standard of care for venous thromboembolic prophylaxis in patients undergoing fracture-related surgery. A total of 413 patients undergoing fracture-related surgery from 9 Swiss orthopedic and trauma centers were enrolled. The authors selected the type of venous thromboembolic prophylaxis according to standardized medical practice at the participating centers before the inclusion of patients: 208 patients received rivaroxaban and 205 received the standard of care. Data on symptomatic thromboembolic and bleeding events, surgery-related complications, death, adverse events, time to mobilization, and hospital discharge were collected. Symptomatic thromboembolic events were reported in 1 patient (0.5%) and 2 patients (1.0%) and treatment-emergent major bleeding events were reported in 1 patient (0.5%) and 2 patients (1.0%) receiving rivaroxaban and the standard of care, respectively. The durations of hospital stay and venous thromboembolic prophylaxis were similar in the 2 groups. In both groups, adverse events related to venous thromboembolic prophylaxis were reported in 12 patients. The proportion of patients with minor and major fracture surgery was 74.3% and 25.7%, respectively. In patients undergoing minor fracture surgery receiving rivaroxaban (n=167) and the standard of care (n=140), no symptomatic thromboembolic events and no major bleeding events were reported. Outcomes of this study indicate that rivaroxaban might be an appropriate oral alternative for venous thromboembolic prophylaxis in routine medical care after fracture-related major and minor surgery. Reported results were comparable to those from other large-scale, noninterventional and randomized controlled studies. [Orthopedics. 2017; 40(2):109-116.].

INTRODUCTION: The Lower Extremity Measure (LEM) was developed to provide a specific instrument to detect changes in physical function in patients with hip fracture. Of 29 questions, 3 have a valid "not applicable" answer option. The goal of this study was to validate the LEM in German and to determine the added value to the physical functioning (pf) subscale of the Short Form 36 (SF-36). MATERIALS AND METHODS: The LEM was translated according to published guidelines and administered to patients with hip fracture (31 A1-A3 and 31 B1-B3) shortly after surgery (baseline), at 3 months (3M), and for reliability testing at 3 months plus 1 week (3M+). The reproducibility, internal consistency, floor and ceiling effects, construct validity, and responsiveness of the German LEM were assessed. RESULTS: A total of 106 patients completed the LEM and SF-36 (mean age 75.5; 67% women) at baseline (mean of 4.9 days after operation), and 88 completed both questionnaires at both the 3M and 3M+ assessments. At each assessment time point, between 6% and 23% of the patients answered 7 questions as "not applicable." Reproducibility and internal consistency were high (intraclass correlation coefficient = 0.93; Cronbach's α = .96). No floor effect (0%) and a minor ceiling effect (7.87%) were found for the total LEM score. The strongest correlation was found between the LEM and the SF-36 subscale pf (Spearman ρ = .93). Responsiveness was similar for the SF-36 pf subscale and the LEM when using effect size (SF-36 pf 0.71 vs LEM 0.72) and better for the LEM when using standardized response mean (SF-36 pf 0.65 vs LEM 0.76). DISCUSSION: The German LEM is a reliable, valid, and responsive measure for the self-assessment of patients after hip fracture surgery. As a number of questions are not applicable to elderly patients, the added value of this lengthy questionnaire in these often frail, sometimes cognitively impaired patients is still open for debate.
RESUMO
PURPOSE: To prospectively assess arthroscopic repair of massive cuff tears (MCT) in a highly selective patient group with large subscapularis (SSC) tendon tears by means of clinical results and magnetic resonance imaging (MRI) studies. METHODS: Between April 2009 and December 2010, 26 patients with MCT were treated with arthroscopic rotator cuff repair. Only lesions involving a large tear of the SSC tendon (Lafosse III or IV) in combination with a complete tear of the supraspinatus (SSP) tendon and a tear of at least the anterior third of the infraspinatus (ISP) tendon were included. Minimum follow-up was 1 year. Pre- and postoperative assessment included a standardized clinical examination, subjective patient outcome, and MRI (structural integrity, fatty muscle infiltration, and muscular mass). RESULTS: Mean follow-up was 17 months (range, 12 to 34 months). MRI was performed in 25 patients. In 21 (84%) the cuff repair was intact. A partial retear of the SSC was found in 2 patients (8%). In 2 patients (8%) a full-thickness retear of the posterosuperior cuff was observed (1 SSP, 1 SSP/ISP). A significant increase of the muscle mass and decrease of fatty infiltration was observed for the SSC and SSP but not for the ISP. The mean Constant-Murley score improved from 36 to 86 points (P < .001) with all its subscores as well (P < .001). Muscular strength improved for the SSC (4.9 v 3.0, P < .001), SSP (4.6 v 2.9, P < .001), and ISP (4.8 v 3.4, P < .001). Overall patient satisfaction was high (3.6 ± 0.8). CONCLUSIONS: Arthroscopic repair of MCT involving the ISP, SSP, and large tears of the SSC provides a reliable tendon healing, in particular for the SSC tendon, combined with good functional results. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

This study assessed whether mechanically measured trabecular bone strength is an independent predictor of dynamic hip screw (DHS) stability, i.e., DHS migration (DHSM) after the fixation of proximal femoral fractures. One-hundred and seven patients older than 50 years with proximal femoral fractures were included. During fracture fixation, a mechanical probe (DensiProbe™ Hip) was inserted at the site where the DHS tip would ultimately be positioned. Peak torque to breakaway the trabecular bone was measured. Fracture reduction, primary implant position and postoperative DHSM were assessed by radiographs taken postoperatively, at 6 and 12 weeks after surgery. Univariate regression analysis revealed no association between peak torque and DHSM (R(2) = 0.025, p = 0.135). DHSM correlated with the primary DHS position, i.e., the distance between the DHS and (i) the central femoral neck axis (CNFAD, R(2) = 0.230; p < 0.0001) and (ii) the apex of the femoral head (R(2) = 0.110; p = 0.001). DHSM did not correlate with areal BMD of the contralateral proximal femur. Multivariable regression modeling revealed the CFNAD as predictive factor for screw migration. The primary implant position measured by the CFNAD, rather than DensiProbe™ Hip measured bone strength, is an independent predictor of DHSM.

OBJECTIVES: Shoulder disorders have an important impact on a patient's capacity to work. We investigated whether there is a relationship between subjective or objective outcome measures and the ability and time for returning to work (RTW) after a proximal humerus fracture (PHF). DESIGN: Retrospective single-centre study from March 2003 to June 2008. SETTING: City hospital, trauma level one centre. INTERVENTION: All PHF stabilized with a PHILOS(®). MAIN OUTCOME MEASUREMENTS: Routine follow-up examinations (X-ray, Constant-Murley Score (CMS), Short-Form 36 (SF-36)) were performed prospectively after 1.5, 3, 6 and 12 months or until RTW. Primary interest was the comparison of the outcome scores with the time needed for RTW. RESULTS: 72 patients (52 years (22-64), 37 (51%) women) fulfilled the inclusion criteria. We distinguished "office-workers" (OW) (n = 49, 68%) from patients who worked at a physically demanding job (PW) (n = 23, 32%). Although time for RTW was fundamentally different (42 (OW) vs 118 days (PW), p<0.001), CMS (64.7 vs 64.1) and SF-36 (66.8 vs 69.9) at time of RTW were almost identical. At follow-up, CMS and SF-36 were always lower in the PW group. CONCLUSION: Jobs which require higher physical demands were likely to influence and to delay RTW. This study identifies cut off values for CMS and SF-36 at which a patient feels capable or willing to RTW after PHF. These values show the importance and impact of a patient's occupation or demands on RTW. We were able to show, that besides age, sex and fracture, the type of occupation might alter the scores in postoperative outcomes.
RESUMO
BACKGROUND: There is biomechanical evidence that bone density predicts the mechanical failure of implants. The aim of this prospective study was to evaluate the influence of local bone mineral density on the rate of mechanical failure after locking plate fixation of proximal humeral fractures. METHODS: We enrolled 150 patients who were from fifty to ninety years old with a closed, displaced proximal humeral fracture fixed with use of a locking plate from July 2007 to April 2010. There were 118 women and thirty-two men who had a mean age of sixty-nine years. Preoperative computed tomography (CT) scans were done to assess bone mineral density of the contralateral humerus, and dual x-ray absorptiometry of the distal end of the radius of the unaffected arm was conducted within the first six weeks postoperatively. At follow-up evaluations at six weeks, three months, and one year postoperatively, pain, shoulder mobility, strength, and multiple functional and quality-of-life outcome measures (Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire; Shoulder Pain and Disability Index [SPADI]; Constant score; and EuroQuol-5D [EQ-5D]) were done and standard radiographs were made. We defined mechanical failure as all complications related to bone quality experienced within one year. RESULTS: After locking plate fixation, fifty-three (35%) of 150 patients had mechanical failure; loss of reduction and secondary screw loosening with perforation were common. CT assessments of local bone mineral density showed no difference between patients with and without mechanical failure (89.82 versus 91.51 mg/cm3, respectively; p = 0.670). One-year DASH, SPADI, and Constant scores were significantly better for patients without mechanical failure (p ≤ 0.05). CONCLUSIONS: We did not find evidence of an association between bone mineral density and the rate of mechanical failures, which may suggest that patients with normal bone mineral density are less prone to sustain a proximal humeral fracture. Future studies should target other discriminating factors between patients with and without mechanical failure. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

PURPOSE: The purpose of this study was to prospectively assess the efficacy of arthroscopic repair of isolated high-grade subscapularis (SSC) tendon lesions by means of clinical follow-up combined with magnetic resonance imaging investigations. METHODS: Between January 2008 and September 2010, 11 patients (9 men and 2 women; mean age, 45 ± 10 years) with Lafosse type III or IV traumatic isolated SSC tendon lesions underwent arthroscopic repair including tenodesis of the long head of the biceps tendon. All patients were preoperatively assessed by clinical examination (Constant-Murley score [CMS]) and contrast-enhanced magnetic resonance arthrography. At 1 year of follow-up, specific clinical SSC tests, the CMS, and the loss of external rotation were evaluated. A native magnetic resonance investigation was performed to assess the structural integrity of the repair. The SSC muscle was compared with its preoperative condition regarding fatty infiltration and size (cross-sectional area). Patient satisfaction was graded from 1 (poor) to 4 (excellent). RESULTS: The mean time interval from trauma to surgery was 3.7 months. A concomitant lesion of the biceps tendon was observed in 10 patients (91%). The mean CMS improved from 44 to 89 points (P < .001). The functional tests showed a significant increase in strength (P < .05) (belly-press test, 4.8 v 2.9; lift-off test, 4.8 v 2.9). The mean loss of external rotation at 0° of abduction was 10° compared with the contralateral side (P < .05). Patient satisfaction was high. Magnetic resonance imaging evaluation showed complete structural integrity of the tendon repair in all studies. The SSC showed a significant decrease in fatty infiltration and increase in the cross-sectional area. CONCLUSIONS: Arthroscopic repair of higher-grade isolated SSC lesions provides reliable tendon healing accompanied by excellent functional results 1 year after surgery. LEVEL OF EVIDENCE: Level IV, prospective therapeutic case series.

OBJECTIVE: Most clinical evaluations after fracture treatment focus on pure functional and radiological outcome. However, this may not appreciate the impact on quality of life (QoL). The aim of this study was to assess QoL and its improvement during the first year of postoperative recovery after fracture treatment. DESIGN: Prospective single-centre observational study. SETTING: Trauma unit. City hospital. PATIENTS: From March 2003 to June 2008 inclusion of 269 consecutive patients (72 years, 77% female) was possible. All were treated by open reduction and internal fixation (ORIF) with PHILOS because of isolated traumatic fractures of the proximal humerus. INTERVENTION: Clinical follow-up examinations were performed at 6 weeks and 3, 6, and 12 months, postoperatively. MAIN OUTCOME MEASUREMENTS: Constant-Murley score (CMS) and the QoL (SF-36 questionnaire) were used to assess outcome. All results were stratified according to length of follow-up, age, and fracture type. RESULTS: CMS and SF-36, including the corresponding subgroups Physical Component Summary and Mental Component Summary, demonstrated continuing improvement during the period of observation. US norm values for the SF-36 were achieved after 6 months. However, speed of progress varied greatly between the scores and age groups. The fracture type significantly impacted CMS. Increasing age and complexity of fracture influenced the results negatively and cumulatively. CONCLUSION: This study highlights and defines subjective improvements and changes of QoL up to 1 year after ORIF of these fractures. Increasing age and a more complex fracture type is correlated with a deceleration of functional improvement. The CMS shows a definite positive correlation with the unassisted self-evaluation of SF-36, but exchangeability could not be demonstrated.

BACKGROUND: Since 2003, we have used the Proximal Humerus Interlocking System plate for treatment of proximal humeral fractures. Although many patients have good and excellent results, the reported rate of complications varies. We have focused on the complication rate and risk factors for complications 1 year after surgery. METHODS: From 2003 until 2008, a total of 294 (223 women; 71 men; median age, 72.9) patients were included. General data were collected at the time of injury (Charlson Index, smoking, and steroid therapy). Fractures were classified (AO/OTA) retrospectively. The follow-up of 1 year included radiographs and Constant-Murley score for functionality. Complications and revision surgeries were analyzed specifically. RESULTS: We found 83 (28.2%) patients with a total of 105 complications, requiring a total of 72 (24.5%) revision surgeries. The most frequent complication was screw cutout (33 of 294, 11.2%), because of secondary fracture displacement or avascular necrosis (AVN). AVN (20 of 294, 6.8%) was the main reason for secondary arthroplasty. Smoking more than 20 pack years had a significant impact on the complication rate. Fractures classified 11-A3 showed more implant failures. Fracture dislocations predisposed to secondary screw cutout and AVN. Patients without complications (211, 71.8%) achieved a median Constant-Murley score of 89 (40-100) points. CONCLUSION: This study points out several predisposing factors for negative outcome after open reduction and internal fixation with the Proximal Humerus Interlocking System plate (fracture type: 11-A3, fracture dislocations, and smoking). Accounting for these, patient's risk for complications can be evaluated more individually and taken into consideration for the concept of treatment. Altering the surgical technique was associated with a significant reduction in the incidence of secondary screw cutout.

BACKGROUND: Neer Group VI proximal humeral fractures often are related to persistent disability despite surgical treatment. We retrospectively compared the outcome after open reduction and internal fixation with the PHILOS(®) plate or primary hemiarthroplasty in patients with Neer Group VI fractures focusing on complications, shoulder function, health-related quality of life (SF-36), and potential risk factors for complications. QUESTIONS/PURPOSES: The aim of this study was to compare the PHILOS(®) plate with primary hemiarthroplasty for treatment of specific Neer Group VI fractures. We asked whether (1) both procedures have comparable clinical and radiologic complication rates; (2) one procedure is superior in terms of revision rate; (3) objective and subjective shoulder function (Constant-Murley score) and health-related quality of life (SF-36) were comparable in both groups at final followup; and (4) there are clinical or radiologic predictors for complications in any group? METHODS: Between 2002 and 2007, 44 consecutive patients (mean, 75.2 years) with a Neer Group VI proximal humeral fracture were included. Twenty-two patients treated with a PHILOS(®) plate were compared with 22 patients treated by primary hemiarthroplasty. Both groups were similar in all criteria. At minimum followup of 12 months (mean, 30 months; range, 12-83 months), radiographic control, Constant-Murley score, and SF-36 were performed. RESULTS: Fourteen patients with complications (63.6%) were counted in the PHILOS(®) plate group, of which 10 (45.4%) needed revision surgery, mostly as a result of avascular necrosis and screw cut-outs. In the primary hemiarthroplasty group, only one patient needed revision surgery (4.5%). Smoking and steroid therapy were substantially associated with complications in the PHILOS(®) plate group. There were no differences between the two groups regarding Constant-Murley or SF-36 scores. CONCLUSIONS: Angular stable open reduction and internal fixation was associated with high complication and revision rates, especially in patients who smoked and those receiving steroid therapy. Primary hemiarthroplasty provides limited function, which had little influence on the quality of life in this elderly collective. There are predictive factors for complications after the treatment of Neer Group VI proximal humeral fractures with the PHILOS(®) plate. Primary hemiarthroplasty remains a good option, especially when treating elderly patients.

BACKGROUND: Advances in diagnostic imaging and the introduction of damage control strategy in trauma have influenced our approach to treating liver trauma patients. The objective of the present study was to investigate the impact of change in liver trauma management on outcome. METHODS: A total of 468 consecutive patients with liver trauma treated between 1986 and 2010 at a single level 1 trauma center were reviewed. Mechanisms of injury, diagnostic imaging, hepatic and associated injuries, management (operative [OM] vs. nonoperative [NOM]), and outcome were evaluated. The main outcome analysis compared mortality for the early study period (1986-1996) versus the later study period (1997-2010). RESULTS: 395 patients (84%) presented with blunt liver trauma and 73 (16%) with penetrating liver trauma. Of these, 233 patients were treated with OM (50%) versus 235 with NOM (50%). The mortality rate was 33% for the early period and 20% for the later period (odds ratio 0.19; 95% CI 0.07-0.50, P = 0.001). A significantly increased use of computed tomography (CT) as the initial diagnostic modality was observed in the late period, which almost completely replaced peritoneal lavage and ultrasound. There was a significant shift to NOM in the later period (early 15%, late 63%) with a low conversion rate to OM of 4.2%. Age, degree of hepatic and head injury, injury severity, intubation at admission, and early period were independent predictors of mortality in the multivariate analysis. CONCLUSIONS: Integration of CT in early trauma-room management and shift to NOM in hemodynamically stable patients resulted in improved survival and should be the gold standard management for liver trauma.

BACKGROUND: To evaluate functional, radiologic, and subjective outcome after volar locking plate osteosynthesis (VLPO) for unstable distal radius fractures (DRF). METHODS: In this study, patients treated with VLPO for isolated DRF between March 2005 and December 2007 were prospectively evaluated. Patients with multiple injuries or those unavailable for follow-up were excluded from further evaluation. Range of motion, grip strength, and the subjective Patient-Rated Wrist Evaluation score were monitored for 6 weeks, 3 months, 6 months, and finally 1 year after surgery. The uninjured contralateral wrist served as control. The radiologic outcome after 1 year was scored using the Lidstrom score. RESULTS: In total, 245 patients were included in the study with a mean age of 62 years ± 18 years. At the final follow-up, 1 year after surgery, 228 patients (93%) could be controlled. Range of motion significantly increased during follow-up. One year after surgery, mean flexion was 64° ± 15°, and mean extension reached 64 ° ± 15 ° corresponding with >90% of the uninjured contralateral wrist function. Grip strength increased from 14 kg ± 8 kg (54%) 6 weeks after surgery to 25 kg ± 11 kg (91%) at the final follow-up. Patient-Rated Wrist Evaluation score resulted in mean 8 points ± 16 points after 1 year. Lidstrom score reached a mean of 1.3 points ± 0.6 points, demonstrating a good initial fracture reduction and stable fixation. A complication rate of 15% could be seen in our series, among secondary fracture displacement in two patients (1%). CONCLUSIONS: VLPO for the treatment of unstable DRF is a reliable technique with excellent subjective, objective, and radiologic outcome.

Minimal invasive plate osteosynthesis (MIPO) not only meets the criteria of a "biological" osteosynthesis by minimising invasivity as well as iatrogenic soft tissue damage, but can also provide adequate stability for fracture healing and early functional aftertreatment. Up to date, only few publications report on MIPO of humeral shaft fractures mainly using the anterolateral deltopectoral approach for proximal plate insertion. Objective of the present study was to assess the feasibility and clinical outcome of MIPO for metadiaphyseal fractures of the proximal humerus through a lateral approach using angular stable long PHILOS(®)-plates. We retrospectively evaluated 29 patients (mean age 77 years, range 48-95 years) with displaced metadiaphyseal fractures of the proximal humerus treated with MIPO technique. For the first time, an angular stable long PHILOS(®)-plate through a lateral deltoid-split approach proximally and a brachialis/brachioradialis intermuscular approach with exposure of the radial nerve distally, were used. There were no infections and no iatrogenic injuries to the axillary and radial nerve. One patient showed subacromial impingement and one patient had to be reoperated for redislocation of the distal fragment with screw breakage, which was most likely due to incorrect screw placement. This patient was successfully operated using the same method and implant. Besides one patient who refused further follow-up, 28 patients could be followed up to a mean of 8 months (range 3-12 months) each with an entirely healed fracture. Furthermore, patient's quality of life was documented using the SF-36 questionnaire. Comparison with published United States normative data showed no significant deficits in the physical as well as in the mental domains 8 months after MIPO. Minimal invasive long PHILOS(®)-plate osteosynthesis using a combined lateral deltoid-split and brachialis/brachioradialis intermuscular approach proved to be a safe procedure for the treatment of metadiaphyseal fractures of the proximal humerus with low morbidity and full restoration of quality of life in these elderly patients.

BACKGROUND: Care of elderly patients after hip fracture is not well established. METHODS: We enrolled 173 patients with acute hip fracture who were 65 years or older (79.2% women; mean age, 84 years; 77.4% living at home). Using a factorial design, we randomly allocated patients to extended physiotherapy (PT) (supervised 60 min/d during acute care plus an unsupervised home program) vs standard PT (supervised 30 min/d during acute care plus no home program; single-blinded), and to cholecalciferol therapy, 2000 vs 800 IU/d (double-blinded). Primary outcome was rate of falls; secondary outcome was rate of hospital readmissions during the 12-month follow-up. All analyses included 173 individuals and used multivariate Poisson regression analyses. RESULTS: At baseline, 50.9% of participants had 25-hydroxyvitamin D levels of less than 12 ng/mL and 97.7% of less than 30 ng/mL. We documented 212 falls and 74 hospital readmissions. Because this was a factorial design trial, all analyses tested the main effect of each treatment while controlling for the other in 173 participants. Extended vs standard PT reduced the rate of falls by 25% (95% confidence interval [CI], -44% to -1%). Cholecalciferol treatment, 2000 vs 800 IU/d, did not reduce falls (28%; 95% CI, -4% to 68%), but reduced the rate of hospital readmissions by 39% (95% CI, -62% to -1%). CONCLUSIONS: Extended PT was successful in reducing falls but not hospital readmissions, whereas cholecalciferol treatment, 2000 IU/d, was successful in reducing hospital readmission but not falls. Thus, the 2 strategies may be useful together because they address 2 different and important complications after hip fracture.

BACKGROUND: Stable anatomical reconstruction of the joint surface in ankle fractures is essential to successful recovery. However, the functional outcome of fractures involving the posterior tibial plafond is often poor. We describe the morbidity and functional outcome for plate fixation of the displaced posterior malleolus using a posterolateral approach. MATERIALS AND METHODS: The posterolateral approach was used for osteosynthesis of the posterior malleolus in 45 consecutive patients (median age 54 years) with AO/Muller-classification type 44-A3 (n = 1), 44-B3 (n = 35), 44-C1 (n = 7), and 44-C2 (n = 2) ankle fractures. Thirty-three of the patients suffered complete fracture dislocation. Functional outcome at followup was measured using the modified Weber protocol and the standardized AAOS foot and ankle questionnaire. Radiological evaluation employed standardized anterior-posterior and lateral views. RESULTS: The fragment comprised a median of 24% (range, 10% to 48%) of the articular surface. Postoperative soft tissue problems were encountered in five patients (11%), one of whom required revision surgery. Two patients (4%) developed Stage I complex regional pain syndrome. Clinical and radiological followup at 25 months disclosed no secondary displacement of the fixed fragment. The median foot and ankle score was 93 (range, 58 to 100), shoe comfort score was 77 (range, 0 to 100). A median score of 7 (range, 5 to 16) was documented using the modified Weber protocol. CONCLUSION: The posterolateral approach allowed good exposure and stable fixation of a displaced posterior malleolar fragment with few local complications. The anatomical repositioning and stable fixation led to good functional and subjective outcome.

PURPOSE: To determine whether a volar radial (Henry) exposure to the distal radius is associated with less median nerve dysfunction than a direct volar exposure of the distal radius through the carpal tunnel that has been abandoned due to median nerve problems. METHODS: Over an 18-month period, all patients with distal radius fractures treated with volar locking plate osteosynthesis were consecutively integrated into this therapeutic study. A direct volar midline approach ulnar to the flexor tendons and median nerve including prophylactic carpal tunnel release (CTR) was routinely performed from July 2003 to December 2004 (CTR group). Due to median nerve problems, this approach was abandoned and a distal part of the classical Henry approach (HRY) through the flexor carpi radialis (FCR) tendon sheath was performed for volar locking plate osteosynthesis in a second period from April 2005 to May 2006 (HRY group). In this group, the carpal tunnel was released only in selected cases. Data were collected prospectively for both groups. Analysis included clinical examination, the Patient-Rated Wrist Evaluation, and radiological follow-up up to 1 year after surgery. RESULTS: Eighty-three patients entered the CTR group during the initial series. Thirty-one patients showed median nerve dysfunction 6 weeks after surgery. In the second period of observation, 91 patients entered the HRY group. The carpal tunnel was therapeutically decompressed in 18 patients, leaving the carpal tunnel untouched in 91 patients. Temporary median nerve paraesthesia was seen in 4 patients without CTR in the HRY group 6 weeks after surgery. After 1 year, persistent median nerve irritation was observed in 4 patients of the CTR group and none of the HRY group. Grip strength, range of motion, and Patient-Rated Wrist Evaluation were similar after 1 year. CONCLUSIONS: The direct volar approach to the distal radius with routine CTR should be abandoned because it was associated with an increased rate of temporary and persistent median nerve irritation compared to the distal part of the classic Henry approach in our series. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.
