Early functional improvements using continuous passive motion therapy after angular-stable plate osteosynthesis of proximal humerus fractures - results of a prospective, randomized trial.

BACKGROUND: The use of continuous passive motion therapy (CPM) has led to promising results in the early phase of rehabilitation after surgical treatment of rotator cuff tears and arthrolysis of the elbow. However, its use has not been proven in other pathologies of the upper extremity. Therefore, the aim of the underlying study was to evaluate the use of CPM therapy after plate osteosynthesis of proximal humeral fractures. METHODS: 95 patients with isolated proximal humerus fractures were enrolled in a prospective, randomized study. Patients were assigned to a treatment group with (n = 48, CPM) or without CPM therapy (n = 47, CG). Four patients (2 of each cohort) violated the study protocol and were excluded. CPM therapy was used for 6 weeks after surgery 2-3 times daily. Functional (range of motion) and patient reported outcomes (PROM, Constant Score [CSS], QuickDASH, subjective shoulder value [SSV], pain on visual analogue scale [VAS]) were evaluated at 6 weeks, 3 and 12months. 60 patients completed the 1-year follow-up. RESULTS: The average patient age was 65.3 years (min: 27, max: 88, SD: ± 14.7). Seventy-two patients were female (79%). There was no difference regarding injury severity (2/3/4 part-fracture: 6/32/7 vs. 9/26/11, p = 0.867) and sex (p = 0.08). However, patients in the CPM group were significantly younger (CPM: 67 [min: 34, max: 82], CG: 74 [min: 27, max: 88], p = 0.032). After 6 weeks we observed a better range of motion for forward flexion (CPM: 90° [min: 50°, max: 180°] vs. CG: 80° [min: 20°, max: 170°] p = 0.035) and abduction (CPM: 80° [min: 40°, max: 180°] vs. CG: 70° [min: 20°, max: 180°], p = 0.048) in the CPM group. There was no difference regarding the further planes of motion or the assessed PROMs at 6 weeks. At 3 and 12 months the results between the treatment groups equalized with no further significant differences. CONCLUSION: The treatment with CPM increases the range of motion after plate osteosynthesis of proximal humerus fractures in the first 6 weeks after surgery. This effect is not sustained after 3 and 12months. The evaluated PROMs are not being influenced by CPM therapy. Hence the results of this prospective randomized study suggest that CPM can be a beneficial asset in the early period of rehabilitation after proximal humerus plate osteosynthesis. TRIAL REGISTRATION: The study protocol was registered in the US National Institutes of Health's database ( http://www. CLINICALTRIALS: gov ) registry under NCT05952622.

Reparación del músculo pronador cuadrado en fracturas de radio distal tratadas con fijación interna por abordaje palmar: una revisión sistemática y metaanálisis / Repair of the pronator quadratus muscle in distal radius fractures treated with internal fixation through a palmar approach: a systematic review and meta-analysis

Introducción: el músculo pronador cuadrado funciona como un estabilizador dinámico de la articulación radiocubital distal. Su reparación posterior a la fijación interna con placa de bloqueo volar en fracturas distales del radio es controvertida. Objetivo: determinar si la reparación del músculo pronador cuadrado influye en los resultados clínicos y funcionales de pacientes con fractura de radio distal que se sometieron a reducción abierta y fijación interna con placa de bloqueo volar. Materiales y métodos: se realizó una revisión sistemática y metanálisis. Las bases de datos analizadas fueron PubMed/Medline, Embase y Bireme/Lilacs (búsqueda realizada hasta el 20 de febrero del año 2023). Los términos de búsqueda fueron: distal radius fracture AND volar plate AND pronator quadratus. Se determinó la calidad metodológica según el manual de revisiones Cochrane. Resultados: en total se incluyeron 4 ensayos clínicos aleatorizados de adecuada calidad metodológica, lo cual corresponde al análisis de 213 participantes. Existen mejores resultados en la puntuación DASH a los 12 meses de seguimiento en el grupo de no reparación del músculo pronador cuadrado DM 2,8 [IC 95%: 0,51;5,10]. No hubo diferencias significativas al año de seguimiento en las puntuaciones de dolor, rangos de movilidad de la muñeca, fuerza de agarre e incidencia de complicaciones. Conclusión: no existe evidencia que sustente la reparación rutinaria del músculo pronador cuadrado posterior a la fijación interna con placa de bloqueo volar en las fracturas de radio distal. (AU)

Introduction: the pronator quadratus muscle functions as a dynamic stabilizer of the distal radioulnar joint, and its repair after internal fixation with volar locking plate in distal radius fractures is controversial. Objective: to determine whether the repair of the pronator quadratus muscle influences the clinical and functional outcomes of patients with distal radius fracture who underwent open reduction and internal fixation with volar locking plate. Materials and methods: a systematic review and meta-analysis were conducted. The analyzed databases were Pubmed/Medline, Embase, and Bireme/Lilacs (search performed until February 20th, 2023). The search terms were distal radius fracture AND volar plate AND pronator quadratus. Methodological quality was determined according to the Cochrane Reviewer's Handbook. Results: a total of 4 randomized clinical trials of adequate methodological quality, corresponding to the analysis of 213 participants, were included. Better DASH scores were observed at 12 months of follow-up in the non-repair group of the pronator quadratus muscle, with a mean difference of 2.8 [95% CI 0.51; 5.10]. There were no significant differences at one-year follow-up in pain scores, wrist mobility ranges, grip strength, and incidence of complications. Conclusion: there is no evidence to support routine repair of the pronator quadratus muscle after internal fixation with volar locking plate in distal radius fractures. (AU)

Early weight bearing and mobilization decrease perioperative complications in patients after ankle fracture; the retrospective multicenter (TRON group) study.

BACKGROUND: Open reduction and internal fixation (ORIF) for unstable ankle fractures (AF) are relatively predictable with excellent outcomes. Rehabilitation strategies are still being debated after surgical intervention for AF: non-weight bearing and cast immobilization for six weeks after the surgical repair of unstable AF or early functional treatment with partial weight bearing. This study aimed to compare early weight bearing and functional outcomes and complications. METHODS: Between April 2014 and March 2019, 1421 patients with AF underwent ORIF at 11 institutions (TRON group). The patients were divided into two groups: Group E started weight bearing within six weeks after surgery, and group L started weightbearing for more than six weeks after. To adjust for baseline difference between groups, a propensity score-matched algorithm was used to match Group E with Group L in a 1:1 ratio of 294 cases each. We compared the American Orthopedic Foot and Ankle Society (AOFAS) score as the functional outcome, the rate of wound dehiscence, superficial and deep infections, blistering, nonunion, neurapraxia, and reoperation at 3, 6, and 12 months after surgery. RESULTS: The mean period of non-weight bearing was significantly shorter in group E (3.68 ± 1.02 vs. 6.67 ± 1.43; P < 0.001). The mean period of cast immobilization term were shorter in group E (1.84 ± 1.35 vs. 2.65 ± 1.51; P < 0.001). There were no differences in the AOFAS score at any period. The rates of deep infection and reoperation in Group E were significantly lower than those in Group L (1.7% vs. 6.1%; P = 0.009, 2.0% vs. 7.8%; P = 0.002, respectively). There were no significant differences in superficial infection (9 vs. 15; P = 0.297), nonunion (9 vs. 15 P = 0.30), blistering (4 vs. 3; P = 1.00), neurapraxia (2 vs. 1; P = 1.00), and wound dehiscence (15 vs. 18; P = 0.72). CONCLUSIONS: Although functional outcome was similar depending on whether early weight bearing was allowed, the rates of deep infection and reoperation decreased in patients with early weight bearing. We recommend early postoperative weight bearing in patients with a surgically treated AF.

A comparison of six outcome measures across the recovery period after distal radius fixation-Which to use and when?

PURPOSE: Many standardized outcome measures exist to measure recovery after surgical fixation of distal radius fractures, however, choosing the optimal instrument is difficult. We evaluated responsiveness, ceiling/floor effects, and criterion validity over multiple time intervals across a 2-year follow-up period for six commonly used instruments. METHODS: A total of 259 patients who received open reduction and internal fixation for distal radius fractures between 2012 and 2015 were recruited. Patients were administered the Patient-Rated Wrist Evaluation (PRWE), Shortened Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH), Green and O'Brien score (Cooney modification) (CGNO), Gartland and Werley score (Sarmiento modification) (SGNW), flexion-extension arc (FEArc), and grip fraction test (GripFrac) at 1.5, 3, 6, 12, and 24 months postoperatively. Responsiveness was evaluated by calculating standardized response means (SRM) and Cohen's d effect sizes (ES), and by correlating each instrument's change scores against those of QuickDASH and PRWE, which were also used as external comparators to assess criterion validity. Ceiling/floor effects were calculated for all measures at each time point. RESULTS: SRM (1.5-24 months) were 1.81, 1.77, 1.43, 1.16, 2.23, 2.45 and ES (1.5-24 months) were 1.81, 1.82, 1.95, 1.31, 1.99 and 2.90 for QuickDASH, PRWE, CGNO, SGNW, FEArc, and GripFrac respectively. Spearman correlation coefficients against QuickDASH at 24 months were: 0.809, 0.248, 0.563, 0.285, and 0.318 for PRWE, CGNO, SGNW, FEArc, and GripFrac respectively. Significant (>15% of patients reaching maximum score) ceiling effects were observed before 6 months for PRWE and SGNW. CONCLUSIONS: Our evidence supports the use of QuickDASH, PRWE, FEArc and GripFrac up to 6 months postsurgery, and QuickDASH and PRWE after 6 months. LEVEL OF EVIDENCE: Level II.

Outcomes After Surgical Fixation of Posterior Sternoclavicular Physeal Fractures and Dislocations in Children.

BACKGROUND: Acute sternoclavicular fractures and dislocations (SCFDs) are a rare but important injury in pediatric patients. SCFDs are either true dislocations, or more commonly, physeal fractures in children. The reduction is advised given the proximity to surrounding vascular structures, and some authors advocate for routine fixation given rates of redisplacement after closed reduction. The purpose of the current study was to provide validated long-term functional outcome data following open reduction and surgical fixation of pediatric SCFDs, as well as provide injury and demographic information. METHODS: This is a retrospective observational study with a subset of patients reporting functional outcomes. Patients under the age of 18 that had surgically managed acute posterior SCFD from 1990 to 2018 were included. A retrospective chart review was performed to obtain demographic, clinical, and surgical details. Patients with a minimum of 6-month follow-up were contacted to assess outcomes. Functional outcomes of interest included QuickDash, Visual Analog Scale pain rating, Single Assessment Numeric Evaluation of shoulder function, and PROMIS Upper Extremity questionnaire. Statistical analysis included descriptive statistics. RESULTS: A total of 37 patients that sustained an acute posterior SCFD during the study period were included. The average age at the time of injury was 15.2±2.1 years and 89% were male. Patient-reported outcomes were obtained for 14 patients with a mean follow-up of 4.5 years. The mean QuickDash score was 5.1/100 with 0 being normal, and the mean Visual Analog Scale pain rating was 0.7/10. The mean Single Assessment Numeric Evaluation score was 96% with 100% being completely normal. The mean PROMIS score was 55 with 50 being the mean of the relevant reference population. Approximately 29% (4/14 patients) stated that their injury negatively affected their ability to participate in sports. CONCLUSIONS: There is a paucity of literature on functional outcomes after surgical management of pediatric acute posterior SCFD. Functional outcomes after surgery were satisfactory in this cohort with most patients being able to perform major activities of daily living. Additional future studies with larger cohorts and comparative groups are needed to better understand outcomes in this population. LEVEL OF EVIDENCE: Level IV.

Calcaneal fracture: results of earlier rehabilitation after open reduction and internal fixation.

INTRODUCTION: This study aimed to analyze the clinical and radiological outcomes of early weight-bearing and rehabilitation after open reduction and internal fixation (OR/IF) of calcaneal fracture. MATERIALS AND METHODS: This retrospective study was conducted on 78 patients with unilateral calcaneal fracture who underwent OR/IF. A mean follow-up period was 45.8 months (range 12-135). Two weeks after surgery, the range of motion (ROM) exercise was started, brace or heel off shoe was applied, and forefoot weight-bearing was allowed. Four weeks after surgery, tolerable weight-bearing ambulation without crutch was allowed. When the patient was not walking, the braces were removed to perform peritalar ROM exercises. Radiologic evaluation was performed by measuring the Böhler angle and incongruency of the subtalar joint surface. Paley grade was used to assess traumatic arthritis. Clinical evaluation was performed by measuring the foot and ankle outcome score (FAOS) and ankle ROM. RESULTS: The mean postoperative Böhler angle was 31.7° (P < 0.001) at 2 weeks, 31.2° at 3 months, and 30.1° at the last (P = 0.4). The average Paley grade of the subtalar OA was 1.12. CT imaging revealed that the average step-off of the subtalar joint was 1.26 mm in coronal and 0.84 mm in sagittal. The average ROM results were as follows (contralateral, affected side): there was no significant difference in dorsiflexion [16.9° vs. 16° (P = 0.6)], whereas plantarflexion and inversion were significantly decreased [39.5° vs. 35.3° (P = 0.049) and 50.5° vs. 34.8° (P = 0.04)]. The average FAOS score was 86.1 points, and the highest score was "function" (mean 92.5 points). CONCLUSIONS: Earlier rehabilitation after OR/IF is recommended for the treatment of calcaneal fracture.

Clavicle Nonunion RepairWhat Can Patients Expect?

BACKGROUND: The purpose of this study was to compare the long-term functional status of patients treated surgically for a clavicular nonunion using patients treated either op-eratively or non-operatively for an acute clavicle fracture as a comparison group. METHODS: Twenty consecutive patients treated by a single surgeon for a clavicle fracture nonunion were identified. For comparison of outcomes, acute clavicle fractures were identified from an electronic medical record (EMR) query of the same orthopedic surgeon. Ninety acute clavicle fracture patients were identified and 27 (30%) patients were available for long-term follow-up. Clavicular nonunions were compared to acute clavicle fracture patients in a univariate analysis then a multivariate analysis to analyze clavicle nonunion patients against operative and non-operative acute clavicle fracture patients. The main outcome measures were time to bony union, postoperative complications, visual analog scale (VAS) pain scores, and Short Musculoskeletal Functional Assessment (SMFA) scores at long-term follow-up. RESULTS: There was no difference in time to healing or functional outcomes as assessed by SMFA and VAS pain scores between clavicle nonunion and acute fracture patients. Postoperative complications also did not differ between the groups. CONCLUSIONS: Patients who are treated surgically for clavicular nonunions ultimately regain a similar functional status as patients who are treated either operatively or non-operatively for an acute clavicle fracture and heal acutely.

Iliac intramedullary stabilization for Type IIIA fragility fractures of the pelvis.

There have been few reports on fixation of Rommens classification Type IIIA fragility fractures of the pelvis (FFPs). Here, we present our less invasive surgical technique, called iliac intramedullary stabilization (ILIS), for the internal fixation of Type IIIA FFPs. The technique involves a closed reduction, termed the femur internal rotation reduction method (FIRM), whereby the fracture fragments are repositioned using lateral rotators by internally rotating the femur while the patient is in the prone position. Two iliac screws are inserted on the ilium bilaterally via the supra-acetabular bone canal during FIRM and connected with two transverse rods and two cross connectors. We refer to this internal fixation procedure as ILIS. We retrospectively recruited patients with Type IIIA fractures, treated using this procedure, at our institute between October 2017 and October 2019. We evaluated operative and post-operative outcomes. We enrolled 10 patients (9 women and 1 man; mean age, 85.2 years) who were followed up for over 6 months. All patients suffered FFPs after falling from a standing position. The mean operative time was 145.1 (range, 94-217) minutes, and the mean blood loss was 258.5 (range, 100-684) ml. All patients were allowed full weight bearing from post-operative day 1. All patients achieved bone union and regained their pre-injury walking ability at 6 months after surgery without evident secondary displacement. In conclusion, our ILIS technique allows less invasive internal fixation of Type IIIA FFPs with adequate stability for full weight bearing from post-operative day 1.

Application of a novel shape-memory alloy concentrator in displaced olecranon fractures: a report of the technique and mid-term clinical results.

PURPOSE: Olecranon fracture is a common upper limb fracture, and several surgical approaches have been advocated for its fixation. To overcome the complications associated with common techniques, we present a novel shape-memory alloy concentrator, an alternative for tension band compression, to fix olecranon fracture. METHODS: Fifty-seven patients (26 men and 31 women) with olecranon fracture, with a mean age of 45 years, were included in this study. Each patient had undergone open reduction and internal fixation using the Nitinol (Ni-Ti) arched shape-memory connector (ASC). The clinical assessments were performed using the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire and the Mayo Elbow Performance (MEP) score, which were both recorded at the final follow-up visit. RESULTS: The patients were followed up for 44 months on average (range, 31 to 56 months). No patients were lost to follow-up, and all of the olecranon fractures healed in an average of 15 weeks (range, 10 to 34 weeks). The mean DASH score was 8.6 (range, 0 to 32.4), and the mean MEP score was 92.5 (range, 74 to 100). Nine patients showed postoperative complications: prominent hardware (2), infection (1), loss of the range of functional motion (5), and heterotopic ossification (1). CONCLUSION: The ASC may serve as a favorable device for multi-fragmented and comminuted fractures with rare hardware irritation and may also provide continuous concentrative compression to accelerate osseous healing, thereby aiding the restoration and permitting an early rehabilitation with a low incidence of postoperative complications.

Is there any change in surgeon's attitude to the management of ankle fractures accompanying syndesmotic injury? A nationwide survey.

OBJECTIVES: This study aims to investigate the attitudes of orthopedic surgeons to the management of ankle fractures accompanied by syndesmotic injury with a nationwide survey. PATIENTS AND METHODS: In the first step of this descriptive study, an electronic survey was prepared in Google drive and a survey link was sent to the Turk-Ortopedi e-mail group between 09 and 19 January 2019. The orthopedic surgeons and residents were requested to complete the questionnaire. A total of 320 orthopedic surgeons (77%) and residents (23%) participated in the survey. The responses were analyzed statistically. To evaluate the changing attitudes, our results were compared with the surgeon survey studies key worded "syndesmotic injury" in PubMed. RESULTS: The majority of the participants stated that they used the hook test, external rotation stress test, and fluoroscopy together (47.2%) for the diagnosis of syndesmotic injury during the operation. Of the participants, the majority (93%) reported to use metallic syndesmotic screws, and 59% reported to remove the syndesmotic screw routinely. Young surgeons with 5 to 10 years of experience preferred intraoperative diagnosis methods compared to surgeons with more than 20 years of experience. Foot and ankle surgeons and sports surgeons reported to allow weight bearing before removal of the screw much more than other unspecified branches. CONCLUSION: The preferences of the surgeon vary in syndesmotic injuries and there is still no consensus regarding diagnosis and rehabilitation. Compared to the past decade, fewer surgeons prefer to remove the screws today.

Radial neck fracture in children: anatomic and functional results of Metaizeau technique.

Fractures of the radial neck accounts for 1% of all childhood fractures and 5% to 10% of childhood traumatic lesions involving the elbow. Intramedullary percutaneous nail reduction (Metaizeau technique) is considered the most effective surgical technique. The purpose of this study was to identify the main clinical features of radial neck fracture in children and to evaluate the anatomical and functional results of the Metaizeau technique. In this retrospective study, we evaluated 22 patients under the age of 16 who were treated for radial neck fracture at the orthopedic and trauma surgery department of Sahloul University Hospital in Sousse over a period of 16 years from January 2001 to April 2017. Authors used Metaizeau classification. Functional results were evaluated by Mayo elbow performance score (MEPS) and the radiological evaluation was based on standard images with measurement of the residual rocker. The average age was 8.6 years (5-13 years). Seven fracture were grade III injuries and three grade IV. In the immediate postoperative period, radiological measurements showed a residual rocker less than 20° in 86.3% and more than 20° in 13.7% of cases. At an average follow-up of 13 months and a half, the MEPS score was excellent and good for 17 patients. Four types of complications were found: necrosis of the radial head in 1 case, pseudarthrosis in 1 case, periarticular calcification in 2 cases and stiff-ness of the elbow in 3 cases. Despite the small number of patients in our series, we believe that the elastic stable intramedullary pinning according to the Metaizeau technique is the treatment of choice for displaced radial neck fractures in children.

Rehabilitation after distal radius fractures: is there a need for immobilization and physiotherapy?

Although the literature generally agrees that displaced distal radius fractures require surgery, no single consensus exists concerning the length of immobilization and type of post-operative physiotherapeutic rehabilitation program. Palmar locking plate fixation represents a very stable fixation of the distal radius, and was assessed biomechanically in various studies. Surprisingly, most authors report additional immobilization after plate fixation. One reason might be due to the pain caused during active wrist mobilization in the early post-operative stages or secondly to protect the osteosynthesis in the early healing stages preventing secondary loss of reduction. This article addresses the biomechanical principles, current available evidence for early mobilization/immobilization and impact of physiotherapy after operatively treated distal radius fractures.

Better functional outcomes for ORIF in tibial eminence fracture treatment: a national comparative multicentric study of ORIF vs ARIF.

PURPOSE: Tibial eminence fractures can occur in adults and are equivalent to an acute ACL rupture. The purpose of this retrospective study was to compare the therapeutic outcomes of ARIF versus ORIF in tibial eminence fractures. Our hypothesis was that ARIF does not offer better results. METHODS: A retrospective national multicentric study was conducted in five university hospitals between 2010 and 2015. A total of 65 consecutive patients were included. 33 patients were treated with ARIF and 32 with ORIF. Clinical functional outcomes were assessed using the Lysholm score and IKDC score. Radiographic findings were recorded, and a statistical analysis carried out. RESULTS: IKDC score at the mean last follow-up of 68.8 ± 11.8 months was significantly higher in the ORIF group with a mean difference of 20.2 points ± 8.9 (p = 0.028). There were early osteoarthritis findings in 12 patients (18.4%). At last follow-up, 7 patients (10.7%) presented complications. CONCLUSION: In this retrospective multicentric study, better functional outcomes were observed in the ORIF group. This difference needs to be carefully interpreted as many confounding factors exist. In terms of complications, the results for both ORIF and ARIF are similar at midterm follow-up. ORIF should remain gold standard for tibial eminence fracture treatment. LEVEL OF EVIDENCE: III.

Displaced Clavicle Fractures in Cyclists: Return to Athletic Activity After Anteroinferior Plate Fixation.

BACKGROUND: One of the most commonly observed injuries in cycling is fracture of the clavicle. Nevertheless, there is limited literature available on clinical outcomes after plate fixation of clavicle fractures in cyclists, rehabilitation protocols, and the time to return to sports. PURPOSE: The aim of this study was to evaluate the functional outcome, complications, and return to athletic activity at short-term follow-up after surgical repair. STUDY DESIGN: Case series. METHODS: Between January 2008 and October 2014, all professional and recreational cyclists presenting with a new clavicle fracture at the emergency department were prospectively recorded. All patients had an anteroinferior plate fixation, variable angle locking compression plate (DePuySynthes). Patients were seen at 2, 6, and 24 weeks at the outpatient clinic to gather Disability of the Arm, Shoulder, and Hand (DASH) and Constant shoulder questionnaires and radiographs were made. Cyclists were allowed to resume outside training 1 week after surgery. RESULTS: Ten professional cyclists and 15 recreational cyclists were included. All (25/25) patients returned to cycling after plate fixation. Mean Constant scores and mean DASH scores of 96.8 ± 4.1 and 5.1 ± 5.5 at 6 weeks and 99.1 ± 1.5 and 2.9 ± 4.6 at 24 weeks were measured. There were 3 complications: 1 patient developed a nonunion, there was 1 wound infection requiring antibiotics, and in 1 patient, a refracture occurred. CONCLUSION: Plate fixation for cyclists with displaced clavicle fractures was successful in terms of fast return to previous level of athletic activity. It is a valuable and safe option for athletes in cycling.

Effects of a diabetes-specific care model for hip fractured older patients with diabetes: A randomized controlled trial.

OBJECTIVES: To examine the effects of a diabetes-specific care model for hip fractured elderly with diabetes mellitus (DM). METHODS: A randomized controlled trial was implemented in a 3000-bed medical center in northern Taiwan. Older adults (age ≥ 60) with DM who had hip-fracture surgery (N = 176) were recruited and randomly assigned to diabetes-specific care (n = 88) and usual care (n = 88). Usual care entailed one or two in-hospital rehabilitation sessions. Diabetes-specific care comprised an interdisciplinary care (including geriatric consultation, discharge planning, and in-home rehabilitation) and diabetes-specific care (including dietary and diabetes education, blood pressure control, dyslipidemia management, a glycemic treatment regimen, and rehabilitation exercises). Outcomes including heart rate variability; rehabilitation outcomes; activities of daily living and instrumental activities of daily living were assessed before discharge and 1, 3, 6, 12, 18, 24 months afterwards. RESULTS: Patients who received diabetes-specific care had significantly higher hip-flexion range of motion (b = 5.24, p < .01), peak-force quadriceps strength of the affected limb (b = 2.13, p < .05), higher total heart rate variability in terms of the time-domain parameter for the mean squared difference between two adjacent normal R-R intervals (b = 11.35, p < .05), and frequency-domain parameters, such as low frequency (b = 42.17, p < .05), and the high frequency-to-low frequency ratio (b = 0.11, p < .01). CONCLUSIONS: Our diabetes-specific care model enhanced hip-flexion range of motion, peak quadriceps strength of the affected limb, and overall heart rate variability, indicating dynamic responses to environmental changes during the 24 months following hospital discharge, above and beyond the effects of usual care.

The Relationship between Hand Therapy and Long-Term Outcomes after Distal Radius Fracture in Older Adults: Evidence from the Randomized Wrist and Radius Injury Surgical Trial.

BACKGROUND: Older patients are frequently referred to hand therapy after distal radius fracture. Supervised therapy sessions place a transportation burden on patients and are costly on both the individual and systematic levels. Furthermore, there is little evidence that supervised therapy or home exercises improve long-term outcomes. METHODS: Data were collected for the Wrist and Radius Injury Surgical Trial, a multicenter, international, pragmatic, randomized trial of distal radius fracture treatment in patients aged 60 years and older. Referral to therapy and therapy protocol were at the discretion of the treating surgeon and therapist. The authors examined outcomes between participants who underwent therapy and those who did not and assessed the duration of therapy. The authors also analyzed the effect of therapy on subgroups at risk for poor outcomes: older participants and those who had more comorbidities or lower baseline activity. RESULTS: Eighty percent of participants underwent therapy; 70 percent participated in both supervised therapy and home exercises. Participants had a mean 9.2 supervised sessions over 14.2 weeks. There were no differences in patient-reported outcomes between participants who underwent therapy and those who did not. Participants who did not have therapy recovered more grip strength. Participants who engaged in therapy for a shorter time reported greater function, ability to work, and satisfaction. There were no relationships revealed in subgroup analyses. CONCLUSIONS: Hand therapy after distal radius fracture may not be necessary for older patients. Encouraging participants to resume activities of daily living as soon as possible may be as effective as formal therapy. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Clinical observation of C3-type patellar fractures treated by operation methods with or without a turned-over patella.

OBJECTIVE: To evaluate the clinical efficacy of operation methods with or without a turned-over patella for treatment of C3-type patellar fractures. METHODS: A total of 68 patients with C3-type patellar fractures undergoing open reduction and internal fixation were retrospectively selected and treated with a turned-over patella surgery (turned-over patella group, n = 30) or conventional therapy without turning over the patella (conventional group, n = 38). The intraoperative and postoperative indicators of the two groups were assessed and comparatively analyzed. RESULTS: The bedridden time was significantly shorter in the turned-over patella group than in the conventional group (P = 0.002), while the range of motion (ROM) of knee joint was significantly higher in the turned-over patella group (P = 0.044). The Lysholm score was slightly higher in the turned-over patella group than in the conventional group, but the difference was not statistically significant (P = 0.055). No significant difference was observed between the two groups in terms of the operation time (P = 0.096), intraoperative blood loss (P = 0.543), time of weight bearing (P = 0.312), fracture healing time (P = 0.272), or complications (P = 1). CONCLUSION: The turned-over patella operation method exhibited some superiority to conventional reduction-fixation approach for treatment of C3-type patellar fractures in terms of efficacy and safety by enlarging the ROM of the knee joint and promoting functional recovery.

Use of a stainless steel locking calcaneal plate for quadrilateral plate buttress in the treatment of acetabular fractures.

Operative fixation of acetabular fractures involving the quadrilateral surface presents a challenging clinical scenario. Classically, quadrilateral plate buttress was achieved via the use of a "seven" plate. More recently, the use of an anatomic, pre-contoured design has been gaining popularity due to its pre-contoured shape and larger footprint, allowing for a wider quadrilateral plate buttress. The current study presents using a stainless steel locking calcaneal plate to obtain similar surface area coverage as the modern pre-contoured quadrilateral plate, but at a lower cost.Level of evidence IV.

Repair and augmentation of the lateral collateral ligament complex using internal bracing in dislocations and fracture dislocations of the elbow restores stability and allows early rehabilitation.

PURPOSE: Most elbow dislocations can be treated conservatively, with surgery indicated in special circumstances. Surgical options, apart from fracture fixation, range from repair or reconstruction of the damaged ligaments to static external fixation, usually entailing either a long period of immobilization followed by carefully monitored initiation of movement or dynamic external fixation. In general, no consensus regarding surgical treatment has been reached. A new method of open ligament repair and augmentation of the lateral ulnar collateral ligament using a non-absorbable suture tape in cases of acute and subacute elbow instability following dislocations has been described here, which allows an early, brace-free initiation of the full range of motion. This is the first description of the technique of internal bracing of the lateral elbow with preliminary patient outcome parameters for acute treatment of posterolateral rotatory instability. METHODS: Seventeen patients (14 males and 3 females) with acute or subacute posterolateral elbow instability as a result of dislocation or fracture dislocation were treated in our centre (Sporthopaedicum, Straubing, Regensburg, Germany) from 2014 to 2015 with open LUCL re-fixation and non-absorbable suture tape augmentation. The elbows were actively mobilized immediately after the operation and a maximum bracing period of 3 days. RESULTS: At 10 month median follow-up, none of the patients showed clinically apparent signs of instability or suffered subluxation or re-dislocation. One patient required re-operation for heterotopic ossification. The median range of motion was from 10° (0-40) to 130° (90-50) and median Oxford, Mayo Elbow Performance score, Simple Elbow Value, and DASH Scores were 41(29-48), 100 (70-100), 83% (60-95), and 18.5 (1.6-66), respectively. All patients reported a complete return to pre-injury level of activity. CONCLUSION: Augmentation with a non-absorbable suture tape acting as an 'Internal Brace' following an elbow dislocation is a safe adjunct to primary ligament repair and may allow the early mobilization and recovery of elbow stability and range of motion. LEVEL OF EVIDENCE: IV.

Pitfalls and limits of locking plates.

The use of locking plates relies on novel mechanical and biological concepts: the bone healing is endochondral because of the elasticity of the constructs. Preoperative planning is required to determine the fracture reduction strategy and select the implants. The type of plate and the type of screws and their position determine the mechanical properties of the construct. Failure of locking plate fixation is a new phenomenon that differs from conventional plate fixation. These are brought on by inadequate planning, which is made worse when minimally invasive surgery is performed. Often, the fracture is not reduced correctly (leading to malunion), the implant length is incorrect, or the screw type, number, location and implantation sequence are inappropriate. Together these can result in an overly rigid construct with poor healing and implant failure or the opposite, an overly flexible construct that can compromise healing. The return to weight bearing after fracture fixation must be adapted to the type of fracture and construct. While locking plates provide better bone purchase, especially in osteoporotic bone, "en bloc" pulling out of the implant is possible. Delayed fractures at the end of the plates are also possible but can be avoided by making the correct biomechanical choices during fixation. For epiphyseal fractures, there are risks of cut-out and impaction of locking screws in cancellous bone related to the fracture pathology. In the long-term, locking plates can be difficult to remove; however, specialized instrumentation can make this easier.
