Pulmonary thromboembolism after surgical treatment of ulnar pseudoarthrosis: a case report.

Deep vein thrombosis (DVT) and the consequently developed pulmonary embolism are devastating complications in orthopedic surgery. DVT occurs less frequently (1-2% of all cases) in the upper extremity than the lower extremity. We report a 54-year-old male patient who developed DVT and pulmonary thromboembolism after surgical treatment of an ulnar pseudoarthrosis. The presented case suggested the use of a low molecular weight heparin prophylaxis after upper extremity surgeries necessitating long-term immobilization.

Traction table versus manual traction in the intramedullary nailing of unstable intertrochanteric fractures: A prospective randomized trial.

INTRODUCTION The purpose of this prospective randomized study was to compare traction table with manual traction for the reduction and nailing of unstable intertrochanteric femur fractures. DESIGN Prospective, randomized, two-center trial. MATERIALS AND METHODS 72 elderly patients with AO/OTA 31A2 and 31A3 proximal femur fractures were randomized to undergo surgery with either manual traction (MT) or traction table (TT) facilitated intramedullary nailing. The demographics and fracture characteristics, duration of preparation and surgery, total anaesthesia time, fluoroscopy time, blood loss, number of assistants, early post-operative radiological evaluations and 6th month functional and radiological outcomes were evaluated. Data of 64 patients attending 6th month follow-up examination were evaluated statistically. RESULTS No significant differences were observed between groups regarding demographics and fracture characteristics. In the manual traction group, there was a significant time gain in respect of the positioning and preparation period (18.0±1.6min in MT group, 29.0±2.4min in TT group) (p<0.05). In terms of total anaesthesia time (Preparation+surgery) approximately 6min of difference was observed in favor of MT group (72.8±14.0min for MT and 78.6±6.5min for TT, [p<0.05]). Median number of assistants needed was significantly lower in TT group (2 assistants [1-3]) in MT group and (1 assistant [1,2]) in TT group [p<0.05]). There was no significant difference between two groups regarding other surgical and outcome parameters. CONCLUSIONS Manual traction reduced the preparation time and total anaesthesia duration, despite an increase in number of surgical assistant. LEVEL OF EVIDENCE Level II.

Parosteal lipoma as a rare cause of peripheral neuropathy and local irritation: A report of 12 cases

Objective The aim of this study was to evaluate the clinical features and functional results of patients with parosteal lipomas. Methods A total of 12 patients (8 females and 4 males; mean age: 45 (10–62) years) with parosteal lipomas who were treated between April 1986 and April 2014, were included into the study. The medical records of the patients were reviewed to analyze the clinical features and functional results of the patients. Results Of the 12 lipomas, 5 were localized in the proximal arm, 4 in the forearm, 1 in the distal arm, 1 in the distal thigh and 1 in the distal tibia. All patients presented with a progressive, slow-growing mass that was associated with thumb extension weakness in 1 case, and brachialgia-like symptoms in 1 case. Plain radiographs showed a juxtacortical mass in all cases and irregular ossification in 3 cases. In all cases, marginal excision was performed and no clinical recurrence was observed after a mean follow-up of 16 months. Conclusion Parosteal lipomas are uncommon tumors that can be diagnosed with their characteristic radiological features. Parosteal lipomas occurring in the proximal radius may easily cause paralysis of the posterior interosseous nerve or muscle weakness. Level of Evidence Level IV, Therapeutic study

Conventional trans-tibial versus anatomic medial portal technique for femoral tunnel preparation in anterior cruciate ligament reconstruction; comparison of clinical outcomes.

AIM Method of femoral tunnel preparation in anterior cruciate ligament (ACL) reconstruction is controversial. In this study, we aimed to determine if there is any difference between the clinical outcomes of two most commonly used drilling techniques; which are conventional trans-tibial (TT) drilling of femoral tunnel and anatomic preparation of femoral tunnel through medial portal (MP), in patients who underwent ACL reconstruction. MATERIAL AND METHODS One hundred and twenty-nine male patients who underwent ACL reconstruction between 2010 and 2012 were included in the study. Single-bundle reconstruction with a quadrupled autologous hamstring graft was performed in all patients. Femoral tunnel was drilled by the conventional TT technique in 58 patients (Group 1) and through MP in 71 patients (Group 2). Functional evaluation was made about 12 months postoperatively. Functional evaluation included the Lysholm Knee Scale, International Knee Documentation Committee Scoring (IKDC), and Tegner Activity Level Scale were used for assessment. The anteroposterior stability was assessed using KT-1000 arthrometer and the pivot shift test for assessment of rotational stability. RESULTS Interval between injury and surgery was similar between two groups (median 8.0 vs. 10 weeks, for TT vs. MP, respectively). One hundred twenty-five patients attending the final follow-up examination (96.8%) were evaluated. The results of Lysholm, IKDC, and Tegner scales were found to be similar. According to KT-1000 arthrometer results, MP group revealed slightly better results than TT group. Regarding pivot shift, MP group showed significantly better stability than TT group (P < 0.001). CONCLUSION The anatomical single-bundle femoral tunnel preparation in the reconstruction of the ACL seems as effective as the conventional technique in terms of functional stability in the midterm. The technique better preserved the rotational stability in non-professional athletes.

Effect of intramuscular botulinum toxin-A in a rat rotator cuff repair model: an experimental study.

OBJECTIVE Rotator cuff repair is associated with multiple complications, significant morbidity, and reintervention, which could be mitigated by postoperative chemodeneveration with botulinum toxin-A (BTX-A). This study evaluated the antinociceptive and paralytic effects of BTX-A on an experimental supraspinatus repair rat model and its effect on functional outcomes (running performance). METHODS Thirty rats were grouped into the surgical repair group (group A), repair + intramuscular BTX-A group (group B), or control group (group C). At the end of the 3-month follow-up, running performance of the rats on a motorized treadmill was evaluated in four time periods (0-30 min, 30-60 min, 60-90 min, and 90-110 min), and penalty points (i.e., number of shock stimuli per lane) were recorded. Afterwards, the supraspinatus muscles were removed and evaluated histologically. RESULTS Regarding running performance, group B received significantly fewer penalty points than did group A (p<0.05). The penalty points received were not significantly different between groups B and C in the first three time periods, but were significantly higher in group B at the 90-110-min interval than in group C. On necropsy, all repaired tendons were intact, with no sign of failure at the repair site. Histological evaluation revealed marked degeneration and necrosis of muscles in both repair groups, which was much less evident in group B. Groups A and B had less fatty infiltration than group C. CONCLUSION BTX-A injections resulted in a better function based on running performance, probably due to decreased tissue tension at the repair site and less pain. Further studies on humans are needed to demonstrate this effect clinically.

Comparison of two closed surgical techniques at isolated pediatric radial neck fractures

INTRODUCTION This paper aims to compare the clinical and radiological results of children operated using elastic stable intramedullary nailing as described by Métaizeau to those with the closed reduction and percutaneous pinning (CRPP). METHODS Results of 21 pediatric patients with radial neck fracture who were treated by two pediatric surgeons between January 2011 and December 2013 were reviewed retrospectively. 10 were treated with the Métaizeau method versus 11 with the CRPP. Operation time, fluoroscopic exposure time, Mayo elbow performance score (MEPS) and radiological assessment at final follow-up 1 year or greater and complications were main outcome measures. RESULTS The MEPS were excellent in all the patients of both groups. Reduction quality was excellent in 8 patients and good in 2 of the Métaizeau, and excellent in 9 and good in 2 of the CRPP. The fluoroscopy and operating times were statistically significantly greater, 3-fold and 2-fold respectively, in the Métaizeau method compared to the CRPP with comparable functional and radiological results. CONCLUSION Surgeon should adhere to a closed surgical method of his/her experience for excellent result. LEVEL OF EVIDENCE Therapeutic Level III.

Utility of Third-Week Postoperative Radiographs in the Management of Ankle Fractures

Objectives. To evaluate the costs and efficacy of radiographs taken in the third week after fixation of bimalleolar and trimalleolar fractures. Patients and method. A retrospective evaluation was made of patients who underwent surgical fixation because of bimalleolar and trimalleolar fractures between January 1, 2008, and October 1, 2013. Patient demographics (age, gender, body mass index), fracture type, follow-up periods, and fixation methods were recorded, and the radiographs taken on postoperative day 1, at 3 weeks, 6 weeks, and the final follow-up were examined by 2 orthopedists. Measurements were taken of the medial clear space (MCS ≤ 4 mm), the tibiofibular clear space (TFCS < 5 mm), and the talocrural angle (TCA = 83° ± 4°) on the mortise radiograph and of the overlap between the tibial tubercle and fibula (TFO > 10 mm) on the anteroposterior radiograph; residual step (mm) was measured on the lateral radiograph. Results. A total of 263 patients were examined, and of these, 112 were included for evaluation. In the measurements of postoperative day 1, third week, and sixth week and the final radiographs, no statistically significant difference was determined in the MCS, TFCS, TCA, TFO, and residual step values.
