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.

Sıçan segmenter kemik defekti modelinde trombositten zenginleştirilmiş plazmanın ve demineralize kemik matriksinin kırık iyileşmesi üzerine etkisinin karşılaştırılması

BACKGROUND Delayed union of fractured bone is one of the main problems of orthopedics and traumatology practice. It was hypothesized that the beneficial effects of allogeneic platelet-rich plasma (PRP) would be valuable in the treatment of segmental bone defects. This study is a comparison of the effects of demineralized bone matrix (DBM) and PRP in a segmental bone defect model. METHODS Total of 48 Wistar albino rats were separated into 4 groups. Segmental bone defect was created at right radius diaphysis in all specimens using dorsal approach. Four additional rats were used as PRP source. Intracardiac blood was withdrawn before the operation for preparation of allogeneic PRP. Group 1 (n=12) served as control group and defects were left untreated. Group 2 (n=12), was PRP group, and received grafting with PRP. Group 3 (n=12) was PRP+DBM combination group, and was treated with grafting and mixture of DBM and PRP. In Group 4 (n=12), defect area was grafted with DBM only. At the end of 10th week, rats were sacrificed, forearms were dissected, and defect areas were examined with radiological and histopathological parameters. RESULTS Radiological evaluation revealed that ossification was best in PRP group, followed by DBM group. According to results of histopathological studies, union quality was better than control group in all treatment groups (Groups 2, 3, and 4), and was best in PRP group (p<0.05). Results were also better in PRP group when examined in terms of cortex development and remodeling (p<0.05). When examined in terms of new osteogenesis, results were comparable in Groups 2, 3, and 4, but all were better than control group. CONCLUSION It was concluded that PRP and DBM have comparable effect on recovery of defective bones, but there is no synergistic effect when used together. We believe that PRP can be a cost-effective, readily available alternative to DBM with minimal morbidity.

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.

Axillary artery entrapment following proximal humeral fracture: a case report and review of literature

Injury to the axillary artery following proximal humerus fracture is a very rare occurrence. The most common mechanism of axillary artery injury is fracture dislocation, resulting with intimal tears, arterial lacerations or avulsions. The most common lesion is the subtotal transaction of the vessel. In this report, we aim to define entrapment of axillary artery by tethering of anterior circumflex humeral artery, which is an unreported mechanism of injury that occurred after a proximal humerus fracture. Diminution of pulse with abduction of arm was the only finding at initial examination, and diagnosis was confirmed with angiography. Treatment was accomplished through ligation and release of anterior circumflex artery with reduction and fixation of fracture fragments, resulting with full recovery. We also have reviewed current literature about axillary artery injuries following proximal humeral fracture.

Evaluation of Short Term Outcomes of Transportal Femoral Cross Pin Fixation in Anterior Cruciate Ligament Reconstruction

Objectives: Many fixation techniques are currently in use for femoral side graft fixation at ACL reconstruction surgery. Short term success following ACL reconstruction highly depends on fixation strength of the graft. In this study we report short term results of anterior cruciate ligament reconstruction using double hamstring tendon autograft using double cross pin for femoral tunnel fixation. Methods: Between years 2009 and 2013, 51 male adult anterior cruciate ligament injury cases treated surgically, in a single center, with at least one year follow up were investigated. Professional athletes, multi-ligamentous instability cases, cases requiring meniscus repair or further treatment for chondral injuries and cases with concomitant medial and lateral meniscus lesions were not included in the study. Femoral tunnel was prepared anatomically through accessory medial portal, opened medially and distally. Reconstruction was performed using double loop hamstring tendon autograft. Femoral side was fixed using double cross pin, whereas tibial side was secured using single biodegradable interference screw and titanium staple. No external immobilization method such as brace was administered. Patients were encouraged to bear weight as tolerated. Standard physiotherapy was instructed to all patients postoperatively. All cases were evaluated clinically at the end of at least one year follow-up. Clinical and functional evaluation consisted of pivot shift and Lysholm, International Knee Documentation Committee (IKDC) scores and Tegner activity evaluation systems. Results: Mean age was 28.4 (18-39) years. Mean time between the injury and reconstruction was 13 (3-21) weeks. Average duration of surgery was 48 (35-70) minutes. No case of graft failure or posterior cortical fracture was encountered. In two cases, infection was treated successfully with local debridement and antibiotics with retention of the graft. At the end of follow-up period, none of the cases demonstrated positive pivot shift test. Pre-operative and follow-up Lysholm scores were 58.3±6.7 and 87.1±5.3 (p<0.001) respectively. Pre-operative IKDC scores were evaluated as C at 37 cases and D at 14, whereas, follow-up IKDC scores were evaluated as A at 42 cases, B at 8 and C at 1 case. Pre-operative and follow-up Tegner scores were 3.7±0.6 and 6.7±0.4 (p<0.001) respectively. Conclusion: Although fixation strength of transcondylar graft fixation techniques has been questioned over loop systems with cortical fixation, it was reported that transcondylar fixation causes less tunnel widening at long term. Our study revealed successful short term results, with femoral tunnel preparation using accessory medial portal and double cross pin femoral fixation, allowing early weight bearing and rehabilitation without graft and fixation failure.

Opening Wedge High Tibial Osteotomy Using Tricalcium Phosphate Wedge Preliminary Results

Objectives: High tibial osteotomy is a standard procedure indicated for early medial sided osteoarthritis in varus knees. In this study, we present the early results of high tibial open wedge osteotomy cases using beta-tricalcium phosphate as a graft substitute and Otis-c plate. Methods: Between years 2010 and 2013, 47 cases of (34F, 13 M) medial compartmental gonarthrosis with genu varum deformity treated with high tibial osteotomy, were evaluated with at least one year follow-up, preoperatively both clinically and radiologically. Clinical evaluation involved functional assessment and pain evaluation using Lysholm and visual analog scale (VAS) scores, including knee range-of-motion. Radiological evaluation included medial joint space measurements on weight bearing knee radiographs with measurements of varus angle and posterior tibial slope. Surgical procedure included standard arthroscopy followed by medial sided opening wedge osteotomy with correction of the varus deformity using β- tricalcium phosphate graft substitute and fixation of the osteotomy site using Otis-C plate and locking screws. All patients were evaluated at the end of minimum one-year follow-up period. Results: Mean age of the patients was 56,7 (50- 65) years and mean follow-up period was 24,5 (12- 44) months. Mean duration of surgery was 47,4±10.2 minutes. No case of nonunion, delayed union, neurovascular injury or iatrogenic fracture was encountered. Two cases developed deep vein thrombosis and one case developed superficial wound infection managed successfully by local debridement with retention of implants and antibiotics. Mean duration of union was 13,4±2.7 weeks. Mean preoperative and follow-up range-of-motion were measured as 131±8.9 and 129±9.1 respectively with no statistical difference. Preoperative and follow-up VAS scores showed significant difference as 7.6±1.76 and 2.3±1.08 respectively (p=0.001). Also Lysholm scores improved significantly at the end of the follow-up period (43.23±4.01 vs. 76.3±3.7 p<0,001). Radiological evaluation revealed mean correction angle of 10.84±2.70 degrees at follow-up. Mean posterior tibial slope was measured relatively unchanged (8.6±1.70° degrees preoperatively versus 8.2±2.30° follow-up). Medial joint space width measurements showed a significant increase (pre-op 3.7±1.6 mm. versus 4.6±1.32 mm. at the follow-up (p<0.001)). Conclusion: Medial opening wedge osteotomy for treatment of early medial compartment gonarthrosis in varus knees is still a valuable option. Our short term preliminary results using beta-tricalcium phosphate wedge graft substitute and Otis-c plate-screw osteosynthesis revealed satisfactory short term clinical and radiological results with acceptable complication rates.
