Heterotrophic ossification (HO) is a reactive disease presenting the formation of mature lamellar bone in soft tissues. It is known to occur following surgery, soft tissue injury, or central nervous system anomalies. However, a definite cause has not yet been clearly addressed. During the process of approach, reduction, and fixation while conducting surgeries, partial injury of soft tissue is inevitable. Additionally, secondary injuries may be caused during the active and passive range of motion exercises that should be done for the recovery of joint motion after surgery. The authors experienced cases of HO that may occur during surgery and rehabilitation after surgery. The authors recognized that special care is required for patients complaining of severe pain during the early stage of rehabilitation immediately after surgery. This study aimed to reaffirm the principles of fracture treatment by reviewing the cases and to investigate the occurrence of HO after fracture surgery.

Gouty arthritis is a common crystal arthropathy, but gout tophus in the bipartite patella is a rare condition. This report presented a traumatic separation of bipartite patellar fragment caused by mild trauma in a patient with comorbid gout. When a patient with bipartite patella and underlying gouty arthritis complains of pain after trauma, clinical suspicion is needed about fragment separation of the bipartite patella.

Minimally invasive plate osteosynthesis (MIPO) is beneficial for proximal tibial fractures since these injuries are mostly caused by high energy traumas. The advantages of MIPO are minimization of soft tissue dissection and preservation of periosteal vascularization. Lateral plating has mostly developed as MIPO for proximal tibial fractures. We introduce minimal invasive percutaneous plate stabilization using a medial locking plate as alternative treatment for proximal tibial fractures.

PURPOSE: To evaluate the advantages of reduction of lateral and posterior displacement in unstable intertrochanteric fractures of the elderly. MATERIALS AND METHODS: From January, 1997 to December, 2001, we reviewed 23 cases of unstable intertrochanteric fractures in the elderly, which underwent by reduction of lateral and posterior displacement. Using the device of internal fixation is dynamic compression hip screw (DHS), the follow up period was minimally 12 months (mean 16 months). We estimated the clinical results, the radiologic results and complications. RESULTS: The satisfactory results was regarded as walking with walking frame and 21 cases (91.3%) showed satisfactory results. The average period of radiologic union was 18 weeks. The average sliding of lag screw was 5.3 mm and the average changes of femoral neck-shaft angle was 2.6 degree. As for the complications, 2 cases showed superficial infection and 2 cases showed pain over trochanteric area. CONCLUSION: In the unstable intertrochanteric fractures of the elderly, treatment with reduction of lateral and posterior displacement can be considered one of reduction technique.

A few cases of femoral neuropathy that were developed after renal transplantation have been reported in western literature. The possible causes of this neuropahty that discussed in recent studies are compression of nerve by self-retaining retractor during operation, ischemia of femoral nerve by iliac muscle hematoma etc. We experienced one case of femoral nerve neuropathy after right iliac fossa renal transplantation that developed at first postoperative day without definitive etiology in all study. It was improved symptomatically after 2 weeks of postoperative day, so we reported this case with brief review of the literatures.

We evaluated the conditions required for sutures tied to a post for tibial fixation during anterior cruciate ligament (ACL) reconstruction. Harvested porcine tendon was used as a graft material and nonabsorbable suture was used for sutures. Samples were tested for ultimate tensile load and elongation according to thread numbers, knot numbers, suture techniques and stitch numbers. As thread numbers were increased, ultimate tensile load was increased and elongation was decreased. However, more than 4 strands of threads provided the sufficient ultimate tensile load more than 454 N of normal ACL for daily activities. As knot numbers were increased, ultimate tensile load was increased, but elongation was decreased. In terms of failure mode, unraveling occurred 100% in 3 and 4 knots, 81.2% in 5 knots, 54.5% in 6 knots, and 0% in 7 knots. Suture techniques and stitch numbers didn't significantly affect the ultimate tensile load and the elongation. For sutures tied to a post for tibial fixation in ACL reconstruction, more than 4 threads, more than 7 knots, and more than 4 stitches provide adequate ultimate tensile load and elongation.

PURPOSE: This goal of this study is to evaluate the clinical and radiological outcomes of proximal tibial comminuted fractures treated with medial minimally invasive percutaneous plate osteosynthesis (MIPPO). MATERIALS AND METHODS: We evaluated 43 patients who underwent medial MIPPO from February 2008 to February 2012 and were followed up for more than one year. According to the AO/OTA classification, there were 30 patients of 41-A3 and 13 patients of 41-C2. Thirty-six patients had closed fractures and seven patients had open fractures. We assessed clinical outcomes, radiologic results and postoperative complications. RESULTS: All fractures were united at an average of 18.3+/-8.1 weeks except three patients with nonunion. According to Schatzker and Lambert assessment, excellent results were achieved for 22 patients and good results were achieved for 21 patients. The average tibial plateau angle was 89.1degrees+/-2.7degrees and the average posterior tibial slope angle was 10.5degrees+/-4.6degrees. In assessment of lower limb alignment, the average femorotibial angle was 175.1degrees+/-2.9degrees and the mean deviation of mechanical axis was 46.5%+/-12.7%. In terms of complications, three patients had nonunion, but complete bony union was achieved by autogenous cancellous bone grafting. Seven patients complained of skin irritation around the plate. However, there was no skin necrosis, infection, or limited range of motion in seven patients with skin irritation. CONCLUSION: Medial MIPPO for proximal tibial comminuted fractures provides favorable clinical outcomes and good radiological alignments.

PURPOSE: The purpose of this study is to compare the clinical and radiological results between posteromedial portal technique and posterior transseptal portal technique in making a tibial tunnel in single bundle posterior cruciate ligament (PCL) reconstruction with remnant preservation. MATERIALS AND METHODS: Thirty-three cases of posteromedial portal technique and 35 cases of posterior transseptal portal technique in making a tibial tunnel in single bundle PCL reconstruction with remnant preservation were evaluated retrospectively. The clinical evaluation, including function and stability, was assessed. The tibial tunnel placement was measured using computed tomography. RESULTS: At final follow-up, the clinical results showed significant improvement compared to preoperation in both groups. There were no significant differences in clinical results including function and stability in both groups. The centers of tibial tunnels by posteromedial portal technique were placed more medially and proximally than those of the posterior transseptal portal technique. CONCLUSION: Remnant preserved single bundle PCL reconstructions by posteromedial portal technique and posterior transseptal portal technique were good methods for restoring function and stability compared to preoperation. There were no significant differences in clinical results in both groups. However, the tibial tunnels by posteromedial portal technique tended to be more medial and proximal placements than those of the posterior transseptal portal technique.

Purpose: To evaluate the value of an open wedge high tibial osteotomy (HTO) using a Locking Compression Plate(R) (LCP(R)) as a surgical technique. Materials and Methods: From May, 2003 to January, 2005, eleven open wedge HTO using LCP(R) were performed and the average follow-up period was 17.8 months. The knee score and function score for the clinical results, and the degree of varus deformity, the size of the joint space, the posterior tibial slope and the medial instability for radiography results were evaluated. Results: The knee score improved from 54.8 points to 95.9 points, and the function score improved from 57.3 points to 88.2 points. The femorotibial angle was corrected from 4.1degrees varus to 9.9degrees valgus. The posterior tibial slope did not show any significant change. The size of the joint space increased from 3.3 mm to 4.3 mm. No medial instability was observed. Conclusion: An open wedge HTO using LCP(R) achieved a corrected angle, reduced loss of the corrected angle, and an improved knee function. The surgical technique prevented the posterior tibial slope from increasing.
