Minimally Invasive Osteosynthesis with Locking Compression Plate for Distal Tibia Fractures

PURPOSE: To evaluate the outcome of minimally invasive osteosynthesis using locking compression plate for distal tibia fractures. MATERIALS AND METHODS: Forty five patients (45 cases) who underwent minimally invasive osteosynthesis using locking compression plate for distal tibia fractures between January 2006 and June 2008, were followed for more than one year. The average duration of the follow-up was 30.5 months (12~54 months). The fracture types were as followed: 26 cases (58%) of extraarticular fractures, 19 cases (42%) of intraarticular fractures, and 16 cases (36%) of open fractures. RESULTS: All patients achieved bone union at average of 21weeks (12~36 weeks). The average American Orthopedic Foot & Ankle Society ankle-hindfoot scales was 84.6 points (65~100 points) and range of ankle motion averaged at 46.5 degrees (20~60 degrees). Complications included 6 cases of superficial infection, 3 cases of malalignment and 5 cases of skin irritation by plate. There were no cases of deep infection, skin necrosis, shortening and metal breakage. CONCLUSION: Minimally invasive osteosynthesis using locking compression plate for distal tibia fractures is considered to be an effective method with high healing rate, rapid functional recovery and low complication rate due to minimal disruption of bone and soft tissue biology and improved fixation strength.

Pathologic Fracture of Proximal Femur with Benign Bone Tumor / 대한정형외과학회잡지

PURPOSE: The treatment results for a proximal femur fracture caused by a benign bone lesion were evaluated. MATERIALS AND METHODS: Nineteen patients (23 cases) who had been treated for proximal femur pathologic fracture from 1987 to 2002 were enrolled in this study. The mean follow-up duration was 40 months. The causes and treatments of the pathologic fractures and complications such as nonunion, deformity and recurrence were evaluated. RESULTS: The benign bone lesions treated were fibrous dysplasia (15), simple bone cyst (3), aneurysmal bone cyst (2), giant cell tumor (2) and eosinophilic granuloma (1). An autograft (3), allograft (2), and both autograft and allograft (3) was performed after adjuvant curettage with a high-speed burr. There was no recurrence in these 8 cases. At the final course, internal fixation was performed in 18 cases (intramedullary nail (10), compressive hip screw (6), plate (1), screw (1)), a hip spica cast 3 cases and a THR 2 cases. Three cases where a hip spica cast had been performed showed a varus deformity. A refracture and deformity were prevented in 10 cases who underwent intramedullary nailing. CONCLUSION: The IM nail is very effective in preventing complications such as a deformity, refracture after a treatment for polyostotic fibrous dysplasia. However, in a solitary benign bone lesion, bone graft and internal fixation is effective after thorough curettage.

Negative Pressure Wound Therapy for Traumatic Soft Tissue Defects

PURPOSE: To evaluate the negative pressure wound therapy for traumatic soft tissue defects by vacuum-assised closure (V.A.C.(R)). MATERIALS AND METHODS: 33 patients with traumatic soft tissue defects were treated by using V.A.C.(R) which removes edema fluid, eliminates an extrinsic cause of microcirculatory embarrassment and may directly stimulate cellular proliferation of reparative granulation tissue. We removed all necrotic tissue prior to application of the V.A.C.(R). The foam dressing was placed into direct contact with wound and was changed every 48~72 hours. The setting for vacuum pump was continuous pressure of 100 to 125 mm Hg. C-reactive protein was checked to evaluate wound infection. We measured wound size and total duration of treatment. RESULTS: Mean duration of treatment was 25.2 days and mean decrease of wound size was 31.9%. The concentration of CRP after V.A.C.(R) therapy reduced by day 8 below 1.0 mg/dl and gradually decreased to normal level by day 10. All patients showed hastened wound healing by rapid formation of granulation tissue. CONCLUSION: Negative pressure wound therapy is useful in patients with traumatic soft tissue defects, which reduces treatment duration and cost by rapid wound healing and effective infection control.

Comparison of High Tibial Osteotomy: Opening versus Closing Wedge Osteotomy / 대한정형외과학회잡지

PURPOSE: To evaluate the clinical and radiological results of an opening wedge osteotomy for an osteoarthritic knee, and compared these results with those of a closing wedge osteotomy. MATERIALS AND METHODS: The study included 27 patients (29 cases) with an opening wedge osteotomy (Group A) and 30 patients (30 cases) with a closing wedge osteotomy (Group B). The radiological results obtained regarding the degree of osteoarthritis, femur-tibia angle, tibial alignment, posterior tibial slope and patellar height using the Insall-Salvati's method were analyzed. HSS score was used for evaluation of the clinical results. RESULTS: Preoperatively, there were no significant differences between the two groups regarding the degree of osteoarthritis, the femur-tibia angle, tibial alignment, posterior tibial slope, and patellar height. Two years after surgery, the femur-tibia angle and tibial alignment were significantly improved to 7.7degrees valgus and 1.3degrees valgus, respectively, and the patellar height was not changed significantly in group A. Similar degrees RESULTs were obtained in group B. The tibial posterior slope increased from 3degrees to 10.7degrees in group A and decreased from 4degrees to 3.7degrees in group B. Clinically, the HSS score was improved from 74 points preoperatively to 93 points 2 years postoperatively in the opening group, and was similar to the improvement observed in the closing group. The complications included 1 delayed union in the opening group, and 3 cases of superficial peroneal nerve palsy and 1 delayed union in the closing group. CONCLUSION: An opening wedge osteotomy is a relatively simple and safe procedure that gives similar radiological and clinical outcomes to a closing wedge osteotomy, without peroneal nerve palsy. However, surgeons should take care in preventing an increase in the tibial posterior slope.
