Treatment of Distal Tibial Metaphyseal Fracture Using MIPPO Technique / 대한족부족관절학회지

PURPOSE: To evaluate the results of MIPPO (minimal invasive percutaneous plate osteosynthesis) technique for distal tibial metaphyseal fractures. MATERIALS AND METHODS: It is a retrospective study of 13 patients who were treated by MIPPO technique for distal tibial metaphyseal fractures from Jan. 2001 to Jan. 2003. The average age was 46.7 years and mean follow-up period was 13.3 months. According to AO classification, there were 8 cases of A1, 3 cases of A2, 1 case of B1 and 1 case of C2. One case of A1 was a Gustilo-Anderson type I open fracture and fibular fractures were combined in 12 cases. We applied anatomical reduction and internal fixation for the fibular fractures and internal fixation on the medial side of the tibia by MIPPO technique for distal tibial metaphyseal fractures. Clinical results were evaluated using radiographic results, Neer score, the starting time of postoperative exercise and clinical complications. RESULTS: According to the Neer score, all cases showed satisfactory results. Active ankle ROM was started at average 2.4 weeks (2~4 weeks) and full weight bearing ambulation at average 5.2 weeks (4~8 weeks) postoperatively. Union of fractures was obtained by average 14.4 weeks (8~18 weeks) postoperatively. Two cases showed 5 degrees limitation of motion without functional deficits and other cases showed satisfactory ROM results. One case had 6 degrees valgus deformity without functional deficits. There were not any other complications like soft tissue problems and delayed-or non-union. CONCLUSION: MIPPO technique for the treatment of distal tibial metaphyseal fractures is a feasible technique with a good clinical outcomes.

Total Knee Arthroplasty in Stiff Knee

PURPOSE: To evaluate the results of TKRA (Total knee replacement arthroplasty)for the treatment of stiff knee. METHODS & MATERIALS: TKRA has been performed for 18 cases of stiff knee ( ROM < 50 degrees ) between January 1994 and December 2000. 16 cases which have been followed up for more than 2 years were analysed. Average follow-up was 3.3 years(2-6 years). 3 were male and 13 were female. The average age was 55.8 years(34-75years). Sequales of infection were most with 6 cases and followed by osteoarthritis (4 cases, 2 cases had been performed arthroscopic debridement) and rheumatoid arthritis (3 cases) and traumatic arthritis (3 cases) in order. TKRA was performed on average 12.2 years (1-40 years) after knee stiffness has been developed. We evaluate the results with ROM, HSS score and complications. RESULTS: Average ROM was increased from 31.6 degrees(0 degrees-50 degrees) preoperatively to 95.4 degrees(80 degrees-120 degrees) postoperatively. 5 degrees of flexion contracture was present in only 1 case. Average HSS score was improved from 59.6 points preoperatively to 84.6 points postoperatively. The patella tendon was partially ruptured in 1 case during surgery, but by brace application and rehabilitative exercise, ROM was improved to 90 degrees, 1 year post operatively. There were 1 superficial skin infection which was resolved by revision of wound and skin graft, and deep infection in 3 cases, which needed knee fusion finally. CONCLUSION: TKRA is a good method for improving function in knee stiffness although infection risk is high.
