The goal of the treatment of femoral neck fractures is early ambulation to prevent the complications such as pneumoniae or atelectasis, deep vein thrombosis, pulmonary embolism, bed sore, general weakness. The authors have tried to asess the outcome and complication of multiple pinning (28 cases) and biploar endoprosthesis (35 cases) for femoral neck fractures in average 18 momths with the range of 12 months to 5 years from May 1990 to May 1996. The results were asessed by interval from injury to operation, post operative complication and mortality rate, weight bearing time, Lunceford hip grading method.
The results were as folllows: 1. Post operative complications rate were 43% in multiple pinning, and 26% in bipolar group.
2. The mortality rate was 14.2% in multiple pinning group and 11.4% in bipolar endoprosthesis group. 3. The functional results evaluated by Lunceford's methods were satisfactory in 64% of multiple pinning group and 71% in bipolar endoprosthesis group. We concluded that displaced fractures, subcapital fracture, severe osteoporosis, old fracture over 3 weeks in elderly patients, bipolar endoprosthesis gave a more reliable results.
Twenty one comminuted fractures of the proximal tibia in 21 patients were treated with Ilizarov external fixator from May 1990 to May 1996 in Pusan City Medical Center. The average duration of external fixation was 17weeks, and all of the fractures healed without bone graft. The mean time to union was 18weeks in closed comminuted fractures, and 21 weeks in Gustilo type I, II open fractures. The complications with this technique were pin tract infection 3 cases, pin loosening 6 cases, septic arthritis 1 case, post-traumatic osteoathritis 1 case, and joint ankylosis 1 case. The average duration of follow up was 18 months. The range of knee motion of 19 cases of the the 21 patients was at least 115-degrees arc. Post-operative immediate exercise was possible, and partial weight bearing with crutch was also possible after post-operative 4 weeks. We concluded that Ilizarov external fixation is a satisfactory technique for the treatment of selected comminuted fractures of the proximal tibia.
The incidence of intertrochanteric fracture of the femur appears to be increasing, Particularly the more unstable comminuted fracture types are increasing, paralleling increased longevity in the population.
Fourteen cases were treated with primary bipolar hemiarthroplasty and eighteen cases were treated with compression hip screw at the Department of Orthopaedic Surgery of Pusan City Medical Center from June 1991. to June 1993. The results obtained were as follows; 1. In the bipolar hemiarthroplasty group, rehabilitation was easier and faster, and the incidences of pressure sore, pulmonary infection & atelectasis were significantly lower.
2. The early walking with full weight bearing that the bipolar hemiarthroplasty made possible is considered to be a major contributing factor to those results.
