Park, Baek, and Han: Treatment of Femoral Neck Fracture with Multiple Pinning


The incidence of femoral neck fracture is increasing because of the lengthening of human life span and a rising incidence of industrial trauma. Despite of the advance in treatment, femoral neck fracture presents poor prognosis and high rate of complications such as avascular necrosis or non- union due to anatomical consideration. It still remains one of the unsolved fracture as far as treatments and results are concerned. The purpose of this paper is to study the clinical results and factors predisposing to complication after multiple pin pixation of femoral neck fracture. The authors reviewed 50 cases of femoral neck fracture treated by multiple pin fixation at the Department of Orthopedic Surgery, Korea University Hospital from January 1989 to December 1996 with followed up period of more than 1 year and analyzed the relationship between the clinical results and age, degree of displacement, degree of osteoporosis, interval between onset of injury and operation, reducibility and complications. The results obtained were as follows: 1. The functional results by Lunceford criteria were excellent in 15 cases (30%), good in 13 cases(26%), fair in 9 cases(18%), and poor in 13 cases(26%) 2. Union occurred in 36 cases (72%) and the mean duration of union was 6.1 months. 3. There were 12 cases (24%) of avascular necrosis, 2 cases(4%) of non- union, 2 cases (4%) of malunion and 1 case of traumatic osteoarthritis. 4. Poor results were noted in cases of displaced fracture, osteoporotic bone under the Singh index 3, reduced in varus or valgus. Above results suggest that there was a relationship between the prognosis and bone density, degree of displacement and type of reduction, but the interval between the onset and operation within one month, and age distribution did not influence the end result.
