Abstract

We reviewed retrospectively the results of stabilization of femoral neck fracture using multiple cannulated screws, in 20 patients who were treated at the department of Orthopaedic Surgery, Kangnam Sacred Heart Hospital from January 1991 through July 1995. With the average follow up of 2 years (from 1 year to 4.5 years), we analyzed these patients with the adequacy of reduction by Garden's alignment index and the functional results of the hip by the Lunceford method. The mean age of patients was 70 years (ranged from 34 to 88 years). The types of fracture according to Garden's classification were fifteen cases of Garden stage I or II, and five cases of Garden stage III or IV. The average interval from injury to operation was four days, ranging from I to 14 days. The adequacy of reduction by Garden's alignment index were as follows: anatomic in 8, acceptable in 10 and poor in 2 cases. According to the Lunceford method, the functional results were as follows: excellent in II, good in 6, fair in 1 and poor in 2 cases, respectively. We found that good result out of the femoral neck fractures, especially for stage I and II with the anatomical and acceptable reduction, can be expected by multiple cannulated screw fixation and early ambulation as possible.
