Abstract
Aims: A retrospective study was done to examine the rate of failure. Methods: The most recent evaluation consisted of a medical papers and a radiographic examination.
Between 1992 and 2000 in general orthopaedic unit 222 patients with an acute femoral neck fracture were managed by 180 primary prosthetic replacements and 42 cannulated screws internal fixations (25 percutaneosly and 17 open technique).
The patients treated with cannulated screws had a mean age of 63,5 years (range,42 to 88 years) at the time of operation and were followed-up on average for 42 months (range, 12 to 102 months). There were 13 type B1 and 29 type B3 according to AO classification system. Results: Four patients had died early postoperatively (less than 6 months). Femoral neck fracture healed in 24 patients (57%).
Osteonecrosis developed in 5 patients (12%).
Redisplacement of the fracture and non-union were found in 16 patients (38%). Revision operation was done in 13 patients (10 total arthroplasties, 2 hemiar-throplasties and 1 corrective osteotomy). Conclusions: An acute subcapital desplaced fracture of the femoral neck still remains the so-colled “Unsolved fracture”.
