OBJECTIVETo analysis the outcome of modified closure bone setting manipulation for the treatment of femoral neck fracture.

METHODSFrom January 2012 to December 2012, 47 cases of femoral neck fracture were treated and included 25 males and 22 females with an average age of (44.58±10.32) years old ranging from 23 to 61 years old. All patients had a history of trauma, hip pain and movement limited, limb shortening extorsion deformity, X-ray showed fracture between femoral head and femoral neck basic. Among them, 32 cases were Garden type III and 15 cases were type IV. Patients were performed surgical treatment at 2 to 5 days after admission with 45 degrees abduction and extension position, internal rotation reduction, and 3 guide pins were inverted in a equilateral triangular structure of upside down arrangement. The postoperative recovery quality, fracture healing, femoral head necrosis and hip function were observed.

RESULTSOperation time was 40 to 70 min, intraoperative bleeding was 20 to 50 ml. All patients received good reposition, and the intraoperative perspective was 12 to 25 times. Forty-five patients were followed up for 24 to 36 months, and 2 cases were lost. Fracture of 45 cases were got bony healing, 3 cases with partial necrosis of femoral head, both in the ARCO stage II. Twenty-four months after operation, Harris hip function score was 43.24±2.74 in pain, 42.82±1.95 in function, 3.72±0.45 in deformity, 2.77±0.52 in activity, 92.56±4.42 in total;the outcome was excellent in 39 cases, good in 4 cases, fair in 2 cases, without unbroken nails, infection, deep venous thrombosis, fracture and other complications.

CONCLUSIONSTreatment of femoral neck fracture with the modified bone setting manipulation has an advantages of good effect, postoperative hip function recovery, curative effect.
