Abstract

BACKGROUND:

As a test indicator of total hip arthroplasty (THA), femoral offset plays an important role in the efficiency of THA and the life expectancy of prosthesis.

OBJECTIVE:

To investigate the correlation between the femoral offset and the postoperative complications of THA.

METHODS:

The femoral offset between healthy side and affected side of patients with femoral neck fracture after THA was compared. Totally 61 patients who were treated with THA after femoral neck fracture were followed-up. According to the difference of femoral offset between the healthy and affected sides, cases were divided into D > 4 mm group (difference > 4 mm) and D≤4 mm group (difference ≤ 4 mm).

RESULTS AND CONCLUSION:

Totally 31 cases were in the D > 4 mm group: the complications of pain, dislocation, claudication and lower limb length discrepancy were 4, 0, 2 and 6 cases, respectively. And 30 cases were in the D≤4 mm group: the complications of pain, dislocation, claudication and lower limb length discrepancy were 1, 0, 0 and 1 case, respectively. There is a close relationship between the effective reconstruction of femoral offset and complications after THA, and a good recovery of femoral offset can significantly reduce the occurrence of related complications after THA.
