OBJECTIVE: To evaluate the effectiveness of anatomic femoral component prosthesis for severe development dysplasia of the hip (DDH) in total hip arthroplasty (THA).
METHODS: Between September 2009 and September 2013, 48 patients (51 hips) with severe DDH underwent THA with cementless anatomic femoral component prosthesis. There were 5 males (5 hips) and 43 females (46 hips) with an average age of 51 years (range, 28-67 years). The left hip was involved in 25 cases, the right hip in 20 cases, and bilateral hips in 3 cases. There were 39 cases (44 hips) of Crowe type III and 9 cases (7 hips) of Crowe type IV. The visual analogue scale (VAS) score was 5.72 +/- 1.84, and Harris score was 41.66 +/- 4.87 at preoperation. All patients had leg discrepancy with a length difference of (4.31 +/- 0.84) cm.
RESULTS: The duration of surgery was 59-110 minutes (mean, 78.6 minutes), and the hospitalization days were 6-20 days (mean, 12.3 days). All patients obtained primary healing of incision without wound related complications of swelling, effusion, and infection. Two patients were found to have intramuscular venous thrombosis. All patients were followed up 10-54 months (mean, 29 months). Limp was observed at the early stage after operation in 9 patients and disappeared after 1 year, the other patients had normal gait. The VAS score 1.46?0.47, Harris score 88.66 +/- 3.48, and the leg length difference (1.15 +/- 0.33) cm at last follow-up all showed significant differences when compared with the preoperative values (P<0.05). No prosthesis loosening or subsidence, heterotopic ossification, dislocation, and infection occurred.
CONCLUSION: Anatomic femoral component prosthesis for severe DDH in THA can relieve pain, and improve the hip joint function and limb discrepancy. Short-term effectiveness was satisfactory, but the long-term effectiveness should still be observed in future.
