Abstract:

BACKGROUND: More and more patients required total hip arthroplasty (THA) after hip fusion. However, due to apraxias of tissue with long-term, patients need reconstruct soft tissue tension during replacement to prevent dislocation of the prosthesis after replacement.
OBJECTIVE: To discussion the application of patch in the THA to reconstruct soft tissue tension after hip fusion.
METHODS: From January 2007 to January 2011, 21 patients with hip fusion were treated with the THA. Unequal length of lower extremities was corrected, muscle was unable to close after restoring the patient’s femoral offset. Patch was used for reconstructing soft tissue tension during the operation.
RESULTS AND CONCLUSION: At 1 year after operation, Harris was (83.8±6.4 score), flexion of hip activity was (79.5°±4.6°). Two patients still needed walking stick after the operation. Lumbago, side gonalgia and the opposite side hip pain before the operation were obviously alleviated, and only two patients still had leg length discrepancy. Over 5 years after the operation, nine patients were not found the loosed performance. The patch plays an important role in the soft tissue tension reconstruction and is very important to hip function recovery and prosthesis stability.
