Composite Reconstruction of the Hip Following Resection of Periacetabular Tumors: Middle-Term Outcome

The records of 18 patients with periacetabular tumors who underwent composite reconstruction of the hip following resection of periacetabular tumors were analyzed retrospectively. The mean follow-up period was 49.4 months (range, 28-100 months). During follow-up, 3 patients died and one had recurrence. Fifteen patients achieved favorable walking function; 8 had normal hip function and 7 had partial recovery of flexion function of the hip. The mean MSTS rating for hip function was 76.9%. Two patients had common peroneal nerve injury which was resolved in one of them. Middle-term follow-up showed that composite reconstruction of the hip following resection of periacetabular tumors can effectively remove tumors and provide favorable hip function for these patients. This approach is simple and less costly, and can be widely used.
