Medium-Term Follow-Up of a Modular Tapered Noncemented Titanium Stem in Revision Total Hip Arthroplasty A Single-Surgeon Experience
We report a single-surgeon experience with a noncemented modular revision shaft (Modular Prosthesis; LINK, Hamburg, Germany) with clinical and radiographic results of 63 patients after 10 years. The Harris Hip Score improved from 51 to 84 points. Intraoperative complications included 11 fractures. Four patients had postoperative femoral fractures. Further shaft revisions were necessary: 1 subsidence, 1 late fracture, 1 late deep infection. Sixty-eight percent of cases showed revision defects as graded 3° by Mallory; 95 % did not show signs of loosening or subsidence; 38 patients showed adequate bone remodeling in the shaft and proximal femur; 21 patients showed excellent recovery of preoperative osteolytic areas, and 5 patients did not show signs of remodeling. The Modular Prosthesis stem shows adequate fixation and tendency toward satisfactory bone remodeling after 10 years.
