28mm Head in Ceramic/Ceramic Total Hip Replacement
Our experience with alumina bearing and 28 mm head (at mean F.U. of 3.2 yrs) revealed excellent radiographic and clinical results. Patients were pain free in 98.65% (no cases showed groin or thigh pain), with satisfaction rate of 99.38%. No mechanical failure or alumina fractures were observed in our study.
Joint dislocation occurred in 1.22% of our patients. These results are superimposable to the dislocation rates observed with large heads employment. We are in agreement with the literature and state that adequate preoperative planning, proper surgical technique and restoration of hip biomechanics are the pillars for good long term results.
