Abstract
AIM: Aim of the investigation was to identify prognostic factors predicting the level of postoperative function following Girdlestone ("G")-arthroplasty. METHODS: Data were derived from 87 patients, 90 hips, treated with "G"-arthroplasty at one institution between 1983 and 2000. RESULTS: Hip scores amounted to 38.7 (HHS) and 3.5 (Merle) points. The number of previously implanted total hip arthroplasties (THR) did not correlate with the functional result of "G"-arthroplasty (r = - 0.1400; p = 0.4524). On average, the duration of THR prior to "G"-arthroplasty was 44.6 months. Survival time of the latest THR and function of "G"-arthroplasty did not correlate (r = 0.0705; p = 0.7065). Patient age at primary THR, at follow-up, or at "G"-procedure did not correlate with HHS (r = - 0.0367, p = 0.8418, r = 0.1527, p = 0.4121; r = - 0.0151; p = 0.9356, respectively). Time following "G"-arthroplasty, averaging 90.6 months, did not correlate with patients function (r = 0.0920, p = 0.6289). Revision following "G"-procedure and the presence of diabetes positively correlated (p = 0.0104). The appearance of cement in the femoral canal and radiographic signs of persistent bone infection correlated significantly (p = 0.0572). CONCLUSION: Patient age, duration of "G"-hips, and number of prior THR were not reliable to predict the function of "G"-arthroplasty.
