Cementless, modular, distally fixed stem in hip revision arthroplasty: a single-center study of 132 consecutive hips

PURPOSE: The use of cementless, modular, distally fixed stem in hip revision arthroplasty has increased during the last decades. We aimed to analyze the early and late postoperative complications, re-operation rate, and survival rate of the MP stem operated at our county hospital with relatively lim...

description PURPOSE: The use of cementless, modular, distally fixed stem in hip revision arthroplasty has increased during the last decades. We aimed to analyze the early and late postoperative complications, re-operation rate, and survival rate of the MP stem operated at our county hospital with relatively limited caseload. METHODS: In this retrospective study, we included 132 hips operated with MP stem between January 2007–2014. An independent observer reviewed patients’ medical records in July 2015 (18–102 months postoperatively, median 52.5) to collect the following data: age, sex, American Society of Anesthesiologists (ASA) class, body mass index, indication of revision, type of operation, early and late complications, re-operation rate, and mortality during study period. RESULTS: The commonest indication for MP stem operation was aseptic loosening (72%). We found early and late postoperative complications in 29% of cases. The most common complication was prosthetic dislocation (8%), followed by intra-operative peri-prosthetic fracture (5%). The commonest indication for MP re-operation was soft tissue revision for infection (7%) followed by closed reduction for prosthetic dislocation (6%). We found no correlation between the age, sex, ASA class, and type of operation and the re-operation risk. Only one prosthesis was extracted giving a survival rate for 99% for the study period. CONCLUSION: This study showed good results of the MP prosthesis with reasonable complication and re-operation rates and negligible extraction rate, indicating the good performance of this implant even when used in the setting of a county hospital with limited caseload.
