Total hip replacement with a short cementless stem type 2B: Results of 2 to 5 years of follow-up
Abstract
Objectives: We sought to determine our 2 to 5-year survivorship, intraoperative fractures, subsidence and thigh pain rate in a consecutive, independent, one surgeon series of patients in whom a type-2B short stem was implanted.Patients and Methods: The first 100 type 2B consecutive short femoral stems implanted in 84 patients with a mean age of 47 years old were reviewed. Indications included age younger than 55 years (85 hips), or participation in impact sports in patients aging 56 to 60 years old (15 hips). Initial diagnosis was osteoarthritis in 82% of the cases. Median follow-up was 42 months.Results: Stem survival rate was 99% at 2 to 5 years for stem revision for any aseptic reason and 98% when infection was included. The mean Harris Hip Score improved significantly from 55 to 96 at final follow-up (p 0.02). There was one lateral cortex perforation, and three intraoperative calcar incomplete fractures (3%), only one of them required cerclage wiring and delayed weightbearing. No patient referred thigh pain at final follow-up. Only one case subsided 4 mm and then stabilized. The risk of revision was 1% at 2 to-5 years (95%CI 93.1-99.8%).Conclusions: Promising short-term results with this design were observed in this single surgeon, non-designerconsecutive series including the learning curve period using a type 2B short stem in young active patients, in which bone preservation is justified.Downloads
