A Large-Scale Fifteen-Year Minimum Survivorship of a Cementless Triple Tapered Femoral Stem
© 2020 Elsevier Inc. Background: This study reports the long-term outcomes of a metaphyseal fit-and-fill cementless femoral component in total hip arthroplasty (THA) with a follow-up of 15-19 years. Methods: We conducted a retrospective review of 376 consecutive THAs (345 patients), using a triple tapered stem performed between 2000 and 2003 with a view to assessing survivorship and radiological and functional outcomes. Images were assessed for initial alignment, terminal osteolysis, or subsidence, while clinical outcomes were assessed using the St Michael\u27s Hip Score. Results: Forty-five (11.9%) hips were lost to follow-up, 20 (5.31%) had died before our 15-year cutoff follow-up, and 4 (1.06%) had declined follow-up early on, leaving 307 hips (81.64%, 276 patients) available for both clinical and radiological follow-up at a minimum of 15 years (range 15-19). The mean age at the time of operation was 49.6 years (range 19-71) and the cohort included 131 (42.67%) male and 145 (47.23%) female patients. Seven stems (2.28%) were revised: 4 due to periprosthetic fractures, 2 for periprosthetic joint infection, and 1 for adverse reaction to metal debris at the trunnion. The St Michael\u27s Hip Score improved from 14.2 (range 9-23) preoperatively to 22.3 (range 13 to 25) at the last documented follow-up (P = .000). Kaplan-Meier survivorship with stem revision for any reason as the end point was 97.70%. Worst-case scenario Kaplan-Meier survivorship, where all lost to follow-up are considered as failures, was 85.3%. No stem was revised for aseptic loosening. Conclusion: This triple tapered stem in THA shows excellent survivorship beyond a minimum of 15 years
Two-level reconstruction of isolated fracture of the lesser tuberosity of the humerus
Fractures of the lesser tuberosity of the humerus are typically met in
combination with other injuries of the shoulder. Case reports of
isolated lesser tuberosity fractures are particularly rare and,
consequently, therapeutic protocols have not yet been completely
clarified. Conservative as well as surgical treatment has been
recommended, while several operative techniques have been applied. We
present a case of a 39-year-old man with an isolated lesser tuberosity
fracture who was treated surgically in our institution. Due to fracture
comminution, a two-level reconstruction technique with headless screws
and buttress plate was applied. As far as we know, this method of
fixation of this type of fracture has not been previously described in
the literature. The patient tolerated the procedure well and excellent
results were obtained at the latest follow-up. (c) 2014 Baishideng
