ABSTRACT

INTRODUCTION: Hemiarthroplasty is the recommended treatment for displaced, intracapsular, femoral neck fractures. This study aimed to evaluate the early complications following insertion of the JRI Furlong cemented hemiarthroplasty, a contemporary, modular, double tapered, polished prosthesis. METHOD: A series of 459 consecutive patients (May 2006 - June 2009) treated with a JRI hemiarthroplasty with a minimum of one-year (1-4years) follow-up were evaluated. Data collected retrospectively from clinical records and hospital databases included patient demographics, mortality, deep infection, dislocation, periprosthetic fracture, and any requirement for revision or complications related to the prosthesis. RESULTS: Full data were available for 429 of 459 (93%), partial data for 30 (7%). Average age was 83 years (52-100), 76% were female. One-year mortality was 24%. Intraoperative fractures occurred in 17 patients (3.7%). There were two intraoperative deaths. There were nine early deep wound infections (2%). There were two revisions to total hip replacement (THR), four patients required conversion to THR and one underwent an excision arthroplasty procedure. DISCUSSION: Early surgical outcomes for the JRI hemiarthroplasty prosthesis are equivalent or superior to other major hemiarthroplasty prostheses previously reported however, there was a high intraoperative fracture rate of 3.7%. We recommend using a stem one size smaller than the final broach in fragile, osteoporotic bone. No patients re-presented with aseptic loosening or stem failure.

ABSTRACT

The aim of the present study was to assess the reliability of commonly used intra-articular calcaneal fracture classification systems and to compare them with the newer AO Integral Classification of Injuries (ICI) system. Forty computed tomography and radiographic images of 40 intra-articular calcaneal fractures were reviewed independently by 3 reviewers on 2 separate occasions and classified according to the Essex-Lopresti, Atkins, Zwipp and Tscherne, Sanders, and AO-ICI classification systems. The reviewers were unaware of the patients' identity and all aspects of clinical care. The data were analyzed using kappa (κ) statistics to assess the intra- and interobserver reliability. The κ values were calculated for Essex-Lopresti (κ = 0.85 intraobserver, κ = 0.78 interobserver), Atkins (κ = 0.42 intraobserver, κ = 0.73 interobserver), Zwipp and Tscherne (κ = 0.40 intraobserver, κ = 0.47 interobserver), Sanders (κ = 0.31 intraobserver, κ = 0.35 interobserver), and AO-ICI (κ = 0.41 intraobserver, κ = 0.33 interobserver). The AO-ICI classification system had levels of reproducibility similar to that of the Sanders classification, currently the most widely used system. The Essex-Lopresti classification demonstrated improved reliability compared with that reported in previous studies. This can be attributed to using sagittal computed tomography images, in addition to the originally described plain radiographs, for assessment. This improvement is relevant because of its accepted prognostic predictability.
