The increasing prevalence of osteoporosis in an ageing population has contributed to older patients becoming the fastest-growing group presenting with acetabular fractures. We performed a systematic review of the literature involving a number of databases to identify studies that included the treatment outcome of acetabular fractures in patients aged > 55 years. An initial search identified 61 studies; after exclusion by two independent reviewers, 15 studies were considered to meet the inclusion criteria. All were case series. The mean Coleman score for methodological quality assessment was 37 (25 to 49). There were 415 fractures in 414 patients. Pooled analysis revealed a mean age of 71.8 years (55 to 96) and a mean follow-up of 47.3 months (1 to 210). In seven studies the results of open reduction and internal fixation (ORIF) were presented: this was combined with simultaneous hip replacement (THR) in four, and one study had a mixture of these strategies. The results of percutaneous fixation were presented in two studies, and a single study revealed the results of non-operative treatment. With fixation of the fracture, the overall mean rate of conversion to THR was 23.1% (0% to 45.5%). The mean rate of non-fatal complications was 39.8% (0% to 64%), and the mean mortality rate was 19.1% (5% to 50%) at a mean of 64 months (95% confidence interval 59.4 to 68.6; range 12 to 143). Further data dealing with the classification of the fracture, the surgical approach used, operative time, blood loss, functional and radiological outcomes were also analysed. This study highlights that, of the many forms of treatment available for this group of patients, there is a trend to higher complication rates and the need for further surgery compared with the results of the treatment of acetabular fractures in younger patients.
There are a number of challenges associated with the operative treatment of acetabular fractures. The approach used is often extensive, while operative time and perioperative blood loss can also be significant. With the proliferation of 3D printer technology, we present a fast and economical way to aid the operative planning of complex fractures. We used augmented stereoscopic 3D CT reconstructions to allow for an appreciation of the normal 3D anatomy of the pelvis on the fractured side and to use the models for subsequent intraoperative contouring of pelvic reconstruction plates. This leads to a reduction in the associated soft tissue trauma, reduced intraoperative time and blood loss, minimal handling of the plate, and reduced fluoroscopic screening times. We feel that the use of this technology to customize implants, plates, and the operative procedure to a patient's unique anatomy can only lead to improved outcomes.
The inherent challenges of total hip replacement (THR) in children include the choice of implant for the often atypical anatomical morphology, its fixation to an immature growing skeleton and the bearing surface employed to achieve a successful long-term result. We report the medium-term results of 52 consecutive uncemented THRs undertaken in 35 paediatric patients with juvenile idiopathic arthritis. The mean age at the time of surgery was 14.4 years (10 to 16). The median follow-up was 10.5 years (6 to 15). During the study period 13 THRs underwent revision surgery. With revision as an endpoint, subgroup analysis revealed 100% survival of the 23 ceramic-on-ceramic THRs and 55% (16 of 29) of the metal- or ceramic-on-polyethylene. This resulted in 94% (95% CI 77.8 to 98.4) survivorship of the femoral component and 62% (95% CI 41.0 to 78.0) of the acetabular component. Revision of the acetabular component for wear and osteolysis were the most common reasons for failure accounting for 11 of the 13 revisions. The success seen in patients with a ceramic-on-ceramic articulation seems to indicate that this implant strategy has the potential to make a major difference to the long-term outcome in this difficult group of patients.
The introduction of the CPP significantly improved compliance of hand decontamination, correct usage of gloves and aprons, and overall infection-control in a large teaching hospital. The CPP is a highly effective auditing and educational tool that can be readily adapted for use in hospitals globally to monitor and improve infection-control practices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
