Aims. The Exeter femoral stem has a cemented, polished taper-slip design, and an excellent track record. The current range includes short-length options for various offsets, but less is known about the performance of these stems. The aim of this study was to compare the survival of short-length stems with standard-length Exeter stems. Methods. A systematic review of all studies reporting the use of short-length Exeter stems in primary total hip arthroplasty (THA) was undertaken. Survival data, the indication for revision, and patient-reported outcomes were gathered from observational and randomized studies. Studies based on registry data were analyzed separately. Results. The review included nine studies which covered a total of 2,190 short stems. The mean follow-up was 6.4 years (2 to 12) with an all-cause survival of 95.4%. When revisions due to aseptic acetabular loosening were excluded, the survival was 97.7%. Four stems fractured (0.18%). The mean Oxford Hip Score improved from 18.29 (1.33 to 21.6) preoperatively to 41.59 (32.9 to 43.4) at final follow-up. Three studies used data from national registries. A total of 25,895 short stems (offset ≤ 35.5 mm) were used compared with 336,218 standard-length stems. In these studies, short stems had a hazard ratio (HR) for all-cause survival of 1.19 (95% CI 0.96 to 1.43) with a rate of revision per 1,000 component-years of 0.037 compared with 0.035 for standard-length stems. One study from the New Zealand Joint Registry divided short stems into standard and small offset groups. Standard offset short stems (≥ 37.5 mm) had a 0.84 HR (95% CI 0.38 to 1.88) while small offset short stems (≤ 35.5 mm) had a 1.6 HR compared with standard stems (95% CI 1.3 to 1.98). Conclusion. Short Exeter stems perform well and are a safe femoral component in primary THA, according to the current literature. There does not appear to be an increased risk of implant fracture associated with these stems. Cite this article: Bone Joint J 2025;107-B(1):27–33

Aims

This meta-analysis and systematic review aimed to comprehensively investigate the effects of vitamin K supplementation on bone mineral density (BMD) at various sites and bone metabolism in middle-aged and older adults.

Aims

The aims of this systematic review were to assess the learning curve of semi-active robotic arm-assisted total hip arthroplasty (rTHA), and to compare the accuracy, patient-reported functional outcomes, complications, and survivorship between rTHA and manual total hip arthroplasty (mTHA).

Aims

Short-stemmed femoral implants have been used for total hip arthroplasty (THA) in young and active patients to conserve bone, provide physiological loading, and reduce the incidence of thigh pain. Only short- to mid-term results have been presented and there have been concerns regarding component malalignment, incorrect sizing, and subsidence. This systematic review reports clinical and radiological outcomes, complications, revision rates, and implant survival in THA using short-stemmed femoral components.
