“…In order to obtain more evidence about this problem, we reviewed the retrospective cohort studies, Study or Subgroup although it was considered associated with high risk of bias. Nine retrospective cohort studies published in English were searched, of which eight reported better functional results in patients treated with cemented hemiarthroplasty [1][2][3][4][5][35][36][37], one reported there was no significant difference between the two groups [7]. The published retrospective cohort studies confirmed the theory that a painless hip was associated with higher mobility.…”

“…The question of whether the prosthesis should be cemented is widely debated but as yet unresolved. Some retrospective studies supported the use of cemented prosthesis for the treatment of femoral neck fracture in the elderly, the claimed advantages being little thigh pain and better mobility, with a lower frequency of prosthetic dislocation [1][2][3][4][5]. Other studies favoring uncemented prosthesis as the operative time, blood loss and incidence of perioperative mortality are less [6][7][8].…”

The purpose of this review was to assess the effectiveness and safety of cemented versus uncemented hemiarthroplasty for displaced femoral neck fractures in older patients. We searched the Cochrane Library, MEDLINE and EMBASE for published randomized clinical trials comparing cemented with uncemented hemiarthroplasty for femoral neck fractures. Eight trials assessing 1,175 hips were eligible for meta-analysis. The pooled results showed that there was no significant difference between cemented and uncemented group with regard to the mortality, reoperation rates and postoperational complications. The overall incidence of residual pain at 1 year after operation was 23.6% in the cemented prosthesis and 34.4% in the uncemented, with significant difference (relative risk 0.69, 95% CI 0.53-0.90; P = 0.007; fixed-effect models).The available evidence suggested that compared with uncemented hemiarthroplasty, cemented hemiarthroplasty in treating the elderly with displaced femoral neck fractures was not associated with a higher risk of mortality, reoperation and complications but can reduce the risk of residual pain and provide better functional results.

“…In this study, the Merle d' Aubigne total hip index was significantly higher for patients with cemented hemiarthroplasty, due mainly to less pain and better gait function. Anderson et al [40] Branfoot et al [41] and Singh et al [42] performed randomized studies to compare outcome of cemented versus uncemented Thompson prosthesis and they reported significantly more pain in the uncemented group. Emery et al [33], on comparing cemented Thompson and uncemented Moore stems also found better pain scores with the cemented prosthesis.…”

“…The Austin Moore prosthesis (AMP) is an uncemented unipolar hemiarthroplasty still widely used for displaced femoral neck fractures despite several studies demonstrating more favourable outcomes from cemented hemiarthroplasties [3,4]. Its use is generally reserved for frail low-demand elderly patients and those with medical conditions where a short procedure may be beneficial in patients that may be at increased cardiovascular risk from cementing [5].…”

“…Femoral loosening of the AMP is a well-documented complication [4,5]. A study by Yau et al demonstrated that early femoral loosening may be more likely to occur if the stem of the prosthesis did not occupy 70% of the core width of the femoral metaphysic [6].…”

Purpose It has previously been suggested that failure to achieve 70% metaphyseal fit with the Austin Moore prosthesis predisposes to subsidence and failure of the prosthesis secondary to stem loosening. We performed a radiological review to test this hypothesis, and determine whether a correlation existed between head size and metaphyseal fit of the uncemented Austin Moore hip prosthesis. Methods Post-operative radiographs of 102 uncemented Austin Moore hemiarthroplasty patients were retrospectively reviewed. Three observers blinded to the head size of the prosthesis, measured the percentage metaphyseal fit of each stem, using a previously published technique. Results Eighty-six females and 16 males were included in this study. Eighteen of the radiographs were excluded for incorrect implantation, narrow stem insertion, and un-interpretable post-operative radiographs. Implants with a head size of 42 mm had an average metaphyseal fit of 84.5%. Those with head size 54 mm had only a 56% metaphyseal fit. The result was strongly associated with an R value of −0.93. Conclusion We have shown an inverse correlation exists between prosthesis head size and metaphyseal fit. Austin Moore prostheses with head sizes greater than 49 mm are likely to be loose from the moment of insertion. This poses a particular risk in men. In our study, only one male required prosthesis with a head less than 49 mm. In these patients, use of an alternative prosthesis such as a bipolar uncemented or cemented hemiarthroplasty is recommended.
