Background: Arthroplasty is the treatment of choice for elderly patients with displaced femoral neck fractures. When compared to total hip arthroplasty (THA), higher revision rates have been reported for hemiarthroplasty (HA). Conversion of failed HA to THA can be complex, especially in the elderly population at risk for revision surgery complications. We report a single institution’s experience with conversion of failed HA to THA at mid-term follow-up. Methods: We identified patients converted from failed HA to THA from 2006 to 2016. Clinical data including indication for index and conversion surgery, maintenance or revision of femoral component during conversion, operative time, estimated blood loss, postoperative complications, and need for revision surgery were collected. Descriptive statistics were analysed in SPSS. Results: The cohort included 21 men and 39 women (mean age of 74.5 years). The mean follow-up after conversion HA to THA was 2.8 years. During conversion surgery, the femoral component was revised in 75.0% and retained in 25.0% of cases. After conversion HA to THA, the rate of major complications and re-revision at 2 years was 11.7% and 10.0%, respectively. Femoral revision versus retention did not affect complication rates (11.1% vs. 6.7%; p = 0.31) or re-revision rates (8.9% vs. 13.3%; p = 1.0). Conclusions: In this high-risk population, mid-term follow-up demonstrated tolerable complication and re-revision rates, the majority of which were for instability. We observed high rates of femoral component revision during conversion THA, although this did not increase the likelihood of postoperative complications or need for future surgery.

Background and Objective. Intracapsular fractures of the femoral neck account for a major share of fractures in the elderly. Open reduction and internal fixation has been shown to have a higher rate of revision surgery than arthroplasty. The aim of this study was to assess and compare the rates of revision surgery performed after internal fixation and primary total hip arthroplasty. Material and Methods. Between 2004 and 2006, 681 intracapsular femoral neck fractures in 679 consecutive patients were treated with internal fixation or total hip arthroplasty at our institution. Revision surgery rates were evaluated at 1-, 3-, 6-, 12-, and 24-month follow-up. Results. There was no significant difference in the ratio of internal fixation to total hip arthroplasty during 2004–2006 (P=0.31). The mean rate of total hip arthroplasty was 19.1% with a lower rate being among patients younger than 60 years. Revision surgery rates at the 2-year followup were higher in the internal fixation group compared with total hip arthroplasty group (28.9% vs. 7.0%, P<0.001). Patients who underwent internal fixation were at a 4-fold greater risk of having revision surgery at the 2-year follow-up than those who underwent total hip arthroplasty (odds ratio, 4.11; 95% CI, 1.95–8.65; P<0.001). Age was a significant risk factor for revision surgery after total hip arthroplasty (hazard ratio, 0.93; 95% CI, 0.87–0.98; P=0.02), but not significant after the internal fixation (P=0.86). Conclusions. Higher revision surgery rates after internal fixation favors arthroplasty as a primary choice of treatment for the femoral neck fractures.

Introduction: Longevity and success of total hip arthroplasty (THA) is largely dependent on component positioning. While use of robotic platforms can improve this positioning, published evidence on its clinical benefits is limited. Therefore, the aim of this study was to assess the clinical outcomes of THA with robotic surgical assistance. Materials and Methods: We conducted an analysis of robotic arm-assisted primary THAs performed by a single surgeon utilizing a posterior approach. A total of 99 patients (107 cases) who had a minimum two-year follow up were identified. Their mean age was 61 years (range, 33 to 84 years), and their mean body mass index was 30.5 kg/m2 (range, 18.5 to 49.1 kg/m2). There were 56% female patients and primary osteoarthritis was the principal hip diagnosis in 88.8%. Operative times, lengths of hospital stay, and discharge dispositions were recorded, along with any complications. Modified Harris Hip Scores (HHS) were calculated to quantify clinical outcomes. Results: Mean postoperative increases in HHS at 2- to 5.7-year follow up was 33 points (range, 6 to 77 points). There were no complications attributable to the use of robotic assistance. Surgical-site complications were rare; one case underwent a revision for prosthetic joint infection (0.93%) but there were no dislocations, periprosthetic fractures, or cases of mechanical implant loosening. There was no evidence of progressive radiolucencies or radiographic failure. Discussion: Robotic arm-assisted THA resulted in low complication rates at minimum two-year follow up, with clinical outcomes comparable to those reported with manual surgery.1–4 The haptically-guided acetabular bone preparation enabled reliable cementless acetabular fixation and there were no adverse events related to the use of the robot. Dislocations were avoided in this case series. Randomized controlled clinical trials are needed to compare manual to robotic surgery and to investigate whether the precision found with this functional planning will reliably reduce the incidence of dislocations.

Background: As the incidence of primary total hip arthroplasty (THA) continues to increase, revision THA (rTHA) is becoming an increasingly common procedure. rTHA is widely regarded as a more challenging procedure, with higher complication rates and increased medical, social and economic burdens when compared to its primary counterpart. Given the complexity of rTHA and the projected increase in incidence of these procedures, patient optimisation is becoming of interest to improve outcomes. Anaesthetic choice has been extensively studied in primary THA as a modifiable risk factor for postoperative outcomes, showing favourable results for neuraxial anaesthesia compared to general anaesthesia. The impact of anaesthetic choice in rTHA has not been studied previously. Methods: A retrospective study was performed using the American College of Surgeons National Surgical Quality Improvement Program database. Patients who underwent rTHA between 2014 and 2017 were divided into 3 anaesthesia cohorts: general anaesthesia, neuraxial anaesthesia, and combined general-regional (neuraxial and/or peripheral nerve block) anaesthesia. Univariate and multivariate analyses were used to analyse patient characteristics and 30-day postoperative outcomes. Bonferroni correction was applied for post-hoc analysis. Results: In total, 5759 patients were identified. Of these, 3551 (61.7%) patients underwent general anaesthesia, 1513 (26.3%) patients underwent neuraxial anaesthesia, and 695 (12.1%) patients underwent combined general-regional anaesthesia. On multivariate analysis, neuraxial anaesthesia was associated with decreased odds for any-one complication (OR 0.635; p  < 0.001), perioperative blood transfusion (OR 0.641; p  < 0.001), and extended length of stay (OR 0.005; p = 0.005) compared to general anaesthesia. Conclusions: Relative to those receiving general anaesthesia, patients undergoing neuraxial anaesthesia are at decreased risk for postoperative complications, perioperative blood transfusions, and extended length of stay. Prospective controlled trials should be conducted to verify these findings.

AbstractDislocation is among the most commonly reported complications following revision total hip arthroplasty. Dual-mobility bearings may lower the risk of dislocation. The authors report the results of a multicenter study evaluating the use of a dual-mobility acetabular cup design that was cemented into a metal shell as part of complex acetabular reconstructions or in cases where the risk of dislocation was felt to be high, such as isolated bearing exchanges. Eighteen patients were identified for being at high risk of dislocation who underwent cementation of a dual-mobility shell that is specifically made for cementation, into a fully porous metal revision acetabular cup (10 patients) or into a well-fixed cup at the time of revision without removal of the existing acetabular component (eight patients). Patients were assessed clinically and radiographically at a minimum of 2 years for the evidence of dislocation, revision surgery, and implant loosening. At a mean of 36 months (range, 25–56 months), one patient died and one was lost to follow-up. There were no known cases of hip dislocation. There was one repeat revision, for a deep infection treated with irrigation and debridement. The mean preoperative Harris Hip Score of 46 (range, 40–79) improved to a mean of 65 points (range, 41–97) at the most recent evaluation. Acetabular components were retained in 8 out of 18 cases and the dual-mobility shell was cemented into it. Cementation of a dual-mobility cup into a shell at the time of a revision surgery is a safe and reliable construct at minimum of 2 years for patients at high risk of dislocation. There were no complications related to the cementation of the cup into the metal shell. Longer follow-up is required to further assess the durability of this construct.
