BACKGROUND: Operative treatment of acetabular fractures generally yields good results, but several authors report up to 15-20% of patients developing post-traumatic osteoarthritis (OA). Previous studies have shown that total hip arthroplasty (THA) following post-traumatic OA have inferior results compared to THA for primary OA. The aim of this study was to report on long-term outcome of THA following acetabular fracture, compared to primary OA. MATERIALS AND METHODS: We performed a matched cohort study with data from the Norwegian Arthroplasty Register (NAR)...

BACKGROUND: Modular femoral stems have the advantage of anatomic hip reconstruction by restoring the femoral offset thus minimising the bearing surface wear, implant loosening and dislocation. AIM: This study aims to investigate the existing literature on modular neck fractures, to identify predisposing factors and guide the decision-making process in the management of these difficult cases. METHODS: A systematic literature review was conducted until July 2022...

BACKGROUND: The use of larger femoral heads in total hip replacement (THR) has increased over the last decade. While the relationship between increasing head size and increased stability is well known, the risk of revision with increasing head size remains poorly understood. The aim of this study was to compare the outcome of total hip joint replacement with 32-mm and 36-mm heads. METHODS: We carried out a 20-year retrospective analysis of prospective data from the New Zealand Joint Registry (NZJR)...

INTRODUCTION: The purpose of this study was to analyse the robustness of comparative research that evaluated arthroscopic labral reconstruction versus other surgical management of labral pathology. Key measures of statistical fragility include the fragility index and fragility quotient.ß. METHODS: 12 comparative studies that evaluated the use of arthroscopic labral reconstruction were included in this study. Particular attention was placed on evaluating trends, either statistically significant or not, of functional improvement, complication rates, need for total hip arthroplasty (THA) and revision rates with associated p -values...

BACKGROUND: The choice between total hip arthroplasty (THA) and hemiarthroplasty (HA) to treat displaced femoral neck fractures, particularly among the elderly, is still controversial. Acetabular erosion consists of a late multifactorial process that may happen after hip HA resulting in significant postoperative burden. This study aims to investigate the impact of acetabular erosion progress after hip HA in patients over 70 years old. MATERIALS AND METHODS: This is a 5-year (2013-2018) retrospective study including consecutive series of patients >70 years who were treated with bipolar hip HA for femoral neck fractures...

BACKGROUND: Hip dysplasia can lead to pain and dysfunction in the young adult. Acetabular undercoverage leads to abnormal joint loading and results in joint degeneration, accelerating need for arthroplasty in this patient population. Conceptually, treatment focuses on increasing acetabular coverage in the form of periacetabular osteotomy. The procedure can be performed through the iliofemoral approach, and performing an anterior superior iliac spine (ASIS) osteotomy can enhance the visualisation in this approach...

BACKGROUND: Persisting groin pain post total hip arthroplasty (THA) is a common and complex issue that can be difficult to diagnose and manage. Acetabular component positioning is often implicated. AIMS AND METHODS: We used a previously well described and validated functional positioning protocol to determine if functional acetabular malpositioning was a factor in groin pain post THA and hence to determine if acetabular revision would be indicated. We compared patient-specific functional acetabular positioning to traditional CT evaluation of cup position and assessment of anterior cup overhang...

BACKGROUND: The Hueter-Anterior Approach (HAA) with its limited soft tissue and internervous dissection has been shown to be an effective approach for primary total hip and hip resurfacing arthroplasty (HRA). The purpose of this study is to evaluate the clinical outcome of patients requiring revision of HRA to total hip replacement using the HAA, assessing function and complications. METHODS: We performed a retrospective review of a prospectively maintained research database...

BACKGROUND: Despite the overall success of THA, between 5 and 20% report unsatisfactory results. Several factors may cause this variable outcome. 1 of them might be ethnicity which, because of its potential social impact on living conditions, may influence quality of life too. It should be studied whether patients born and being operated in their home country Bosnia and Herzegovina (BH) had similar results as immigrants being operated in Sweden (IS). METHODS: Data of 280 patients were collected prospectively from questionnaires in the BH group...

BACKGROUND: Prolonged operative time is a risk factor for increased morbidity and mortality after open reduction and internal fixation (ORIF) of hip fractures. However, the quantitative nature of such association, including graduated risk levels, has yet to be described. This study outlines the graduated associations between operative time and (1) healthcare utilisation, and (2) 30-day complications after ORIF of hip fractures. METHODS: The National Surgical Quality Improvement Program (NSQIP) database was queried (January 2016-December 2019) for all patients who underwent ORIF of hip fractures ( n  = 35,710)...

BACKGROUND: Corrosion at the head-neck junction of femoral stems is a rare complication of total hip arthroplasty (THA) with manifestations ranging from subclinical wear to failure. Prior studies have identified a single femoral component design with an increased propensity for catastrophic trunnion failure. The purpose of the present study was to quantify trunnion damage of this femoral component retrieved from patients undergoing revision THA for non-trunnionosis indications. METHODS: 24 femoral components from a single manufacturer were identified for study inclusion...

INTRODUCTION: The purpose of this study was to determine whether there have been changes in the numbers and complexity of femoral fragility fractures presenting to our department over a period of 10 years. METHODS: Patients >60 years presenting with femoral fragility fractures to our institution in 2018-2019 (397 fractures) were compared with respect to demographic data, incidence rates, fracture classification and surgical management with a historical cohort from 2009-2010 (335 fractures)...

INTRODUCTION: The most effective surgical approach for total hip arthroplasty (THA) remains controversial. Comparisons of surgical approach based on patient-reported outcome measures (PROMs) have been limited to short- to mid-term outcomes or the comparison of only 2 approaches. The aim of this study was to compare PROMs for the 3 main approaches for THA with up to 10 years follow-up. METHODS: A total of 906 patients who underwent primary THA at a single hospital between 2009 and 2020 through an anterior (312), lateral (211) or posterior (383) approach were evaluated using the Oxford Hip Score (OHS), EuroQoL-5-Dimension (EQ-5D-5L) and visual analogue scale/verbal rating scale for pain (VAS/VRS)...

BACKGROUND: The primary purpose of this retrospective case series was to describe the prevalence and outcomes of single-stage hip arthroplasty in patients who were previously treated for septic arthritis of the native hip at our institution over a 20-year period. This study also examined rates of persistent or recurrent infection, reoperation, and mortality for septic arthritis of the native hip. METHODS: Adult patients treated for septic arthritis of the native hip at our institution from 1995 to 2015 were retrospectively identified...

INTRODUCTION: Disproportionate emphasis has been attributed to hip fracture over other femoral fractures through implementation of Best Practice Tariff (BPT).This retrospective comparative observational cohort study aimed to evaluate the epidemiology of native and periprosthetic femoral fractures and establish any disparities in their management relative to hip fractures. METHODS: All patients ⩾60 years admitted with a native or periprosthetic femoral fracture during July 2016-June 2018 were identified using our hospital database...

BACKGROUND: Although several reports have examined the association between preoperative function and postoperative outcomes in patients undergoing total hip arthroplasty (THA), it is unclear whether the ability of the affected or non-affected side particularly impacts on outcomes. We aimed to investigate the association between affected and non-affected side ability and walking independence. METHODS: We prospectively enrolled 721 consecutive patients who underwent THA...

BACKGROUND: Improvements in outcomes following hip and knee revision arthroplasties have been demonstrated following the introduction of specialised orthopaedic services in the form of 'hub and spoke' networking models. In light of the COVID-19 pandemic, these networks have undergone some inevitable adaptations. We investigated the impact of recent adaptations on the performance of our regional revision arthroplasty network. METHODS: A retrospective review of all referrals that were discussed at our regional revision arthroplasty meeting, over 2 separate phases, was undertaken...

AIMS: This study reports on the Exeter-Trident total hip arthroplasty (THA) using an alumina ceramic-on-ceramic bearing with 10-year clinical and radiographic follow-up. PATIENTS AND METHODS: Between January 2001 and January 2006, 275 THAs were performed. Mean age at surgery was 52.7 (17-86) years, with 84 patients (33.6%) aged <50 years. The primary outcome was all-cause construct survival at minimum 10 years. Secondary outcomes included functional and noise scores...

Acetabular augmentation is a challenge for complex primary and revision hip surgery. Several methods exist to recreate a supportive, hemispherical acetabulum where a defect exists, however, these can be complex, expensive, time consuming, and limited by available size and shape. We present a simple, inexpensive, quick and customisable method of acetabular augmentation using cementless polyethylene with titanium coating. The first case is presented with follow-up up to 8 years.

INTRODUCTION: The aim of this study was to design and validate a predictive model for 30-day mortality in a cohort of patients from the Spanish National Hip Fracture Registry (RNFC) with variables collected at the Emergency Department. METHODS: Retrospective study of a prospective database of hip fracture patients ⩾75 years old between 1 January 2017 and 30 September 2019. Patient characteristics, type of fracture and osteoprotective medication were collected at the Emergency Department...
