OBJECTIVES: Traction force widens the joint space during hip arthroscopy. It is unclear how much the traction force varies and if it is related to the joint space widening. Main goal of our study was to measure the amount of force needed to widen the hip joint. Second goal was to study the relation between this force and the amount of joint space widening. METHODS: Traction force was measured in 27 patients (of whom 24 female, mean age 41) during arthroscopy. Measurements were performed before the procedure, after vacuum seal release and after capsulotomy...

BACKGROUND: This paper presents a parametric investigation into the effect of femoroacetabular impingement (FAI) and developmental dysplasia of the hip (DDH) on the sphericity of the femoral supra-equatorial region and acetabulum. METHODS: Radiographic parameters from x-rays, sphericity calculations and visualisation and joint contact area and pressure from FE models of 10 DDH, FAI and normal hips were analysed and compared both within and between hip groups. RESULTS: The sphericity of the acetabulum and femoral head of both the DDH and FAI groups was found to be less than that for normal hips but the variation in sphericity was greater (range 2...

INTRODUCTION: In arthroplasty surgery, positioning of the components must be accurate and reproducible to avoid complications. Conventional guides are often used to align a component, but they require surgical skill and experience, and are prone to error. To this end, a single-use, size-specific, nylon guide (single-use nylon guide) has been developed for the purpose of increasing the accuracy without adding extra cost to the operation. The effectiveness of this type of guide was evaluated in using a synthetic bone study...

BACKGROUND: Psychological distress is presumed to be an important factor that can adversely impact the outcome of orthopaedic procedures. The Distress and Risk Assessment Method (DRAM) is an evaluation tool which assesses psychological distress in patients with low back pain. The purpose of this prospective study was to assess the influence of preoperative psychological distress, as determined by the DRAM score, on the functional outcomes of total joint arthroplasty (TJA). MATERIALS AND METHODS: A prospective study of 61 TJAs was performed at a single institution...

BACKGROUND: While extreme elderly patients (age 80 and above) benefit from joint replacement, there is controversy about whether their physical function improves as much as younger individuals following total hip arthroplasty. METHODS: We completed a retrospective cohort study comparing extreme elderly total hip arthroplasty (THA) patients to younger patients. We obtained data from a large institutional repository of 2327 consecutive THAs performed from April 2011 through July 2016 at an American academic medical centre...

BACKGROUND: There is a trend for using jumbo cups/oblong devices for acetabular reconstruction as alternative to biological solutions. We report about a spectrum of reconstruction methods and their mid-term results. METHODS: Inclusion of 214 consecutive patients undergoing total hip arthroplasty revision surgery. Patients were examined using the Harris Hip Score (HHS). Based on the intraoperative acetabular defect situation, cases were classified into 1 of 5 possible categories of a stability classification for acetabular replacement (SCAR)...

INTRODUCTION: Breakage of the femoral stem component of a total hip replacement is now uncommon but continues to be seen with certain stem designs and in certain patient groups. Data previously published on this topic has been limited, either gathered from a single surgeon or centre, or included only a single stem design. METHODS: We reviewed the data from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR), identified and analysed 143 stem breakages over a period of 16 years, covering 44 different stem designs...

INTRODUCTION: Iliopsoas impingement occurs secondary to a tight iliopsoas tendon that causes impingement during movement. This review presents current aspects regarding the diagnosis of iliopsoas impingement and also exposes the readers to the possible anatomic and clinical variations together with the available treatment options. METHODS: We conducted a narrative literature review with regard to non-arthroplasty iliopsoas impingement. RESULTS: Iliopsoas impingement is characterised by a distinct pattern of labral pathology, with anteriorly localised labral damage, that does not extend to the anterosuperior portion of the acetabulum...

INTRODUCTION: Cobalt toxicity in patients with hip arthroplasty is a rare complication, but it should be considered in those patients who, after a ceramic fracture, were implanted with a metal-on-polyethylene prosthesis. The complete removal of ceramic particles during revision surgery can be complicated. If the bearing surface is replaced with a metal-on-polyethylene prosthesis, these residual ceramic particles may wear down the chrome-cobalt head, producing localised metallosis. This can trigger blood metal ion levels to rise, causing systemic toxicity...

BACKGROUND: Total hip arthroplasty (THA) offers an effective method of pain relief and restoration of function for patients with end-stage arthritis. The anterior approach (AA) claims to benefit patients with decreased pain, increased mobilisation and decreasing length of hospital stay (LOS). In a socialised healthcare platform we questioned whether the AA, compared to posterior (PA) and lateral (LA) approaches, can decrease the cost burden. METHODS: Using a retrospective matched cohort study, we matched 69 AA patients to 69 LA and 69 PA patients for age ( p = 0...

BACKGROUND: Offset and leg length (LL) restoration are critical for the achievement of a stable, well-functioning hip following total hip arthroplasty (THA). Several techniques are described in the literature, including a hip calibration gauge. We question whether meticulous preoperative planning of a specific surgical technique in combination with the utilisation of a calibration gauge can provide an accurate offset and LL restoration. METHODS: Retrospective review of 101 unilateral THAs via a posterior approach by a single surgeon...

INTRODUCTION: Foot drop is a potentially debilitating complication following injury to the sciatic nerve during primary total hip arthroplasty (THA). The aim of this study was to determine the incidence, risk factors and outcome of this complication within one large surgical practice. METHODS: We analysed the records of 10,624 primary THAs carried out between January 1993 and November 2017 using a posterior approach. All were under the care of the senior author...

BACKGROUND: Polycarbonate urethane (PCU) is a bearing surface with a lower modulus of elasticity than polyethylene or ceramic and is thought to more closely replicate the tribology of native hyaline cartilage. The purpose of this study was to determine the clinical outcomes with the use of PCU in elective total hip arthroplasty (THA). METHODS: We carried out a prospective observational study in which 157 patients underwent elective THA with a metal-on-PCU hip system...

BACKGROUND: Hip fractures in the elderly are associated with advanced comorbidities and high mortality rates. Mortality prediction models can support clinicians in tailoring treatment for medical decision making in frail elderly patients. The aim of this study was to develop and internally validate the Brabant Hip Fracture Score, for 30-day (BHFS-30) and 1-year mortality (BHFS-365) after hip fracture. MATERIAL AND METHODS: A cohort study was conducted in 2 hospitals on operatively treated patients of 65 years and older with a hip fracture...

PURPOSE: To determine if initial treatment affects the outcome of total hip arthroplasty (THA) after acetabular fracture. METHODS: 49 patients (49 hips) initially treated non-operatively followed some months later by THA in conjunction with acetabular reconstruction (Group 1) and 29 patients (29 hips) who had undergone THA after a previous osteosynthesis (Group 2) were assessed. The mean follow-up was 11.7 (range 5-23) years. RESULTS: 3 acetabular components were revised for aseptic loosening in Group 1 and 2 in Group 2...

BACKGROUND: Studies have shown high-volume surgeons and hospitals deliver higher value care. The aims of this study were to establish meaningful thresholds defining high-volume surgeons and hospitals performing hip fracture surgery and to examine the relative market share of hip fracture cases using these surgeon and hospital strata. METHODS: We performed a retrospective cohort study in a database of 103,935 patients undergoing hip fracture repair. We generated stratum-specific likelihood ratio (SSLR) models of a receiver operating characteristic (ROC) curve using length of stay (LOS) and cost value metrics...

INTRODUCTION: Patient-reported outcome measures (PROMs) are used increasingly, but for young patients with hip complaints, traditional scoring systems have a ceiling effect that limits their usability. We developed and validated the Super Simple Hip (SUSHI) score, a PROM specifically targeted at younger patients with hip complaints. Although the SUSHI measured hip problems adequately, the responsiveness of its activity rating component was considered inadequate. Consequently, we replaced the activity rating component by the University of California, Los Angeles (UCLA) activity scale...
