Subtrochanteric rotational osteotomy for young adults with hip pain due to femoral maltorsion.
CONCLUSIONS: Subtrochanteric rotational osteotomy with hip arthroscopy improves the hip subjectively without leading to objective patellofemoral instability nor changes in the patellofemoral geometry compared to contralateral side. The technique of subtrochanteric rotational osteotomy is safe and reliable. PMID: 32750252 [PubMed - as supplied by publisher] (Source: Hip International)

Can the use of an inclinometer improve acetabular cup inclination in total hip arthroplasty? A review of the literature.
DISCUSSION: This review demonstrates that using an inclinometer improved the surgeon's ability to achieve their intended inclination (both operative and radiographic) and reduced the incidence of positioning outside the safe-zone. However, only 2 of the studies were randomised control trials and these resulted in opposing conclusions. Therefore, further studies looking at the use of inclinometers would prove useful in understanding their true benefit. PMID: 32750263 [PubMed - as supplied by publisher] (Source: Hip International)

Insulin-dependent diabetes mellitus is an independent risk factor for postoperative complications in aseptic revision total hip arthroplasty.
Abstract INTRODUCTION: Revision total hip arthroplasty (rTHA) is becoming a more common procedure due to the increasing volume of primary total hip arthroplasty. Diabetes mellitus (DM) is currently projected to affect 4.4% of the global population by 2030. Diabetes has been associated with poor outcomes for a variety of surgical interventions. However, the impact of insulin dependence has yet to be fully understood. The aim of this study was to determine the impact of insulin dependence on acute postoperative complications following rTHA. METHODS: A retrospective cohort study was conducted using the American ...

Early failure of an uncemented femoral stem, as compared to two other stems with similar design, following primary total hip arthroplasty performed with direct anterior approach.
CONCLUSIONS: In this specific cohort of patients, the increased rate of femoral stem aseptic loosening was implant-related and was attributed only to a specific type of femoral stem (Quadra-S). No relation to other factors was proven suggesting that the surface characteristics of this femoral stem and the lack of bioactive coating are responsible for the observed early femoral failures. These findings should be confirmed by additional registry work and larger population sample sizes are needed to evaluate the prosthesis performance after implantation through the DAA.

Resuming hip and knee arthroplasty after COVID-19: ethical implications for well-being, safety and the economy.
Abstract Reinstating elective hip and knee arthroplasty services presents significant challenges. We need to be honest about the scale of the obstacles ahead and realise that the health challenges and economic consequences of the COVID-19 pandemic are potentially devastating. We must also prepare to make difficult ethical decisions about restarting elective hip and knee arthroplasty. These decisions should be based on the existing evidence-base, reliable data, the recommendations of experts, and regional circumstances.

The fate of positive intraoperative cultures following conversion total hip arthroplasty.
CONCLUSIONS: Patients undergoing conversion THA from prior hip or acetabular fracture have a high rate of positive intraoperative cultures. As such, all patients undergoing conversion THA from prior hip or acetabular fracture fixation should undergo thorough diagnostic workup prior to surgery, and have intraoperative cultures obtained during surgery if infection remains suspicious. Further work should be performed to develop MSIS criteria for preoperative management of patients undergoing conversion THA.

Multiple deep tissue cultures in primary total hip arthroplasty: prognostic value for periprosthetic infection.
Abstract BACKGROUND: The risk of infection after total hip replacement (THR) is significant, with negative impact on quality of life and high costs. Bacteria can contaminate the surgical site despite aseptic techniques; however, there is debate regarding the benefit of identifying bacteria during the primary procedure. Although taking multiple samples for culture is a well-established practice in revision arthroplasty, doing so in primary cases remains controversial. We aimed to investigate whether there is a prognostic value in the culture of samples taken during primary THR, seeking a correlation between the pos...

Hip abductor tendon tears: where are we now?
Abstract Hip abductor tendon tear is a difficult problem to manage. The hip abductor mechanism is made up of the gluteus medius and minimus muscles, both of which contribute to stabilising the pelvis through the gait cycle. Tears of these tendons are likely due to iatrogenic injury during arthroplasty and chronic degenerative tendinopathy. Ultrasound and magnetic resonance imaging have provided limited clues regarding the pattern of disease and further work is required to clarify both the macro and microscopic pattern of disease. While surgery has been attempted over the last 2 decades, the outcomes are variable a...

Abstract Prosthetic joint infection (PJI) is 1 of the most challenging potential complications following total joint arthroplasty. Several surgical treatment strategies have been proposed for management of this diagnosis. The single-stage approach has been gaining popularity in contemporary literature. 1 fundamental aspect in the management of hip PJI is the administration of antibiotics, usually intravenously immediately after surgery, followed by a period of oral antibiotics. The optimal duration of the period of antibiotic therapy is undecided. The aim of this paper is to examine the trend in intravenous antibi...

High rates of implant fracture of a generic polished tapered femoral stem.
CONCLUSIONS: An alarmingly high rate of early implant fractures was seen using this specific type of cemented stem, particularly when using smaller implant sizes in obese patients. Although based on a proven design, a specific modification led to a stress riser in the neck area, which resulted in a high incidence of implant failure. This series underlines the importance of a stepwise introduction into the market of new orthopaedic devices even when based on established concepts. Generic stems may not behave as the original stem upon which it was designed. PMID: 32459520 [PubMed - as supplied by publisher] (Source: Hip International)

Course of the sciatic nerve on magnetic resonance imaging in patients with osteoarthritis of the hip.
Abstract BACKGROUND: Sciatic nerve palsy is a serious complication after total hip arthroplasty (THA). This is the first study to report the relationship between the sciatic nerve and the acetabulum on magnetic resonance imaging (MRI) before THA. METHODS: 235 patients underwent 261 elective, primary THAs via the mini-incision posterolateral approach. We measured the horizontal distance (mm) and vertical distance (mm) from the posterior edge of the acetabulum to the sciatic nerve by T1-weighted imaging on an axial section of the centre of the femoral head. We defined the Dysplastic Group as having a posterior ...

Surgical management of chronic pelvic instability following periacetabular osteotomy nonunion.
CONCLUSIONS: To our knowledge, this is the largest case series of surgically managed PAO nonunion. Pelvic instability resulting from nonunion and stress fracture can be satisfactorily addressed by mobilising, grafting and plating the nonunion at the superior pubic ramus. The modified Stoppa approach is suitable in most cases, allowing excellent exposure whilst minimising the insult to soft tissues. The altered anatomy of the pelvis following PAO should be anticipated to reduce the risk to nearby neurovascular structures.

Characterising acetabular component orientation with pelvic motion during total hip arthroplasty.
CONCLUSIONS: Intraoperative pelvic motion can significantly affect final cup position, and this should be accounted for when placing acetabular components during total hip arthroplasty. Based on this study, intraoperative adjustment of the acetabular component position based on pelvis motion may be implemented to improve postoperative component position.

Incidence and risk factors for perioperative death after revision total hip arthroplasty: a 20-year analysis.
We describe patterns in incidence and risk factors for perioperative death after revision THA. METHODS: Using the National Hospital Discharge Survey, we identified nearly 700,000 cases of revision THA from 1990 through 2010. Procedure incidence, perioperative mortality rates, comorbidities, discharge disposition, and duration of hospital stay were analysed. Multivariable logistic regression was used to identify independent risk factors for perioperative death. Alpha = 0.01. RESULTS: Population-adjusted incidence of revision THA per 100,000 people increased from 9.2 cases in 1990 to 15 cases in 2010 (p
