[When should a gluteus medius tendon rupture be operated on ?].

The gluteus medius allows hip abduction and stabilization of the pelvis when walking. A rupture of the gluteus medius tendon is associated with lateral hip pain, weakness, a positive Trendelenburg sign, and a limp. Diagnosis is confirmed by ultrasound or MRI.

Reliability of the Harris Hip limping sub-score in patients undergoing total hip arthroplasty.

Purpose: In patients undergoing total hip arthroplasty, limping is a significant symptom, often assessed with the limping sub-score of the Harris Hip Score. However, the reliability of this sub-score has not been specifically investigated. The purpose of this study is to investigate the intra- and inter-rater reliability of this sub-score.

[What surgical treatment for femoro-acetabular impingement?].

Femoroacetabular impingement (FAI) is a frequent cause of hip pain in young people and athletes. It requires a complete work-up, including X-rays, hip arthro-MRI and CT coxometry with measurement of femoral torsion. The surgical management of CFA must be adapted to the morphological anomalies of the femur (cam), acetabulum (pincer) and femoral torsional disorders.

[Customized 3D cutting guides : what applications in orthopedic surgery ?].

3D printing is a technology that has been evolving rapidly over the past twenty years. It is an additive manufacturing process which allows the creation of objects without geometry restrictions. This process has applications in orthopaedic surgery through personalized cutting guides and implants which offer the possibility to treat complex pathologies such as tumoral surgery, architectural defects of the acetabulum and malunions.

Extensive skin necrosis following total hip arthroplasty performed through the direct anterior approach.

Background: Total hip arthroplasty is a widely performed surgical procedure, which enables patients to regain mobility, alleviates pain, and improves overall quality of life. Periarticular multimodal drug infiltration (PAI) is increasingly being used as an effective postoperative pain management, decreasing the systemic consumption of opioids. Extensive postoperative skin necrosis without a deep joint infection as a complication of total hip arthroplasty with PAI has not yet been described.

[Dislocation after total hip arthroplasty : how to avoid it ?].

Dislocation after hip replacement is a complication that can have dramatic consequences for the patient. The purpose of this article is to review the different parameters influencing stability and how to reduce this risk. The approach, the diameter of the femoral head, and the use of dual-mobility acetabular cups have led to a drastic reduction in the rate of dislocation, particularly in patients at risk, in cases of imbalance of the spino-pelvic complex, or in cases of revision surgery.

Subjective knee apprehension is not associated to physical parameters 6-12 months after anterior cruciate ligament reconstruction.

Purpose: Anterior cruciate ligament (ACL) rupture is a common injury and psychological parameters measured at 6-8 months are said to be almost more predictive for return to sport (RTS) than physiological. Purpose was 1) to evaluate the correlation between knee apprehension using ACL-RSI and physical factors after ACL reconstruction (ACLR), 2) to assess the correlation between ACL-RSI and patient parameters (age, pivot-sport, BMI), and 3) to evaluate ACL-RSI over time.

Methods: Patients with ACLR with or without meniscal repair between 2013 and 2020 were retrospectively analyzed.

Ulna hook plate osteosynthesis for ulna head fracture associated with distal radius fracture.

Background: Distal ulna head or neck fracture is commonly associated with distal radius fracture. Treatment of these fractures remains controversial. Plate osteosynthesis is commonly performed.

Acetabular Peri-Prosthetic Fractures-A Narrative Review.

Acetabular peri-prosthetic fractures are rare but their incidence is rising due to the increased prevalence of total hip arthroplasty, the increasing life expectancy and the growing functional demand of an ageing population, the incidence of primary total hip arthroplasty is increasing. They are either intra-operative or post-operative and have various aetiologies. Several factors such as implant stability, bone loss, remaining bone stock, fracture pattern, timing, age and co-morbidities of the patients must be considered for adequate treatment.

All-suture technique for fixation of unstable displaced distal clavicle fracture.

Background: Displaced Neer type II and V clavicle fractures are usually treated surgically in active patients. However, distal fragment fixation remains a challenge, and no consensus has been established regarding the optimal surgical treatment. Osteosuture techniques have been popularized over the last decade, and multiple different techniques have been described.

[Should allografts become gold-standard in ligamentous knee surgery ?].

Allografts in reconstructive knee surgery are an interesting option, due to the absence of donor site morbidity, its rather easy intraoperative handling, the different sizes, shorter surgical time, and therefore less peroperative risks. The risk of infection is very low. Their results are similar when non-irradiated and non-sterilized allografts are used in terms of postoperative strength, return to sport, and comparable stability testing.

Two weeks versus four weeks of antibiotic therapy after surgical drainage for native joint bacterial arthritis: a prospective, randomised, non-inferiority trial.

Objective: The optimal duration of postsurgical antibiotic therapy for adult native joint bacterial arthritis remains unknown.

Methods: We conducted a prospective, unblinded, randomised, non-inferiority study comparing either 2 or 4 weeks of antibiotic therapy after surgical drainage of native joint bacterial arthritis in adults. Excluded were implant-related infections, episodes without surgical lavage and episodes with a follow-up of less than 2 months.

[Total Hip arthroplasty in patients younger than 50 years].

Total hip replacement can provide pain relief and restore function in patients suffering from hip arthritis, including in those under the age of 50. However, shortened implant longevity in this age group has been a concern because the clinical results after revision surgery are inferior to those after primary hip arthroplasty. Technical choices (approach, implants, type of fixation and bearing couple) must be made to maximise longevity based on published data and thoroughly discussed with the patient.
