Patellar (knee cap) dislocation occurs when the patella disengages completely from the trochlear (femoral) groove. It affects up to 42/100,000 people, and is most prevalent in those aged 20 to 30 years old. It is uncertain whether surgical or non-surgical treatment is the best approach. This is […]

A high-tech way to learn about the body Virtual reality may soon do away with the need for human cadavers to train medical students in anatomy. Case Western Reserve University’s School of Medicine was the first college to remove human corpses from the anatomy curriculum. Instead, the school […]

Hip Dislocation a serious problem.

In a former Boeing manufacturing facility near Seattle’s waterfront, a six-year old startup is readying a system it says will change surgery. Proprio‘s technology enables surgeons to see key structures on a screen in three dimensions in real time. The system helps clinicians place incisions and […]

Hip-spine syndrome is a complex challenge for orthopedic surgeons. We present a 60-year-old female with a history of spinal fusion and total hip arthroplasty. The patient underwent extension of the previous fusion with sacropelvic fixation, and 5 months later she presented with left posterior […]

We present the case of a man in his 60s with a transtibial amputation (TTA) undergoing total knee replacement (TKR) for symptomatic osteoarthritis (OA). It is unusual to develop OA in the ipsilateral knee to TTA; and while it is postulated that this is because patients preferentially load their […]

Older knee replacement designs are just as effective as newer models—according to new research from the Norfolk and Norwich University Hospital and University of East Anglia.

One of the most frequent concerns of the increasing number of patients undergoing shoulder arthroplasty is the possibility to resume sport after surgery. This systematic review determined the rate of return to sport after total shoulder arthroplasty (TSA) and hemiarthroplasty (HA)./r/nThe PRISMA […]

The most common cause for catching or snapping in the finger is stenosing tenosynovitis, that is, trigger finger. Although less common, snapping can also occur as a result of extensor mechanism injury. Among these injuries, sagittal band rupture is most common and leads to snapping at the […]

We report the case of a 35-year-old patient who presented with a septic residual synovial cavity infection 8 weeks after a through-the-knee amputation because of a parosteal sarcoma. An endoscopic evacuation of the turbid fluid and synovial debridement through parapatellar portals as in a standard […]

Ehlers-Danlos syndrome (EDS) causes joint hypermobility and joint dislocation. Since there are no reports of proximal tibiofibular joint (PTFJ) dislocation caused by EDS, little is known about the long-term course of this disease. A woman in her 40s presented with a posterolaterally depressed […]

This study investigated the impact of the Covid-19 pandemic in Europe on consultations, surgeries, and traumas in the field of orthopaedic and trauma surgery. Strategies to resume the clinical activities were also discussed./r/nThis systematic review was conducted according to the Preferred […]

Rates of reverse total shoulder arthroplasty (rTSA) continue to grow. Glenoid bone loss and deformity remains a technical challenge to the surgeon and may reduce improvements in patients' outcomes. However, there is no consensus as to the optimal surgical technique to best reconstruct these […]

Liner dissociation (LD) is a rare catastrophic mechanical failure of total hip arthroplasty (THA). The study aims at reviewing the available literature regarding liner dissociations to point out their prevalence, describing any possible association and highlighting the surgical management at the […]

The aim of this study was to describe our experience with ultrasound-guided supraclavicular brachial plexus blocks performed by pediatric emergency physicians for the purpose of forearm fracture reductions in the emergency department./r/nWe present a case series of 15 pediatric patients aged 7 to […]

A substantial number of randomized controlled trial (RCT) studies in total joint arthroplasty (TJA) are published each year in the United States (US). However, it is unknown how closely the demographic and clinical characteristics of these cohorts resemble that of the US patient population […]

Posttraumatic mental health issues following traumatic limb amputations in children have been commonly reported worldwide. Traumatic limb amputationsarecatastrophic injuries/events and often have various long term psycho-social impacts on children. We report a case of 8 year-oldfemale child […]

Spontaneous rupture of the extensor pollicis longus (EPL) tendon at the wrist has been reported with predisposing factors to include distal radius fractures, rheumatoid arthritis, systemic or local steroids, and repetitive abnormal motion of the wrist joint.We present a case of an 18-year-old […]

Below-knee amputation is the treatment of choice for distal tibia malignancies, considering the specific anatomic features of the distal leg and ankle. However, advances in imaging modalities and adjuvant therapies and improved surgical techniques have made limb salvage surgery increasingly […]

Participate and win the chance to have your clinical case featured on the AO website, myAO blog and on the Clinical Case Roundup that will be sent in January to the myAO users with interests related […]

While ultrasound has become a preferred tool for musculoskeletal imaging, differing ultrasound findings that have been reported in patients with adhesive capsulitis can create confusion and misconceptions. This systematic review was aimed at summarizing all the ultrasound features currently […]

No consensus exists on rehabilitation programmes after medial patellofemoral ligament reconstruction (MPFLR) with or without tibial tuberosity osteotomy (TTO).
