Catastrophic wear in uncemented acetabular cups after Total Hip Arthroplasty. A case series.

Introduction: Catastrophic wear is a rare outcome following Total Hip Arthroplasty (THA), documented to happen in less than 0.5% of THA. We present 5 cases of revision THA performed successfully on 5 patients presenting Catastrophic wear, following Total Hip Arthroplasty (THA).

Fracture of the astragalus in pediatric patients, an unusual entity.

Introduction And Importance: The fracture of the astragalus is an unusual bone fracture (Ladero and Concejero, 2004) and is even more unusual in pediatric patients. The astragalus is a bone surrounded by cartilage and other structures making it difficult to appreciate on an X-ray which can lead to misdiagnosis (Ladero and Concejero, 2004; Inal and Inal, 2014) and could lead to not applying the right treatment and risk avascular necrosis or other sequelae.

Case Presentation: 3-year-old male with foot pain and edema+++, unable to walk or stand up since a fall 2 days before, had a doubtful diagnosis after an x-ray showed no apparent bone injury.

Solitary enchondroma in a metatarsal bone, an incidental discovery.

Introduction: Enchondromas are rare benign bone tumours and their discovery is usually incidental, since in most cases it presents with no symptoms.

Presentation Of Case: A 30 year old male who comes to the office after suffering a forced inversion of the left foot, he has edema of the left lateral malleolus, pain and is unable to walk; no deformities or other alterations are observed and palpable pulses of adequate intensity and frequency are recorded. The radiography shows soft tissue edema and no bone lesions.

Bilateral femoral neck stress fractures in a high-performance young female runner.

A 16-year-old female patient showed up at the orthopaedics unit complaining of intolerable pain on her left hip. While being questioned and her clinical history written down, she shared that as part of her daily exercise routine, she ran 10 miles (16 km) daily at a speed of 9.5-10.

Muscular tendinous junction rupture of the posterior tibial tendon after closed bimalleolar ankle fracture.

In this case report, we present an acute rupture in the muscular tendinous junction of a posterior tibialis muscle in a bimalleolar closed ankle fracture after a high-energy trauma in a 30-year-old patient with no significant medical history. Fracture was confirmed by simple X-rays, and was treated with an open reduction in which both of the fractures were treated with osteosynthesis material and reparation of the syndesmosis. If left untreated, this uncommon finding can result in a bad postsurgical outcome; we believe this injury is more common but under-reported in the literature.

Dominique-Jean Larrey: the effects of therapeutic hypothermia and the first ambulance.

The fields of emergency medicine and resuscitation are indebted to the Baron Dominique-Jean Larrey (1766-1842) for significant advances in patient care. Larrey was a great surgeon who served in the French army during Napoleon's rule. He developed one of the first ambulance services, utilized positive pressure ventilation, and introduced hypothermia as a form of therapy.
