Pinckney Fracture: do Not Underestimate Trauma of the Distal Phalanx of the Hallux

Toe injuries are common in the emergency department and most of them are treated conservatively. In some circumstances, these injuries can present as a physeal fracture with concomitant soft-tissue injury affecting the nail bed and resulting in a hidden open fracture. To adequately treat these patients, a high index of suspicion is needed to diagnose and treat the open fractures and to prevent complications suc...

Peri-Prosthetic Bone Cysts After Total Ankle Replacement. A Systematic Review a...

Background: Periprosthetic cystic osteolysis is a well-known complication of total ankle replacement. Several theories have been proposed for its aetiology, based on individual biomechanical, radiological, histopathology and outcome studies. Methods: Studies that met predefined inclusion/exclusion criteria were analysed to identify literature describing the presence of peri-prosthetic ankle cystic osteolysis. Q...

Sacroileítis Piógena: Lecciones Aprendidas de una Serie de Casos Atípicos

Pyogenic sacroiliitis (PSI) is a rare condition that amounts to 1% to 2% of all joint infections in the paediatric age group. Its diagnosis is often difficult and delayed due to its nonspecific signs, symptoms and physical findings. Also, the identification of the causative microorganism is frequently challenging due to a high proportion of negative blood cultures and the risks involved in joint aspiration in t...

Carpal Synovitis with Capitate Bone Tuberculosis in a Child

We present a 10-year-old boy with 2-month duration non-traumatic wrist pain and inflammatory signs. Due to elevated inflammatory markers on blood tests, with an increase in radiocarpal and intercarpal joints synovial fluid and no bony lesions, the patient was submitted to wrist arthrocentesis for the suspicion of septic arthritis. The patient did not improve on conventional treatment, however. An MRI showed syn...

Aloenxerto de Tendão de Aquiles no Tratamento de Rotura Crónica do Tendão Rotul...

A disrupção do aparelho extensor, nomeadamente a rotura do tendão rotuliano, é uma complicação grave após artroplastia total do joelho. A sua reconstrução em roturas crónicas é tecnicamente exigente e, dada a sua raridade, carece de um gold standard estabelecido para o seu tratamento. Este artigo relata a técnica e resultados obtidos com a utilização de um aloenxerto de tendão de Aquiles, na reparação de uma ro...

Rigidez Pós-Artroplastia Total do Joelho

A artroplastia total do joelho tem por objectivos minimizar a dor, promover a estabilidade articular durante a marcha e maximizar a amplitude de movimento. A prevalência de rigidez pós-artroplastia total do joelho pode atingir os 25%. A comunidade científica aponta, como principais factores de risco para o seu surgimento, uma menor amplitude articular pré-operatória, a pouca colaboração do doente num programa d...

Artroplastia Unicompartimental do Joelho Oxford Phase 3. Resultados a Médio Prazo

Introdução: A artroplastia unicompartimental evoluiu nos últimos 40 anos, sendo hoje em dia considerada uma estratégia cirúrgica apropriada para a osteoartrose do compartimento interno da articulação do joelho. Desenvolvimentos nos instrumentos cirúrgicos, desenho do implante, abordagem cirúrgica e selecção dos doentes levaram a uma grande melhoria dos resultados pós-operatórios e aumento da longevidade das pró...
