Septic arthritis caused by Mycobacterium marinum.

The incidence of infection by Mycobacterium marinum is rising, mainly due to the increasing popularity of home aquariums. The infection typically manifests as skin lesions, with septic arthritis being a rare presentation form. The disease is difficult to diagnose even when there is a high clinical suspicion, as culture in specific media may not yield positive findings.

Reduction in neural injury with earlier delivery in a mouse model of congenital myelomeningocele: laboratory investigation.

Object: The authors undertook this study to assess the effect of preterm delivery with respect to neural protection in a congenital myelomeningocele (MMC) mouse model.

Methods: After confirmation of pregnancy in 15 female mice, a congenital MMC model was produced by administration of retinoic acid on the 7th day of gestation. The pregnant mice underwent cesarean sections on Days 15 (n = 5, Group E15), 17 (n = 5, Group E17), and 19 (n = 5, Group E19).

Simultaneous development of Dieterich disease and Freiberg disease.

Dieterich disease is an uncommon arthropathy of the hand, with few studies published. This lesion shares a similar etiopathogenesis with Freiberg disease, although the association of both conditions has only been described once. We report a 65-year-old man consulting for inflammatory pain in his right hand of 1 month's duration and also in his right foot of 4 months' duration.

Massive psoas haematoma causing lumbar plexus palsy: a case report.

An 84-year-old man who was receiving oral anticoagulation therapy presented with complete lumbar plexus palsy caused by a massive psoas haematoma. Conservative treatment rather than drainage of the haematoma was undertaken, because of the risk of bleeding complications and mortality. At the one-year follow-up, the patient had no clinical signs of neurological recovery.

Fracture of the anteromedial tibial plateau associated with posterolateral complex injury: case study and literature review.

We report an unusual case of anteromedial tibial plateau compression fracture following hyperextension and forced varus of the knee, resulting in an anterior bone fragment large enough to require osteosynthesis. This uncommon lesion was associated with posterolateral complex injury, diagnosed with magnetic resonance imaging (MRI), while both cruciate ligaments were preserved. After proceeding with tibial plateau osteosynthesis, a peroneal tendon allograft was used for supplementation repair of the lateral collateral ligament and biceps tendon in a single surgical intervention.

Lateral subtalar dislocation associated with bimalleolar fracture: case report and literature review.

Subtalar dislocation is an uncommon injury that affects the talocalcaneal and talonavicular joints, with the tibiotalar and calcaneocuboid joints remaining intact. The 4 types of subtalar dislocation are medial, lateral, anterior, and posterior, although the latter 2 are rare. These injuries-especially lateral dislocation-occur as a result of high-energy trauma.

Multicentric liposarcoma.

Liposarcoma is one of the most common malignant soft tissue tumours. It usually presents as a single mass, and the prognosis varies according to the degree of histological differentiation. Multicentric liposarcoma is an unusual presentation of this tumour in which several independent lesions develop and generally display an aggressive pattern.

Recurrent adjacent segment disease and cauda equina syndrome.

Purpose: A case of cauda equina lesion as a result of recurrent adjacent segment degeneration (ASD) after multiple lumbar fusions is reported. ASD might be a consequence of biomechanical overload or simply a normal degenerative process. The reported clinical relevance of ASD is rather low.

Proximal tibiofibular dislocation associated with fracture of the tibia: a case report.

Introduction: We report a case of proximal tibiofibular dislocation associated with an ipsilateral tibial fracture, a rare association of injuries that can remain undiagnosed.

Case Presentation: A white 23-year-old man experienced a road accident and was diagnosed with proximal tibiofibular dislocation associated with an open fracture of the tibia and injury to the external popliteus sciatic nerve. He was treated immediately with an intramedullary tibial nail and a cancellous screw at the level of the proximal tibiofibular articulation.

Avascular necrosis of the metacarpal head: Dieterich's disease.

A 68-year-old woman presented with an osteolytic image on the metacarpal head of the ring finger, first attributed to inflammatory or septic arthritis. She had experienced increasing pain three months before presentation, requiring orthopaedic treatment. At the time of clinical assessment, there was some limitation in the range of movement, accompanied by local pain and chronic swelling.
