Pathogenesis And Radiological Findings In Rare Case Of Salter Harris Type I Distal Tibial Fracture With Associated Osteonecrosis In The Paediatric Population.

Salter-Harris type I fractures of the distal tibia are commonly seen in paediatrics and management of such fractures follows an algorithm established in the literature. Despite this, osteonecrosis of the distal tibia can subsequently develop. Osteonecrosis or avascular necrosis is cell death that occurs secondary to trauma, metabolic disturbances, sickle cell disease, or medication side effect. It most frequently affects the femur, talus, or humerus, and rarely the tibia. Radiographs and MRI are pivotal in making a timely diagnosis in order to minimize patient discomfort. To the best of our knowledge, there has only been one previous documented case of osteonecrosis following a Salter Harris Type I distal tibial fracture. Here, we present the second such case.

Post-traumatic osteochondroma of the distal femur.

Osteochondroma are the most common benign primary bone tumor. They are bony outgrowths surrounded by a characteristic cartilaginous cap, most commonly arising from the long bones. They are most often asymptomatic, usually discovered as incidental findings before the third or fourth decade of life. Although the exact pathogenesis is not fully established, there have been reports of these tumors arising after incidents such as fractures, trauma, radiation, and stem cell transplants. There have been only a few cases describing the development of osteochondroma after traumatic events. This report presents a documented case of an osteochondroma arising at the site of a previous femoral fracture, 10 years after the initial trauma.

A rare case of cubonavicular coalition.

Tarsal coalition is a condition described by partial union between tarsal bones. Its clinical significance is the potential cause for chronic pain in the ankle and foot. Diagnosis of this condition may be delayed until adolescence or early adulthood, and is often made incidentally on examination for other purposes. Treatments for this condition can range from conservative options to surgical approach. The calcaneonavicular and talocalcaneal subtypes make up the majority of this condition, with involvement among other tarsal bones much rarer in comparison. This report illustrates the cubonavicular subtype, which has only been described in very small number cases.

The debate is still open; benign or malignant: a case report of a multifocal epithelioid haemangioma of fibula.

In this case, we report an epithelioid haemangioma (EH) of the fibula with ill-defined multifocal lesions and a resultant pathologic fracture. Based on radiographic appearance, these lesions were initially thought to represent a malignant process, such as primary malignant bone tumour, metastases or multiple myeloma. Osseous EHs are rare. Although they can present as multifocal lesions, the majority of bony EHs are solitary and arise in the diaphysis or metaphysis of long tubular bones, with a predilection for the lower extremity. Non-specific radiological findings, debatable cytological appearance and unpredictable clinical growth patterns commonly cause misdiagnosis of malignancy. To the best of our knowledge, a case of EH with multiple growing lesions of the fibula has not yet been reported in the literature.
