Central acetabular fracture dislocation is usually caused by high-energy external trauma. However, 26 cases that occurred as a result of a seizure attack appeared in the literature from 1970 to 2007, with the seizure attacks themselves caused by many different factors. In this setting, the central acetabular fracture not caused by direct trauma might initially remain unnoticed leading to a delayed diagnosis. In some cases, this may lead to death as a result of massive blood loss. We here present a case of bilateral central acetabular fracture dislocation as a result of a seizure attack.
Intra-articular osteoid osteoma is uncommon accounting for approximately 12% of all osteoid osteomas. It presents diagnostic and therapeutic challenges since several traumatic or degenerative pathologies of the joint can be simulated with delay in the diagnosis. We report the clinical, radiographic, and histopathological findings in 2 cases of intra-articular osteoid osteoma of the femoral neck and of the acetabulum. Technical aspects of arthroscopic excision and results of surgery are discussed. Arthroscopy allowed complete excision of the osteoid osteomas, with a short postoperative rehabilitation and excellent functional results.
Meralgia paresthetica is an entrapment neuropathy involving the lateral femoral cutaneous nerve of the thigh. Patients complain of a persistent burning sensation, tingling and aching pain, and hypersensitivity or hyposensitivity in the anterolateral aspect of the thigh. Numerous direct and indirect causes for the disease have been suggested in the literature. We present 12 cases that were diagnosed to have meralgia paresthetica due to tight new fashion low cut trousers ('taille basse'). The diagnosis was confirmed by injecting a small amount of a short acting local anesthetic around the lateral femoral cutaneous nerve which alleviated the symptoms for several hours. Electrophysiologic studies were sensitive in 83.3% of the cases. All cases were treated successfully using conservative methods, namely avoiding tight trousers, local steroid infiltration and weight reduction.
The purpose of this study is to report a rare case of acetabular osteochondroma with a unique clinical presentation occurring in an adult with normally developed hips. The distinctive size and location of the lesion required an open approach with surgical dislocation of the hip for complete resection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
