dGEMRIC (delayed gadolinium-enhanced MRI for cartilage) and T2-mapping are evolving techniques to evaluate cartilage defects and repair. #tusharmehta #OrthopaedicsPlus
#MedEd Adamantinoma is a rare malignant bone tumor with a propensity for late metastasis. It has a high incidence of local recurrence unless resected with a wide margin. Chemotherapy and radiation therapy are not helpful in the treatment of this disease. Amputation generally is not necessary because a diaphyseal resection is usually possible
Ossification Centres of Carpal Bones : Capitate: 1-3 months Hamate: 2-4 months Triquetrum: 2-3 years Lunate: 2-4 years Scaphoid: 4-6 years Trapezium: 4-6 years Trapezoid: 4-6 years Pisiform: 8-12 years Capitate is the first one and Pisiform is the last one to ossify. Ball & Socket Joints : (Mnemonic –> THIS) T –> TaloCalcaneoNavicular Joint […]
Avulsion fracture of the medial distal femur at the origin of the medial collateral ligament is known as a Stieda fracture and may later develop into a Pelligrini-Stieda lesion.
Classification Type I: Anteriorly angulated fracture of the ulna associated with an anterior dislocation of the radial head Type II: Posteriorly angulated fracture of the ulnar diaphysis associated with a posterior dislocation of the radial head Type III: Fracture of the ulnar metaphysis associated with a lateral or anterolateral dislocation of the radial head Type […]
Interdigital Neuroma –> The only proven risk factor for development of an interdigital neuroma is female gender, which likely is related to the use of fashionable shoes that force plantar flexion of the metatarsal heads and secondary hyperdorsiflexion of the metatarsophalangeal joints.
The alpha angle is a measurement used in the ultrasonographic assessment of developmental dysplasia of the hip (DDH). The angle is formed by the acetabular roof to the vertical cortex of the ilium and thus reflects the depth of the bony acetabular roof. This is a similar measurement to the acetabular angle. The normal value […]
The radiographs show localized diffuse cortical thickening that is characteristic of melorheostosis. The condition may be monostotic or it may involve many bones in one extremity (monomelic) in the distribution of a sclerotome. Bone scans will show increased uptake at the site or sites of skeletal involvement. Long tubular bones are most commonly involved. Melorheostosis […]
Intercondylar eminence fractures in skeletally immature patients usually result from injuries that would cause ACL tears in skeletally mature patients. Meyers and McKeever reported that a large number of bicycle falls produce this type of injury in children. However, intercondylar eminence fractures can be caused by a spectrum of sporting activities and by motor vehicle […]
