Proximal femoral Osteotomy

Proximal femoral osteotomy is a joint-sparing procedure that relies on maintaining the biologic integrity of the femoral head. Once common for hip dysplasia and arthritis of the hip, proximal femoral osteotomies are performed less commonly now. But they are still used in the treatment of hip fracture nonunions and malunions and in cases of congenital […]

Risser Sign and Its Use in Scoliosis

The Risser sign, also called Risser index or Risser classification is a system used to assess and grade skeletal maturity based on the level of ossification and fusion of the iliac crest apophyses. The apophyses (singular: apophysis) are the normal bony outgrowths which have separate ossification centers and eventually fuse with the bone in time. Iliac […]

Ollier Disease – Causes, Presentation and Treatment

Ollier’s disease is a rare, nonhereditary skeletal disorder characterized by a multifocal intramedullary proliferation of hypercellular dysplastic cartilage. It is a type of enchondromatosis. Maffucci’s syndrome is another type of enchondromatosis where the skeletal lesions are accompanied by hemangiomas of skin, soft tissu, and viscera. Enchondromatosis represents a distinct developmental disorder of enchondral ossification and […]

Ulnar Variance – Normal Values, Measurement and Abnormalities

Ulnar variance [also called Hulten variance] refers to the difference between the levels of distal radial and ulnar articular surfaces. As we know wrist is formed by the articulation of the distal radius, distal ulna, and carpal bones. Normally, the radial articular surface lies slightly in a distal position than the ulnar articular surface. Many […]

Lumbar Discography – Indications, Procedure and Inference

Lumbar discography is an invasive diagnostic procedure that involves, instillation of iodinated contrast into the nucleus pulposus after inserting a needle under fluoroscopy. This procedure is done with an aim to get information on the morphology and integrity nucleus pulposus, vertebral endplates and annulus fibrosus. In addition to this, the measured contrast injection allows determination […]

Dynamic Condylar Screw Indications and Procedure

Dynamic condylar screw is an implant assembly that consists of a lag screw, angled barrel plate fixed to the bone [usually distal femur] by 4.5 cortical screws. DCS and DHS work on the same principle of the sliding nail that allows impaction of the fracture. This is due to the insertion of wide diameter into […]

Tuberculosis of Knee Joint – Diagnosis and Treatment

Tuberculosis of knee joint is third common osteoarticular tuberculosis after spine and hip. Knee tuberculosis or commonly called TB knee accounts for nearly 10 percent of all skeletal tuberculosis. Relevant Anatomy of Knee Joint The knee joint is the largest joint in the body. It is a superficial joint and because of its large size […]
