2. FALSE JOINT (PSEUDARTHROSIS)

A false joint (pseudarthrosis) is a persistent abnormal mobility within any part of a bone diaphysis. False joints are divided into two groups: congenital and acquired. The formation of congenital pseudarthroses is associated with intrauterine pathology and is rare. Acquired false joints develop as a consequence of fractures, most commonly open ones. In this condition, a bony callus fails to form between the bone fragments. Clinical Features include painless mobility between the bone fragments in the anteroposterior and lateral directions, Atrophy of the surrounding Muscles, sometimes deformity of the limb segment, and its functional impairment. The primary causes of acquired pseudarthrosis include errors in fracture management and The Development of post-traumatic Osteomyelitis, which frequently occurs against the Background of systemic conditions (endocrine disorders, infections, or electrolyte imbalance).
