Developmental dysplasia of the hip is a developmental disorder where the hip joint is not formed normally due to abnormal growth of the hip joint. Dislocatable Hip (dislocate on provocation) –>Instability (varying degree) –>Dislocated Hip (dislocated at birth) Teratological dislocation: Developmental dysplasia of the hip that occurs early in-utero and is associated with syndromes such […]

The rotator cuff reinforces the joint capsule except at the rotator interval (area between the anterior part of the supraspinatus and upper border of subscapularis) The most vulnerable area of tendon failure are deep fibers ( glenohumeral joint side) which is on the insertion of tuberosities Rotator cuff disruption Classifications Partial thickness (more painful)/ Full […]

Recurrent dislocation of the patella occurs episodically as the force is generated, and disturbs the patellofemoral kinematics. Important terms: Medial patella-femoral ligaments Trochea hypoplasia Patella Alta TT-TG ( Tibial tuberosity- Trochlear groove ) Definitions: Congenital Patella dislocation occurs since birth Acute patella dislocation is an acute con Old unreduced patellar (permanent) dislocation, where dislocation is […]

Vascular Supply of proximal femur changes as the age advances and has clinical significance as its injury can leads to avascular necrosis of femoral head. It is important in pathogenesis of Perthe’s disease. At base of femoral neck and at the level of capsular attachment, extracapsular ring of attachment is formed. In which, Posterior portion […]
