Plate Fixation of Olecranon Fracture
– Discussion: (see olecranon frx menu) – indicated for comminuted olecranon frx and frx which occur at or distal to the coronoid process; – if frx extends distally past midpoint of trochlear notch, it no longer represents only a disruption of the triceps mechanism but also comprimises the stability of elbow in withstanding varus & … Read more

– Discussion: – arises from posterior aspect of profunda femoris artery; – they course directly against linea aspera of the femur & tendonous insertions of adductor muscles; – inferior gluteus artery gives twigs to upper ends of muscle attaching to ischial tuberosity and transverse branch of MFCA appears … Read more
Pelvic Osteotomy for DDH
– See: DDH: – Indications for Treatment: – age: pelvic osteotomies are usually performed between ages 3-8 years; – in children > 3 years, open reduction, femoral shortening, & acetabular redirection will provide concentric reduction, will reduce AVN, & will achieve a functional range of motion; – some will even consider pelvic osteotomy in children as … Read more
