– See: Smith Peterson Approach – Discussion: – major problems with the Watson Jones technique are dealing w/ gluteus medius & minimus, which lie over anteior capsule and must be damaged or cut to obtain adequate exposure; – original Charnely technique used anterolateral approach w/ pt supine, osteotomy of greater troch, … Read more
Discussion defined as excessive forward rotation of tibial plateau w/ excessive lateral opening of the joint; there is excessive internal rotation of tibia on femur in flexion; as knee extends, subluxation is reduced by the bony stability, and a jerk is noted which is basis for the pivot shift test; disrupted structures disruption of ACL disruption … Read more
– See: – Arthroscopic Reconstruction – Historic Operations – Revision Bankart Procedure – Bankart Repair: – reattachment of the capsule and glenoid labrum to the glenoid lip; – subscapularis is carefully divided to expose the capsule, and is reapproximated without any overlap or shortening; – PreOp Eval: – rotatory stress test for anterior instability; – … Read more
– Seee: Anterior Pelvic Injuries – Discussion: – symphyseal diastasis and/or longitudinal rami fractures; – these injuries result from relatively anterior or posterior forces applied to the anterior or posterior superior iliac spine areas; – this gives rise to forces that tend to disrupt anterior pelvis, either by fracturing … Read more
– Discussion: – see frx dislocations of the hip – comprise 10-15% of traumatic dislocations of hip; – occur when knee strikes dashboard w/ thigh abducted, falls from ht, or from a blow to the back of pt while in squatted position; – neck of femur or greater trochanter impinges … Read more

A Decision Analysis. – Diagnosis of femoral neck fracture associated with femoral shaft fracture: blinded comparison of computed tomography and plain radiography. – IM nailing of … Read more
– See: Anterior Approach to the Humerus Axillary Approach: Posterior Approach Posterior Approach to Humerus Surgical Approach for Proximal Humeral Fractures Positioning and Draping: supine or beach chair; small soft bolster is placed beneath the shoulder blades to protract the shoulder; head is stabilized to prevent hyperextension and subsequent brachial plexus palsy; place patient in … Read more
– Discussion: – non-neoplastic expansile lesion consisting of blood filled spaces separated by connective tissue septa containing bone or osteoid and osteoclast giant cells – etiology unknown – may be primary or secondary; – an uncommon expansile osteolytic lesion of bone consisting of a proliferation of … Read more
Discussion distal epiphysis includes entire articular surface of distal end of femur & serves as origin of part of gastrocnemius muscle; epiphyseal center of distal aspect of femur is present at birth in newborns, & it expands rapidly to fill both condylar regions. collateral ligaments originate from distal femoral epiphysis & insert on proximal tibial … Read more
– See: Arterial supply to Femur – Embryology of Proximal Femur: – upper end consists of head, neck, & greater & lesser trochanters at junction of the neck with the body; – develops from 4 separate ossification centers; – head forms roughly two-thirds of sphere whose surface is articular except for fovea capitis femoris where … Read more
