– See: Hetertopic Ossification of the Elbow: – Discussion: – most indicated for flexion contractures of the elbow (w/o extension contracture); – disadvantages: – some patients may gain extension but will loose flexion (especially if they are casted in extension); … Read more
– Discussion: – strong and well-defined, arise from antero-inferior surface of medial epicondyle and inserts at the sublimis tubercle, adjacent to the joint surface; – primary constraint to valgus instability; – in flexion, MCL provides 54% of valgus stability; … Read more
– See: – Anterolateral Approach to Forearm – Forearm Flexors – Plating Techniques – Radial Shaft Fractures: Discussion – Discussion: – anterior approach of Henry utilizes interval between brachioradialis (radial nerve) & pronator teres (or FCR distally, which are innervated by the median nerve); – … Read more
– See: – Anterior Approach to the Shoulder – Discussion: – with plate fixation of the humerus, the anterior approach is preferred for proximal and mid-diaphyseal frx w/ application of plate to anterolateral aspect of the humerus (see humeral shaft fractures); – interval lies … Read more
origin: posterior surface of lateral epicondyle of humerus; insertion: lateral side of olecranon process and posterior surface of proximal portion of ulna; action: extension and pronation of the forearm at the elbow; nerve supply: radial, C5, C6; synergist: triceps brachii The aconeus muscle flap: its anatomy and clinical application.
– 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
– Discussion: – together w/ proximal portion of the coronoid process, olecranon forms greater sigmoid notch of the ulna, a deep depression that serves as articulation w/ trochlea that serves as the articulation w/ trochlea which allows motion only in anteroposterior plane and provides … Read more
– See: role of knee joint in locomotion and mechanical axis – Discussion: – bones forming the knee joint are femur, tibia, & patella; – both left and right femurs converge toward knee and each tibia is nearly vertical, femur and tibia meet angle of some 5-12 deg; … Read more
Anatomy & Sites of Compression of Cubital Tunnel – Discussion: – cubital tunnel extends from medial epicondyle to olecranon; – it serves as the major contraint for the ulnar nerve as it passes behind the elbow; – w/ flexion the cubital tunnel becomes taunt, and with extension the cubital tunnel becomes lax; – aponeurotic roof … Read more
– vascular supply to the humeral head – Two Part Articular Segment Displacement: – fracture plane is through the anatomic (not surgical neck); – anatomic neck represents the old eiphyseal plate; – surgical neck represents the weakened area below the tuberosities and head approximately 2 cm distal to the … Read more
