– Anatomy: – three posterior divsions of brachial plexus form posterior cord: (C5 , C6 , C7, C8, T1) – upper subscapular nerve to subscapularis – thoracodorsal to latissimus dorsi – lower subscapular nerve to subscapularis and teres major … Read more
– See: Posterior Approach to the Humerus; – Discussion: – considered to be the most versatile approach to the elbow; – most surgeons use straight longitudinal incision, which avoids olecranon tip, by shifting the incision slightly laterally or medially; – Variations of Posterior Approach: – Transolecranon Osteotomy … Read more
– See: – AP view – Carpal height & Carpal height ratio – Clenched Fist AP – Radial Inclination – Radial Length & Width – Ulnar Variance – X-ray for Distal Radius Frx – Discussion: – AP View is prefered for … Read more
– See: – Anterior Approach to Humerus – Posterior Approach to the Elbow; – Plate Fixation of the Humerus; – Indications: – Distal Third Humeral Fractures: – Humeral Mid-Shaft Frx are also amenable to the posterior approach if the formal approach is modified (see below); … Read more
– 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frx which occur at or distal to the coronoid process; – if frx extends distally past midpoint of trochlear notch, it no longer represents only a disruption of the triceps mechanism but also comprimises the stability of elbow in withstanding varus & … Read more
– Considerations: – see plate fixation theory and bone healing with plate fixation; – candidates for ORIF are humeral shaft frx w/ no comminution w/ enough of an oblique component to allow lag screw fixation; – in contrast, comminuted transverse fractures may be less satisfying for fixation, and may require bone grafting; – w/ transverse … Read more
– Discussion: – one of several causes of heel pain; – the pain is located somewhat more distally than in other causes of heel pain syndrome – symptoms include gradual onset of pain at the origin of the plantar aponeurosis and 1 cm distal to this area … Read more
– See: Function and Activity after TKR – Post Operative ROM: – most important factor predicting ultimate ROM is range of motion before surgery; – ref: Range of Motion Correlates with Patient Perception of TKA Outcome. – patients with significant stiffness before surgery will have the most difficulty gaining range of motion; … Read more
Discussion pigmented villonodular synovitis is a slow growing, benign, and locally invasive tumor of the synovium; location: most often involves the knee (also in hip, ankle, elbow, etc.); always consider PVNS in a younger patient with unexplained hip pain; acute episodic attacks of pain and swelling may occur; patients may have mechanical symptoms (locking and … Read more
– Dicussion: – assess for swelling and tenseness of the forearm compartments; – assess carrying angles of the affected and non affected arms; – r/o neurologic deficits – median nerve injuries are more often associated w/ posteromedial displacement; – … Read more
