– 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: – allows acces to ankle joint, talus, & other tarsal bones and joints; – it does not allow access to the navicular and 2nd and 1st cuniforms; – avoids all of the important vessels and nerves; – dissection procedes between the peroneus tertius (deep peroneal nerve) and the peroneus brevis (superficial peroneal … 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
– Discussion: – most important portal, initial site for scope insertion; – structures that are difficult to see: – PCL – anterior portion of lateral meniscus – posterior … Read more
– See: – stabilizers of the shoulder – shoulder capsule – Discussion: – originates as a portion of fibrous glenoid labrum anteroinferiorly; – there are two subdivisions of this ligament: an anterior and posterior bands along with the intervening axillary pouch; – antero-inferior portion of normal … 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
– 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
– 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
– See: Hyperflexion Injuries – Discussion: – partial or complete tear of posterior ligaments w/ varying degrees in widening of the interspinous and interlaminar spaces, as well as subluxation, but not dislocation of Facet Joint; – hyperflexion sprain injury may include mild anterior subluxation of involved vertebral body; – this subluxation … Read more
– See: – Anterior Drawer Test – Anatomy: – it connects anterior fibula to neck of talus; – ligament is thickening of ankle capsule that extends short distance from anterior edge of distal part of fibula to talar neck, anterior to its lateral articular facet; … Read more
