– 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 … Read more
– Discussion: – condition is a part of the spectrum of the bowing-pseudarthrosis disorder seen in neurofibromatosis; – tibial pseudarthrosis may be present at birth, or it may present later on following a frx from an anterolaterally bowed tibia; – this disorder should not be confused … 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
– See posterior tibial artery – Anatomy: – anterior tibial artery passes from behind through gap above interosseous membrane to enter anterior compartment of leg and supply its muscles; – as it crosses membrane, it gives off a recurrent branch; – ref: The risk of injury to anterior tibial artery in posterolateral approach to … 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
– Bony Impingement: – pts who have persistent pain in anterior aspect of ankle & who have anterior tibiotalar spur evident on a lateral roentgenogram need additional diagnostic evaluation and management; – extreme dorsiflexion required by the demiplie position in ballet can lead to impingement of anterior lip of … Read more
– Discussion: – Anterior Talofibular ligament is the primary restraint in anterior drawer test; – testing of ankle in 10 deg of plantar flexion results in greatest amount of translation, although one cadaveric study showed that maximum anterior excursion occurs in dorsiflexion; – injury of the calcaneofibular lig does not increase amount of the anterior drawer; … Read more
Anterior Cruciate Ligament ‐ Anterolateral Ligament: Let’s Stick to the Facts! – Discussion: – anatomy of ACL – biomechanics of ACL – epidemiology_of_ACL_injuries – mechanism: ACL Tear – natural history of the ACL-deficient knee – partial ACL injury – pediatric ACL injuries – Evaluation … Read more
