– 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
– Extra-articular Reconstruction: – these type of procedures are now no longer used as the primary reconstructive method for ACL tears; – some authors feel that the extra-articular reconstruction may have a role in augmenting the intra-articular reconstruction; – references: – Biomechanics of intra-articular and extra-articular reconstruction of the anterior cruciate ligament. – The effect … Read more
– See: Watson Jones Approach – Discussion: – Smith Petersen improved & revived the anterior iliofemoral approach; – entire ilium and hip joint can be reached thru iliac part of incision; – w/ this approach there is a need for extensive detachment of tendinous insertions & retraction of muscle, w/ potential damage to femoral artery and … Read more
– See: – Lateral Compartment – Deep Posterior Compartment – Superficial Posterior Compartment – Compartment Syndrome: – Discussion: – anterior compartment of the leg contains tibialis anterior, EDL, EHL, and Peroneus Tertius muscles; – compartment is primarily … 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
Discussion pathoanatomy: fibular collateral ligament is made up of three separate structures; these are not as strong as medial ligaments, since lateral support of ankle is also provide by the fibula; anterior talofibular ligament calcaneofibular ligament posterior talofibular Ligaments cervical ligaments: ref: Elongation behavior of calcaneofibular and cervical ligaments during inversion loads applied in an … Read more
Discussion varus deformity of the ankle may follow distal tibial fracture or distal tibial epiphyseal frx; deformities due to distal tibial epiphyeal injuries are often progressive; deformities due to tibial plafond injuries are usually static (from malreduction at the time of the original procedure); left untreated, the varus deformity may lead to DJD of the … Read more
(See also: Antiglide Plate) Discussion position of plate is dependent on level of frx, condition of overlying soft tissues, and the extent of comminution; Posteriorly Positioned Plate see antiglide plate: allows use of a thicker, stronger plate; less risk of wound slough; irritate peroneal tendons; distal screws obtain better purchase, since they engage a thicker part … Read more
