– Discussion: – flex the knee to 90 deg and release the anterior attachment of medial joint capsule from the tibia; – this should provide wide exposure of the interior of the knee; – at this point it should be possible to sublux tibia forward for complete visualization of the plateau surfaces; – trim osteophytes … Read more
– Discussion: – SH III frx involving avulsion of anterolateral tibial epiphysis; – occurs in older adolescents, after the middle and medial parts of epiphyseal plate has closed, but before the lateral part closes (usually 12 to 15 yrs of age); – because, this frx occurs in … Read more
– PreOp Planning: – tendon transfer is chiefly indicated for stage II tenosynovitis; – subtalar joint must demonstrate nearly a full range of inversion; – early synovectomy of the tendon sheath not only relieves discomfort but will possibly delay or prevent attenuation or rupture; – in … Read more
– Discussion: – on mortise view line formed by subchondral bone of distal tibia & medial spect of the fibula should be continuous; – articlar surface of talus should be congruous w/ that of distal fibula (called tibiofibular line); – disruption of this line indicates: … Read more
– Discussion: – see: Stress Frx Menu – proximal 1/3 of tibia is most common site for tibial stress frxs in adolescents, but in runners tibial stress frx occur near junction of middle and distal thirds; – tibia is the most frequent stress fracture location in most series in both athletes and … Read more
– Discussion: – considerations for graft placement – optimal graft angle – land marks for graft entry point – determination of graft length – retention of remnant ligament: – ref: Anterior cruciate ligament reconstruction with remnant preservation: a prospective, randomized controlled study. – Transtibial Technique: – tibial tunnel guide is … Read more
– See: Anterior Compartment: – Anatomy: – origin: lateral condyle of tibia, proximal 2/3 of lateral surface of tibia, interosseous membrane, deep fascia and lateral intermuscular septum; – insertion: plantar surface on base of first metatarsal and medial plantar surface of 1st cuneiform; – action: dorsiflexes and inverts foot at the ankle; … Read more
– Anatomy: – origin: lateral part of posterior surface of tibia, medial 2/3 of fibula, interosseous membrane, intermuscular septa and deep fascia; – mid course: – it runs in the deep post compartment and passes posterior to the medial malleolus; … Read more
– See: – Tibial Plateau Frx Menu, Rim fractures: – Discussion: – frx dislocations of tibial plateau will have assoc: – knee dislocations, and ligamentous injuries; – meniscal injuries, which are usually not repairable; – N/V injuries, increasing from 2% for type … Read more
– Discussion: – 60% of plataue frxs involve lateral plateau. – this probably is result of valgus alignment of lower extremity and fact that most injuring forces are directed laterally to medially; – frxs of medial plateau make up 15% & bicondylar lesions 25% of plateau frx; – bicondylar frxs combine any of unicondylar … Read more
