– Discussion: – following lengthening or rupture of tibialis posterior, pt will develop fixed hindfoot deformity w/ hindfoot valgus and forefoot in abduction; – if site of maximal deformity is at talonavicular joint, then an isolated talonavicular or talonavicular & calcaneocuboid may be performed; – sub-talar arthrodesis: – w/ more … Read more
– Discussion: – inflammation causes tenosynovitis and elongation; – hindfoot remains supple and is reducible; – pt has flexible flat foot, & w/ removal of weight, foot resumes its normal arch; – it is essential to distinguish the supple type II lesion from the type III lesion … Read more
– Discussion: – involves injury to distal tibial ephiphysis, & are due to plantar hyperflexion or external rotation force; – presents as SH II, SH III, or SH IV type injury of distal tibia which may disrupt articular surface as well as physis; – Salter Harris III: … Read more
– See: rupture of tibialis posterior – Dicussion: – tendinitis is present but tendon remains at its normal length; – in a young patient consider accessory navicular; – Non Operative Treatment: – arch supports, rubber-soled shoe w/ quarter-inch medial heel, sole wedge, UCBL; – immobilization in a … Read more
– Discussion: – key to stability of ankle mortise is posterior syndesmotic ligament complex, ligament or posterior tibial tubercle or malleolus; – presence of a posterior lesion always indicates degree of instability, whether or not the medial structures are disrupted; – no matter what mechanism, instability must be assumed … Read more
Discussion conditions include: AS Reiter’s Syndrome Psoriatic Arthritis Inflammatory Bowel Disease typically involves the axial skeleton; affected areas heal w/ fibroblastic proliferation followed by new bone formation; pathogenesis of these disorders is unknown except for Reiter’s syndrome, which is generally believed to result from aberrant host response to a pathogenic microorganism; Labs RF is negative; HLA-B27 phenotype: … Read more
– Discussion: Split Compression / Type II Fractures: – split fragment from articular surface along w/ depressed area similar to that of local compression frx; – lateral wedge frx is combined w/ varying deg of depression of adjacent remaining wt bearing portion of lateral tibial plateau; – depression is usually located anteriorly or centrally; … Read more
– Discussion: Tibial Plateau Frx Menu – in most split frxs, large articular frag has separated in coronal plane from posterior portion of medial tibial plateau; – fragment rarely separates from lateral plateau or from anterior aspect of either plateau; – 22% of these frxs will also have assoc intercondylar eminence … Read more
