Data Trace Editor – See: – Primary Flexor Tendon Grafting – Pulley Reconstruction – Prosthetic Grafts – Discussion: – indicated for delayed or neglected flexor tendon injuries, tendon rupture following previous attempted repair, and in some cases is indicated for zone II tendon injuries; – probably in most cases, … Read more
– 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: – this is terminal phase of necrotic process, and is characterized by progressive loss of articular cartilage & development of acetabular osteophytes; – radiographic picture is of OA superimposed on a deformed femoral head; – movement is diminished until only a small range of flexion remains
– 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: – this stage is characterized by pathognomonic appearance of sequestrum on the radiograph; – this appearance is often preceded by changes representing a transition between stage II and III; – these are crescent line due to subchondral frx, & segmental flattening of femoral head; – sequestrum later becomes … 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
– Discussion: – this extends over several months and sometimes much longer; – clinical signs persist, or worsen, & radiographs show changes in trabecular pattern of femoral head; – sclerosis may be diffuse, in localized areas, or in a linear arc which is concave superiorly
– 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
– See: Radiographic Findings – stable intertroch frx is one that when reduced has cortical contact w/o gap medially and posteriorly; – this contact will prevent frx displacement into varus or retro-version when forces are applied to proximal femur; – medial cortices are not comminuted & there is no displaced frx of lesser trochanter
– Criteria for Stable Burst Frx: – neurologically intact; – posterior arch remains intact: – pedicle widening implies post arch disruption w/ instability; – less than 25 to 35 deg of kyphosis; – less than 50% anterior body height collapse: – Discussion: … Read more
