– Assess ISS: – w/ multiple injuries (Pelvic Frx) consider supine position and use of universal femoral distractor; – Rotational Alignment – 45 deg Lateral on Flouro Table: – indications: – include ipsilateral femoral and acetabular frx or vertical unstable pelvic fracture; … Read more
– Supine – No Traction: – easiest method is supine position, w/ several rolled towel/blanket bumps placed side by side which elevates the fractured extremity above the other side (which is necessary inorder to get a lateral view on flouro), and which facilitate knee flexion (which is necessary for entry into the … Read more
– See: Osteolysis and Insertion of Polyethylene – Discussion: – originally Charnley used high density polyethylene and later this was changed to ultrahigh molecular weight polyethylene – impact strength of UHMWPE is higher than that for HDPE and the density of UHMWPE is much lower than … Read more
– See: differential diagnosis of posterior fossa masses – Discussion: – popliteal artery is the continuation of superficial femoral artery at hiatus of the adductor magnus muscle; – artery is anchored proximally by tendinous insertion of adductor magnus upon the medial femoral epicondyle; – it runs posterior to the distal … Read more
– Anatomy: – origin: – lateral condyle & posterior horn of lateral meniscus fibular head; – popliteus muscle has 3 origins, strongest of which is from lateral femoral condyle, just anterior and inferior to the LCL origin; … Read more
– Discussion: – traditionally, subtalar arthrodesis has been performed w/ ankle in neutral dorsiflexion / plantarflexion & neutral or slight valgus; – by placing calcaneus in 5 degrees of valgus, transverse tarsal joint remains supple and provides mobility to the forefoot; – in presence of fixed forefoot equinus, however, … Read more
– See: – Equinovalgus – Anterior Horn Cell Disorders: – outside links: – Polio Resources: – Lincolnshire Polio Network – Discussion: – caused by death of anterior horn cells of … Read more
– Discussion: – see plating of tibia fractures and synthese products – six cortices should be held proximal to most proximal fracture line, and lag screws should be used when frx lines cross; – when using medial plate, additional anteroposterior lag screw fixation may be needed to secure posterior lip frx; … Read more
– Discussion: – plating techniques and synthese products – primarily indication for plates and screws is a displaced intra-articular frx of tibia, involving either knee or ankle; – main disadvantage is skin necrosis and resultant infection; – malunions and mal-non-unions are other indications; – Operative Techniques for Proximal Tibial Fractures: … Read more
– See: Orthotics for the Foot: – Plantar Keratosis: – this callus is a circumscribed keratotic area which may or may not be associated with a hammered great toe; – kerkatosis often resembles verruca plantaris, for which it is mistakenly treated until the keratosis breaks down and ulcerates or leaves a permanent … Read more
