– See: Posterior Approach for Pelvic Frx – Indications for Use: – isolated posterior wall & posterior column frxs; – allows access to posterior column and posterior wall only, but exposure is limited proximally by superior gluteal vessels and greater trochanter; – isolated transverse frx (as well … Read more
– See: – Anterior Approach to Humerus – Posterior Approach to the Elbow; – Plate Fixation of the Humerus; – Indications: – Distal Third Humeral Fractures: – Humeral Mid-Shaft Frx are also amenable to the posterior approach if the formal approach is modified (see below); … Read more
– Discussion: – S shaped skin incision is made, extending along the posterior border of biceps and its tendon on the upper lateral side of popliteal fossa, then transversely across the fossa and finally along lower medial side of fossa posterior to semitendinosus tendon; – skin flaps are retracted and the deep fascia is incised … Read more
– See: – Associated Transverse and Posterior Wall Frx – Classification and Column Theory – Discussion: – most common type of acetabular frx (up to 50% of acetabular fractures will contain a posterior wall fragment); – posterior wall frxs involve the posterior articular surfaces, often w/ retroacetabular … Read more
– 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
– See: EMG Menu: – Discussion: – associated w/ muscle denervation or myopathy; – these are often found in assoc w/ fibrillation potentials, but tend to procede them in appearance after a nerve lesion
– 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
Polarus Implant Features A patented array of 5.0 mm proximal holes to allow for secure fixation of the most common multi-part proximal humeral fractures. Each screw is designed with deep cancellous threads for added holding power. Strategic screw locations help avoid the axillary nerve and other key structures. Distal interlocking is achieved with up … 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
