– See: Lisfranc’s Frx – Anatomy of the Midfoot – Radiographs: – w/ questionable injury, consider wt bearing AP view to assess 1-2 interval; – if standing AP is unacceptable to the patient then consider CT scan; – abudction stress AP: … Read more
– Discussion: – mechanism of injury: – distinguish between high velocity injuries verus low velocity injuries (as this reflects incidence of vascular and nerve injuries); – w/ low-velocity knee dislocations occurance of vascular injury is about 5% and nerve injury is about … Read more
– Discussion: – trapezius and serratius anterior stabilize scapular base from which the arm operates; – trapezius, which arises from spinous processes of cervical and thoracic vertebrae & inserts on spine of scapula and acromion, is innervated by spinal accessory nerve and branches from third … Read more
– See: – Associated Transverse & Posterior Wall Fracture – T Shaped Fractures – AO Foundation Transverse Fracture – Discussion: – transverse frxs extend across both the anterior and posterior columns; – frx divides the innominate bone into superior segment containing acetabular roof … Read more
– Discussion: – simple transverse frxs w/out comminution may have delayed healing which requires close observation to avoid distraction & angulation; – this is especially true if a gap exists at frx site which cannot be closed by non operative means; – Closed Reduction: – note these … Read more
– Discussion: – rupture of transverse ligament is destabilizing injury that can occur in isolation or with atlantoaxial subluxation or an atlas fracture; – transverse ligament is primary restraint to anterior translation of atlas in relation to the lower cervical … Read more
– Discussion: – usually result from direct blow; – presents w/ dorsal angulation & increased palmar displacement of metacarpal heads because of deforming force of interosseous muscles and long flexor muscles, which are volar to the fracture plane; – more proximal frxs (ie, shaft frx) are more likely to … Read more
– Discussion: – relatively short lived acute inflammatory process; – usually seen in boys aged 2 to 10 years; – frequently follows an upper respiratory tract infection; – most common cause of painful hips in childhood; – is a diagnosis of exclusion; – … Read more
– Discussion: – popularized by McKittrick et al. (1949) and by Pedersen and Day (1954) – indicated for trauma, tissue loss, infection, and gangrene (limited to toes and not the web space in diabetics); – TMA requires shoe modifications & inserts w/ forefoot space replacement. – indicated for … Read more
