– Discussion: – it is not a neuroma but a perineural fibrosis and it was not first accurately described by Morton but by Durlacher, a chiropodist in 1845; both Thomas G. Morton (1876) and Thomas K. Morton (1892) mistook it for a painful affection of the fourth MTP articulation – it is a type of nerve compression … Read more
– Discussion: – most common pattern of motor branch of median nerve is extraligamentous take off from main branch of median nerve (distal to TCL in 50% pts) – in 30% of pts motor branch exits proximal to TLC; – in 20% of pts motor branch exits distal to TLC; … Read more
– See: MP joint in RA – Planning: – indications: – irretrievable articular cartilage damage; – volar subluxation; – dislocation are indications for surgery; – cautions: – cervical spine … Read more
– See: – Plating Techniques – Monteggia Fractures in Children – Discussion: – Giovanni Monteggia (1814) first described frx of proximal 1/3 of ulna in association w/ anterior dislocation of radial head; – hence dislocation of radial head w/ frx of proximal 1/3 of ulna is known as Monteggia’s deformity. – Mechanism: – proposed … Read more
– See: Ankle Sprains – Discussion: – indications: – clinical symptoms are chief indications (radiographic findings may or may not correlate w/ the severity of the sprain and ankle dysfunction; – associated injuries: – longitudinal tear of the peroneus brevis: – contra-indications: – fixed heel varus; – obese patients; – Radiographs: … Read more
– See: Watson Jones Approach Smith Peterson Approach – Discussion: – in direct lateral approach, a curvilear split is made thru the anterior portion of the gluteus medius and vatus muscles, in order to gain access to the anterior face of the hip joint; … Read more
– Discussion: – modified procedure includes release of adductor hallucis, transverse metatarsal ligament, and lateral capsule combined w/ excision of medial eminence and plication of the capsule medially; – this procedure was modified to retain the lateral sesamoid, which helps to prevent hallux varus (which as common w/ original Mcbride bunionectomy); – as this procedure attempts to … Read more
– See: Monteggia Fractures in Adults – Discussion: – all four types of Monteggia frx dislocation are pertinent to children, including Monteggia equivalents; – diff dx: Monteggia equivalent (w/ fracture of proximal radius rather than dislocation of the radial head); – Classification: – type I: – anterior dislocation of the radial head w/ apex anterior … Read more
– Discussion: (RTC menu) – mobilization is often required for massive tear; – simply closing extensive tear will not suffice if atrophied muscles are not contracting adequately and if excessive tensions placed on repaired cuff cause reinjury; – repair of good quality rotator cuff tissue is esp important in achieving an optimal result; … Read more
