– See: – Anterior Subluxation: – Ligamentous Instability: – Discussion: – the flexed view is usually most helpful in detecting ligamentous injury that is not apparent on the neutral view – determines the integrity of the supporting soft tissues and ligaments, as well as the … Read more
– See: boutonniere injury – Discussion: – flexion contracture: – treatment should start with static or dynamic splinting; – in the study by Bruser, et al (1999), a midlateral incision yielded a more normal ROM than a palmar incision; … Read more
– See: – Finger Tip Injuries – Brunner Type Incisions: – The zig-zag volar-digital incision for flexor tendon surgery. – Midaxial Incision: – indications: septic arthritis of IP joints and MP joint of thumb; – site for placing midaxial incision is performed by flexing finger & marking the … Read more
– See: – Phalangeal Injury – Menu – Thumb Defects: – Moberg Flap – Nail Bed Injuries: – if injury damages the distal phalanx, particularly when the damage extends into germinal matrix, the nail will probably be irregular and … Read more
– Finkelstein’s test: – ask patient to make a fist over his thumb, and ulnarly deviating wrist – sharp pain at this site is produced by active extension and abduction of the thumb against resistance; – Differential Diagnosis: – DeQuervain’s tenosynovitis must be differentiated from degenerative arthritis & trapeziometacarpal joint; … Read more
– Discussion: – results from a defect is somatic mutation in the gene coding for alpha subunit of Gs, the G protein that stimulates cAMP formation; – overproduction of cAMP, causes overexpression of c-fos, which regulates proliferation and differentiation of osteoblasts and osteoclasts; – results in … Read more
– Discussion: – goal: ream close to endosteal cortex, which has strongest cancellous bone; – enter medullary canal w/ curet, & ensure that there are no perforations; – this is esp important w/ osteoporotic bone; – to enlarge medullary canal of diaphysis, use … Read more
– See: – x-rays for femoral neck fractures – technique of closed reduction – Acceptable Reduction: – poor reduction of femoral neck frx interferes w/ blood supply to femoral head & decreases apposition of bone between bone fragments; – reduction should leave neck-shaft angle between … Read more
– See: Accetable Reduction Parameters – Discussion: – always attempt closed reduction before open reduction; – evaluation of the lateral x-ray after reduction to evaluate posterior comminution of the femoral neck is critical; – posterior comminution leads to the loss of a butressing effect posteriorly, w/ subsequent loss of reduction … Read more
