– Discussion of Treatment of Recent Dislocations and Fracture-Dislocations of the Shoulder – maintains that biceps and subscapularis muscle offers the chief resistance to reduction; – in anatomic position, w/ humerus at side, direction of various muscles around shoulder girdle seems to completely haphazard; – constancy of this effect must be attributed … Read more
– See: – Characteristics of Phalangeal and Metacarpal Fracture: – Injury to the Phalanges: – Discussion: – important deforming force is the insertion of central slip into the dorsum of the base of the middle phalanx & insertion of flexor digitorum superficialis volarly; – … Read more
– Discussion: (see: dynamic instability); – type of non dissociative carpal instability; – capitolunate joint has high potential for instability, since it is mainly stabilized only by radiocapitate ligament (and captiotriquetral ligament, to a lesser degree); (see wrist ligaments); – may result from malreduced radial styloid frx, or any … Read more
– Discussion: – extends lateromedially from mid-palmar septum to hypothenar eminence; – extends proximodistally to level of superficial palmar arch; – dorsally the bursa is bordered by the middle, ring, (and ? little) finger metacarpals and palmarly by the flexor tenons and lumbricals; – bursa functions to … Read more
– See: Orthopaedic Infection Menu: and risk factors for TJR infection – Pre-Admission Considerations: – removal of hardware prior to joint arthroplasty: – High incidence of early periprosthetic joint infection following THA with concomitant or previous hardware removal – Hospital and OR Considerations: – perioperative oxygen – normothermia: – Perioperative normothermia to … Read more
– Discussion: – displacement of metacarpal shaft fractures is prevented by intermetacarpal ligaments and intrinsic muscles; – the border metacarpals (thumb, index, and little) are not supported as well as the ring and long metacarpals and are therefore more likely to displace; – effect of shortening: … Read more
– See: Extra-articular Thumb Metacarpal Fractures – Discussion: – interosseous muscles & intrinsically strong carpometacarpal capsular and interosseous ligaments provide intrinsic stability to extra-articular fractures at the metacarpal bases; – mechanism of frx of little CMC: – stability of CMC joint derives from articulation w/ carpal … Read more
– See: MP joint injuries – Discussion: – often badly comminuted; – consider a short period of splinting followed by early active motion; – this may mold the articular surface by using the soft tissue sleeve; – early motion will also prevent joint stiffness, but loos of … Read more
– carpometacarpal fracture dislocation – dislocation of MP joint: – complex dislocations of the MP joint – simple dislocations of the MP joint – thumb MP joint dislocation – metacarpal head frx – metacarpal neck fracture – metacarpal shaft fractures – MP joint locking – rheumatoid arthritis: MP joint – MP joint arthroplasty – MP … Read more
– See: metacarpal frx menu – Discussion: – frxs through neck & shaft of metacarpals usually angulate w/ apex dorsal, displacing the metacarpal head into the palm; – ring and little neck frx: (see boxer’s frx); – corresponding CMC joints are mobile (in contrast to 1st & 2nd CMC) w/ flexion extension arc of between … Read more
