– Discussion: – injury must occur to both interosseous and capsular ligaments for rotational instability of the scaphoid to occur; – dorsal approach to the wrist: – reduce scaphoid into the extended position; – surgeons gloved finger presses the distsal pole of scaphoid into an extended position; – K wire is inserted … Read more
– Discussion: – see anatomy of the scapula – most common scapular frx are frx of the body, followed by the neck, glenoid, and acromion; – associated injuries: seen in upto 80-90% of patients; – pulmonary injuries and pneumothorax (23%) and pulmonary contussion; … Read more

– See: Avascular Necrosis of the Scaphoid – Discussion: – often result from undiagnosed or undertreated non displaced scaphoid fractures, especially when associated w/ carpal instability; – even when found as late as 6 mo after the injury, frx of scaphoid, esp at the waist and distal location, may go on to heal; … Read more
– Discussion: – indicated for patients w/ delayed unions or non unions of scaphoid waist; – cautions: distal-waist fractures may not be amenable to this form of fixation if the screw threads cross the fracture site; – Technique: – see: volar surgical approach: – may result in … Read more
– Work Up for Scaphoid Fracture: (w/ discussion) – clinical differential diagnosis: – distal radius frx – transscaphoid perilunate dislocation: – scaphoid impaction syndrome – radiographs and determination of stability (CT scan) – non diagnostic radiograph (bone scan) – tubercle frx – transverse waist frx – proximal pole frx – treatment: … Read more
– Discussion: – indicated for arthritic RU Joint w/ limitation of motion; – may be useful for rheumatoid patients w/ ulnar translocation, as well as the caput ulna syndrome; – procedure involves resection of a portion of distal ulna shaft and fusion of the ulnar head to the radius; … Read more
origin: anterior tubercles of the transverse process of the 2nd to 6th cervical vertebrae; insertion: scalene tubercles on anterior superior surface of the 1st rib; action: – acting unilaterally, flexes and rotates cervicals and raises first rib; – when acting bilaterally, flexes the neck; nerve supply: anterior branches, C5, … Read more
origin: posterior tubercles of the transverse process of 2nd to 7th cervical vertebrae; insertion: superior surface of the 1st rib behind subclavian groove; action: acting unilaterally, flexes and rotates cervical vertebrae; raises first rib; when acting bilaterally, flexes the neck; nerve supply: posterior branches of anterior primary rami of C3, C4; lateral muscular … Read more
