– Discussion: – anatomy and ligamentous contraints: – ligaments of the wrist – SL interosseous ligament – SLD is most common and most significant ligament injury of wrist; (carpal instability); – risk factors: ulna minus configuation, slope of radial articular surface, and lunotriquetral coalition; – spectrum of injury: (increasing severity) – ref: Association of lesions of … Read more
– 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: Radiographic Studies for Impingement Syndrome – Discussion: – used in the impingement patient to evaluate the subacromial space and the supraspinatus outlet from lateral view; – Technique: – position the patient for a scapular lateral view and tip the beam caudally 5 to 10 degrees The … 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
– Discussion: – scaphoid shift maneuver is performed by placing the examiner’s thumb over palmar aspect of the distal pole of the scaphoid; – constant pressure is maintained with the examining thumb as the wrist is moved from a position of extension, ulnar deviation to flexion, radial deviation, and back again; … Read more
