– 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: – 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: – 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
– 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: – 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
– Discussion: – scapholunate advanced collapse (SLAC) refers to a specific pattern of osteoarthritis and subluxation which results from untreated chronic scapholunate dissociation or from chronic scaphoid non-union; – degenerative changes occur most often in areas of abnormal loading; – radial-scaphoid joint is involved initially, followed by … Read more
