– 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
– Discussion: – growth-remaining method – straight-line graph method – arithmetic method is the simplest, but least accurate. – proximal femoral physis:: – 4 mm / yr (1/8 in/yr) – distal femoral physis: – … Read more
– Discussion – see: Bone Tumor Menu – Types of Metastatic Carcinoma: – breast cancer – renal cell ca – prostatic cancer – lung carcinoma – thyroid cancer: – may cause heavy bleeding if disturbed (consider need for embolization prior to biopsy … Read more
– Discussion: – for evaluation of both the patella and trochlea surfaces of femur; – disadvantages: – this view does not necessarily predict which patients will show functional improvements w/ surgical realignment; – as pointed out by O’Neil (1997) some patients … Read more
– See: Medial Approach: – Discussion: – medial epicondyle is common origin of several flexor muscles of hand and wrist; – when medial epicondyle is frxed, flexor muscles pull fragment distally; – during surgical procedure care must be made to protect ulnar nerve; – Fixation Stratedgy: – … Read more
– See: – Pediatric Elbow Injuries – distal humeral physeal separation – lateral condyle frx, pediatric – supracondylar frx of humerus – Discussion: – third most common pediatric elbow frx (5-10%) (behind supracondylar and lateral condylar fractures); – most common between ages of 9 … Read more
– Discussion: – allow visualization of medial epicondyle, trochlea, and ulnar nerve are – approach is used for a total elbow arthroplasty; – proximally the interval lies between the brachialis and triceps, where as distally the interval lies between the brachialis and MCL; – avoid … Read more
– Discussion: – malleolar screws with cortex thread, shaft & trocar tip have limited use in the metaphyseal area, distal humerus, trochanteric area, & sometimes in the ankle, where the bone is rather dense; – malleolar scew has a smooth shaft and is partially threaded; – … Read more
– Theoretical Considerations: – Discussion of Limb Lengthening: – Distraction Histiogenesis: (osteoclasis): – Ilizarov Menu – Technique: – ring characteristics: – w/ the original Ilizarov technique, only two rings (each with drop wires) were used; … Read more
– See: Fracture Dislocation: – Discussion: – pure avulsions of the lesser tuberosity are rare; – pressence of this frx raises possibility of assoicatted posterior dislocation; – lesser tuberosity fragment consists of the lesser tuberosity with its attached subscapularis muscle; – avulsion of this frag may allow … Read more
