– Discussion: – K wires should never cross at the fracture site, since this will cause rigid distraction; – K wires should cross either proximal or distal to the fracture and gain firm anchorage in the proximal and distal metaphysis; – Holding Power of the Wires: – increased penetrating ability and … Read more
– Indications: – displaced long oblique fractures, spiral frxs, or articlar fractures (> 25%) of metacarpals or phalanges; – screw fixation used w/o a plate, requires that the frx length will be at least twice diameter of the metacarpal; (lag screw theory) – a minimum of 2 screws are … Read more
– Discussion: – restoration of heel width / height requires reduction of tuberosity fragment to sustentacular fragment; – generally the tuberosity fragment needs to be brought out of varus and a medially displaced position; – key toreduction of sustentaculum talus fragment, which is almost … Read more
– Preoperative Planning: – Surgical Stratedgy: – pt in true lateral position – J or L approach w/ subperiosteal dissection off lateral wall, including calcaneo-fibular ligament (sural nerve in flap); – extension from tuberosity to calcaneo-cuboid (watch peroneals) – … Read more
– Discussion: (distal radius fracture menu and colles fracture) – volar surface of distal part of radius is slightly flattened, except for its distal margin, which slopes volarly to form a prominent ridge from which volar radiocarpal ligaments originate. – short radiolunate ligament originates off of volar margin of lunate facet and attaches to volar surface of lunate and helps maintaining stability … Read more
– Origin: flexor retinaculum and tubercle of trapezium bone; – Insertion: radial side of entire length of first metacarpal bone; – Action: flexes & abducts first metacarpal w/ medial rotation at hand; – Synergists: abductor pollicis, adductor pollicis; – Nerve: Median, C8 > T1; – Discussion: … Read more
– see distal radius fracture menu (volar Barton’s frx) – orif of distal radius fractures – Surgical Approach: – standard volar approach: – most indicated for simple extra articular fractures and when there is absence of ulnar comminution / displacement: – incision starts at thenar crease of palm, curves toward middle of forearm, w/ … Read more
– Treatment Options: – percutaneous pinning w/ 1.6 mm or 2.00 m K wires in small fragments; – ref: Complications of smooth pin fixation of fractures and dislocations in the hand … Read more
this is a test . the word finger should origin: hamulus of the hamate bone and flexor retinaculum; insertion: entire length of ulnar border of 5th metacarpal; action: flexes and slightly rotates the 5th metacarpal; helps to cup the palm of the hand; synergists: flexor digiti minimi brevis, abductor digiti minimi; nerve … Read more
