Rigid stainless steel pins of varying lengths 4 – 6 mm in diameter. Bohler stirrup is attached to steinmann pin which allows the direction of the traction to be varied without turning the pin in the bone
Point of Insertion: 2-2.5 cms proximal to the distal end of 2 nd metacarpal
Technique: push the 1 st dorsal interosseius muscle volarly and palpate the subcutaneous portion of the bone. Pass the K-wire at right angles to the longitudinal axis of the radius, the wire traversing 2 nd and 3 rd metacarpal diaphysis transversly.
Draw 1 st line from before backwards at the level of the upper pole of patella,2 nd line from below upwards anterior to the head of the fibula, where these two lines intersect is the point of insertion of a Steinmann pin
Just proximal to lateral femoral condyle. In an average adult this point lies nearly 3 cm from the lateral knee joint line
