Posterior to anterior distal locking of humeral intramedullary nails
TECHNIQUE Humeral nailing is performed with the patient in the lateral decubitus position with the image intensifier at 90o to the patient (Fig 1). During freehand distal locking, the patient’s arm rests on his or her body and the forearm is rested on the anterior pelvic support on sterile padding. By changing the amount of padding, arm rotation can be adjusted to give a perfect view of the dis...
متن کاملComparison of free-hand fluoroscopic guidance and electromagnetic navigation in distal locking of femoral intramedullary nails
BACKGROUND Although the method has been used widely, one of the greatest challenges for intramedullary nailing is to position the distal locking screw. A new technology, the electromagnetic navigation system, is a radiation-free way to locate the position of the drill bit and provide 3-dimensional real-time feedback of location and orientation of the drill bit relative to the locking holes. The...
متن کاملIntramedullary locking femoral nails. Experience with the AO nail.
The AO interlocking nail was introduced to the Ulster Hospital, Dundonald in 1988 and since then has been used in over 50 patients with femoral shaft fractures. We have reviewed 45 patients with 46 femoral shaft fractures treated between June 1988 and April 1990. These included four compound fractures and 13 comminuted fractures. The results compare favourably with other series. The union rate ...
متن کاملIntramedullary locking nails in the management of femoral shaft fractures.
Intramedullary locking nails have proved to be of considerable advantage when treating complex, comminuted or segmental femoral shaft fractures. We have reviewed 117 patients with 120 femoral shaft fractures treated with the Strasbourg device. These included 20 compound fractures, 13 pathological fractures and two non-unions. Rehabilitation and union rates have been very satisfactory and there ...
متن کاملIntramedullary locking nails for femoral shaft fractures in elderly patients.
Fractures of the femoral shaft are generally considered to affect young patients, but we have reviewed 24 cases in patients over 60 years who have been treated by locked nailing, usually by closed methods. Most were women with low-velocity injuries, but despite this, 14 fractures were significantly comminuted. The complication rate was 54% with a peri-operative mortality of 17%. Most complicati...
