Summary of background data: Lumbar interbody arthrodesis can be achieved by using autograft or allograft bone.

One of the disadvantages of using autograft bone graft is complications related to the iliac crest donor site.

Another option is using an allograft bone (ex.-femoral head from bone bank). There are few reports of using allograft bone for instrumented lumbar spinal fusion.

Methods: Fifteen patients were treated at our institution by lumbar fusion in various indications. We used allograft bone and evaluated their outcome for an average period of 3 years. The recovery rate, complications and radiographic findings were evaluated.

Results: Good radiographic and clinical results were achieved by using allograft bone graft. No complications were detected.

Conclusions: The clinical and radiographic results of Allograft bone graft, for lumbar spine arthrodesis, are impressive. One of the advantages of this method, comparing to an autograft is avoiding any donor site complications.

We present a method for the reducing a displaced radial head in children, by rotating the forearm while pressing over the displaced fragment. This has been successful in a series of 10 cases.
