Abstract
Abstract Bones can be fused together by injecting a liquefied composition containing a non-necrotic vascular sclerosing agent into the interface region between the bones. Normally a cast or brace is not used. The preferred non-necrotic vascular sclerosing agent is sodium oleate. Splints and diffused splints can be prepared using the bone fusing technique.

Claim 5
Dependent Claim
13 words
A process as described in claim 1 wherein said liquid carrier is water.
Claim 6
Dependent Claim
48 words
A process as described in claim 1 wherein a dosage of said liquefied composition is injected into said interface region of said bones every week or two until there is a substantially complete fusion of said surfaces of said bones which are in juxaposition in said interface region.
Claim 7
Dependent Claim
24 words
A process as described in claim 1 wherein a piece of bone is fused on each end to another bone thereby creating a splint.
