Abstract
Abstract Disclosed is a non surgical method of modulating spinal curvature in developing vertebrates. Agents capable of temporarily interfering with neuromuscular transmission, e.g., botulinum toxin, are injected into the musculature of the back to create an imbalance in the muscular support of the developing spine. The procedure may be used to produced non human scoliosis animal models and in the clinical management of juvenile scoliosis.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
85 words
A nonsurgical method of modulating curvature of the spine during juvenile development of a vertebrate animal, the method comprising the step of: percutaneously injecting an acetylcholine transmission inhibitor, comprising an agent which mimics the effects of botulinum toxin to block muscle stimulation, into the musculature of the dorsal side of a vertebrate at a site disposed axially asymmetrically of the spine, thereby to produce alternation in the balance of muscular support of the developing spine lasting for a time sufficient to alter the curvature thereof.
Claim 2
Dependent Claim
85 words
A nonsurgical method of modulating curvature of the spine during juvenile development of a vertebrate animal, the method comprising the step of: percutaneously injecting an acetylcholine transmission inhibitor, comprising an agent which mimics the effects of botulinum toxin to block muscle stimulation, into the musculature of the dorsal side of a vertebrate at a site disposed axially asymmetrically of the spine, thereby to produce alternation in the balance of muscular support of the developing spine lasting for a time sufficient to alter the curvature thereof.
Claim 3
Dependent Claim
12 words
The method of claim 1 wherein the inhibitor is a botulinum toxin.
Claim 4
Dependent Claim
12 words
The method of claim 1 wherein the inhibitor is botulinum toxin A.
Claim 5
Dependent Claim
26 words
The method of claim 1 wherein the vertebrate animal is a non-human mammal and said injecting step results in the development of an abnormal spinal curvature.
Claim 6
Dependent Claim
35 words
The method of claim 1 wherein the vertebrate animal has an abnormal spinal curvature and said inhibitor is injected at a position in said dorsal musculature to reduce further abnormal curvature during the animal's development.
Claim 7
Dependent Claim
79 words
A non surgical method of treating abnormal juvenile developmental spinal curvature in a mammal, the method comprising the step of: percutaneously injecting an acetylcholine-release inhibitor derivative of a botulinum toxin into the musculature of the back of said mammal during its juvenile development at a site adjacent the spine to produce alteration of the balance of spinal muscular support in a direction favoring reduction of curvature and for a time sufficient to alter permanently the degree of spinal curvature.
Claim 8
Dependent Claim
79 words
A non surgical method of treating abnormal juvenile developmental spinal curvature in a mammal, the method comprising the step of: percutaneously injecting an acetylcholine-release inhibitor derivative of a botulinum toxin into the musculature of the back of said mammal during its juvenile development at a site adjacent the spine to produce alteration of the balance of spinal muscular support in a direction favoring reduction of curvature and for a time sufficient to alter permanently the degree of spinal curvature.
Claim 9
Dependent Claim
12 words
The method of claim 6 wherein said inhibitor comprises botulinum A toxin.
