surgical management of spasticity

Stretching, splints, drugs, and injections all work on a moving target — a nerve signal that can be turned down for a while. But some problems have become permanent, or are too severe and stubborn for the gentler tools, and then surgery offers a more definitive answer. Surgical management of spasticity is the bottom rung of the treatment ladder, reached when the milder options have been tried and the goal justifies an operation.

Two broad families exist. Orthopaedic surgery works on the muscles, tendons, and bones themselves: a permanently shortened tendon can be lengthened so the joint regains range, a tight muscle can be released, an overactive muscle can be transferred to pull in a more useful direction, and a fixed deformed bone can be cut and realigned. These address the mechanical end-result — they are the answer for a true fixed contracture that no drug can touch. Neurosurgery works on the nerves: selective dorsal rhizotomy cuts the specific sensory rootlets entering the spinal cord that feed the overactive reflex, permanently reducing spasticity in the legs — most established in children with cerebral palsy and considered carefully against its irreversibility.

In rehabilitation, surgery sits at the end of the ladder for good reasons: it is irreversible, carries operative risk, and demands months of rehabilitation afterward to convert a corrected anatomy into restored function. Its honest place is for fixed contracture (orthopaedic lengthening) or severe spasticity unresponsive to everything milder (rhizotomy, or a baclofen pump as a reversible alternative). The recurring lesson of the whole field applies most sharply here: surgery changes the mechanics, but it does not restore the lost strength or control behind the upper motor neuron syndrome, and weakening a muscle that was secretly load-bearing can leave a patient worse off — so candidate selection is everything.
