Treatment of the Dislocated Hip in Infants With Spasticity

Spontaneous non-traumatic hip dislocation in patients with stroke

This is a unique clinical case of a spontaneous non-traumatic hip dislocation in a patient with stroke with a hip and knee flexion pattern. This case highlights the role of spasticity as a cause of hip dislocation and the need to combine focal spasticity treatment and surgery to restore ambulation.

Orthopedic treatment of the lower limbs in spastic paralysis

Spastic paralysis of the limb mainly results from the central lesion, in which spastic cerebral palsy is the common cause. Due to durative muscle spasm in spastic cerebral palsy, it is often accompanied by the formation of secondary musculoskeletal deformities, resulting in limb motor disability. Based on its pathogenesis, surgical treatment is currently applied: selective posterior rhizotomy (SPR) or orthopedic surgery. The primary purpose of early orthopedic surgery was simply to correct limb deformities, which usually led to the recurrence of deformity as a result of the presence of spasticity. With the application of SPR, high muscle tone was successfully relieved, but limb deformity was still present postoperatively. Therefore, this study aimed to elaborate on the management of orthopedic surgery, common deformities of the lower limb, and orthopedic operative methods; discuss the relationship between SPR and orthopedic procedure for limb deformity; and focus on the indications, timing of intervention, and postoperative outcome of different surgical methods.
