Wrist treatment in spastic cerebral palsy includes splints, botulinum toxin, tendon transfers, tendon lengthening, capsular liberations, and arthrodesis. A well-indicated wrist arthrodesis corrects deformity improving function and cosmetic appearance in patients with fixed deformities. It is indicated in patients with cerebral palsy, older than 12 years with a fixed deformity in wrist flexion. We report 11 clinical cases with the wrist arthrodesis with a plate of 3.5 with 2.7 mm by dorsal approach and technical resources to minimize the complications of tendon irritation and dorsal discomfort. We present an illustrative clinical case. It is a known procedure, its execution must be careful to avoid complications.
