Abstract
Study Design Case report.
Objective Amyoplasia-type arthrogryposis is a rare congenital disease that presents as multiple
contractures involving various areas of the body. To the authors' knowledge, there
have been no reports of adults with amyoplasia in the current literature. We report
a case of an adult patient with cervical stenosis in the setting of amyoplasia.
Patients and Methods A 48-year-old patient with amyoplasia and over 30 previous orthopedic reconstructive
surgeries presented with neck pain radiating down his left shoulder and into the fingers,
dysesthesia in his fingertips, and left-sided periauricular headache. A diagnosis
of central spinal canal stenosis and bilateral foraminal stenosis at C3–C7 with radiculopathy
was made based on computed tomography scans. Because of a prior right-side sternocleidomastoid
muscle transfer, a left-side C3–C4, C5–C7 anterior cervical discectomy and fusion
procedure was performed.
Results The patient experienced significant improvement in symptoms that was transient. Symptoms
returned to preoperative values after 1 year, despite significant and persistent improvement
in stenosis.
Conclusions Both amyoplasia and cervical stenosis can manifest in neurologic symptoms. Distinguishing
the causing pathology can be challenging. The radiographic improvement of cervical
stenosis in a patient with amyoplasia is not always associated with long-standing
pain relief.
