Abstract

An anterior cervical retractor comprises a first medial-lateral retractor body having a base arm and a moving arm and a pair of retractor blades. The retractor blades may be side loading or top loading. The cervical retractor comprises a second cranial-caudal retractor body having a pair of moving arms and a pair of retractor blades. The retractor blades may have an adjustable angulation. The retractor blades may also be fixed to the spine and provide distraction upon operation of the second retractor body. The blades of the first retractor body and/or the second retractor body may be coupled to light elements that illuminate the operative corridor between the blades.
