BackgroundCervical kyphosis (CK) is an abnormal structure that accelerates cervical disc degeneration and causes neck pain. Nearly a quarter of young people have CK, yet its treatment remains controversial. Case presentation We present an interesting case of CK; In this case report, a 32-year-old male patient with neck pain was seen in our hospital, whose cervical sagittal alignment was kyphotic and was given a cervical manipulation therapy (CMT). CK was subsequently reversed into lordosis in one day after the treatment along with the patient’s clinical symptoms alleviated. Three months later, the patient complained his neck pain had come back, so we scheduled him a second X-ray. We gave him a second CMT because the radiograph showed he got CK again. A follow-up after 6 months showed that the patient’s neck pain relieved and the cervical spine was still lordotic. ConclusionsIt suggested that CK can be reversed into CL by CMT immediately, but requires continuous treatment at the early stage; neck pain may relate to CK.
