STUDY DESIGN A retrospective study. OBJECTIVE The aim of this study was to evaluate the efficacy of laminoplasty for the treatment of patients with an occupying ratio greater than 50% and to determine possible factors related to surgical outcome of posterior decompression. SUMMARY OF BACKGROUND DATA Little data are available about effect and prognostic factors of laminoplasty for cervical m...

This study evaluated the safety of 3-level anterior cervical diskectomy and fusion (ACDF) with ultra-low-dose recombinant bone morphogenetic protein-2 (rhBMP-2). Thirty-seven consecutive patients with cervical spondylotic myelopathy who were treated with 3-level ACDF and rhBMP-2 were evaluated. Complications such as airway or cervical swelling or hematoma were not observed. The rate of dysphagi...

The aim of this stusy was to investigate whether spinal fusion to T2, T3, or T4 affects sagittal alignment of the cervical spine in Lenke 1 adolescent idiopathic scoliosis (AIS) patients.A retrospective study comprised of 64 Lenke 1 AIS patients was performed to assess the radiographic and clinical outcome. According to the upper instrumented vertebrae (UIV) (T2, T3, or T4), the patients were d...

Iniencephaly is an extremely rare neural tube defect characterized by the triad of fixed retroflexion of the head, variable degrees of cervical lordosis and dysraphism, and an occipital bone defect involving the foramen magnum. Incidence ranges from 0.1 to 10 in 10,000. Although there have been cases of iniencephaly reported as an isolated anomaly, it very rarely occurs alone. We report here a ...

What are the risks, benefits, alternatives, and pitfalls for operating on cervical ossification of the posterior longitudinal ligament (OPLL)? To successfully diagnose OPLL, it is important to obtain Magnetic Resonance Images (MR). These studies, particularly the T2 weighted images, provide the best soft-tissue documentation of cord/root compression and intrinsic cord abnormalities (e.g. edema ...

Objective: Case report of a patient, having persistent low back and leg pain following a L4-L5 surgical laminectomy, who underwent Clinical Biomechanics of Posture (CBP) protocol designed to correct postural distortions. Clinical features: A thirty-five year-old male suffered from low back/leg pain following a work injury despite having a lumbar spine laminectomy 6 months prior to chiropracti...

STUDY DESIGN Retrospective study. PURPOSE To investigate safety profile of open door laminoplasty plates. OVERVIEW OF LITERATURE Few reports have documented potential complications related to the use of cervical laminoplasty plates. METHODS Records and radiographs of consecutive plated laminoplasty patients of one academic surgeon were analyzed. Group 1 had screw back-out, defined as chan...

OBJECTIVE The anterior approach for multilevel CSM has been developed and obtained favorable outcomes. However, the operation difficulty, invasiveness and operative risks increase when multi-level involved. This study was to assess surgical parameters, complications, clinical and radiological outcomes in the treatment of 2-, 3- and 4-level CSM. METHODS A total of 248 patients with 2-, 3- or 4...
