BACKGROUND There is considerable controversy about the long-term morbidity associated with the use of posterior autologous iliac crest bone graft for lumbar spine fusion procedures compared with the use of bone-graft substitutes. The hypothesis of this study was that there is no long-term difference in outcome for patients who had posterior lumbar fusion with or without iliac crest autograft. ...

STUDY DESIGN Retrospective review of radiographs and charts (case-only). OBJECTIVE The aim of this study was to describe the long-term outcomes of spine fusion for neuromuscular scoliosis in children below 10 years of age with cerebral palsy (CP). SUMMARY OF BACKGROUND DATA Severely involved children with CP may develop early-onset scoliosis. The outcome of spine fusion is not clear and the...

Although laminar screw fixation is often used at the C2 and C7 levels, only few previous case reports have presented the use of laminar screws at the C3-C6 levels. Here, we report a novel fixation method involving the use of practical laminar screws in the subaxial spine. We used laminar screws in the subaxial cervical spine in two cases to prevent vertebral artery injury and in one case to min...

STUDY DESIGN Retrospective cohort study. OBJECTIVE To examine the risk of undergoing another cervical spine surgery after single-level posterior cervical foraminotomy (PCF) and analyze the costs of such reoperations. METHODS Using the PearlDiver database, we created database algorithms to identify cohorts of patients who underwent single-level PCF and also had various reoperations of intere...

Recently, numerous types of posterior dynamic stabilization (PDS) devices have been introduced as an alternative to the fusion devices for the surgical treatment of degenerative lumbar spine. It is hypothesized that the use of ‘compliant’ materials such as Nitinol (Ni–Ti alloy, elastic modulus = 75 GPa) or polyether-etherketone (PEEK, elastic modulus = 3.2 GPa) in PDS can restore stability of t...

The standard surgical management of AIS is spinal fusion. Nonfusion solutions for addressing moderate AIS curves are desirable. ApiFix® is a new posterior dynamic device consisting of an expandable ratcheting rod anchored by two pedicle screws to the concave side of the scoliotic spine. It was designed to address single, moderate Lenke type 1 or 5 curves. Surgery is performed without the additi...

Posterior spinal instrumentation and fusion techniques are used over decades to correct spinal deformities higher than 40 degrees in scoliotic subjects [1]. Although these methods are successfully decreased the spinal curvature in scoliosis, the biomechanical loading of the distal unfused vertebrae is not well studied after operation. Among unfused vertebrae sacrum, the connective vertebra betw...

Study Design Prospective clinical study. Purpose The purpose of this study was to evaluate the effect of interlaminar fusion and short segment pedicle screw fixation on thoracolumbar vertebral injuries for preventing pain and post-traumatic kyphosis. Overview of Literature The treatment of thoracolumbar injuries continues to be one of the most controversial areas in spine care. The main aim...

INTRODUCTION The diagnosis of cervical spine injuries remains a significant problem in many blunt trauma patients. Correct and early diagnosis of these injuries is imperative as delayed or missed diagnoses result in increased morbidity and mortality. CASE PRESENTATION A 57-year-old Caucasian woman presented with a misdiagnosed bilateral C5-C6 dislocation one month after a fall and head injury...
