![]() The three dimensional spinal deformity was significantly improved and the intra-canal rib head was significantly extracted from the canal immediately after the surgery. RESULTS: Patients were followed up for at least 24 months post-operatively. Post-operative complications, surgery time and blood loss were also evaluated. The efficacy and outcomes of the surgery were evaluated by measurements before, immediately and 24 months after the surgery using the following parameters: coronal spinal Cobb angle, apex rotation and kyphosis of the spine and the intra-canal rib head position. Posterior instrumentation and spinal fusion without intra-canal rib head resection via a posterior-only approach was performed for deformity correction and rib head extraction. ![]() METHODS: Six patients with Type I neurofibromatosis scoliosis with rib head dislocation into the spinal canal were diagnosed at our institution. The purpose of this study is to share our experience in the diagnosis and surgical treatments for such unique deformities. Current knowledge regarding the diagnosis and treatment for this situation are insufficient. Posterior-only spinal fusion without rib head resection for treating type I neurofibromatosis with intra-canal rib head dislocationĭirectory of Open Access Journals (Sweden)įull Text Available OBJECTIVES: Patients with Type I neurofibromatosis scoliosis with intra-canal rib head protrusion are extremely rare. A knowledge of the factors influencing the visibility of these important injuries is useful in planning an appropriate diagnostic evaluation of suspected infant abuse Fresh rib fractures invisible on a frontal projection may be clearly defined on axial CT scans, or on postmortem radiographs. The limited visibility of fractures relates to (1) the frequent superimposition of the transverse process over the rib fracture site, (2) a fracture line that crosses at an obliquity to the x-ray beam, and (3) nondisplacement of rib fragments due to preservation of the posterior periosteum. Radiologic findings were correlated with CT findings and pathologic material from nine ribs in four patients. To assess the factors influencing the visibility of fractures near the costovertical articulations, the authors studied 103 posterior rib fractures occurring in 16 abused infants. ![]() Fractures occurring near the costovertebral articulations are usually identified radiographically only once callus has formed. Rib fractures in abused infants commonly occur in the posterior rib arcs. International Nuclear Information System (INIS) Factors affecting visualization of posterior rib fractures in abused infants
