STUDY DESIGN A study to analyze the changes of the spinal deformity during the growth period, with regard to different operations for spinal tuberculosis in children. OBJECTIVES To quantify the changes in the kyphotic angle and the growth ratio of the fusion bloc during spinal growth for different fusion techniques. SUMMARY OF BACKGROUND DATA Most of(More)
Gluteal compartment syndrome is uncommon and is often diagnosed late, resulting in muscle necrosis and sciatic nerve palsy. The mainstay of treatment is prompt diagnosis and early surgery. A high index of suspicion is essential, especially in the setting of major bleeding and excessive pain. Embolization and hyperbaric oxygen may be considered as adjuncts(More)
Venous flow-through flaps (venous flaps) are useful reconstructive options, particularly in the repair of defects with segmental vessel loss. They are relatively easy to harvest and confer several benefits at the donor site. However, given that they are based on a single central vein, their survival is notoriously unreliable and they are susceptible to(More)
BACKGROUND Management of soft tissue injuries of the heel is challenging and the composition of free tissue transfer that provides optimal aesthetic and functional outcomes in heel reconstruction is not clear. While fasciocutaneous flaps may result in shear planes that cause instability with mobilization, insensate muscle flaps may not be able to withstand(More)
Large scalp defects can require complicated options for reconstruction, often only achieved with free flaps. In some cases, even a single free flap may not suffice. We review the literature for options in the coverage of all reported large scalp defects, and report a unique case in which total scalp reconstruction was required. In this case, two(More)
Posterior lumbar vertebral apophyseal ring fractures are described in three adolescents presenting with severe low back pain, spinal tenderness and lower limb neurological deficit. Magnetic resonance imaging showed severe L4/5 posterior disc protrusion in all three patients. The actual fracture fragment was visualized with difficulty on MRI alone. The(More)
sagittal split osteotomies of the mandible, and genioplasty. There had been concern that mandibular bone generated following distraction would not provide the skeletal architecture (i.e., bicortical bone with an intervening marrow space) that is critical for the success of a sagittal split of the ramus and body of the mandible. However, we found that the(More)
BACKGROUND Ameloblastoma is a locally aggressive odontogenic tumour of the mandible and maxilla that, if neglected, can cause severe facial disfigurement and functional impairment. A thorough understanding of its clinicopathological behaviour is essential to avoid recurrence associated with inadequately treated disease. Currently, wide resection and(More)
