In review of 871 lumbar fusion procedures performed during the last 8 years, the theoretical advantages of lumbar spinal instrumentation are not borne out in simple discogenic disease. Four groups of 30-35 patients without previous surgery who underwent fusion by different techniques were matched for age, sex, length of follow-up, surgeons, number of levels fused, duration of preoperative sympt...

segmental defects of the tibia are challenging therapeutic problems for both the physician and the patient. these defects may be caused by severe trauma, infection, tumors and congenital processes. several different techniques have been described for treatment of these defects including the papineau technique, allograft reconstruction, bone transport using the ilizarov frame, free vascularized ...

Two decades following their description, the significance of Modic vertebral endplate and marrow changes remains a matter of debate. These changes are closely related to the normal degenerative process affecting the lumbar spine, and their prevalence increases with age. However, the exact pathogenesis underlying these changes and their relation to segmental instability of the lumbar spine and t...

An increasing number of parturients suffering from ischaemic heart disease require anaesthetic care for labour and vaginal delivery. We present the case of a 42-year-old gravida who had previously suffered a myocardial infarction and undergone coronary artery bypass grafting. Management was directed toward prevention of haemodynamic instability by alleviation of pain and stress while minimizing...

background: segmental vitiligo is a small subset albeit persistent form of focal vitiligo with dermatomal distribution and resistant to medical therapy. in recent years, surgical therapy as hair follicle autograft transplantation has been a hot topic in management of segmental vitiligo. in this study, we evaluated the efficacy of this method in segmental vitiligo lesions. methods: the study rec...

mandibular discontinuity defects following a segmental mandibulectomy defects present a major challenge to the rehabilitation team. with no immediate intervention to rehabilitate the patient, definitive mandibular guidance prostheses with a metal guiding flange and acrylic teeth on the resected side can be used successfully to stabilize the occlusion and correct the deviation. the present case ...

Study Design: Prospective clinical study. Purpose: To determine the optimal posture for instability evaluation using flexion–extension X-ray imaging in patients with lumbar spondylolisthesis. Overview of Literature: Currently, is most practical approach instability. In imaging, achievement greatest segmental motion movement necessary. However, to our knowledge, currently, there no standardized ...

BACKGROUND Lumbar segmental rigidity (LSR) and lumbar segmental instability (LSI) are believed to be associated with low back pain (LBP), and identification of these disorders is believed to be useful for directing intervention choices. Previous studies have focussed on lumbar segmental rotation and translation, but have used widely varying methodologies. Cut-off points for the diagnosis of LSR...
