Background:It has been observed that the correction of severe posttuberculous angular kyphosis is still a challenge, mainly because of the neurologic risk.Methods:Nine patients were reviewed after surgery (mean follow-up 18 months). There were 2 thoracic, 4 thoraco-lumbar and 3 lumbar kyphosis. The mean age at surgery was 23.Clinical results were evaluated by the Oswestry Disability Index (ODI) and by the neurologic evaluation. Preoperative, postoperative and final follow-up X-rays were assessed.The surgery included a posterior approach with cord release and correction by transpedicular wedge osteotomy and widening of the spinal canal.Results:Average kyphotic angulation was 72° before surgery, 10° after surgery and 12° at follow-up. Three out of four patients with neural deficit showed improvement. Neurologic complications included a transitory quadriceps paralysis, likely by foraminal compression of the root.Conclusion:A posterior transpedicular wedge osteotomy allows a substantial correction of the kyphosis, more by deflexion than by elongation, with limited neurologic risks. However it is mandatory to widely enlarge the spinal canal on the levels adjacent to the osteotomy, in order to allow the dura to expand backwards.

The objective of this study was to determine the influence of branch type on the cutting ability of eight kola clones (Cola nitida). To this end, the clones were tested in a split-plot experimental design with the factors studied being the clone and the nature of the branch. After seven weeks of experimentation, survival rates were evaluated for each clone and for each type of cutting. The results showed that the clones were significantly different for the survival rates obtained (p = 0.00). The terminal branches were more suitable for cutting (70.62% survival) than the sub-terminal branches (33.95%). The age of cutting therefore influenced the success of cutting in the clones studied. At the end this work, we note that clones 305, 323, 330, 903A3 and 911A2 are promising for kola tree cutting from terminal branch and that clone 910A1 cut easily with both terminal and sub-terminal branch.

Symptomatic accessory navicular bone is a rare condition. The authors report the case of a 30-year-old nurse who had chronic pain in the medial face of her right foot that was resisting to medical treatment. The Radiography revealed the presence of a large accessory navicular bone. Since the treatment was inefficacy, though well conducted, a surgical treatment was administered to the patient which allowed the complete regression of her symptoms. In this case, we will report the diagnostic elements and the different surgical modalities.
