Background: Various treatment modalities have been employed in the management of facial fractures, including transosseous wiring using stainless steel wire. Transosseous wires used in fixing maxillofacial fractures gradually undergo disintegration leading to the release of nickel into the blood. Aim: To investigate the serum level of nickel in patients treated with stainless steel transosseous wires. Methods: This was a prospective study carried out over a period of nine months in the Department of Oral and Maxillofacial Surgery, University of Benin Teaching Hospital, Nigeria. The study involved 101 subjects, 77 males and 24 females (male: female ratio of 3:1) who had maxillofacial fractures. The age of the subjects ranged between 10 and 70 years. Blood samples were collected at four different periods from each patient before the insertion of 0.5mm transosseous wires, at one, three and six months. Results:The results showed differences in the amounts of nickel released from transosseous wire during different periods of treatment. There was increase in nickel level in the first month (0.46 ± 0.09µg/l), reaching its highest levels in the sixth month (0.68 ± 0.06 µg/l). Conclusion: Transosseous wiring using 0.5mm stainless steel wire release measurable amount of nickel into patients' serum. The serum level of nickel in the patients in this study was comparable to the values found in healthy individuals, showing that the patients did not attain toxic serum levels for nickel within the period of study. It is however recommended that transosseous wires should not be removed within six months.
Fractures of the shaft of the tibia and fibula are common. Complications are minimal following careful application of principles during treatment by the Orthopaedic Surgeon. However, in our environment, not all patients present to the Orthopaedic Surgeon as they opt for some form of unconventional treatment, usually with the traditional bone setters. Such treatments sometimes lead to clinically unacceptable outcomes. This is a case report of a 42-year old female Nigerian with a 4-year history of post traumatic anterior angulation of the distal right tibia with severely contracted Achilles tendon following traditional bone setter’s treatment for open fractures of the distal tibia and fibula. There was 7 cm of right lower limb shortening and 45 degrees anterior angulation of a tibial malunion. She had a two- stage operation to correct the deformities. Patient achieved a plantigrade foot and fracture union without limb length discrepancy. DOI: http://dx.doi.org/10.3126/ajms.v6i1.10198 Asian Journal of Medical Sciences Vol.6(1) 2015 108-111
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
