Evaluation of Locked Plate in the Osteosynthesis of Fractures in Osteoporotic Bones

BACKGROUND: The use of conventional dynamic compression plates (DCPs) in osteoporotic bones is associated with higher chances of implant failure. The advent and use of locking combi-plates have ensured a stable construct during osteosynthesis of fractures in osteoporotic bones. OBJECTIVES: The study aims to assess the outcome of use of locking combi-plates in the management of fractures in osteoporotic bones in our environment. MATERIALS AND METHODS: Cases of patients with nonunion and localized osteoporosis from January 2014 to December 2014 that were managed with locked combi-plates were reviewed. Outcome was assessed by time to healing, stability of implant construct after 6 and 12 months. RESULTS: There were 10 patients with mean age of 47.4 ± 12.63 years. There were 9 males and 1 female, and road traffic crashes were the mechanism of injury in 90% (n = 9) and gunshot injuries in 10% (n = 1). Atrophic nonunion was the most common indication for osteosynthesis with 80%, followed by fibrous nonunion with 10.0%. The humerus was the most common long bone involved with 50%. Locked broad DCP was used in 62.5%, and the duration between initial injury and surgery was 6 and 48 months, with an average of 17.5 months. The outcome was such that 90% healed after 12 months on follow-up while one case had the implant backing out and delay union at 6 months. CONCLUSION: The use of locked plate in the management of nonunion in the presence of osteoporosis ensures stable fixation construct and healing.
