Monteggia fractures are uncommon and frequently missed injuries in children. This article aims to study, in a systematic manner, the surgical management and complications of treatment of chronic radial head dislocations. After screening of relevant abstracts, a total of 28 studies were included in the systematic review. A narrative synthesis of various treatment modalities has been discussed. This article concludes that open reduction should be attempted unless dysmorphism of the radial head restricts it. Open reduction with ulnar osteotomy with or without annular ligament reconstruction is the most commonly performed procedure and is expected to result in reduced pain and elbow deformity.

Early anatomical reduction and surgical fixation remains the best option to reduce the risk of complications like non-union and avascular necrosis in treating fracture neck femurs. Cancellous screws continue to be the preferred treatment for fixation of neck femur fractures in younger population until the benefit of using sliding hip screws is validated by large multicentric studies. In the geriatric age group, early prosthetic replacement brings down the mortality and morbidity associated with neck femur fractures. Sliding hip screw (DHS) is the best available option for stable inter trochanteric fractures. The use of intramedullary nails e.g. PFN is beneficial in treating inter trochanteric fractures with comminution and loss of lateral buttress. Intramedullary implants have been proven to have increased success rates in subtrochanteric fractures and should be preferred over extramedullary plate fixation systems.

An ordered hexagonal mesoporous nickel oxide was prepared for the first time using sodium dodecyl sulfate as the surfactant and urea as the hydrolyzing agent. The resulting oxide showed mesoporous structure with pore size ranging from 4 to 7 nm. Calcination at different temperatures was carried out, and the mesoporosity did not collapse even after calcination at 773 K although the surface area decreased drastically (from 279 to 72 m 2 /g) and a broader pore size distribution was observed.
