Purpose:The purpose of this study is to investigate the constant necessity of distal locking when intertrochanteric fracture was treated with an intramedullary hip nail. Materials and Methods: From April 2010 to June 2013, 47 stable intertrochanteric fractures (AO/OTA 31-A1) were treated with second generation intramedullary hip nailing. They were followed-up for more than 12 months. In the first group of 18 cases distal locking was used, and in the second group of 29 cases, distal locking was not used. We compared the radiologic and clinical results of the two groups. Results: Comparison of the two groups of patients showed no difference in terms of radiological and functional results. Postoperative thigh pain developed in eight cases (17%). A statistically difference was observed between isthmic diameter and used nail diameter (Fisher exact test, p=0.01) for postoperative thigh pain. In logistic regression analysis, the difference between isthmic diameter and used nail diameter was the most statistically significant factor in development of postoperative thigh pain (p=0.04, odd ratio=27.75). Conclusion: Our results suggested that the second generation intramedullary hip nail may be successfully implanted without distal interlocking in 31-A1 intertrochanteric femur fracture when the reduction status was satisfactory and stable fixation of the distal area was estimated by less than 3 mm difference between isthmic diameter and used nail diameter.
Myopericytoma is a rare, usually benign soft tissue tumour that arises most commonly in the dermis and subcutaneous soft tissue of the lower extremities. In this article, we present an unusual case of myopericytoma occurring in the deep soft tissue around the knee that mimicked a neurogenic tumour. Myopericytoma can be confused with neurogenic tumour when located in deep soft tissue and adjacent to nerve bundles. Preoperative MRI and colour Doppler ultrasound may help differentiate myopericytoma from neurogenic tumour by revealing the hypervascular nature of the tumour.
Postaxial polydactyly of the foot is one of the most common congenital malformations. Only a few cases of postaxial polydactyly with a partial duplication of the fifth metatarsal without a supernumerary digit have been reported, and both metatarsal heads were united to form a common joint with the proximal phalanx in all of those cases. We present a rare case of postaxial polydactyly with a partial duplication of the fifth metatarsal characterized by dual metatarsal heads and an extra proximal phalanx bud, without a supernumerary digit.
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.
