Bone transportation technology (Ilizarov technique) effectively solves the clinical problem of chronic osteomyelitis with structural bone defect. The paper combined with own clinical experience and a large number of literatures, the results showed that this method had some complications related to severe bone healing, such as non union of the joint ends and poor mineralization of the extended gap. Maintenance of force line during operation, protection of osteotomy end tissues, appropriate transporting velocity and stress stimulation after operation, and application of "accordion technology" are the keys to reduce such complications. At present, there is still much controversy about the timing of removal of external fixator. Once the re fracture is caused by early removal, it must be treated actively as soon as possible. In addition, it is necessary to reduce the local thermal injury of nail canal during operation and strengthen the nursing of nail canal after operation in order to prevent nail canal infection. Reasonable analgesic regimen combined with active functional exercise is an important method to avoid the occurrence of adjacent joint dysfunction.

Background: Length unstable femoral shaft fractures in school-aged children usually demand surgical treatment, but the optimal choice remains controversial, especially in overweight adolescents. This study aimed to compare the clinical results of locking compression plates (LCP) and elastic stable intramedullary nails (ESIN) combined with temporary external fixator (TEF) in school-aged children weighing over 50 kg.
Methods: Between January 2010 and January 2018, children over 50 kg with length unstable femoral shaft fracture treated with ESIN & EF in the authors' institute were included in this study.

Introduction Endodontic re-infections primarily occur due to the ingress of bacteria and their toxins through an incomplete seal following obturation. A variety of sealers have been developed to achieve effective integration with the different obturation materials and dentinal tubules. To choose the right endodontic sealer and application for each clinical instance, one must be aware of the attributes of the various sealers commonly used in clinical practice.

Subtrochanteric femoral fractures are one of the common fractures encountered in today's Orthopaedic practice. This area consists of mostly cortical bone with high stress generation thus heal slowly which leads implant failure. The inherent instability of this fracture and forces of the muscles with comminuted medial calcar is giving the fracture a tendency to varus collapse.

Objective: To study the morphology of canine and feline femurs and tibias in lateral radiographic projections and assess their compatibility with either a straight or a curved full-length interlocking nail (ILN).
Methods: Lateral projection radiographs of 50 tibias and 50 femurs (10 cats and 40 dogs per bone) were used to measure the minimum and maximum radius of curvature of an ILN compatible with each bone. These radii were defined by cranial and caudal endosteal points at the proximal entry point of the nail, at the isthmus, and at the most distal point of the ILN insertion into the femoral or tibial metaphysis.

A 57-year-old man presented with a tibial shaft fracture treated with tibial intramedullary nail fixation and plate and screw fixation for fibular fracture. Two weeks postoperatively, the patient developed skin sloughing with exposed bone and metal at the fracture site. Three weeks postoperatively, a physical examination revealed swelling of the left lateral malleolus and lower leg, a skin defect of approximately 3 × 5 cm at the lower third of the left tibia with an exposed fracture site and hardware in between the fracture fragments.
