The radius of curvature of femoral intramedullary nails does not match the average radius of curvature of the human femur. Anterior cortical breach of the distal femur during nail placement has been reported in certain fracture patterns, in femora with a smaller radius of curvature, and at the starting point of the nail. The authors describe a novel technique used to prevent anterior cortical d...

Intra-medullary nailing is a standard form of treatment for diaphyseal tibial fractures. Insertion of the nail requires threading of the nail over a smooth guide-wire. Inadvertent complications during this stage have been reported. We report a case of inadvertent penetration of the tibio-talar joint by the smooth guide wire caused by incarceration of a fracture fragment between the nail and the...

Closed intramedullary nailing of the femur is a complex technique but one that has considerable advantages. The choice of an appropriate point of entry into the proximal femur during introduction is vital, since an oblique insertion of the nail may lead to impaction of the implant and comminution of the proximal femoral fragment (Winquist, Hansen and Clawson 1984); this is particularly so in sm...

UNLABELLED Whether Gamma 3 fixation system is suitable for all intertrochanteric fractures is inconclusive. This paper analyzed the surgical complications of Gamma 3 intramedullary nail in the treatment of intertrochanteric fractures. METHODS A total of 186 cases were enrolled in the study including 115 males and 71 females. The surgical operations were performed in all cases and Gamma 3 intr...

This article presents new intramedullary (IM) nail design for femur diaphyseal fractures osteosynthesis. Biomechanical comparison of the two IM nails (standard locking and new developed) was conducted. Femur medullary canal architectonics was studied with the help of computer tomography (CT) data. Three-dimensional (3D) models of the femur, its transverse fracture, standard locking nail and new...

BACKGROUND There are many ways to treat aseptic non-union of femoral shaft fractures with reported varied success rate. Amongst all these, Exchange nailing is the simplest and most successful technique for treating aseptic non union of femoral shaft fractures. We have carried out a prospective study in the Department of Trauma & Orthopaedics, Ayub Medical College Abbottabad to analyse the role ...

PURPOSE Presence of a cephalomedullary nail (CMN) in the medullary canal has been thought as advantageous in the control of femoral neck shortening (FNS) and lag screw sliding in trochanteric fracture compared to extramedullary fixation system. However, researches on the factors that influence the degree of FNS after cephalomedullary nailing are lacking. MATERIALS AND METHODS We observed 95 p...

This paper describes the design of a retractable intramedullary nail for the humerus that does not require inter-locking screws. The developed nail has a series of fins which open out from the casing to grip the medullary canal of the bone, thus securing it in position. Prototypes of the nail have been mechanically tested using static compression, dynamic compression and static torsion tests. D...

We present a case report of acute spontaneous knee hemarthosis due to erosion of the nail through the knee joint capsule in a boy, seven months following retrograde flexible nailing for fractured femur. Careful positioning of the location of the insertion site of flexible nails and proper nail tip management are important to avoid this rare late complication.

background: in children, inappropriate treatment of open femoral fractures may induce several complications. a few studies have compared the external fixator with flexible intramedullary nails in high-grade open femoral fractures of children. the present study aims at comparing results of these two treatment methods in open femoral fractures. methods: in this descriptive analytical study, 27 pa...
