What are the modalities of fixation of intertrochanteric fracture?
Various treatment modalities have been introduced to date for the reduction of intertrochanteric fractures, including DHS, proximal femoral nail, bipolar hemiarthroplasty, trochanteric fixation nail (TNF) and external fixation, all of which have their specific advantages and disadvantages (8,9).
What is intramedullary implant?
An intramedullary rod, also known as an intramedullary nail (IM nail) or inter-locking nail or Küntscher nail (without proximal or distal fixation), is a metal rod forced into the medullary cavity of a bone. IM nails have long been used to treat fractures of long bones of the body.
What is intramedullary fixation devices?
Intramedullary fixation devices (IMFDs), such as nails and rods, are used for the fixation of various bones and are typically used in the femur, tibia, humerus, radius and ulna. An IMFD subjected to cyclical loading can fail due to fatigue if stresses on the device exceed its endurance limit.
What is the treatment of an intertrochanteric hip fracture?
Intertrochanteric fractures are treated surgically with either a sliding compression hip screw and side plate or an intramedullary nail. The compression hip screw is fixed to the outer side of the bone with bone screws. A large secondary screw (lag screw) is placed through the plate into the femoral head and neck.
What type of fracture is intertrochanteric?
An intertrochanteric fracture is a type of hip fracture or broken hip. The hip is made up of two bones—the femur, or “thigh bone,” and the pelvis, or “socket.” The hip is an important ball-in-socket joint that allows you to move your leg when walking.
What is an intramedullary fracture?
Intramedullary (IM) fracture fixation serves to stabilize fracture fragments and maintains alignment, while permitting motion at the fracture site during functional activities.
What is extramedullary fixation?
Extramedullary fixation of hip fractures involves the application of a plate and screws to the lateral side of the proximal femur. In external fixators, the stabilising component is held outside the thigh by pins or screws driven into the bone.
What is fracture fixation?
Abstract. The basic goal of fracture fixation is to stabilize the fractured bone, to enable fast healing of the injured bone, and to return early mobility and full function of the injured extremity. Fractures can be treated conservatively or with external and internal fixation.
What is Orthopaedic fixation?
Orthopedic fixation devices are used in the treatment of fractures, soft-tissue injuries, and reconstructive surgery. After fracture reduction, internal, external, or intramedullary fixation devices may be used to provide stability and maintain the alignment of bone fragments during the healing process.
What is the role of a hip arthroplasty in intertrochanteric fractures?
Hip arthroplasty is an alternative in older patients with intertrochanteric femur fractures at high risk of fixation failure or with concomitant intraarticular pathologies.
Are sliding hip screws and side plates effective for intertrochanteric fractures?
The sliding hip screw and side plate have for decades been the implant of choice in the management of intertrochanteric (IT) hip fractures . Several studies have shown the satisfactory results achieved with the use of this implant design [2, 3].
What is the treatment for intertrochanteric femur fractures?
Intertrochanteric femur fractures are common in older patients and often have a significant impact on disability. The treatment aims to achieve a rapid return to the prior functional level with a low rate of complications and mortality. Surgical management by internal fixation is the mainstay of treatment for most of these fractures.
When is intramedullary nailing indicated in the treatment of intertrochanteric fractures?
Intramedullary nailing of an unstable intertrochanteric fracture with the Gamma nail, preoperatively, 1 month and 6 months after surgery Open in a separate window
