How does a dynamic hip screw work?

A dynamic hip screw is performed where the neck of femur has been fractured and where there is a good chance that it will heal if held in place by internal fixation. The internal metal work consists of a large screw placed in the head of the femur and a plate held onto the side of the femur by several smaller screws.

What is a sliding screw?

The Dynamic Hip Screw (DHS) or Sliding Hip Screw can be used as a fixation for neck of femur fractures. This is because there is a reduced chance of interruption to the blood supply to the head of the femur, and so it may be possible to preserve the joint.

Can you weight bear after dynamic hip screw?

In the aftercare, specially in fractures that have been stabilised with a DHS, partial weight-bearing is recommended. Some other authors describe immediate full weight-bearing after osteosynthesis with the same implant. For elderly patients it is often difficult to apply partial weight-bearing on one limb only.

Does a dynamic hip screw need to be removed?

A dynamic hip screw is performed where the neck of femur has been fractured and where there is a good chance that it will heal if held in place by internal fixation. What are the benefits? No bone needs to be replaced or removed; therefore patients can be fully weight bearing on the operated limb day 1 post op.

Why it is called dynamic hip screw?

Dynamic hip screw (DHS) or Sliding Screw Fixation is a type of orthopaedic implant designed for fixation of certain types of hip fractures which allows controlled dynamic sliding of the femoral head component along the construct.

Is a dynamic hip screw and intramedullary nail?

Dynamic Hip Screw fixation is currently considered as a standard treatment for pre-trochanteric fractures; however, due to the long-term hospitalization and some other complications, some researchers have proposed intramedullary nailing as the alternative surgical treatment.

Is a dynamic hip screw an intramedullary nail?

Introduction: Dynamic Hip Screw fixation is currently considered as a standard treatment for pre-trochanteric fractures; however, due to the long-term hospitalization and some other complications, some researchers have proposed intramedullary nailing as the alternative surgical treatment.

How does a sliding hip screw work on the femoral head?

Push it through the hip capsule, slide it along the neck, and gently tap it into the femoral head. The guide wire demonstrates both femoral neck anteversion and neck-shaft angle, thus confirming appropriate sliding hip screw angle and definitive guide wire anteversion. Choose the correct aiming device according to the CCD angle of the neck.

How are hip screws used in hip surgery?

In this operation, a screw is passed into ball of the hip and a plate is passed over it and fixed to the thigh bone (see figure 2). The plate is secured with screws. This type of repair will allow you to start walking early, reducing the need for you to be bed bound. Dynamic hip screw (sliding hip screw) Trauma and Orthopaedics

What do you mean by dynamic hip screw?

Dynamic hip screw. Jump to navigation Jump to search. Dynamic hip screw. Dynamic hip screw (DHS) or Sliding Screw Fixation is a type of orthopaedic implant designed for fixation of certain types of hip fractures which allows controlled dynamic sliding of the femoral head component along the construct.

When to use a tap for a sliding hip screw?

In young patients with hard bone, it is best to use the tap to precut the thread for the screw. Otherwise the screw may not advance, and you may actually displace the fracture by twisting the proximal fragment as you attempt to insert the screw.
