Understanding Dynamic Hip Screw (DHS) Surgery
Dynamic Hip Screw (DHS) Fixation is a surgical procedure used to treat specific types of hip fractures, particularly in older adults. The surgery involves inserting a large screw into the head of the femur (thigh bone) and attaching a side plate to the femoral shaft to stabilize the fracture. This method allows controlled movement of the femoral head, promoting healing and reducing complications.
Procedure Details of DHS Fixation
The DHS procedure begins with a small incision near the hip, through which the surgeon accesses the fractured femur. Using fluoroscopic imaging, a lag screw is precisely inserted into the femoral head, and a side plate is secured along the femoral shaft with multiple screws. This setup permits controlled sliding of the femoral head, facilitating compression at the fracture site, which is essential for healing. The design of the DHS allows for dynamic compression, enabling the bone to heal under the natural stress of weight-bearing activities. This technique is particularly beneficial for patients with osteoporotic bone, as it provides stability and promotes bone healing.
Medical Reasons for DHS Surgery
- To stabilize intertrochanteric and certain femoral neck fractures.
- To allow early weight-bearing and movement after hip fractures.
- To reduce pain caused by unstable fractures.
- To prevent complications such as bone misalignment or delayed healing.
Instruments and Implants Used in DHS Surgery

Benefits of Choosing DHS Surgery
- Promotes stable fracture healing with controlled compression.
- Enables early mobilization, reducing risk of complications from immobility.
- Minimally invasive compared to other fixation methods.
- Provides strong mechanical support for weight-bearing.
- Reduces hospital stay and improves functional recovery.
