What is a DHS procedure?

Dynamic hip screw x-ray [image from wikimedia] The Dynamic Hip Screw (DHS) or Sliding Hip Screw can be used as a fixation for neck of femur fractures. This would usually be considered for fractures that occur outside the hip capsule (extracapsular), often stable intertrochaneric fractures.

How does a DHS screw Work?

The DHS is based on tension band principle and allows the screw to slide within the barrel to enable compression of the fracture when the patient begins to bear weight. This principle only works in the presence of intact medial wall and so cannot be successful in a reverse oblique fracture of the proximal femur.

What is ORIF and CRIF?

Emergency internal fixation is one of the main options for the treatment of displaced femoral neck fractures [5]. It contains open reduction internal fixation (ORIF) and closed reduction internal fixation (CRIF). Both of the two methods have their advantages and disadvantages [6].

How does DHS work hip?

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.

How long is ORIF surgery?

In most cases, the surgery takes about 1 to 2 hours. But it can take longer, depending on how serious the fracture is.

How is an ORIF performed?

How Is ORIF Surgery Performed? During the surgery, your bone fragments will be repositioned into normal alignment. The bone fragments are held together with hardware such as plates, screws, or wires. The implants are made from stainless steel or titanium because these are strong and durable metals.

What is the diameter of a DHS screw?

A few points on DHS Implant and technique: Lag Screw: It has a Thread diameter – 12.5 mm, Pitch – 3 mm, Lead that is the distance travelled by screw with one turn – 18 mm. It has a Tapered thread at tip with Reverse cutting flutes for easy extraction.

What is DHS orthopedics?

Dynamic hip screws (DHS) are a femoral head-sparing orthopedic device used to treat femoral neck fractures. It is sometimes referred to as a pin and plate.

Is ORIF same as hip replacement?

ORIF utilizes open surgery to set the fracture followed by the use of plates, pins, and screws to hold the bones in place. THA involves surgically removing both the femoral head and acetabular cartilage, and replacing them with an artificial femoral head and acetabular cup.

Is ORIF an emergency surgery?

ORIF surgery is only needed for severe fractures. It’s often performed as emergency surgery. If your bone is in pieces, it may need to be repositioned and held in place with screws or plates until it heals.

How long is recovery after ORIF?

ORIF isn’t for minor fractures that can be healed with a cast or splint. ORIF recovery can last 3 to 12 months. You’ll need physical or occupational therapy, pain medication, and lots of rest. You should contact your doctor if you experience bleeding, increasing pain, or other new symptoms during recovery.
