Screw and Sheath System for Fixation of Fractures or Osteotomies

Intended to be used forfixation of tissue, including ligament or tendon to bone, or a bone/tendon to bone.Interference fixation is appropriate for surgeries of the knee, shoulder, elbow, ankle, foot, and hand/wrist where the sizes offered are patient appropriate.

The screw and sheath system is commonly used in orthopedic surgery for various applications, such as fixation of bone fractures or ligament repairs. Here is a general overview of the operation of the screw and sheath system:Pre-operative planning: The surgeon will assess the patient's condition, review medical imaging (such as X-rays or MRI scans), and determine the appropriate size and type of screws and sheaths required for the procedure.Incision and exposure: The surgeon will make an incision at the surgical site to access the affected area. Soft tissues, muscles, and other structures are carefully moved aside or retracted to expose the bone or ligament that requires repair.Drilling pilot holes: Using specialized surgical drills, the surgeon will carefully create pilot holes in the bone to accommodate the screws. These pilot holes ensure proper placement and stability of the screws.Inserting the sheath: The sheath is a hollow tube-like structure that is inserted into the pilot hole. It acts as a guide, protecting the surrounding soft tissues and allowing precise placement of the screw.Screw placement: The screw, typically made of titanium or stainless steel, is inserted through the sheath and into the pilot hole. The screw is threaded and can be tightened to fixate the bone or connect two pieces of bone together.Securing the screw: Once the screw is fully inserted, the surgeon may use a screwdriver or other appropriate tools to secure the screw in its final position. This may involve tightening the screw to achieve the desired compression or stabilization.Closure: Once the screw and sheath are properly placed and secured, the surgeon will close the incision using sutures or staples. The wound is then cleaned and dressed.It's important to note that the screw and sheath system's operation can vary depending on the specific procedure and the anatomical location involved. The surgeon's expertise and experience are essential in ensuring accurate placement and optimal results.
