![]() Because component failure may have a protracted subclinical course, detecting any findings of malfunction relies heavily on routine radiographic assessment these findings may be subtle, so a high index of suspicion is crucial. Detecting complications after arthroplasty is the result of thorough clinical investigation, history taking, examination, and judicious use of supportive radiologic and laboratory studies. Given sufficient time, all prostheses eventually fail. The specific type of prosthesis, surgical technique, and surgeon-related and patient-related factors play a role in the relative frequency with which complications occur. ![]() Although the types of prostheses continuously evolve, hip prostheses may be divided simply into unipolar, bipolar, and total arthroplasties, with the last divided further by bearing surface (metal on polyethylene, metal on metal, ceramic on ceramic, and ceramic on polyethylene). The high prevalence of hip pathology and the broad success of hip replacement surgery have resulted in hip arthroplasty becoming a routine procedure, with an estimated 170,000 primary hip arthroplasties performed annually in the United States and approximately 35,000 revision surgeries performed as revision surgery. More sophisticated imaging and image-guided interventions may then be used to determine the cause of failure, primarily to exclude sepsis. In a postarthroplasty patient, subtle changes may often be indicators of loosening and hardware failure. The relative ease of radiographic comparison allows for more accurate monitoring of disease progression. Cross-sectional imaging may be used for disease confirmation and determination of severity and extent. Together with the clinical evaluation and laboratory studies, radiographic evaluation serves as the first line of investigation of any hip pain, providing an overall view of the hip joint. Most patients take about 4-6 weeks to walk without any assistance and to engage in their normal activities of daily living.Radiographic evaluation of the hip before and after arthroplasty is the cornerstone of radiologic assessment. You will also be given a daily exercise program that will help speed up your recovery. A physical therapist will provide instructions to help you with sitting or standing on the same day of surgery. Postoperative Care and Instructions for X-ray Guided Hip ReplacementĪfter the surgery, you will be moved to the recovery room where you will be under observation for a few hours. The implant is then fixed, the range of motion of the joint is tested, and the incision is closed with sutures.Special surgical instruments are introduced into the hip and based on the anatomic landmarks identified on the X-rays, the damaged tissue is removed and your surgeon will make precise cuts in your bone to place the implant components in the desired position.A small incision will be made on the side or back of the hip.The procedure can be performed under general or spinal anesthesia.Procedure for X-ray Guided Hip Replacement The X-rays help in the selection and sizing of the implants based on your anatomy and can be used to identify anatomical landmarks that serve as reference points so that the prosthesis is implanted in the correct position.Multiple X-rays will be taken to measure the length and depth of the damaged joint.Your doctor will review your medical history and symptoms and based on this a physical examination of the hip will be performed.Pre-operative preparation for x-ray guided hip replacement includes: Preparation for X-ray Guided Hip Replacement The bones are held together by several bands of tissue called ligaments which provide stability to the joint. The bone surfaces in the joint are covered by smooth articular cartilage that enables smooth movement of the joint. The hip joint is a weight-bearing, ball-and-socket joint in which the head of the femur forms the ball, and the pelvic acetabulum forms the socket. Helps the surgeon anticipate potential difficulties with the surgery.Benefits of X-ray Guided Hip Replacementīenefits of X-ray guided hip replacement include: X-ray guided hip replacement involves the use of pre-operative radiographic studies to help select the right size of the implant and to determine the proper position in which the implant should be placed. Hip replacement is a surgical procedure in which the damaged hip joint is replaced with a prosthetic implant. X-ray Guided Hip Replacement What is X-ray Guided Hip Replacement?
