What are the complications after femoral head replacement surgery

Hemiarthroplasty is a common surgery. For friends who are about to undergo hemiarthroplasty, it may be helpful to learn about the complications after hemiarthroplasty. So what are the complications after hemiarthroplasty? Next, this article will introduce you to the relevant content of complications after femoral head replacement surgery for your reference only. Friends who want to know what complications there are after hip replacement surgery can take a look.

What are the complications after hip replacement surgery? Complications after hip replacement surgery include:

1. Hip dislocation

The causes were large range of external rotator muscle injury, small femoral head, loose joint capsule suture, premature and large hip flexion, etc.; the cause of one dislocation in this group was the patient's extreme lack of cooperation after surgery and large hip flexion. After the dislocation, supracondylar traction was performed and then reduced, and traction was maintained for one month before the patient got out of bed and walked.

2. Pain

One common cause of pain is that the neck of the artificial femoral head is too long, causing the gap between the femoral head and the acetabulum to become relatively narrow, resulting in pain when walking and bearing weight after surgery. Another reason is that the artificial femoral head is too large, causing abnormal friction between the acetabulum and the femoral head and causing pain. To prevent pain after artificial femoral head replacement, you should strictly follow the surgical indications, choose a suitable prosthesis, and follow the operating standards. If pain occurs, you should receive timely and appropriate treatment. If the effect is not good, you can replace the head again.

3. Osteoporosis: The main reason for prosthesis loosening is osteoporosis caused by long-term bed rest, which in turn causes prosthesis loosening and sinking after loosening; if the condition is obvious, revision surgery may be considered; the key to preventing osteoporosis and prosthesis loosening is to avoid long-term bed rest and early activities after surgery.

4. Heterotopic ossification around joints

Heterotopic ossification around the joint is related to the failure to clean up the residual bone debris around the joint during surgery, excessive dissection range, and blood accumulation in the incision. To prevent heterotopic ossification around the joint, excessive separation should be avoided as much as possible during the operation, bone debris in the joint cavity should be thoroughly flushed with normal saline, and a negative pressure drainage tube should be placed to prevent blood accumulation in the incision.

5. Subsidence of artificial femoral head

Artificial femoral head subsidence is a common complication. Excessive resection of the femoral neck during surgery is the main cause of subsidence. Because the femoral neck is a hard cortical bone, it is an important structure to prevent the artificial femoral head from sinking. Other reasons include osteoporosis at the upper end of the femur and bone absorption on the inner side of the femur where the prosthesis contacts. The key to preventing sinking is to keep the femoral neck section at least 1.0 cm away from the lesser trochanter during surgery. If the patient has obvious osteoporosis, it is best to add bone cement to increase firmness and avoid sinking.

The above is an introduction to the complications after hip replacement surgery. From the above introduction, we can see that there are many complications after femoral head replacement. However, don't worry too much. In fact, as long as the operation is done well, such complications rarely occur.
