Figure 1A shows the preoperative imaging results of the patient. Left total hip replacement (March 27, Smith & Nephew); right subtrochanteric osteotomy followed by total hip replacement (April 14, Johnson & Johnson S-ROM prosthesis) (Figure 1B). Anteroposterior and lateral femur radiographs were collected for evaluation (Figure 1C). After osteotomy nonunion callus excision, bone grafting was conducted at the nonunion site; the femur was repaired with the titanium plate and screw, allogeneic bone plate reinforcing, and steel wire binding fixation (Figure 1D).
(A): anteroposterior pelvic x-ray with a diagnosis of left crowe IV DDH (left). (B): x-ray of initial subtrochanteric osteotomy with S-ROM prosthesis replacement. (C): After the patient fell, the distal end of the S-ROM prosthesis became loose, (D): x-ray of the left femur after revision of the left hip joint.

The patient was diagnosed with Crowe IV DDH (Figure 2A). The imaging exam was as depicted in Figure 2B. The left femur was injured six months ago as a result of a fall while walking; nevertheless, no special treatment was administered, and the discomfort in the affected leg steadily intensified. An x-ray was performed (Figure 2C), and the patient was admitted for surgical treatment after being diagnosed with left hip prosthesis loosening (distal femur). Titanium plates and screws were used to fix the femur, and wire was tied around the femur (Figure 2D).
(A): anteroposterior radiographs of the pelvis after the patient's initial S-ROM prosthesis replacement are shown on the left, (B): radiographs of the hip joint with loose left hip prosthesis are shown on the right one year later. (C): Anterior and lateral femur radiation after revision of the femur.

After revision, the review was conducted at 3, 6, and 12 months postoperatively. that the hip implant loosening healed effectively (Figure 4).
