Summary

This observational study aims to learn about the outcomes in the previously operated patient and whether pelvic bone rearrangement surgery was a success. The main question it aims to answer is: • Should the investigators perform pelvic rearrangement surgery on a patient if there's not enough bone stock to accomplish the exchange of the components? As the research started the participant was asked to attend outpatient clinics regularly and keep in touch. The investigators were able to observe the outcomes and closely explore probable risks for failure.

Detailed description

A 56-year-old female patient had a hip operation one year previously and experienced her first dislocation two months postoperatively. The patient underwent closed reduction three times. The patient presented to us due to a fourth hip dislocation that had occurred one month previously. Hip X-ray images revealed acetabular component malposition, with an 80-degree inclination and 20 degrees of cup anteversion with a posterior hip dislocation. The investigators treated the patient via pelvic osteotomy, using a modified Stoppa approach to reduce acetabular inclination. The patient had no dislocation at the 2-year follow-up. At the last follow-up, the Harris Hip Score was 85.

Conditions

• Congenital Hip Dysplasia
• Hip Osteoarthritis

Interventions

Type	Name	Description
PROCEDURE	Pelvic Osteotomy - Ganz Procedure	Ischial osteotomy was performed on the pubic arch; this was followed by iliac osteotomy, performed using Schanz screws in the iliac wing. The osteotomized acetabulum was overturned, and inclination was reduced.
