Socket wall addition for dislocating total hip. Report of two cases

Area of Science:

• Orthopedic Surgery
• Arthroplasty
• Biomedical Engineering

Background:

• Recurrent dislocation is a significant complication following total hip arthroplasty, particularly in revised cases.
• Revision total hip arthroplasty presents unique challenges, including compromised bone stock and altered biomechanics.
• Addressing instability often requires complex reconstructive techniques.

Observation:

• Two patients with recurrent dislocation after revised total hip prosthesis were treated with socket wall addition.
• This surgical technique aims to improve acetabular component stability and restore joint congruity.
• Pre-operative and post-operative assessments were conducted to evaluate the outcomes.

Findings:

• Both patients achieved successful outcomes following socket wall addition.
• No further dislocations were reported in the seven and thirteen-month follow-up periods.
• The augmentation technique provided a stable construct and restored hip function.

Implications:

• Socket wall addition represents a viable surgical option for managing recurrent dislocations in revised total hip arthroplasty.
• This approach may help reduce revision rates and improve patient quality of life.
• Further studies with larger cohorts are warranted to confirm these findings.
