The resolution of protrusio acetabuli treated with Ring's hip prosthesis

Area of Science:

• Orthopedic surgery
• Biomedical engineering

Background:

• Protrusio acetabuli is a condition characterized by inward protrusion of the acetabulum.
• Painful protrusion can significantly impact patient mobility and quality of life.

Purpose of the Study:

• To report outcomes of Ring's prosthesis for protrusio acetabuli.
• To evaluate the efficacy and safety of Ring's prosthesis in treating this condition.

Main Methods:

• Retrospective case series of seven patients.
• Surgical hip replacement using Ring's prosthesis.
• Assessment of protrusion resolution and clinical outcomes.

Main Results:

• Complete or partial resolution of acetabular protrusion observed in all seven hips.
• Ring's prosthesis facilitated healing of the acetabular medial wall.
• The procedure was associated with avoidance of complications common to other treatments.

Conclusions:

• Ring's prosthesis provides a simple and effective treatment for painful protrusio acetabuli.
• This surgical option promotes acetabular wall healing while minimizing risks.
