Total shoulder replacement surgery with custom glenoid implants for severe bone deficiency.

Area of Science:

• Orthopedic surgery
• Biomedical engineering
• Skeletal reconstruction

Background:

• Severe glenoid bone loss in shoulder arthritis presents treatment challenges.
• Medial and posterior bone loss compromises structural support for standard glenoid implants.
• Novel surgical techniques are needed for effective treatment.

Purpose of the Study:

• To evaluate the short-term outcomes of total shoulder replacement using custom inset glenoid implants in patients with severe glenoid bone deficiency.
• To assess the safety and efficacy of this novel approach.

Main Methods:

• Retrospective evaluation of seven consecutive patients (mean age 70) with severe glenoid bone deficiency (vault depth < 15 mm).
• Treatment involved custom inset glenoid implants without bone grafting.
• Follow-up included physical examination, radiographic studies, and outcome measures at a minimum of 3 years.

Main Results:

• No surgical complications were reported.
• Significant improvements observed in American Shoulder and Elbow Surgeon scores (68 points), range of motion, and pain reduction.
• Radiographic analysis classified all implants as "low risk" for glenoid loosening.

Conclusions:

• Custom inset glenoid implants offer a safe and effective solution for shoulder arthritis with severe glenoid bone loss.
• This technique provides a viable alternative when standard implants are contraindicated.
• Demonstrates a novel approach for reconstructing deficient glenoid bone.
