Semiconstrained elbow prostheses with special reference to the GSB III prosthesis.

Area of Science:

• Orthopedic Surgery
• Biomaterials Engineering

Background:

• Fully constrained metal-to-metal elbow prostheses are largely obsolete due to high loosening rates.
• Current options for elbow joint replacement include semiconstrained and condylar prostheses, both associated with significant complication rates.

Purpose of the Study:

• To evaluate the efficacy and complication rates of the Gschwend-Scheier-Bähler (GSB) III semiconstrained elbow prosthesis.
• To compare the outcomes of the GSB III prosthesis with other available elbow replacement options.

Main Methods:

• Analysis of recent world literature on elbow prostheses.
• Review of clinical outcomes, including pain relief, range of motion, and complication rates associated with the GSB III prosthesis.
• Evaluation of the surgical approach and salvage techniques for failed arthroplasty.

Main Results:

• The GSB III prosthesis demonstrates satisfactory pain relief and improved range of motion in a high percentage of patients.
• This semiconstrained prosthesis requires minimal bone resection, facilitating easier salvage.
• The complication rate associated with the GSB III prosthesis is lower compared to many other elbow prostheses.
• The transtricipital approach and humeral condyle reconstruction method contribute to a high success rate and improved salvageability.

Conclusions:

• The GSB III semiconstrained elbow prosthesis is a viable option for elbow joint replacement, offering good functional outcomes and a lower complication profile.
• Its design and surgical approach contribute to successful outcomes and effective salvage in cases of failed arthroplasty.
