Anatomic Total Shoulder Arthroplasty With a Stemless Humeral Component

Area of Science:

• Orthopedic Surgery
• Arthroplasty Techniques
• Biomedical Engineering

Background:

• Anatomic total shoulder arthroplasty (TSA) is a surgical procedure to treat glenohumeral arthritis.
• Stemless humeral components offer an alternative to traditional stemmed implants in TSA.

Purpose of the Study:

• To review the technique for stemless anatomic total shoulder arthroplasty (TSA).
• To highlight indications, contraindications, and critical surgical steps for stemless TSA.
• To discuss early and mid-term outcomes and potential complications.

Main Methods:

• Review of a representative case example of stemless TSA.
• Description of preoperative planning (CT, MRI navigation).
• Detailed explanation of surgical technique: positioning, approach, osteotomy, implant placement, and fixation.

Main Results:

• Stemless TSA is indicated for younger patients (<65 years) with glenohumeral arthritis and good bone quality.
• The technique involves specific steps for humeral and glenoid preparation and implant insertion.
• Early and mid-term outcomes show complication rates, including loosening, similar to stemmed components.

Conclusions:

• Stemless TSA is a viable option for specific patient populations with glenohumeral arthritis.
• The procedure requires meticulous surgical technique and adherence to a rehabilitation protocol.
• Further research may focus on long-term outcomes and comparative studies with stemmed TSA.
