Reverse geometry shoulder replacement for proximal humeral metastases

Area of Science:

• Orthopaedic Surgery
• Oncology
• Musculoskeletal Oncology

Background:

• Skeletal metastases, particularly in the proximal humerus, cause significant pain and disability in cancer patients.
• Management of these metastases presents challenges for orthopaedic surgeons, impacting patient morbidity.
• Proximal humeral metastases can lead to severe pain and loss of function, diminishing quality of life.

Purpose of the Study:

• To evaluate the efficacy of reverse geometry proximal shoulder replacement in managing proximal humeral metastatic disease.
• To assess the potential for pain relief and restoration of functional range of movement in rotator cuff deficient patients.
• To present a novel surgical strategy for a challenging orthopaedic oncology problem.

Main Methods:

• Retrospective case report of three patients with proximal humeral metastases and rotator cuff disease.
• Surgical intervention involved reverse geometry proximal shoulder replacement.
• Outcomes assessed included pain levels, functional range of movement, and surgical complications.

Main Results:

• All three patients experienced significant postoperative symptomatic relief.
• Upper limb function was preserved following the surgical intervention.
• No surgical complications were reported in any of the cases.

Conclusions:

• Reverse geometry proximal shoulder replacement is a valuable and effective option for managing proximal humeral metastatic disease.
• This approach is particularly beneficial in patients with concomitant rotator cuff deficiency.
• The strategy provides a pain-free, functional range of movement, improving patient outcomes.
