Pedicle screw system reconstruction in shoulder resection type IV-total scapulectomy: A case report and short term follow up

New special approach for shoulder stability after Malawer type IVB shoulder girdle resection: A case report

Introduction and importance

Scapular prostheses are useful in shoulder stability after shoulder girdle resection for malignant bone tumors; however, they are difficult to obtain in Japan. Therefore, other methods must be considered, depending on the extent of resection. We report a case in which a clavicle-locking plate, Nesplon tape, and a proximal humeral prosthesis were used to ensure shoulder stability and preserve stable upper limb function.

Case presentation

A 56-year-old man presented with a large mass and edema over the entire right scapula, which caused severe pain, limited the shoulder's range of motion, and impaired function of the entire upper extremity. Clinical imaging and pathological findings indicated a diagnosis of conventional chondrosarcoma. Using the Malawer technique type IVB, we resected the shoulder girdle and secured shoulder stability with a clavicle-locking plate, Nesplon tape, and a proximal humeral prosthesis. To evaluate the patient, we obtained his Musculoskeletal Tumor Society (MSTS) and Disabilities of Arm, Shoulder, and Hand (DASH) scores 3 months postoperatively.

Clinical discussion

To preserve the function of the patient's elbow and hand, the stability of his shoulder was important. We could achieve this stability by using a prosthesis available in Japan. The patient's MSTT and DASH scores improved remarkably.

Conclusion

A clavicle-locking plate, Nesplon tape, and a proximal humeral prosthesis can be used to ensure shoulder stability after scapular girdle resection and can preserve or improve upper limb function.
