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

INTRODUCTION: Shoulder resection remains a challenging procedure after scapulectomy for tumour resection. The results have various functional outcome, wound coverage, and cosmetic aspect. In this case report, we reported the outcome of pedicle screw application after scapulectomy procedure within 1 month follow up after surgical tumour excision.

CASE PRESENTATION: A 74-year-old female presented with a painful lump on the left shoulder since nine months before admission. We performed physical examination, radiological evaluation using x-ray and MRI. We performed limb salvage surgery with shoulder girdle resection of tumour procedure using Malawer technique type IVB and applied pedicle and screw in proximal end clavicula and proximal end of humerus. We performed histopathological examination to ensure the tumour. We evaluated the patient one month after surgery using DASH score.

DISCUSSION: MRI examination revealed that there was a solid mass with malignant characteristic destructing left scapular bone with the acromioclavicular and glenohumeral joint involvement. We used pedicle and screw to reconstruct the patient with efficient cost spending consideration. Clinical valuation showed there was no pain left and hand-free movement except the limitation of shoulder abduction. DASH score evaluation pre operative and post operative showed improvement from 70.8 to 45.0.

CONCLUSION: Limb salvage procedure using pedicle screw system may be one of treatment of choice for treating tumour of the shoulder affecting glenohumeral joint with excellent result of evaluation both clinical and functional outcome.
