Bone benign fibrous histiocytoma (BFH) is an invasive primary bone tumor. When the local excision is not complete, the risk of recurrence is high, and hence, one-piece resection is necessary. The major challenge for clinicians is to reconstruct the bone after resection of the tumor. The present study investigated the efficacy of 3-dimensional (3D) printing technique in the treatment of benign fibrous histiocytoma of the scapula.


The patient with benign fibrous histiocytoma of scapular bone was treated with PEEK (polyetheretherketone) prosthesis replacement using the 3D printing technique. X-ray and computed tomography (CT) scans evaluated the relationship between the position of the prosthesis and that of the shoulder joint. Also, the constant score of the shoulder joint was calculated.


The anteroposterior radiograph showed that the position of the left scapula prosthesis is satisfactory and that of the shoulder joint is normal. Three months after the operation, the X-ray examination indicated the lack of flexibility and shift, as well as, dislocation and disjunction of PEEK prosthesis. The constant score of the left shoulder function was 68 points. Active shoulder joint activity: 120° on the lift, 90° on abduction, 50° on the external rotation, and 70° on internal rotation.


The application of 3D-printed PEEK scapula prosthesis with total shoulder replacement offers the possibility of accurate reconstruction, improves the operability of surgery, shortens the operation time, and allows early functional recovery of the patients.
