Introduction: This case report describes the reconstruction of a severe
comminuted fracture and bone defect in the lateral half of the clavicle using a novel
titanium prosthesis. This unique
prosthesis has been specifically designed and three dimensionally printed for the clavicle, as opposed to the Oklahoma cemented composite
prosthesis used in common practice. The aims of this study were to: (1) describe the
prosthesis, its stress analysis, and its surgical fixation and (2) to demonstrate the results of the 2-year follow-up of the patient with the lateral clavicle
prosthesis. Patient's Main Concerns: A 20-year-old, right-handed woman complaining of severe
pain in the right shoulder was admitted to our hospital following a traffic accident. Physical examination revealed
pain, swelling, tenderness, limb weakness, asymmetric posturing, and loss of function in the right shoulder. Diagnosis, Intervention, and Outcomes: Radiographic evaluation in the emergency room showed complete destruction with a
comminuted fracture of the lateral half of the right clavicle and a
comminuted fracture of the coracoid. We designed a new
prosthesis for the lateral half of the clavicle, which was then tested by finite
element analysis and implanted. Use of the new
prosthesis was effective in the reconstruction of the
comminuted fracture in the lateral half of the clavicle. After 2 years of follow-up, the patient had an aesthetically acceptable curve and was able to perform her
activities of daily living. Her
pain was relieved, and the disabilities of the arm, shoulder, and hand score improved. Active range of motion of the shoulder joint and muscle strength were also improved. Conclusion: This novel
prosthesis is recommended for reconstruction of the lateral half of the clavicle following development of bony defects due to fracture. Our patient achieved functional and aesthetic satisfaction with this
prosthesis.
