Developments in the Treatment of Midshaft Clavicle Fracture After Plate Fixation Failure: A Case Report with 2.5...

Background and Clinical Significance: Clavicular fractures account for approximately 2.6% of all fractures, with 80% of clavicular fractures occurring in the middle-third of the bone. The middle-third of the clavicle lies directly under the skin without any protection from soft tissue or muscle attachments. The purposes of this case report are as follows: (1) to represent the prosthesis and its operative implantation and (2) to assess the radiological and clinical outcomes of using the prosthesis after a 2.5-year follow-up of the patient; Case Presentation: We present the case of a midshaft clavicle fracture in a 26-year-old, right-handed, male patient following a failure of conservative and open reduction and internal fixation of the fracture. A three-dimensional (3D) customized prosthesis with polyamide was designed for the patient. The patient presented 2.5 years after surgery with a VAS score of 2 and a DASH score of 21, and radiographic evaluation revealed good prosthesis position and no evidence of a stress fracture or unanticipated complications; Conclusions: This is a single case with successful polyamide prosthesis fixation in the treatment of a midshaft clavicle fracture after the failure of plate fixation.
