To evaluate the clinical and radiographic outcomes of arthroscopic Chinese Unique Inlay Bristow procedure (Cuistow procedure) and arthroscopic Bristow procedure in treating recurrent anterior shoulder instability.
Aim: To compare the clinical and radiographic outcomes following the arthroscopic Chinese Unique Inlay Bristow (Cuistow) procedure and the arthroscopic Bristow procedure. Background: The Cuistow procedure is a modified Bristow surgery in which a Mortise and Tenon structure was added to the contact surface between the coracoid tip and the glenoid. In previous study, patients received Cuistow procedure have satisfying clinical performance and excellent postoperative bone healing rate (96.1%). However, no comparative studies was performed. Study Design: Retrospective comparative case-cohort study Methods: Patients who underwent the arthroscopic Cuisotw procedure and modified Bristow procedure between Jan 2017 and Mar 2018 were selected. 70 patients with recurrent anterior shoulder instability were included. Radiological evaluations with 3D CT scan were performed preoperatively, immediately after the operation, and postoperatively at three months and during the final follow-up (more than 2 years). Clinical assessment for a minimum of 24 months including the 10-point visual analog scale for pain and subjective instability, University of California at Los Angeles scoring system (UCLA score), American Shoulder and Elbow Surgeons score (ASES score), ROWE score, Subjective Shoulder Value (SSV) and active range of motion were completed by independent observers and analyzed.

Bone union rate
Bone healing was observed in 3D-CT. The bone healing rate was obtained by dividing the number of people who achieved bone healing by the total number of people.
Time frame: 3-month postoperatily
Bone union rate
Bone healing was observed in 3D-CT. The bone healing rate was obtained by dividing the number of people who achieved bone healing by the total number of people.
Time frame: 2-year postoperatily
ASES score
The ASES score (Michener 2002) is a 10-item measure of shoulder pain and function. Pain is assessed on a 10-cm visual analog scale (VAS) and accounts for 50% of the total score. The remaining 50% of the score is determined by the responses to 10 4-point Likert-scale questions related to physical function.
Time frame: 2-year postoperatively
dislocation rate
The dislocation rate was obtained by dividing the number of people who dislocated postopratively by the total number of people.
Time frame: 2-year postoperatively
VAS for pain score
The visual analog scale (VAS) for pain score is the most commonly used to describe pain levels in patients, ranging from 0 to 10, with a higher score indicating more intense pain.
Time frame: 2-year postoperatively
Active shoulder ranges of motion
internal rotation at the side, and external and internal rotation at 90° of abduction
Time frame: 2-year postoperatively
