Arthroscopic single portal - single row knotless repair of subscapularis tendon tear: Technical note.

The subscapularis (SSc) is the most powerful muscle of the rotator cuff. His role in shoulder stability and shoulder motion is well studied and due to functional and frequent association with concomitant other lesions, the repair of the SSc tendon is always desirable to restore force and stability to the shoulder.

Use of a Dry Surgical Simulator Improves Orthopaedic Residents' Competency and Technical Skills for Arthroscopic Rotator Cuff Repair.

Purpose: To evaluate whether an anatomic dry shoulder Dexter training model surgical simulator would be effective in augmenting orthopaedic residents' skills for arthroscopic rotator cuff repair. Methods: Nine residents, enrolled for this prospective study, watched a video presentation about transosseus equivalent (TOE) double-row, rotator cuff repair technique, repeating the aforementioned technique twice on the simulator. The time to complete all steps to final repair, as well as the quality of the final repair, were measured. Results: The data for repair completion time showed a statistically significant difference in the total duration time of performing the procedure, when comparing the timing in tests 1 and 2, demonstrating a reduced operative time. The qualitative data collected show an increase in the final score in 100% (9 out of 9) of the participants between the first and second tests, with an improvement in the average score of 16.4% (3.22 points with a standard deviation of 2.64). Hence, there is a statistically significant difference (P = .006) between the total scores obtained by the participants at the end of tests 1 and 2, presenting an improvement of the quality score, shifting from the first (average score 19.7) to the second (average score 22.9) test. Conclusion: The dry simulator may be a valuable device to improve arthroscopic technical skills. This improvement was observed both in the resulting reduced operative time required to carry out the surgical procedure and the increased quality score (established to evaluate the quality of the required tasks). Clinical Relevance: In order to provide as many training opportunities as possible, an arthroscopy simulator could be used to supplement clinical arthroscopy skills training for orthopaedic residents.

Fracture Avulsion of the Greater Tuberosity: Arthroscopic Transosseous Augmented Technique.

The fracture avulsion of the greater tuberosity (GT) represents 2% of all humerus fractures, but the true incidence is likely to be higher, being challenging the initial diagnosis on radiograph. The fracture avulsion of the GT could have different treatments: nondisplaced or minimally displaced fractures are treated conservatively, whereas for displaced or comminuted fractures surgical treatment is preferred. The most important finding of this study is the employment of an all-arthroscopic transosseous augmented technique for the treatment of a displaced humeral GT fracture avulsion. This technique shows all the advantages of the transosseous fixation and arthroscopic approach.
