Outcomes of acromioclavicular joint dislocation using tightrope arthroscopy.

BACKGROUND: Based on different treatment outcomes and different treatment methods for acromioclavicular dislocation, we decided to evaluate the treatment outcomes of acromioclavicular joint dislocation using tightrope arthroscopy. METHODS: This retrospective cross-sectional study was performed on patients with acromioclavicular joint dislocation referred to Alzahra Hospital in Isfahan and Abadan-Iran from 2015 to 2017. Information that was assessed included age, sex, type of dislocation (Figure 1), duration of injury, cause of injury, complications such as osteoarthritis, changes in the distance between the joints, as well as the American Shoulder and Elbow Surgeons Shoulder Score (ASES) were collected after 6 months of surgery. RESULTS: There was a significant relationship between horizontal change instability and type of injury that 9 cases (60%) of type 5 of injury and 0 of type 3 had horizontal change instability (P=0.01). There was a reverse significant correlation between ASES score and duration of injury (r=-0.58, P=0.01). CONCLUSION: Acromioclavicular joint dislocations could successfully be treated with the TightRope system. We also showed that patient's pain and functions are diversely correlated with injury durations.

Outcomes of patients with humerus fracture under treatment with PHILOS plate.

BACKGROUND: Based on the contradictory results about the effect of an intramedullary nail in the treatment of humeral shaft fracture, in this study, we aim to evaluate the outcomes of patients with humeral fracture treated with PHILOS plaque. METHODS: In this cross-sectional study, which was performed to evaluate the recovery rate of patients with humeral fracture treated with PHILOS plaque referred to Shahid Beheshti Hospital in Abadan-Iran during 2015-2019. Constant Shoulder Score was evaluated six months and one year after the operation. RESULTS: The mean constant shoulder score was increased significantly after 1 year compared to 6 months (P<0.001). The means of constant shoulder score 6 months in type 4 of fracture was significantly higher than type 3 of fracture (P=0.03) but there was no significant relationship between the means of constant shoulder score 1 year after surgery and type of fracture. CONCLUSION: We suggest that orthopedic surgeons should pay more attention to the usage of PHILOS plate in patients with humerus fractures especially the type 4 fracture.
