RESUMEN
OBJECTIVE@#To investigate clinical outcomes of countertraction method in treating irreducible subcoracoid dislocation of shoulder joint combined with Hill-Sacks injury.@*METHODS@#A total of 56 patients with irreducible subcoracoid dislocation of the shoulder joint combined with Hill-Sacks injury admitted from December 2013 to June 2020 were retrospectively analyzed. Under the anesthesia of shoulder joint cavity injection, the reduction was performed by using anti-traction method (experimental group) and traditional Hippocrates method (control group), 28 cases in each group. There were 11 males and 17 females in experimental group, with an average age of (61.95±19.32) years old, 9 cases on the left side, and 19 cases on the right side. Twelve males and 16 females in control group, with an average age of (63.13±12.75) years old, 11 cases on the left side, 17 cases on the right side. The curative effects between two groups were evaluated before and after operation, including the success rate of reduction, the duration of reduction, the distance from successful reduction to injury, complications and functional rehabilitation(Constant score of shoulder joint).@*RESULTS@#The success rates of reduction in experimental group and control group were 92.86%(26/28) and 67.86% (19/28), respectively, and the difference was statistically significant (P<0.05). The duration of simple reduction was (4.25±2.13) min and ( 6.31±1.69) min, the difference was statistically significant (P<0.05);the time from successful reduction to injury was (9.16±0.94) h and (8.94±1.31) h, respectively, with no significant difference(P>0.05). There were no complications such as vascular nerve injury and fracture in experimental group, 2 cases of axillary nerve injury and 1 case of humeral head fracture in control group. Constant scores of shoulder joint between experimental group and control group were (92.34±5.62) points and (90.91±4.73) points, respectively, with no significant difference (P>0.05).@*CONCLUSION@#For patients with irreducible subcoracoid dislocation of the shoulder joint with Hill-Sacks injury, the countertraction method under anesthesia of the shoulder joint cavity achieved a higher success rate and few complications.
