Novel sternoclavicular hook-plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular joint / 中国骨伤

ABSTRACT

OBJECTIVE@#To explore the efficacy of a novel sternoclavicular hook-plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular joint.@*METHODS@#Retrospective analysis of 13 cases of proximal clavicle fracture with dislocation of sternoclavicular joint treated with sternoclavicular hook-plate from June 2011 to January 2019 in our department. There were 9 males and 4 females, aged 26 to 78 years old, with an average age of (54.08±13.91) years old. All the patients had closed injuries without damage of blood vessels and nerves. The patient's operation time, intraoperative blood loss, hospital stay time, and postoperative complications were recorded. Fracture healing and reduction were evaluated according to X-ray and CT after operation. Constant-Murley score and Rockwood sternoclavicular joint score were used to evaluate limb function at 12 months after operation.@*RESULTS@#All the patients were treated with sternoclavicular hook-plate. The operation time ranged from 50 to 76 min, with a mean of (54.08±13.91) min. The intraoperative blood loss ranged from 20 to 56 ml, with a mean of (46.08±11.15) ml. The hospital stay time ranged from 6 to 14 d, with a mean of (8.31±2.32) d. X-ray and CT examination on the second day after operation showed that all fractures and dislocations were anatomically reduced, and shoulder joint function exercise was performed early. All patients were followed up, and the duration ranged from 12 to 24 months, with a mean of (16.77±4.63) months. The healing time ranged from 9 to 13 d, with a mean of (11.00±1.75) d;and the bone healing time ranged from 3 to 4 months, with a mean of (3.65±0.46) months. There were no complications such as infection, internal fixation failure and nerve injury. At 12 months follow-up, the constant Murley score ranged from 78 to 100, with a mean of 87.83± 11.26; and Rockwood score ranged from 9 to 15, with a mean of 13.70±1.85. Among them, 11 cases were excellent, 1 case was good, and 1 case was general.@*CONCLUSION@#The use of the novel sternoclavicular hook-plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular joint is an effectively internal fixation with high safety, allowing early functional exercise for patients.
