Abstract:
Objective To investigate the treatment and surgical results of acute volar plate avulsion fracture of proximal interphalangeal joint.Methods From August 2013 to June 2016,data of 15 cases of acute volar plate avulsion fracture of proximal interphalangeal joint were retrospectively analyzed.There were 8 males and 7 females aged 18-43 years old with an average of 28.6 years old.There were 4 cases of index finger,6 cases of middle finger,2 cases of ring finger and 3 cases of little finger.Eight injuries resulted from falls,four from finger breaking and three from crushing.The time from injury to operation was 5-9 days,with an average of 6.7 days.The acute volar plate avulsion fracture of proximal interphalangeal joint were treated by double thread compression suture fixation,and Kirschner wires were used to obliquely fix the interphalangeal joint.After the operation,the fore arm was fixed by plaster for 3-4 weeks.After the removal of the plaster,the flexion and extension function of the distal interphalangeal joint and the metacarpophalangeal joint was performed under the guidance of the rehabilitation instructor in a state of no weight.The finger was evaluated by X-ray every 2 weeks until the fracture healing.After 5-8 weeks,the Kirschner wire was removed when the fracture line disappeared,and the active flexion and extension of the proximal interphalangeal joint was guided by the rehabilitation instructor.Resuts In this group of 15 patients,all the incisions healed at the first stage.There was no surgical complications such as skin necrosis,and needle path infection and no abnormal finger feeling or blood circulation disorder.All patients were followed up for 8-32 months (mean,21.7 months).8 months after operation,the DASH score was 1.5 to 7.0 points with an average of 4.6 points.At the latest follow-up,there was no pain,swelling and joint contracture in the proximal interphalangeal joints.The dorsal extension of joints were stable,and the degree of active joint activity was:90°±7° of the metacarpophalangeal joint,80°±6° of the proximal interphalangeal joint,78°±7° of the distal interphalangeal joint,and 248°±22° of total active activity.According to TAM system assessment criteria:there was excellent in 12 cases,good in 2 cases,fair in 1 case,and excellent rate was 93.3％(14/15).Conclusion Double thread compression suture fixation for the treatment of acute volar plate avulsion fracture of proximal interphalangeal joints could reduce the damage to the accessory structure of the joint,and reach adequate exposure in the operationfor fixing the bone block firmly.After operation,good fracture healing and good finger function could be achieved,so the double thread compression suture fixation is an effective surgical method.
