Comparison between locking plate and suture technique and hollow pull screw technique in fixation of humeral tubercle fracture

【Objective】To compare the mechanical stability of humeral tubercle fracture with locking plate plus suture technique and hollow pull screw fixation,and to explore the optimization of internal fixation of humeral tubercle fracture.【Methods】Fifty-two patients with humeral tubercle fracture in Xinyang Traditional Chinese Medicine Hospital from January 2015 to April 2019 were divided into two groups according to random digital table method.The control group was fixed with semithreaded cancellous bone hollow nail.The observation group was fixed with small locking plate and assisted non-absorbable suture to suture rotator cuff on the plate.The external fixation time and rehabilitation exercise were the same in the two groups.The loss of internal fixation,displacement distance above the greater tuberosity fracture block after failure,incidence of acromion impact were observed and compared between the two groups.【Results】The loss of internal fixation in the observation group was significantly smaller than that in the control group,resulting in the incidence of acromion impact less than that in the control group(P<0.05).Six months after operation,the excellent and good rate of shoulder function score was higher in the observation group than in the control group(P<0.05).【Conclusion】The fracture stability of locking plate fixation fracture block is significantly higher than that of hollow screw fixation,and the patients can receive more intensive functional exercise earlier after operation.
