Efficacy of anatomical locking plate combined with anchor nail in the treatment of Neer II distal clavicle fracture

Abstract

Objective To observe the efficacy of anatomical locking plate combined with anchor nail internal fixation and clavicular hook plate in the treatment of Neer Ⅱ distal clavicle fracture and their impact on shoulder function. Methods Eighty patients with Neer Ⅱ distal clavicular fracture treated in the Eighth People’s Hospital in Shanghai from January 2015 to December 2016 were divided into observation group and control group, each group 40 cases.The observation group was treated with anatomical locking plate combined with anchor nail, the control group was treated with clavicular hook plate.The efficacy, operation time, intraoperative blood loss, fracture healing time, postoperative hospital stay, shoulder function score and incidence of complication were observed in the two groups. Results The excellent rate was in the observation group was higher than that in the control group (97.50%(39/40) vs.80.00%(31/40), χ2=2.477, P 0.05); the fracture healing time in the observation group was longer than that of the control group ( (23.65±2.19) w vs.(26.9±3.46) w, P<0.01). The shoulder joint Constant-Murley score in the observation group was (86.02±5.19) points, control group (68.46± 6.94) points, the difference was statistically significant (P<0.01). Observation group showed 2 cases of pain around acromion, the incidence rate of complications was 5.00%(2/40); 7 cases in the control group had pain around acromion, 2 cases suffered from impingement syndrome and 1 cases had delayed union, the incidence rate of complications was 25.00% (10/40). Conclusion Anatomical locking plate combined with anchor nail internal fixation is effective in the treatment of Neer II distal clavicle fracture.It has the advantages of fast fracture healing, good functional recovery of shoulder joint and less complications.
