[Objective]To compare the clinical outcomes of double loop plate combined with compression screw(DLP)versus clavicular hook plate(HP)in the treatment of Neer type ⅡB distal clavicular fractures.[Methods]A retrospective study was done on 61 patients who re-ceived surgical treatment for Neer type ⅡB distal clavicular fractures from January 2020 to December 2022.According to the preoperative doc-tor-patient communication,30 cases were treated with DLP,while the remaining 31 patients were treated with the HP.The perioperative peri-od,follow-up and imaging data were compared between the two groups.[Results]The DLP group proved significantly superior to the HP group in terms of incision length[(4.5±0.4)cm vs(7.7±0.6)cm,P＜0.001],intraoperative blood loss[(46.7±6.9)ml vs(66.9±8.8)ml,P＜0.001]and active activity time[(25.4±1.5)days vs(30.0±1.8)days,P＜0.001],despite of the fact that the former consumed significantly longer opera-tive time than the latter[(69.5±7.8)min vs(62.7±7.7)min,P＜0.001].In addition,the DLP group regained full weight bearing activitysignifi-cantly earlier than HP group[(84.1±5.7)days vs(87.3±6.1)days,P=0.039].As time went on,VAS scores were significantly decreased(P＜0.05),whereas Constant-Murley scores,abduction-uplifting,forward flexion-uplifting and internal and external rotation range of motion(ROMs)of the shoulder significantly increased in both groups(P＜0.05).The DLP group proved significantly better than the HP group in abovesaid items at 3 months postoperatively and the last follow-up(PP＜0.05).As for imaging,fracture reduction quality in the DLP group was also significantly better than that in the HP group[excellent/good/poor,(19/10/1)vs(9/20/2),P=0.027].The postoperative coracoclavavicular distance(CCD)in both groups significantly reduced compared with that preoperatively(PP＜0.05),which in the DLP group was significantly smaller than that of in the HP group 3 months after the operation and the last follow-up(P＜0.05).However,there was no significant difference in fracture healing time between the two groups(P＞0.05).[Conclusion]Compared with traditional clavicular hook plate in the treatment of Neer type ⅡB distal clavicular fractures,double loops plate combined with compression screw has the advantages of minimally invasive sur-gery,less influence on postoperative joint function and fewer complications,and more satisfactory clinical consequences.
