Abstract:
Objective To compare the clinical effect between cannulated compression countersunk head screws(CS)and anatomical locking compression hook plate(LCP)for fractures of proximal fifth metatarsal bone at Lawrence zone Ⅰ.Methods A total of 60 patients with fractures of proximal fifth metatarsal bone at Lawrence zone Ⅰ from May 2021 to May 2023 were retrospectively analyzed.Of them,20 patients were treated by internal fixation with cannulated compression countersunk head screws(CS group),and other 40 patients were treated by internal fixation with anatomical locking compression hook plate(LCP group).The postoperative therapeutic effects were evaluated by using the Visual Analogue Scale(VAS)and the American Orthopaedic Foot and Ankle Society(AOFAS)Midfoot Scale.Incidences of postoperative complications were also recorded.Results The operations were successfully completed in all the 60 patients.The operation time in the CS group was shorter than that in the LCP group[37(15-74)min vs.50.5(28-102)min,P=0.002].The VAS score in the CS group immediately after surgery was lower than that in the LCP group[3(2-5)vs.4(2-5),P=0.004],and there was no significant difference between the two groups at 3,6,and 12 months after surgery and at the last follow-up(P＞0.05).At the 3rd month after operation,the AOFAS score in the CS group was better than that in the LCP group[52(23-62)vs.49(23-62),P=0.038],and there was no significant difference between the two groups at 6 and 12 months after surgery and at the last follow-up(P＞0.05).In the LCP group,there were 1 case of superficial wound infection,3 cases of long-term chronic pain,6 cases of foreign body sensation,5 cases of removal of the internal fixation by a second operation after one year postoperatively.In the CS group,there was only 1 case of foreign body sensation.Conclusions Both cannulated compression countersunk head screws and anatomical locking compression hook plate can effectively fix fractures of proximal fifth metatarsal bone at Lawrence zone Ⅰ.Compared with anatomical locking compression hook plate,cannulated compression countersunk head screws can shorten operation time,reduce postoperative pain,and facilitate early functional rehabilitation.
