Endobutton plates demonstrate superior efficacy in treating unstable distal clavicle fractures

To compare the effectiveness of clavicular hook plates and Endobutton plates in treating unstable distal clavicle fractures (UDCFs).

Data from 95 patients with UDCFs (Neer II and V types) were retrospectively analyzed. Among them, 55 cases were treated with clavicular hook plates (control group), and 40 cases with Endobutton plates (research group). Comparative analyses included intraoperative indicators (incision length, intraoperative blood loss, operation time), postoperative recovery metrics (fracture healing time, fracture displacement distance, hospitalization time), pain assessment (Visual Analogue Scale [VAS]), shoulder joint function (American Shoulder and Elbow Surgeons [ASES] questionnaire), postoperative complications (plate loosening, recurrent fractures, incision infection, and fracture end redisplacement), and overall clinical efficacy.

The research group demonstrated significantly shorter incision lengths, comparable intraoperative blood loss, longer operation times, and shorter fracture healing times compared to the control group (all P < 0.05). No significant differences were observed in fracture displacement distance or hospitalization time (both P > 0.05). However, VAS scores were significantly lower, while ASES scores (pain, function, and total) were notably higher in the research group (all P < 0.05). The incidence of postoperative complications was similar between the groups (P > 0.05), but the excellent and good treatment rate was significantly higher in the research group (P < 0.05).

Endobutton plates offer significantly better clinical outcomes compared to clavicular hook plates for treating UDCFs, demonstrating advantages in postoperative recovery, pain management, and functional improvement.
