Ruptured finger distal interphalangeal (DIP) collateral ligament is a rare injury, with controversial treatment until the present. Our case series aimed to demonstrate feasible surgical intervention using a mini anchor. The present study includes four patients with ruptured finger DIP collateral ligaments who received primary repair in a single institute. They have suffered from joint instability due to ligament loss caused by infection, motorcycle accidents, and work-related accidents. All patients were operated on similarly using a 1.0 mm mini anchor for ligament reattachment. The finger DIP joint range of motion (ROM) was documented in all patients during follow-up. Joint ROM recovered to almost normal degrees, and the pinch strength recovered to > 90% compared to the contralateral side in all patients. Additionally, collateral ligament re-rupture, DIP joint subluxation or re-dislocation, and infection were not noted during follow-up. Ruptured finger DIP joint ligament requiring surgery is usually based on a combination with other soft tissue injuries and defects. However, repair with a 1.0 mm mini anchor is a feasible surgical intervention to reattach the ligament with minimal complication. [ABSTRACT FROM AUTHOR]

Abstract: Nanofiber fabric is firstly introduced to replace common microfiber fabrics as the platform for flexible supercapacitors. Nanofiber and microfiber electrodes can be simply fabricated using a dipping process that impregnates reduced graphene oxide (RGO) nanosheets into electrospun polyamide-66 (PA66) nanofiber and microfiber fabrics. RGO nanosheets are tailored to various sizes and only RGO with a medium diameter of 250–450nm (denoted as M-RGO) can effectively penetrate the pores of nanofiber fabrics for constructing smooth conductive paths within PA66 nanofiber fabrics. The synergistic effect between suitable sizes of RGO nanosheets and nanofiber fabrics with a high specific area provides a symmetric supercapacitor composed of M-RGO/PA66 nanofiber fabric electrodes with high-volume and high-area specific capacitance (C S,V and C S,A, equal to 38.79Fcm−3 and 0.931Fcm−2 at 0.5Ag−1, respectively), which are much larger than that of a symmetric supercapacitor composed of RGO/PA66 microfiber fabric electrodes (8.52Fcm−3 and 0.213Fcm−2 at 0.5Ag−1). The effect of impregnating nanofiber fabrics with suitably sized RGO to promote C S,V and C S,A of flexible supercapacitors has been demonstrated. [Copyright &y& Elsevier]
