- Abstract: Objective To explore the anatomical basis and clinical effect of radical styloid process bone(membrance)flap pedicled with the recurrent branch of radial artery to styloid process for repairing carpal scaphoid fracture.Methods The equal lengths of the radial styloid process in 25 adult radial specimens were measured.A latex-perfused male adult upper limb specimen was dissected to observe the course and distribution of the recurrent branch of radial artery to styloid process.The clinical data of 15 patients with carpal scaphoid fracture repaired by transposition and implantation of radical styloid process bone(membrance)flap pedicled with the recurrent branch of radial artery to styloid process were retrospectively analyzed,and the therapeutic effect was analyzed.Results The length of the radial styloid process measured on 25 radial specimens was 11 to 16 mm.Dissection of the latex-perfused male adult upper limb specimens revealed:the radial artery in the snuffbox emitted a thicker dorsal carpal branch to the ulnar side at(1.2±0.2)cm below the styloid process,and then sent a branch proximally back to the styloid process.The fracture line of 15 patients disappeared after surgery,with a fracture healing rate of 100%,and a mean healing time of 12 weeks;the Krimmer wrist joint function score showed that 6 cases were excellent,7 cases were good,and 2 cases were acceptable,with excellent and good rate of 86.7%;patients had lower postoperative pain visual analogue scale scores compared with those before surgery,the difference was significant(P<0.05).Conclusion Measuring the radial styloid process of the physical specimen and observing the course and distribution of the recurrent branch of radial artery to styloid process in adult upper limb specimens can guide the formulation of surgical plan for the treatment of carpal scaphoid fractures in clinic.The transposition and implantation of radical styloid process bone(membrance)flap pedicled with the recurrent branch of radial artery to styloid process can effectively promote fracture healing,and reduce the risk of delayed healing,which has good postoperative recovery of wrist joint function and definite clinical effect in the treatment of carpal scaphoid fractures.
