RESUMEN
Objective To observe the value of the high frequency color Doppler uItrasonography in emergency operation of flexor tendon injuries in the hand.Methods Totally 21 patients of flexor tendon injuries in the hand underwent surgical exploration with high frequency probe.The extent of the tendon injuries,the retracted parts of the ruptured tendon and the blood supply were observed.Results The extent of the tendon injuries,the poison of broken ends were clearly distinguished with high frequency probe.The continuous tendon fibrous of layered high echo and sheath thin layer low echo complete broke and replaced with low or no echo.Conclusion Intraoperative uhrasonography of flexor tendon iniuries is important tO shorten operation time,reduce the injury of surrounding tissues,relieve local adhesion and ensure vascular recanalization after operation.
