肌肉撕裂：动态超声检测带来的准确性

根据最新的一项研究，动态超声检测对肌肉撕裂和血肿诊断、处理来说是一种非常有用的工具。

来自阿曼Khoula医院的科学家主持了这项研究。研究对象为50名足球运动员，年龄在20-30岁之间，在大腿和小腿上都有肌肉撕裂。受伤侧和对侧都进行了相关的检测。

超声对所有运动医疗急症室来说，是迅速且无放射性的成像工具。对于诊断和处理肌肉撕裂来说也是一种非常重要的工具。本研究的第一作者Ashok Kumar Nath解释道。

50个病人中，46 例在大腿和小腿区域有肌肉撕裂和/或血肿。32例病人肌肉完全撕裂周围有明显的血肿，剩下的14例部分撕裂，损伤具有回声性质，并且肌肉是松弛的，类似于肌肉收缩时的假-肿瘤。根据此项研究，愈合后的伤口是具有高度反射性的瘢痕组织。

“我们对肌肉撕裂进行动态超声检测，并且我们的研究对象因此检查在肌肉撕裂诊断和治疗上获益。”Nath博士说，“如果我们认为伴有血肿的肌肉撕裂需要进行引流，我们可在超声图像的指导下对病人进行更准确和科学的措施。”


Muscle Tears: Dynamic Sonography Diagnoses Accurately 
   
Dynamic sonography is a useful tool in the diagnosis, management and follow-up of muscle tears and haematomas, according to a recent studyThe ultrasound research was conducted by scientists from Khoula Hospital in Muscat, Oman. The study consisted of 50 male soccer players ranging from 20 to 30 years of age with muscular trauma in the thigh and calf. Dynamic sonography of both the affected and contralateral normal part was performed.
 
“Ultrasound is a rapid and radiation free imaging modality available in all sports medicine emergency rooms. It is a very important tool to diagnose, follow-up and document muscle tears for proper management,” said Ashok Kumar Nath, MD, lead author of the study.
 
Of the 50 patients, 46 had muscle tears and/or haematomas in the thigh and calf regions. Thirty-two of those patients had clear-cut complete muscle tears surrounded by haemotomas and the remaining 14 patients had partial tears, appearing as hypoechoic subtle lesions with relaxed muscle which looked like pseudo-tumours on contraction. According to the study, the healed tears appeared as highly reflective scar tissue. 

“We are successfully performing dynamic sonography in muscular trauma and our players have benefited tremendously in the management and follow-up of muscle tears,” said Dr. Nath. “If we find muscle tears with haematomas which need to be drained, we perform the drainage under ultrasound image guidance which is more accurate and scientific,” he said.
