We describe a new technique for treating traumatic brachial plexus avulsion injury with a contralateral C7 nerve transfer with direct coaptation that shortens the time to muscle reinnervation.
STEP 1 EXPLORE THE INJURED BRACHIAL PLEXUS: Explore the brachial plexus carefully and confirm the nerve-root avulsion injuries from C7 to T1.
STEP 2 HARVEST THE CONTRALATERAL C7 NERVE: Dissect the divisions of the contralateral C7 nerve root, divide the nerve at the junction between the divisions and cords, and mobilize it proximally.
STEP 3 CREATE THE PRESPINAL ROUTE: Create the prespinal route to guide the contralateral C7 nerve to the injured side.
STEP 4 HUMERAL SHORTENING OSTEOTOMY: If the contralateral C7 nerve does not reach the injured lower trunk, perform a humeral shortening osteotomy, generally with <5 cm of shortening in adults.
STEP 5 NEURORRHAPHY: Suture one end of the sural nerve together with the medial antebrachial cutaneous nerve to the musculocutaneous nerve; anastomose the remainder of the contralateral C7 nerve directly with the lower trunk.
STEP 6 POSTOPERATIVE CARE: Use a prefabricated brace to hold the head in the neutral position and immobilize the injured limb for six weeks.
We evaluated the results of the technique in a study of seventy men and five women with a mean age (and standard deviation) of 28 ± 10 years (range, ten to fifty-three years).IndicationsContraindicationsPitfalls & Challenges.
我们描述了一种治疗创伤性臂丛神经撕脱伤的新技术,即采用直接端端吻合的对侧C7神经移位术,该技术可缩短肌肉再支配时间。
步骤1 探查受伤的臂丛神经:仔细探查臂丛神经,确认C7至T1神经根撕脱伤。
步骤2 切取对侧C7神经:解剖对侧C7神经根的分支,在分支与束的交界处切断神经,并向近端游离。
步骤3 创建脊柱前通道:创建脊柱前通道,将对侧C7神经引导至受伤侧。
步骤4 肱骨缩短截骨术:如果对侧C7神经无法到达受伤的下干,则进行肱骨缩短截骨术,成人一般缩短<5 cm。
步骤5 神经缝合:将腓肠神经的一端与前臂内侧皮神经一起缝合至肌皮神经;将对侧C7神经的其余部分直接与下干吻合。
步骤6 术后护理:使用预制支具将头部保持在中立位,固定受伤肢体六周。
我们在一项研究中评估了该技术的结果,该研究纳入了70名男性和5名女性,平均年龄(及标准差)为28±10岁(范围为10至53岁)。适应症 禁忌症 陷阱与挑战。
