This article has reviewed recurrent carpal tunnel syndrome, epineural fibrous fixation, and traction neuropathy of the median nerve. The problems surrounding the diagnosis and treatment of recurrent CTS have been discussed at length. The percent of failures from traditional open ligament surgery is observed to be high, and will become more prevalent as more casual treatments are carried out. This article makes a positive statement with reference to mobilization of the median nerve and anatomic restoration of the transverse carpal ligament. Fibrous fixation of the median nerve is a product of life and function. All cases are different, reflecting the strength, abilities, and personalities of the patients. A bottom line is drawn on these patients, where the summation of the problems of life become symptomatic and disabling. Epineural fibrous fixations induce median nerve traction, governed by hand, wrist, and forearm movements. Traction and tension suggest the intermittent disturbance of nerve nutrition and nerve conduction as the elastic limits of the nerve are approached. These factors accumulate and, in time, cause traction neuropathies with pain. This is followed by a reduced work capability. This impairment can be reversed by surgical nerve mobilization followed by functional nerve gliding therapy. A background history injury to the hand and wrist may be significant, as well as factors such as overuse and misuse of the hand and extremity. Prior to surgery, the careful application of diagnostic stress tests are essential, for the differential diagnosis of fixation traction and positional peripheral neuropathies. Nerve mobilization supported by magnification and the techniques of hand surgery has been successful by the methods discussed and has permitted, importantly, the restoration of the anatomic retinaculum for the flexor tendon system. This can be restored in carpal tunnel surgery and reconstructed with basic ligament material in recurrent carpal tunnel surgery.
本文回顾了复发性腕管综合征、神经外膜纤维固定以及正中神经牵拉伤。文中详细讨论了围绕复发性腕管综合征诊断和治疗的问题。传统开放性韧带手术的失败率较高,随着更多随意治疗的开展,这一情况将变得更加普遍。本文对正中神经的松动以及腕横韧带的解剖修复持肯定态度。正中神经的纤维固定是生活和功能的产物。所有病例各不相同,反映了患者的力量、能力和个性。针对这些患者得出了一个底线,即生活中的各种问题累积起来会出现症状并导致残疾。神经外膜纤维固定会引发正中神经的牵拉,这种牵拉受手部、腕部和前臂运动的影响。当接近神经的弹性极限时,牵拉和张力表明神经营养和神经传导会受到间歇性干扰。这些因素不断累积,最终导致伴有疼痛的牵拉伤。随后工作能力会下降。通过手术松解神经并进行功能性神经滑动治疗,这种损伤是可以逆转的。手部和腕部既往的损伤病史可能很重要,过度使用和误用手部及肢体等因素也同样重要。在手术前,仔细应用诊断性应力测试对于鉴别固定性牵拉伤和体位性周围神经病变至关重要。通过文中讨论的方法,在放大设备支持下的神经松动术以及手部手术技术已取得成功,并且重要的是,这使得屈肌腱系统的解剖支持带得以恢复。在腕管手术中可以恢复这一结构,而在复发性腕管手术中则可用基本的韧带材料进行重建。
