Tunnel Syndrome

The main objective of this pictorial essay is to illustrate the sonographic appearance of the postoperative carpal tunnel and median nerve. Carpal tunnel surgical treatment failures have been shown to occur in up to 19% of a large series requiring re-exploration. Surgical management options for recurrent carpal tunnel syndrome (CTS) include revision release, neurolysis, vein wrapping, and fat grafting procedures. While several descriptions of median nerve entrapment in CTS exist in the ultrasound literature, little is written regarding its postoperative appearance. We report the sonographic changes in the appearance of the median nerve and postoperative carpal tunnel.

Background. Nerve compression underlying carpal tunnel syndrome (CTS) results in an increase in the threshold of superficial sensation in the area supplied by the median nerve, which is a mixed nerve dominated by sensory fibres. The distribution of sensory symptoms is strongly dependent on the degree of electrophysiological dysfunction of the median nerve. The association between carpal tunnel syndrome and ulnar nerve entrapment at wrist level is still unclear. Patho­logical processes leading to median neuropathy in CTS may affect ulnar nerve motor and sensory fibers in the Guyon canal. This may explain the extra-median spread of sensory symptoms in CTS patients. Material and methods. The study involved 88 patients (104 hands), with 70 women (83 hands) and 18 men (21 hands) aged between 25 and 77 years. 50 age- and sex-matched subjects without carpal tunnel syndrome were used as a control group. The diagnosis of carpal tunnel syndrome was made according to the criteria of the American Academy of Neurology 1993 guidelines. Based on the results of an ENG trace evaluating the degree of conduction disturbances in the median nerve, the patients were classified to one of three severity subgroups. The threshold of sensory excitability to pulsed current was determined in a test with single 100 ms rectangular pulses. Conclusions. 1. The threshold of sensation in the fingers innervated by the median and ulnar nerve is significantly lon­ger in patients with CTS than in controls. 2. Surgical treatment decreases the threshold of sensation in the fingers innervated by the median nerve. 3. Surgical treatment does not decrease the threshold of sensation in the fingers innervated by the ul­nar nerve. 4. The preoperative and postoperative threshold of sensation in the fingers innervated by the median and ulnar nerve is significantly longer in patients with severe carpal tunnel than in mild and moderate cases.

Tunnel Syndrome

Background. Carpal tunnel syndrome is the most common tunnel neuropathy in which the median nerve is compressed at the level of the wrist in the carpal canal. Treatment of carpal tunnel syndrome can be conservative and surgical. Surgical treatment is indicated in case of ineffective conservative treatment. However, the strategy of managing patients with carpal tunnel syndrome in the postoperative period has not yet been determined; there is no clear understanding of the effectiveness and necessity of rehabilitation in the early and long-term postoperative periods.Aim. Follow-up the patients after decompression of the median nerve in the late (up to 3 weeks after surgery) and long-term (3 weeks after surgery) postoperative periods to assess the effectiveness of different methods of rehabilitation.Materials and methods. A randomized controlled study included 108 cases of idiopathic carpal tunnel syndrome (unilateral and bilateral). After surgery, the patients were divided into three groups: the restorative treatment group using magnetic therapy, the kinesiotherapy group, and the control group. Clinical, neurophysiological and ultrasound monitoring was carried out for six months.Results. Patients of all the groups showed similar improvement in the most of the analyzed parameters, without any significant difference.Conclusion. Thus, according to the results of a comprehensive study, it is evident that early diagnosis of carpal tunnel syndrome and a high-quality surgical decompression of the median nerve with a complete dissection of the flexor retinaculum of the hand guarantee improvement within six months or later after surgical treatment without additional rehabilitation measures.

We report the use of a hypothenar pedicled fat flap to cover the median nerve in recalcitrant carpal tunnel syndrome. Forty-five patients with recurrent symptoms after previous carpal tunnel surgery were included in this study. Patients with incomplete release of the transverse carpal ligament were not included. We performed an anatomical study on 30 cadavers. The original technique with the section of the deep branch of ulnar artery was modified. The flap could be transferred onto the median nerve without stretching. The median follow-up was 45 months (range, 12–80 months). Pain completely disappeared in 41 patients with normal nerve conduction. Based on clinical and electromyographic signs, the global results showed excellent results (49%), 19 good results (45%), two average results (4.5%) and two failures (2%). The use of a hypothenar pedicled fat flap to cover the median nerve in recalcitrant carpal tunnel syndrome is a simple and efficient technique which improves the trophic environment of the median nerve and relieves pain.

Pain Symptoms

Carpal tunnel syndrome is the most common nerve compression disorder of the upper extremity, and it is traditionally considered a peripheral neuropathy associated with a localized compression of the median nerve just at the level of the carpal tunnel. Surgery and physiotherapy are treatment approaches commonly used for this condition; however, conflicting clinical outcomes suggest that carpal tunnel syndrome may be more complex. There is evidence supporting the role of peripheral nociception from the median nerve in carpal tunnel syndrome; however, emerging evidence also suggests a potential role of central sensitization. The presence of spreading pain symptoms (e.g. proximal pain), widespread sensory changes, or bilateral motor control impairments in people presenting with strictly unilateral sensory symptoms supports the presence of spinal cord changes. Interestingly, bilateral sensory and motor changes are not directly associated with electrodiagnostic findings. Other studies have also reported that patients presenting with carpal tunnel syndrome exhibit neuroplastic brainstem change supporting central sensitization. Current data would support the presence of a central sensitization process, mediated by the peripheral drive originating in the compression of the median nerve, in people with carpal tunnel syndrome. The presence of altered nociceptive gain processing should be considered in the treatment of carpal tunnel syndrome by integrating therapeutic approaches aiming to modulate long-lasting nociceptive barrage into the central nervous system (peripheral drive) and strategies aiming to activate endogenous pain networks (central drive).

Introduction Although surgical treatment of carpal tunnel syndrome (CTS) is known to be highly effective outcomes may not be equally satisfactory for the patients due to severity of clinical presentation and objectifying assessment of the condition. Purpose Provide clinical evaluation of outcomes of surgical treatment of CTS using questionnaires and electroneuromyography (ENMG) findings depending on baseline severity of the condition. Material and methods The review included 161 patients who underwent 189 operations of open decompression of the median nerve using mini-access. The patients were assigned to three groups with mild (Group I), moderate (Group II) and severe (Group III) CTS. Evaluations were produced at 6 weeks, 3, 6 and 12 months following the surgery. Results The majority of patients showed positive dynamics, and delayed recovery of the wrist function was noted in Group III at a 12-month follow-up. Patients of Group III exhibited spasmodic improvement of the wrist function at 6-week-to-3-month follow-up. Conclusion Open decompression of the median nerve performed for patients with CTS using mini-approach facilitated substantial clinical and functional improvement in most cases. However, the most favorable results could be provided for mild and moderate CTS.

Perineural Fibrosis

Revision carpal tunnel surgery varies from 0.3% to 19%. It involves a delayed neurolysis and prevention of perineural fibrosis. Despite numerous available procedures, the results remain mediocre. The aim of this study is to evaluate the results of the Canaletto implant in this indication. Our series includes 20 patients (1 bilateral affection) reoperated for carpal tunnel between October 2008 and December 2009. After the first operation, the symptom-free period was 112 weeks, on average. The average incision was 27 mm. After neurolysis, the Canaletto implant was placed in contact with the nerve. Immediate postoperative mobilization was commenced. Sensory (pain, DN4, and hypoesthesia), motor (Jamar, muscle wasting), and functional (disabilities of the arm, should, and hand; DASH) criteria were evaluated. Nerve conduction velocity (NCV) of the median nerve was measured. Average follow up was 12.1 months. All measurements were improved after insertion of the Canaletto implant: pain (6.45–3.68), DN4 (4.29–3.48), Quick DASH (55.30–34.96), Jamar (66.11–84.76), NCV (29.79–39.06 m/s), hypoesthesia (76.2–23.8%), wasting (42.9–23.8%). Nevertheless, four patients did not improve, and pain was the same or worse in six cases. Our results show that in recurrent carpal tunnel syndrome, Canaletto implant insertion gives results at least as good as other techniques, with the added advantage of a smaller access incision, a rapid, less invasive technique, and the eliminated morbidity of raising a flap to cover the median nerve.

Abstract OBJECTIVE: Endoscopic release of carpal tunnel syndrome is still under debate. The main advantages of the technique are considered to be minor postoperative pain and a more rapid postoperative recovery. Disadvantages are thought to be the impossibility of a direct median nerve neurolysis and a higher surgical complication rate, including injury to the median nerve. METHODS: The results of 411 consecutive endoscopic carpal tunnel procedures performed between March 1995 and September 2004 are presented. All patients were prospectively followed. RESULTS: In the present series, a success rate of 98.05% was observed. There was no permanent morbidity and, in particular, there was no injury of the median nerve. In four (0.97%) patients, the preoperative symptoms did not improve. In two (0.49%) of these patients, an incomplete release of the carpal ligament occurred. In another four patients (0.97%), a switch to open surgery was required. CONCLUSION: The present data prove that the endoscopic technique is a safe and reliable technique for carpal tunnel surgery. The data do not support the current discussion of a higher risk of median nerve injury with endoscopic carpal tunnel surgery. Thus, for our group, the endoscopic technique represents the therapy of choice for the primary idiopathic carpal tunnel syndrome.

Introduction. Carpal tunnel syndrome (CTS) is caused by the compression of the median nerves in the wrist. Patients have pain and numbness in the hands. According to the records of Songklanagarind Hospital from 2015 to 2018, of 800 patients, 196 or 24.5% were treated with surgery. The novel tool of minimally invasive surgery for carpal tunnel syndrome (MIS-CTS) was developed to improve effectiveness and safety. Purpose. This study was performed to the effectiveness of visualization during surgery and the complete release of the transverse carpal ligament (TCL) and also the safety of using the MIS-CTS kits. Methods. Twenty fresh cadaveric forearms had surgery. Surgical techniques were (1) incision 15–18 mm at palmar hand; (2) the scissors and the navigator were inserted to create working space underneath the palmar aponeurosis; (3) the visual enhancer was inserted. The visual enhancer improves the visual field by shielding the soft tissue around the operative field; (4) the TCL was cut at the distal TCL by surgery scalpel, and then a flexible freer was used to detach the fibrous tissue from the median nerve and the TCL; and (5) the TCL cutting blade was pushed straight to cut the TCL completely from distal to proximal. TCL length was observed until the complete release. The median nerve and the recurrent branch of the median nerve were observed. Results. All TCL were cut completely. All median nerves, recurrent branches of the median nerve, and superficial palmar arches could be observed during the operation, and none were injured. This technique showed effectiveness and safety for minimally invasive carpal tunnel surgery. Conclusions. The study found that the new device, MIS-CTS kits, along with this technique is effective for CTS release in terms of minimally invasive open carpal tunnel surgery.

Persistent median artery (PMA) thrombosis is a rare cause of carpal tunnel syndrome (CTS) with only a few cases reported in the literature. The bifid median nerve (BMN) is often associated with PMA and may be a factor in the development of CTS. There is a paucity of information in the literature on the management options for CTS secondary to PMA thrombosis. This paper presents two cases of CTS with associated PMA thrombosis and BMN and offers a discussion on diagnostic and management options.

Carpal tunnel syndrome is the most common root canal pathology. The surgical treatment corresponds to a release of the median nerve by incision of the anterior annular ligament of the carpus by open surgical treatment or endoscopy. Knowledge of the normal anatomy and anatomical variations of the median nerve at the wrist is fundamental to avoiding complications in median nerve release in the treatment of carpal tunnel syndrome. Through this work we will show the interest of knowledge of the anatomy of the median nerve as well as its anatomical variations in order to derive the main clinical applications and to avoid the risks associated with open or endoscopic surgery in the treatment of carpal tunnel syndrome.
