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.

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.

Background: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, which results from median nerve compression. A lot of nonsurgical modalities are available for the management of mild to moderate situations. Local Hyalase hydrodissection (HD) of the entrapped median nerve could offer a desirable sustained symptom alleviation. Objectives: To evaluate the clinical efficacy of Hyalase/saline solution carpal tunnel HD on pain, functional status, and nerve conduction in patients with CTS. Study Design: A randomized, double-blinded trial. Setting: Anesthesia, pain, and rheumatology clinics in a university hospital. Methods: Patients: 60 patients with CTS (> 6 months’ duration). Intervention: patients were allocated equally into either group 1 (HD with Hyalase + 10 mL saline solution injection), or group 2 (HD with 10 mL saline solution only). Measurements: assessment of pain using Visual Analog Scale (VAS), functional disability (FD) score, and nerve conduction studies before injection, and over 6 months after injection. Nerve conduction parameters before injection and postinjection by the end of 3 and 6 months were evaluated as well. Results: Statistically significant lower postinjection values of VAS (1 ± 1.8, 2 ± 1.1, 2 ± 1.2, 2 ± 1.1) in group 1 versus (2 ± 1.2, 3 ± 1.7, 4 ± 1.5, 5 ± 2.6) in group 2 by the end of the first week, and the first, third, and sixth months, and significantly lower FD scores (15.3 ± 1.2, 13 ± 1.3, 10.2 ± 1.3, 10.2 ± 1.3) in group 1 versus (17.5 ± 1.8, 16.6 ± 2.8, 19.4 ± 3.2, 21.2 ± 2.5) in group 2 during the same time intervals. Nerve conduction study parameters have shown significantly higher velocity and lower latency in the Hyalase group than in the saline solution group by the 3 and 6 month follow-up. Limitation: We suggest a longer period could be reasonable. Conclusions: Carpal tunnel HD with Hyalase with saline solution is considered as an efficient technique offering a rapid onset of pain relief and functional improvements, and better median nerve conduction in patients with CTS over 6 months follow-up duration. Key words: Carpal tunnel syndrome, Hyalase, median nerve hydrodissection

Tunnel Syndrome

Carpal tunnel syndrome is conventionally treated by open and endoscopic release surgeries in which transecting the transverse carpal ligament (TCL) relieves mechanical insults around the median nerve. The TCL release surgeries yield an increase in the tunnel cross-sectional area particularly within the volar aspect of the tunnel, the arch area, where the median nerve is located. As a result of increased arch area, post-operative follow-up studies using MRI confirmed a significant volar migration of the median nerve [1]. However, transecting the TCL compromises critical biomechanical roles of the carpal tunnel [2], and therefore, it is imperative to investigate an alternative method for treating carpal tunnel syndrome patients while preserving the TCL. Li et al. suggested that increasing the TCL length and narrowing the carpal arch width (CAW) as potential alternatives for increasing the arch area [3]. However, the data from their application of palmarly directed forces to the TCL from inside of the tunnel showed that the TCL length remained relatively constant while the carpal bones were mobilized to increase the arch area [3]. The purpose of this study was to investigate the relationship between CAW narrowing and the TCL-formed arch area by experimental and geometrical modeling.

We prospectively studied 266 hands in 133 patients with carpal tunnel syndrome (CTS) in order to evaluate: the incidence of bilateral CTS symptoms; correlation between severity, duration of symptoms and bilateral occurrence of CTS; agreement of clinical and neurophysiological findings; and the neurophysiological findings in asymptomatic hands in unilateral CTS, The incidence of bilateral clinical CTS in our population was 87%. Neurophysiological impairment of median nerve was observed in about half of the asymptomatic hands. Follow-up of patients with unilateral CTS showed that contralateral symptoms developed in most cases. We found a significant positive correlation of bilateral CTS with the duration of symptoms, whereas there was no correlation with the severity of symptoms. Our data suggest that bilateral impairment of median nerve is the rule in patients with CTS and probably it has been underestimated in previous studies.

Double Blinded

Ultrasound-guided perineural dextrose injection (PDI) has been reported effective for carpal tunnel syndrome (CTS). Higher volume of injectate may reduce adhesion of median nerve from other tissues, but volume-dependent effects of PDI in CTS remain unknown. We aimed to investigate whether PDI with different injectate volumes had different effects for CTS participants. In this randomized, double-blinded, three-arm trial, 63 wrists diagnosed with CTS were randomized into three groups that received ultrasound-guided PDI with either 1, 2 or 4 ml of 5% dextrose water. All participants finished this study. Primary outcome as visual analog scale (VAS) and secondary outcomes including Boston Carpal Tunnel Questionnaire (BCTQ), Disability of the Arm, Shoulder and Hand score (QuickDASH), electrophysiological studies and cross-sectional area (CSA) of the median nerve at carpal tunnel inlet were assessed before and after PDI at the 1st, 4th, 12th and 24th weeks. For within-group analysis, all three groups (21 participants, each) revealed significant improvement from baseline in VAS, BCTQ and QuickDASH at the 1st, 4th, 12th and 24th weeks. For between-group analysis, 4 ml-group yielded better VAS reduction at the 4th and 12th weeks as well as improvement of BCTQ and QuickDASH at the 1st, 4th, and 12th weeks, compared to other groups. No significant between-group differences were observed in electrophysiological studies or median nerve CSA at any follow-up time points. There were no severe complications in this trial, and transient minor adverse effects occurred equally in the three groups. In conclusion, ultrasound-guided PDI with 4 ml of 5% dextrose provided better efficacy than with 1 and 2 ml based on symptom relief and functional improvement for CTS at the 1st, 4th, and 12th week post-injection, with no reports of severe adverse effects. There was no significant difference between the three groups at the 24th-week post-injection follow-up.Clinical Trial Registration:www.ClinicalTrials.gov, identifier NCT03598322.

And Function

A prospective study of electrophysiological examination and the Boston self-administered questionnaire (BQ) was carried out in patients with surgically-treated carpal tunnel syndrome. There were 104 hands in 93 patients (13 men and 80 women, mean age 56 years). The BQ was used to assess the severity of symptoms and function, and nerve conduction studies were done before surgical release by short incision at the palm, and at follow-ups 1 and 6 months after surgery. The BQ severity score improved or became normal in 98% of hands. The mean BQ scores and distal sensory and motor conduction velocities in the median nerve showed significant improvement at the 1 month follow-up. Further significant improvement was found at 6 months. There was no relationship between the improvements in BQ scores and the distal conduction in the median nerve. The degree of improvement in sensory and motor distal conduction velocities could be forecast from presurgical values, whereas the degree of improvement in the symptoms and the functional status after release could not be predicted from the presurgical BQ scores.

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.
