Canal Syndrome

Perioperative Guyon’s canal and carpal canal pressure in one-forearm portal endoscopic carpal tunnel release surgery were measured in resting position and during active power gripping in 66 hands. This was done using the continuous infusion technique with a local anaesthetic and without pneumatic tourniquet. Immediate mean postoperative Guyon’s canal and carpal canal pressure decreased in both measurements. During active power gripping, postoperative Guyon’s canal pressure was less than 40 mmHg in 61 hands, however, this increased to over 40 mmHg in five hands. In these five hands, Guyon’s canal syndrome did not develop. Guyon’s canal and carpal canal pressures were only correlated during postoperative active power gripping. It remains unclear whether immediate postoperative Guyon’s canal pressure correlates with higher pressures a few days later as reported in cases of transient postoperative Guyon’s canal syndrome.

Ulnar Tunnel

We measured pressure changes in Guyon's canal and the carpal tunnel before and after endoscopic (11 cases) and open (10) carpal tunnel release. We found that release of the flexor retinaculum by endoscopic and open techniques measurably decreased pressure in both the carpal tunnel and Guyon's canal. This study provides an explanation for relief of ulnar tunnel syndrome symptoms following carpal tunnel release and may indicate that carpal tunnel release alone may be sufficient to provide symptomatic relief for most patients with carpal and ulnar tunnel syndromes.

Background: Resolution of symptoms including pain, numbness, and tingling outside of the median nerve distribution has been shown to occur following carpal tunnel release. We hypothesized that a similar effect would be found after combined release of the ulnar nerve at the elbow with simultaneous release of the median nerve at the carpal tunnel. Methods: 20 patients with combined cubital and carpal tunnel syndrome were prospectively enrolled. The upper extremity was divided into six zones and the location of pain, numbness, tingling, or strange sensations was recorded pre-operatively. Two-point discrimination, Semmes-Weinstein monofilament testing, and validated questionnaires were collected pre-operatively and at six-week follow-up. Results: Probability of resolution was greater in the median nerve distribution than the ulnar nerve for numbness (71% vs. 43%), tingling (86% vs. 75%). Seventy percent of the cohort reported at least one extra-anatomic symptom pre-operatively, and greater than 80% of these resolved at early follow-up. There was a decrease in pain as measured by validated questionnaires. Conclusion: This study documents resolution of symptoms in both extra-ulnar and extra-median distributions after combined cubital and carpal tunnel release. Pre-operative patient counseling may therefore include the likelihood of symptomatic improvement in a non-expected nerve distribution after this procedure, assuming no other concomitant pathology which may cause persistent symptoms. Future studies could be directed at correlating pre-operative disease severity with probability of symptom resolution using a larger population.
