In a patient with severe, recurrent bilateral carpal tunnel syndrome secondary to mucolipidosis, the ‘turnover’ palmaris brevis flap was used in conjunction with internal neurolysis. The procedure was effective in alleviating symptoms of recurrent carpal tunnel compression in both hands.

Background: Many patients treated for ulnar nerve compression at the elbow (UNE) are concomitantly treated for carpal tunnel syndrome (CTS). We sought to investigate the association between the conditions. Methods: The Statewide Planning and Research Cooperative System (SPARCS) database was used to determine the number of patients with UNE concomitantly treated for CTS in New York State from 2003 to 2014. We then retrospectively reviewed each patient who received surgical treatment for UNE (n = 222 patients) or CTS (n = 1063 patients) at our tertiary care institution in 2014 and 2015 to assess concomitant treatment. Results: In the SPARCS database, the percentage of patients surgically treated for concomitant UNE and CTS steadily increased from 23% in 2003 to 45% in 2014. At our institution, 50 of 222 patients (23%) surgically treated for UNE underwent concomitant carpal tunnel releases. For concomitantly treated patients, 94% had examinations consistent with UNE and CTS, 87% of patients had median nerve compression on electrodiagnostic tests, and 72% of patients had UNE on electrodiagnostic tests. Conclusions: Most patients concomitantly treated for UNE and CTS have objective findings of both conditions. At least one-fourth of patients indicated for operative ulnar nerve release also require a carpal tunnel release—far beyond the prevalence of CTS in the general population. A diagnosis of UNE merits a comprehensive workup by the treating surgeon and a high suspicion for concomitant median nerve compression.

Tunnel Syndrome

A case is presented of a bifid median nerve whose longest portion had a normal course while the other portion passed through a hole in the FDS tendon of the middle finger, at its musculotendinous junction. This caused nerve compression during muscle contraction, producing pain and dysaesthesia in the middle finger suggesting carpal tunnel syndrome.

Tunnel Syndrome

Some cases of carpal tunnel syndrome in macrodactyly patients have been reported. We performed endoscopic carpal canal release on two unilateral macrodactyly patients suffering from bilateral carpal tunnel syndrome. We measured carpal canal pressure before performing endoscopic surgery using the Universal Subcutaneous Endoscope system to confirm median nerve compression. We diagnosed median nerve compression in each patient due to the high preoperative carpal canal pressure. Carpal canal pressure immediately decreased to within normal range following release of both the flexor retinaculum and the distal holdfast fibres of the flexor retinaculum. One patient recovered to within normal in terms of sensory disturbances and abductor pollicis brevis muscle strength. The other patient showed improvement in terms of sensory disturbance, however, muscle power did not recover because this patient had suffered from carpal tunnel syndrome for ten years. Endoscopic carpal canal release and decompression surgery was effective for carpal tunnel syndrome in both macrodactyly patients.

Abstract There are conflicting hypotheses regarding the initial pathogenesis of carpal tunnel syndrome (CTS). One hypothesis characterizes it as inflammation of the median nerve caused by compression, while another hypothesis characterizes CTS as non-inflammatory fibrosis of the subsynovial connective tissue (SSCT). This study aimed to investigate the differences in the ultrasonography parameters before and after a steroid injection, which is effective for CTS, to elucidate the initial pathogenesis of CTS and the mechanisms of action of the injected steroid. Fourteen hands from 14 healthy participants and 24 hands from 24 participants with mild CTS were examined. Dynamic movement and morphology of the median nerve before and after steroid injection were measured. There was no significant difference in the normalized maximal distance of the median nerve, which reflects the degree of fibrosis in the SSCT indirectly, during finger and wrist movements before and after the injection among patients with CTS (p > 0.05). Among the parameters that indirectly reflects the degree of median nerve compression, such as normalized maximal change in the aspect ratio of the minimum-enclosing rectangle (MER), maximal change in the median nerve perimeter, and maximal value of the median nerve cross-sectional area (CSA), statistically significant differences were not observed between values of the normalized maximal change in the aspect ratio of the MER and maximal change in the median nerve perimeter, during finger and wrist movements recorded before and after the injection in patients with CTS (p > 0.05). However, multivariate logistic regression analysis revealed that the change in the normalized maximal value of the median nerve CSA, according to finger and wrist movement was correlated with the administration of the steroid injection (p < 0.05). In conclusion, compared to that noted before steroid injection, the median nerve CSA noted during finger and wrist movements changed significantly after injection in patients with mild CTS. Given the improvement in median nerve swelling after steroid injection, but no improvement in the movement of the median nerve during finger and wrist movements, median nerve swelling due to compression (rather than fibrosis of the SSCT may be the initial pathogenesis of early-stage (mild) CTS, and the fibrous changes around the median nerves (SSCT) may be indicative of secondary pathology after median nerve compression. Further studies are required to validate the findings of our study and confirm the pathogenesis of CTS.
