Compression Syndromes

In nerve compression syndromes restricted nerve sliding may lead to increased strain, possibly contributing to symptoms. Ultrasound was used to examine longitudinal median nerve sliding in 17 carpal tunnel syndrome patients and 19 controls during metacarpophalangeal joint movement. Longitudinal movement in the forearm averaged 2.62 mm in controls and was not significantly reduced in carpal tunnel syndrome (CTS) patients (mean=2.20 mm). In contrast, CTS patients had a 40% reduction in transverse nerve movement at the wrist on the most, compared to least, affected side and nerve areas were enlarged by 34%. Normal longitudinal sliding in the patients indicates that nerve strain is not increased and will not contribute to symptoms.

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.

Tunnel Syndrome

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.

Eleven wrists in eight patients with carpal tunnel syndrome were investigated by electrophysiological studies and magnetic resonance imaging (M.R.I.). The operative findings in ten wrists correlated with the M.R.I. evidence of synovial disease, carpal tunnel stenosis and median nerve compression.

Acute Carpal Tunnel Syndrome

A 23 year old female nurse developed acute sensory symptoms of median nerve compression. Early exploration revealed abnormal flexor superficialis indicis muscle as the compressing structure. Symptoms were relieved by freeing the muscle from the nerve.
