ABSTRACTWe present a case of carpal tunnel syndrome (CTS) due to compression of the median nerve within the carpal tunnel, caused by cysticercosis. Nerve conduction studies revealed severe CTS. Magnetic resonance imaging suggested an inflammatory mass compressing the median nerve in carpal tunnel. The histological diagnosis was consistent with cysticercosis. The case resolved with conservative treatment. Such solitary presentation of entrapment median neuropathy as CTS caused by cysticercosis is extremely rare. To our knowledge, this is the only case of its kind reported in literature till date.

Tunnel Syndrome

We present a case report of a patient diagnosed with Holt-Oram syndrome (HOS) presenting with clinical and electrophysiologically confirmed carpal tunnel syndrome. Pre-operative Magnetic resonance imaging revealed an abnormal course of the median nerve; as such an atypical incision and approach were carried out to decompress the nerve to excellent post operative clinical effect. To our knowledge this is the first description of abnormal nervous course in a patient with HOS leading to peripheral entrapment. A literature surrounding the important aspects of HOS to the orthopaedic surgeon is presented concomitantly.

Tunnel Syndrome

Background:Carpal tunnel syndrome(CTS) is the most common form of entrapment neuropathies,caused by compression of the median nerve in the carpal tunnel at the wrist. But there is no gold standard technique for diagnosing CTS. Electrodiagnostic studies (EDS) are generally used but have some limitations. Recent years, magnetic resonance imaging(MRI) and ultrasonography(US) have facilitated the diagnosis of CTS. The median nerve cross section area(CSA) measured by US or MRI has been found to be associated with CTS[1]][2].CTS is usually idiopatic but it can be seen more in some disease. Psoriatic arthritis(PsA) occurs in up to 30% of people with psoriasis and can have serious debilitating effects on the peripheral joints, spine, tendon insertions, and fingers[3]. Because of arthritis, steroid use and flexor tenosynovitis play an important role in the pathogenesis of CTS, we think that CTS can be seen more in PsA patients.Objectives:We aimed to investigate the CTS in PsA patients with EDS, US and MRI than compare them with healthy controls.Methods:68 people, including 39 PsA (according to CASPAR criteria) and 28 healthy volunteers were included in study within 1 year. EDS, US and MRI were performed within maximum 2 weeks, and measurements were made by different doctors who were blind to other measurments. EDS was started with median and ulnar nerve motor conduction study than continued with sensory conduction studies. CTS diagnose was made according to the routine laboratory standards. The CSA measurement was made from the inner border of the hyperechoic ring around median nerve by using continuous tracing method at psiform bone level. US examinations were performed with a high frequency linear transducer (4-14 MHz), MRI examinations were performed on a 3-T imaging system. The statistical analyses were performed with Statistical Package for the Social Science Program Version 22. Descriptive statistics, T tests, chi-square test, Pearson correlation test were used.Results:No statifically significant difference was found between the groups for demographic characteristics. 12 (30.76%) of 39 PsA patients had CTS, whereas CTS was not detected in the control group(p= 0.001). US and MRI show larger CSA in PsA patients compared to the healthy control group(9,49 ± 3,00 mm2 vs 8,30 ±1,73mm2 p=0,005, 11,24 ± 3,41mm2 vs 9,35 ± 1,81mm2 p<0,001); in patients with CTS compared to others(11,63 mm2 ± 3,25 vs 8,60 ± 2,26mm2 p=0,002, 13,37 ± 3,37 mm2 vs 9,90 ± 1,58mm2 p<0,001) and in PsA patients which have CTS compared to PsA patients with normal EDS(11,63 ± 3,25 mm2 vs 8,87 ± 2,64 mm2 p=0,001, 13,37 ± 3,37 mm2 vs 10,52 ±3,15 mm2 p=0,003). When the CSA compared PsA patients which have normal EDS and healthy volunteers; US (8,87 ± 2,64 vs 8,30 ±1,73 p=0,180) and MRI (10,52 ±3,15 vs 9,35 ± 1,81 p=0,026) show larger CSA in PsA patients. But differance isn’t statistically significant for US measurments. The Pearson correlation coefficient between MRI and US measurements of the CSA was 0.85 (P<0,001).Conclusion:CTS is more common in patients with PsA. The relationship between CTS diagnosed by EDS and CSA measured by US or MRI was observed in both PsA patients and all participants. Diagnosis can be supported by US or MRI in patients who can not undergo EDS or who do not accept EDS. For PsA patients, cut off values obtained from normal people should not be used. The limitations of our study were that our CTS population was small and most of them was mild. We think that this study will be the precursor of CTS studies in PsA patients.References:[1]M. S.
