Vitamin D Deficiency Increases Risk of Carpal Tunnel Syndrome
Posted on August 30, 2019 by Korea Bizwire in Health & Wellness
SEOUL, Aug. 30 (Korea Bizwire) — A lack of vitamin D could increase the risk of carpal tunnel syndrome, which causes muscle weakness and numbness in the hands, a local study has revealed.
A research team at Seoul National University (SNU) Bundang Hospital analyzed the link between vitamin D and carpal tunnel syndrome among 135 female patients who visited the hospital between 2011 and 2014 and 135 women who visited the hospital for medical checkups.
The results showed that women with low levels of vitamin D were about 2.3 times more likely to develop carpal tunnel syndrome than normal groups.
In addition, the lower the vitamin level, the earlier in age the disease was reported.
In particular, the effects of deficiency were even greater in groups under the age of 50, and the risk of developing carpal tunnel syndrome was found to be about five times higher.
“A lack of vitamin D can cause upward adjustment of the receptor to compensate for the deficiency, which causes the proliferation of intravenous wall cells and connective tissue,” the team explained.
“That’s why the tunnel eventually becomes cramped and affects the incidence of carpal tunnel syndrome,” the team added.
Follow up research has also confirmed that supplementing vitamin D deficiency can help recover from carpal tunnel syndrome surgery, which broadens the wrist tunnel.
After checking vitamin levels prior to surgery, the team corrected the deficiency by treating patients who were deficient for six months.
As a result, the recovered group showed better results in the DASH test which evaluates postoperative results of carpal tunnel syndrome.
“Vitamin D is good for keeping your nerves healthy as well as your bones and muscles, so if it’s hard to supply enough food and sunlight, it’s better to take nutritional supplements,” said Prof. Gong Hyun-sik, a professor at SNU Bundang Hospital who led the research team.

24% had substantial relief to full relief of CTS (12 out of 50) and deferred CTS surgery
- Duration of symptoms was 1 month to 1 year (avg 6 months)
- Associated medical illness: hypothyroidism in 4 patients & diabetes in 9 patients
- 19 patients had no significant relief but for now they opted for conservative management (inj corticosteroid with night splints in 11 patients & only night splints in 8 patients)
- 8 patients ultimately underwent surgery to get relief from symptoms
In order to evaluate the effect of vitamin D3 we have evaluated around 50 patients in whom vitamin D deficiency was found & were suffering from CTS. They were all given deep intramuscular 6 lakhs unit of vitamin D. Out of this 12 patients had a substantial relief to full relief in whom surgery was deffered. The idea of writing this paper was a further study is warranted to prove its larger role in many compressive neuropathies & metabolic neuropathies if it can lead to clinical improvement in patients can save some of them from surgery

CTS may be classified into three stages:
- Mild: less than 1 year duration with absent weakness & atrophy with normal two point discrimination & EmG & NCV
- Moderate: duration may be less than or more than 1 year. Minimal presence of weakness & atrophy. Possible abnormality in two point discrimination examination. No to mild denervation in EMG test. No to mild decrease in velocity in NCV testing.
- Severe: duration is more than 1 year. Marked presence of weakness & atrophy. Marked abnormality in two point discrimation on examination.
During 1st author’s yearly regular health check-up a deficiency of vitamin D was diagnosed. His level was 7 (normal reference range 30 to 100). So 1st author took an injection of 6 lakh unit of vitamin D3 (cholecalciferol) deep intramuscular. To author’s surprise the tingling & numbness disappeared suddenly. Till now 1.5 year has been passed & he is still asymptomatic.

Measurements were made at the time of Carpal Tunnel Surgery
Studies suggest that low vitamin D levels are associated with carpal tunnel syndrome. We aimed to evaluate whether level of vitamin D receptor expression in the endothelial cells of the subsynovial connective tissue is associated with clinical features of carpal tunnel syndrome. We obtained the subsynovial connective tissue from 52 women with carpal tunnel syndrome during surgery and performed immunohistochemical analysis of vitamin D receptors in the endothelial cells of the subsynovial connective tissue. We explored correlation of vitamin D receptor expression with clinical features of carpal tunnel syndrome, such as age, symptom duration, symptom severity and electrophysiological severity. Diverse range of vitamin D receptor expression was observed. Vitamin D receptor expression was independently associated with distal motor latency.
This suggests that vitamin D receptor expression may be associated with disease progression, as prolonged distal motor latency reflects severity of the disease. Further studies are necessary to explore the role of vitamin D and vitamin D receptors in patients with carpal tunnel syndrome.

Carpal tunnel syndrome (CTS) and vitamin D deficiency are two discrete common clinical pictures that can cause chronic pain. In this study, we aimed to evaluate the association of 25 (OH) D deficiency with electrophysiological findings and severity of pain in patients with mild CTS.
The consecutive patients admitted to our laboratory with the symptoms of CTS between May 2016 and August 2016 were enrolled in this study. According to their electrophysiological examination results, only the patients with normal conduction results and ones with mild grade CTS were included. Demographic data, the results of the electrophysiological studies, vitamin D levels (our laboratory normal is > 20 ng / mL), duration of pain and pain intensity due to CTS which was assessed with visual analog scale were collected.
Totally, 76 patients (36 patients with mild CTS and 40 without CTS) were included. In the mild CTS patients, vitamin D levels were significantly lower than those electrophysiologically normal patients (p = 0.003). The relationship between gender, duration of pain and vitamin D levels were evaluated in the normal and mild CTS group. There was no significant relationship between the pain and vitamin D levels in the normal group, while vitamin D level was significantly lower in the mild CTS group (p = 0.730 and p = 0.002; respectively).
Vitamin D deficiency increases the pain intensity in patients with CTS. Treatment of vitamin D deficiency in these patients may play a role in pain relief. Further studies involving analyses of post-Vitamin D replacement therapy are warranted to confirm the association between vitamin D deficiency and pain due to CTS.

Vitamin D deficiencies are associated with a variety of chronic diseases. The goal of the present study was to investigate the relationship between vitamin D levels and carpal tunnel syndrome (CTS).
This study included 90 patients with mild to moderate CTS and assessed their routine serum 25-hydroxyvitamin D levels. Additionally, the pain level of each subject was evaluated using the Visual Analogue Scale and the Douleur Neuropathique 4 Questionnaire (DN4).
The severity levels of CTS were at a 75% mild level in the vitamin D deficiency group and a 47.1% mild level in the vitamin D normal group, with a significant difference between groups (p = 0.008). Correlation analyses revealed positive correlations between body mass index and DN4 scores (r = 0.499, p = 0.025) and between vitamin D levels and CTS severity (r = 0.364, p = 0.004) in the vitamin D deficiency group.
The present findings demonstrated that CTS may be triggered by vitamin D deficiency, and that the severity of CTS was correlated with vitamin D levels in the deficiency group. Additionally, there was a correlation between weight gain and neuropathic pain intensity in CTS patients with vitamin D deficiency. The present findings indicate that vitamin D levels should be assessed in CTS patients.

The aim of this study was to evaluate the relationship between 25-hydroxyvitamin D (25(OH)D) levels and carpal tunnel syndrome (CTS). 25(OH)D levels were checked in 108 consecutive patients with CTS symptoms and 52 healthy controls. All patients underwent nerve conduction studies and completed Boston Carpal Tunnel Questionnaire (BQ) symptom severity and functional status scales to quantify symptom severity, pain status and functional status. There were 57 patients with electrophysiological confirmed CTS (EP+ group) and 51 electrophysiological negative symptomatic patients (EP− group). 25(OH) D deficiency (25(OH)D < 20 ng/ml) was found in 96.1 % of EP− group, in 94.7 % of EP+ group and in 73.8 % of control group. 25(0H) D level was found significantly lower both in EP+ and EP− groups compared to control group (p = 0.006, p < 0.001, respectively). Although mean vitamin D level in EP− group was lower than EP+ group, statistically difference was not significant between EP+ and EP− groups (p = 0.182). BQ symptom severity and functional status scores and BQ pain sum score were not significantly different between EP+ and EP− groups. We found no correlation with 25(OH) D level for BQ symptom severity, functional status and pain sum scores. 25(OH) D deficiency is a common problem in patients with CTS symptoms. As evidenced by the present study, assessment of serum 25(OH)D is recommended in CTS patients even with electrophysiological negative results.

The Effect of Vitamin D Deficiency Correction on the Outcomes in Women After Carpal Tunnel Release
The Journal of Hand Surgery. https://doi.org/10.1016/j.jhsa.2019.03.008
Studies suggest that vitamin D supplementation improves myelination and recovery after nerve injuries. The purpose of this study was to evaluate whether correction of vitamin D level leads to better surgical outcomes in women with both carpal tunnel syndrome (CTS) and vitamin D deficiency.
We retrospectively reviewed 84 vitamin D–deficient women with CTS who underwent carpal tunnel release and then received daily vitamin D supplementation of 1,000 IU vitamin D for 6 months. We also reviewed 35 control patients who were vitamin D–nondeficient at baseline and thus did not receive the supplementation. At baseline and 6 months after surgery, we measured serum vitamin D levels, the Disabilities of the Arm, Shoulder, and Hand (DASH) score, motor conduction velocity, and grip and pinch strengths. We compared the outcomes of CTS related to vitamin D levels. We also correlated baseline and follow-up vitamin D levels with the assessed parameters.
At 6 months, 59 patients became vitamin D–nondeficient (≥ 20 ng/mL) and 25 were still vitamin D–deficient (< 20 ng/mL). Patients who became vitamin D–nondeficient had subtle but better DASH scores than patients who were still vitamin D–deficient or the control patients. Vitamin D levels at 6 months were found to have significant correlation with the DASH score at 6 months. Vitamin D levels at 6 months did not have significant correlation with motor conduction velocity or grip and pinch strengths.
Women with CTS and vitamin D deficiency showed subtle but better DASH scores after surgery when vitamin D deficiency was corrected by supplementation.

"Carpal Tunnel Symptoms absolutely can come from being Vitamin D deficient. It doesn't make a lot of sense, but I've seen it. I've seen all sorts of pain and problem of all sorts, even debilitating pain and problem, that goes away entirely or partially by getting back up to appropriate Vitamin D levels."
