The Effect of Vitamin D Deficiency Correction on the Outcomes in Women After Carpal Tunnel Release.

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: Women with CTS and vitamin D deficiency showed subtle but better DASH scores after surgery when vitamin D deficiency was corrected by supplementation. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Use of a decision aid did not decrease decisional conflict in patients with carpal tunnel syndrome.

BACKGROUND: Although a model for shared decision-making is important for patient-centered care, decisional conflict can emerge when patients participate in the decision-making. A decision aid is proposed to provide information and to involve patients more comfortably in the decision-making process. We aimed to determine whether a decision aid helps patients with carpal tunnel syndrome (CTS) experience less decisional conflict regarding their decision-making for surgery. METHODS: Eighty patients with CTS were randomized into two groups. The test group was given a decision aid in addition to regular information and the control group regular information only. The decision aid consisted of a 6-min videoclip that explains diagnosis and information regarding surgery for CTS with other treatment options. We evaluated patients' decisional conflict regarding surgery, knowledge about CTS, and symptom severity as measured by the Disabilities of Arm, Shoulder, and Hand (DASH) Questionnaire. RESULTS: There was no difference in the decisional conflict scale (DCS) between both groups (p = 0.76). The test group had significantly better knowledge than the control group (p = 0.04). There was no correlation between the knowledge score and the DCS (p = 0.76). However, less severe symptoms were correlated with greater decisional conflict (r = -0.29, p = 0.02). CONCLUSIONS: We found that a decision aid does not reduce decisional conflict in patients with CTS, although it can help them be better informed. This study suggests that although a decision-aid is effective for patient education, doctor-patient communication should be more emphasized for patients with less severe symptoms, as they can have greater decisional conflict.

Comparison Of Isokinetic Muscle Strength And Clinical Outcomebetween Isolated And Combined PCL Reconstruction.

The purposes of this study was to 1) compare the functional result and muscle strength between patients who underwent reconstruction by isolated posterior cruciate ligament (PCL) and combined PCLposeterolateral corner sling (PLCS) reconstruction. Nineteen (Group I: isolated PCL reconstruction) and 30 (Group II: combined PCL-PLCS reconstruction) were compared. The clinical results and isokinetic muscle strength were compared between groups. The clinical results were comparable between groups and posterior stability was not different between the two groups, either. The isokinetic strength test result was not significantly different between the two groups, although absolute values of the flexion strength in Group I was higher than those in Group II. The HQ ratio of the affected side in Group I was similar to that of the contralateral side. Isokinetic muscle strength, especially flexion, was not fully recovered as compared with the contralateral side in both groups, although clinical and stability results were improved. However, the isolated PCL reconstruction group that was managed with the accelerated rehabilitation protocol showed an HQ ratio similar to that of the contralateral side. Therefore, an earlier active strengthening program would be also necessary in PCL-PLCS reconstructed groups, and justification for prevention of early weight bearing in PCL-PLCS reconstruction should be re-evaluated because weight bearing is helpful for muscle strengthening.

Clinical Performance of the 1st American Academy of Orthopaedic Surgeons Clinical Guideline on Prevention of Symptomatic Pulmonary Embolism after Total Knee Arthroplasty in Korean Patients.

We sought to document the clinical performance of the 1st American Academy of Orthopaedic Surgeons (AAOS) guideline on the prevention of symptomatic pulmonary embolism (PE) after total knee arthroplasty (TKA) in Korean patients, in terms of the proportions of the each risk-stratified group, efficacy and safety. Consecutive 328 patients underwent TKA were preoperatively assessed for the risks of PE and bleeding and categorized into 4 groups: 1) standard risk, 2) high risk for PE, 3) high risk for bleeding, and 4) high risks both for PE and bleeding. One of three options was administered according to the groups (aspirin in group 1 or 4; enoxaparin and following aspirin in group 2; antithrombotic stocking in group 3). Incidences of symptomatic deep vein thrombosis (DVT) and PE, and major or minor bleeding complications were evaluated. Majority of the patients (86%) were assessed to be with standard risks both for PE and bleeding. No patient experienced symptomatic DVT or PE and major bleeding. Eleven percent of the patients discontinued chemoprophylaxis because of bleeding-related wound complication. In conclusion, the 1st AAOS guideline functions successfully in Korean patients undergoing TKA in terms of prevention of symptomatic DVT and PE while avoiding major bleeding complications.

Prediction of Mortality and Postoperative Complications using the Hip-Multidimensional Frailty Score in Elderly Patients with Hip Fracture.

High mortality and dependent living after hip fracture pose a significant public health concern. Retrospective study was conducted with 481 hip fracture patients (≥65 years of age) undergoing surgery from March 2009 to May 2014. The Hip-MFS was calculated by Comprehensive Geriatric Assessment (CGA). The primary outcome was the 6-month all-cause mortality rate. The secondary outcomes were 1-year all-cause mortality, postoperative complications and prolonged hospital stay, and institutionalization. Thirty-five patients (7.3%) died within 6 months after surgery (median [interquartile range], 2.9 [1.4-3.9] months). The fully adjusted hazard ratio per 1 point increase in Hip-MFS was 1.458 (95% confidence interval [CI]: 1.210-1.758) for 6-months mortality and odds ratio were 1.239 (95% CI: 1.115-1.377), 1.156 (95% CI: 1.031-1.296) for postoperative complications and prolonged total hospital stay, respectively. High-risk patients (Hip-MFS > 8) showed higher risk of 6-month mortality (hazard ratio: 3.545, 95% CI: 1.466-8.572) than low-risk patients after adjustment. Hip-MFS successfully predict 6-month mortality, postoperative complications and prolonged hospital stay in elderly hip fracture patients after surgery. Hip-MFS more precisely predict 6-month mortality than age or existing tools (P values of comparison of ROC curve: 0.002, 0.004, and 0.044 for the ASA classification, age and NHFS, respectively).
