Arthroscopic lunate fossa resection arthroplasty for Kienböck's disease.

The aim of this study was to assess the outcome of arthroscopic lunate fossa resection arthroplasty for patients with Kienböck's disease, previously managed without operation, and a non-functional lunate fossa. For adult patients with relapse or exacerbation of pain from Kienböck's disease 2 years after the onset of symptoms, arthroscopic removal of lunate fossa cartilage was performed to reach bleeding bone, if the cartilage in the lunate fossa was non-functional and the scaphoid fossa was intact. Sixteen patients (mean age 35 years; range 27-56) were included. At a mean follow-up of 39 months (range 24-64), the preoperative mean visual analogue pain scale and QuickDASH score decreased from 7 (SD 2.2) and 50 (SD 16) to 1.4 (SD 1.6) and 13 (SD 9.6), respectively. A minor deterioration in mean radioscaphoid angle and carpal height ratio occurred. Arthroscopic lunate fossa resection arthroplasty is a viable option for selected patients with Kienböck's disease.Level of evidence: IV.

Outcomes of Arthroscopic Lunate Core Decompression Versus Radial Osteotomy in Treatment of Kienböck Disease.

PURPOSE: The purpose of the study was to evaluate the functional and radiographic outcomes of arthroscopic lunate decompression versus radial osteotomy in the treatment of Kienböck disease (KD). METHODS: In a prospective cohort design, we enrolled 82 patients with KD with Lichtman stages I to IIIb. Participants assigned themselves to groups by choosing either arthroscopic lunate core decompression and synovectomy (group A; n = 54) or radial osteotomy (group B; n = 28). For radial osteotomy, a distal radius volar approach was used and a shortening osteotomy (in negative and neutral ulnar variance) or lateral closing wedge osteotomy (in positive ulnar variance) was performed. Arthroscopic lunate core decompression was performed under direct visualization from the 3-4 portal using a shaver (through the 6R portal) and a cutting burr (through the trans-4 portal). The shortened Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, visual analog scale (VAS) score for pain, wrist passive flexion/extension, grip strength, and radiographic assessments (Lichtman classification, radioscaphoid angle, carpal height ratio) were recorded before surgery and at the final follow-up. RESULTS: Sixty-four patients were included in the final analysis (44 in group A and 20 in group B). The mean ages of participants were 33 ± 11 years in group A and 31 ± 8 years in group B. The mean follow-up periods were 44 ± 20 months in group A and 37 ± 23 months in group B. The QuickDASH score, VAS score, and passive wrist movements significantly improved in both groups. Grip strength showed a significant increase in group A only. The postoperative functional analysis between the 2 groups showed no significant difference, except for the wrist passive extension, which was higher in group A. Lichtman staging remained the same in 79.5% and 73.6% of patients in groups A and B, respectively. CONCLUSIONS: An arthroscopic lunate core decompression and wrist synovectomy has comparable midterm results to radial shortening osteotomy in the treatment of KD. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

The Effect of Acupressure on the Severity of Nausea, Vomiting, and Retching in Pregnant Women: A Randomized Controlled Trial.

INTRODUCTION: Nausea and vomiting are common problems during pregnancy. Previous studies have shown that stimulation at Neiguan (PC6) acupoint can be effective in controlling pregnancy-induced nausea and vomiting. However, more evidence is required for approving this method on controlling pregnancy-induced nausea and vomiting. The aim of this study was to determine the efficacy of PC6 acupoint pressure stimulation on the severity of nausea, vomiting, and retching in pregnant women. METHOD: This randomized, multi-center clinical trial was conducted on pregnant women referring to Health Centers and Ommolbanin Hospital in Mashhad, Iran, during December 2016 to September 2017. Women with first singleton pregnancy and below 12 weeks were included. Patients were randomly allocated into three groups of (1) PC6 pressure (4 times a day, for 10 min), (2) sham acupressure, and (3) medication with vitamin B6 and metoclopramide. Assessment of severity of nausea, vomiting, and retching was done based on the Rhodes Index on the first and fifth day (before and after the intervention). Pearson chi-square test, one-way ANOVA, Kruskal-Wallis, and Wilcoxon tests were used for statistical analysis using SPSS version 18. This clinical trial was registered at the Iranian Registry of Clinical Trials (IRCT) with the code IRCT201512187265N6. RESULTS: Ninety patients with a mean age of 26.40 ± 4.73 years were studied in 3 groups of 30. There was no significant difference between the 3 groups in terms of the severity outcomes before the intervention, while, after the intervention, the three groups were significantly different on the fifth day in terms of vomiting frequency, distress from retching, distress from vomiting, duration of nausea, distress from nausea, amount of vomiting, frequency of nausea, and frequency of retching (p < 0.001 for each outcome). According to the linear regression analysis, the correlation between occupation with vomiting frequency (beta coefficient = 0.252) and nausea severity (beta coefficient = -0.213) was statistically significant. CONCLUSION: It seems that PC6 acupoint pressure can reduce the severity of nausea, vomiting, and retching in pregnant women.

Menopause-related symptoms: traditional Chinese medicine vs hormone therapy.

OBJECTIVE: To compare the therapeutic effect of Chinese herbal medicine (CHM), acupuncture, and hormone therapy on menopause- related symptoms of peri- and postmenopausal women. STUDY DESIGN: Fifty-seven Chinese women completed 2 months of treatment with either CHM (5 g twice daily, n = 22), acupuncture plus CHM (Kun Bao Wan) 5 g twice daily plus sessions of acupuncture, n = 20), or hormone therapy (n = 15). MAIN OUTCOME MEASURES: Kupperman index score, levels of follicle-stimulating hormone (FSH) and estradiol, and the number of symptoms before and after treatment were the main outcome measures. RESULTS: CHM, acupuncture plus CHM, and hormone therapy significantly decreased Kupperman score (P < .001 in each group) and number of symptoms (P < .05). The mean difference in Kupperman score between baseline and 2 months among the three groups was significantly varied (P = .02). The difference was only between acupuncture plus CHM and CHM with significantly better results by acupuncture plus CHM. Acupuncture plus CHM, as well as hormone therapy, significantly reduced the level of FSH (P < .05), but CHM alone didn't cause any significant decrease in FSH levels (P > .05). The mean difference in the level of FSH between baseline and 2 months among the three groups was significantly different (P = .02). This difference was only between CHM and hormone therapy with significantly better results by hormone therapy. The three treatments didn't make any significant increase in the level of E2 (P > .05). CONCLUSION: application of the combination of Chinese herbal medicine and acupuncture proved as effective as hormone therapy in the treatment of menopause-related symptoms, and it achieved better outcomes than herbal medicine alone.
