| 1 | Fluctuation of visual analog scale pain scores and opioid consumption before and after total hip arthroplasty显示文摘BACKGROUND Patients who undergo orthopedic procedures are often given excess opioid medication.Understanding the relationship between pain and opioid consumption following total hip arthroplasty(THA)is key to creating safe and effective opioid prescribing guidelines.AIM To evaluate the association between the quantity of opioid consumption in relation to pain scores both pre-and postoperatively in patients undergoing primary THA.METHODS We retrospectively reviewed patients who underwent primary THA from November 2018-May 2019 and answered both the visual analog scale(VAS)pain and opioid medication questionnaires pre-and postoperatively.Both surveys were delivered daily for 7-days before surgery through the first 30 postoperative days.Survey results were divided into preoperative,postoperative days 1-7,postoperative days 8-14,and postoperative days 15-30 for analysis.Mean opioid pill consumption and VAS pain scores in each time period were determined and compared to patients’preoperative status using hierarchical Poisson and linear regressions,respectively.RESULTS There were 105 patients included.Mean VAS pain scores were the highest preoperatively 7.41±1.72.However,VAS pain scores significantly declined in each successive postoperative category compared to preoperative scores:postoperative day 1-7(5.07±1.79;P<0.001),postoperative day 8-14(3.60±1.64;P<0.001),and postoperative day 15-30(3.15±1.63;P<0.001).Mean opioid pill consumption preoperatively was 0.68±1.29 pills.Compared to preoperative opioid consumption,opioid use was significantly greater between postoperative days 1-7(1.51±1.58;P=0.001)and postoperative days 8-14(1.00±1.27;P=0.043).Opioid consumption declined below preoperative levels between postoperative days 15-30(0.35±0.72;P=0.160)which correlates with a VAS pain score of 3.15.CONCLUSION All patients experienced significant benefit and pain relief from having undergone THA.Average postoperative opioid consumption decreased below preoperative consumption between postoperative days 15-30,which was associated with a VAS pain score of 3.15.These results can be used to appropriately guide opioid prescribing practices and set patient expectations regarding pain management following THA. | Vivek Singh Alex Tang Thomas Bieganowski Utkarsh Anil William Macaulay Ran Schwarzkopf Roy I Davidovitch | 2022 | World Journal of Orthopedics2022，13，8： | 2 |
| 2 | Outcome of repair of chronic tear of the pectoralis major using corkscrew suture anchors by box suture sliding technique显示文摘AIM To assess the functional and clinical results of repair of chronic tears of pectoralis major using corkscrew and sliding suture technique. METHODS In this retrospective study, we reviewed the results of pectoralis major repair in 11 chronic cases(> 6 wk) done between September 2011 and December 2014 at our institute. In all cases repair was done by same surgeon using corkscrew suture anchors and box suture sliding technique. At 6 mo, after surgery magnetic resonance imaging was done to see the integrity of the repair. Functional evaluation was done using Penn and ASES scores. Pre and postoperative Isokinetic strength was measured.RESULTS Average follow-up was 48.27 ± 21.0 mo. The Wilcoxon signed rank test was used to evaluate the outcome scores. The average ASES score increased from an average of 54.63 ± 13.0 preoperatively to 95.09 ± 2.60 after surgery at their last follow-up. The average Penn score also increased from 5.72 ± 0.78, 2.81 ± 1.32 and 45.81 ± 1.72 to 9.36 ± 0.80, 8.27 ± 0.90 and 59 ± 1.34 for pain, satisfaction and function respectively. Follow up magnetic resonance imaging(MRI)(at 6 mo) showed continuity and the bulk of pectoralis major muscle in all cases. Average isokinetic strength deficiency in horizontal adduction at 60° was 13.63% ± 6.93% and at 120° was 10.18% ± 4.93% and in flexion at 60° was 10.72% ± 5.08% and at 120° was 6.63% + 3.74%. Results showed that both ASES and Penn score improved significantly(2 tailed P value = 0.0036).CONCLUSION We could conclude from this series that pectoralis major repair even in chronic cases using 5.5 mm corkscrew anchors give excellent functional and cosmetic results. In chronic cases the repairable length of the tendon is not available and sliding suture technique allows for fixation of worn out tendomuscular junction to bone without letting cutting through the muscle. | Deepak Joshi Jitesh Kumar Jain Deepak Chaudhary Utkarsh Singh Vineet Jain Ajay Lal | 2016 | World Journal of Orthopedics2016，7，10： | 0 |
| 3 | Hybrid plasmonic label-free multi-analyte refractive index sensor显示文摘We propose a label-free refractive index sensor based on hybrid plasmonic resonator which consists of silver split-ring resonator and photonic waveguide. The finite difference time domain evaluation of the design exhibit strong field confinement at the center of the ring and introduces tunable and sensitive notches in the transmission spectrum. The planar tunable architecture which performs well over the range of micro fluid detection, holds the promise of developing multi-analyte label-free biosensors and compactness towards a complete on-chip integrated sensing system. The performance of the proposed refractive index sensor is evaluated by placing different analytes such as saline water and ethanol at the center of the hybrid plasmonic ring which exhibits sensitivity of 847.50 nm·RIU-1 with a figure of merit of 563.25 RIU-1. | Kishore K.R.
