We aimed to investigate whether there is an interaction between life-space assessment (LSA) and movement control during one-leg standing on bone strength on the non-fractured side in patients with hip fracture. Two-way analysis of variance (ANOVA) was applied for osteoporosis parameter to examine the interaction and main effects of LSA and movement control during one-leg standing. Two-way ANOVA revealed significant interaction and main effects of LSA and movement control during one-leg standing on bone mineral density (BMD) and Z-score. In parameters of hip structural analysis (HSA), the interaction and main effect of movement control during one-leg standing were detected only in cross-sectional area (CSA). The results of this study suggest that both high LSA and good movement control during one-leg standing are necessary to maintain or improve some parameters of bone strength, such as BMD (neck and total hip), Z-score (neck and total hip), and CSA.

Background: Plating of proximal phalangeal fracture is the commonly adopted fixation method. However, whether placing the implant at the dorsal or lateral aspect of the phalanx can yield a better clinical outcome is still under debate. Our study aims to compare the functional outcome of dorsal plating versus lateral plating in patients suffering from a proximal phalangeal fracture. Methods: A retrospective comparative study was performed comparing the clinical outcome of dorsal and lateral plating in proximal phalangeal fracture. Fourteen patients from our center with a total of 17 proximal phalangeal fractures (excluding the thumb) were included in this study. The total range of movement and range of movement of each finger joint together with grip strength were the main focuses of this study. Operative complications and the need for subsequent related operations were also analyzed. Results: Nine cases were treated by dorsal plating and eight cases adopted lateral plating. There was no significant difference in demographic data between the two groups with a mean follow-up period of 20.75 months. Lateral plating provided better total range of movement (dorsal plating (D): 203.9 ± 35.2 vs. lateral plating (L): 248.8 ± 23.7; p-value = 0.01) and percentage change in total range of movement (D: 79.41% ± 10.35, L: 94.47% ± 6.09; p-value < 0.01). There was less extension lag in lateral plating as evidenced by the sum of extension lag of the three finger joints being statistically significantly smaller (D: 32.8 ± 14.2 vs. L: 4.44 ± 6.2, p < 0.01). Less percentage decrease in grip strength compared with the contralateral normal hand was also noted in the lateral plating group (D: 68.17% ± 31.11 vs. L: 98.13% ± 10.88, p = 0.02). Conclusions: Based on this study, lateral plating provides better functional outcomes in terms of range of movement, extension lag, and grip strength than dorsal plating. Level of Evidence: Therapeutic, retrospective comparative study, Level III.

Introduction: As the number of annual total knee arthroplasty (TKA) procedures increases the number of revision surgeries will continue to increase. Several prior studies have identified various mechanisms of TKA failure and reported a number of reasons as the most common causes. The purpose of this review was to evaluate the causes of revision TKA at a single institution and to compare those reasons with previously published data in order to provide a current update on the topic. Methods: A retrospective review of all patients undergoing TKA revision by board-certified surgeons at a single institution between January 2, 2014 and October 16, 2020 was conducted. Statistical analysis was performed to identify trends among revision reasons and compare postoperative outcomes. Results: Of the 548 patients, 179 (32.7%) had an early revision and 369 (67.3%) had a late revision. The most common causes for early revision were infection (31.3%), loosening (27.4%), and instability (10.1%). The most common causes for late revision were loosening (29.5%), infection (22.2%), and polyethylene wear (20.3%). Postoperatively, there were no significant differences in OR time, length of stay, discharge status, 30-day readmission rates, or 30-day emergency department return rates between early and late revisions. Discussion: This study demonstrated the main causes for revision at a high-volume orthopedic joint replacement center. The most common reasons for revision were infection, loosening, instability, and polyethylene wear. This data in comparison to studies in the past suggests that the causes of revision are constantly evolving and need to be reassessed periodically in order to align focus on improvement.

Introduction: Periprosthetic joint infection after total knee arthroplasty (TKA) is a devastating complication and different risk factors, including hyperglycemia and increased glucose variability, have been suggested for this condition in previous literature. Our study aims to investigate the risk factors for postoperative hyperglycemia and glucose variability in patients undergoing unilateral primary TKA with continuous glucose monitoring (CGM) technology. Methods: Demographic factors, diabetic statuses, hemoglobin A1c (HbA1c) levels, and fructosamine levels of patients undergoing unilateral primary TKA were recorded preoperatively. These patients would either received 16 mg intravenous dexamethasone or no dexamethasone before their surgery as part of perioperative management. From the day of admission to postoperative day 4, CGM device monitored these patients’ blood glucose level, time of hyperglycemia, and glucose variability. Correlation and multivariate regression analysis were performed between the risk factors and the outcome measures, with multicollinearity between the predictor variables checked, to find out the most potent risk factors for postoperative hyperglycemia. Results: Eighty-three patients with primary unilateral TKA were analyzed. Diabetic, prediabetic, and nondiabetic patients were composed of 26.5%, 47.0%, and 26.5%, respectively. The average of HbA1c and fructosamine level was 6.0% and 249.3 mmol/L, respectively; 65.1% of the patients received 16 mg dexamethasone perioperatively. Multivariate regression analysis found that HbA1c, fructosamine, and dexamethasone injections are the significant risk factors for the percentage of time in hyperglycemia ( R2 = 0.374, p < 0.001) and average blood glucose level ( R2 = 0.493, p < 0.001), with HbA1c having the highest standardized coefficient, followed by fructosamine and dexamethasone injections. Although dexamethasone usage was significant in multivariate regression analysis on predicting glucose variability, the effect size of the model is very weak ( R2 = 0.05, p < 0.05). Conclusion: The most potent risk factor for hyperglycemic time and increased average blood glucose is HbA1c level, followed by fructosamine level and dexamethasone injections. No strong correlation was found between the factors in our study and patients’ glucose variability.
导言:全膝关节置换术(TKA)后假体周围关节感染是一种毁灭性的并发症，在以往的文献中，不同的危险因素，包括高血糖和葡萄糖变异性增加，被认为是这种情况的危险因素。我们的研究旨在通过持续血糖监测(CGM)技术探讨单侧原发性TKA患者术后高血糖和血糖变异性的危险因素。方法:术前记录单侧原发性TKA患者的人口学因素、糖尿病状态、糖化血红蛋白(HbA1c)水平、果糖胺水平。这些患者在手术前接受16毫克静脉注射地塞米松或不接受地塞米松作为围手术期管理的一部分。从入院当天到术后第4天，CGM装置监测患者的血糖水平、高血糖时间和血糖变异性。对危险因素与预后指标进行相关性分析和多元回归分析，并对预测变量进行多重共线性检验，找出术后高血糖最重要的危险因素。结果:对83例原发性单侧TKA患者进行分析。糖尿病、糖尿病前期和非糖尿病患者分别占26.5%、47.0%和26.5%。HbA1c平均值为6.0%，果糖胺平均值为249.3 mmol/L;65.1%的患者围手术期接受16 mg地塞米松治疗。多因素回归分析发现，HbA1c、果糖胺和地塞米松注射液是影响高血糖时间百分比(R2 = 0.374, p < 0.001)和平均血糖水平(R2 = 0.493, p < 0.001)的显著危险因素，其中HbA1c的标准化系数最高，其次是果糖胺和地塞米松注射液。虽然地塞米松使用在预测血糖变异性的多变量回归分析中具有显著性，但模型的效应量非常弱(R2 = 0.05, p < 0.05)。结论:HbA1c水平是高血糖时间和平均血糖升高的最重要危险因素，其次是果糖胺水平和地塞米松注射。在我们的研究中，没有发现这些因素与患者的血糖变异性有很强的相关性。

Background/Purpose: The purpose of this study was to determine the short-term minimal clinically important differences (MCIDs) in Knee injury and Osteoarthritis Outcome Score (KOOS) after total knee arthroplasty (TKA) using the anchor method. Methods: Scores for each KOOS subscale were calculated preoperatively and 3 and 6 months postoperatively to create receiver operating characteristic curves, and the MCIDs were calculated. Results: The KOOS MCIDs at 3 months after TKA were 6 for symptoms, 10 for pain, 6 for activities of daily living (ADL), 8 for sport/recreation, and 10 for quality of life (QOL). The KOOS MCIDs at 6 months after TKA were 9 for symptoms, 13 for pain, 10 for ADL, 9 for sport/recreation, and 16 for QOL. The areas under the curves were in the range of 0.8–0.9 at both 3 and 6 months after TKA. Conclusion: MCIDs by KOOS subscales were determined and were highly accurate.

Background: Most biomechanical studies in populations with low back pain have examined level gait or stationary tasks. This study investigates step negotiation in a subgroup of individuals with low back pain. Methods: Surface electromyography and kinetic data were collected in 22 subjects. Results: Vertical ground reaction force rise-time was slower in participants with low back pain when leading with the left leg and they had delayed muscle onsets of the right gluteus medius, left rectus abdominis with left stepping, right lumbar erector spinae with right stepping but earlier onset with left stepping. EMG activations were higher in the participants with low back pain in the right lumbar erector spinae, right gluteus medius, and left gluteus medius in both left and right steps. Conclusion: The results of this study show that the participants with low back pain have higher muscle activity levels, delayed muscle onsets, and slower weight acceptance.

This study aims at determining the prevalence of little finger brachymesophalangia (BMP-V) in the Chinese ethnic population. A retrospective study reviewing hand radiographs taken in United Christian Hospital from January 2011 to July 2016. Exclusion criteria included previous hand trauma, background history of genetic syndromes and non-Chinese ethnic origin. The radiographs were assessed with objective measurement using computer software and were defined BMP-V with the following criteria: (1) 5th MP length: 4th MP length <0.65 and (2) 5th MP length: 5th PP length <0.50. The radiographs would be included as BMP-V cases if they fulfil both criteria. A total of 563 hand radiographs in 394 patients (290 left hands and 273 right hands; 169 bilateral hands) were reviewed. The mean age (± standard deviation) was 51.3 ± 11.7 years (ranging from 25 to 69 years). Forty-four patients were identified to have BMP-V. The prevalence of BMP-V was found to be 11.2%. Clinodactyly with trapezoidal shape middle phalanx was found in 6.82% of the BMP-V cases. All subjects with bilateral hand radiographs showed symmetrical findings concerning the presence of BMP-V. This is the first study to report the prevalence of brachymesophalangia-V in the Chinese adult population. The prevalence of BMP-V in the Chinese adult population was found to be 11.2%. It is lower than Japanese group but higher than other ethnic groups documented in other studies.

Purpose: We investigated whether the anterior border of the tibia is parallel to the tibial axis, and which position of the anterior border should be used as a landmark of the tibial axis in total knee arthroplasty. Methods: Ninety-one patients prior to total knee arthroplasty were evaluated. Electrocardiogram electrodes were placed along the anterior border at 5 cm (A), 10 cm (B), and 15 cm (C) distal to the tibial tuberosity, and an anteroposterior X-ray image was taken. The angles of the AC, AB, and BC lines on the tibial bone axis line were measured. Results: The mean angles of the AC, AB, and BC lines to the tibial bone axis line were, respectively, 1.09, 2.22, and −0.02. The percentages within −3° to +3° were 86.8, 64.8, and 92.3, respectively. Conclusions: A line connecting a point 10–15 cm distal to the tibial tuberosity can serve as a reference line for total knee arthroplasty.
目的:我们研究胫骨前缘是否平行于胫骨轴，以及在全膝关节置换术中，前缘的哪个位置应该作为胫骨轴的标志。方法:对91例全膝关节置换术前患者进行回顾性分析。心电图电极沿胫骨结节远端5 cm (A)、10 cm (B)和15 cm (C)的前缘放置，并拍摄正位x线图像。测量AC、AB、BC线与胫骨轴线的夹角。结果:AC线、AB线、BC线与胫骨轴线的平均夹角分别为1.09、2.22、- 0.02。−3°~ +3°范围内的比例分别为86.8、64.8和92.3。结论:胫骨结节远端10-15 cm连接线可作为全膝关节置换术的参考线。

People with severe carpal tunnel syndrome with thenar muscle atrophy suffer from loss of dexterity of the affected hand, which hinders their daily lives. There are different options for opponensplasty. The more traditional option is Camitz operation combined with open carpal tunnel release (OCTR). Another option is to use the flexor digitorum superficialis of the ring finger (FDS4) for opponensplasty and to combine it with endoscopic carpal tunnel release (ECTR). In this study, we prospectively compared the surgical outcomes of these two methods. A total of 27 cases were recruited (13 Camitz + OCTR; 14 FDS 4 + ECTR). Both groups showed good improvement in numbness, pulp-pinch strength, Kapandji score, thumb dexterity and hand function. The technique of FDS4 + ECTR had additional benefits of earlier restoration of thumb opposition and dexterity. In addition, FDS4 + ECTR was demonstrated to restore stronger pulp-pinch strength.

The number of total hip arthroplasties increases every year as the population ages. The purpose of the study was to evaluate mid-term clinical and radiological results for a minimum of two years and the survival rate at the 5-year follow-up period using a fully hydroxyapatite (HA)-coated stem. A single-center retrospective observational study was conducted, in which 121 primary total hip arthroplasties (THA) were performed between 2013 and 2015 using a standard offset Corail fully HA-coated stem. The study included 108 patients, with a median age among all patients of 55.00 years (range 18.0–79.0 years). The median follow-up time was 4 years and 9 months. Stem survival for any reason was 98.4% at 5 years. The mean Harris Hip Score and Engh Grading Scale before surgery and at the follow-up visit show statistically significant improvement, accordingly (44.70 vs 98.13; p < 0.001) and (17.42 vs 19.68; p < 0.01). There is no statistically significant correlation between radiological and clinical results and no correlation between follow-up time and results. A completely coated hydroxyapatite standard offset Corail stem shows an excellent survival rate for a 5-year follow-up. Although the radiological results are not perfect, the clinical evaluation shows that the patients are satisfied and are not limited in their daily activities as before the surgery.
随着人口老龄化，全髋关节置换术的数量每年都在增加。该研究的目的是评估至少2年的中期临床和放射学结果，以及5年随访期间使用全羟基磷灰石(HA)涂层茎的生存率。进行了一项单中心回顾性观察性研究，其中2013年至2015年间使用标准偏移Corail全ha涂层杆进行了121例原发性全髋关节置换术(THA)。该研究纳入了108例患者，所有患者的中位年龄为55.00岁(范围18.0-79.0岁)。中位随访时间为4年9个月。5年生存率为98.4%。术前和随访时Harris髋关节评分和评分量表的平均改善有统计学意义(44.70 vs 98.13;P < 0.001)和(17.42 vs 19.68;p < 0.01)。影像学结果与临床结果无统计学意义相关，随访时间与结果无统计学意义相关。在5年随访中，完全包被羟基磷灰石标准偏移的Corail茎显示出极好的存活率。虽然放射学结果并不完美，但临床评价表明患者满意，并且不像术前那样限制日常活动。
