Abstract Study design A retrospective cohort study. Objective To investigate the radiological and clinical outcomes of patients with or without pedicle-screw rod fixation (PSRF) in OLIF surgery. Methods Between June 2017 and December 2019, 66 consecutive patients who underwent OLIF surgery at two centers were divided into stand-alone and combined groups according to whether or not PSRF was used. Imaging and clinical data were collected preoperatively, postoperatively, 3 and 6 months postoperatively, and at the last follow-up. Related coefficient and multiple linear regression analysis was used to detect the influencing factors of cage subsidence (CS). Results There was a lower baseline BMD in the combined group (p = 0.005). The combined group showed superior VAS score at 3 months postoperatively, although there was no difference in long-term VAS and ODI scores between the two groups. The foraminal height (FH) of the two groups was comparable at preoperatively, postoperatively, and 3 months postoperatively, but the combined group showed better maintenance of FH at 6 months postoperatively (p = 0.049) and last follow-up (p = 0.019). The total CS (tCS) of the combined group was lower than that of the stand-alone group during the whole follow-up period (all p ≤ 0.001). Multiple linear regression suggested that lower BMD was the risk factor for main CS, and PSRF could significantly reduce the BMD threshold for severe CS (−4.77 vs −1.38). Conclusions OLIF combined with PSRF can effectively avoid foraminal height loss and prevent severe CS, which may be more suitable for patients with osteoporosis or osteopenia and improve clinical outcomes.

Background: The purpose of this study was to compare the clinical outcomes after first metatarsophalangeal (MTP) joint arthrodesis for hallux rigidus between patients who underwent primary arthrodesis and those who had had a prior surgery for hallux valgus. Methods: Our design was a retrospective cohort study comparing 29 patients who underwent primary arthrodesis (primary group) and 34 patients with hallux rigidus after hallux valgus surgery (secondary group). The clinical assessment included the American Orthopaedic Foot & Ankle Society (AOFAS) score and a visual analog scale (VAS) for pain. Radiological evaluation was also performed. Overall, the mean postoperative follow-up was 3.4 (range, 2-5) years. Results: At final follow-up, AOFAS and VAS pain scores significantly improved in both groups ( P = .001). However, the mean AOFAS ( P = .001) and VAS pain ( P = .008) scores were significantly better in the primary group than in the secondary group. Radiologically, there were no significant differences between the groups in any angle after arthrodesis. Revision surgeries were not required in the primary group. In the secondary group, there was 1 revision due to deep infection, and 3 other patients required dorsal plate removal. Excluding plate removal, the Kaplan-Meier survival at 3 years was not significantly different between groups ( P = .775). Conclusion: Although arthrodesis of the first MTP joint was an effective procedure for hallux rigidus, the clinical outcomes in patients who had prior hallux valgus surgery were worse than those for patients who underwent primary surgery for hallux rigidus. Level of Evidence: Level III, retrospective cohort study.

Abstract Background Lateral tibial plateau fractures (TPFs) are often treated with conventional open reduction and internal fixation (ORIF) through standard anterolateral sub-meniscal arthrotomy. There has been increasing support for “bidirectional rapid redactor” device-assisted closed reduction and internal fixation (CRIF) for treating TPFs. The aim of the present study is to compare the clinical and radiological outcomes between CRIF and ORIF procedures. Methods We performed a retrospective cohort study of 55 lateral TPF patients (Schatzker types I–III) who accepted surgical treatment at our trauma level 1 center between January 2016 and January 2018. They were divided into the CRIF group (32 patients) and the ORIF group (23 patients) based upon the different surgical protocols. The patients’ clinical outcome analysis was evaluated by using the Knee Society Score (KSS) and Rasmussen’s clinical score. For radiological assessment, changes in tibial plateau width (TPW), articular depression depth (ADD), medial proximal tibial angle (MPTA), and posterior tibial slope angle (PTSA) were evaluated using radiographs and computed tomography (CT) scan. Results The CRIF group had a mean follow-up of 28.9 months, and the ORIF group had a mean follow-up of 30.7 months (p>0.05). Furthermore, there was no statistically significant difference in terms of age, gender, injury mechanism, follow-up time, time interval from injury to surgery, and Schatzker classification in the two groups. With respect to the clinical outcomes including the KSS score and Rasmussen’s clinical score, there was also no significant difference (p>0.05). Nevertheless, the CRIF group had lower intra-operative blood loss, shorter hospitalization days, and better range of movement of the knee joint than the ORIF group (p<0.05). Furthermore, CRIF had better radiological results when compared to the ORIF group using Rasmussen’s radiological score (p<0.05), although no significant difference was observed in TPW, ADD, MPTA, and PTSA between the two groups (p>0.05). Conclusion The present study showed that CRIF could achieve comparable clinical outcomes and better radiological results for treating lateral TPFs as compared with conventional ORIF.

Abstract Objectives Obesity prevalence is estimated at 34% in U.S. military retirees and 28% in beneficiaries of military healthcare, with common comorbidities being type 2 diabetes (T2D), hypertension, and hyperlipidemia. Stressors experienced during active duty service result in higher risk for disabling musculoskeletal injuries, psychological trauma, and alcohol abuse; all of which debilitate healthy weight loss efforts. No literature exists on the demographics and clinical outcomes of military retirees who elect bariatric surgery. The purpose of this study was to assess demographics and determine clinical outcomes of retirees and beneficiaries following bariatric surgery. It was hypothesized that pre-operative weights and comorbidity remission would be higher in the military retiree group. Methods A retrospective cohort study assessed military retirees and beneficiaries who underwent sleeve gastrectomy or gastric bypass surgery at a military treatment facility in 2014. Percent total weight loss (%TWL) and remission of pre-existing comorbidities (T2D, hypertension, and hyperlipidemia) at one year follow-up were primary outcomes and compared using Student's T tests and chi-squared contingency analysis. Additional statistical analyses included a Wilcoxon-Mann-Whitney test and backwards stepwise regression. Results Ninety-eight patients (64 beneficiaries and 34 retirees) were included with mean ages of 48 and 52 years, respectively. Student's T test and Wilcoxon-Mann-Whitney test confirmed that beneficiaries achieved greater %TWL at one year follow-up, 30.2% vs. 25.8% (p &lt; 0.05) and 55.5 vs. 38.2 mean rank (p &lt; 0.01), respectively. Beneficiaries and retirees achieved similar remission of T2D, hypertension, and hyperlipidemia. Patient's sex and surgery type were significant predictors of %TWL variation between groups at one year follow-up. These variables accounted for 9% of the %TWL variance. Conclusions Retirees who elect bariatric surgery lose less weight than their beneficiary counterparts. Etiology of this poorer outcome remains unclear, but further research may demonstrate need for improving healthcare resources provided to military retirees.

Background/Aims: To investigate clinical outcomes of remote peritoneal dialysis (PD) patients in Southern China. Methods: In this retrospective cohort study, incident remote PD patients managed with a comprehensive follow-up program in our PD center were included and clinical outcomes were estimated. Results: One thousand and five remote PD patients with mean age 46.1 ± 14.6 years, of which 38.1% were women, were followed-up for a median of 35.7 months. Patient survival rates were 95.4, 84.7 and 71.8% and death-censored technique survival rates were 98.6, 92.3 and 83.4% at 1, 3 and 5 years, respectively. Peritonitis rate was 0.16 episodes per patient-year. Advanced age, diabetes mellitus, shorter peritonitis-free survival time, poor compliance for regular visiting nephrologists and lower hemoglobin predicted all-cause mortality of remote PD patients. Conclusion: The remote PD patients in Southern China managed with comprehensive follow-up program had favorable clinical outcomes, which indicated that home-based PD therapy could be an appropriate treatment option for remote end-stage kidney disease patients.
