Abstract Background: If bone union is expected, conservative treatment is generally selected for lumbar spondylolysis. However, sometimes conservative treatments are unsuccessful. We sought to determine the factors associated with failure of bony union in acute unilateral lumbar spondylolysis with bone marrow edema including contralateral pseudoarthrosis.Methods: This study targeted unilateral lumbar spondylolysis treated conservatively in high school or younger students. Conservative therapy was continued until the bone marrow edema disappeared on MRI and bone union was investigated by CT. We conducted a univariate analysis of sex, age, pathological stage, lesion level complicating the contralateral bone defect, lesion level, and intercurrent spina bifida occulta, and variables with p < 0.1 were considered in a logistic regression analysis. An item with p < 0.05 was defined as a factor associated with failure of bony union.Results: We found 92 cases of unilateral spondylolysis with bone marrow edema and 66 cases were successfully treated conservatively. Failure of bony union in unilateral lumbar spondylolysis with bone marrow edema was associated with advanced pathological stage (p = 0.004), contralateral pseudoarthrosis (p < 0.001), and L5 lesion level (p = 0.002). The odds ratio was 20.0 (95% CI 3.0–193.9) for advanced pathological stage, 78.8 (95% CI 13–846) for contralateral pseudoarthrosis, and 175 (95% CI 8.5–8192) for L5 lesion level.Conclusions: Conservative therapy aiming at bony union is contraindicated in cases of acute unilateral spondylolysis when the pathological stage is advanced, the lesion level is L5, or there is contralateral pseudoarthrotic spondylolysis.

Background Although segmental wire fixation has been successful in the treatment of nonathletes with spondylolysis, no information exists on the results of this type of surgery in athletes. Purpose To evaluate the outcome of surgical repair of pars interarticularis defect by segmental wire fixation in young athletes with lumbar spondylolysis. Methods Between 1993 and 2000, 20 athletes (6 women and 14 men; average age, 23.7) with lumbar spondylolysis were treated surgically with this technique. They were actively engaged in sports such as baseball, tennis, and golf. Nineteen athletes had one level of spondylolysis and one athlete had two levels. The level of spondylolysis was L4 in 2 athletes and L5 in 19. The average follow-up period was 3.5 years (range, 1.3 to 8.6). Surgical outcome was evaluated by radiographic examination, the Japanese Orthopaedic Association score, preoperative and postoperative sports activity levels and intensities, and the presence of complications. Results Bony fusion at the site of spondylolysis was obtained in all cases, and the Japanese Orthopaedic Association score was increased significantly after surgery (preoperatively, 21.2 ± 3.9; postoperatively, maximum 27.7 ± 1.0; recovery rate, 80.4%). All of the patients returned to their sports activities, although at varying degrees. No severe complications were noted. Conclusion We recommend this technique in cases of lumbar spondylolysis in athletes who hope to resume their sports activities.

PurposeThe authors aim to examine how emojis interact with assertiveness in social media posts to encourage social media engagement and cooperation in environmental campaigns.Design/methodology/approachTwo experiments were used to test three hypotheses.FindingsStudy 1 shows that when assertive Twitter messages include the smiley-face emoji, study participants indicate stronger social media engagement and behavioral intentions to recycle used jeans. In Study 2, participants indicate stronger social media engagement and behavioral intentions to sign a petition for reducing plastic pollution when (non) assertive Facebook messages (do not) include emojis.Originality/valueThe current research advances our understanding about how emojis interact with assertive and nonassertive message tonality in environmental social media campaigns. This research also provides new insights showing that positive emotion is the psychological mechanism underlying matching effects of emoji and message assertiveness.

AbstractBackground: Lumbar spondylolysis is a stress fracture of the lumbar vertebral arch that occurs frequently in adolescents. Lumbar spondylolysis has a high prevalence in athletes, especially baseball players. When lumbar spondylolysis occurs, restriction of sports activities is inevitable until the bony union is achieved. Therefore, prevention of the onset of lumbar spondylolysis is necessary, and it is necessary to elucidate the risk factors that influence the onset of the disease. An increase in lumbar lordosis angle may influence the development of lumbar spondylolysis because the lumbar lordosis angle increases the compressive stress in the vertebral arch. However, there are no reports on the effect of lumbar lordosis angle and the development of lumbar spondylolysis in adolescent baseball players. Therefore, the purpose of this study was to investigate the effect of lumbar lordosis angle on the development of lumbar spondylolysis in adolescent baseball players. METHODS: Eligible patients were those who visited the orthopedic clinic from January 1, 2018, to October 31, 2021. The selection criteria were male baseball players aged 11-18 years who visited the clinic, and the exclusion criteria were those whose superior endplate of L1 and superior endplate of S1 could not be identified in the MRI images. The existence of development of lumbar spondylolysis, lumbar lordosis angle, age, and pitching experience of the above patients will be assessed based on electronic medical records and imaging findings. Statistical analysis was performed using logistic regression analysis, with the objective variable being the existence of lumbar spondylolysis and the explanatory variables being the lumbar lordosis angle, age, and previous pitching experience.Discussion: This study examines the effect of the lumbar lordosis angle on the development of lumbar spondylolysis in adolescent baseball players. An increase in lumbar lordosis angle may influence the development of lumbar spondylolysis and may be a risk factor for the development of lumbar spondylolysis.
