RESUMO
PURPOSE: To investigate the clinical efficacy and prognostic factors associated with autologous osteoperiosteal transplantation for the treatment of single cystic osteochondral lesions of the talus (OLT). METHODS: The clinical data of patients with single cystic OLT undergoing autologous osteoperiosteal transplantation at the Department of Foot and Ankle Surgery of our hospital between 2018 and 2022, including complete follow-up, were retrospectively analyzed. Imaging data from each patient were imported into Mimics software to measure the surface area, volume and depth of the lesions. Then, the talus nine-compartment partitioning method was used to partition the injury site. Preoperative and final follow-up assessments were performed using the American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) for pain and 36-item Short-Form Health Survey (SF-36) to evaluate treatment efficacy and analyze prognostic factors. RESULTS: Of the 31 patients with single cystic OLT with a complete set of follow-up data, there were 17 males and 14 females, with a mean age of 43.3 ± 13.6 years, a mean follow-up time of 30.1 ± 14.0 months and a mean illness duration of 30.4 ± 20.0 months. The postoperative final follow-up AOFAS score was 90.7 ± 5.5; this represented significant improvement when compared to the preoperative score of 57.0 ± 8.5 (P < 0.001). The final postoperative follow-up VAS score was 18.5 ± 8.3; this was significantly better than the preoperative score of 57.8 ± 8.7 (P < 0.001). The physical component summary (PCS) score and mental component summary (MCS) score on the SF-36 scale showed significant improvement at the final postoperative follow-up when compared to preoperative scores (p < 0.001). No other complications were observed during follow-up, such as wound infection or pain at the donor site. One of the patients showed less improvement, which may be related to premature weight-bearing or re-sprained ankle after surgery. There was no significant correlation between the duration of illness, gender and the location, depth, surface area and volume of the OLT and the postoperative scores. However, patient age showed a significant negative correlation with the postoperative SF-36 PCS and MCS scores. CONCLUSION: Autologous osteoperiosteal transplantation for single cystic OLT demonstrated good clinical efficacy with a low incidence of complications. Furthermore, age represents an important factor influencing prognosis. LEVEL OF EVIDENCE: Level II.
RESUMO
PURPOSE: Analyzing the correlation between patients' basic information, three-dimensional parameters after calcaneal fractures, and the prognosis of calcaneal fractures. METHODS: A retrospective analysis was conducted on 43 patients with calcaneal fractures who underwent surgical treatment in the Foot and Ankle Surgery, Xi'an Honghui Hospital, from September 2019 to August 2022. Patient demographics including gender and age were collected, as well as the preoperative posterior articular surface collapse area, number of fracture fragments, length, width, height, and volume of the calcaneus obtained from preoperative three-dimensional imaging. Patients were followed up for VAS, AOFAS, and SF-36 scores. Correlation analysis was performed on the obtained data. RESULTS: All 43 included patients received complete follow-up, including 40 males and 3 females, with an average follow-up time of 35.37 ± 10.73 months, and an average age of 43.98 ± 12.08 years. All patients' VAS, AOFAS, and SF-36 scores at the last follow-up showed no correlation with patient age, gender, or the area of posterior articular collapse, number of fracture fragments, length, width, height, or volume of the calcaneus. CONCLUSIONS: The prognosis of calcaneal fractures is unrelated to three-dimensional factors such as patient age, gender, length, width, height, volume of the calcaneus, area of the posterior joint, and number of fracture fragments.

Purpose: This study aims to investigate the psychological status of patients with Hepple V osteochondral lesions of the talus (OLT) and evaluate the effect of autologous osteoperiosteal transplantation (AOPT) on their psychological well-being. Methods: Fifty patients with Hepple V OLT who underwent AOPT at the Comprehensive Foot and Ankle Surgery Ward of Xi'an Honghui Hospital from November 2021 to May 2023 were included in this study. The patients were divided into two groups based on the presence or absence of preoperative symptoms of anxiety/depression. Group A comprised patients with preoperative symptoms, while Group B included patients without such symptoms. Preoperative and final follow-up assessments included the Hospital Anxiety and Depression Scale for evaluating anxiety and depression, the visual analogue scale for pain assessment, and the American Orthopaedic Foot and Ankle Society scores for assessing ankle and hindfoot function. Results: Among the 50 Hepple V OLT patients who obtained complete follow-up, twenty-four had preoperative symptoms of anxiety/depression, with an incidence rate of up to 48%. Patients in Groups A and B showed significant improvement in all evaluation indexes after AOPT compared to the preoperative period, but the overall prognosis of Group A was poorer than that of Group B. Conclusion: AOPT can effectively improve patients' pain, functional activities, and psychological status, and there is a significant correlation between patients' preoperative psychological status and prognosis.
RESUMO
OBJECTIVE: To determine the range of motion and stability of the human cadaveric cervical spine after the implantation of a novel artificial disc and vertebra system by comparing an intact group and a fusion group. METHODS: Biomechanical tests were conducted on 18 human cadaveric cervical specimens. The range of motion and the stability index range of motion were measured to study the function and stability of the artificial disc and vertebra system of the intact group compared with the fusion group. RESULTS: In all cases, the artificial disc and vertebra system maintained intervertebral motion and reestablished vertebral height at the operative level. After its implantation, there was no significant difference in the range of motion (ROM) of C3-7 in all directions in the non-fusion group compared with the intact group (p>0.05), but significant differences were detected in flexion, extension and axial rotation compared with the fusion group (p<0.05). The ROM of adjacent segments (C3-4, C6-7) of the non-fusion group decreased significantly in some directions compared with the fusion group (p<0.05). Significant differences in the C4-6 ROM in some directions were detected between the non-fusion group and the intact group. In the fusion group, the C4-6 ROM in all directions decreased significantly compared with the intact and non-fusion groups (p<0.01). The stability index ROM (SI-ROM) of some directions was negative in the non-fusion group, and a significant difference in SI-ROM was only found in the C4-6 segment of the non-fusion group compared with the fusion group. CONCLUSION: An artificial disc and vertebra system could restore vertebral height and preserve the dynamic function of the surgical area and could theoretically reduce the risk of adjacent segment degeneration compared with the anterior fusion procedure. However, our results should be considered with caution because of the low power of the study. The use of a larger ...
