The Assessment of the Reduction Algorithm in the Treatment for "Logsplitter" Injury.

As a rare and exceptional injury with significant syndesmotic disruption, the outcome of Logsplitter injury remains poor and unfavorable. In this study, we retrospectively investigated the relationship between the intraoperative reduction quality and the prognosis such as the posttraumatic osteoarthritis to help surgeons achieve better functional outcomes for this high-energy transsyndesmotic ankle fracture dislocation. From January 2015 to February 2019, 31 patients (average 37.6 ± 9.4 years with 19 male and 12 female) diagnosed with the Logsplitter injury were treated by ORIF procedure and enrolled in our study. Particularly, nine vital radiographic parameters including medial clear space, talocrural angle, superior clear space, tibiofibular clear space, tibiofibular overlap, talar tilt, coin sign, tibial medial malleolus angle, and fibular lateral malleolus angle were measured from a postoperative film (AP and mortise view). Next, we compared the clinical outcome by using range of ankle motion, AOFAS scores, Burwell-Charnley score system, and Kellergen-Lawrence criteria from the patients who obtained the intraoperative anatomical reduction with those who failed. Our results showed that AOFAS score with all the patients was 79.33 ± 5.82 at the final follow-up. 14 (45.1%) of 31 patients were observed with radiographic posttraumatic arthritis of the ankle joint with an average Kellgren-Lawrence score of 1.75 ± 1.6 at final follow-up. Most importantly, our results proved that there were significant differences between the patients eligible for anatomical reduction quality with those who failed with regard to OA rate (33.3% vs. 85.7%, P = 0.003) and AOFAS scores (75.33 ± 6.53 vs. 66.89 ± 4.28, P = 0.037) at the final follow-up. Furthermore, the functional outcome after the operation showed an increased range of motion of the ankle joint of the patients obtained anatomical reduction compared with those who failed (P < 0.05). In this study, the significant discrepancy with regard to the functional outcomes was observed between the acceptable and unacceptable radiographic parameters, indicating that the quality of intraoperative reduction is scientifically significant and thus can be utilized as the major factor to predict the clinical outcomes for Logsplitter injuries. Moreover, this reduction algorithm arising from our study can also be applied to other ankle fractures and dislocation involving syndesmotic complex.

Is nonstructural bone graft useful in surgical treatment of lumbar spinal tuberculosis?: A retrospective case-control study.

Surgical intervention is an important option for treating spinal tuberculosis. Previous studies have reported different surgical procedures and bone grafts for it. To our knowledge, few studies demonstrated the clinical results of using nonstructural autogenous bone graft in surgical treatment of spinal tuberculosis.The purpose of this study is to compare the clinical outcomes of surgical management lumbar spinal tuberculosis by one-stage posterior debridement with nonstructural autogenous bone grafting and instrumentation versus anterior debridement, strut bone grafting combined with posterior instrumentation.A total of 58 consecutive patients who underwent surgical treatment due to lumbar spinal tuberculosis from January 2011 to December 2013 were included. A total of 22 patients underwent one-stage posterior debridement, nonstructural autogenous bone grafting, and instrumentation (group A), and 36 patients received anterior debridement, strut bone grafting combined with posterior instrumentation (group B). The operative duration, total blood loss, perioperative transfusion, length of hospital stay, hospitalization cost, and complications were recorded. The bony fusion of the graft was assessed by computed tomography scans. American Spinal Injury Association (ASIA) Impairment Scale was used to evaluate the neurological function of patients in the 2 groups.All the patients were followed up, with a mean follow-up duration of 21.6 ±â€Š5.7 months in group A and 22.3 ±â€Š6.2 months in group B (P = 0.47). The average operative duration was 257.5 ±â€Š91.1 minutes in group A and 335.7 ±â€Š91.0 minutes in group B (P = 0.002). The mean total blood loss was 769.6 ±â€Š150.9 mL in group A and 1048.6 ±â€Š556.9 mL in group B (P = 0.007). Also, significant differences were found between the 2 groups in perioperative transfusion volumes, length of hospital stay, and hospitalization cost (P < 0.05), which were less in group A compared with group B. Patients with ASIA grade C/D in the 2 groups were improved with 1 to 2 grades after the surgery with no statistical difference (P = 1.000). The perioperative complications rate was 9.1% (2/22) in group A and 13.9% (5/36) in group B (P = 0.897).Based on a retrospective study, the procedure of one-stage posterior debridement, nonstructural autogenous bone grafting, and instrumentation has a significant shorter operative duration, lower blood loss and perioperative transfusion, shorter hospital stay, and less hospitalization cost compared with the one of anterior debridement, strut bone grafting combined with posterior instrumentation for treating lumber spinal tuberculosis.
