Single lateral approach for open reduction and internal fixation of posterior malleolar fragment in Weber B rotational ankle fracture.

Ankle fractures involving the posterior malleolus are a relatively common injuries, but various surgical approaches are still being introduced, and the selection of an appropriate surgical method is still controversial. The aim of this study was to introduce the surgical method using a single lateral approach for open reduction and internal fixation for posterior malleolar (PM) fractures associated with Weber B type ankle fractures. In this retrospective study, the single lateral approach was used for osteosynthesis of the PM fracture with Weber B lateral malleolar fractures.

Early Reoperation Rates and Its Risk Factors after Instrumented Spinal Fusion Surgery for Degenerative Spinal Disease: A Nationwide Cohort Study of 65,355 Patients.

Reoperation is a major concern in spinal fusion surgery for degenerative spinal disease. Earlier reported reoperation rates were confined to a specific spinal region without comprehensive analysis, and their prediction models for reoperation were not statistically validated. Our study aimed to present reasonable base rates for reoperation according to all possible risk factors and build a validated prediction model for early reoperation.

Prediction of Recurrence in Pyogenic Vertebral Osteomyelitis by Artificial Neural Network Using Time-series Data of C-Reactive Protein: A Retrospective Cohort Study of 704 Patients.

Study Design: A retrospective cohort study.

Objective: The aim of this study was to develop recurrence-prediction models of pyogenic vertebral osteomyelitis (PVO).

Summary Of Background Data: Prediction of recurrence in PVO is crucial to avoid additional prolonged antibiotic therapy and aggressive spinal surgery and to reduce mortality.

Risk factors associated with multiple and missed gastric neoplastic lesions after endoscopic resection: prospective study at a single institution in south Korea.

Background/aims: Only a small part of visible gas tric mucosal lesion can be removed by endoscopic resection. This study is aimed to identify incidence rate and associated risk factors of multiple and missed gastric lesions, and proper timing of follow-up en doscopy.

Methodology: Endoscopic surveillance was performed on 1 week, and 1, 6, 12 months af ter endoscopic resection.
