Open axillary arterial injury is life-threatening, and upper-extremity reperfusion must be performed within approximately 6 h. We present the case of a patient who underwent reperfusion of the upper limb and nerve reconstruction of the post-ganglionic brachial plexus injury in one stage while maintaining stable vital signs. The injury was an avulsion with no fracture.

- The study examined the 1-year results of four treatments for lumbar disc herniation: transforaminal full-endoscopic lumbar discectomy (TF-FED), condoliase injection, open discectomy (OD), and microendoscopic discectomy (MED) among 279 patients.
- No significant differences were found in pain and functional outcomes (JOABPEQ, VAS scores), complication rates, or nerve injury rates among the surgical methods, but condoliase injection had a higher reoperation rate due to residual herniation.
- TF-FED and condoliase injection were less expensive and involved less blood loss since they can be done under local anesthesia, but both showed increased disc degeneration and end
Article Synopsis
- The study aimed to compare the effectiveness of O-arm navigation versus conventional fluoroscopy for corrective posterior fixation in cervical spinal injuries in 11 patients from February 2016 to May 2021.
- Results showed that patients in the O-arm group had a significantly higher number of pedicle screws used compared to those in the fluoroscopy group (6.4 vs 2.7) without any significant breaches in screw placement accuracy.
- The conclusion suggests that O-arm navigation enhances the accuracy of screw insertion, potentially allowing for a broader application of pedicle screws in complex cervical spinal surgeries compared to traditional methods.
Pseudomeningocele is an extradural cystic collection of cerebrospinal fluid (CSF) and is rare and typically asymptomatic. However, pseudomeningocele is sometimes associated with symptoms. Whether symptomatic pseudomeningocele is best treated conservatively or surgically remains controversial.

We examined the changes in postoperative MRI findings and their relation to early clinical symptoms.
Methods: In total, 33 patients underwent FED under local anesthesia.
