Introduction: Minimally invasive transforaminal lumbar interbody fusion has proven effectiveness in treating spondylolisthesis, but there were few reports applying the technique from scarce resourcing developing countries. In this study, the authors report the results and share our experience of minimally invasive spinal transforaminal lumbar interbody fusion in spondylolisthesis treatment in Vietnamese patients. Materials and methods: In this study, the authors enroled 92 patients diagnosed with single-level, grade I or grade II lumbar spondylolisthesis from January 2019 to October 2022. Results: The median age in our study was 47.79±12.61 (range 15–75), the male/female ratio was 1/2.3. The mean disease duration was 28.57 months. Conventional X-ray images showed that there were 74 patients (80.43%) with spondylolisthesis grade I, 18 patients (19.57%) with grade II. Spondylolisthesis occured mainly in L4–L5 with 53 patients (57.61%). The isthmic sign was recorded in 16 patients (31.4%). The mean blood loss was 149.46 ml. Patients walked on average of 3.22 days after surgery. VAS score reduced significantly in both back and leg. Spinal function improved significantly with a preoperative Owestry Disability Index of 48.18% decrease to 15.18% 12 months after surgery. The surgical results were good and excellent at 95.00% after 12 months of surgery according to Macnab scale. The fusion rate reached 97.50%. Conclusions: The results of this Macnab's classification study show that minimally invasive spinal transforaminal lumbar interbody fusion is an effective treatment for spondylolisthesis with less pain, less blood loss after surgery, and high fusion rate.

Background:The traumatic dislocation of the radial head in children is commonly treated by closed reduction. Sometimes, however, this strategy of treatment may not be effective due to the location of soft tissues in the radio-shoulder joint. The literature presents a few cases of the irreducible radial head dislocation with ulnar plastic deformation. Because it is a relatively rare condition, such a traumatic dislocation can be easily missed. Neglected injuries can lead to unwanted complications and unpredictable surgical outcomes.Case presentation: This study presents a relatively rare case of traumatic radial head dislocation with ulnar plastic deformation in a 3-year-old child, which was successfully treated by open reduction. The examined case did not require osteotomy and ligamentous reconstruction. The initial attempt of closed reduction failed due to annular ligament interposition, which has been detected on MRI. After 3 months of treatment, the range of motion of the operated arm gradually improved. At the 6-month follow-up, the Mayo elbow-performance score indicated an excellent treatment outcome. Conclusions:The delayed treatment of radial head dislocation with ulnar plastic deformation can hinder the supination and pronation of the forearm, resulting in elbow/forearm deformity. The earlier this condition is detected, the easier it will be to treat it and the better the treatment outcome will be. The examined case of irreversible traumatic dislocation, successfully treated by open reduction, may help to treat radial head dislocation better.

The aim of the article is to present the first experience of applying a full-endoscopic posterior cervical foraminotomy and discectomy performed at Viet Duc University Hospital in Hanoi and describe the outcomes of such surgical intervention. This surgical series includes 20 patients underwent surgery through full-endoscopic posterior cervical foraminotomy and discectomy. The definitive diagnosis of the patients and the evidence for surgical treatment was radiculopathy due to lateral or intraforaminal disk herniation, foraminal stenosis, and lateral recess stenosis. Patients with discogenic cervical radiculopathy but with a contraindication to endoscopic posterior cervical foraminotomy and discectomy were not subject to surgical intervention. All patients underwent a CT and MRT examination of the cervical spine before and after surgery as complementary diagnostic methods. Besides radiological diagnostic methods, electroneuromyography and spondylography were performed with functional samples, i.e., with head tilts in the front and back, to eliminate segmental instability. The timing and degree of the root pain syndrome regression were assessed using a VAS scale (visual and analog scale) with a subsequent comparison of preoperative and postoperative performance. Immediately after the operation, all patients noted a complete or nearly complete regression of the pain syndrome.
