In different angles of lamina open-door, the improvement rate of neurological function after surgery had no statistically significant difference between 2 groups. When the open-door angle is maintained between 15 and 30 degrees, it can reduce the incidence of C5 palsy in the hinge side and AS, but we should prevent reclosure of the lamina open-door.

The 2 surgical procedures have similar clinical effects in treating multisegmental CMUR. However, the EOLF group demonstrated shorter operative time, less blood loss, and fewer complications; therefore, it proved to be a more effective and safer method.

Intradural mature teratomas are spinal tumors containing all the germinal layers and rarely present in adulthood. This study describes an unusual case of intradural mature teratoma in a 19-year-old male who presented with persistent lower limb pain and difficulty in micturition. The magnetic resonance imaging (MRI) scan showed heterogeneously enhancing intramedullary mass in the L3-L4 vertebral region and was associated with tethering of the spinal cord. Scalloping of the posterior aspect of vertebral body and narrowing of the pedicles were present. Subtotal excision of the tumor was done because of its adherence to the conus. Attempt to completely excise such adherent intramedullary tumors can lead to permanent neurological deficits. The tissue was sent for histopathological examination which showed tissue from all the three germinal layers confirming the diagnosis. The patient showed improvement of symptoms following the surgery. This study also compared the literature of similar cases and the treatments available for this disease.

Introductions: Patients of stenosing tenosynovitis or trigger finger presents with pain, swelling, limitation of finger movement, and triggering. Thickening of the A1 pulley, with resultant entrapment of flexor tendons, is the primary pathology. In failed conservative treatment, surgical release by open or percutaneous technique is used. The aim of this study was to evaluate the results of percutaneous release of trigger fingers using hypodermic 18-gauge needle under local anesthesia. Methods: A cross sectional study of percutaneous release of trigger fingers using hypodermic 18-gauge needle under local anesthesia was performed in outpatient clinic at Janaki Medical College Teaching Hospital, Janakpur, Nepal, from July 2016 to September 2017. Informed consent was obtained. All the patients were followed up on 3rd day, 1st week and one month in outpatient department, and further telephone follow up at three and six months after surgery. Results: There were 38 patients, female 25 and male 13, age 24 to 67 years. Successful release was achieved in 36/38 (95%) with normal activities within 48 hours. None had complications like digital neurovascular injury or tendon bowstringing. One patient had superficial skin infection and was treated successfully with oral antibiotics. Two (5.2%) had pain and recurrent triggering requiring open release in the first week. At one, three and six months follow up patients reported no triggering of released fingers. Conclusions: Percutaneous release with hypodermic 18-gauge needle under local anesthesia in the treatment of trigger finger was an effective and convenient method with a low complication rate.
