Purpose: To evaluate long-term clinical and radiological results of cervical laminectomy without adjuvant-instrumented fusion for degenerative spinal cord compression.
Methods: A retrospective follow-up study of patients in which clinical data (n = 207), questionnaires (n = 96) and fluoroscopy (n = 77) were reviewed.
Results: Postoperative perceived recovery was reported by 76 and 63 % of patients at 3 months and 9 years, respectively. Functional status remained unchanged. The incidence of kyphosis and segmental instability was 15 and 18 %, respectively, and occurred almost exclusively if preoperative lordosis was <20°. Neither kyphosis nor segmental instability correlated to perceived recovery and no predisposing variables were identified.
Conclusions: Cervical laminectomy without adjuvant-instrumented fusion should be considered as a treatment for compressive degenerative cervical myelopathy in patients with a lordotic cervical spine without congenital deformities. Additional reconstructive correction of the cervical spine is only proven appropriate in selected cases.

Unloader brace or high tibial osteotomy in the treatment of the young patient with medial knee osteoarthritis: a randomized controlled trial.
Acta Orthop
January 2025
Department of Orthopaedics and Sports Medicine, Erasmus MC University Medical Centre Rotterdam; Department of General Practice, Erasmus MC University Medical Centre, Rotterdam, the Netherlands.
Background And Purpose: For medial knee osteoarthritis (OA), operative and nonoperative treatment options are available. Two widely applied unloading therapies are a valgus unloader brace and a high tibial osteotomy (HTO). We aimed to compare the effects of a valgus unloader knee brace with an HTO on knee pain after 1 year in patients with symptomatic medial knee OA.

Enhancing panoramic dental imaging with AI-driven arch surface fitting: Achieving improved clarity and accuracy through an optimal reconstruction zone.
Dentomaxillofac Radiol
January 2025
Department of Oral and Maxillofacial Radiology, School of Dentistry, Pusan National University, Yangsan, 50612, Korea.
Objectives: This study aimed to develop an automated method for generating clearer, well-aligned panoramic views by creating an optimized three-dimensional (3D) reconstruction zone centered on the teeth. The approach focused on achieving high contrast and clarity in key dental features, including tooth roots, morphology, and periapical lesions, by applying a 3D U-Net deep learning model to generate an arch surface and align the panoramic view.
Methods: This retrospective study analyzed anonymized cone-beam CT (CBCT) scans from 312 patients (mean age 40 years; range 10-78; 41.
Bilateral facial nerve palsy in a patient with West Nile neuroinvasive disease.
J Infect Dev Ctries

University Clinic for Infectious and Tropical Diseases of the University Clinical Centre of Serbia, Belgrade, Serbia.
Introduction: Bilateral facial nerve palsy (FNP) is a rare condition that is idiopathic in only 20%. FNP is the most common cranial neuropathy in West Nile neuroinvasive disease (WNND) but is usually unilateral and only a few cases of bilateral FNP have been reported.
Case: We present a case of a 65-year-old woman with confirmed WNND and simultaneous bilateral FNP.
