In this article we review the background of anterior cervical plating for one- and two-level diskectomy for degenerative disease and provide background justification for the design and testing of a cervical plate composed of a resorbable material. The design of the plate is discussed with special reference to modifications of implant design and implant tools compared with metallic plates that are necessary because of the different mechanical properties of the less rigid material. Our cadaveric and animal in vivo testing methodologies are described and a novel testing method for reliably quantifying graft containment is also described. Data from a representative sample are presented. Advantages and disadvantages of resorbable plating are discussed.

Objective: To investigate the effects of modified twin-block appliances (MTBA) on obstructive sleep apnea (OSA) and mandibular retrognathia and the changes in the upper airway, hyoid bone position, and hypoxia-related inflammatory marker levels in children with OSA.
Methods: This study included children with OSA and mandibular retrognathia and those with class I without mandibular retrognathia (n = 35 each). The experimental group comprised children with OSA and mandibular retrognathia managed using MTBA.

In Japan, cervical artificial disc replacement was approved by the Pharmaceuticals and Medical Devices Agency in December 2017, and two products, Mobi-C by Zimmer Biomet and Prestige LP by Medtronic, are on the market. Cervical artificial disc replacement preserves cervical motion; however, the device must be place carefully on the midline to take full advantage of its features. In addition, a reliable foraminotomy is required to cure or prevent radiculopathy due to residual foraminal stenosis.

Anterior cervical fixation is an excellent surgical technique for the removal of anterior compressive elements affecting the spinal cord and nerve roots while addressing cervical instability. However, it is important to recognize the unique challenges posed by the proximity of critical structures, including the trachea, esophagus, carotid sheath, and recurrent laryngeal nerve. Access to the upper cervical spine is often limited to the mandible.

Introduction: Thoracic outlet syndrome (TOS) encompasses multiple symptoms produced by compression of the neurovascular bundle within the thoracic outlet. The subtypes of thoracic outlet are termed for the major affected structure including neurogenic (nTOS), venous (vTOS), and arterial (aTOS) thoracic outlet syndrome. Neurogenic thoracic outlet syndrome accounts for over 95 percent of thoracic outlet syndrome cases and occurs from compression of the brachial plexus.
