OBJECTIVE: Spinal cord stimulation has been proven highly effective in the treatment of Complex Regional Pain Syndrome (CRPS). The definitive implantation of a neurostimulator is usually preceded by a therapeutic test (trial), which has the purpose of identifying whether the patient would respond positively to neuromodulation or not. The present study aims to analyze the surgical results of spinal cord stimulation in type 1 CRPS patients who have not undergone trial. PATIENTS AND METHODS: From January 2011 to August 2017, 160 patients underwent implantation of spinal cord neurostimulator...

In order to provide best control of the regeneration process for each individual patient, the release of protein drugs administered during surgery may need to be timely adapted and/or delayed according to the progress of healing/regeneration. This study aims to establish a multifunctional implant system for a local on-demand release, which is applicable for various types of proteins. It was hypothesized that a tubular multimaterial container kit, which hosts the protein of interest as a solution or gel formulation, would enable on-demand release if equipped with the capacity of diameter reduction upon external stimulation...

Electrical high-frequency stimulation (HFS), using implanted electrodes targeting various brain regions, has been proven as an effective treatment for various neurological and psychiatric disorders. HFS in the deep region of the brain, also named deep-brain stimulation (DBS), is becoming increasingly important in clinical trials. Recent progress in the field of high-frequency DBS (HF-DBS) surgery has begun to spread the possibility of utilizing this invasive technique to other situations, such as treatment for major depression disorder (MDD), obsessive-compulsive disorder (OCD), and so on...

Implantation rates of hypoglossal nerve stimulators, such as INSPIRE, are increasing. The device is still in its early stages of complication reporting, which to date includes implant related infection requiring device removal, and stimulation lead cuff dislodgement requiring replacement. Here we present a 48-year-old female who experienced generator migration and stimulator lead tension requiring an additional operation in order to resecure the generator device. This proved unsuccessful and a second surgery was performed with complete relocation of the device generator to inhibit device migration...

BACKGROUND: Turf toe is a term used to describe a hyperextension injury to the first metatarsophalangeal joint. Although the vast majority of turf toe injuries can be treated successfully without operative intervention, there are instances where surgery is required to allow the athlete to return to play. Although there is a plethora of literature on turf toe injuries and nonoperative management, there are currently few reports on operative outcomes in athletes. METHODS: We obtained all cases of turf toe repair according to the ICD-10 procedural code...

BACKGROUND: Flexible flatfoot (FFF) is a common alteration of the foot diagnosed in the pediatric population causing pain and decreased quality of life. Surgical treatment via arthroereisis of the subtalar joint can be recommended when non-invasive options do not result in sufficient pain relief. While clinical outcome of subtalar joint arthroereisis is generally positive, no functional evaluation has thus far been reported following surgery. RESEARCH QUESTION: The aim of this study was to assess the effects of two arthroereisis implants for the correction of bilateral FFF on foot and lower limb biomechanics during gait...

INTRODUCTION: Stereoelectroencephalography (sEEG) is a diagnostic procedure for patients with refractory focal epilepsies that is performed to localize and define the epileptogenic zone. In contrast to grid electrodes, sEEG electrodes are implanted using minimal invasive operation techniques without large craniotomies. Previous studies provided good evidence that sEEG implantation is a safe and effective procedure; however, complications in asymptomatic patients after explantation may be underreported...
