Robot-Assisted Positioning for Percutaneous Endoscopic Interlaminar Discectomy.
Orthop Surg
January 2025
Orthopaedic Department, Peking University Third Hospital, Beijing, China.
Objective: During percutaneous endoscopic interlaminar discectomy (PEID), a range of technologies including medical robotics, visual navigation, and spatial registration have been proposed to expand the application scope and success rate of minimally invasive surgery. The use of robotic technology in surgery is conducive to improving accuracy and reducing risk. This study aims to introduce a precise and efficient targeting method tailored for robot-assisted positioning under C-arm fluoroscopy inPEID.

Background: Robotic arm assisted total knee arthroplasty (RA-TKA) aims to improve accuracy in bone resection, implant positioning, and joint alignment compared to manual TKA (M-TKA). However, the learning curve of RA-TKA can disrupt operating room efficiency, increase complications, and raise costs. This study examines the operative time learning curve of RA-TKA using a single robotic system.

A boy with bilateral congenital anomalies of the upper extremities with transverse absence of the left arm (agenesis) and absence of right thumb (disgenesis), fixed elbow in extension due to humeroradial synostosis thought that the humerus was intact. His wrist could move passively with 50° flexion, 0° extension, and 70° radial deviation. The other 4 fingers were intact, 4-5 metatarsal bones were in synostosis, and the fifth finger was clinodactyly.

Introduction: Obstructive sleep apnoea (OSA) is characterised by blood oxygen desaturations and sleep disruptions manifesting undesirable consequences. Existing treatments including oral appliances, positive airway pressure (PAP) therapy and surgically altering the anatomy of the pharynx have drawbacks including poor long-term adherence or often involving irreversible, invasive procedures. Bilateral hypoglossal nerve stimulation (HNS) is a new treatment for managing OSA, and this study is intended to determine whether an HNS system is a safe and effective treatment option for adults with OSA.

Purpose: Optimizing fracture reduction quality is key to achieve successful osteosynthesis, especially for epimetaphyseal regions such as the proximal humerus (PH), but can be challenging, partly due to the lack of a clear endpoint. We aimed to develop the prototype for a novel intraoperative C-arm-based aid to facilitate true anatomical reduction of fractures of the PH.
Methods: The proposed method designates the reduced endpoint position of fragments by superimposing the outer boundary of the premorbid bone shape on intraoperative C-arm images, taking the mirrored intact contralateral PH from the preoperative CT scan as a surrogate.
