The internal nasal valve incompetence (INVI) can be divided into (1) static: when the articulation between the dorsal edge of the upper lateral cartilages and the dorsal edge of the septum forms an angle less than 10 to 15 degrees and (2) dynamic: when the upper lateral cartilages collapse attracted by the negative pressure during inspiration. To correct both the static and dynamic components in severe cases of INVI, the authors propose a surgical technique consisting of upper lateral cartilages suspension over dorsal grafts; the dorsal margins of the two upper lateral cartilages are pulled dorsally and sutured together over the dorsal edge of the septum and over the dorsal-spreader grafts. The post-operative results of 12 patients affected by INVI with severe nasal obstruction were evaluated. Such a technique, which utilizes both the widening and the suspension effects, is particularly useful in the most severe cases of dynamic INVI.

High-velocity traumatic amputations of the proximal upper extremity are devastating to the patient and represent an extreme surgical challenge to the treatment team. The hand surgeon must simultaneously battle devascularization with timely microvascular anastomosis, gross contamination with meticulous debridement, and amputation with stable fixation. In restoring a functional extremity, many of these goals are in contention with each other.

Department of Orthopaedics, Division of Pediatrics and Adolescent Orthopaedic Surgery and Division of Spine Surgery, Washington University School of Medicine, St. Louis, MO.
Introduction: Since the development of pedicle screw fixation in the spine, safe placement has remained a crucial component in maximizing patient outcomes and mitigating pedicle screw-related complications. The purpose of this study is to investigate the utility of pedicle tapping in identifying pedicle breaches.
Methods: A pediatric spine surgery database was queried to identify a consecutive series of patients who underwent spinal deformity surgery utilizing pedicle screw fixation between May 2019 and October 2022.
Autogenous bone ring augmentation and simultaneous implant placement in the atrophic posterior maxilla: A case report.

Introduction And Importance: Restoring lost teeth in the posterior atrophic maxilla presents a significant challenge due to insufficient bone volume for implant placement. Simultaneous implant placement during lateral sinus lift is often considered, but the decision is typically based on the amount of existing bone. The aim of this study was to investigate the feasibility of simultaneous implant placement and maxillary sinus floor augmentation in the atrophic posterior maxilla using autogenous bone ring.
