Safe Optimal Tear Drop View for Spinopelvic Fixation Using a Three-Dimensional Reconstruction Model of the Pelvis.

Background: Spinopelvic fixation (SPF) has been a challenge for surgeons despite the advancements in instruments and surgical techniques. C-arm fluoroscopy-guided SPF is a widely used safe technique that utilizes the tear drop view. The tear drop view is an image of the corridor from the posterior superior iliac spine to the anterior inferior iliac spine (AIIS) of the pelvis.

Reconstruction of the weight-bearing heel with nonsensate reverse sural artery flaps.

Background: The reverse sural artery flap (RSAF) is widely used to reconstruct foot and ankle defects. Although it is commonly used in a nonsensate type, there has been controversy as to whether it provides sufficient stability and durability when applied to weight-bearing heels. The aim of this study was to evaluate patient outcomes after weight-bearing heel coverage using a nonsensate RSAF.
