Excision of Rudimentary Preaxial Polydactyly of the Hand with Use of Electrocautery.

Background: Suture ligation has been used widely for the treatment of rudimentary type extra digits, but several complications related to this treatment have been reported. The purpose of this study was to describe a new technique for excision of rudimentary preaxial polydactyly of the hand using electrocautery and assess its clinical outcomes.

Methods: The authors performed a retrospective study of 34 thumbs (32 patients) that had undergone excision of rudimentary preaxial polydactyly using electrocautery under local anesthesia.

Association Between Vertebral Rotation Pattern and Curve Morphology in Adolescent Idiopathic Scoliosis.

Objectives: Although rotation is an important aspect of pathogenesis of adolescent idiopathic scoliosis (AIS), there are no studies demonstrating rotation pattern by directly measuring rotation angle in computed tomography (CT) images. The present retrospective comparative radiographic study was conducted to evaluate the rotation pattern in AIS and its relation to curve morphology and Lenke classification.

Methods: The study included 245 patients diagnosed with AIS and evaluated with a preoperative CT scan.

Disc Wedge and Vertebral Body Tilt Angle Below Lower Instrumented Vertebra After Posterior Correction and Fusion in Patients With a Structural Thoracolumbar/Lumbar Curve: A Minimum 5-Year Follow-up.

Study Design: A retrospective cohort study.

Objective: The purpose of this study was to evaluate the stability of remained lumbar curve by the review of serial changes in L3/L4 disc wedge and L4 body tilt angle in patients with idiopathic scoliosis who underwent posterior-only fusion to L3 lower instrumented vertebra (LIV) for the correction of structural thoracolumbar/lumbar (TL/L) curve for a minimum 5-year follow-up.

Summary Of Background Data: There has been some debate in the selection of L3 or L4 as the LIV for the correction of structural TL/L curve.
