Multicenter validation of a surgical planning tool for lumbar vertebral body tethering simulating growth modulation over 2 years.

Purpose: Vertebral body tethering (VBT) for lumbar curves may have wider application than for thoracic curves due to greater growth potential than thoracic spine and benefits of preserved flexibility. Predicting long-term correction remains challenging, with high revision rates and complications (14-32%) including under-/over-correction, tether breakage, adding-on. This study aimed to validate a planning tool for lumbar VBT using a patient-specific finite element model (FEM) integrating mechanobiological growth modulation as a function of preoperative skeletal maturity.

Drain options after vertebral body tethering.

Purpose: Since the introduction of vertebral body tethering (VBT) for adolescent idiopathic scoliosis (AIS), a variety of post-operative chest drainage systems have been utilized. Most surgeons use formal chest tubes with a Pleur-evac, while others use smaller bulb suction drains (e.g.

Hip Impingement after Anterior Inferior Iliac Spine Avulsion Fractures: A Case Report with Review of the Literature.

Avulsion fractures of the anterior inferior iliac spine (AIIS) are rare injuries in adolescent athletes. We present a case of a 15-year-old male who sustained an avulsion injury to his right AIIS when kicking a soccer ball. The patient had chronic pain and extra-articular subspinal impingement leading to decreased hip flexion and rotation.

A study of the cutaneous nerves encountered during thoracoplasty.

Study Design: Ten cadavers were dissected to describe the cutaneous branches of the dorsal rami nerves that should be identified and protected throughout the thoracoplasty procedure.

Objective: To identify the anatomic distribution of the cutaneous branches of the dorsal rami in the thoracic spine.

Summary Of Background Data: The last anatomic description of cutaneous branches of the dorsal rami nerves dates back to the early 1900s.
