Pediatric spondylolysis and spondylolisthesis present with a wide spectrum of pathology and clinical findings, including back pain, leg pain, crouch gait, or neurological deficit. The treatment of spondylolysis alone is typically conservative with bracing, non-steroidal anti-inflammatory drug, and activity restriction, but refractory pain can be successfully surgically managed with intralaminar compression screw, wires, or pedicle screws with rods and laminar hook constructs. The treatment of dysplastic spondylolisthesis is aggressive to prevent neurological deficit, whereas even high-grade isthmic slips can be treated safely with nonoperative measures if no significant neurological deficits are present...

We present a novel technique for the surgical management of sizeable medial upper eyelid colobomas that entails advancement of an ipsilateral upper lid flap sustained by a levator aponeurosis-Müller-conjunctiva pedicle and combined with a lateral semicircular flap from the affected lid. The technique was used in 4 consecutive pediatric patients of mean age 21.2 months and mean coloboma size 12.3 mm and resulted in sufficient cornea protection, rapid rehabilitation, and satisfying cosmesis.

Prasad Krishnan, Krishnamurthy Sridhar
Traditional teaching describes two types of bone flaps in craniotomies - 'free bone flap' and osteoplastic craniotomies. While in the former, the entire bone flap devoid of soft tissue attachments is removed, in the latter the bone flap that is turned is hinged on a pedicle of temporalis muscle with the aim of retaining its vascular supply. We describe a variant of the latter in 13 pediatric patients in whom the lower margin of the craniotomy was above the attachment of the temporalis muscle and where the bone flap was lifted with all the layers of the scalp including the skin and galea, highlighting the thought process behind its performance and the advantages of the same...

BACKGROUND: Large congenital melanocytic nevi entail significant medical and cosmetic ramifications for patients and families. Reconstruction is a challenging endeavor, especially when the lesion is present on the limbs. The literature describes various methods by which a plastic surgeon can address reconstruction; yet, to date, there has been no series describing a method that provides consistent results with low complication rates. In this study, we describe our surgical technique for reconstruction of the upper extremity after excision of large circumferential CNM with a pre-expanded bi-pedicled flap, namely the "sleeve" flap...

BACKGROUND CONTEXT: Many etiologies can lead to atlantoaxial subluxaion. In Grisel syndrome (GS), this subluxation occurs spontaneously after inflammatory processes of the head and neck. Diagnosis is typically based on clinical history and a strong suspicion of this syndrome. Nonsurgical treatment most often resolves the symptoms; however, in some cases surgical treatment is necessary to repair the subluxation. Various surgical techniques and instrumentation systems have been used to treat atlantoaxial subluxation, although there is no consensus regarding the best treatment method for the pediatric population...

A 15-year-old patient harmed himself upon firing a shotgun that he was carrying when he slipped and fell, causing a destructive wound in the right arm with a medial entry hole and a posterolateral exit hole. The biceps, coracobrachialis, triceps, deltoids, skin cover, and humerus were injured; however, the blood vessels and major nerves of the area were surprisingly not affected. The residual skin muscle defect after debridements was 16 × 5 cm medially and posteriorly, and the bone loss was 7 cm. The wound was reconstructed during a single surgery with a free fibula flap and a pedicled flap of latissimus dorsi...

BACKGROUND: Pediatric spine trauma often results from high-energy mechanisms. Despite differences in healing potential, comorbidities, and length of remaining life, treatment is frequently based on adult criteria; ligamentous injuries are fused and bony injuries are treated accordingly. In this study, we present short-term results of a select group of adolescent patients treated using percutaneous pedicle screw instrumentation without fusion. METHODS: An IRB-approved retrospective review was performed at a level 1 pediatric trauma center for thoracolumbar spine fractures treated by percutaneous pedicle screw instrumentation...

BACKGROUND: Intraoperative C-arm fluoroscopy and low-dose O-arm are both reasonable means to assist in screw placement for idiopathic scoliosis surgery. Both using pediatric low-dose O-arm settings and minimizing the number of radiographs during C-arm fluoroscopy guidance decrease patient radiation exposure and its deleterious biological effect that may be associated with cancer risk. We hypothesized that the radiation dose for C-arm-guided fluoroscopy is no less than low-dose O-arm scanning for placement of pedicle screws...

INTRODUCTION: Idiopathic scoliosis is the lateral curvature of the spinal column greater than 10° with no established etiology. In skeletally immature pediatric patients, risk of progression is associated with the severity of curvature. It has been estimated that this risk is nearly 90% for patients with curvatures exceeding 50°, and this is typically the severity at which surgical management is indicated. Current surgical techniques rely heavily on posterior instrumentation with pedicle screw systems...

STUDY DESIGN: Case report. OBJECTIVE: To report a case of progressive pain and paraparesis secondary to metallosis four years after a pediatric posterior spinal fusion (PSF). SUMMARY OF BACKGROUND DATA: Metallosis as a late complication of pediatric spinal surgery is rarely reported. Myelographic computed tomography (CT) can be helpful in establishing the diagnosis. The use of serum chromium levels as a means of definitive diagnosis has been suggested, but has only been reported retrospectively...

This is a retrospective review of pedicle screw placement in adolescent idiopathic scoliosis (AIS) patients under 18 years of age who underwent robot-assisted corrective surgery. Our primary objective was to characterize the accuracy of pedicle screw placement with evaluation by computed tomography (CT) after robot-assisted surgery in AIS patients. Screw malposition is the most frequent complication of pedicle screw placement and is more frequent in AIS. Given the potential for serious complications, the need for improved accuracy of screw placement has spurred multiple innovations including robot-assisted guidance devices...

Severe motorcycle spoke injuries of the heel lead to Achilles tendon defects, calcaneal tubercle exposure or loss, and overlying soft tissue defects, which are challenging to treat. Given the special physiological and developmental characteristics of children, severe spoke injuries of the heel in children are especially troublesome.We report details of 31 cases of severe motorcycle spoke injuries of the heel in children. The reconstruction timing depended on the time since injury, systematic conditions, and concurrent injuries...

Anterior release and fusion is sometimes required in pediatric patients with thoracic scoliosis. Typically, a formal anterior approach is performed through open thoracotomy or video-assisted thoracoscopic surgery. The authors recently developed a technique for anterior release and fusion in thoracic scoliosis referred to as "posterior convex release and interbody fusion" (PCRIF). This technique is performed via the posterior-only approach typically used for posterior instrumentation and fusion and thus avoids a formal anterior approach...

BACKGROUND: Pediatric scar contractures in rapidly-growing regions require timely correction. Compared to flaps, skin grafts are characterized by scarring and retraction. More complex reconstructions are especially challenging in pediatric cases. Pedicled fasciocutaneous flaps are simple, durable, and able grow with the patient. METHODS: A series of 22 pediatric burn scar cases, with an average age of 6years, underwent treatment with pedicled fasciocutaneous flaps...
