Pediatric tibial eminence fracture treatment: A case series using a bioabsorbable screw.

Background: Pediatric tibial eminence fractures constitute a complex injury with multiple treatment options. We have described a technique that combines direct visualization through an open approach and stable fixation using a bioabsorbable screw. The purpose of this study is to describe our surgical technique for tibial eminence fractures and to compare the radiographic and functional outcomes to previous open or arthroscopic methods.

Pediatric Tenosynovial Giant Cell Tumor of the Flexor Hallucis Longus Tendon Sheath: A Case Report.

Case: An otherwise healthy 13-year-old girl presented with a firm nodule on the plantar right forefoot that was tender after cheerleading. Initial workup was unremarkable, but magnetic resonance imaging revealed a multilobulated mass surrounding the flexor hallucis longus tendon. Surgical resection revealed a tenosynovial mass without tendon infiltration.

Pediatric Olecranon Osteochondral Flap Fractures With Subtle Radiographic Abnormality.

Pediatric olecranon osteochondral flap fractures are shear injuries of the humeroulnar joint with elevation of an articular cartilaginous flap from the subchondral bone of the olecranon articular surface. All previously reported cases included an osteochondral flap containing the coronoid, with varying imaging and fixation methods used. We treated 2 pediatric patients with this injury.

Distal Tibial Chondroblastoma With Intra-articular Penetration Treated With Gelatin Foam Sponge and Bone Grafting.

A 14-year-old boy presented with sharp left ankle pain for 1.5 years. Evaluation showed an irregular lytic lesion with surrounding sclerosis (diameter, 1.

Transgluteal Approach for Drainage of Obturator Internus Abscess in Pediatric Patients.

Background: Of the locations of peripelvic pyomyositis, infection of the obturator musculature poses a difficult challenge for operative drainage. The anatomic location of the obturator muscles, especially the obturator internus, complicates operative debridement as the surgical approach must safely bypass a large number of neurovascular structures. Realizing the challenges and risks of approaches to the obturator musculature, the purpose of our study was to review a novel, yet simple, posterior approach to the obturator internus.

Quick monitoring of pozzolanic reactivity of waste ashes.

This article proposes a quick method of monitoring for pozzolanic reactivity of waste ashes by investigating the electrical conductivity of the suspension at an elevated temperature. This suspension is obtained by mixing tested pozzolan with an ordinary Portland cement (OPC) solution produced by mixing ordinary Portland cement with water. For comparison, silica fume, metakaolin, rice husk ash and river sand - whose pozzolanic reactivities range from reactive to inert - were used in the experimental investigation.

Multifocal variant of heterotopic ossification.

In this case report, we present a 25 year follow-up of a single patient with a previously undescribed multifocal variant of heterotopic ossification. The patient presented with multiple occurrences of lesions similar to myositis ossificans atraumatica as well as some lesions resembling exostoses/osteochondromas. Several images and histological sections show the range of appearances and locations of her somewhat disparate lesions, including an exostosis with intraspinal extension.

A bullet-sired bone cyst.

Random gunfire deposited a bullet in the proximal tibial metaphysis of a 9-year-old girl. The wound was not incapacitating and was treated conservatively. Within 17 months, soreness developed in the proximal leg, and radiography revealed a large unicameral cyst within which the bullet freely tumbled.

Cardiofaciocutaneous syndrome (CFC) with congenital peripheral neuropathy and nonorganic malnutrition: an autopsy study.

Many phenotypic manifestations have been reported in cardiofaciocutaneous (CFC) syndrome, but none, to date, are pathognomonic or obligatory. Previous histopathological studies reported findings in skin and hair; no autopsy studies have been published. We report the clinical and autopsy findings of a 7-year-old boy with severe CFC syndrome and malnutrition of psychosocial origin.

Acute compartment syndrome after rupture of the medial head of the gastrocnemius muscle.

Rupture of the gastrocnemius muscle is an uncommon injury, with most cases occurring in athletically active individuals. The presentation of a gastrocnemius rupture is the acute onset of calf pain and subsequent ecchymosis. Most of these injuries can be treated symptomatically with good results.

An irreducible knee dislocation: a case report.

An 8-year-old man presented after sustaining an injury during a fall. A closed reduction attempt failed, and after several tests, an open reduction was performed. With posterolateral dislocation of the knee, there can be anterior cruciate ligament, posterior cruciate ligament, and medial collateral ligament disruption.

Tumoral calcinosis in an infant.

We report tumoral calcinosis, an uncommon disease of uncertain origin, in an infant-only the sixth instance of the disease reported in this age group. The radiologic features are typical as illustrated by three modalities. The clinical, radiologic and pathologic features are discussed along with comments concerning possible etiologies and management.

Ultrasonography in the management of painful hips in children.

The decision to aspirate a painful hip joint is often based on history, physical, and laboratory findings. The purpose of this study is to determine whether ultrasound is helpful in making decisions to aspirate a painful hip joint in children. The anterior capsular distance was determined in 10 children with painful or irritable hips.

Ultrasonography in the management of developmental dysplasia of the hip (DDH).

Real time ultrasonography, according to the method of Graf, was performed on 113 infant hips because of abnormal physical findings (ranging from hip clicks to frank dislocation). Three parameters were measured on the standard coronal images: alpha and beta angles of Graf and the d/D ratio of Morin. Results indicated that the presence of hip clicks (88 hips) in general is a benign condition and not associated with abnormal anatomy.

Intramedullary screw fixation of lateral malleolus fractures.

A biomechanical evaluation of intramedullary versus buttress plate and lag screw fixation of lateral malleolus fractures is combined with a clinical evaluation of 44 patients with lateral malleolus fractures who underwent intramedullary screw fixation. The biomechanical study was performed in experimentally produced, Weber B, supination-eversion ankle fractures. The fractures were fixed with one of the two above fixation methods and then placed under a torsional load to failure.

Percutaneous intramedullary fixation of lateral malleolus fractures: technique and report of early results.

Twenty-four patients with Weber B and low Weber C displaced lateral malleolus fractures who underwent closed reduction and percutaneous internal fixation with an intramedullary, fully threaded, self-tapping screw were retrospectively reviewed. Nineteen of these patients were followed for an average of 63.4 weeks.

Chondromyxoid fibroma.

Chondromyxoid fibroma (CMF) is the least common cartilage-producing tumor. In Dahlin and Unni's series of 8,542 bone tumors, 39 of which were CMF, none were found in the femoral shaft. In this case, a CMF in the femoral shaft presented initially as a pathologic fracture.

Superficial temporal artery laceration. A complication of skull tong traction.

Complications associated with the use of skull tongs are not uncommon. We report a case of superficial temporal artery injury as a complication of Gardner-Wells tong application. Chronic recurrent episodes of pulsatile bleeding from the pin site necessitated arterial ligation to control the bleeding.

Hereditary spastic paraplegia.

Hereditary spastic paraplegia (HSP) is a genetically determined condition that is often confused with, and misdiagnosed as, spastic diplegic cerebral palsy. Both autosomal dominant and recessive forms have been reported. We present three index patients in a single family with this disease.
