Stabilization of pediatric diaphyseal femur fractures with flexible intramedullary nails (a technique paper).

The indications for surgical stabilization of a pediatric diaphyseal femur fracture are expanding. Children with multiple system injuries, a head injury, and/or multiple fractures have fewer local and distant complications if the femur fracture is treated operatively. Other indications include a pathological fracture in osteoporotic bone, a fracture in a child with a preexisting condition that prevents the application of a spica cast, a child older than 10 years of age, or a child less than 10 years of age who cannot be kept adequately aligned using conventional (traction/casting) methods of fracture management. Here we describe a technique of stabilizing pediatric diaphyseal femur fractures using flexible intramedullary nails (Ender). This technique can be used in children of all ages and with all patterns of diaphyseal fractures.

Lower extremity torsional deformities in children: a prospective comparison of two treatment modalities.

A prospective randomized analysis was conducted on children with lower extremity torsional deformities. Its purpose was to define the natural history of these anomalies and to determine the efficacy of treatment with a Denis-Browne splint. The natural history of pediatric lower extremity torsional deformities is to correct toward the mean of the population. The Denis-Browne splint did not alter the natural history of lower extremity torsional deformities as defined by the foot progression angle.

Ipsilateral proximal metaphyseal and flexion supracondylar humerus fractures with an associated olecranon avulsion fracture.

An ipsilateral proximal humerus fracture, "flexion" supracondylar humerus fracture, and olecranon fracture found together is a rare event. The supracondylar fracture should be reduced and percutaneously pinned before the ipsilateral upper extremity fractures are reduced. Displaced supracondylar fractures should be pinned with crossed smooth pins. Most pediatric proximal humerus and olecranon fractures can be treated closed.

Pediatric chance fracture.

A flexion-distraction injury of the first lumbar vertebrae (Chance fracture) in a child 4 years and 3 months old is discussed and the literature reviewed. Chance features are uncommon in children. This injury is seldom accompanied by a neurological deficit. Recommended treatment consists of early bed rest followed by the application of a hyperextension Risser cast.

Subacute osteomyelitis.

Subacute osteomyelitis is a chronic low-grade infection of bone characterized by a lack of systemic manifestations. The onset is insidious. Pain is the most common symptom, and has usually been present for several months before the initial evaluation. Swelling and tenderness over the area of involved bone may also be seen. Laboratory evaluation is unrevealing, with a normal white blood cell count and differential. The erythrocyte sedimentation rate may also be normal. The most common organism cultured from a subacute osteomyelitis is a staphylococcus species. Twenty-five percent of subacute bone infections are sterile. The most common manifestation of a subacute osteomyelitis in a child is a geographic lytic metaphyseal lesion (Brodie's abscess). Treatment of a culture positive infection includes surgical debridement and antibiotic therapy. A sterile abscess can be treated conservatively without antibiotics, provided the patient's symptoms are improving and the lesion is regressing radiographically.

Pseudomalignant myositis ossificans.

PMO is characterized by the following: no history of antecedent trauma, localized expanding soft tissue mass, peripheral calcification surrounding a radiolucent center on plain radiographs and CT scans, microscopic evidence of zonation, and self limited natural history.

Open pelvic fracture with vaginal laceration and diaphragmatic rupture in a child.

A case report of a 4-year-old child who sustained an unstable open pelvic fracture with a diaphragmatic rupture is presented. A strong correlation exists between rupture of the diaphragm and pelvic fractures. We note the difference between pediatric and adult pelvic fractures, and discuss late complications unique to the child with a pelvic fracture. Pelvic external fixation is faster and less morbid than other surgical treatments for unstable pelvic fractures, and therefore provides an excellent alternative to pelvic open reduction in the acute treatment of pediatric patients with multi-system injuries. If fracture reduction is incomplete following initial closed manipulation, a staged secondary open reduction can then be performed.

Hip dysplasia, subluxation, and dislocation in cerebral palsy: an arthrographic analysis.

Fifty-nine hip arthrographic roentgenograms were performed on 31 children with cerebral palsy (CP) and plain radiographic evidence of hip deformity. Five levels of hip instability were defined by the arthrographic migration index (MI). The incidence of femoral head deformation increased with an increase in MI. A new measurement, defined by the intersection of Hilgenreiner's line with a tangent drawn from the lateral cartilaginous acetabular anlage, decreased proportionally with the increase in the MI. These findings indicate that progressive deformation of the cartilaginous acetabulum and femoral head occurs during (and, in some cases, before) evolution of hip instability in patients with CP.
