Evaluation of the child with a bone or soft-tissue neoplasm.

The prebiopsy evaluation of a child with a musculoskeletal neoplasm is the cornerstone for all subsequent treatment. A better understanding of the natural history of pediatric musculoskeletal tumors and an explosion in the development of sensitive new imaging modalities have significantly advanced the care of the child with a musculoskeletal pathologic condition. This article details the prebiopsy clinical and radiographic evaluation of the child or adolescent with a musculoskeletal neoplasm.

Orthopedic manifestations of acute pediatric leukemia.

The variety and distribution of skeletal lesions in children with acute lymphoblastic leukemia is rarely seen in other diseases. Skeletal radiographic changes that can occur in a child with acute leukemia include diffuse osteopenia, metaphyseal bands, periosteal new bone formation, geographic osteolysis, osteosclerosis, mixed osteolysis and sclerosis, and permeative destruction. It is important for orthopedic surgeons to recognize the skeletal manifestations of acute leukemia of childhood because the physician who initially evaluates the child will often be an orthopedic surgeon, and a delay in diagnosis has an adverse affect on survival.

Undiagnosed fractures in severely injured children and young adults. Identification with technetium imaging.

A whole-body bone scan was performed to search for undetected fractures in forty-eight patients who had multiple injuries or a head injury, or both, and who were less than twenty-two years old. The study took place from January 1991 to July 1992. Radiographs had been made of all areas of suspected skeletal trauma at the time of admission. Follow-up plain radiographs were made of all areas where unexpected abnormal tracer activity was noted. Forty-two of these areas were noted in eighteen skeletally immature patients and fifty-two, in twelve skeletally mature patients. Nineteen previously unrecognized fractures were identified in the subsequent radiographic analysis. Four skeletally immature and two skeletally mature patients had an alteration in treatment on the basis of the identification of a previously undiagnosed injury. Each of these six patients had a cast applied. A fracture was identified three weeks or more after the injury in two skeletally mature patients. These fractures would have been treated (one with a cast and the other with open reduction and internal fixation) if they had been diagnosed earlier. We believe that this analysis demonstrates the usefulness of technetium radionucleotide bone-imaging, as an adjuvant to the orthopaedic examination, in the identification of undiagnosed musculoskeletal injuries in a patient who is less that twenty-two years old and who has sustained a head injury or multiple injuries, or both.

Operative stabilization of pediatric femur fractures.

Femur fractures represent approximately 1.7% of all pediatric bony injuries. Most femur fractures were treated nonoperatively prior to the early 1980s. Recent refinements in the operative techniques used to treat pediatric femur fracture have led to a reduction in the use of traction and casting treatment methods.

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.
