Musculoskeletal abnormalities and ichthyosis.

Musculoskeletal abnormalities and the associated findings of ichthyosis were seen in three patients between 1972 and 1975. Review of the literature revealed that musculoskeletal abnormalities had previously been recognized in patients with ichthyosis, but not emphasized because of the more frequent and profound neurological abnormalities. Interestingly, our patients had no neurological abnormalities. Ichthyotics should have thorough musculoskeletal as well as neurological and dermatological examinations.

Congenital bipartite scaphoid--fact or fiction?

Whether there is such a condition as congenital bipartite scaphoid has long been debated. Five cases that fulfill the established criteria are presented, supplemented by a review of roentgenograms of 17,439 hands in which no case of bipartite scaphoid was detected. Serial sections of 196 fetal hands also failed to reveal any evidence of bipartite development of the scaphoid. We concluded that bipartite scaphoid is of traumatic origin and should be treated accordingly.

Open reduction and internal fixation of forearm fractures in children.

We retrospectively reviewed 16 children younger than 13 years with 17 fractures of the shafts of the radius or ulna or both who had undergone an open reduction-internal fixation (ORIF). ORIF was performed when a closed reduction was deemed unacceptable in 14 radius fractures and for three unstable open fractures of the radius. The average age was 9.4 +/- 2.3 years (range, 5.0-12.5). Of the 14 fractures with an unacceptable closed reduction, soft-tissue interposition was encountered in seven. Fixation was secured by plates and screws, percutaneous Steinmann pins, or intramedullary Steinmann pins. There were no delayed unions or nonunions, no infections, and no neurovascular injuries. The average follow-up was 12.3 months; all 17 fractures had excellent results (forearm rotation loss of < 10 degrees). Our study indicates that excellent results can be expected with no increased risk of complications if the treating physician elects to proceed with an ORIF in a pediatric forearm fracture with proper indications.

CT findings in distal radioulnar dislocation.

Dislocation of the distal radioulnar joint may occur in association with fractures of the distal radius. As an isolated entity, however, it is frequently overlooked, resulting in prolonged pain and significant disability. Our case illustrates the need for careful clinical evaluation as well as the utilization of conventional radiography and CT.

Ulnar nerve palsy following rotational osteotomy of congenital radioulnar synostosis.

Two successive cases of ulnar nerve palsy following rotational osteotomy through a congenital radioulnar synostosis are described. Entrapment of the ulnar nerve by the fascia connecting the two heads of the flexor carpi ulnaris was documented in one patient. Recommendations to avoid this complication include shortening of the forearm at the osteotomy site and the release of unyielding soft tissue restraints. Rotational osteotomy at the distal radial metaphysis may provide a safe, alternative approach in the surgical management of this difficult problem.

Eastern massasauga rattlesnake bites.

The Eastern massasauga rattlesnake is native to many Midwestern states. Although this rattlesnake is smaller in size than many other pit vipers, envenomation can still produce significant morbidity, particularly in children. Children bitten by Eastern massasauga rattlesnakes appear to do well with treatment programs consisting primarily of antivenom and blood component replacement.

Surgical management of the severely multiply handicapped individual.

Thirty-four surgical procedures were performed over a 12-year period on a select population of severely multiply handicapped individuals. Heel cord lengthening, hamstring and adductor releases, as well as selected osteotomies, tenotomies, and arthrodeses (both wrist and foot) were performed. The objectives were improvement in sitting posture, care, and comfort. Independent evaluations of active function, passive function, cosmesis, self-esteem, limb posture, and ease of dressing and hygiene were assessed. Significant improvement was generally noted. No patient was made worse. Selected procedures in the severely multiply handicapped individual have a definite place in patient management.
