Pediatric Hand Injuries Requiring Closed Reduction at a Tertiary Pediatric Care Center

Background: Hand fractures and dislocations are common injuries in the pediatric population. This study aims to characterize the pediatric hand injuries that required closed reduction and identify those that required multiple reduction attempts. Methods: A retrospective cohort study was carried out in patients younger than 18 years of age with hand fractures or dislocations who underwent closed reduction in the emergency department (ED). Patients who ultimately required surgical reduction and fixation were not included. Results: Of the 310 hand injuries identified, 148 (114 fractures and 34 dislocations) underwent closed reduction in the ED; 7.4% of those required repeat reduction. Hand injuries that most often required repeat reduction included metacarpophalangeal joint dislocations (20.0%) and proximal phalanx neck (16.7%), metacarpal shaft (15.4%), metacarpal neck (6.2%), and proximal phalanx base (5.6%) fractures. No modifiable risk factors predicting the need for repeat reduction were identified. Conclusions: Some pediatric hand injuries are more likely to require repeat closed reduction by a hand surgeon. This retrospective study is the first step toward quality improvement as it provides opportunities for further research into the factors contributing to reductions that are unsuccessful at the first attempt. Identification of these factors and implementation of quality improvement measures are necessary to ensure the effective treatment of all pediatric hand injuries.     

Anatomic study of the pre- and neonatal hip. Physiopathologic considerations on dysplasia and congenital dislocation of the hip

Summary Therapeutic success in dysplasia and congenital dislocation of the hip depends on an early diagnosis. The physiopathology remains very debatable and several concepts are propounded. For a better physiopathologic understanding, the authors have carried out a study of the morphology and development of 22 pre- and neonatal hips. At first, the acetabulum is cartilaginous and distorted by the moving femoral head; this acetabulum is histologicaly affected by the femoral pressure.The pathologic hip is characterized by defective posterior bony coverage of the femoral head by the acetabulum. The acetabulum ossifies during the 3 months following birth, forming a cup-like cavity under the pressure of the femoral head. Therefore, neonatal screening tests such as sonography must take place in the first weeks of life.

Étude anatomique de la hanche antéet néonatale. Réflexions sur la physiopathologie des dysplasies et luxations congénitales de la hanche

Résumé Le succès du traitement des dysplasies et luxations congénitales de hanche est lié à la précocité du diagnostic. La physiopathologie de ces affections reste discutée et plusieurs conceptions ont pu être proposées. Les auteurs ont réalisé une étude structurale et évolutive de 22 hanches anté et néonatales afin de mieux comprendre cette physiopathologie. Dans les périodes anté- et néonatale, l'acétabulum est cartilagineux, déformable sous l'action d'une tête fémorale en mouvement et il est le siège de remainements histologiques dépendant de la pression exercée par l'épiphyse fémorale. L'ossification de l'acétabulum s'effectue lors du ler trimestre postnatal, construisant la cavité articulaire sous l'effet de la pression de la tête du fémur. Dysplasies et luxations apparaissent comme un défaut de couverture postéro-supérieure de l'épiphyse fémorale par l'acétabulum. Le dépistage d'anomalies, notamment par l'échographie, devra donc être réalisé dans les premières semaines de la vie.

     

Humeruskopfresektion als therapie bei oberarmkopftrümmerfrakturen —ergebnisse

Zusammenfassung Proximale Humerusfrakturen gehö-ren zu den häufigen Verletzungen des ä1teren Menschen. Gering dislozierte Brüche können mit gutem Erfolg konservativ behandelt werden. Therapeutische Schwierigkeiten bereiten vor allem dislozierte Mehrfragment- oder Trümmerfrakturen des Oberarmkopfes. Im Zeitraum von 1970–1988 wurde in unserer Klinik in dieser Situation bei 8 Patienten eine Resektion des Humeruskopfes durchgeführt. 6 Patienten konnten bei einer mittleren Beobachtungszeit von 69 Monaten nachuntersucht werden. Alle Patienten wiesen postoperativ eine erhebliche Bewegungseinscänkung im betroffenen Schultergelenk auf. Die durchschnittliche Abduktion betrug 60° (40–80dg), die Anteflexion 60° (40–80°) bei einer mittleren AuBenrotation von 17° (5–30°) und Innenrotation von 48° (5–90°). Eine Patientin war postoperativ schmerzfrei, 2 weitere verspürten nächtliche Schmerzen, während die übrigen 3 Patienten fiber eine unterschiedliche Schmerzsymptomatik klagten. Dennoch waren 5 der 6 Patienten mit dem Operationsergebnis zufrieden, eine Patientin bewertete das Resultat mit gut.

Resection of the humeral head in cases of head-splitting humeral fractures — results

Summary Proximal humeral fractures are frequent injuries in older patients. Most of these fractures respond satisfactorily to conservative treatment. Problems arise in cases of four-part displacements and in head-splitting fractures with massive defects in the articular surface. Between 1970 to 1988 eight patients were treated in our clinic in this situation by resection of the humeral head. 6 patients could be followed-up for an average of 69 months. Postoperative findings showed a restricted range of motion in all operated shoulders. The average abduction of the arm was 6° (40-80°) and elevation 60° (40–80°). The patients showed a mean external rotation of 17° (5–30°) and an internal rotation of 48° (5–90°). Only one patient was painless, 2 patients had pain during the night, and 3 patients suffered from various pain symptoms. Nevertheless 5 of 6 patients assessed the result as satisfactory and one patient as good.

THE OPERATIVE TREATMENT OF SPINAL FRACTURE-DISLOCATION WITHOUT NEUROLOGIC DEFICITS

Objective. To evaluate the results of operative treatment of spinal fracture-dislocation without neumlogic deficits. Metods. Eighteen patients with spinal fracture-dislocation were neurologically intact at the time of injury, and all were treated operatively. The fracture sites were:8 cases in cervical spine, 3 cases in thoracic spine, and 7 cases in lumbar spine. Eight patients with cervical injuries had variant degrees of forward slide and kyphotic deformity. Of the 10 thoracic and lumbar fractures, one had lateral dislocation, 4 cases with kyphotic deformities, 5 cases withspinal canal compromise averaged 50% (ranging from 40% to 70% ).Results. The aveiage period of follow-up was 4.4 years with a range of 11 months to 13 years. All the patients returned to full-time work. No patient developed neurologic deterioration. Kyphotic deformity was corrected in the 4 cases, and no progressive kyphosis was noted. There was no operation-related complication. The averaged post-opera-five hospitalization time was 13 days. Conclusions. Despite the rare incidence of spinal fracture-dislocation without neurologic deficits, we suggested that kind of fracture be considered unstable fracture because of its potential risk of delayed neurologic deterioration and kyphotic deformity, and be treated operatively to restore the sagittal alignment and the stability of the spine.     

Lumbosacral fracture dislocation in a lumberjack

Summary Lumberjack fractures normally occur in the thoracic and upper lumbar spine as a result of hyperextension and shear. This case, however, involves a lumberjack who suffered a lumbosacral fracture dislocation without neurological deficits, which occurred as the result of shear and hyperflexion. Due to the high degree of instability of this lesion, the treatment consisted of dorsoventral fusion with instrumentation.

Cost of treatment of congenital dislocation of the hip

Early treatment for congenital dislocation of the hip is usually simple and inexpensive. However, if the disease is not detected by 6 months of age, treatment is often complicated and expensive. We evaluated the potential cost-saving of screening, by examining the costs in 36 late cases born in 1980 and found an average cost of pounds 6,674 per case for treatment to this date. This amount could justifiably be spent on each case detected in an effective screening programme.
