Resultados de tratamento cirúrgico da pseudoartrose de fratura diafisária do úmero com placa de compressão dinâmica e enxerto de osso esponjoso

Abstract

ObjectiveWe evaluated the treatment of nonunion of humeral shaft fracture with dynamic compression plate from January 2002 to December 2009.MethodsTwenty-two patients were treated over the study period. Trauma was the predominant cause of injury in 86.4% of the patients.ResultsNonunion was atrophic in 81.8% and hypertrophic in 18.2% of the individuals. There was a primary injury of the radial nerve in 27.3% of the patients. All the participants had closed fracture at presentation, and 81.2% had received previous treatment from traditional bone setters and 18.8% had failure of the conservative cast management. The average time to healing was 16 weeks. Previous treatment from traditional bone setters significantly affected the time to fracture healing (p<0.05). All fractures had successful union.ConclusionIt was concluded that dynamic compression plating remains an effective treatment option for nonunion of humeral shaft fracture. Level of Evidence III, Retrospective study.

Analysis of fracture healing in osteopenic bone caused by disuse: experimental study

“…There are two methods for treating fractures: conservative (using a plaster cast, splint, and orthosis) and surgical (using plates, screws, Kirschner wire, and percutaneous pins) ( 7 , 26 ). Immobilization is crucial for bone healing because a minimum cortical contact is required for the bone to join properly ( 7 ); based on this principle, the best treatment method can be chosen according to each fracture’s particular characteristics.…”
