BACKGROUND Clavicle fractures are common injuries of the shoulder girdle and occasionally result in nonunion or symptomatic malunion. When present, these chronic injuries can result in considerable shoulder dysfunction. A number of surgical techniques have been described for the management of these injuries. Current literature suggests that supplemental bone grafting may not be necessary in all...

PURPOSE To review the outcomes of 102 consecutive patients who underwent fixation for nonunion of extremities. METHODS Medical records of 71 men and 31 women aged 16 to 82 (mean, 45; standard deviation [SD], 19) years who underwent fixation for nonunion of the upper (n=31) and lower (n=71) extremities were reviewed. The nonunion types included oligotrophic (n=47), hypertrophic (n=22), atrophi...

Orthopedic surgeons have long been troubled by cases involving nonunion of fractured bones. This study aimed to enhance bone union by cell sheet transplantation of mesenchymal stem cells. A nonunion model was made in rat femur, and rat bone marrow cells were cultured in medium containing dexamethasone and ascorbic acid phosphate to create a cell sheet that could be scraped off as a single sheet...

Background Scaphoid fractures are common carpal fractures that are often misdiagnosed as wrist sprains and may go on to nonunion. The location of the fracture site may influence the stability of scaphoid nonunions. Purpose To determine whether the stability of a scaphoid nonunion depends upon the fracture's location, we tested the hypothesis that a simulated fracture distal to the apex of the s...

BACKGROUND There are many methods for treating femoral shaft aseptic nonunions of which exchange nailing is the simplest technique. However, the reported success rate varies. Therefore, a prospective study was conducted to further clarify the role of exchange nailing. METHODS From October 1994 through December 1999, 40 femoral shaft aseptic nonunions in 39 patients were treated using exchange...

BACKGROUND Delayed union and nonunion are common complications in atypical femoral fractures (AFFs) despite having good fracture fixation. Demineralized bone matrix (DBM) is a successfully proven method for enhancing fracture healing of the long bone fracture and nonunion and should be used in AFFs. This study aimed to compare the outcome after subtrochanteric AFFs (ST-AFFs) fixation with and w...

Nonunion of fractures or osteotomies in the pediatric population is rare. The gold standard for the treatment of nonunions involves harvesting autologous iliac crest bone graft and sometimes internal fixation, which are invasive procedures. The purpose of this study was to evaluate the effectiveness of pulsed electromagnetic field on a non-united fracture or osteotomy in the pediatric populatio...

A 4-year-old, intact male crossbreed dog, weighing 27 kg, was referred for the treatment of a nonunion fracture. The radiographs revealed displacement of the radius and ulna bone fracture fragment and a sclerotic fracture end of the radius. Autologous adipose derived stem cells (ADSCs) were isolated and expanded ex vivo in a culture. The ADSCs (3.2 × 107 cells) were seeded on a composition scaf...

The failure of an osseous fracture to heal, or the development of a nonunion, is common; however, current diagnostic measures lack the capability of early and reliable detection of such events. Analyses of radiographic imaging and clinical examination, in combination, remain the gold standard for diagnosis; however, these methods are not reliable for early detection. Delayed diagnosis of a nonu...
