Meta AnalysisThe use of calcium phosphate bone cement in fracture treatment. A meta-analysis of randomized trials.
Available options to fill fracture voids include autogenous bone, allograft bone, and synthetic bone materials. The objective of this meta-analysis was to determine whether the use of calcium phosphate bone cement improves clinical and radiographic outcomes and reduces fracture complications as compared with conventional treatment (with or without autogenous bone graft) for the treatment of fractures of the appendicular skeleton in adult patients. ⋯ The use of calcium phosphate bone cement for the treatment of fractures in adult patients is associated with a lower prevalence of pain at the fracture site in comparison with the rate in controls (patients managed with no graft material). Loss of fracture reduction is also decreased in comparison with that in patients managed with autogenous bone graft.

Comparative StudyComplications of titanium and stainless steel elastic nail fixation of pediatric femoral fractures.
In vitro mechanical studies have demonstrated equal or superior fixation of pediatric femoral fractures with use of titanium elastic nails as compared with stainless steel elastic nails, and the biomechanical properties of titanium are often considered to be superior to those of stainless steel for intramedullary fracture fixation. We are not aware of any clinical studies in the literature that have directly compared stainless steel and titanium elastic nails for the fixation of pediatric femoral fractures. The purpose of the present study was to compare the complications associated with the use of similarly designed titanium and stainless steel elastic nails for the fixation of pediatric femoral fractures. ⋯ Our results indicate that the less expensive stainless steel elastic nails are clinically superior to titanium nails for pediatric femoral fixation primarily because of a much lower rate of malunion.

Randomized Controlled Trial Comparative StudyNonoperative compared with operative treatment of acute scaphoid fractures. A randomized clinical trial.
Traditionally, acute nondisplaced scaphoid fractures have been treated nonoperatively in a cast, and the expected union rate approaches 90%. Internal fixation of nondisplaced scaphoid fractures has increased in popularity, and a union rate of 100% has been reported. The growing trend is to recommend internal fixation for the majority of acute scaphoid fractures. The true long-term benefits of this more complicated treatment modality have not yet been determined in randomized controlled trials. The purpose of this study was to compare the long-term results of operative fixation of acute scaphoid fractures with those of nonoperative treatment. ⋯ This study did not demonstrate a true long-term benefit of internal fixation, compared with nonoperative treatment, for acute nondisplaced or minimally displaced scaphoid fractures. The long-term risks of surgery should be considered when recommending operative treatment.

Open reduction and internal fixation of capitellar fractures with headless screws.
The outcome of operatively treated capitellar fractures has not been reported frequently. The purpose of the present study was to evaluate the clinical, radiographic, and functional outcomes following open reduction and internal fixation of capitellar fractures that were treated with a uniform surgical approach in order to further define the impact on the outcome of fracture type and concomitant lateral column osseous and/or ligamentous injuries. ⋯ Despite the presence of greater flexion contractures at the time of follow-up in elbows with Type-IV fractures or fractures with an ipsilateral radial head fracture, good to excellent outcomes with functional ulnohumeral motion can be achieved following internal fixation of these complex fractures. Type-IV injuries may be more common than previously thought; such fractures often are associated with metaphyseal comminution or a radial head fracture and may require supplemental fixation.

Risk factors in redisplacement of distal radial fractures in children.
The causes of redisplacement following closed treatment of distal metaphyseal radial fractures in children are still controversial. Various risk factors and radiographic indices have been suggested to predict redisplacement. The aims of this study were to prospectively identify the causes of redisplacement and to test the accuracy of previously described radiographic indices and our new method, the "three-point index." ⋯ Initial complete displacement and the degree of obliquity of the fracture line are the dominant factors affecting redisplacement. Our new radiographic index, the three-point index, should be used to predict redisplacement and assess the quality of the cast treatment of these fractures.
