Randomized Controlled Trial Multicenter Study Comparative StudyNonoperative treatment compared with plate fixation of displaced midshaft clavicular fractures. Surgical technique.
Recent studies have shown a high prevalence of symptomatic malunion and nonunion after nonoperative treatment of displaced midshaft clavicular fractures. We sought to compare patient-oriented outcome and complication rates following nonoperative treatment and those after plate fixation of displaced midshaft clavicular fractures. ⋯ Operative fixation of a displaced fracture of the clavicular shaft results in improved functional outcome and a lower rate of malunion and nonunion compared with nonoperative treatment at one year of follow-up. Hardware removal remains the most common reason for repeat intervention in the operative group. This study supports primary plate fixation of completely displaced midshaft clavicular fractures in active adult patients.

Comparative StudyLateral entry compared with medial and lateral entry pin fixation for completely displaced supracondylar humeral fractures in children. Surgical technique.
Closed reduction and percutaneous pin fixation is the treatment of choice for completely displaced (type-III) extension supracondylar fractures of the humerus in children, although controversy persists regarding the optimal pin-fixation technique. The purpose of this study was to compare the efficacy of lateral entry pin fixation with that of medial and lateral entry pin fixation for the operative treatment of completely displaced extension supracondylar fractures of the humerus in children. ⋯ With use of the specific techniques employed in this study, both lateral entry pin fixation and medial and lateral entry pin fixation are effective in the treatment of completely displaced (type-III) extension supracondylar fractures of the humerus in children.

Randomized Controlled TrialAcute patellar dislocation in children and adolescents: a randomized clinical trial.
The treatment of acute patellar dislocation in children is controversial. Some investigators have advocated early repair of the medial structures, whereas others have treated this injury nonoperatively. The present report describes the long-term subjective and functional results of a randomized controlled trial of nonoperative and operative treatment of primary acute patellar dislocation in children less than sixteen years of age. ⋯ The long-term subjective and functional results after acute patellar dislocation are satisfactory in most patients. Initial operative repair of the medial structures combined with lateral release did not improve the long-term outcome, despite the very high rate of recurrent instability. A positive family history is a risk factor for recurrence and for contralateral patellofemoral instability. Routine repair of the torn medial stabilizing soft tissues is not advocated for the treatment of acute patellar dislocation in children and adolescents.

Publication bias in orthopaedic research: an analysis of scientific factors associated with publication in the Journal of Bone and Joint Surgery (American Volume).
Positive outcomes are common in the orthopaedic literature, and there are many who believe it may be due to the preferential publication of studies with positive findings-a phenomenon known as publication bias. The purpose of this investigation was to determine whether positive findings rendered a manuscript submitted to The Journal of Bone and Joint Surgery (American Volume) more likely to be accepted for publication. ⋯ We found no evidence of publication bias in the review of manuscripts for publication by The Journal of Bone and Joint Surgery, as positive and nonpositive studies were accepted at similar rates. The dearth of nonpositive studies in the orthopaedic literature is of concern, and may be due largely to investigator-based factors. Orthopaedic researchers should submit negative and neutral studies for publication, confident that the likelihood of acceptance will not be influenced by the direction of study findings.

Angle-stable and compressed angle-stable locking for tibiotalocalcaneal arthrodesis with retrograde intramedullary nails. Biomechanical evaluation.
Retrograde intramedullary nailing is an established procedure for tibiotalocalcaneal arthrodesis. The goal of this study was to evaluate the effects of angle-stable locking or compressed angle-stable locking on the initial stability of the nails and on the behavior of the constructs under cyclic loading conditions. ⋯ Regardless of the bone model, the nails with angle-stable or compressed angle-stable locking had better initial stability and better stability following cycling than did the nails with static locking.
