Our findings complement the theory from in vitro studies suggesting that neck impingement on the elevated titanium rim is the probable cause of the increased frequency of squeaking with this design.
Primary repair or reconstruction of EHL tendon lacerations is a reliable procedure that restores hallux alignment and function in most patients as measured by the validated FAAM questionnaire. Deep tendon transfer from the extensor digitorum longus may be performed if EHL tendon edges are not opposable thus eliminating the need for allograft reconstruction.
The authors prospectively studied three-dimensional kinematics and kinetics of gait in children recovering from a closed, isolated, nonpathologic fracture of the femoral diaphysis, who had been randomly assigned to management by monolateral external fixation or early hip spica casting. The aims were to investigate the gait patterns soon after injury and at 2 years after injury. Children treated with external fixation, walking with the external fixator in situ, demonstrated asymmetric gait abnormalities in all three anatomic planes affecting the trunk, pelvis, hip, knee, and ankle. This appears to be a strategy to minimize movement and pain at the fixator pin sites. The gait pattern normalized rapidly after removal of the external fixator with few kinematic or kinetic abnormalities and no clinically significant disturbances of gait at 2 years after injury. In contrast, children in the early hip spica cast group developed a "crouch gait" pattern in the sagittal plane, most likely due to weakness. They also had abnormal coronal plane kinematics related to shortening of the injured side. Gait patterns improved, but at 2 years there were some persistent gait deviations, probably related to residual limb length discrepancy.
A posterior approach to the elbow utilizing an olecranon osteotomy has been shown to provide excellent visualization of the distal humerus articular surface. However, many bony stabilization and fixation methods for the olecranon osteotomy are usually prominent, frequently symptomatic, and often require a second operation for removal. This paper evaluates the use of an innovative device, the olecranon sled, in fixation of olecranon osteotomies for exposure of intra-articular distal humerus fractures and provides follow-up results. A retrospective review of all patients with intra-articular distal humerus fracture treated through an olecranon osteotomy approach and fixed with an olecranon sled, between September 2008 and December 2011 was conducted. Charts and radiographs were reviewed to determine olecranon union or nonunion, presence of symptomatic hardware, and need for secondary surgery to remove symptomatic olecranon fixation. Fourteen patients were included in the study. Average clinical follow-up was 33.5 weeks (range, 6 to 118 wk). There were no olecranon nonunions. One patient underwent additional surgery for symptomatic hardware removal (7.1%). Two additional procedures were performed; 1 for revision open reduction and internal fixation of distal humerus fracture nonunion (7.1%) and 1 for release of elbow contracture (7.1%). Although follow-up is limited, the use of this device has been associated with excellent rates of olecranon union with a low rate of symptomatic hardware requiring removal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
