The purpose of this study was twofold: (a) to introduce a new three-dimensional digital assessment technique for the estimation of angular and rotational malunion and (b) to determine if an association exists between tibial malunion and functionally defined post-traumatic degeneration at the knee and ankle joint. ⋯ This study suggests that failure to meet conventionally accepted standards for tibial alignment might be common. Fortunately, these values were not associated with adverse functional outcomes. A three-dimensional system, which determines the functional mechanical axis of the knee and tibiotalar joints, may be a valuable and reliable method by which to determine malunion after fracture fixation.

To investigate the use of the Ilizarov circular fixator and nail retention in treating diaphyseal nonunion following previous intramedullary nailing. ⋯ There is a role for the use of the Ilizarov fixator with nail retention in resistant long bone diaphyseal nonunion in carefully selected patients. This method can achieve high union rates where other treatment methods have failed.

Comparative Study
Assessment of articular fragment displacement in acetabular fractures: a comparison of computerized tomography and plain radiographs.
Quantitatively evaluate plain radiographs, relative to computed tomography (CT) scans, for assessment of articular fragment displacement (step and gap) in displaced acetabular fractures and in canine osteotomized acetabular specimens. ⋯ 1) Plain radiographs showed poor sensitivity for the detection of step and gap deformities in patients with acetabular fractures and in osteotomized canine specimens, relative to CT scans; 2) differences between CT and plain radiographs in both specimen types were greatest with the most clinically relevant deformity-i.e., step; and 3) CT scans are essential and should continue to be used in conjunction with plain radiographs in the preoperative evaluation of displaced acetabular fractures and perhaps should be considered in the postoperative assessment of fracture reduction.

The objectives of this study are to describe the anatomic findings relative to anterior pelvic endoscopy, determine the potential use of endoscopy for reduction and fixation of fractures of the anterior pelvic ring, and report two illustrative cases performed using this method. Using the windows described, endoscopy permits placement of plates and screws on top of the symphysis pubis, reduction of internally displaced fragments, and performance of percutaneous procedures that do not harm anatomic structures.

Assess the characteristics associated with the risk of complications and mortality in children sustaining pelvic fractures. ⋯ Children with pediatric pelvic fractures require careful evaluation for other body-area injuries, as these are most likely to be related to hemorrhage or mortality.
