While incorrect length of a fibular fracture reduction can be measured by plain radiographs, accurate imaging of rotational deformities requires computed tomography (CT). Operative correction of fibular malrotation has not been accurately measured. The aim of this study was to evaluate the accuracy of operative correction of fibular malrotation. ⋯ Considering the error margin for CT analysis, correction within 5 to 10 degrees seems practical.

Comparative Study
Comparison of augmentation methods for internal fixation of osteoporotic ankle fractures.
Internal fixation of osteoporotic ankle fractures is associated with failure of fixation. This study compared different augmentation methods biomechanically. ⋯ Strategies to augment internal fixation of osteoporotic ankle fractures may minimize risk for failure of fixation and may enable early weight bearing mobilization and return to function in elderly patients.

The aim of the current study was to compare the compression forces achieved by the new commercial mini compression screws in cortical and cancellous bone. ⋯ Headed screws may be preferable to headless differential pitch screws in situations where compression is important ie, arthrodeses or fracture fixation. Care should be taken not to countersink the headless screws during insertion into cortical bone.

The influence of the knee angle on plantarflexion moments after Achilles tendon repair has yet to be analyzed. It was hypothesized that flexion of the knee joint will disproportionately influence isometric plantarflexion moments after Achilles tendon repair. ⋯ The flexion angle of the knee had no influence on plantarflexion moments when comparing the involved with the noninvolved leg after open or percutaneous Achilles tendon repair. Weakness of plantarflexion after open or percutaneous Achilles tendon repair is determined by the position of the ankle joint rather than by the flexion angle of the knee.
