Biomechanical analysis of pin placement for pediatric supracondylar humerus fractures: does starting point, pin size, and number matter?

Background: Several studies have examined the biomechanical stability of smooth wire fixation constructs used to stabilize pediatric supracondylar humerus fractures. An analysis of varying pin size, number, and lateral starting points has not been performed previously.

Methods: Twenty synthetic humeri were sectioned in the midolecranon fossa to simulate a supracondylar humerus fracture.

Gait analysis of children treated for moderate clubfoot with physical therapy versus the Ponseti cast technique.

Background: Nonoperative methods for clubfoot treatment include the Ponseti technique and French functional method. The purpose of this study was to compare the gait of children presenting with moderate clubfeet who were treated successfully with these techniques. We hypothesized: (1) no difference in gait parameters of moderate clubfeet treated with either of these nonsurgical techniques and (2) gait parameters after treatment for less severe feet would more closely approximate normal gait.
