Cobb Angle Measurement of Spine from X-Ray Images Using Convolutional Neural Network.

Scoliosis is a common spinal condition where the spine curves to the side and thus deforms the spine. Curvature estimation provides a powerful index to evaluate the deformation severity of scoliosis. In current clinical diagnosis, the standard curvature estimation method for assessing the curvature quantitatively is done by measuring the Cobb angle, which is the angle between two lines, drawn perpendicular to the upper endplate of the uppermost vertebra involved and the lower endplate of the lowest vertebra involved.

The modified finger-trap suture technique: a biomechanical comparison of a novel suture technique for graft fixation.

Purpose: The purpose of this study was to compare the tendon graft holding power of the newly devised modified finger-trap (MFT) suture technique with other currently used sutures.

Methods: We used 40 fresh-frozen porcine flexor profundus tendons randomly divided into 4 groups of 10 specimens. The experimental procedure was designed to assess percent elongation of the suture-tendon construct across four different tendon-grasping techniques: MFT suture, Krackow stitch, locking SpeedWhip stitch (Arthrex, Naples, FL), and nonlocking SpeedWhip stitch.

Treatment of unstable distal clavicle fractures with Knowles pin.

Background: Unstable distal clavicle fractures often need surgical treatment. This report describes a new intramedullary extra-articular Knowles pin fixation method to treat these unstable fractures.

Materials And Methods: Twelve patients with unstable distal clavicle fractures (Neer type II) had surgery with intramedullary extra-articular Knowles pin fixation.

Lower extremity kinematics and kinetics during level walking and stair climbing in subjects with triple arthrodesis or subtalar fusion.

The purpose of this study was to identify the kinematic and kinetic strategies used by patients with unilateral triple arthrodesis or subtalar fusion during level walking, stair ascent, stair descent and to determine the influence of these different conditions on kinematics and kinetics. Nine subjects with unilateral triple or subtalar fusion and five normal control subjects were recruited for this experiment. Temporal distance, kinematic and kinetic data were collected using a six camera 3-D motion analysis system and a custom fabricated set of stairs with five steps; the second and third steps were each instrumented with one force platform.
