Novel intramedullary device for lengthening transfemoral residual limbs.

Background: Lower limb loss is a highly disabling medical condition that can severely impact a person's quality of life. Recovery becomes especially challenging if an amputee has a short residual limb, which can complicate proper prosthetic fitting, causing discomfort, difficulties in suspension, and reduced mobility. Current limb lengthening techniques such as the Ilizarov apparatus and external fixators are cumbersome, uncomfortable, and have high complication rates.

Hand surface landmarks and measurements in the treatment of trigger thumb.

Purpose: To determine hand surface landmarks and measurements that may be useful in localizing the A1 pulley and digital neurovascular structures in the treatment of trigger thumb.

Methods: We highlighted 4 surface landmarks in 20 adult cadaveric hands: the radial border of the index finger, the ulnar border of the thumb, the thumb interphalangeal joint flexion creases, and the thumb metacarpophalangeal joint creases. We injected the radial arteries with red latex and dissected the thumbs.
