Process parameters and post-processing heat treatment techniques have been developed to produce both shape memory and superelastic NiTi using Additive Manufacturing. By introducing engineered porosity, the stiffness of NiTi can be tuned to the level closely matching cortical bone. Using additively manufactured porous superelastic NiTi, we have proposed the use of patient-specific, stiffness-matched fixation hardware, for mandible skeletal reconstructive surgery. Currently, Ti-6Al-4V is the most commonly used material for skeletal fixation devices. Although this material offers more than sufficient strength for immobilization during the bone healing process, the high stiffness of Ti-6Al-4V implants can cause stress shielding. In this paper, …

Abstract
Anterolateral thigh flap is used for reconstruction of various soft tissue defects. We planned the study to evaluate the versatility of the anterolateral thigh flap as it may be used for reconstruction of head and neck, torso and extremities with minimal donor-site morbidity. The retrospective study was conducted at Aga Khan University Hospital, Karachi, and comprised date from October 2012 to December 2015. Of the 75 patients in which anterolateral thigh flap was used for reconstruction, 6(8%) flaps did not survive. The overall flap survival was 69(92%). Anterolateral thigh flap was versatile enough to provide soft tissue coverage to …
