Aesthetic plastic surgery.Aesthetic Plast Surg.2015 Apr;39(2):203-8. doi: 10.1007/s00266-015-0452-5. Epub 2015 Jan 29.
Brachial ptosis is one of the consequences of massive weight loss. At an early stage, brachial ptosis can be corrected by liposuction, dermolipectomy and liposuction, or minibrachioplasty while the most advanced stage requires extended brachioplasty. Since brachioplasty was first described, various

Journal of shoulder and elbow surgery / American Shoulder and Elbow Surgeons ... [et al.].J Shoulder Elbow Surg.2015 Mar 25. pii: S1058-2746(15)00069-5. doi: 10.1016/j.jse.2015.01.016. [Epub ahead of print]
BACKGROUND: The purpose of this study was to define the relationship between the humeral neck-shaft angle (NSA) and variations in the ideal entry portal aligned with the long axis of the intramedullary canal of the proximal humerus.METHODS: Three-dimensional images of 36 cadaveric humeri with variou
