The "split" gluteus musculocutaneous flap is a useful flap for perineal and ischial reconstruction. The flap uses the superficial 1 to 2 cm of the gluteus muscle, supplied by proximal parasacral perforators. It can be raised simply, quickly, and with minimal blood loss. Importantly, the deep muscle is left in place and remains innervated and well-vascularized. Deep structures are protected, and other flap options are preserved. Anatomic findings based on 16 cadaver dissections (8 cadavers with bilateral dissections) are presented. Representative case reports and our experience with 18 consecutive cases in 17 patients are presented.

A new operative technique has been developed for augmentation mammaplasty. Through an inframammary incision, the anterior rectus sheath is entered, and the pocket is dissected in an entirely submuscular plane. We have performed this procedure in 112 patients to date. Complications have been few. The capsular contracture rate in 90 patients followed for greater than 1 year is 7 percent. The inframammary crease can be lowered using this technique, making mastopexy unnecessary in most patients with moderate ptosis.

A 60-year-old man with a severe degree of pectus excavatum and previous coronary artery surgery required aortic valve replacement. At operation the sternal wires were found to be densely adherent to the aortic wall. We describe the surgical technique, which was carried out uneventfully.

Fifty-two pig metacarpal bones were osteotomized and internally fixed using a variety of wiring techniques. Fixed constructs were then loaded to failure while several biomechanical parameters were measured. Tension-band stabilization provided superior strength, stiffness, and approximation. Crossed K-wire fixation was distinctly inferior with regard to these same parameters.
