Case Reports
Repair of a floating sternum with autologous rib grafts and polylactide bioabsorbable struts in an 18-year-old male.
Failed regeneration of costal cartilage after open repair of pectus chest wall deformities can result in a floating sternum. A floating sternum can be repaired by insertion of a rib graft between the rib and sternum, and stabilization with a metal strut. The metal implant is usually removed with a second operation. ⋯ He had an uncomplicated peri-operative course. One year later, the sternum had a normal appearance and was sturdy. A second operation for removal of hardware was not necessary.

Case Reports
A case of 46, XY DSD presenting as a crossed ectopic gonad with a contralateral sliding inguinal hernia.
A three-month-old boy was referred to our facility for the treatment of a right impalpable testis, left inguinal hernia, and penoscrotal hypospadias with asymmetric external genitalia. The left gonad was palpated in the left scrotum. The chromosomal study revealed a normal male 46, XY karyotype. ⋯ A one-stage hypospadias repair using Koyanagi procedure was also performed. The pathological findings showed an ovarian stroma in the right gonad and left ovary. Only Sertoli cells were detected in the biopsied specimen from the left testis.
