Bone grafting is an essential part of most total hip acetabular reconstructions. There are a limited number of surgical options, each with inherent disadvantages for the management of structural acetabular defects. In this cadaver study, the authors aimed to evaluate the availability of vascularized pedicled iliac crest graft for the purpose of acetabular reconstruction. ⋯ The average pedicle length was sufficient for coverage of the superior and anterior acetabular walls. The access to the posterior wall, however, required modification of the bone size. A vascularized pedicled iliac crest graft is suitable for the reconstruction of selected acetabular deficiencies.

Injury to the ilioinguinal and iliohypogastric nerves after a McBurney's incision have been reported to cause paralysis of the conjoint tendon that may lead to the development of an indirect inguinal hernia. This study reports on the incidence of ilioinguinal and iliohypogastric nerve sectioning after the performance of a classic McBurney's incision as well as the distance and relationship of the ilioinguinal and iliohypogastric nerves to the anterior superior iliac spine and a classic McBurney's incision. The right iliac fossa and lumbar region of 33 cadavers were dissected for the uncovering of the ilioinguinal and iliohypogastric nerves after a correct McBurney's incision was made. ⋯ The mean distance between the ilioinguinal nerve and the incision line was 41.89 mm and 34.63 mm between the iliohypogastric nerve and the incision line. The ilioinguinal and iliohypogastric nerves were found to be 6.69 mm and 12.08 mm from the anterior superior iliac spine, respectively. No ilioinguinal or iliohypogastric nerve was injured during all 33 McBurney's incisions.

Comparative Study
Study of the carrying angle of the human elbow joint in full extension: a morphometric analysis.
This study measured the carrying angle of the elbow joint in full extension in 600 students, using the supplementary angle to that between the longitudinal axis of the arm and that of the forearm. The mean carrying angle was 12.88 degrees +/-5.92: 10.97 degrees +/-4.27 in men and 15.07 degrees +/-4.95 in women. ⋯ We confirmed the inverse relationship between the carrying angle and the intertrochanteric diameter. Also, the type of constitution influences the value of the carrying angle, especially in women.
