چکیده
109 Bone grafting is an important aspect of foot and ankle surgery.1 Despite the long history and widespread use of bone grafts and substitutes,2 there have been few studies documenting patterns of utilization of bone grafting by podiatric surgeons. A survey on the use of bone grafts among orthopedists was reported in 1984 by Miller et al.3 The present study was undertaken in order to determine patterns of utilization of bone grafts in foot and ankle surgery. In particular, this study was designed to demonstrate how indications for allogeneic bone and autogenous bone have changed and to examine the effectiveness of bone grafts for specific foot and ankle conditions. Bone grafting can be used for many surgical procedures. Facilitation of fusion, repair of nonunions (Fig. 1),4 and packing of cysts are all common reasons for bone-graft surgery. Reconstructive surgical procedures often require bone grafts (Fig. 2).5 Lengthening procedures for repair of brachymetatarsia (Fig. 3)6 and opening wedge procedures such as cuneiform osteotomies are other examples of procedures using bone grafts (Fig. 4).7 Surgeons can choose from many different materials, although only a few are commonly used. An increasing number of choices are available to surgeons, including various forms of autogenous bone,8 allogeneic bone,9 and bone substitutes.10 These choices obligate the surgeon to be familiar with the biology and biomechanics of these materials. Bone grafts are classified by standard transplantation terminology.11 Autogenous bone is procured Bone Grafting in Foot and Ankle Surgery A Review of 300 Cases

متن کاملN ov 2 00 6 A Combination Theorem for Strong Relative Hyperbolicity Mahan
We prove a combination theorem for trees of (strongly) relatively hyperbolic spaces and finite graphs of (strongly) relatively hyperbolic groups. This gives a geometric extension of Bestvina and Feighn's Combination Theorem for hyperbolic groups.
متن کاملThermal transport in the Falicov-Kimball model
We prove the Jonson-Mahan theorem for the thermopower of the Falicov-Kimball model by solving explicitly for correlation functions in the large dimensional limit. We prove a similar result for the thermal conductivity. We separate the results for thermal transport into the pieces of the heat current that arise from the kinetic energy and those that arise from the potential energy. Our method of...
