Soft tissue injuries with associated bone defects are difficult to manage and often require prolonged treatment with repeated interventions. Frequently, a free flap is applied as a first step and bone grafting is carried out in a second procedure. Ideally, these two procedures are combined in one operation, utilizing a soft tissue flap with an attached vascularized bone fragment. The lateral arm flap can provide such an osteoseptocutaneous flap and has been utilized clinically with success; however, the vascular anatomy of the flap, especially the humeral fragment, has not been described in detail previously, and there is broad disagreement concerning its innervation. In this study, the arteries and nerves of 24 fresh cadaver arms were dissected after injection of colored latex. The levels of origin of the periosteal arteries of the humerus were also documented. The lateral arm flap has a consistent arterial supply from three septocutaneous perforating branches that are arranged in a predictable pattern. The lateral supracondylar ridge of the humerus is vascularized by direct branches of the posterior branch of the radial collateral artery and by arteries that arise from muscular branches supplying adjacent muscles. The innervation of the lateral arm flap is by the inferior lateral cutaneous nerve of the arm. Knowledge of the consistent vascular anatomy of the lateral humerus and soft tissue of the donor site allows an osteoseptocutaneous flap to be raised safely with an appropriate technique. We recommend use of the lateral arm flap with a humeral fragment for the treatment of combined soft tissue and bone defects when a single step surgical solution is indicated. 相似文献

The synthesis and properties of the bridged piperidine (oxaazabicyclo) compounds 8, 9, and 11 are described. A conformational analysis of these structures is compared with the representative GPR119 ligand 1. These results and the differences in agonist pharmacology are used to formulate a conformation-based hypothesis to understand activation of the GPR119 receptor. We also show for these structures that the agonist pharmacology in rat masks the important differences in human pharmacology. 相似文献

OBJECTIVES: This study is based on the 2000 Demographic and Health Survey (DHS) conducted in Haiti. Using the DHS information on women aged 15 to 49 who had given birth during the three years preceding the survey interview, this study was intended to: (1) examine the determinants of the likelihood of the women using prenatal care in the rural areas and in the urban areas of the country and (2) for the women who made at least one prenatal care visit, examine the determinants of the number of prenatal visits in the rural areas and the urban areas. METHODS: The multivariate analysis used logistic models to identify which factors explained the decision to seek prenatal care, and negative binomial models were used to determine how many prenatal visits were conducted by the subgroup of women who did make prenatal care visits. RESULTS: Estimated at the mean values of the control variables, the expected probability of using prenatal care services in rural Haiti was 77.16%, compared to 85.83% in urban Haiti. Among users of prenatal care services, mothers in rural areas made an expected number of 3.78 prenatal care visits, compared to 5.06 visits for the women in urban areas. CONCLUSIONS: A substantial percentage of pregnant women have access to prenatal care services in Haiti, but mothers in rural areas who decided to seek care still fell slightly below the four visits recommended by the World Health Organization. The education levels of both mothers and their partners is a dominant predictor of prenatal care use. Longer travel times and greater distances to health centers in rural areas constituted barriers to repeated visits. Policymakers and health care providers need to take these findings into consideration as they decide on the delivery and management of health care services in Haiti. 相似文献
