Hydroxyapatite (HA) has been widely used as a bone graft substitute. In this study, we investigated whether the addition of osteogenic protein-1 (OP-1) further enhanced the weak osteoinductive properties of hydroxyapatite when loaded with human mesenchymal stem cells (h-MSCs). Over a 14 day period, cell proliferation in both groups was assessed(More)
BACKGROUND Allografting is currently used in lower limb reconstruction surgery. Demineralised bone matrix (DBM) is more osteoinductive compared with allografts but lacks mechanical strength. Osteogenic protein-1 (OP-1) can improve the osteoinductivity of the allograft, however recent reports indicate significant allograft resorption when it is combined with(More)
Impaction allografting is a bone tissue engineering technique currently used in lower limb reconstruction orthopedic surgery. Our hypothesis was that biological optimization can be achieved by demineralization and addition of osteogenic protein-1 (OP-1) to the allograft. The objective of our in vitro study was to evaluate human mesenchymal stem cell (MSC)(More)
BACKGROUND Estrogens and several other endogenous substances are recognised as being important in the process of wound healing. However, the effect of aromatase and aromatase inhibition in the wound healing process has yet to be fully defined. OBJECTIVE A review of the in vitro and in vivo evidence on the effect of aromatase inhibition on wound healing.(More)
OBJECTIVES To assess the influence of financial constraints on access to different components of spinal cord injury (SCI) management in various socio-economic strata of the Indian population. SETTING Indian Spinal Injuries Centre (ISIC). METHODS One hundred fifty SCI individuals who came for follow-up at ISIC between March 2009 and March 2013 with at(More)
Lumbar spinal stenosis in the presence of degenerative spondylolisthesis is generally treated by means of surgery. The role of lumbar decompression without fusion is not clear. Therefore, the aim of this study was to assess whether patients who undergo decompression alone have a favourable outcome without the need for a subsequent fusion. This is a(More)
