bone-patellar tendon auto graft is probably the most widely used graft for acl reconstruction. several methods for graft fixation have been described. to avoid intra-articular hardware we adopt biological fixation with a femoral trapezoidal press-fit fixation. a prospective study was performed on 30 consecutive active people who underwent acl reconstruction with this technique by two surgeons b...

background and aims. localized gingival recession presents as a special therapeutic problem. subjective parameters and donor site morbidity are often overlooked while deciding on any treatment option. materials and methods. 22 subjects were equally divided in group a (lateral pedicle graft) and group b (free mucosal graft). subjective evaluation of post operative sensitivity, discomfort and ble...

arteriovenous fistula is considered as a prerequisite in patients with chronic renal failure undergoing hemodialysis. the purpose of this study was to compare the effectiveness and side effects if any of native vein and synthetic grafts in these patients. from april 2002 till july 2003, a total of 37 patients were referred to us for the utilization of these grafts. in 16 out of these patients w...

arteriovenous fistulae traditionally have been placed in the upper extremity. experience with groin hemodialysis access has been discouraging because of high infection rates and associated limb amputation. the aim of this study was to determine infection rates, patency rates, and possible predictive factors for prosthetic thigh angioaccess outcomes in our hemodialysis patient population. a pros...

abstract background and aims. the aim of this study was to evalute the effect of double pedicle graft (dpg) with and without plasma rich in growth factor (prgf) in the treatment of miller's cl i and ii gingival recessions. materials and methods. thirty two bilateral buccal gingival miller’s cl i and ii recessions were selected. sixteen of the recessions were treated with dpg and prgf (test grou...

BACKGROUND: Dental disease, trauma and maxillofacial surgeries can cause alveolar bone defects. Among different kinds of treatment, autogenous bone grafts is accepted as a golden standard. On the other hand, because of limitation of treatment with autogenous bone grafts, osteogenic cells derived from stem cells are suggested. OBJECTIVES: The aim of this study was to compare the mean density of ...

BACKGROUND Full-thickness skin graft (FTSG) is a very versatile tool regularly used in small sizes. With the established knowledge of the graft take through the margins as well as wound bed, we extended the use of the FTSG for reconstruction of large-sized defects with satisfactory results.  METHODS We presented our experience in wound reconstruction using FTSG in 28 patients. We select...

Cellulose was modified by polystyrene (PS) and polyacrylonitrile (PAN) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. For this purpose, first, the graft polymerization of styrene (St) onto cellulose fibers was performed by using suspension polymerization and ...

objective: to assess the effect of combination of pulsed electromagnetic fields (pemf) with predatory stress on transected sciatic nerve regeneration in rats.  methods: in sham- operated group (sog) the nerve was manipulated and left intact. the 10-mm rat sciatic nerve gap was created in rats. in transected group (transected) nerve stumps were sutured to adjacent muscle and in vein graft group ...
