Autograft is gold standard treatment for peripheral nerve repair up to now. Eggshell membrane (ESM) as nerve guide channel effectively enhances nerve regeneration. Dimethyl sulphoxide (DMSO) has anti-inflammatory and anti-oxidant properties. The aim of this study was to evaluate the effect of DMSO+eggshell membrane guide channel on sciatic nerve regeneration in rats. Thirty two adult male rats ...

The radiographic and clinical results of 105 patients with symptomatic spinal deformities were categorized retrospectively based on surgical approach and type of bone autograft or allograft used for each patient's fusion surgery into seven different groups and compared with one another. The three bone autograft control groups were posterior autograft only (n = 20), anterior autograft only (n = ...

Background/aim: This study was performed to show the efficacy of in situ local autograft with a comparison of in situ local autograft, local autograft with allograft, and local autograft with posterior iliac crest autograft.Materials and methods: In this prospective randomized study, a total of 65 adolescent idiopathic scoliosis (AIS) patients were separated into 3 groups: Group 1 using local a...

Objective- Bone regeneration is a multifactorial phenomenon which contributed to several factors. It is reported that risedronate is effective for musculoskeletal diseases. The current study was to determine effectiveness of the risedronate-loaded nano capsules for calvaria healing in rabbit.Design- Experimental study.Procedures- 15 white adult male New Zealand rabbits were used. Fo...

Background: The limited availability of donor sites for nerve grafting has continued to stimulate research toward finding suitable alternatives for autograft. The aim of this research was to study the effect of piezoelectric channel and collagen gel on nerve regeneration. Materials and methods: This research is an experimental study. Forty eight male rats (200-250 gr) were used. After axotomy...

OBJECTIVES The Ross procedure is the aortic valve-replacement procedure of choice in children. Nonetheless, late autograft re-operation for dilatation and/or valve regurgitation is of concern. We examined whether preoperative haemodynamic manifestation (e.g., stenosis, regurgitation and mixed aortic valve disease) affected late re-operation risk. METHODS Medical records of 227 children who un...

BACKGROUND Ankle and hindfoot arthrodesis is often supplemented with autograft to promote bony union. Autograft harvest can lead to increased perioperative morbidity. Purified recombinant human platelet-derived growth factor BB homodimer (rhPDGF-BB) has stimulated bone formation in mandibular defects and hindfoot fusion. This randomized controlled trial evaluated the efficacy and safety of rhPD...

closure of fascia after transverse rectus abdominis musculocutaneous (tram) flap has usually been performed with direct closure or synthetic material. the dermal autograft was removed from zone iv of flap was an alternative to reinforce fascial closure. the dermal autograft was used in 34 patients after tram harvest for breast, head and neck reconstruction and prolene mesh was used in 42 other ...

With patients undergoing first time 1st metatarsophalangeal joint arthrodesis using graft material when it was required to fill cystic bone voids, we retrospectively compared the time to fusion (clinical and radiographic), and non-union rate between the patient’s own bone autograft (n = 62) versus a mesenchymal stem cell impregnated allograft group (n = 51). A third control group (n = 52) was i...

BACKGROUND AND PURPOSE Bone morphogenic proteins (BMPs) can be used in non-unions to replace autograft. BMPs induce osteoblasts and (less well known) also osteoclasts, which can in turn be controlled by a bisphosphonate. In the present study, our aim was to improve the biological effect of autologous bone graft by adding an anabolic BMP, with or without bisphosphonates, in an open-fracture mode...
