Currently, monitoring protocols after tendon injury are based on ultrasonography evaluations of tendon. Unfortunately, these do not provide the clinician with any idea of how well the tendon is healing, it just tells them how well any gaps are filling in. Currently in human medicine, the technology exists to evaluate how hard or soft tissue is based on ultrasound. We aim to evaluate two of thes...

BACKGROUND Lesions in peripheral nerves are highly prevalent in the upper extremity. The present study compares different tendon transfer surgeries in patients with radial nerve palsy. METHODS Fifty patients with radial nerve palsy were randomly selected among patients who referred to Tehran 15th Khordad Hospital during 2006-2011. They were divided into two groups of 17 and 33 subjects. Sing...

Background: Tendon grafting is mostly required to repair an injury to flexor tendon and due to the importance of this tendon; it needs methods to speed up the re-vitality of the tendon allograft. OBJECTIVES: The aim was to investigate the efficacy of the mesenchymal cells and platelet rich plasma on the hydroxyproline content of frozen allograft tendons after grafting in lamb. METHODS: In this ...

Chitosan bears numerous properties, such as biocompatibility, biodegradability and non-toxicity making it suitable for use in different biomedical fields. Zinc (Zn) is required for fibroblasts proliferation and collagen synthesis as essential elements of wound healing. Its nanoparticles are well known for their capability to enhance wound healing by cell adhesion and migration improvement throu...

Three-dimensional integrated organ printing (IOP) technology seeks to fabricate tissue constructs that can mimic the structural and functional properties of native tissues. This technology is particularly useful for complex tissues such as those in the musculoskeletal system, which possess regional differences in cell types and mechanical properties. Here, we present the use of our IOP system f...

background tendon injuries are common and it takes a long time for an injured tendon to heal. adverse phenomena such as adhesion and rupture are associated with these injuries. finding a method to reduce the time required for healing whichimproves the final outcome, will lead to decreased frequency and intensity of adverse consequences. this study was designed to investigate the effects of basi...

tendon never restores the complete biological and mechanical properties after healing. bone marrow and recently adipose tissue have been used as the sources of mesenchymal stem cells, which have been proven to enhance tendon healing. stromal vascular fraction (svf), derived from adipose tissue by an enzymatic digestion, represents an alternative source of multipotent cells, which undergo differ...

background: despite the importance of hamstring tendon autograft, one major disadvantage in applying this technique in the surgical reconstruction of anterior cruciate ligament is individual variability in the tendon diameter. hence, the purpose of the present study was to use anthropometric parameters such as gender, height and body mass index to predict 4-strand (quadruple) hamstring tendons ...

Background: Palmaris longus (PL) is a muscle with marked variations. It is harvested as a tendon graft in many surgical proceduresin which a certain length of tendon is required. The aims of the present study were to determine the variations of this tendon in Iranian population and to find whether the length of PL tendon could be estimated by measuring the forearm length and height. Methods: We...
