OBJECTIVE Osteoarthritis (OA) is a multi-factorial disease and genetic factor is one of the important etiologic risk factors. Various genetic polymorphisms have been elucidated that they might be associated with OA. Recently, several studies have shown an association between Growth Differentiation Factor 5(GDF5) polymorphism and knee OA. However, the role(More)
Atrophic non-union is attributed to biological failure of the fracture repair process. It occurs in up to 10% of fractures, results in significant morbidity to patients, and treatment often requires complex reconstructive procedures. We tested the ability of human bone derived marrow mesenchymal stem cells (MSC), and human adipose derived pericytes (the(More)
Mesenchymal stem/stromal cells (MSCs) can regenerate tissues by direct differentiation or indirectly by stimulating angiogenesis, limiting inflammation, and recruiting tissue-specific progenitor cells. MSCs emerge and multiply in long-term cultures of total cells from the bone marrow or multiple other organs. Such a derivation in vitro is simple and(More)
OBJECTIVE To demonstrate the new sensory restoration technique in radial nerve injury using the first branch of dorsal ulnar cutaneous nerve as the donor sensory nerve. MATERIAL AND METHOD Forty formalin-preserved cadavers (18 males and 22 females) were used as the subjects of the present study. The localization of the origin of first branch of dorsal(More)
BACKGROUND Estrogen receptor-alpha single-nucleotide polymorphism (ER-alpha SNP) has previously shown its susceptibility to knee osteoarthritis (OA) but this association cannot be applied to ethnic groups with different genetic backgrounds. OBJECTIVE To characterize the genetic association between ER-alpha SNP and knee OA in the Thai. MATERIAL AND(More)
INTRODUCTION It has been reported that cells or growth factors might improve bone regeneration in nonunion. However, the intrinsic potential of the nonunion tissue to regenerate bone is still unclear; in particular, it is not known whether there are progenitor cells within the nonunion. Thus, in this study, a clinically relevant model has been developed to(More)
OBJECTIVE Mesenchymal stem cells (MSCs) have potential in orthopaedic applications as they are able to differentiate into bone and cartilage. These cells can be isolated from a variety of adult tissues. Three sources that are relevant for orthopaedic applications are bone marrow, periosteum and adipose tissue. The purpose of the present study was to compare(More)
A total of 100 cadaveric limbs were dissected to study the anatomy of the forearm and hand extensor musculature. Four types of contributions to the index finger were found for the extensor indicis proprius (EIP), including one new type where the double tendons of the EIP inserts volar and radial to the extensor digitorum communis of the index finger(More)
OBJECTIVES The radiographic union score for tibial (RUST) fractures was developed by Whelan et al to assess the healing of tibial fractures following intramedullary nailing. In the current study, the repeatability and reliability of the RUST score was evaluated in an independent centre (a) using the original description, (b) after further interpretation of(More)
OBJECTIVE To study pain relief curve correction, and functional outcomes after decompression and instrumented arthrodesis in degenerative lumbar scoliosis patients with spinal stenosis. MATERIAL AND METHOD Thirty-one degenerative scoliosis patients with symptom of spinal stenosis who underwent decompression and fusion with pedicular screw plate(More)
