We screened the small molecule compounds that stimulate osteogenesis by themselves or promote bone morphogenetic protein (BMP)-induced formation. found a specific inhibitor for MAPK/extracellular signal-regulated kinase (MEK)-1, promoted early osteoblastic differentiation and mineralization of extracellular matrix (ECM) in C2Cl2 pluripotent mesenchymal cells treated with recombinant human BMP-2 (rhBMP-2) MC3T3-E1 preosteoblastic cells. ALP activity was synergistically increased treatment...
Background: Osteoporotic fragility fractures frequently occur at the distal part of radius. This suggests that initial osteoporosis evaluation this site may inform screening and treatment to prevent additional fractures. The purpose study was investigate utility forearm dual x-ray absorptiometry (DXA) as a tool assess risk Methods: retrospective, case-control included postmenopausal women who had sustained radial fracture (fracture group, n = 110) with no history (control 95). DXA...
We examined the outcomes and levels of patient satisfaction in 202 consecutive cases ultrasound-guided supraclavicular brachial plexus block (SBPB) upper limb surgery performed between September 2007 March 2010. All blocks were by orthopaedic surgeons using ultrasound visualisation with a high-frequency linear probe. The probe was placed coronal–oblique plane fossa, puncture ‘in-plane’ from lateral to medial. Most 0.75% ropivacaine/1% lidocaine (1:1), or without adrenaline 1:200 000...
Aims Low-energy distal radius fractures (DRFs) are the most common upper arm correlated with bone fragility. Vitamin D deficiency is an important risk factor associated DRFs. However, relationship between DRF severity and vitamin not elucidated. Therefore, this study aimed to identify correlation serum 25-hydroxyvitamin-D level, which indicator of deficiency. Methods This multicentre retrospective observational enrolled 122 female patients aged over 45 years DRFs extension deformity. was...
Understanding the complex fragmentation of intra-articular distal radial fractures contributes to achieving anatomical reduction during surgery. This study aimed clarify three-dimensional displacement patterns in dorsally angulated, fractures. We identified five characteristic fragments: a key fragment, dorsal ulnar corner, wall, column and anterior column. The fragment was displaced with deviation, pronation extension dorsal, proximal translations. corner resulted gap, step-off deepened...
Abstract This study describes the distributions of bone morphogenetic protein (BMP)‐2 as well mRNAs for BMP receptor type IB (BMPRIB), collagen types II (Col II) and III III) in a growing “cartilage cap” osteochondroma. In situ hybridization immunohistochemical were performed using histological sections obtained during surgery. BMP‐2 was detected mesenchymal cells outer fibrous layer chondrocytes inner cartilaginous matrix, positive Col II, respectively. BMPRIB mRNA distributed chondrocytes....
Kirner's deformity is a rare skeletal first described in Germany 1927. It characterized by progressive palmar-radial curvature of the distal phalanx small finger. Here, we present case 15-year-old boy with both little fingers, who was treated percutaneous corrective osteotomy. This followed successful outcome after 36 months.
In patients with rheumatoid arthritis (RA), juxta-articular intraosseous cystic lesions may cause spontaneous pathological fractures. The outcome of curettage and the packing such interconnected porous calcium hydroxyapatite ceramic (IP-CHA) was investigated. Twelve were treated in ten RA (three men seven women a mean age 59 years). Ten associated impending fracture involving articular surface. all patients, bone cavity IP-CHA done. Assessment based on final radiographs obtained an average...

A 46-year-old woman sustained a rupture of the extensor pollicis longus tendon more than 30 years after wrist injury. She was successfully treated with palmaris graft and excision osseous spur. Attrition by newly formed spur major mechanism.
Acute posterolateral rotator elbow dislocation in a child is rare and can be easily misdiagnosed due to immaturity of the epiphysis. This first case occult combination with an olecranon fracture. We report our experience this case, which was not diagnosed correctly by plain radiographs.An 11-year-old Asian boy suffered severe pain swelling his right after outstretched arm hit car dashboard motor vehicle accident. Plain radiographs showed only minimally displaced fracture tiny lateral...
<title>Abstract</title> Background: Nodular fasciitis is a benign, usually self-limiting myofibroblastic proliferation with predilection for the upper extremities, trunk, and head neck of young adults. Although it arises within subcutaneous tissues, may also occur skeletal muscle, dermis, vessels, peripheral nerves. Since nodular not widely recognized to arise joints, therefore cause diagnostic confusion in this uncommon setting. Histology can vary considerably can, therefore, mimic other...
Nodular fasciitis is a benign, usually self-limiting myofibroblastic proliferation with predilection for the upper extremities, trunk, and head neck, almost all of which harbor USP6::MYH9 fusion. Since nodular not widely recognized to arise within joints, it may therefore cause diagnostic confusion in this uncommon setting. We report an unusual tumor 11-year-old patient who presented 6-month history right elbow swelling pain. Histology revealed that was composed solely proliferating bland...
Abstract Purpose Ultrasound‐guided supraclavicular brachial plexus block (SCBPB) is performed by surgeons for upper limb anesthesia; however, certain patients need additional local anesthesia. This study aimed to identify risk factors anesthetic injection requirements. Methods In total, 269 receiving ultrasound‐guided SCBPB were enrolled. Patient age, sex, body mass index, drug dose, surgeon expertise (hand or resident), tourniquet time, comorbidities (diabetes mellitus and mental...
