Currently, volar locking plates are commonly used to treat distal radius fractures (DRF) because of their stable biomechanical construct and they cause less soft tissue disturbance allow early mobilisation the wrist. Complications such as rupture tendons have been reported occur with use plates. We describe six cases extensor pollicis longus (EPL) after EPL tendon injuries occurred in 2.1% (6/286) DRF surgery. The causes surgery were protrusion head tip insufficient reduction dorsal roof...
The use of bioabsorbable implants to negate the need for subsequent removal could offer major clinical advantages fixation fractures. aims this study were compare mechanical properties novel plates with those titanium in a fracture model and demonstrate results these new metacarpal fractures.The first set experiments compared plates. Two types (one-third tubular semi-tubular cross-section) made hydroxyapatite/poly-L-lactide two (for 1.5 2.0-mm screws) tested. Each plate was fixed on...
Acetaldehyde dehydrogenase 2 (ALDH2) is an enzyme involved in redox homeostasis as well the detoxification process alcohol metabolism. Nearly 8% of world’s population have inactivating mutation ALDH2 gene. However, expression patterns and specific functions skeletal muscles are still unclear. Herein, we report that expressed muscle localized to mitochondrial fraction. Oxidative had a higher amount protein than glycolytic muscles. We next comprehensively investigated whether knockout mice...
Calcium balance is important in bone homeostasis. The transient receptor potential vanilloid (TRPV) channel a nonselective cation permeable to calcium and activated by various physiological pharmacological stimuli. TRPV1 TRPV4, particular, have roles intracellular Ca2+ signaling extracellular homeostasis cells. TRPV4 separately mediate osteoclast osteoblast differentiation, deficiency any of these channels leads increased mass. However, it remains unknown whether mass increases the absence...
Abstract This study compared hand function and the cost-effectiveness of treatment between collagenase Clostridium histolyticum (CCH) injection limited fasciectomy for patients with Dupuytren’s contracture (DC). The CeCORD-J is a prospective, multicenter, non-randomized controlled, observational two parallel groups. Participants were DC multiple affected fingers, including flexion proximal interphalangeal (PIP) joint. primary outcome was Hand10 score, as patient-reported measure (PROM). We...
We report a case of Linburg-Comstock syndrome, which is characterized with anomalous tendon slips connecting flexor pollicis longus (FPL) to the digitorum profundus (FDP), usually at index finger. The present patient started be carpenter and was suffering from his disability flexing thumb finger independently when he handled screws in work. surgically removed tendinous connection FPL FDP tendon. After surgery, could work as without any difficulty. Surgical disconnection effective treatment....
Dorsal displaced distal radius fracture (Colles' fracture) is very common and could occur from fragility in middle-aged elderly people. Many Colles' fractures are still treated conservatively clinics without hospitalization. Internal fixation using a palmar locking plate has been the standard treatment, but some complications have reported. The aim of this study was to analyze changes radiographic parameters over time patients with fractures, establish whether type influenced these changes....
To assess the vitamin D status in postmenopausal women with osteoporotic fractures, determine its concentration by fracture site at clinical setting, and compare proportion of deficiency that reported literature.The prospective study included 317 fractures who were treated consecutively from 2016 to 2018. After obtaining informed consent for participation seamless treatment osteoporosis against study, which is our initiative prevent secondary we registered patients, examined bone mineral...
The efficacy of negative pressure wound therapy (NPWT) in the treatment skin defect wounds has been established, but it is difficult to apply hand surgery because easy occurrence air leaks. We report two cases performing NPWT with surgical gloves. Case1: A 37-year-old male was injured on his right dorsal from a punch. He presented our hospital three days after injury swelling and pain. infected contused, so lavage debridement (W&D) were performed under local anesthesia. condition didn't...
Aldehyde dehydrogenase 2 (ALDH2) catalyses aldehyde species, including alcohol metabolites, mainly in the liver. We recently observed that ALDH2 is also expressed skeletal muscle mitochondria; thus, we hypothesize rs671 polymorphism-promoted functional loss of may induce deleterious effects human muscle. aimed to clarify association polymorphism with phenotypes and athletic capacity a large Japanese cohort. A total 3,055 subjects, comprising 1,714 athletes 1,341 healthy control subjects...
Abstract Background Scaphoid excision and four-corner arthrodesis is an acceptable salvage procedure for the treatment of scapholunate advanced collapse (SLAC) scaphoid nonunion (SNAC) wrists, since first popularized in 1980s. We investigated potential application novel bioabsorbable plates screws made un-sintered hydroxyapatite/poly-L-lactide composite metacarpal fractures. used this material fixation fusions SLAC or SNAC wrists commencing from April 2009. The purpose study was to clarify...
We hypothesised that using a palmaris longus tendon ball (PLTB) with bone core (w bc) after excisional arthroplasty for Kienböck disease would maintain post-operative carpal height compared to PLTB without (w/o bc). Seventeen hands of 16 consecutive patients at Lichtman stage IIIA or IIIB were treated by replacement the lunate w bc w/o bc. evaluated clinical and radiological outcomes one, three 12 months surgery. According Dornan criteria respectively, there no significant differences...
An 83 year-old Japanese woman complained of left lateral thigh pain following a low-energy fall 4 months prior to admission. She had been treated for osteoporosis with Risedronate and Alfacalcidol the previous five years. was diagnosed an atypical femoral fracture (AFF) according American Society Bone Mineral Research (ASBMR) Task Force revised criteria. Radiographs revealed cortical thickening transverse radiolucent line in cortex shaft. MRI showed high intensity signal on T2WI image 1 cm...
Fibrosis of the subsynovial connective tissue (SSCT) is a characteristic finding in patients with idiopathic carpal tunnel syndrome (CTS). Idiopathic CTS frequently occurs postmenopausal women; therefore, female steroid hormones, especially estrogens, may be involved its development. In this study, we evaluated effect estradiol on expression genes and proteins related to fibrosis SSCT fibroblasts from CTS. This study included 10 women (mean age 76 years). Fibroblasts derived were treated (10...
Mechanical unloading induces bone loss in human weight-loaded bones. The findings of recent studies have revealed that cluster differentiation 38 knockout mice display similar to observed osteoporosis. This study aimed determine whether the expression is implicated skeletal and reloading.Eight-week-old male C57BL/6J were assigned control, tail-suspension, or reloading after tail-suspension groups. In group, tail suspension elevated hind limbs for 1 week. bilateral femurs tibias from groups...
Hand osteoarthritis (OA) has a wide spectrum of clinical presentations and physical function is one the core domains where patients suffer. The Functional Index for Osteoarthritis (FIHOA) leading assessment tool hand OA-related functional impairment. Our objective was to make Japanese version FIHOA (J-FIHOA) validate it among OA patients.Forward backward translation processes were completed create culturally adapted J-FIHOA. A prospective, observational multicenter study undertaken...
We examined 6 cases of tendon injuries that accompanied distal radius fractures using volar locking plate between April 2006 and March 2012. Male: one case, female: five cases, average age 57.0 (33~70) years old. The fracture type was A2 in A3 four C2 case by AO classification. period for operation waiting 2.7 days. analyzed the time occurrence rupture (extensor pollicis longus (EPL)･flexor (FPL)), existence or not screw prominence dorsal roof fragment, positioning setting. ruptures were EPL...
