<b>Background</b> The purpose of this article was to review the anatomy, kinematics distal radioulnar joint (DRUJ), and discuss definition, classification, diagnosis DRUJ instability. <b>Methods</b> A biomechanical perspective on physical examination ballottement test documented. Physiological dynamic translation differences following sequential ligament sectioning changes in different forearm wrist positions were demonstrated. clinical significance each ligament's contribution stability...
We investigated the reliability and accuracy of distal radioulnar joint (DRUJ) ballottement test using five fresh-frozen cadaver specimens in triangular fibrocartilage complex (TFCC)-intact, TFCC-sectioned wrists. The humerus proximal ulna were fixed. was allowed to translate dorsopalmar directions without rotation, radius move freely. Four sensors a magnetic tracking system attached ulna, nails each examiner's thumbs. Five examiners conducted DRUJ before after TFCC sectioning. used two...
Wide-awake hand surgery is useful for tendon reconstruction because surgeons can observe the actual movement of reconstructed tendons during surgery. We hypothesized that accurate ultrasound-guided injection local anesthetics into sensory nerves contributes to reliable analgesia with a relatively small amount anesthetic.We enrolled 8 patients who underwent forearm transfer. Three flexor ruptures in zones 4 and 5, 3 opponensplasty, 2 multiple transfers according Brand's procedure. All...
Bone marrow stromal cells can be applied therapeutically to enhance angiogenesis; however, the use of bone cell suspensions reduces efficiency because low-level attachment. The authors hypothesized that sheets would facilitate fixation, thus enhancing angiogenesis. investigated flap survival area and enhancement angiogenic factors in a rat random-pattern skin model after application sheets.Bone (prepared from 7-week-old femurs) were cultured under four different hypoxic conditions. Sheets...
To examine the clinical outcomes of arthroscopic lunate excisions for advanced Kienböck's disease.Fifteen patients (six men and nine women; mean age: 65 years; range: 48-83 years) with disease, who underwent resection between April 2008 March 2016, were reviewed clinically radiographically after a follow-up >2 years (mean: 29 months; 24-60 months). Clinical parameters, such as wrist range motion, grip strength, Disabilities Arm, Shoulder, Hand (DASH) score, patient-rated evaluation (PRWE)...
An 11-year-old girl with Kienböck disease (stage IIIA) was treated by temporary scaphotrapeziotrapezoidal fixation. It fixed in a cast for four weeks and wires removed after eight weeks. Follow up examinations showed that movement of the wrist grip strength were improved, she had no pain while revascularisation lunate could be seen on magnetic resonance imaging.
Anterior dislocation of the ulnar nerve is occasionally encountered after simple decompression for treatment cubital tunnel syndrome. The purpose this study was to determine whether incidence following correlated with patient's preoperative characteristics and/or elbow morphology. We studied 51 patients syndrome who underwent surgery at our institution. Intraoperatively, we simulated by flexing releasing in each patient. Univariate and multiple logistic regression analysis showed that young...
Septic arthritis of the wrist is rare entity, especially; atypical mycobacterial infection extremely rare. We report a case septic caused by Mycobacterium intracellulare, which was successfully treated radical debridement followed arthrodesis using vascularised fibular grafting.
Abstract Background Cubital tunnel syndrome can be caused by overtraction and dynamic compression in elbow deformities. The extent to which deformities contribute ulnar nerve strain is unknown. Here, we investigated cubitus valgus/varus deformity using fresh-frozen cadavers. Methods We used six cadaver upper extremities. A gauge was placed on the 2 cm proximal medial epicondyle of humerus. For model, osteotomy performed at distal humerus, plate fixation create (10°, 20°, 30°). Ulnar flexion...
Background: Functional outcomes of patients who underwent arthroscopy-assisted surgery for trapeziometacarpal osteoarthritis were reported. Methods: We included 24 consecutive (6 males and 18 females) postoperative hand therapy at our hospital between April 2012 March 2018. For functional evaluation, we used the Purdue Pegboard Test (PPT), grip pinch strength, range motion thumb, visual analogue scale (VAS) thumb pain, Quick Disabilities Arm, Shoulder Hand (QuickDASH) Japanese version...
A few treatment options for radial neck non-union have been reported, including head excision, replacement, and internal fixation with a bone graft. We describe new using reverse vascularized graft of the lateral distal humerus. In anatomical study, posterior collateral artery (PRCA) was dissected in eight fresh-frozen cadaver arms. The number branches from PRCA to humerus determined, distances these epicondyle were measured. then used this information create vascularizedhumeral graft, which...
The most common procedure for the treatment of painful median nerve neuroma is coverage with vascularized soft tissue following external neurolysis. However, ideal should include reconnecting proximal and distal stumps damaged to allow growth regenerating axons their proper targets a functional recovery. We developed useful technique employing radial artery perforator adipofascial flap including lateral antebrachial cutaneous (LABCN) repair by grafting achieve tissue. In an anatomical study...
There is a lack of data on how ulnar nerve strain varies according to the location around elbow joint. Therefore, we measured longitudinal movement Four fresh-frozen cadaveric upper extremities were used. A linear displacement sensor was attached at eight measurement points 20-mm intervals. At each point, during flexion. We calculated based change in between neighboring points. Ulnar with flexion had maximum value (mean, 10.5 mm; p < 0.001) 2 cm proximal medial epicondyle. In site distal...
Background The peroneal artery perforator-based flap has been widely used as a pedicled propeller for soft tissue reconstruction in the lower extremity; however, its application free rarely reported. We report on utility of finger reconstruction. Methods Twelve patients underwent reconstructions defects with flaps. were located either dorsally and/or laterally fingers. size flaps ranged from 5 × 2 to 8 3 cm. length vascular pedicles 4 and vein perforator vessels anastomosed digital...
