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)...
Abstract Background The acromioclavicular (AC) and coracoclavicular (CC) ligaments are important stabilizers of the AC joint. We hypothesized that trapezoid ligament injuries induce joint instability clavicle can override acromion on cross-body adduction view even in absence conoid injury. Accordingly, we investigated how sectioning CC contribute to position. Methods Six fresh-frozen cadaveric shoulders were used this study, comprising five male one female specimen, with a mean age 68.7...
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...
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...
Abstract Background The relationship between acromioclavicular (AC) joint dislocation, corresponding radiological evaluation, and ligament injuries remains controversial. We hypothesized that AC trapezoid induce instability, the clavicle can override acromion on cross-body adduction view without conoid injury. aimed to investigate how biomechanically sectioning coracoclavicular (CC) ligaments contributes instability in position using fresh-frozen cadaver models. Methods Six cadaveric...
Case: A 24-year-old professional judo competitor suffered injuries to both the wrists when he fell on his back while lifting a 90-kg barbell in bilateral dorsiflexed wrist position. Simultaneous volar lunate dislocation had been missed for year. The degenerated lunates were simultaneously removed using palmar approach. At 12 months postoperatively, patient returned competitions without pain. Radiography showed no progression of intercarpal alignment abnormality. Conclusion: chronic is...
