Dynamic high-resolution ultrasonography findings obtained in 34 extreme rock climbers with finger injuries were compared with those in 20 healthy volunteers. Thicknesses of the flexor tendon and A-2 flexor tendon pulley system were measured at the base of the proximal phalanx. The distance between the tendon and phalanx was evaluated with the finger in extension and in forced flexion as a measu...

Intratendinous ruptures of a flexor digitorum profundus tendon are rare in patients who do not have rheumatoid arthritis. A case of a patient with no history of autoimmune disease who suffered a traumatic rupture of the flexor digitorum profundus tendon to the ring finger in the mid-palm is reported.

The tendon sheath mechanism plays an important role in many robotic systems from surgical devices to robot hands. However, many unexpected properties such as nonlinear hysteresis and backlash, which appear in the tendon sheath system, cause major losses in force transmission. This report deals with the characterization of hysteresis phenomenon, which is attributed to the presence of frictional ...

Brown (I950) defined the features of the superior oblique tendon sheath syndrome and reported five cases. He postulated that the restriction in elevation of the affected eye in the adducted position was caused by a congenitally short anterior tendon sheath of the superior oblique muscle. As the eye moved into adduction, this ligament-like sheath became taut and strongly opposed the action of th...

The authors report on a rare case of multicentric giant cell tumor of the tendon sheath in the right index finger of a 76-year-old woman. In the present case, three lesions simultaneously arose at different sites in the same finger. Magnetic resonance imaging and intraoperative findings revealed no contiguity among the three lesions. A multicentric origin of the tumor is unusual. SICOT Online R...

BACKGROUND Disruption of the plantar plate of the lesser metatarsophalangeal (MTP) joints leads to significant instability. Despite the fact that plantar plate disorders are common, the best mode of treatment remains controversial with operative treatments having variable and somewhat unpredictable clinical outcomes. METHODS Lesser MTP joints from the second, third, and fourth toes from fresh...

An intratendinous ganglion of the hand is a rare entity, and only one case report of flexor tendon has been published in the English literature. We herein report two cases of an intratendinous ganglion occurring in the extensor digitorum communis and flexor digitorum superficialis tendon, respectively.

In the Case Report "Early Controlled Motion Following Flexor Tendon Graft" (July 1988), the authors gave an excellent overview of the physio­ logical rationale for early controlled motion. I must express my concern, however, at their conclusion as stated: "The good functional results achieved suggest that a rehabilitation regimen consisting of the palmar pulley sys­ tem, a PIP joint block, and ...
