Sometimes when the tape breaks, it avulisiert a portion of the proximal phalanx of the tape attachment. First, the patients have pain and Punktschmerzhaftigkeit on the ulnar side of the thumb Metakarpalgelenks. Among the long-term complications include u. a. Weakness and instability of the joint. Diagnostic stress tests are performed radiographs stress tests to verify the radial deviation of the thumb; before the test is in some patients anesthesia required (infiltration of a local anesthetic). The examiner stabilizes the radial side of the metacarpophalangeal joint in the thumb and pulling at the distal thumb in a radial direction. Both thumbs are tested and compared the degree of looseness. Anteroposterior and lateral radiographs are taken to check for a avulsion fracture of the proximal phalanx out. Sometimes stress-rays are taken. Therapy thumb spica splint Occasionally operation Initial treatment is with immobilization by a thumb splint (thumb spica splint.) For several weeks. Surgery is sometimes necessary (for. Example, when instability occurs). After surgery, a thumb cast for 6 to 8 weeks is worn. Thumb spica splint.
