dislocation of the thumb carpometacarpal joint is a rare injury, and only 38 cases have been definitively described in the english-speaking literature. all the reported dislocations have been dorsal. we present a volar form of the thumb carpometacarpal dislocation which was managed surgically after three months from the injury with open reduction and volar ligament reconstrction, with satisfact...

Finger-thumb coordination is crucial to manual dexterity but remains incompletely understood, particularly following neurological injury such as stroke. While being controlled independently, the index finger and thumb especially must work in concert to perform a variety of tasks requiring lateral or palmar pinch. The impact of stroke on this functionally critical sensorimotor control during dyn...

PURPOSE OF THE STUDY Arthrodesis of the carpometacarpal (CMC) joint of the thumb is an option for treatment of degenerative and post-traumatic conditions affecting the CMC thumb joint. This procedure is indicated most frequently in patients with primary or secondary stage III rhizarthritis (by the Eaton classification of basal joint arthritis) of idiopathic, rheumatic or post-traumatic etiology...

BACKGROUND Sick leave is a topical subject, particularly following the revision of the Agreement on a More Inclusive Working Life (the IA agreement). However, there has been little discussion about the extent to which sick leave may be related to work. MATERIAL AND METHODS The paper is based on a non-systematic literature search using PubMed combined with personal research and experience. R...

BACKGROUND Identifying highly sensitive and reliable neurological exam components are crucial in recognizing clinical deficiencies. This study aimed to investigate finger tapping performance differences between patients with CNS demyelinating lesions and healthy control subjects. METHODS Twenty-three patients with multiple sclerosis or clinically isolated syndrome with infratentorial and/or c...

This study evaluated the generalization, maintenance, and negative side-effects of Habit Reversal (HR) and Differential Reinforcement of Other Behaviour (DRO) in the elimination of thumb-sucking. Thirty children who sucked their thumbs or fingers excessively were randomly assigned to a HR, DRO or wait-list control group. Observation data were collected in three observation settings. Both proced...

Background Acute ruptures of the ulnar collateral ligament (UCL) of the thumb are common injuries in sports. Surgical repair has yielded excellent results and high return-to-sport (RTS) rates in elite athletes. Purpose To determine (1) the RTS rate in Major League Baseball (MLB) players following thumb UCL repair, (2) postoperative career length and games played per season, (3) pre- and posto...

abstract a solitary plasmacytoma of bone occurs in approximately 2-5% of patients with myeloma. the lesion mostly found in the axial skeleton and have infrequently been reported to arise in the hand, and usually occur in the distal phalanges. we report the interesting case of a 75-year-old man who developed a solitary lytic lesion of the thumb proximal phalanx. this lesion was explored through ...

The human opposable thumb enables the hand to perform dexterous manipulation of objects, which requires well-coordinated digit force vectors. This study investigated the directional coordination of force vectors generated by the thumb and index finger during precision pinch. Fourteen right-handed, healthy subjects were instructed to exert pinch force on an externally stabilized apparatus with t...
