TY - JOUR PY - 1986// TI - Breakdancer's thumb--partial rupture of the ulnar collateral ligament with a fracture of the proximal phalanx of the thumb JO - Injury A1 - Winslet, M. C. A1 - Clarke, N. M. A1 - Mulligan, P. J. SP - 201 EP - 202 VL - 17 IS - 3 N2 - Breakdancing is an acrobatic dance that involves spinning on various parts of the body including the head, dorsal spine and hand. Three cases are reported of partial rupture of the ulnar collateral ligament (UCL) of the thumb, associated with a fracture of the base of the proximal phalanx which occurred as a result of torsional forces applied to the abducted and hyperextended thumb. It appears to be a distinct clinical entity. In all cases, open reduction was required and led to excellent functional recovery. LA - SN - 0020-1383 UR - http://dx.doi.org/ ID - ref1 ER -
