The tendon of the extensor secundi internodii,indeed, can be followed up to its insertion at the base of theterminal phalanx. Unfortunately many of the fainter records arelost in reproduction. Hand. As anticipated, the Rbntgen ray methods have shown that meta-carpal fractures are more common than was formerly supposed.There is usually little displacement, since the adjoining metacarpalbones act as efficient splints. In some cases where there is lateral displacement, union in a badposition may lead to much deformity and loss of function. Reductionis always easy if the exact nature of the injury be known; it istherefore desirable in such cases to examine the fracture by meansof the Rontgen rays. A good account of this injury is given by Dr. Carl Beck,* of * Treatment of Fracture of the Metacarpal Bones, Carl Beck, M.D., NewYork MedicalJournal, August 4, 1900, p. 177. 208 THE RONTGEN RA YS IN MEDICAL WORK

He describes a case in which a man sustained fractureof the fourth metacarpal in striking a blow with his fist.* Dr. Beck treats these fractures by a simple splint made of tworubber drainage-tubes lightly pressed into the adjoining interos-seous spaces, and kept in position by strips of plaster passed roundthe hand. Dr. G. T. Beatson, of Glasgow, has published an excellent illus-tration of the so-called stave of thumb, or Bennetts fracture. Thefracture is an oblique detachment of the palmar half or more of thearticular surface of the metacarpal bone facing the trapezium, while,in addition, the entire metacarpal bone, except the little piece ofthe base so separated, has slipped backwards, no doubt through theaction of the extensor ossis metacarpi and other muscles, and thissimulates a dislocation of the bone in that direction.
