Short reportswere prominent epicanthic folds, bilateral ptosis, and optic atrophy. The ears were large, prominent, and low set. He had flexion deformities and limitation of movement at the proximal interphalangeal joints of all the digits but mainly the second, third, and fourth fingers bilaterally. The fingers were short and spindle-shaped, thickened at the proximal interphalangeal joint and tapering distally. The middle phalanges were shortened and the distal digital creases were absent on the second and fourth fingers bilaterally. Bilateral talipes equinovarus had been corrected surgically at the age of 27 months. The child had a ventricular septal dcefct. His genitalia were normal.Dermatoglyhs showed a, b, c, d, and t triradii and a distal loop in the interdigital area IV of both palms. Total a-b ridge count was 88 and atd angles were normal. G, C, and 0 banded chromosome preparations from peripheral blood lymphocyte cultures revealed a complex rearrangement between Y, 1, and 3. Breakpoints were identified at Ypl 1, 1q21, 3q23, and 3q25. The karyotype was interpreted as 46,X,t(Y;1;3)(Yqter--Ypll::lq21 1lqter; 1pter--1q21: :3q25-3qter:3pter---3q23:) (figure). Segment 3q23-q25 could not be accounted for. The

The excursion of the flexor tendons of the thumb and fingers was studied in ten fresh cadaveric upper limbs. For each centimetre of tendon movement, obtained by traction of the flexor tendons at the wrist, the angular changes of the digital articulations were measured; movement started at extension and proceeded to maximum flexion. A further five upper limbs were used to evaluate the effect of pressure over the musculotendinous area of the flexor tendons of the fingers and thumb. Pressure on the muscle bellies in the forearm causes movement of the tendons, different for each finger, with the accompanying digital flexion depends on the magnitude of the movement. On the basis of this anatomical study a test is described which may be beneficial in the diagnosis of pathology and trauma of the flexor tendons and, particularly, in the intraoperative evaluation of the quality of motion obtained during tenolysis.
