The FDL was transected at the level of the proximal interphalangeal joint, passed plantar-to-dorsal through a drill hole centrally located in the base of the proximal phalanx, and sutured to the tendon of the EDL (Fig.
TABLE 2 Static 2-point discrimination for hand and wrist (14,15) Distance in mm Location Normal Diminished Absent Distal to DIPJ 3-5 6-10 10+ Between DIPJ and PIPJ 3-6 7-10 10+ Central palm 6-9 10-20 20+ Base of palm and wrist 7-10 11-20 20+ DIPJ, distal interphalangeal joint; PIPJ, proximal interphalangeal joint.
Involvement of 1-3 "small" joints (defined as metacarpophalangeal joints, proximal interphalangeal joints, second to fifth metatarsophalangeal joints, thumb interphalangeal joints, and wrists) gets 2 points, regardless of large-joint involvement; involvement of 4-10 small joints gets 3 points.

X-Ray made on lumbar spine, hands, feet and pelvis showed: multiple osteosclerotic oval-round lesions with a maximum diameter of 10 mm, without osteolysis, with a benign character and with a periarticular localization at the level of the fist, metacarpophalangeal joints, proximal interphalangeal joints, coxofemoral joints, peritarsal, metatarsophalangeal and interphalangeal joints.
