Periosteal resorption of finger phalanges: radial versus ulnar surfaces.

Measurement of periosteal resorption (PR) at the radial and ulnar surfaces of the second, third and fourth middle phalanges of one hand in 60 normals and 61 chronic renal failure (CRF) patients showed generally higher involvement at the radial than the ulnar surfaces; however, best diagnostic results were achieved when PR was measured at both radial and ulnar surfaces of the index finger only. With the quantitative method, 31 of 61 CRF patients showed changes, whereas only 22 were identified with the grading method.

The dorsal middle phalangeal finger flap.

A versatile one-stage neurovascular flap from the dorsum of the middle phalanx of the finger is described. The flap is based on one proper digital artery, the venous network about its adventitia and the dorsal branches of the proper palmar digital nerves bilaterally. The characteristics of the flap include a size up to 3 by 6 cm, an arterio-venous pedicle up to 12 cm in length, an arc of rotation around the superficial palmar arch, discriminative sensibility, and comparably low donor morbidity. The flap may be transposed on its vascular pedicle with or without nerve suture. Furthermore it is ideally suited as a thin and pliable flow-through flap in digital replantation/revascularization. Finally, it may be utilized as a free neurovascular flap.
