A Cadaveric Anatomy Study of the Shape-Modified Radial Forearm Flap
Research article published in The Journal of hand surgery (2025)
Abstract
PURPOSE: Mateev developed a shape-modified radial forearm flap (SMRFF), the use of which is not widespread. This study aimed to analyze hand subunit defects and combinations thereof that can be reconstructed using the SMRFF. METHODS: An anatomical study of 10 injected cadavers was conducted to investigate the subunits and combinations reachable with SMRFF. The radial pedicle length, the number and locations of radial artery perforators, the skin flap's dimensions and surface area, and the number, dimension, and surface area of skin paddles were recorded. RESULTS: In all 10 cadavers, the dorsum, the palm, all combinations of palmar subunits, and both sides of the first webspace could be covered. Two dorsal proximal phalanges could be covered only when adjacent. The mean radial pedicle length was 19.3 cm. All perforators (diameter > 0.5 mm) were septocutaneous, ranging from 3 to 9 per artery (mean: 6.3). On average, there were two perforators in the proximal third of the forearm, 2.3 in the middle third, and two in the distal third. At the proximal third of the forearm, the mean distance between the lateral epicondyle and the perforator was 6.6 cm. At the middle third of the forearm, this distance was 11.8 cm. At the distal third of the forearm, the mean distance between the perforator and the radial styloid process was 4.3 cm. The mean flap surface area was 98.4 cm2, with 34.4 cm2 for proximal paddles, 28.2 cm2 for middle paddles, and 22.8 cm2 for distal paddles. CONCLUSIONS: The SMRFF can effectively reach various hand subunit defects, offering versatile coverage for palmar and dorsal regions, with detailed perforator and flaps measurements. CLINICAL RELEVANCE: This study investigates the anatomical feasibility of the SMRFF and demonstrates its adaptability, making it a potentially valuable tool in hand surgery.

Por qué esto importa para la hirudoterapia
Este estudio anatómico cadavérico disecó 10 cadáveres inyectados para mapear qué subunidades de la mano puede alcanzar un colgajo de antebrazo radial modificado en forma (SMRFF), registrando recuentos de perforantes (media de 6,3 por arteria radial, todos septocutáneos), una longitud media del pedículo de 19,3 cm y una superficie media del colgajo de 98,4 cm2, y concluyó que el SMRFF puede cubrir las regiones palmar y dorsal de la mano de manera versátil. Su conexión con la hirudoterapia es indirecta y previa: los colgajos libres y pediculados de este tipo son el contexto clínico donde a veces se necesitan sanguijuelas para rescatar transferencias congestionadas venosamente, pero este artículo es puramente sobre viabilidad anatómica y diseño del colgajo. La clara advertencia es que este es un estudio de cadáver/anatomía sin perfusión viva, sin pacientes y sin mención de terapia con sanguijuelas, por lo que no tiene peso de evidencia clínica para la hirudoterapia más allá de definir el territorio quirúrgico en el que el salvamento del colgajo puede llegar a ser relevante.
