“…This would benefit pathologies such as scaphoid proximal pole nonunion or Kienbock where the vascular aspect is compromised. 8 This theoretical framework is reinforced by the study of Sherman et al, 15 where they demonstrated that the metaphyseal core decompression does not alter the forces transmitted through the radiocarpal joint. In their study of radius osteotomies for Kienbock disease treatment, Kam et al 16 concluded that the mechanical discharge obtained would not be the physiological basis through which the osteotomy acts; rather, they stated that a fibrovascular stimulus secondary to this gesture would be the basis for the success of the osteotomies in the treatment of this pathology.…”

Objective To report the consolidation rate and the results of a series of 22 patients with metaphyseal core decompression of the distal radius and an antegrade compression screw. Methods We present a prospective series of patients with scaphoid proximal pole nonunion in whom the presence of intraoperative bleeding was confirmed in both fragments. Patients with displacement, degenerative changes, fragmentation of the proximal pole, cavitation of the focus, loss of height, and necrosis, as well as those with carpal instability, were excluded. The patients were evaluated with X-rays and computed tomography to evaluate their consolidation; their mobility and fist strength were recorded and an analog visual scale (VAS) of pain at rest, pain in activity, subjective functional status, and DASH questionnaire were completed. Results Of the 23 patients, 21 accomplished union. The average follow-up was 19 months and the average final range of motion was flexion 86%, extension 85%, radial deviation 79%, ulnar deviation 84%, and grip strength 84%. The average VAS for pain at rest was 1 point, the average VAS for activity pain was 2 points, the average VAS for function was 9 points, and the average DASH score was 8. Conclusions Using this simple and reliable technique, we obtained 91% union and very good functional results. Metaphyseal core decompression of the distal radius associated with an antegrade scaphoid screw is a reasonable and effective option for the treatment of proximal pole scaphoid nonunions without avascular necrosis in carefully selected patients. Level of Evidence This is Level IV study.

“…7 Este marco teórico es reforzado por el estudio de Sherman y cols. 15 en el que demostraron que el BOM no altera las fuerzas transmitidas a través de la articulación radio-carpiana. Kam y cols., 16 en su estudio de osteotomías de radio para el tratamiento de la enfermedad de Kienböck, concluyeron en que la descarga mecánica obtenida no sería el fundamento fisiológico a través del cual actuarían, sino que un estímulo fibrovascular secundario a dicho gesto sería el fundamento del éxito de las osteotomías en el tratamiento de dicha patología.…”

Objetivo: Reportar la tasa de consolidación y los resultados de una serie de 22 pacientes con seudoartrosis del polo proximal del escafoides tratados con un bloqueo óseo metafisario asociado a un tornillo autocompresivo anterógrado.Materiales y Métodos: Serie prospectiva de pacientes con seudoartrosis del polo proximal del escafoides en quienes se constató un sangrado intraoperatorio en ambos fragmentos. Se excluyó a los pacientes con desplazamiento, cambios degenerativos, fragmentación del polo proximal, cavitación del foco, pérdida de altura, necrosis y aquellos con inestabilidad carpiana. Se tomaron radiografías e imágenes por tomografía computarizada para evaluar su consolidación; se registraron la movilidad y la fuerza de puño, y los pacientes completaron una escala analógica visual para dolor en reposo, dolor en actividad, estado subjetivo funcional y el cuestionario DASH.Resultados: La serie incluyó 18 pacientes. Diecisiete presentaron consolidación. El seguimiento promedio fue de 22 meses y la movilidad final promedio fue: flexión 87%, extensión 84%, desviación radial 78%, desviación cubital 84% y fuerza de puño 85%. El puntaje promedio de la escala analógica visual fue 0 para dolor en reposo; 2, para dolor en actividad y 9 para función, en tanto que el puntaje DASH promedio fue de 8.Conclusiones: Con esta técnica confiable y sencilla, obtuvimos una tasa de consolidación del 95% y un muy buen resultado funcional. El bloqueo óseo metafisario asociado a un tornillo anterógrado constituye una alternativa válida y eficaz para tratar la seudoartrosis del polo proximal del escafoides, vital en pacientes cuidadosamente seleccionados. ABSTRACTObjective: To report the consolidation rate and the outcomes of a series of 22 patientswith proximal pole scaphoid nonunion treated with a metaphyseal core decompressionand an anterograde self-compressing screw.Methods: We present a prospective series of patients with proximal pole scaphoidnonunion and confirmation of intraoperative bleeding in both fragments. Patientspresenting with displacement, degenerative changes, proximal pole fragmentation,cavitation at the fracture site, reduced bone length, and necrosis, as well as those withcarpal instability, were excluded. X-rays and computed tomography scans wereperformed to assess consolidation; range of motion and grip strength were recorded, andpatients completed a visual analogue scale for pain at rest, pain during activity, andsubjective functional status, as well as a DASH (Disabilities of the Arm, Shoulder andHand) questionnaire.Results: Eighteen patients were included. Union was observed in 17 patients. Theaverage follow-up time was 22 months, and the average final range of motion was asfollows: 87% for flexion, 84% for extension, 78% for radial deviation, 84% for ulnardeviation, and 85% for grip strength. The average score on the visual analogue scalewas 0 for pain at rest, 2 for pain during activity, and 9 for function, while the averageDASH score was 8.Conclusions: Using this simple and reliable technique, we obtained a 95% union andvery good functional results. Metaphyseal core decompression with an antegrade screwis a valid and effective alternative for treatment of proximal pole scaphoid nonunion incarefully selected patients.

“…After osteotomies, bone union difficulty and DRUJ dysfunctions are encountered [16,18]. Core decompressions of the distal radius and lunate for the treatment of Kienböck's disease represent two less invasive procedures with potentially fewer complications [19,20].…”

The Proposal and Early Results of Capitate Forage as a New Treatment Method for Kienböck's Disease

Kienböck's disease is a type of avascular necrosis which disrupts the biomechanics of the wrist as a result of the changes it creates in the lunate bone. Its treatment generally consists of osteotomies intended to relieve the pressure on the bone, pedicle bone grafting applications aiming to increase bone blood supply, and salvage procedures. Capitate forage is a safe and simple-to-apply surgical treatment method which is intended to enhance neovascularization of the lunate much like a radius osteotomy or core decompression.
