[en] Hallux rigidus is an osteoarthritic degeneration of the first metatarsophalangeal joint characterized by the formation of a dorsal osteophytic prominence and loss of sagittal plane mobility, resulting in pain and limitations in activity and quality of life for affected individuals. It tends to occur more frequently in female patients and typically manifests after the fifth decade of life. Among the various therapeutic options for hallux rigidus, Moberg osteotomy, commonly associated with cheilectomy, has shown promising results with a low rate of complications. The objective of this systematic review was to evaluate the effectiveness of Moberg osteotomy in the treatment of hallux rigidus, establish significant associations between study variables, and determine the appropriate patient profile for benefiting from this intervention. METHODOLOGY: A literature search was conducted in the databases PubMed, Scopus, Web of Science, Cochrane, ProQuest, and Google Scholar using the terms "Hallux Rigidus," "Stiff toe," "Moberg Osteotomy," "Kessel-Bonney osteotomy," "Phalangeal Osteotomy," "Phalangeal dorsiflexory osteotomy," and "Proximal phalanx closing wedge ostetomy" in combination with Boolean operators AND and OR. After removing duplicates and screening references based on inclusion and exclusion criteria, five articles were selected. RESULTS: A total of 295 patients (296 interventions) with a mean age of 54.6 years, of whom 70% were female, were included in the analysis. The mean follow-up period was 4.62 years. According to the Coughlin and Shurnas classification, 32.31% were grade II, 29.23% were grade III, and 38.46% were grade IV. There was a significant relationship between increased width of the resected bone wedge and higher grade of hallux rigidus, lower AOFAS score, and higher VAS pain level. The range of dorsiflexion increased by a mean of 17.8°, while the range of plantarflexion decreased by a mean of 15.5°. The percentage of complications and revision surgeries was 14.14%. AOFAS, VAS, MOxFQ, and PROMIS scores improved postoperatively. Satisfaction was excellent in 74% of cases, and footwear limitations persisted in 9 out of the 15 cases evaluated. CONCLUSION: Moberg osteotomy has proven to be an effective and safe technique in the treatment of mild to moderate hallux rigidus, with a low rate of associated complications. It can be considered as a conservative alternative for well-selected patients with advanced hallux rigidus who are candidates for arthrodesis, aiming to preserve joint mobility. However, evidence is limited, and many issues need to be studied more rigorously to establish a solid understanding in this field.

[gl] O hallux rigidus é unha dexeneración osteoartrítica da primeira articulación metatarsofalánxica caracterizada pola formación dunha prominencia osteofítica dorsal e a perda de mobilidade no plano saxital, o que provoca dor e limitacións na actividade e na calidade de vida das persoas que o sofren. Esta suxeito a presentarse con máis frecuencia en pacientes de xénero feminino e a partir da quinta década de vida. Entre as diversas opcións terapéuticas para o hallux rigidus, a osteotomía de Moberg, comúnmente asociada á queilectomía, mostrou resultados prometedores cunha cifra baixa de complicacións. O obxectivo desta revisión sistemática foi avaliar a efectividade da osteotomía de Moberg no tratamento do hallux rigidus, establecer asociacións significativas entre as variables do estudo e determinar o perfil de paciente máis adecuado para beneficiarse desta intervención. METODOLOXÍA: Realizouse unha busca bibliográfica nas bases de datos PubMed, Scopus, Web of Science, Cochrane, ProQuest e Google Scholar utilizando os termos "Hallux Rigidus", "Stiff toe", "Moberg Osteotomy", "Kessel-Bonney osteotomy", "Phalangeal Osteotomy", "Phalangeal dorsiflexory osteotomy" e "Proximal phalanx closing wedge ostetomy" en combinación cos operadores booleanos AND e OR. Tras eliminar duplicados e revisar as referencias segundo os criterios de inclusión e exclusión acordados, seleccionáronse cinco artigos. RESULTADOS: Contabilizáronse un total de 295 pacientes (296 intervencións) cunha idade media de 54,6 anos, dos cales o 70% eran mulleres. O seguimento medio foi de 4,62 anos. Segundo a clasificación de Coughlin e Shurnas, o 32,31% eran de grao II, o 29,23% de grao III e o 38,46% de grao IV. Observouse unha relación significativa entre o aumento da largura da cuña ósea resecada e un maior grao de hallux rigidus, menor puntuación AOFAS e maior nivel de dor VAS. O rango de DF aumentou unha media de 17,8° e o rango de PF diminuíu unha media de 15,5°. O porcentaxe de complicacións e intervencións de revisión foi do 14,14%. As puntuacións AOFAS, VAS, MOxFQ e PROMIS melloraron despois da cirurxía. A satisfacción foi excelente no 74% dos casos e as limitacións no calzado mantivéronse en 9 dos 15 casos avaliados. CONCLUSIÓNS: A osteotomía de Moberg demostrou ser unha técnica efectiva e segura no tratamento do hallux rigidus de grao leve e moderado, mostrando unha cifra reducida de complicacións asociadas. Pode ser unha alternativa conservadora en pacientes con HR avanzado ben seleccionados candidatos á artrodesis co fin de preservar a mobilidade articular.
