<p><strong>Objetivo: </strong>Describir y analizar una técnica de osteosíntesis palmar de radio distal con preservación del pronador cuadrado.</p><p><strong>Materiales y Métodos: </strong>Se revisaron, en forma retrospectiva, 24 pacientes operados con esta técnica (16 mujeres y 8 hombres; edad promedio 65 años). Doce fracturas eran de tipo A; 7, de tipo B y 5, de tipo C. La técnica quirúrgica consiste en practicar una incisión cutánea de 25 mm y profundizar hasta observar el pronador cuadrado. Sin seccionarlo, se realiza una disección de su borde distal, a fin de introducir la placa bloqueada volar por debajo del músculo. Se colocan los tornillos distales bajo visión directa y los tornillos proximales, en forma percutánea. La evaluación posoperatoria se llevó a cabo mediante análisis clínico-funcional y radiográfico.<strong></strong></p><p><strong>Resultados: </strong>En el último control, todos los pacientes presentaban signos clínicos y radiográficos de consolidación ósea. El puntaje en la escala DASH fue, en promedio, de 4,8. Se observó una inclinación palmar posoperatoria de la superficie articular del radio de 14,3º promedio y una inclinación radial de 26,3º promedio. No se detectaron complicaciones relacionadas con la fractura, el implante o la herida quirúrgica en ninguno de los controles posoperatorios.</p><p><strong>Conclusiones: </strong>Sin bien no existe bibliografía que demuestre que la técnica mininvasiva sea superior, sostenemos que el hecho de obtener resultados similares con ambos abordajes (mininvasivo y convencional) justifica llevar a cabo esta técnica con preservación del pronador cuadrado, sobre todo en los pacientes preocupados por el aspecto cosmético de la cicatriz.</p>

In this study, we performed osteosynthesis for a distal radius fracture using a minimally invasive approach for a patient with skin disorder of the forearm and obtained favorable results. This case report may provide new findings confirming the usefulness of this surgical approach for distal radius fractures. Blister formation on the right forearm was observed in a 53-year-old female who was diagnosed with a distal fracture of the right radius and underwent splinting in a local hospital, and she was referred to our hospital 2 days after the injury. Minimally invasive locking plate osteosynthesis was performed, and there was no skin lesion at this incision site. Postoperatively, there were no complications in soft tissues and the operative scar was almost unrecognizable. We reported volar locking plate osteosynthesis using the minimally invasive approach in a patient with skin disorder of the forearm. Such patients are rarely encountered. However, this minimally invasive approach is extremely useful for utilizing the advantages of volar locking plate fixation without being affected by the soft tissue environment.

Background: The Conventus Distal Radius System (DRS) is an intramedullary fixation scaffold inserted into the lateral aspect of the distal radius. The purpose of this study was to identify insertion site anatomy to illustrate risks associated with the minimally invasive nature of radial-sided implant application. Methods: Ten cadavers were utilized. Using fluoroscopy, the 1.1-mm Kirschner wire and template was introduced per manufacturer’s guidelines, access guide assembled, and dissection carried out to the superficial radial nerve (SRN) with preservation of the native location. The access guide marked the insertion location for the side-cut drill. This point was measured in relationship to structures nearby, including the SRN, brachioradialis (BR), lateral antebrachial cutaneous nerve (LABCN), and radial styloid (RS). Results: The large guide contacted the SRN in 4 of 10 cadavers and was volar to it in 6 of 10. When volar, the mean distance was 1.7 mm. The tip of the RS to the large access guide averaged 44.5 mm. The small guide contacted the SRN in 2 of 10, was volar to it in 4 of 10, and between the bifurcation in 4 of 10. When volar, the distance averaged 3.25 mm. When bifurcated, the distance from the small guide to both the dorsal and volar branches was 3.5 mm. The distance from the RS to the small guide averaged 37.8 mm. The LABCN was found in the field of dissection in 4 of 10 cadavers. Conclusions: Several structures are at risk during insertion of the Conventus DRS; thus, knowledge of the relevant anatomy of this minimally invasive approach is crucial to optimize outcomes and patient satisfaction, and to avoid nerve injury.

Background: Volar locking plates were increasing popular as treatment of distal radius fractures. Various distal forearm anatomical variants were encountered during surgery. Flexor carpi radialis brevis (FCRB) was one of the most common and relevant anatomical variants because of its close proximity to fracture site. Methods: This is a retrospective single-centre study. In a 3.5-year period from March 2015 to August 2018, 133 patients who suffered from distal radius fracture requiring volar wrist plating were identified. Operation records and clinical photos were reviewed. All patients were followed up for at least 1 year. Any complications were recorded. Results: 9 patients with FCRB variant were identified. The prevalence was 6.8%. Hypoplastic pronator quadratus were found in 5 cases out of the 9 cases. None of these cases had any neurovascular injuries. No complications were noted during follow-up at 1 year. Conclusions: In Chinese population with volar locking plate done for distal radius fracture, the prevalence of flexor carpi radialis brevis was 6.8%. Surgeons should be aware of the possibility of FCRB variant.
