RESUMEN
Scaphoid fractures are a common wrist injury accounting for 2-7% of all adult fractures. Nonunion is described in 5-12% of cases leading to osteoarthritis. Several classifications have been developed focused on this pathology and its complication. We present a case of a 28 years old male patient with a scaphoid fracture and nonunion who spontaneously consolidates without treatment. We performed a literature review to recognize this pathology, its common evolution and possible treatment options.
Las fracturas de escafoides son una lesión frecuente de la muñeca y representan de 2-7% de todas las fracturas en adultos. La no unión se describe en 5-12% de los casos y conduce a la osteoartritis. Se han desarrollado varias clasificaciones centradas en esta patología y su complicación. Presentamos el caso de un paciente varón de 28 años con fractura y no unión de escafoides que consolida espontáneamente sin tratamiento. Realizamos una revisión bibliográfica para reconocer esta patología, su evolución habitual y las posibles opciones de tratamiento.

The aim of the present study was to evaluate long-term functional and radiographic outcome in the distal radioulnar joint (DRUJ) for Galeazzi fracture-dislocation after anatomic reduction and rigid fixation of the radius. Fourteen patients, with an average age of 38 years, presenting with Galeazzi fracture-dislocation treated by open reduction and internal fixation (ORIF) of the radius and closed reduction of the DRUJ were retrospectively evaluated, with a minimum follow-up of 6 years. At final evaluation (mean: 8 years), the DRUJ was objectively and subjectively evaluated for range of motion (RoM), grip strength, ballottement test, pain on axial loading, function on visual analog scale (VAS) and DASH score. Radiographs and dynamic CT scans were performed to screen for DRUJ instability and/or osteoarthritis. Six of the patients had a positive comparative ballottement test, but none reported pain during the maneuver. No significant differences in RoM were found between the injured and uninjured wrist. Mean grip strength in the injured wrist was 77% of the contralateral value. Mean pain on VAS was 0.6. Mean global function on VAS was 9. Mean DASH score was 3. Dynamic CT showed no clear subluxation in any of the patients, and none showed severe articular changes. Our findings suggest that long-term clinical and radiological prognosis for the DRUJ in Galeazzi lesions is favorable when adequate closed reduction of the ulna is achieved after anatomical ORIF of the radius. LEVEL OF EVIDENCE: IV. Therapeutic case series.
