ABSTRACT
PURPOSE:
To investigate the distribution and characteristics of fractures of bones of the hand on radiographs with respect to age and skeletal maturity of the fractured bone, and to identify predictors of surgery.METHODS:
This cross-sectional, retrospective study included children (≤ 18 years) with hand fractures who underwent radiographic examinations (2019-2021). Fracture location, presence of displacement (≥ 2 mm), angulation (≥ 10°), articular extension, and if skeletally immature, then physeal involvement and Salter-Harris grade were recorded. Mann-Whitney U, Kruskal-Wallis, Fisher's exact, and chi-square tests as well as logistic regression analyses were used.RESULTS:
Study group of 508 (350 boys, 158 girls; median age, 11.9 years) included 575 (63% phalangeal, 37% metacarpal, and 0.3% carpal) fractures. Younger children were more likely to sustain phalangeal and older children carpal and metacarpal fractures (median ages 10.8 vs 12.3 and 13.8 years, p < 0.001); and fractures of the small finger accounted for 50% of metacarpal and 43% of phalangeal fractures. Fracture displacement (12% vs 22%, p = 0.02) and angulation (25% vs 49%, p < 0.001) were more common with mature than immature bones. A third of immature bones had physeal involvement and the most common pattern was Salter-Harris type II (89%). Surgical intervention was uncommon (11%) and independent predictors were displacement (OR = 3.99, 95% CI 1.95-8.19, p < 0.001) and articular extension (OR = 5.11, 95% CI 2.00-13.07, p < 0.001).CONCLUSION:
While younger children were more likely to sustain phalangeal than metacarpal fractures and less likely to have displacement and angulation when compared to older children; only displacement and articular extension were significant independent predictors of surgery.Palabras clave
