The purpose of this retrospective study was to compare the remodeling capacity and functional outcome of palmarly and dorsally displaced pediatric radius fractures in the distal one-third.
Fifty-three children with a residual dorsal angulation of 15 degrees (range 10 degrees -28 degrees, +/-SD 5.32) and 31 children with a residual palmar angulation of 15 degrees (range 10 degrees -30 degrees, +/-SD 4.88) at fracture healing were re-examined clinically and radiologically with a median follow-up time of 10 years (range 5-15 years).
There was no difference in the remodeling capacity, palmar tilt, radial inclination, and ulnar variance between both groups at follow-up. Pain as well as flexion/extension of the wrist and pronation showed no difference in both groups. Palmarly displaced fractures showed a significantly higher restriction of supination ( p=0.01).
We conclude that remodeling of residual palmar angulation occurs to the same extent as it does in dorsal angulation. Functional outcome differs in forearm supination.
本回顾性研究的目的是比较小儿桡骨远端三分之一处掌侧和背侧移位骨折的重塑能力和功能结果。
对53例骨折愈合时残留背侧成角15度（范围10度 - 28度，标准差±5.32）的儿童和31例残留掌侧成角15度（范围10度 - 30度，标准差±4.88）的儿童进行了临床和放射学复查，中位随访时间为10年（范围5 - 15年）。
随访时两组之间的重塑能力、掌倾角、桡骨倾斜度和尺骨差异均无差异。两组的疼痛以及腕关节的屈伸和旋前均无差异。掌侧移位骨折的旋后受限明显更高（p = 0.01）。
我们得出结论，残留掌侧成角的重塑程度与背侧成角相同。前臂旋后的功能结果有所不同。
