Minimally invasive plate osteosynthesis for distal radius fractures using a 3-point positioning technique

Table 1 Early postoperative radiological indicators were compared with those of the contralateral side

Index	Operation side	Contralateral side	t	P value
1Volar tilt	13.0 ± 1.1	13.0 ± 0.96	0.13	0.90
1Radial inclination	19.8 ± 1.3	19.8 ± 1.4	0.10	0.92
2Ulnar variance	0.84 ± 0.10	0.86 ± 0.12	0.832	0.41

¹Volar tilt and radial inclination are measured in degrees (degrees ± SD).

²Ulnar variance is measured in millimetres (mm ± SD).

Table 2 Wrist pain, Gartland-Werley score and disabilities of the arm, shoulder and hand score were followed up after operation, mean ± SD

Index	1POD 1	1POD3	1POD7	1POW3	Finally follow-up
VAS	4.8 ± 0.6	3.6 ± 0.8	2.5 ± 0.7	1.5 ± 0.7	0.7 ± 0.6
DASH score	-	-	-	11.6 ± 2.0	4.7 ± 1.3
Gartland-Werley score	-	-	-	12.0 ± 2.5	4.1 ± 1.1

¹POD: Postoperative day.

¹POW3: Postoperative 3 week.

DASH: Disabilities of the arm, shoulder and hand; VAS: Visual analog scale.

Table 3 Range of motion and grip strength at the last follow-up were compared with those of the contralateral side

Variable	Operation side	Contralateral side	t	P value
1Flexion	54.3 ± 1.9	55.8 ± 2.4	2.62	0.01
1Extension	60.9 ± 1.1	62.8 ± 1.5	5.48	< 0.0001
1Pronation	88.2 ± 1.3	89.2 ± 0.8	3.48	0.0009
1Supination	86.6 ± 1.4	87.6 ± 1.2	3.25	0.002
2Grip strength	21.9 ± 3.5	25.3 ± 4.7	3.09	0.003

¹Range of motion is in degrees (degrees ± SD).

²Grip strength is in kilogram-force (mean ± SD).
