Influence of volar margin of the lunate fossa fragment fixation on distal radius fracture outcomes: A retrospective series

Table 2 Outcomes in the unfixed group and fixed group during follow-up

Group	Fixed, n = 16	Unfixed, n = 22	P value
Wrist instability at 1, 3, and 6 mo			< 0.001
Instability, n (%)	4 (25)	19 (86.4)
DISI	4	19
VISI	0	0
Stability, n (%)	12 (75)	3 (13.6)
ERLF, n (%)			0.019
> 25°	0 (0)	10 (45.5)
≤ 25°	16 (100)	12 (54.5)
Disability of the wrist at 1 year
Mayo, mean ± SD	94.0 ± 5.7	68.0 ± 15.1	< 0.001
DASH, mean ± SD	4.6 ± 2.5	28.5 ± 19.5	< 0.001

ERLF: Effective radiolunate flexion; DASH: Disabilities of the arm, shoulder, and hand; DISI: Dorsal intercalated segment instability; VISI: Volar intercalated segmental instability; SD: Standard deviation.
