Wrist Arthrodesis in Rheumatoid Arthritis Using an LCP Metaphyseal Locking Plate versus an AO Wrist Fusion Plate

Table 3

Radiographic measurements. (a) Comparison of immediately after surgery versus the most recent follow-up. (b) Comparisons of the AO wrist fusion plate and the LCP metaphyseal plate groups.

(a)

	AO wrist fusion plate (n = 9)			LCP metaphyseal plate (n = 7)
	Immediately after surgery	Most recent F-U	P value	Immediately after surgery	Most recent F-U	P value
WE angle (degrees)	13.9 (10–18)	14.4 (10–18)	0.72	21.4 (16–24)	20.6 (16–27)	0.67
Ulnar deviation angle (degrees)	7.2 (2–15)	8.7 (2–15)	0.11	12.3 (3–21)	12.3 (7–20)	> 0.99

LCP, locking compression plate; F-U, follow-up; WE, wrist extension.

(b)

	AO wrist fusion plate; (n = 9)	LCP metaphyseal plate; (n = 7)	P value
|∆WE angle| (degrees)	3.0 (0–5)	3.6 (2–6)	0.57
|∆Ulnar deviation angle| (degrees)	1.8 (0–5)	3.0 (0–5)	0.28
Distance between MC head; to distal end of plate (mm)	2.1 (1.5–3.2)	2.8 (2.5–3.4)	0.005

LCP, locking compression plate; WE, wrist extension; MC, metacarpal.
