Table 3.
Patterns of spread in 72 patients who spread from one to two limbs spontaneously or after a separate trauma of the second extremity
| Pattern of spreada | Total (N = 72) | Spontaneous spread (N = 38) | Separate trauma (N = 34) |
|---|---|---|---|
| Contralateral, no. (%) | 38 (53) | 24 (63) | 14 (41) |
| Ipsilateral, no. (%) | 23 (32) | 13 (34) | 10 (29) |
| Diagonal, no. (%) | 11 (15) | 1 (3) | 10 (29) |
aPatterns of spread were significantly different between patients with spontaneous spread and spread after a separate trauma; χ 2(2) = 10.2; P = 0.006
