Impact of Obesity and Underweight on Surgical Outcome of Lumbar Disc Herniation

Table 4

Recurrence and revision rate among difference weight groups.

Group	Patient satisfaction				Recurrence* (%)	Revision^# (%)
	Excellent (%)	Good (%)	Fair (%)	Poor (%)
Underweight	18 (75)	3 (12.5)	2 (8.3)	1 (4.2)	3 (12.5)	1 (4.2)
Normal	69 (85.2)	7 (8.6)	3 (3.7)	2 (2.5)	7 (8.6)	3 (3.7)
Overweight	45 (80.3)	7 (12.5)	3 (5.4)	1 (1.8)	6 (10.7)	2 (3.6)
Obese	37 (82.2)	4 (8.9)	3 (6.7)	1 (2.2)	7 (15.6)	3 (6.7)

∗Re-herniation: symptomatic recurrence of lumbar disc herniation.
^#Re-operation: revision surgery due to refractory recurrence.
