Table 1
Comparison of occipitocervical fusion patient groups
	Revision	No revision	p
N	11 (10%)	96 (89%)	−
POCA	Mean: 109.5 Range: 72–123	Mean: 107.1 Range: 85–141	0.23
	Revision (excluding infection as indication)	No revision
Adjacent level disease	2 (1.8%)
Instrumentation failure	5 (4.7%)
Total	7 (6.5%)	94 (88%)
POCA (degrees)	Mean: 115 Range: 80–136	Mean: 107.1 Range: 85–141	0.039

Note: When patients who underwent revision surgery for reasons other than infection (adjacent segment degeneration or instrumentation failure), a significantly higher POCA (115 degrees, n = 0.039) was found.
