A review of the manufacturing process and infection rate of 3D-printed models and guides sterilized by hydrogen peroxide plasma and utilized intra-operatively

Table 2 The five most common applications amongst our patient cohort are listed, together with their infection rate, need for re-operation, and average length of operation in minutes (mean ± SEM)

Operation performed	Mode of application	Number of cases	Cases with infection (%)	Need for re-operation	Average operation time (minutes ± SEM)
Reverse shoulder arthroplasty	Guide	14	0	N/A	169 ± 17
Mandible resection	Guide	10	2 (20%)	1 of 2	649 ± 52*
Pilon fracture ORIF	Model	9	1 (11.1%)	0 of 1	193 ± 17
Acetabular / pelvis fracture ORIF	Model	7	0	N/A	400 ±159
Tibial plateau ORIF	Model	6	0	N/A	122 ± 23

* Patients receiving mandible resection had significantly longer operation time than those receiving reverse shoulder arthroplasty, pilon fracture ORIF, and tibial plateau ORIF (p < 0.01). ORIF = open reduction and internal fixation
