OBJECTIVE: To demonstrate that a commercially available pelvic binder the trauma pelvic orthotic device (T-POD) is an effective way to provisionally stabilise anterior-posterior compression type pelvic injuries.
METHODS: Rotationally unstable pelvic injuries were created in 12 non-embalmed human cadaveric specimens. Each pelvis was then stabilised first with a standard bed sheet wrapped circumferentially around the pelvis and held in place with a clamp. After recreating the symphyseal diastasis, the pelvis was stabilised with the T-POD. Reduction of the symphyseal diastasis was assessed by comparing measurements obtained via pre- and post-stabilisation AP radiographs.
RESULTS: The mean symphyseal diastasis was reduced from 39.3mm (95% CI 30.95-47.55) to 17.4mm (95% CI -0.14 to 34.98) with the bed sheet, and to 7.1mm (95% CI -2.19 to 16.35) with the T-POD.
CONCLUSIONS: Although both a circumferential sheet and the T-POD were able to decrease symphyseal diastasis consistently, only the T-POD showed a statistically significant improvement in diastasis when compared to injury measurements. In 75% of the cadaveric specimens (9 of 12), the T-POD was able to reduce the symphysis to normal (<10mm >diastasis). Both a circumferential sheet and the T-POD are effective in provisionally stabilising Burgess and Young anterior-posterior compression II type pelvic injuries, but the T-POD is more effective in reducing symphyseal diastasis.
