THE EFFECT OF COMPARTMENT SYNDROME AND FASCIOTOMIES ON THE HEALING OF CLOSED TIBIAL DIAPHYSEAL FRACTURES

Abstract

Aim: To evaluate the effect of fasciotomies following compartment syndrome on the healing of closed tibia diaphyseal fractures.

Patients and Methods: Between January 2002 and January 2005 165 patients were treated in our institution with closed tibial diaphyseal fractures. Patients were divided in to two groups; Group A (study group) consisted of patients that, after surgery, developed compartment syndrome and were submitted to fasciotomies and group B (control group) of patients who underwent reamed IM nailing and did not require such intervention. Patients with open fractures, pathological fractures, revision surgery, severe brain injuries, prolonged ITU stay and severe co-morbidities were excluded. Fracture pattern, ISS score, smoking habits, drugs intake, mode of mobilization and additional procedures were prospectively documented. Fracture healing more than 24 weeks was defined as delayed union and over 36 weeks as non-union. All patients had been followed-up clinically and radiologically until fracture union.

Results: One hundred twenty five out of 165 patients fulfilled the inclusion criteria for this study. 30 patients were classified in group A and 95 in group B. 18 patients of group A required skin graft coverage after the fasciotomies. There was no difference between the two groups in terms of the studied parameters. 4 patients from group A and 1 from group B, went to non-union and required second procedures to achieve union. These patients were excluded from the final analysis. Delayed union occurred in 11(percentage) patients in group A and in 10 (percentage) patients in group B (P< 0.05). Overall, fracture healing was prolonged in the fasciotomy group but the difference was not statistical significant, 24.27 weeks (10 – 48) versus 22.19 (12 – 40), (P= 0.157) in group A and group B respectively.

Conclusions: Compartment syndrome and fasciotomies is associated with delayed fracture healing. Nevertheless, this delay was not statistically significant different.
