We treated 567 cases of tibial fracture and experienced 21 cases of acute compartment syndrome between September 1988 and June 1994.

The purpose of this study is to analysis the initial degree of intracompartmental pressure and duration between the diagnosis and decompression, to evaluate the functional results and to discuss the complications.

The result obtained were as follows

1. Anterior intracompartmental pressure was ranged from 25mnHg to 81mmHg (average 43.4mmHg), and deep posterior intracompartmental pressure ranged from 19mmHg to 61mmHg (average 32.7mmHg).

2. Among the 21 cases, common peroneal neuropathy were developed in 19 cases. We experienced complete recovery in 5 cases, incomplete recovery in 13 cases and 1 case of no change. We found posterior tibial neuropathy in 8 cases, and experienced complete recovery in 2 cases, incomplete recovery in 5 cases and 1 case of no change.

3. As an complications, clawing of toe developed in 3 cases, equinovarus deformity of ankle in 2 cases, superficial wound infection, osteomyelitis and nonunion in 1 case.

4. We obtained good or excellent results in 16 cases(76.1%).

5. We thought that the most important factor to decide the prognosis seems to be duration of high level of tissue pressure and also it is neccessary early diagnosis and early treatments to obtain good results.
