Objective:
To explore the mechanism and feasibility of the supinator syndrome evoked embitterment test from anatomy and clinic.
Methods:
25 cases of The supinator syndrome were reviewed. 18 of them were male and 7 were female. Drop finger deformation were apparent in 25 cases and The supinator syndrome evoked embitterment test was positive for All patients. Operative neurolysis was done in 8 cases, conservation treatment 17 cases; 92 cadaver upper extremities were dissected for a study the relationship between supinator tunnel and posterior interosseous nerve.
Results:
22 cases had been followed up for an average of 9 months. 16 cases had a full recovery and 6 cases, a partial recovery. the anatomical study shows that The posterior interosseous nerve was compressed by Forhse arcade and the distal border of the supinator muscle during passive pronation forearm.
Conclusion:
The supinator syndrome evoked embitterment test was a new test for the diagnosis of supinator syndrome, it was found to be more sensitive and specific than the others test.
