Carpal canal pressures after volar plating of distal radius fractures.
Elevated pressures within the carpal canal are known to occur after distal radius fractures. Controversy exists regarding prophylactic carpal tunnel release after open reduction with internal fixation of distal radius fractures. The purpose of this study was to determine the tissue pressures within the carpal canal after volar plating of distal radius fractures. This study was a prospective, observational, IRB approved research study. Ten consecutive patients undergoing volar plating of distal radius fractures were enrolled. After the distal radius fractures were reduced and fixed with volar plates, slit catheters were inserted into the carpal canals for continuous postoperative pressure monitoring for 24 hours. The maximum recorded pressure was 65 mmHg, which occurred in the only patient with fracture blisters. Peak pressures remained at 40 mmHg or less (range 16-40, mean 29) in all patients without fracture blisters. At the conclusion of data collection, all pressures were at 31 mmHg or less. No patient complained of median nerve dysfunction during the study period. Routine prophylactic carpal tunnel release is not recommended after volar plating of distal radius fractures based on these pressure recordings.
