Objective assessment of the alterations in wrist mobility with the fastrak(®) system following dorsal capsulodesis

The treatment for scapholunate dissociation is challenging and its management is varied depending on type, severity and duration of injury, and surgeon's preferred technique. This study aimed to objectively assess the variations in the range and patterns of wrist movements using the Fastrak(®) system in patients having undergone Blatt's dorsal capsulodesis (BDC). The wrist movements were successively measured between the operated and unoperated wrists, while the patients performed set tasks. Seventeen patients agreed to participate in the study. Following BDC the mean flexion loss was 23° (range 10°-38°). However, functional tasks revealed that the BDC did not adversely affect the function of the operated wrist. This novel study demonstrates objectively the functional restrictions that patients are likely to experience postoperatively following BDC. It would be interesting to note the pattern of wrist motion using the Fastrak(®) system in various other clinical settings.
