Introduction: Distal radial fractures are common and sometimes surgery is necessary. The volar locking plate has become the standard solution in the last years in many hospitals but the method is unproven scientifically. In this series we have retrospectively followed our early cases of volar plates.
Patients and Material: We identified all 68 patients (44 women and 9 men) at Lund University Hospital undergoing surgery using the TriMed® volar fixed-angle plate for distal radius fracture between January 2006 and December 2007. The mean age was 57 years (20–84). The patients were contacted by mail and sent a Quick-DASH, a validated outcome questionnaire. Eleven patients were excluded according to the protocol due to having another concomitant or bilateral fractures or other complicating conditions like stroke or hemiparesis or psychiatric disorder. 53 of the remaining 57 patients completed the Quick-DASH and plotted their subjective function, pain at rest and at activity as well as the cosmetic appearance on a 0–100 mm visual analogue scale (VAS). 50 patients came to the hospital for an additional radiogram and measurement of the range of motion (goniometer) and grip strength (JAMAR).
Results: Quick-DASH median was 4,5 (range 0–80), and mean 14. Seventeen (32%) of the patients had zero for VAS at rest. Ten (19%) had a DASH value of more than 30 implicating a less than satisfying result. Range of motion in de fractured wrists were 91% of the non-fractured and the grip strngth 82% of the contralateral.
Discussion: In the present study the patients regained near full function in their fractured wrists after the operation with the volar locking plate. The ROM of the fractured wrists was 91% of the ROM of the non-fractured wrists, whereas the grip strength of the fractured wrists was 82% compared to the contralateral side. These data are excellent and similar both to previous own results as well as other published studies.
The results of the Quick-DASH questionnaire, representing the subjective perception of the outcome, indicate that the patients are satisfied. Seventeen of the 53 patients scored zero on the DASH, suggesting a full recovery without any sequelae. In the population the median value is 2,5 (Abramo 2008). Ten of the patients had a DASH score over 30, indicating substantial subjective limitations in the daily life. Interestingly, there appears to be little or no correlation between high DASH scores and impaired ROM or grip strength. However, we noted that patients with high DASH scores also tended to score high in the VAS-question regarding subjective pain at activity. It was further noted that the patients with a DASH over 30 had a delay between injury and operation for a mean of 10,3 days (1–19 days) between injury and operation, compared to the patients with a DASH score below 30 who had a mean of 5,6 days (2–16 days) delay.
