Table 1.
Baseline of characteristics of patients.
Figure 1.
The figure displays the records of VAS levels at different time points.
The VAS scores in both surgical groups showed notable decline with the time course while no changes occurred in control group during the follow-up. The overall postoperative VAS levels of focal pain group were much lower than that of diffuse pain group (P<0.01).
Figure 2.
Graphs illustrate results of two-point discrimination and BPI-DPN in all groups.
A, B, both surgical groups show marked decline in plantar big toe and small toe 2-PD while no apparent improvement can be observed in the control group; C, both surgical groups exhibit significant alleviation in pain severity through surgery while the control group remained at nearly the same level of mean severity of pain; D, decrease in the mean activity interference was displayed in both surgical groups and almost no changes existed in the control group.

Figure 3.
Longitudinal sonograms showing difference of morphological changes after surgical decompression between two patients with focal and diffuse painful DPN.
A and B represent the preoperative (Da: 4.4 mm, Dt: 7.6 mm) and postoperative (Da: 2.9 mm, Dt: 6.3 mm) sonograms of the common peroneal nerve at the level of knee joint of patient with focal painful DPN. C and D represent the preoperative (Da: 4.2 mm, Dt: 7.0 mm) and postoperative (Da: 3.7 mm, Dt: 6.8 mm) sonograms of the common peroneal nerve at the level of knee joint of patient with diffuse painful DPN.
