Objectives/Interrogation: Axial loading of a wrist with deficient scapholunate ligament (SLL) induces scaphoid flexion and pronation, the radioscaphoid peak pressure displacing dorsoradially.

This study was designed to document the alignment of the scaphoid and the lunate under axial traction as opposed as what we know for axial compression.

Methods: The changes in the alignment of both, scaphoid and the tandem lunate-triquetrum, were assessed in 5 fresh normal cadaver wrists, axially loaded first and then axially tractioned, using an electromagnetic motion tracking device. The experiment was subsequently repeated after complete scapholunate ligament (SLL) sectioning and the results assessed using ANOVA with repeated measures. Significance was set at p<0.05.

Results and Conclusions:

Table 1 [Tab. 1]

Wrist traction substantially modifies the scaphoid misalignment typically found in the axially loaded SLL deficient wrists.

Consequently, it is mandatory to completely release the arthroscopic traction in three circumstances:

1.
when testing the scapholunate gap from the midcarpal joint,
2.
when checking the dorsoradial radioscaphoid impingement in the radiocarpal joint, and
3.
when fixing percutaneously the scaphoid flexion-pronation misalignement, to avoid an uncomplete scaphoid supination restoration.
