“…36 With increased contact, the radioscaphoid joint may have a role in inherent bony stability of the scaphoid after SLIL injury. 37 Differences in bony anatomy of the radius may influence rotational stability of the scaphoid after SLIL injury, which may explain why only some people progress to DISI deformities after SLIL injury. 36,37 Additional studies correlated lunate morphology with altered wrist kinetics.…”

“…The scapholunate (SL) interosseous ligament, secondary scaphoid ligamentous restraints, the flexor carpi radialis muscle, and joint conformity play interrelated roles in maintaining normal scapholunate alignment and carpal kinematics [12,16,17,20,23,26,28]. Dynamic SL interval instability represents an injury primarily to the SL ligament and may require stress x-ray imaging for diagnostic confirmation [12,19].…”

Background Multiple wrist x-ray images have been described to assess for scapholunate (SL) instability. Some views may be redundant. The purpose of this study was to compare three plain x-ray views in identifying a traumatic diastasis of the SL interval. Methods Nineteen patients (19 wrists) with a positive scaphoid shift test and surgically confirmed SL ligament damage were identified. There were 15 males and 4 females with a mean age of 39 years. Pre-operative x-rays were reviewed, including posteroanterior (PA) neutral and PA ulnar deviation views of the injured wrist, and PA clenched fist views of the injured and uninjured wrists. Dynamic SL instability was defined by an SL mid-interval gap of <3 mm and static SL instability by a gap of ≥3 mm in the PA neutral views. The mid-interval measurements were compared between x-ray images. Results There were 10 dynamic and 9 static SL instability cases. The PA ulnar deviation and the PA clenched fist views showed significantly greater SL gaps in comparison to the PA neutral views in dynamic but not static SL instability cases. In both categories of instability, there was no significant difference in the SL gaps between the two stress images. The PA clenched fist view of the uninjured wrist revealed SL gapping of >3 mm in 50% of patients but with generally greater gapping in the clenched fist view of the injured wrist. Conclusions The PA ulnar deviation and clenched fist stress views were equally effective in showing a dynamic SL diastasis following wrist injury. Neither view was more effective than a neutral PA view in diagnosing static SL instability.

Background Irreparable tears to the scapholunate (SL) interosseous ligament area are common causes of mechanical wrist pain and yet treatment of this condition remains challenging. The reduction association of the SL joint (RASL) technique alleviates pain while preserving wrist function by creating a fibrous pseudarthrosis stabilized by a cannulated screw placed through the SL joint. Although arthroscopic RASL (ARASL) is a minimally invasive alternative to the open procedure, its effectiveness in controlling pain and preserving wrist function has not been established. Questions/purposes To determinate whether ARASL was obtained relieve pain and restore function to the wrist. Patients and MethodsWe reviewed eight patients (nine wrists) who had ARASL for SL instability with a reducible SL ligament tear (chronic lesion) from 2005 to 2009. Seven of eight were males and mean age was 44.5 years (range, 38-56 years). We recorded pain using a scale, the Disabilities of the Arm, Shoulder and Hand (DASH) score, grip strength, and range of motion (ROM). Minimum followup was 12 months (mean, 34.6 months; range, 12-43 months). Results The visual analog pain score was rated 5.4 (range, 0-10) preoperatively and 1.5 (1-3) after ARASL. Postoperative grip strength of the wrist was 78% of the contralateral, unaffected wrist. The average postoperative wrist ROM was to 107°, 20% less than the preoperative ROM. The SL angle decreased from 70.5°to 59.3°. In three cases, screws were removed owing to loosening or symptoms. Conclusions Our preliminary observations suggest ARASL for treating irreparable SL ligament tear is feasible, controls pain, and improves wrist function while preserving ROM. Larger series with longer followup are required to confirm our observations.
