“…However, the results of these reconstructions are unpredictable, and there is no single effective surgical procedure. [6][7][8][9][10][11][12][13][17][18][19] Although many studies have reported that the use of suture anchors improves functionality, the scapholunate distance often undergoes widening. Additionally, one of the reasons many reconstruction procedures have failed is the stretching of the tendon graft and weak fixation.…”

“…However, the results are highly variable, ranging from satisfactory to generalized failures. 13,18,19 Recently, a novel surgical technique using an internal brace (IB) has been introduced for SLL. The IB technique is a reinforcement method that uses high-strength nonabsorbable tape to provide immediate enhanced strength and support during critical periods of ligament healing.…”

Introduction The scapholunate ligament is the most important stabilizer of the scapholunate articulation. The management of chronic irreversible injuries of this ligament in the absence of preexisting arthritis of the wrist joint remains controversial. Recently, surgeons introduced a novel surgical technique using an internal brace (IB). Several biomechanical studies on this technique have been conducted using cadavers; however, very few studies have discussed the results in detail in actual clinical practice. Therefore, herein, we investigated the radiological and functional results of patients who underwent IB augmentation as a treatment for chronic scapholunate dissociation. Methods This retrospective study was conducted from April 2018 to May 2022. Twenty-two patients with chronic scapholunate dissociation were treated using the IB augmentation technique, of whom 17 were followed-up for at least 1 year. Radiological results, including scapholunate distance, scapholunate angle, and radioscaphoid angle, were collected. Furthermore, clinical parameters, such as the visual analog scale (preoperative and at final follow-up), the Disabilities of the Arm, Shoulder, and Hand scores (preoperatively and at 3, 6, and 12 months postoperatively), and Mayo wrist scores (preoperative and at final follow-up), were measured. Results The scapholunate distance increased significantly in the affected wrist compared to the unaffected wrist, which improved after reconstruction in all wrist positions (P < 0.05). Compared to the unaffected wrist, the scapholunate angle increased significantly in all positions (P < 0.05) except for extension (P = 0.535) and improved after reconstruction in all wrist positions. The radioscaphoid angle significantly increased compared to the angle of the unaffected wrist in all positions (P < 0.05) except for extension (P = 0.602) and clenched fist (P = 0.556). This angle improved after reconstruction in all wrist positions except for extension (P = 0.900). The visual analog scale score (7–2, preoperatively and at final follow-up) and Mayo wrist score (53–82, preoperatively and at final follow-up) improved after surgery. The Disabilities of the Arm, Shoulder, and Hand scores also improved after surgery (68, 53, 30, 7, preoperatively and at 3, 6, and 12 months postoperatively). Conclusions This study revealed that scapholunate ligament reconstruction using an autologous tendon and suture tape is a good reconstruction technique that can improve clinical symptoms and radiographic parameters with a shorter operation time and fewer complications than other reconstruction methods.

“…19 Kang et al conducted load-to-failure tests between dorsal SLIL repair methods and Kakar and Greene conducted load-to-failure tests between 360 SLIL reconstruction with only tendon and 360 SLIL reconstruction with tendon and internal brace. 21,27 But there's no biomechanical study between Dorsal SLIL reconstrudction method and 360 SLIL reconstruction. So we conducted a biomechanical comparative study between MBT and MHT to emphasize the volar SLIL.…”

Purpose: This study compares the kinematic changes after the procedures for scapholunate interosseous ligament (SLIL) reconstruction—the modified Brunelli technique (MBT) and Mark Henry’s technique (MHT). Methods: Ten cadaveric wrists were used. The scapholunate (SL) interval and angle and radiolunate (RL) angle were recorded using the MicroScribe system. The SL interval was measured by dividing the volar and dorsal portions. Four motions of the wrist were performed—neutral, flexion, extension, and clenched fist (CF) positions—and compared among five conditions: (1) intact wrist, (2) volar SLIL resection, (3) whole SLIL resection, (4) MBT reconstruction, and (5) MHT reconstruction. Results: Under the whole SLIL resection condition, the dorsal SL intervals were widened in all positions. In all positions, the dorsal SL intervals were restored after MBT and MHT. The volar SL interval widened in the extension position after volar SLIL resection. The volar SL interval was not restored in the extension position after MBT and MHT. The SL angle increased in the neutral and CF positions under the whole SLIL resection condition. The SL angle was not restored in the neutral and CF positions after MBT and MHT. The RL angle increased in the neutral and CF positions under the whole SLIL resection condition. The RL angle was not restored in the neutral and CF positions after MBT and MHT. Conclusion: The MBT and MHT may restore the dorsal SL interval. No significant differences in restoration of the SL interval between MBT and MHT were found in the cadaveric models. Clinical relevance: No significant differences between MBT and MHT were found in the cadaveric models for SLIL reconstruction. When considering the complications due to volar incision and additional procedures in MHT, MBT may be a more efficient technique in terms of operative time and injury of the anterior structures during surgery, but further research is needed.
