“…19 The SL gap for a strenous job was 4 mm static and 6 mm with stress, while for a nonstrenous job the SL gap was 2 mm static and 3 mm with stress. The mean Disabilities of the Arm, Shoulder, and Hand (DASH) score for a strenous job was 37 (range, , and for a nonstrenous job, 25 (range, [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. The Modified Mayo wrist score included 2 good, 10 fair, and 5 poor results.…”

“…The bone-ligamentbone (BLB) graft has been proven to be quite successful in knee ligament surgery, and various authors have studied this technique biomechanically to see whether it can be used to substitute for a nonreparable SL ligament. [23][24][25][26][27][28][29] Schuind 30 recommended use of a vascularized flap of the interosseous membrane. Weiss 31 described the transfer of a BLB graft harvested from the Lister tubercle.…”

This paper is a review of the various surgical techniques used in repair or reconstruction of the scapholunate ligament according to the clinical stages and anatomic-pathologic findings. Arthroscopy permits a direct evaluation of the scapholunate injury and the status of the articular surfaces. Specific indications for each type of scapholunate ligament tear are proposed, from the different types of dorsal capsulodesis to bone?ligament?bone techniques and tenodesis procedures. The authors' preferred techniques and literature review of the expected outcomes are presented.

“…Optimal treatment post-injury is still debated in the literature owing to the variety of available surgical repair techniques and grafting materials [7,8,11,19,20,[25][26][27][28][29][30][31][32][33][34][35]. Options include non-treatment accompanied by subsequent clinical evaluation of pain, function, and strength; scapholunate ligament mending using direct suture repair; autografts of bone-ligament-bone complexes obtained from other regions of the wrist; autografts of soft tissue to replace the scapholunate ligament obtained from other regions of the body; allografts of scapholunate ligament obtained from donors; scaphoid and lunate stabilization using Kirschner wires; and wrist capsulodesis.…”

The mechanical behaviour of human scapholunate ligaments is not well described in the literature with regard to torsion. In this study, intact scapholunate specimens were mechanically tested in torsion to determine whether a simultaneous tensile load was generated. Human intact scapholunate specimens (n = 19) were harvested. The scaphoid and lunate bones were potted in square chambers using epoxy cement, while the interposing ligament remained exposed. Each specimen was mounted rigidly in a specially designed test jig and remained at a fixed axial length during all tests. Specimens were subjected to a torsional load regime that included cyclic preconditioning, ramp-up, stress relaxation, ramp-down, rest, and torsion to failure. Torque and axial tension were monitored simultaneously. The relationship between torsion and tension was determined. Graphs of torque versus tension were generated, from which outcome measures were extracted. Tests demonstrated a clear relationship between applied torsion and the resulting generation of tension for the ligament during ramp-up (torsion-to-tension ratio, 38.86 +/- 29.00 mm; linearity coefficient R2 = 0.89 +/- 0.15; n = 19), stress relaxation (torsion-to-tension ratio, 23.43 +/- 15.84 mm; R2 = 0.90 +/- 0.09; n = 16), and failure tests (torsion-to-tension ratio, 38.81 +/- 26.39mm; R2 = 0.77 +/- 0.20; n = 16). No statistically significant differences were detected between the torsion-to-tension ratios (p = 0.13) or between the linearity (R2) of the best-fit lines (p > 0.085). A strongly coupled linear relationship between torsion and tension for the scapholunate ligament was exhibited in all test phases. This may suggest interplay between these two parameters in the stabilization of the ligament during normal motion and for injury cascades.

“…Relativ neuartig ist der Gedanke, das SL-Band bei chronischen Läsionen durch ein osteoligamentäres Transplantat in Anlehnung an die positiven Erfahrungen aus der Kreuzbandchirurgie wiederherzustellen. In ersten experimentellen Untersuchungen wurden Allografts von der Handwurzel [6] sowie osteoligamentäre Transplantate vom Fuû [9,14,18] und vom Tuberculum Listeri [17] auf ihre Eignung als SL-Bandersatz geprüft. Die erste klinische Arbeit zu diesem Thema publizierte Weiss [21].…”

Until now, the ideal treatment of scapholunate dissociation has not yet been found. Cuénod described an operation with reconstruction of the dorsal part of the scapholunate ligament using a bone-ligament-bone autograft (dorsal trapezoidometacarpal II ligament) and an additional dorsal capsulodesis using the dorsal intercarpal ligament. From December 2000 until January 2002, we operated on twelve patients with symptomatic chronic scapholunate dissociation without signs of osteoarthrosis using Cuénod's procedure. Preoperatively as well as at follow-up patients were evaluated using a traditional wrist score and a DASH-questionnaire in addition to clinical examination. X-rays of both wrists in two planes each and additional stress radiographs were done. All patients had an arthroscopy preoperatively and a CT scan before K-wire removal. The mean follow-up time was twelve months. Clinical follow-up showed good results (traditional wrist score: 77 points; DASH-score: 27 points), but with regard to the good preoperative findings (traditional wrist score: 73 points; DASH-score: 28 points) no significant improvement. Postoperative X-rays showed a correction of static instability in three cases; in four cases we found a recurrent SL gap, which was interpreted as failure of the transplanted ligament. Until now, one patient had to be reoperated by STT-fusion. In our patients, Cuénod's operation showed different results. So, further studies are necessary to find the correct indications for applying this procedure.
