Purpose: Anatomical front and back (ANAFAB) reconstruction addresses the critical volar and dorsal ligaments associated with scapholunate dissociation. We hypothesized that patients with symptomatic, chronic, late-stage scapholunate dissociation would demonstrate improvements in all radiographic parameters and patient-reported outcomes (PROMs) after ANAFAB reconstruction., Methods: From 2018 to 2021, 21 ANAFAB reconstructions performed by a single surgeon were followed prospectively, with 20 patients having a minimum follow-up of 12 months. In total, 17 men and four women were included, with an average age of 49 years. Three patients had modified Garcia-Elias stage 3 disease, eight stage 4, seven stage 5, and three stage 7. ANAFAB reconstruction of intrinsic and extrinsic ligament stabilizers was performed using a hybrid synthetic tape/tendon graft in a transosseous reconstruction. Pre- and postoperative radiographic parameters, grip, pinch strength, the Patient-Rated Wrist Evaluation, PROMIS Upper Extremity Function, and PROMIS Pain Interference outcome measures were compared., Results: Mean follow-up was 17.9 months (range: 12-38). Radiographic parameters were improved at follow-up, including the following: scapholunate angle (mean 75.3° preoperatively to 69.2°), scapholunate gap (5.9-4.2 mm), dorsal scaphoid translation (1.2-0.2 mm), and radiolunate angle (13.5° to 1.8°). Mean Patient-Rated Wrist Evaluation scores for pain and function decreased from 40.6 before surgery to 10.4. We were unable to detect a significant difference in grip or pinch strength or radioscaphoid angle with the numbers tested. There were two minor complications, and two complications required re-operations, one patient who was converted to a proximal row carpectomy for failure of fixation, and one who required tenolysis/arthrolysis for arthrofibrosis., Conclusions: At 17.9-month average follow-up, radiographic and patient-reported outcome parameters improved after reconstruction of the critical dorsal and volar ligament stabilizers of the proximal carpal row with the ANAFAB technique., Type of Study/level of Evidence: Therapeutic IV., (Copyright © 2024 American Society for Surgery of the Hand.

Intervention for scapholunate instability is aimed at halting the degenerative process by restoring ligament integrity and normalizing carpal kinematics. Part 1 of this Current Concepts article reviewed the anatomy, kinematics, and biomechanical properties of the scapholunate ligament as well as its critical stabilizers. In this section, we provide a foundation for understanding the spectrum of scapholunate ligament instability and incorporate meaningful new anatomical insights that influence treatment considerations. These updates clarify the importance of the critical stabilizers of the scapholunate interval, ligament-specific considerations in scapholunate ligament reconstruction, and the risks of ligament disinsertion when surgically exposing the dorsal wrist. We propose a ligament-based treatment algorithm based on the stage of injury, degree and nature of ligament damage, and presence of arthritic changes., (Copyright © 2023 American Society for Surgery of the Hand.

Injuries to the scapholunate joint are the most frequent cause of carpal instability. The sequelae of these injuries account for considerable morbidity, and if left untreated, may lead to scapholunate advanced collapse and progressive deterioration of the carpus. Rupture of the scapholunate interosseous ligament and its critical stabilizers causes dyssynchronous motion between the scaphoid and lunate. Additional ligament injury or attenuation leads to rotary subluxation of the scaphoid and increased scapholunate gap. Intervention for scapholunate instability is aimed at halting the degenerative process by restoring ligament integrity and normalizing carpal kinematics. In the first section of this review, we discuss the anatomy, kinematics, and biomechanical properties of the scapholunate ligament as well as its critical ligament stabilizers. We provide a foundation for understanding the spectrum of scapholunate ligament instability and incorporate meaningful new anatomical insights that influence treatment considerations. The purpose is to provide an update regarding the anatomy of the scapholunate ligament complex, importance of the critical ligament stabilizers of the proximal carpal row, introduction of safe technique to surgically expose the scaphoid and lunate, as well as pathoanatomy as it pertains to the treatment of scapholunate dissociation. In the second section of this review, we propose a novel ligament-based treatment algorithm based on the stage of injury, degree and nature of ligament damage, and presence of arthritic changes., (Copyright © 2023.

Purpose: If early active motion after 3-ligament tenodesis is safe, it may yield more patient comfort and an early return to activities. Therefore, the aim of this study was to investigate whether early active motion is noninferior to late active motion after 3-ligament tenodesis for scapholunate interosseous ligament injuries., Methods: This prospective, multicenter cohort study, using a noninferiority design with propensity score matching, compared a late active motion protocol (immobilization for 10-16 days, wrist therapy in weeks 5-6) with an early active motion protocol (immobilization for 3-5 days, wrist therapy during week 2). Patients who were older than 18 years, had complete baseline information on demographics, and underwent 3-ligament tenodesis were included. The outcome measures were postoperative Patient-Reported Wrist/Hand Evaluation scores, pain, complications, return to work, range of motion, grip strength, and satisfaction with treatment results at 3 months of follow-up., Results: After propensity matching, a total of 108 patients were included. Patient-Reported Wrist/Hand Evaluation and pain scores during physical load following an early active motion protocol were noninferior compared with scores following a late active motion protocol. Furthermore, early active motion did not lead to an increase of complications, differences in range of motion or grip strength, or less satisfaction with the treatment result. An earlier return to work was not observed., Conclusions: Early active motion leads to noninferior results without more complications as compared with late active motion. Based on these findings, early active motion can be considered safe, and might be recommended due to its potential benefits compared with late active motion after 3-ligament tenodesis., Type of Study/level of Evidence: Therapeutic III., (Copyright © 2022.

Purpose: This study compared the interobserver agreement of arthroscopic classification of suspected scapholunate interosseous ligament (SLIL) pathology with and without midcarpal arthroscopy to help inform diagnostic strategies. It also measured the association of midcarpal arthroscopy with recommendations for reconstructive surgery. The association of midcarpal arthroscopy with the type of surgery recommended was also studied., Methods: Fourteen consecutive videos of diagnostic radiocarpal and midcarpal wrist arthroscopy for suspected SLIL pathology were selected. An international survey-based experiment was conducted among upper extremity surgeons of the Science of Variation Group. Participants were randomized to view either radiocarpal arthroscopic videos or radiocarpal and midcarpal videos. Surgeons rated SLIL pathology according to the Geissler classification and recommended surgical or nonsurgical treatment. If surgical treatment was recommended, they indicated the type of procedure., Results: The interobserver agreement for the Geissler classification was slight/fair for observers who reviewed midcarpal and radiocarpal videos and for those who viewed radiocarpal videos only. Viewing midcarpal videos was associated with higher pathology grades, the recommendation for reconstructive surgery, and a preference for tenodesis over scapholunate ligament repair., Conclusions: Diagnostic wrist arthroscopy for a wrist with normal radiological alignment has poor interobserver agreement., Clinical Relevance: The pursuit of a pathology that accounts for wrist symptoms in a nonspecific interview and examination and normal radiographs is understandable; however, the low reliability of the scapholunate pathology of diagnostic arthroscopy might be associated with more potential harm than benefit., (Copyright © 2022.

Conventional X-ray imaging is usually the first diagnostic assessment after clinical examination in case of suspected scapholunate interosseous ligament (SLIL) injury. Nevertheless, there is no consensus on the norms of the scapholunate distance (SLD) or carpal angles. Therefore, we aimed to determine the utility of static and dynamic radiographs in the diagnostic of an SLIL injury in comparison with the reference standard arthroscopy. We retrospectively analyzed the preoperative X-ray series and surgical records of arthroscopies of 414 patients. Radiological assessment included conventional static X-rays in the posteroanterior (PA) projection, clenched fist views in ulnar and radial deviations, in which the SLD at the midportion of the scapholunate (SL) joint was measured. The scapholunate angle (SLA) and radiolunate angle (RLA) were measured on lateral wrist radiographs. Receiver operating characteristic (ROC) curves were created to determine possible cut-off points of the radiological indices for the diagnosis of SLIL injury. Further, a logistic regression with the parameters having the highest area under the curve (AUC) was calculated. We found that SLD in ulnar inclination (AUC= 0.774), SLD in PA projection (AUC = 0.748), and SLA (AUC = 0.737) had the highest diagnostic value. The AUC of the combination of these three parameters was 0.822 for all patients with any SLIL lesion and 0.850 for patients with SLIL lesions of 3-4 Geissler grade. Further investigation of SLIL pathology would be appropriate in the case of SLD in ulnar inclination of 2.7 mm, SLD in PA projection of 1.9 mm and SLA of 63°., Competing Interests: Conflict of interest The authors have no conflicts of interest to declare., (Copyright © 2022 Elsevier Ltd.

Purpose: To compare the kinematic effects of the dorsal fiber-splitting approach for scapholunate ligament repair to a dorsal "window" approach that spares all ligaments., Methods: We randomized 24 fresh-frozen paired cadaveric forearms to either the dorsal fiber-splitting capsulotomy approach (FSC) or the dorsal window approach (window) following scapholunate interosseous ligament (SLIL) division. Loaded fluoroscopic radiographs were obtained after each of the 4 testing conditions following cyclic loading (200 cycles; 71 N): (1) intact SLIL, (2) SLIL-division, (3) surgical approach, and (4) closure. FSC specimens were randomly allocated to 2 subgroups for closure with either a suture anchor (n = 6) or a simple running suture closure (n = 6). Radiographic parameter measurements included the scapholunate gap, radiolunate angle, scapholunate angle, and dorsal scaphoid translation., Results: Following the FSC, there were significant alterations in all radiographic parameters when compared with the intact and SLIL-division conditions. The window approach did not result in significant changes in any radiographic parameter. When compared to the window approach, all radiographic parameters of the FSC approach were significantly altered. Following closure with suture anchors in the FSC group, radiographic parameters improved, whereas with standard closure they failed to do so. Despite anchor closure, dorsal scaphoid translation, radiolunate angle, and scapholunate angle all remained elevated compared with scapholunate-divided wrists., Conclusions: The FSC produced significant changes in carpal posture under load, including scapholunate diastasis, dorsal intercalated segment instability, and dorsal scaphoid translation in SLIL-deficient wrists. The window approach preserved the critical dorsal ligament stabilizers and did not produce changes in carpal posture., Clinical Relevance: The FSC may create iatrogenic changes in carpal posture that cannot be fully corrected with standard or anchor closure. The window approach does not alter carpal posture and should be considered when performing surgical procedures on the scaphoid or lunate., (Copyright © 2021 American Society for Surgery of the Hand.

Purpose: Scapholunate (SL) ligament tears in the acute setting can be treated by primary repair through various techniques. The purpose of this study was to compare repair of the SL ligament with suture anchors alone versus repair of the SL ligament augmented with suture tape., Methods: Twelve fresh-frozen cadavers (6 matched pairs) underwent a dorsal approach to the wrist and the SL ligament was sharply dissected off of its scaphoid attachment. Six cadavers underwent direct repair of the SL ligament using 2 suture anchors. The other 6 underwent repair of the SL ligament, which was then augmented with suture tape. All specimens then underwent load to failure testing using tensile distraction forces applied by a universal testing system. Maximum load to failure and mode of failure were recorded., Results: Maximum load to failure (135 N; SD, 44.94 N) for specimens that were repaired and augmented with the internal brace was higher than that for specimens in the repair-only group (68 N; SD, 14.69 N)., Conclusions: Biomechanical testing demonstrated a higher maximum load to failure in SL ligament repairs augmented with suture tape compared with a repair-only technique in this cadaveric model., Clinical Relevance: Acute SL ligament injuries may benefit from suture tape augmentation by increasing the stability of the primary repair. This may prove to be beneficial in higher-demand patients., (Copyright © 2021 American Society for Surgery of the Hand. Published by Elsevier Inc. All rights reserved.)

Purpose: To assess the validity and reliability of the posterior radioscaphoid angle (PRSA), an indicator of dorsal displacement of the scaphoid, in distinguishing wrists with and without chronic scapholunate instability (SLI)., Methods: We prospectively evaluated 40 patients (22 men and 18 women; mean age, 46 ± 13 years) with suspected SLI with radiographs and computed tomography arthrography. Based on these data, 3 groups were defined: positive SLI (n = 16), negative SLI (n = 19), and questionable SLI (n = 5). An independent reader measured the PRSA on sagittal computed tomography images using the same procedure., Results: The PRSA median values were significantly lower in the negative SLI group (98°) compared with the positive SLI (110°) and questionable SLI (111°) groups. The difference between the positive SLI and questionable SLI groups was not significant. The best differentiation between patients with and without SLI was obtained with a PRSA threshold value of 103° (specificity of 86% and sensitivity of 79%)., Conclusions: In this preliminary study, PRSA analysis offers a quantitative tool for the evaluation of dorsal scaphoid displacement in cases of SLI, including for patients presenting with questionable initial radiography findings., Type of Study/level of Evidence: Diagnostic II., (Copyright © 2021 American Society for Surgery of the Hand.

The treatment of athletes with carpal ligament injuries provides many challenges. Our initial goals remain to make a timely and accurate diagnosis, provide treatment options, and create an environment for shared decision making. To optimize outcomes and facilitate return to play, early surgical intervention may be warranted.

Purpose: Current biomechanical data suggest that static scapholunate (SL) ligament dissociation occurs only when there is loss of competence of the extrinsic ligaments either acutely or with attenuation over time. We aimed to identify whether patients with an SL gap greater than 2 mm demonstrated concomitant dorsal radiocarpal ligament (DRC) and dorsal intercarpal ligament (DIC) ligament changes on magnetic resonance imaging (MRI) scans that were identified as having an SL ligament tear., Methods: We included 90 patients who had a posttraumatic MRI scan of the wrist diagnosed with an SL injury. We recorded basic demographics; 2 attending fellowship-trained musculoskeletal radiologists evaluated the integrity of the SL, DRC, and DIC ligaments and graded these as normal, low-grade injury (sprain or partial tear) or full-thickness tear. The association between the integrity of the DRC and DIC ligaments and the presence of a scapholunate gap of 2 mm or greater was analyzed., Results: A total of 48 patients (53%) had an SL distance of 2 mm or greater on MRI. Of these patients, 28 (58%) had a partial or total tear of the DIC and/or DRC ligament. Compared with patients with an SL interval less than 2 mm, patients with an SL interval 2 mm or greater more often demonstrated DIC signal change (31% vs 12%), DRC signal change (52% vs 14%), or combined or isolated DIC and/or DRC signal change (52% vs 14%)., Conclusions: Dorsal extrinsic ligaments demonstrate MRI signal change suggestive of acute or chronic injury in patients with an SL interval 2 mm or greater more often than in patients with an SL interval less than 2 mm. These results reinforce that MRI findings of SL ligament tear need to be interpreted in a larger context, perhaps with additional attention to the DIC and DRC appearance upon MRI. In addition, MRI evaluation of dorsal extrinsic ligaments may aid in clinical decision-making for patients with SL injury., Type of Study/level of Evidence: Diagnostic IV., (Copyright © 2019 American Society for Surgery of the Hand.

Injuries to the hands and wrist are common in athletes. Injuries include acute fractures, dislocations, ligamentous, and tendon injuries, as well as more chronic injuries such as sprains and strains. Complications in the treatment of sports injuries of the hand and wrist may be divided into 2 categories: incorrect or delayed diagnosis and iatrogenic injury related to treatment. This article highlights common sports injuries of the hand and wrist and their complications, and includes tips for successful management., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Purpose: To evaluate the diagnostic utility of scaphoid dorsal subluxation on magnetic resonance imaging (MRI) as a predictor of scapholunate interosseous ligament (SLIL) tears and compare this with radiographic findings., Methods: Thirty-six MRIs were retrospectively reviewed: 18 with known operative findings of complete Geissler IV SLIL tears that were surgically repaired, and 18 MRIs performed for ulnar-sided wrist pain but no SLIL tear. Dorsal subluxation of the scaphoid was measured on the sagittal MRI cut, which demonstrated the maximum subluxation. Independent samples t tests were used to compare radiographic measurements of scapholunate (SL) gap, SL angle, and capitolunate/third metacarpal-lunate angles between the SLIL tear and the control groups and to compare radiographic measurements between wrists that had dorsal subluxation of the scaphoid and wrists that did not have dorsal subluxation. Interrater reliability of subluxation measurements on lateral radiographs and on MRI were calculated using kappa coefficients., Results: Thirteen of 18 wrists with complete SLIL tears had greater than 10% dorsal subluxation of the scaphoid relative to the scaphoid facet. Average subluxation in this group was 34%. Four of 18 wrists with known SLIL tears had no subluxation. No wrists without SLIL tears (control group) had dorsal subluxation. The SL angle, capitolunate/third metacarpal-lunate angle and SL gap were greater in wrists that had dorsal subluxation of the scaphoid on MRI. Interrater reliability of measurements of dorsal subluxation of the scaphoid was superior on MRI than on lateral x-ray., Conclusions: An MRI demonstration of dorsal subluxation of the scaphoid, of as little as 10%, as a predictor of SLIL tear had a sensitivity of 72% and a specificity of 100%. The high positive predictive value indicates that the presence of dorsal subluxation accurately predicts SLIL tear., Type of Study/level of Evidence: Diagnostic II., (Copyright © 2017 American Society for Surgery of the Hand.

Purpose: To assess midterm outcomes of our bone-ligament-bone (BLB) grafts for chronic scapholunate (SL) instability and better define criteria for their use., Methods: We conducted a retrospective review of 26 patients treated with BLB grafts and dorsal capsulodesis between 1997 and 2009. Twenty-four patients were reviewed. Mean follow-up was 8.2 years. Two patients had dynamic lesions, 7 had SL dissociation, 14 had a dorsal intercalated segment instability lesion, and 1 had SL advanced collapse stage 1. Mean age at surgery was 46 years. All patients presented with pain and 14 had lack of strength. Results were reviewed clinically and radiologically. Images were assessed by 4 surgeons and 1 radiologist for radial styloid, radioscaphoid, radiolunate, midcarpal, and scaphotrapeziotrapezoid degenerative changes., Results: Five patients needed subsequent 4-corner arthrodesis. Of the remaining 19 patients at follow-up, both extension and flexion decreased to 73% of the contralateral side. Postoperative grip strength improved from 78% to 90% of the nonsurgical wrist. Quick Disabilities of the Arm, Shoulder, and Hand score was 10 of 100 and the Patient-Rated Wrist Evaluation score was 10 of 100. Radiologically, the SL gap was improved and maintained at follow-up. The SL angle (mean before surgery, 79°) was initially corrected to 69° but returned to preoperative values at follow-up. Eleven of the 19 cases had signs of midcarpal arthritis., Conclusions: Bone-ligament-bone grafts with SL dorsal capsulodesis were able to restore and maintain an improved SL interval in all patients. The technique achieved good clinical results and high patient satisfaction, but it did not stop the progression of arthritis, particularly at the midcarpal level. This technique is an option for isolated unrepairable lesion of the dorsal SL ligament with an easily correctable lunate and especially when restoration of grip strength is important., Type of Study/level of Evidence: Therapeutic IV., (Copyright © 2015 American Society for Surgery of the Hand.

Purpose: To evaluate the biomechanical properties of 3 scapholunate repair techniques., Methods: In 51 cadavers, the scapholunate ligament was exposed through a dorsal approach, incised at its scaphoid insertion, and repaired using 1 of 3 techniques: 2 single-loaded suture anchors, 2 double-loaded suture anchors, or 2 transosseous sutures. Twenty-four repaired specimens underwent load to failure (LTF) testing using tensile distraction on a servo-hydraulic machine. Twenty-seven specimens underwent cyclical testing to measure gap formation at the scapholunate joint., Results: The mode of failure was suture pullout through the substance of the ligament in 22 specimens, failure at the bone suture interface in 1, and anchor pullout in 1. Double-loaded anchor repairs demonstrated a significantly higher mean ultimate LTF compared with single-loaded anchor (91 N vs 35 N) and transosseous (91 N vs 60 N) repairs. Transosseous repairs demonstrated a higher mean ultimate LTF compared with single-loaded suture repairs (60 N vs 35 N). After 300 cycles, the average gap for the transosseous repair group was double that for the single- and double-loaded repairs, although not statistically significant., Conclusions: Primary scapholunate ligament repairs using double-loaded suture anchors demonstrated significantly higher strength compared with single-loaded anchors and transosseous repairs. On cyclic loading, transosseous repairs demonstrated the greatest gap formation with no measurable difference between single- and double-loaded repairs., Clinical Relevance: In a cadaveric model for primary repairs, double-loaded suture anchors demonstrated the highest LTF and offer a similar but unproven performance in vivo., (Copyright © 2015 American Society for Surgery of the Hand.

Purpose: To evaluate the natural history of untreated complete or partial scapholunate (SL) ligament tears associated with displaced distal radius fractures., Methods: Between 1995 and 1997, 51 consecutive patients aged < 60 years with displaced distal radius fractures were examined arthroscopically to assess for concomitant soft tissue injuries. Thirty-two of 51 patients had an SL ligament tear, 10 had a complete tear (Lindau grade 3), and 22 had a partial tear (Lindau grades 1 and 2). Thirty-two patients had AO type-C fractures, 3 had type-B fractures, and 16 had type-A fractures. In 2010, 47 of the 51 patients were still alive, and they were invited for an interview, clinical examination, and radiography., Results: Thirty-eight of the 51 original patients participated in the long-term follow-up. Mean grip strength was 83% relative to the contralateral hand in patients with a complete tear, as compared with 92% in patients with partial or no SL tears (nonsignificant). Median Disabilities of the Arm, Shoulder, and Hand questionnaire score was 2 (range, 0‒55) for complete SL tears, compared with 9 (range, 0‒70) for the others (nonsignificant). No differences were found regarding visual analog scale pain or wrist motion/forearm rotation. None of the patients developed a static SL dissociation or a SL advanced collapse wrist., Conclusions: No major differences were found in the subjective, objective, or radiographic outcome after a complete (grade 3) or partial (grade 1 or 2) SL untreated tear associated with displaced distal radius fracture. It should be noted that none of the patients had a grade 4 SL tear, which may have a different outcome., Type of Study/level of Evidence: Prognostic II., (Copyright © 2015 American Society for Surgery of the Hand.

Purpose: To evaluate the intraobserver and interobserver variability in diagnosing scapholunate dissociation (SLD) by wrist cineradiography., Methods: A musculoskeletal radiologist, hand surgeon, and trauma surgeon assessed the records of 50 consecutive wrist cineradiographies performed in 25 patients. Fluoroscopy was performed on the unaffected and affected wrist and consisted of radiographer-controlled passive flexion-extension and passive radial-ulnar deviation in both posteroanterior and lateral projections. To determine the intraobserver variability, the 3 reviewers reassessed all wrist cineradiographies 6 months after their first assessment. The kappa coefficient for interobserver agreement was calculated using the jackknife method. The Cohen kappa was used to assess intraobserver variability., Results: The interobserver variability for diagnosing SLD by cineradiography was excellent (κ = 0.84). The intraobserver variability for the hand surgeon was excellent (κ = 0.80), and was good for the radiologist (κ = 0.72) and the trauma surgeon (κ = 0.76)., Conclusions: Cineradiography is a promising and helpful, noninvasive tool for diagnosing SLD. It is widely available and has relatively low costs. Conventional radiographs remain essential in the primary workup for suspected SLD. However, we recommend cineradiography when an SLD is clinically suspected., Type of Study/level of Evidence: Diagnostic III., (Copyright © 2014 American Society for Surgery of the Hand.

Classical arthroscopic techniques for scapholunate instability consist of debridement, thermal shrinkage, and percutaneous pinning. Good results are obtained in acute lesions or in chronic partial tears, but they are less predictable when the lesion is complete, because of the poor healing capacity of the scapholunate ligament and because it is not possible to perform an anatomic ligamentous reconstruction with these techniques. Open techniques are thus required for reconstruction, but they damage the soft tissues. We recently published a description and cadaver study of an arthroscopic ligamentoplasty, trying to combine the advantages of arthroscopic techniques (minimally invasive surgery) and open techniques (reconstruction of the ligament). With this approach, it is possible to reconstruct the dorsal scapholunate ligament and the secondary stabilizers while causing minimal damage to the soft tissues and avoiding injury to the posterior interosseous nerve and detachment of the dorsal intercarpal ligament. The current report describes an additional step to this technique with which it is possible to reconstruct the volar portion of the scapholunate ligament. We also describe an early mobilization postoperative protocol that we believe is equally important., (Copyright © 2013 American Society for Surgery of the Hand. Published by Elsevier Inc.
