Arthroscopic management of scapholunate complex injuries associated with distal radius fractures. J Orthop 2024; 51:73-80. [PMID: 38333048 PMCID: PMC10847947 DOI: 10.1016/j.jor.2024.01.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Accepted: 01/18/2024] [Indexed: 02/10/2024] Open
Abstract
Scapholunate complex injuries are the most frequent lesions associated with distal radius fractures and the treatment algorithm according to the stage of the instability remains controversial. However, there is an admitted consensus around the necessary treatment of the associated high-grade instabilities. They occur frequently in young patients after high energy trauma, and not treated, they can lead to chronic wrist pain and eventually to scapholunate advanced collapse. The routine use of the arthroscopy provides an accurate intraoperative staging of the lesions and allows a tailored treatment depending on the severity of the scapholunate instability.

Open Volar STT Ligament Reconstruction to Augment the Mathoulin's Arthroscopic Dorsal Capsuloligamentous Reconstruction: Technique Description and Case Reports. J Wrist Surg 2024; 13:66-74. [PMID: 38264128 PMCID: PMC10803145 DOI: 10.1055/s-0043-1768931] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Accepted: 04/13/2023] [Indexed: 01/25/2024]
Abstract
Background The results of Mathoulin's arthroscopic dorsal capsuloligamentous reconstruction (ADCLR) are excellent in many patients with scapholunate instability, though less consistently good in higher grade instabilities. The purpose of this article is to describe a novel technique of volar scaphotrapeziotrapezoid (STT) reconstruction which may be used to augment rotational control of the scaphoid, in conjunction with the ADCLR, for use in European Wrist Arthroscopy Society (EWAS) grade IV/V instabilities. Description of Technique Following completion of ADCLR, the STT joint is approached through the flexor carpi radialis sheath. The palmaris longus tendon is harvested. Fluoroscopy is used to site guide wires for tunnel placement in the distal scaphoid and the proximal trapezium; 3.5-mm tunnels are overdrilled in both bones, to a depth of 8 mm. The palmaris graft is then anchored in the scaphoid tunnel with a mini-DX SwiveLock anchor. The graft is tensioned, then anchored in the trapezium tunnel with another anchor. Patients and Methods We retrospectively selected two young men heavy manual workers who had this procedure more than 12 months previously for scapholunate instability, with static radiographic abnormalities and a drive through sign (EWAS grade V). The patients were reviewed after 12 months, for assessment of visual analog scale, quick disabilities of the arm, shoulder, and hand, and patient-rated wrist/hand evaluation scores, range of motion, and grip strength. Results Both patients had marked improvements of wrist comfort and function at 1 year, and were able to return to their normal duties at work and complete all activities of daily living with minimal symptoms. Conclusion This volar STT reconstruction may expand the success of the Mathoulin's ADCLR into higher grade instabilities.

Correlation between dorsal capsulo-scapholunate septum (DCSS) lesion and predynamic scapholunate instability. HAND SURGERY & REHABILITATION 2024; 43:101609. [PMID: 37879459 DOI: 10.1016/j.hansur.2023.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 10/05/2023] [Accepted: 10/09/2023] [Indexed: 10/27/2023]
Abstract
OBJECTIVE Scapholunate instability is the most common ligament injury of the wrist. In case of predynamic instability, diagnosis can be difficult, even under arthroscopy. Scapholunate instability is not the result of an isolated injury to the scapholunate interosseous ligament. Scapholunate stability is dependent not only on the scapholunate ligament, but on a complex that is comprising intrinsic and extrinsic ligaments. The dorsal capsule-scapholunate septum (DCSS) is one of the secondary stabilizers of the scapholunate complex. The objective of the present study was to investigate the correlation between DCSS lesion and predynamic scapholunate instability. METHOD A prospective multicenter study included patients who underwent wrist arthroscopy for traumatic wrist. Arthroscopic DCSS lesion stage and instability according to European Wrist Arthroscopy Society stage were assessed. RESULTS Twenty-seven subjects were included. We found a significant correlation between pathological DCSS and predynamic scapholunate instability and a correlation between DCSS lesion severity and instability level. CONCLUSION Isolated DCSS lesion should be considered a predictive factor for predynamic instability.

Radiologic Evolution after Scapholunate Dorsal Capsulodesis for Chronic Tears. J Wrist Surg 2023; 12:433-438. [PMID: 37841361 PMCID: PMC10569849 DOI: 10.1055/s-0043-1764159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Accepted: 01/24/2023] [Indexed: 10/17/2023]
Abstract
Background Many debates are still ongoing for the management of chronic scapholunate (SL) injuries. We have proposed an arthroscopic technique of dorsal capsulodesis with good clinical results. We now propose a radiological follow-up. Purpose To determine if arthroscopic dorsal capsulodesis can improve the radiographic SL angle and maintain this correction over time. Methods From January 2020 to January 2021, we included every patient with an SL instability and sorted them according to the European Wrist Arthroscopy Society (EWAS) classification. All patients had bilateral X-rays with a measurement of the radiolunate (RL) and SL angles for both the pathologic and healthy side. We also included patients with lunotriquetral or triangular fibrocartilage complex lesions. The exclusion criteria were the presence of arthritis and persistent intraoperative SL instability after capsulodesis. An arthroscopic dorsal capsulodesis was performed in all patients as originally described by Mathoulin. The RL and SL angles were then again measured on the immediate postoperative X-ray, and then again at 3, 6, and 12 months postoperatively. The statistical analysis was done using a paired Student's t -test with 145 degrees of freedom and α = 0.05. Results We included a total of 146 patients with a 1-year follow-up. Both the RL angle and the SL angles approach the healthy side at 12 months postoperatively. The RL angle has increased from -7.23 degrees to 4.37 degrees; the difference is still statistically significative, but it is almost equal to the healthy side (5.16 degrees). The SL angle has lowered from 74.55 to 54.95; the difference is still statistically and radiologically significative (6.788 degrees) but has been lowered by 74.3%. Conclusion This study shows that this technique can normalize the dorsal intercalated segment instability (DISI) over time without the need for any pinning or invasive ligament reconstructive surgery. Level of Evidence Level IV, cohort study. Clinical Relevance Dorsal capsulodesis should be considered in all reducible SL injuries, even when DISI is present.

Abstract
Purpose We have previously described arthroscopic-assisted volar scapholunate (SL) capsulodesis as an alternative technique for addressing volar SL interosseous ligament (SLIL) injuries. In this article, we report the outcomes of this procedure in a cohort of patients. Methods Postoperative outcomes including range of motion, grip strength, visual analog scale (VAS) pain score, Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Mayo Wrist Score were assessed through a prospective review of six patients in a single center who underwent this procedure. Results Six patients (four male and two female) with a mean age of 43 ± 14 years were evaluated in the study. The mean duration of follow-up was 41 ± 17 weeks. Postoperative outcomes noted a reduction in VAS pain score from 8 before surgery to 0.7 postoperatively ( p = 0.00004) and improvement in Mayo Wrist Score (42 preoperatively to 80 postoperatively; p = 0.001), grip strength (86% of contralateral side; p = 0.20), and flexion arc (81% of contralateral side; p = 0.08). QuickDASH was 20 ± 8 and Patient-Rated Wrist Evaluation score was 13 ± 2 at the last clinical follow-up. There was an improvement in SL gap ( p = 0.03), SL angle ( p = 0.11), and radiolunate angle ( p = 0.15) measurements postoperatively. Conclusions The described arthroscopic-assisted volar SL capsulodesis in this study presents an alternative method to address volar SLIL pathology with positive short-term clinical outcomes. Clinical Relevance Arthroscopic-assisted volar SL capsulodesis may be considered in the treatment algorithm for volar SLIL injuries.

Abstract
Background Wrist arthroscopy has become increasingly popular for diagnosing and treating traumatic wrist injuries. How wrist arthroscopy has influenced the daily practice of wrist surgeons remains unclear. The objective of this study was to evaluate the role of wrist arthroscopy for the diagnosis and treatment of traumatic wrist injuries among members of the International Wrist Arthroscopy Society (IWAS). Methods An online survey was conducted among IWAS members between August and November 2021 with questions regarding the diagnostic and therapeutic importance of wrist arthroscopy. Questions focused on traumatic injuries of the triangular fibrocartilage complex (TFCC) and scapholunate ligament (SLL). Multiple-choice questions were presented in the form of a Likert scale. The primary outcome was respondent agreement, defined as 80% answering similarly. Results The survey was completed by 211 respondents (39% response rate). The majority (81%) were certified or fellowship-trained wrist surgeons. Most respondents (74%) had performed over 100 wrist arthroscopies. Agreement was reached on 4 of the 22 questions. It was agreed that the outcomes of wrist arthroscopy strongly depend on surgeons' experience, that there is sufficient evidence for the diagnostic purposes of wrist arthroscopy, and that wrist arthroscopy is better than magnetic resonance imaging (MRI) for diagnosing TFCC and SLL injuries. No agreement was reached on the preferred treatment of any type of TFCC or SLL injury. Conclusion There is agreement that wrist arthroscopy is superior to MRI for diagnosing traumatic TFCC and SLL injuries, yet experts remain divided on the optimal management. Guidelines need to be developed for the standardization of indications and procedures. Level of Evidence This is a Level III study.

Abstract
A conventional arthroscopic capsuloligamentous repair is a reliable surgical solution in most patients with scapholunate instability. However, this repair does not seem to be sufficient for more advanced injuries. The aim of this study was to evaluate the functional results of a wide arthroscopic dorsal capsuloligamentous repair (WADCLR) in the management of severe scapholunate instability. This was a prospective single-centre study undertaken between March 2019 and May 2021. The primary outcome was the evaluation of the reduction of the radiological deformity and the functional outcomes after WADCLR. A secondary outcome was the evaluation of the effectiveness of this technique in patients with the most severe instability (European Wrist Arthroscopy Society (EWAS) stage 5). The patients were reviewed postoperatively at three, six, and 12 months. The study included 112 patients (70 male and 42 female). Their mean age was 31.6 years (16 to 55). A total of three patients had EWAS stage 3A injuries, 12 had stage 3B injuries, 29 had stage 3C injuries, 56 had stage 4 injuries, and 12 had stage 5 injuries. There was a significant improvement of the radiological signs in all patients with a return to normal values. There was also a significant improvement in all aspects of function except for flexion, in which the mean increase was negligible (0.18° on average). There was also a significant improvement in all criteria for patients with a stage 5 injury, except for some limitation of extension, flexion, and radial and ulnar deviation, although these showed a trend towards improvement (except for flexion). WADCLR is a minimally invasive, easy, and reproducible technique with few complications, offering a clear improvement in function and a reduction in the radiological deformity at one year postoperatively.

Abstract
Grade 2 scapholunate advanced collapse (SLAC 2) can be treated by proximal row carpectomy with satisfactory results. However, this method is invasive and can limit function. The senior author had proposed an arthroscopic alternative with tendon interposition between the radius and proximal carpal row (arthroscopic interposition tendon arthroplasty [AITA]). However, this arthroscopic technique is technically difficult and requires a risky palmar arthroscopic portal. We report a modification of AITA, the one-loop arthroscopic radiocarpal tendon inter-position (1L-ARTI) that is simpler and needs only dorsal arthroscopic portals.

Abstract
Wrist injuries in the competitive athlete are a common reason for evaluation related to an acute injury or after symptoms have become chronic. While radius- and ulna-sided wrist pain are common topics covered in the literature, middorsal wrist pain is more common than the available literature would suggest. Missed diagnoses and inadequate treatment can significantly increase athlete morbidity and delay return to play. The goal of this article was to review the differential diagnosis of middorsal wrist pain in the athlete and discuss the diagnosis, treatment, and early return to play for each condition.

Abstract
The treatment of chronic scapholunate ligament tears in patients with high demand, such as young athletes, is difficult as traditional techniques are associated with some loss of wrist motion and grip strength. This retrospective investigation studied young athletes (≤20 years old) with chronic scapholunate ligament lesions and a minimum follow-up of 24 months, treated with a modified Viegas dorsal capsuloplasty. Twenty-six young athletes (mean age 17 years) were included. A partial scapholunate ligament tear (Geissler III) was seen in 25 patients. At the last follow-up, a significantly different improvement was seen in all measured parameters and all patients could return to their original competitive activity, within 6 months (range 4-12) after surgery.Level of evidence: IV.

Abstract
This study reviews the efficacy of a reconstruction to address scapholunate dissociation using an anterior and posterior approach with a hybrid synthetic tape/tendon weave between the trapezium, scaphoid, lunate and radius: an anatomical front and back (ANAFAB) repair. This repair is a compilation of the components of a number of previously reported repair techniques, and based on published kinematic evidence. It aims to restore the anatomical mechanical constraints on both anterior and posterior aspects of the carpus. Patients were immobilized in a cast for 6 weeks, but no stabilizing wires were used. Ten patients have undergone the reconstruction and were assessed at a minimum 24-month follow-up. They achieved excellent realignment of the carpus, a postoperative median scapholunate gap of 3 mm and a recovery of more than 75% of grip strength and range of motion. No patient required secondary surgery or treatment related to the carpal stabilization. Level of evidence: IV.

Abstract
Scapholunate ligament tear is most frequently encountered in the aftermath of trauma in supination and extension of the wrist. It generates chronic instability, leading to osteoarthritis. It may be associated with fracture of the distal epiphysis of the radius or of the scaphoid. These lesions are often difficult to diagnose, especially in early stages. Treatment of chronic scapholunate ligament lesions before onset of osteoarthritis is a challenge for the surgeon. To date, recommendations are for open reconstruction or repair, which can improve pain and grip strength, but very often at the cost of wrist stiffness. The advent of arthroscopy has completely changed the understanding and treatment of these lesions. The present review focuses on recent contributions to the anatomy of the scapholunate complex and the anatomopathology of these dissociations, and explores classical treatments and the emerging role of arthroscopy. We shall seek to answer five questions: (1) What are the anatomical bases of the scapholunate complex, (2) What is the initial clinical and paraclinical work-up for scapholunate dissociations, and how are they to be classified, (3) What are the classical treatments for scapholunate dissociation, (4) What are the technical principles and results of arthroscopic treatment, (5) What are the limits and perspectives of arthroscopic treatment?

Abstract
Background Management of chronic isolated scapholunate interosseous ligament (SLIL) injuries has generated a substantial volume of low-quality literature with descriptions of multiple new surgical techniques, and the impact of instability pattern and the optimal surgical technique remain unclear. The primary goal of this review was to compare clinical, radiographic and patient-rated outcomes between current surgical techniques. Methods We performed a systematic literature search using multiple databases. We analyzed clinical, radiographic and patient-reported outcomes. We used a fixed-effects model weighted by sample size with combined outcomes estimated via least squares means with 95% confidence intervals. We also performed a subgroup analysis of static versus dynamic instability. Results We assessed 805 procedures from 37 study groups, with 429 procedures used in subgroup analysis. There were no statistically significant differences in outcomes between surgical techniques or in subgroup analysis. Overall, postoperative wrist flexion and pain scores decreased, and grip strength and patient-rated outcomes improved. Conclusion Compared to overall preoperative values, modest improvements in pain score, grip strength and functional outcome scores were obtained from a range of reconstructive procedures performed for chronic isolated SLIL injuries. No significant differences could be ascertained between surgical techniques, potentially owing to the low quality of evidence and procedure heterogeneity. This study provides accurate preoperative reference values for future studies, highlights the controversial clinical impact of instability classification, and the need for higher-quality multicentre or collaborative trials to improve our understanding and management of this common injury.

Arthroscopic scapholunate dorsal capsulodesis: A 30-patient case series comparing postoperative splint immobilization versus immobilization and connected K-wiring. HAND SURGERY & REHABILITATION 2018; 37:352-357.

Abstract
The aim of this retrospective study was to compare the results of arthroscopic dorsal capsulodesis performed with or without temporary K-wiring to treat patients who had sustained scapholunate ligament injuries. Our case series included 30 patients with an average age of 37 years (range: 19-55) of whom 12 were female. Dorsal scapholunate capsulodesis was carried out in all patients. In 15 patients, splint immobilization only was used (group I). For the remaining 15 patients, supplementary scapholunate and scaphocapitate K-wiring was performed (group II). The outcomes, whether K-wiring was used or not, were not as good as the outcomes of other published studies. In our study, the reported QuickDASH score was on average higher than 20/100, pain score was higher than 2/10, grip strength was less than 70% of the contralateral side. There was one postoperative complication in the first group and three complications in the second group; five cases of DISI were reported in the first group and three in the second group. There were no significant differences between the two groups. Based on our findings, supplementary K-wiring is not necessary when a dorsal scapholunate capsulodesis is performed. The outcomes of our study were not as good as those of other published series, potentially due to a shorter follow-up and the more severe ligament injuries in our case series.

Abstract
Purpose We retrospectively evaluated the results of all arthroscopic dorsal scapholunate (SL) capsuloplasty without pinning in patients presenting predynamic instability and dorsal capsuloscapholunate septum lesions on arthro-computed tomography scan after failed medical treatment. Materials and Methods Fifteen patients, mean age 34.3 years, underwent all arthroscopically assisted dorsal capsuloplasty. Patients were assessed preoperatively and postoperatively by a clinical (pain, Watson's test, range of motion, and strength), functional (quick disabilities of the arm, shoulder, and hand), patient-rated wrist evaluation, and Mayo wrist score scores), and radiological (SL gap and dorsal intercalated segmental instability [DISI]) examination. SL tears were evaluated during surgery by European Wrist Arthroscopy Society (EWAS) classification. Results The mean follow-up period was 20.2 months (range, 12-41). Preoperatively, positive Watson's test was noted in all cases. DISI deformity was noted in three cases without any SL gap. The SL instability was graded EWAS IIIB ( n = 8) or EWAS IIIC ( n = 7). Postoperatively, positive Watson's test was noted in only one case. Activity pain decreased from 7.8 preoperatively to 2.4 postoperatively. Range of motion in flexion-extension increased from 92.9 degrees preoperatively to 126.2 degrees postoperatively. Grip strength increased from 24.2 preoperatively to 38.2 postoperatively. At final follow-up, range of motion in flexion-extension and grip strength were estimated at 87 and 91% compared with contralateral side, respectively. All functional scores were significantly improved at the last follow-up. No radiographic SL gapping in grip views or DISI deformity was noted. Discussion Cadaveric studies demonstrated that the dorsal portion of SL ligament is critical for the stability of the SL complex. The entire arthroscopic SL capsuloplasty technique provides reliable results for pain relief, avoiding postoperative stiffness associated with open procedures. It is an alternative technique for patients with predynamic SL instability after failure of medical management and shall not prelude the resort to any further open procedure. Level of Evidence This is a level IV, case series.

Abstract
Objectives To measure the quality of life, the time to work return, and clinical, functional, and radiographic parameters of patients treated with dorsal capsulodesis associated with scapholunate (SL) reconstruction, assisted by arthroscopy. Methods From January 2015 to September 2016, 14 adult patients with SL dissociation underwent surgical treatment with the SL reconstruction procedure assisted by arthroscopy, using the new technique proposed in this study. All patients were assessed by the occupational therapy department at regular intervals after surgery and performed the same sequence of rehabilitation. The parameters analyzed were: range of motion (ROM), Disability of the Arm, Shoulder, and Hand (DASH), visual analog scale (VAS), and radiographic analysis to visualize the pre- and postoperative SL gap and the pre- and postoperative dorsal intercalated segment instability (DISI) deformity the. The complications and the time to return to work activities were described. Results The follow-up time was 12 months (3-17). The ROM averaged 321° (96.9% of the normal side). VAS was 1.79/10 (1-6). DASH was 6.50/100 (1-30). The time to work return work was 4.42 months (2-17). As for complications, one patient developed SLAC, and underwent four-corner fusion one year after ligament reconstruction. Currently, he has experienced pain relief, with a functional range of motion of the wrist, and has not yet returned to professional activities.The preoperative SL gap was 4.29 mm (2-7); in the postoperative period, it was 1.79 mm (1-4). The DISI deformity was present in ten patients with SL angle > 70° (preoperative) and it was corrected after surgery, in all patients. SLAC stage I was identified in a patient. Arthroscopy was performed in all cases. The SL instability was classified as Geissler grade III in four cases and as grade IV in ten cases. Conclusion The new approach (dorsal capsulodesis associated with SL reconstruction, assisted by arthroscopy) presented in this study is safe and effective in the treatment of SL dissociation, since it offers satisfactory clinical, radiographic and functional results, showing low rates of complications. For patients, it allows the return to their social and professional activities, and increases their life quality.

Abstract
Background Tears of the dorsal radiocarpal capsule at the level of the scapholunate interosseous ligament (SLIL) have recently been described in association with predynamic scapholunate instability. Purpose The aim of this anatomical study of the dorsal capsulo-scapholunate septum (DCSS) was to examine the connection of the dorsal capsule on the SLIL and dorsal intercarpal ligament (DICL). Methods Fourteen fresh frozen wrists from seven adult cadavers were dissected through a dorsal approach. Any dorsal attachment of the DICL on the dorsal surface of the SLIL, that is, the DCSS, was identified and measured (height and width). Results The DCSS was consistently found connecting the DICL, the dorsal radiocarpal capsule, and the dorsal aspect of the SLIL. It was formed by the confluence of three arches like intersecting ribs in gothic architecture. The mean dimensions of the DCSS were 5.8 mm in height and 4.0 mm in maximum width. Conclusion The DCSS that connects the SLIL with the dorsal capsule and DICL could be a constant structure of dorsal wrist. Further investigation is required to study the histology of the DCSS and its biomechanical properties in isolation to know whether the DCSS can be considered a secondary stabilizer of the scapholunate ligament complex. Clinical Relevance A better anatomical knowledge of scapholunate ligament complex could help understand and manage instability of the wrist.

Abstract
Purpose A proximal avulsion of the radiocarpal capsule (PARC) is a cause of persisting posttraumatic wrist pain. This lesion is often overlooked and left untreated during wrist arthroscopy. Materials and Methods A record review was performed on 13 patients with this lesion who underwent diagnostic wrist arthroscopy after failed conservative treatment. We retrospectively reviewed the results of an arthroscopic repair method in 13 patients. Results In 11 of the 13 consecutive cases the lesion was sutured using an arthroscopic dorsal capsule-ligamentous repair technique. Postoperatively, all high-demand patients were able to return to their previous sports. Discussion The PARC lesion is usually overlooked during diagnostic arthroscopy since it may be covered by synovial or fibrous tissue. It often coexists with scapholunate ligament or triangular fibrocartilage complex injuries. This lesion is amenable to an arthroscopic repair with satisfactory clinical results.

The Role of Dynamic (4D) CT in the Detection of Scapholunate Ligament Injury. J Wrist Surg 2016; 5:306-310.

Abstract
Background Scapholunate (SL) interosseus ligament injuries detected at an early stage could allow the surgeon to prevent progression through the spectrum of injury that leads to instability, and eventually osteoarthritis. We contend that early instability following injury can be detected by visualizing the relative motions and distances between the involved carpal bones (scaphoid and lunate) during wrist movement in vivo. The purpose of this study is to demonstrate the utility of dynamic CT (i.e., 4DCT) in diagnosing SL interosseus ligament injuries in two patients with clinical suspicion of SL interosseus ligament injury during flexion-extension (FE), radial-ulnar (RU) deviation, and dart thrower's (DT) motions. Case Description 4DCT images obtained from two individual cases were analyzed to assess the proximity between the scaphoid and lunate during wrist motion using standard image processing techniques. Proximity maps representing the distances between the scaphoid and lunate bones during each phase of wrist motion were determined. These maps provide insight into the severity of diastasis (large separation) and location of diastasis at the SL joint. The patients' proximity maps indicated dorsal diastasis and subtle uniform diastasis. Literature Review Complex musculoskeletal abnormalities, such as wrist joint instabilities, elude diagnosis during 2D fluoroscopy due to the 3D geometry of the anatomy and the inherent 3D nature of the bony kinematics. Even the most recent advances with MR arthrography lack good correlation with wrist arthroscopy. Wrist arthroscopy remains the gold standard for diagnosis to assess for intercarpal laxity. However, arthroscopy is an invasive procedure subjecting patients to the risk of infection, nerve injury, pain, and stiffness. Clinical Relevance 4DCT allows noninvasive characterization of where ligament injuries likely occur; this may allow for a more selective surgical treatment directed at the specific location of the tear.

Abstract
The dorsal capsulo-scapholunate septum (DCSS) is an anatomic structure linking the scapholunate ligament and the dorsal capsule of the wrist. It should be a predynamic scapholunate stabilizer. The authors, using their experience for the extrinsic ligaments testing, suggest an arthroscopic testing of the DCSS. The status could be graded in 4 stages according to the trampoline aspect and to the fiber attachment. They report a preliminary study on a series of 53 arthroscopies made between January 2014 and December 2015 with evaluation of scapholunate ligament instability and DCSS laxity. There is a significant correlation between the lesional stage of the DCSS and the arthroscopic predynamic scapholunate instability stage (P<0.01).
