We will review the anatomy of this injury, the resulting pathologic biomechanics, and address the diagnosis, staging, and treatment of SLL injuries. Isometric contraction of abductor pollicis longus, extensor carpi radialis longus (ECRL), and flexor carpi ulnaris induced midcarpal supination. Curated learning paths created by our anatomy experts, 1000s of high quality anatomy illustrations and articles. Intracarpal soft-tissue lesions associated with an intra-articular fracture of the distal end of the radius. It has a relatively wide range of attachment along the glenoid labrum and extends to the inferomedial part of the surgical neck of the humerus. This one, as the radioscaphocapitate ligament, appears to be a secondary stabilizer between the scaphoid and lunate, being the scapholunate ligament the primary stabilizer [ 9, 16 ]. Attempted scapholunate arthrodesis for chronic scapholunate dissociation. Wrist arthroscopy has been an essential tool for the assessment and treatment of SLL injuries.3942 When wrist arthroscopy is performed for instability, it is important to perform both radiocarpal and midcarpal arthroscopy. Register now Unlike traditional ligaments, the glenohumeral ligaments are not purely tensile. The palmar ulnocarpal group of ligaments include the ulnotriquetral, ulnocapitate and ulnolunate ligaments. Dreant N, Dautel G. Development of a arthroscopic severity score for scapholunate instability. At the distal articulation of the joint are three other ligamentous attachments that aids in stabilizing the joint. A final group of instability, SLAC, can be seen when the scaphoid is displaced and there is evidence of arthritis.29 SLAC has its own spectrum based on the progression of arthritis. In stage 6 SLL injuries, the ligament is irreparable, there is fixed, irreducible carpal malalignment, and the cartilage is damaged. Treatment of scapholunate dissociation by stage. The remainder of the FCR tendon is pulled through a hole made in the radiotriquetral ligament and sutured back onto the lunate portion of the tendon. Bickert B, Sauerbier M, Germann G. Scapholunate ligament repair using the Mitek bone anchor. Arthroplasty of the hand and wrist. Roberto Grujii MD Anatomy and human movement: structure and function (6th ed.). Treatment of radiocarpal degenerative osteoarthritis by radioscaph-olunate arthrodesis and distal scaphoidectomy. A fourth stage has been added to include SLAC wrists with radiolunate arthritis.101 For wrists with arthritis between the radial styloid and the distal pole of the scaphoid, a radial styloidectomy can relieve pain that may occur with radial deviation of the wrist.29 The radial styloidectomy can be performed open or arthroscopically through the 1,2 portal.102 When performing a radial styloidectomy, it is important to protect the radiocarpal ligaments and avoid creating additional instability.2 The treatments for stage 2 SLAC wrist are intended to remove pressure from the arthritic cartilage of the distal radius scaphoid fossa. The largest and longest of the three ligaments is the inferior glenohumeral ligament. For more information about the anatomy and movements of the wrist joint, take a look below: Among the most common injuries in clinical practice are the injuries of the wrist joint. These lines were described by Linn et al and can be used to assess carpal malalignment.33 Disruption of these normally smooth lines occurs when malalignment is present (Figure 2). Nagle D, Benson L. Wrist arthroscopy: indications and results. Herbert TJ. In the close-packed position, the radiocarpal joint is extended with a slight degree of abduction/radial deviation, while the loose-packed (or resting) position is neutral with a small degree of adduction/ulnar deviation. The source of the insult is most often sports related or the result of a traumatic event. Also associated with FOOSH injuries are acromioclavicular sprains. http://creativecommons.org/licenses/by-nc/3.0/, Radiographs do not reveal injury but physical exam is positive for pain with wrist use, Radiographs will reveal the injury under stressed or dynamic loading, Plain radiographs will show scaphoid displacement without stressed or dynamic loading, Radiographs show static scapholunate dissociation with arthritic changes at the wrist, Hemorrhage and attenuation of the interosseous ligament viewed from the radiocarpal joint and no step-off at the midcarpal joint, Hemorrhage and attenuation of the interosseous ligament at the radiocarpal joint; there is step-off viewed at the midcarpal joint and the probe can be placed between the scaphoid and lunate, Step-off between the scaphoid and lunate is viewed at both the radiocarpal and midcarpal joints, and the probe can be easily placed and rotated between the scaphoid and lunate, Gross instability is noted at the scapholunate interval and a 2.7-mm arthroscope can be placed in the scapholunate diastasis, Arthroscopic debridement and electrothermal shrinkage, Open repair of SLL with K-wire stabilization, Complete, irreparable SLL injury with normal alignment. When all of the components are functioning, this ellipsoid joint allows movements along two axes (transverse and sagittal). In the proximal row, the scapholunate and the lunotriquetral joints each have a complex of transverse ligaments; a palmar ligament, a dorsal ligament, and a proximal fibrocartilaginous membrane. Bain GI, Watts AC. Moran SL, Cooney WP, Berger RA, Strickland J. Capsulodesis for the treatment of chronic scapholunate instability. The SLL is completely torn and malalignment exists. Partial scapholunate ligament injuries treated with arthroscopic debridement and thermal shrinkage. Darlis NA, Weiser RW, Sotereanos DG. It can achieve a vast range of motions and also facilitates the completion of fine motor tasks. Midcarpal arthritis developed in 12.5% of the patients at 37 months average follow-up.97 Limited intercarpal arthrodesis is recommended for patients with stage 5 SLL injuries who are seeking a reduction in their wrist pain and are willing to lose some but not all wrist range of motion. The wrist is protected in a thumb spica cast for 6 weeks and then in a removable splint for an additional 6 weeks. FOIA It also limits the adduction/ulnar deviation of the wrist joint. Philadelphia, PA: Wolters Kluwer Health/Lippincott, Williams & Wilkins. the contents by NLM or the National Institutes of Health. Once the SLL is incompetent, the scaphoid flexes and displaces dorsally, and the lunate extends. Uninterrupted Gilula Lines 1, 2, and 3 in a wrist with normal alignment. If imaging has already been performed and is suggestive of injury, but the exam is completely benign, there may be no need for further treatment. Treatment of SLL injuries requires intricate understanding of wrist anatomy and biomechanics. The inverted cone-shaped band helps to anchor the clavicle to the axial skeleton by inserting on the costal cartilage of the first rib. Rosenwasser MP, Paul SB, Froimson AI. In stage 3 SLL injuries, the ligament is completely ruptured and irreparable. Since the first description of the extrinsic ligaments of the wrist, their functions have continued to be defined. Watson HK, Ballet FL. and grab your free ultimate anatomy study guide! If there is pancarpal arthritis and the patient has significant pain, a total wrist arthrodesis can be beneficial. Luegmair M, Saffar P. Scaphocapitate arthrodesis for treatment of scapholunate instability in manual workers. The triquetrum has a small articular surface on its proximal surface, which may or may not articulate with the triangular fibrocartilage complex. Traumatic instability of the wrist. The transverse humeral ligament transforms the bicipital groove into a canal as it travels in the groove, above the long biceps tendon. Grounded on academic literature and research, validated by experts, and trusted by more than 2 million users. 1Department of Orthopaedic Surgery, McGovern Medical School, University of Texas Health Science Center, Houston, TX, USA, moc.liamg@akponokrd, 2Division of Plastic and Reconstructive Surgery, University of Florida College of Medicine, Gainesville, FL, USA, moc.oohay@mihcyevrah. Chee KG, Chin AYH, Chew EM, Garcia-Elias M. Antipronation spiral tenodesisa surgical technique for the treatment of perilunate instability. In addition to the staging systems defined by Watson et al and Geissler et al, Garcia-Elias et al described another staging system that can be used to guide SLL injury treatment as well (Table 3).31,42,48 The first stage is incomplete SLL injury. Just to ensure everything is clear, the ligaments associated with the shoulder joint include the: The elbow joint is a hinge type joint that may appear to have some degree of rotational motion at the site. All content published on Kenhub is reviewed by medical and anatomy experts. Berger RA, Bishop AT, Bettinger PC. Dreant N, Mathoulin C, Lucchetti R, Pegoli L. Comparison of two arthroscopic classifications for scapholunate instability. Chronic bilateral scapholunate dissociation without symptoms. A SLAC wrist is not always painful and may be an anatomic variant.98100 The treatments for SLAC wrist, often called salvage procedures, depend on the stage of arthritis as defined by Watson and Ballet.29 Stage 1 SLAC wrist exhibits radial styloid beaking, joint space narrowing, and sclerosis between the radial styloid and the distal pole of the scaphoid. (2018). Proximally, the triangular fibrocartilage attaches to the ulnar aspect of the lunate fossa of the radius, ulnar head and ulnar styloid process. 2011;31(1):79-80. The scaphoid flexes almost twice as much as the lunate in the sagittal plane at the radiocarpal joint.3 The lunate has a larger base palmarly than dorsally, resulting in a tendency for the lunate to assume an extended position.4 Due to the oblique orientation of the scaphoid to the longitudinal axis, radial deviation of the carpus at the radiocarpal joint results in flexion of the scaphoid as it articulates with the radius, and ulnar deviation of the carpus results in extension of the scaphoid.3 Through the scapholunate joint, the lunate will flex and extend passively with the scaphoid, but to a lesser degree. Causes: SLL injury, scaphoid fracture, Keinboch's and perilunate injury End result may be SLAC wrist Volar Intercalated Segment Instability (VISI) . However, once the dorsal intercarpal ligament was sectioned, scapholunate instability was noted.11,12 Further research on the ligamentous stability of the dorsal wrist has investigated the role of the dorsal capsule-scapholunate septum (DCSS). The coracohumeral ligament consists of two bands that bridges the coracoid process (dorsolaterally at its base) to the lesser and greater humeral tubercles. Its articulating surface involves three bones the scapula, acromion and humerus. A grade III C lesion is a complete tear of the SLL with reducible widening of the scapholunate space with removal of the probe. At the glenohumeral joint, this injury can result in a tear of the glenoid labrum known as a soft Bankart. In the upper limb, sprains are more common in the elbow and shoulder regions than at other sites. Berger RA. During flexion, the scaphoid and lunate bones glide over the concave articular surface of the distal radius in a posterosuperior direction. Computed tomography (CT) scanning is a useful modality for imaging wrist pathology. These types of falls not only cause damage to the bony structures of the radiocarpal joint, but also to its related ligamentous structures, vessels and nerves. The EWAS Classification of scapholunate tears: an anatomical arthroscopic study. Declan Tempany BSc (Hons) Three-ligament tenodesis for the treatment of scapholunate dissociation: indications and surgical technique. The dorsal radiocarpal ligament is the principal ligament to oppose carpal supination. The radiocarpal joint is enclosed by a two-layered joint capsule which covers the articulation of the osseous components, in addition to some soft tissue structures. Sprains are classified based on the severity of the tear: It should be noted that grade 1 and 2 sprains usually undergo self repair and remodelling after injury. Radsource June 2012. The anatomy of the dorsal capsulo-scapholunate septum: a cadaveric study. (2014). These tissues have included the capsule, the intrinsic ligaments, the extrinsic ligaments, tendons, and bone-ligament-bone autograft.6267 The dorsal capsulodesis was designed to help correct the flexion and pronation that the scaphoid assumes after an SLL injury.

Geissler WB, Freeland AE, Savoie FH, McIntyre LW, Whipple TL. Terry Thomas sign on a wrist PA radiograph showing scapholunate diastasis. This technique is performed through a dorsal midline approach to the wrist. The radiocarpal joint receives its innervation from articular branches of the following nerves; The radiocarpal joint receives its blood supply from the branches of the dorsal and palmar carpal arches. With arthroscopy, the pathology can be visualized, and the synovium and nonviable tissue can be debrided. The general treatment categories include nonoperative management, acute scapholunate repair, scapholunate reconstruction, intercarpal fusions, salvage procedures, and wrist arthrodesis. Combined injuries to the scapholunate and lunotriquetral ligaments can be found on arthroscopy using the rocking chair sign in which the lunate can rock volar and dorsal with the probe when it normally should exhibit no rocking.46 The scaphoid 3D test or scaphoid dorsal dynamic displacement test can be performed arthroscopically to evaluate scapholunate instability if the scaphoid shifts dorsally with regard to the lunate upon pressure at the scaphoid tubercle.47 Arthroscopy can also be useful for the treatment of some SLL injuries, but not all SLL injuries are best treated with arthroscopy. Rotary subluxation of the scaphoid: a spectrum of instability. In the radiocarpal joint, the large concave facet located on the distal end of radius directly articulates with the scaphoid and lunate bones. Orthoinfo.aaos.org. Watson et al described a spectrum of injury resulting from rotary subluxation of the scaphoid.31 Using static and dynamic radiographs, the injuries can be categorized into four groups: predynamic instability, dynamic instability, static scapholunate dissociation, and SLAC (Table 1). An official website of the United States government. Hom S, Ruby LK. This view is obtained similar to the PA view but with the wrist held fully supinated on the film, and the hand is pulled into a fist. A skin incision is made longitudinally just ulnar to Listers tubercle. Abduction is a more limited movement of this joint. Last reviewed: December 22, 2022 government site. The SLAC wrist: scapholunate advanced collapse pattern of degenerative arthritis. As such, the ligaments associated with this articulation will be discussed. The incision is then carried back to the radial side of the wrist splitting the fibers of the dorsal intercarpal ligament. The unique shape and orientation of the scaphoid and the radioscaphoid articulation allow a unique motion that has been called the dart-throwers motion.5 This motion occurs when the hand moves from an extended and radially deviated position to the flexed and ulnarly deviated position, as when a person throws a dart. RSC radioscaphocapitate ligament. In adduction the rotation of the scaphoid bone enables the lunate to move laterally and situate completely distal to the inferior surface of radius. Notes: (A) The bones of the wrist: trapezium (1), trapezoid (2), capitate (3), hamate (4), scaphoid (5), lunate (6), triquetrum (7), pisiform (8), radius (9), ulna (10), and the bases of the metacarpals (11). excising entire proximal row of carpal . It is distinctly separated from the radioscaphocapitate ligament and as such, an obvious space called the interligamentous sulcus . The scapular foramen serves as a conduit for the suprascapular nerve, while the corresponding vasculature travels superior to the ligament. While the extrinsic ligaments typically have midsubstance ruptures, the intrinsic ligaments often avulse from the cartilage of the carpal bone.1 There are seven volar extrinsic ligaments of the wrist: radioscaphoid, radioscaphocapitate, long radiolunate, short radiolunate, ulnocapitate, ulnotriquetral, and ulnolunate.1,2 There is one dorsal extrinsic ligament of the wrist: the dorsal radiotriquetral.2. Stage 1: Partial Scapholunate Ligament Injury. Once imaging has been obtained for a wrist with suspected scapholunate injury, there are key characteristics to look for. Both of these actions contribute dynamic stability to the carpus.17,18 Proprioception and neuromuscular control also play a role in the stability of the scapholunate joint, in particular. The best treatment options are those that provide some range of motion while eliminating pain. CT scanning can help visualize fractures as well as the geometric relationships of the carpal bones to each other. Arising near the clavicular articulating surface of the acromion is the coracoacromial ligament. Part of the ligament integrates with the superior glenohumeral ligament inferiorly, while another portion covers the biceps tendon anterior to the joint. There are extracapsular ligaments and intracapsular ligaments. Feipel V, Rooze M. The capsular ligaments of the wrist: morphology, morphometry and clinical applications. A notable feature of the ligaments of the wrist is that none of them are truly extracapsular; most of them are rather defined as thickenings of the joint capsule, providing it with additional support. The radioscaphocapitate ligament is one of the intracapsular, extrinsic palmar radiocarpal ligaments and a volar stabilizer of the wrist 1-3. Long-term follow-up of modified Blatts capsulodesis for the treatment of scapholunate ligament injuries. Vance RM, Gelberman RH, Braun RM. Netter, F. (2019). Deep to the glenohumeral joint capsule is a group of three ligaments known as the glenohumeral ligaments. Working together, these ligaments serve to prevent palmar translocation of the ulnar carpal bones and allow the hand to follow the radius in its movements. In static scapholunate dissociation, the injury is evident on plain radiographs. These wrists are described as having SLAC.31 The patient may or may not have pain, and it is important to determine if any surgical treatment is necessary. In stage 1 SLL injuries, the ligament is only partially ruptured. Gross anatomy The radioscaphocapitate ligament connects the palmar surface of the distal radius with the scaphoid and the capitate bone, running in an oblique orientation and composes the radial and a part of the volar radiocarpal joint capsule 1-4. from the shoulders to the fingers and everything in between. There are two options to do this: the proximal row carpectomy (PRC) or scaphoidectomy with midcarpal fusion. Outcomes of dorsal capsulodesis and tenodesis for treatment of scapholunate instability. Garcia-Elias et al added the excision of the distal third of the scaphoid to allow for more motion and decrease adjacent joint arthritis at the ST joint.97 Garcia-Elias et al reported on 16 patients who underwent this procedure and found pain relief for daily activities in 81%, 32 of wrist flexion, 35 of wrist extension, 14 of radial deviation, and 19 of ulnar deviation. Kenhub. . The articulation between the distal radius and triquetral bone is indirect and it is facilitated via a biconcave articular disk. Geissler et al developed an arthroscopic-based grading system for carpal interosseous tears (Table 2).42 There has been evolution of the arthroscopic classification of SLL injuries. (B) The dorsal wrist ligaments: dorsalcapitohamate (12), dorsal capitotrapezoid (13), dorsal intercarpal ligament (14), radiotriquetral (15), dorsal lunotriquetral (16), dorsal scapholunate (17), and dorsolateralscaphotrapeziotrapezoid (18). In some stage 4 SLL injuries, the lunate will displace ulnarly due to injury to the radiolunate ligaments. Corella F, Ocampos M, Cerro MD. Full size image. Chronic asymptomatic contralateral wrist scapholunate dissociation. The pair of ligaments known as the trapezoid (located anterolaterally) and conoid (located posteromedially) ligaments is collectively referred to as the coracoclavicular ligaments. Copyright Proximally, the capsule is usually independent of that of distal radioulnar joint, and it attaches to the distal aspects of radius and ulna. Viegas SF, Patterson RM, Todd PD, McCarty P. Load mechanics of the midcarpal joint. Majima M, Horii E, Matsuki H, Hirata H, Genda E. Load transmission through the wrist in the extended position. Notes: The scaphoid line (S) is drawn tangential to the scaphoid along the palmar aspects of the distal and proximal poles of the bone. Injury to the scaphotrapeziotrapezoid liga-ment can be quite challenging to detect. Rothe et al followed 46 patients for an average of 6.3 years after wrist denervation for chronic pain and found 32% were pain-free, 6% experienced no pain relief, and 9% required further surgery.110 There are good treatment options for patients with all stages of SLAC wrist, but none are perfect. Herbert TJ. Range of motion exercises are started afterward. It is located deep to abductor pollicis longus and extensor pollicis brevis tendons 1-6.. It has its insertion along the lateral aspect of the coracoid process. A study performed by De Smet et al on patients who underwent the three-ligament tenodesis for SLL injury found that preexisting arthritic changes and poor scapholunate reductions resulted in poor outcomes.76 Poor scapholunate reductions may have been the result of unidentified radiocarpal instability. Grounded on academic literature and research, validated by experts, and trusted by more than 2 million users. The inferior part travels diagonally between the coronoid process and the olecranon above the trochlear notch (transforming it into the trochlear foramen). Extension happens as the same bones move in the opposite direction with the additional rotation of the scaphoid about its long axis. Author: Along the dart-throwers motion, the scaphoid and lunate remain neutral. Stage 3 leads to disruption of lunotriquetral joint. Constraint and material properties of the subregions of the scapholunate interosseous ligament. Long-term outcomes of dorsal intercarpal ligament capsulodesis for chronic scapholunate dissociation. Cael, C. (2010). Bateni C, Bartolotta R, Richardson M, Mulcahy H, Allan C. Imaging Key Wrist Ligaments: What the Surgeon Needs the Radiologist to Know. Functional anatomy: Musculoskeletal anatomy, kinesiology, and palpation for manual therapists. These wrists exhibit static instability.31 The scaphoid will assume a flexed and pronated position, and the lunate will be in an extended position. Consequently, we set the radioscaphocapitate ligament status as an inclusion criterion to diagnose isolated dislocation of the scaphoid, especially those diagnosed as dorsal dislocation types according to Leung's classification. The quadrate ligament is a small structure that runs from the radial neck to the proximal area of the supinator fossa of the ulna. Scapholunate interosseous ligament injuries: a retrospective review of treatment and outcomes in 82 wrists. Federal government websites often end in .gov or .mil. Ho P-C, Wong CW-Y, Tse WL. Larson TB, Stern PJ. Russell TB. Camus EJ, Van Overstraeten L. Dorsal scapholunate stabilization using Viegas capsulodesis: 25 cases with 26 months-follow-up. The authors report no conflicts of interest in this work. Following the lunate, the triquetral also moves laterally positioning itself immediately distal to the triangular fibrocartilage complex. If the scaphoid and lunate are not in their normal intercalated position, Kirschner wires (K-wires) can be used to joystick the bones to their appropriate positions. Another relatively common elbow injury with a paediatric predilection is a Radial Head Subluxation (Nurses Elbow or Pulled Elbow). A tripartite ligament arising for the styloid process and palmar lip of the radius is the radioscaphocapitate ligament, which be observed on the palmar surface of the wrist. The ECRL has been used previously to reconstruct the SLL through large tunnels in the scaphoid and lunate, with high rates of bone fracture and arthritis progression.36 Brunelli and Brunelli described an SLL reconstruction technique in which both the primary and secondary stabilizers would be strengthened.74 The Brunelli and Brunelli scaphotrapezoid tenodesis is performed by dividing the FCR tendon proximally, maintaining the insertion at the base of the second metacarpal, then threading the tendon from the scaphoid tuberosity palmarly to the neck of the scaphoid dorsally, then inserting the tendon into the dorsal radius at the origin of the dorsal radiocarpal ligament. Each one arises from the anterosuperior and posterosuperior (respectively) aspect of the sternal head of the clavicle and insertlateral to the jugular notch. 4. del Pial F, Tandioy-Delgado F. (Dry) arthroscopic partial wrist arthrodesis: tips and tricks. The comprehensive textbook of clinical biomechanics (2nd ed.). If the scaphocapitate ligament is intact, the interval between these three carpal The narrower deep part arises medial to dorsal tubercle attaches to the lunotriquetral interosseous ligament. While the extrinsic ligaments typically have midsubstance ruptures, the intrinsic ligaments often avulse from the cartilage of the carpal bone. There are treatments available for the full spectrum of SLL injuries from acute injury to chronic SLAC. Del Pial F. Arthroscopic volar capsuloligamentous repair. Soong M, Merrell GA, Ortmann F, Weiss APC. Franchesca Druggan BA, MSc Hagert E, Ljung B-O, Forsgren S. General innervation pattern and sensory corpuscles in the scapholunate interosseous ligament. Midcarpal hemiarthroplasty for wrist arthritis has been shown at 4 years to improve wrist range of motion, grip strength, and patient-reported outcomes.109 In addition to the restorative surgical treatments for SLAC wrist, partial or total wrist denervation procedures are available. At the humeroulnar joint, the ulnar collateral ligament is a three-part triangular structure whose anterior component is stronger and more taut than the posterior part. Arthroscopic scaphoid 3D test for scapholunate instability. The physician should obtain a detailed account of the patients injury. As implied by the nomenclature, these ligaments help to stabilize the triquetrum, lunate and capitate bones by anchoring them to the palmar region of the ulna.
