Project description:The arthroscopic technique most frequently used in acute scapholunate instability is reduction and fixation with Kirschner wires. To repair the injured ligament, open surgery and dorsal capsular plication are recommended, but this procedure has the risk of damaging secondary dorsal stabilizers, the dorsal blood supply, and the proprioceptive innervation of the posterior interosseous nerve. In this report, we present an all-arthroscopic technique of a dorsal reconstruction of the scapholunate interosseous ligament for scapholunate instability using a tape by tethering the scaphoid to the lunate.

Project description:Scapholunate ligament (SLL) injury is the most frequent injury of the intrinsic carpal ligaments. The dorsal part of the SLL is the most important part for the stability of the scapholunate joint, and tears of this part and at least one of its secondary capsular attachments cause scapholunate dissociation. The arthroscopic technique most frequently used for acute injuries is reduction and fixation with Kirschner wires, and techniques that involve a primary repair of the injured ligament are performed by open surgery with efficient results. However, they lead to significant stiffness of the wrist due to injury to the soft tissue caused by damage to the secondary dorsal stabilizers; the dorsal blood supply; and in many cases, the proprioceptive innervation of the posterior interosseous nerve. We present an all-arthroscopic technique for the direct repair of acute injuries of the dorsal part of the SLL using bone anchors, complemented by a dorsal arthroscopic plication that reconstructs the dorsal capsulo-scapholunate septum of the scapholunate complex.

Project description:Background The dorsal capsuloligamentous scapholunate septum (DCSS) is a confluence of the dorsal capsule, the dorsal intercarpal ligament (DIC), and the scapholunate interosseous ligament (SLIOL). It appears to play a role in the stability of the scapholunate articulation. The purpose of this study was to describe the anatomical basis for this structure and to investigate its role in scapholunate instability through sectioning of this structure followed by an arthroscopic and fluoroscopic analysis. Material and Methods In the anatomical part of the study we dissected 3 fresh cadaver wrists to examine the anatomy of the DCSS. In the arthroscopic part of the study we assessed the EWAS grade of SL instability before and after sectioning the DCSS and measured the scapholunate and radiolunate angles fluoroscopically. Results Sectioning the DCSS increased the EWAS grade of SL instability but did not affect the scapholunate gap, the scapholunate angle or radiolunate angle. Conclusion We have demonstrated that there is a distinct structure that is separate from the dorsal capsule, which we have labeled the Dorsal Capsuloligamentous Scapholunate Septum. We believe that the DCSS is a previously unreported secondary stabilizer of the SL joint which may have therapeutic and prognostic implications.

Project description:Treatment of scapho-lunate (SL) injuries is still a challenge for the surgeon, especially in chronic cases. The aim of the study isto experimentally cut, specific portions of scapholunate ligament and extrinsic ligaments and check their corresponding arthroscopic finding in order to understand the pathogenesis and develop a new classification system which is an evolution of the present arthroscopic classifications. Materials and Methods Thirteen cadaver wrists were studied under arthroscopy. Different portions of the scapho-lunate ligament were subsequently sectioned. In group A the sectioning sequence was: anterior SLIOL, RSC, LRL, SLIOL's proximal and posterior, DIC, DRC ligament and ST ligaments (8 cases). In group B it was: SLIOL's posterior and proximal, DIC, SLIOL's anterior, LRL, RSCL, DRC, ST ligaments (5 cases). The anatomo-pathological findings after each sectioning were correlated to the classification system proposed (Table 1). Results In group A, stage 3A was obtained when SL ligament's volar and intermediate portion and/ or SC/LRL ligaments were sectioned. A stage 3C was obtained when section of posterior SLIOL was sectioned as well. A stage IV when the DIC was also sectioned. In group B a stage 3B was obtained by cutting intermediate, posterior portion of the SLIOL ligament and DIC. A stage 3C was obtained when the anterior part of the SLIOL was also sectioned. In all cases, sectioning of the SLIOL lead to a stage 3C only if associated with sectioning of at least one of the extrinsic stabilizers (DIC or SC/LRL). Sectioning of DIC and SC ligament, in addition to SLIOL led to an arthroscopic stage IV. When ST, DRC and TH ligaments were also sectioned significant radiological signs appeared (stage V). Conclusions This study helps us to understand the anatomo-pathological scapho-lunate lesions in their different stages of partial lesions. Commonly called scapho-lunate lesions are complex, involving also extrinsic ligaments.

Project description:Carpal instabilities continue to be a controversial topic in hand surgery. Accurate diagnosis of the ligament injuries is usually difficult without an arthroscopic evaluation. Few studies have focused on the diagnosis and proper management of simultaneous scapholunate (SL) and lunotriquetral (LT) ligament tears. This is an uncommon injury that leads to marked disability and chronic wrist pain. This is essentially a "floating lunate" and indicates a severe ligamentous lesion. Thirteen patients (six female and seven male) with complete SL and LT tears and with gross arthroscopic dynamic carpal instability were included in the present study. None of the patients showed radiographic evidence of lunate dislocation. One patient presented acutely and was operated on 3 days after the injury. The average time from the initial injury to the arthroscopy for the other 12 patients was 13.5 months (range 1.5-84 months). All patients underwent arthroscopic debridement of the SL and LT ligaments coupled with percutaneous pinning (two 0.045-in. Kirschner wires) in both joints. At the final follow-up, the average range of motion was 50 degrees of flexion, 54 degrees of extension, 77 degrees of pronation, 80 degrees of supination, 25 degrees of ulnar deviation, and 15 degrees of radial deviation. The average final grip strength was 67% from the non-affected side. All patients had negative shifting tests at final follow-up. Furthermore, there was no evidence of any static or dynamic instability in all the patients except for one patient who developed a volar intercalated segment instability 8 months after the surgery. At the final follow-up, ten patients had no pain, one had mild pain, and two experienced moderate pain.

Project description:Acute partial injury of the anterior cruciate ligament (ACL) is a challenging condition without a standard treatment. Although ACL reconstruction provided a better outcome previously, recent studies have shown that preserving the ACL stump yields promising results in terms of better vascularization, proprioception, and ligamentization. ACL augmentation is becoming more popular. Therefore, we propose a technique to augment an acute partial ACL injury with synthetic suture material to stabilize the unstable cruciate ligament. The suture material acts as a structural tie for ACL healing without any need for external immobilization. This technique is beneficial in preserving the natural ACL stump and autograft, creating a narrow bone tunnel, and providing a good cosmetic outcome.

Project description:BACKGROUND:Scapholunate ligament injuries are highly challenging injuries to treat. Great uncertainly remains in determining which operative procedures are most effective. Furthermore, there is no consensus on whether surgical intervention changes the natural course of scapholunate injuries. METHODS:The authors present their assessment of scapholunate injuries and the senior author's preferred surgical techniques. Surgical videos are included. The authors' postoperative management is described. RESULTS:Operative procedures are selected based on the patient's timing and pattern of injury, degree of associated carpal changes and arthritis, and goals. CONCLUSION:Over the past 20 years, the senior author has had good success with these techniques, but prospective, longterm outcome studies are needed to critically assess whether these surgical techniques improve patients' long-term function and pain.

Project description:PurposeTreatment of subacute and chronic static scapholunate instability remains challenging. We aimed to determine 5- to 10-year outcomes of dorsal intercarpal ligament capsulodesis with scapholunate interosseous ligament repair for subacute and chronic static scapholunate instability.MethodsSix patients with subacute and chronic static scapholunate instability underwent dorsal intercarpal ligament capsulodesis with scapholunate interosseous ligament repair between 2011 and 2015, and 5 of them were followed for at least 5 years after surgery. The clinical and radiological results were retrospectively investigated. All patients were male, and the mean age at surgery was 37 years (range, 21-47 years). The mean period from injury to surgery was 26.2 months (range, 2-113 months). The surgical procedure was a modification of a method reported by Szabo et al.ResultsThe mean postoperative follow-up period was 8.1 years (range, 5.1-9.5 years). Median Disabilities of the Arm, Shoulder, and Hand and Mayo wrist scores improved from 23.3 to 1.7 and from 55 to 80, respectively, from before surgery to the final follow-up. Although the median flexion angle tended to be smaller, the median extension angle tended to be greater than before surgery. The median percent grip strength increased from 72.3% before surgery to 99.2% at the final follow-up. The median scapholunate gap improved from 4.2 mm before surgery to 2.1 mm at the final follow-up. The median scapholunate angle also improved from 95.7° before surgery to 71.3° at the final follow-up. Osteoarthritic changes were observed in 2 of 5 patients at the final follow-up.ConclusionsThe scapholunate gap in all patients was within the normal range after a mean of 8.1 years of follow-up. Dorsal intercarpal ligament capsulodesis with scapholunate interosseous ligament repair is considered a good alternative for subacute and chronic static scapholunate instability based on these 5- to 10-year outcomes.Type of study/level of evidenceTherapeutic IV.

Project description:ObjectiveThe purpose of this report is to describe a patient with scapholunate advanced collapse (SLAC) of the wrist.Clinical featuresA 38-year-old man presented to a chiropractic teaching clinic with right wrist pain after falling off of the tailgate of a truck 7 years prior. The mechanism of injury was a fall on an outstretched hand. Ultrasonography and radiography were performed, which demonstrated abnormal lunate kinematics and scapholunate interval diastasis associated with a clenched-fist maneuver. These findings were consistent with SLAC.Intervention and outcomeFollowing the diagnosis of SLAC, the wrist was splinted. Conservative care consisting of physical therapy included paraffin dips, therapeutic ultrasound, and stretching. The patient received only minimal alleviation of pain, and a surgical consultation was obtained. The patient elected surgical intervention, utilizing the proximal row carpectomy procedure.ConclusionThis case demonstrates a patient with chronic wrist pain, with progression to carpal instability, which ultimately manifested as SLAC. We demonstrate, utilizing multiple imaging modalities, both preoperative and postoperative findings. To our knowledge, this is the first case to describe the use of diagnostic ultrasonography in the evaluation of the proximal row carpectomy procedure.

Project description:BackgroundOptimal treatment of chronic scapholunate (SL) instability remains controversial. Many surgical techniques have been proposed with varied results in subsequent case series; however, there is limited evidence demonstrating the relative effectiveness of the different treatment options.Questions/purposesWe conducted a systematic review of the English literature to compare outcomes from capsulodesis and ligament reconstruction for treatment of chronic scapholunate instability.MethodsAn electronic database search using keywords associated with scapholunate ligament instability was performed. A total of 511 studies were identified. All studies with scapholunate ligament tears >4 weeks after the initial injury were included in the review. Data extracted included patient demographics, wrist range of motion, and radiographic outcome measures.ResultsA total of 308 patients from 11 studies met the inclusion criteria and were included in the study. The average time to surgery from initial injury was 11 months. There was no significant difference in wrist flexion or extension after capsulodesis or reconstruction. The weighted mean for postoperative wrist extension/flexion was 56°/45.6° in the capsulodesis group and 40.9°/47.3° in the reconstruction group. Pooled means of SL angle and SL gap were 60.3° and 3.44 mm after capsulodesis and 56.5 and 2.72 mm after reconstruction, respectively.ConclusionsThis systematic review failed to demonstrate any significant difference in outcomes from capsulodesis or reconstruction for treatment of chronic scapholunate instability. However, the retrospective studies examined were notably heterogeneous in design with high estimates of variance. Further prospective trials are necessary to determine an ideal treatment strategy.
