Project description:BackgroundThe indications for repair of rupture of the ulnar collateral ligament (UCL) of the metacarpophalangeal (MP) joint of the thumb are debated. We studied factors predictive of operative treatment.MethodsIn this retrospective study, we queried the research database from 3 affiliated urban hospitals in a single city in the United States and identified 383 patients with a thumb MP UCL injury. We recorded age, sex, treating surgeon, and whether or not a magnetic resonance imaging (MRI) was ordered. If radiographs showed a concomitant avulsion fracture, we measured fragment size and displacement. Multivariable logistic regression was used to identify factors independently associated with surgery.ResultsSurgery was independently associated with older patient age, widely displaced fractures (≥2 mm), and obtaining an MRI. Two specific surgeons were less likely to operate. Compared with patients without a fracture, fractures without displacement were less likely to have surgery.ConclusionsThe rate of surgery for acute thumb MP UCL injury varies based on patient characteristics and the individual treating surgeon. Variation might decrease with improved diagnostic techniques and consideration of practice guidelines. Future studies are needed to determine the patients and injuries that will benefit most from surgery.

Project description:BackgroundThe clinical diagnosis of thumb ulnar collateral ligament disruption has been based on joint angulation during valgus stress testing. This report describes a definitive method of distinguishing between complete and partial ulnar collateral ligament injuries by quantifying translation of the proximal phalanx on the metacarpal head during valgus stress testing.MethodsSixty-two cadaveric thumbs underwent standardized valgus stress testing under fluoroscopy with the ulnar collateral ligament intact, following an isolated release of the proper ulnar collateral ligament, and following a combined release of both the proper and the accessory ulnar collateral ligament (complete ulnar collateral ligament release). Following complete ulnar collateral ligament release, the final thirty-seven thumbs were also analyzed after the application of a valgus force sufficient to cause 45° of valgus angulation at the metacarpophalangeal joint to model more severe soft-tissue injury. Two independent reviewers measured coronal plane joint angulation (in degrees), ulnar joint line gap formation (in millimeters), and radial translation of the proximal phalanx on the metacarpal head (in millimeters) on digital fluoroscopic images that had been randomized.ResultsCoronal angulation across the stressed metacarpophalangeal joint progressively increased through the stages of the testing protocol: ulnar collateral ligament intact (average [and standard deviation], 20° ± 8.1°), release of the proper ulnar collateral ligament (average, 23° ± 8.3°), and complete ulnar collateral ligament release (average, 30° ± 8.9°) (p < 0.01 for each comparison). Similarly, gap formation increased from the measurement in the intact state (5.1 ± 1.3 mm), to that following proper ulnar collateral ligament release (5.7 ± 1.5 mm), to that following complete ulnar collateral ligament release (7.2 ± 1.5 mm) (p < 0.01 for each comparison). Radial translation of the proximal phalanx on the metacarpal head did not increase after isolated release of the proper ulnar collateral ligament (1.6 ± 0.8 mm vs. 1.5 ± 0.9 mm in the intact state). There was a significant increase in translation following release of the complete ulnar collateral ligament complex (3.0 ± 0.9 mm; p < 0.01) and an additional increase after forcible angulation of the joint to 45° (4.1 ± 0.9 mm; p < 0.01). Translation 2 mm greater than that in the stressed control was 100% specific for complete disruption of the ulnar collateral ligament complex.ConclusionsWhile transection of the proper ulnar collateral ligament leads to an increase in metacarpophalangeal joint angulation and gapping on stress fluoroscopic evaluation, only release of both the accessory and the proper ulnar collateral ligament significantly increases translation of the proximal phalanx on the metacarpal head.

Project description:Background: The optimal management of pediatric thumb ulnar collateral ligament (UCL) avulsion fractures remains poorly defined. The purpose of this study was to elucidate patient outcomes based on initial management and fracture characteristics. Methods: A retrospective study of all patients younger than 18 years of age presenting with a thumb UCL avulsion fracture was performed. Patients were grouped by their initial management. The primary outcome of the study was time to return to full activity. Fractures were characterized by articular surface involvement, displacement, and rotation. Results: Forty-seven patients with thumb UCL avulsion fractures were identified. Ten patients underwent surgery as initial treatment; all healed without complication, with a mean recovery time of 6.2 ± 1.8 weeks. Thirty-seven patients were treated conservatively; although most healed, the recovery time was longer (9.2 ± 8.3 weeks, adjusted hazard ratio = 2.3, 95% confidence interval = 1.0-5.5). Four cases (11%) required conversion to surgery that all healed without complications. Fractures treated with immobilization alone were significantly smaller, less displaced, and less rotated than those initially treated with surgery; however, 19 fractures that would have met criteria for surgery were treated with immobilization and successfully healed within 7.1 ± 2.9 weeks. Fracture characteristics did not predict which patients would fail conservative treatment or have prolonged recovery times. Conclusions: While surgery provided definitive treatment without delay in recovery, immobilization may not be an unreasonable treatment choice even for patients with large or displaced fractures. In cases where patients failed immobilization, surgery as a second-line treatment had good results.

Project description:Background: The aim of this study was to evaluate the effectiveness of interventions for acute complete rupture of the ulnar collateral ligament (UCL) of the thumb in adults. Methods: The following databases were searched: MEDLINE and EMBASE via OVID, CINAHL and SPORTDiscus via EBSCO, from database inception to 31 st January 2018. Inclusion criteria were: (i) randomised controlled clinical trials (RCTs) or study of intervention with a comparator; (ii) participants with diagnosis of acute complete rupture of the UCL of the thumb; (iii) participants aged 18 years of age or older at enrolment; and (iv) published in a peer-reviewed English-language journal. Results: In total, six studies were identified for inclusion after screening. All studies had a high risk of bias. Three studies were retrospective comparative case series which compared two different surgical techniques (bone anchor versus pull out suture, suture versus pull out suture, suture versus steel wire). Of these studies, three were RCTs, two of which compared different rehabilitation regimes in patients managed surgically (plaster versus early mobilization, new spica versus standard spica). The remaining RCT compared two different rehabilitation regimes in a mixed group of surgically/non-surgically treated patients. The RCT comparing a standard spica with a new spica demonstrated a statistically significant improvement in outcomes with the new spica at all time points (range of motion, Dreiser index and VAS); this was also the only study to provide sufficient outcome data for further analysis. Conclusion: There is no prospective evidence comparing surgery to non-operative treatment for acute complete ruptures of the ulnar collateral ligament of the thumb. There is weak evidence to suggest that early mobilisation may be beneficial following surgical repair. Further research is necessary to better define which patients benefit from which specific interventions.

Project description:This Technical Note aimed to present a surgical technique of ulnar collateral ligament (UCL) shoelace repair using suture anchors and double suture tapes in combination with internal bracing to correct UCL instability along with epiphyseal avulsion of the medial epicondyle in throwing athletes Skeletally immature throwing athletes playing baseball and softball are at a risk of sustaining medial epicondyle epiphyseal separation that can result in UCL instability, predisposing to elbow UCL disruption later. There are several surgical techniques that can restore elbow UCL function and stability. In cases where large fragments of the medial epicondyle are present in skeletally immature athletes, the residual bony fragment and the shortened, chronically injured UCL make surgical treatment quite challenging. Recent studies have shown that UCL repair with internal bracing can effectively treat acute UCL injury. However, this procedure is not ideal for restoring large disruption of the UCL such as fragmentation. Here, we present a surgical technique of UCL shoelace repair using suture anchors with double suture tapes in combination with internal bracing for correcting UCL instability concurrent with epiphyseal fragmentation of medial epicondyle in throwing athletes.

Project description:Reconstruction of the ulnar collateral ligament (UCL) remains the gold standard for treating overhead throwing athletes with valgus instability secondary to UCL pathology. Although surgical techniques for reconstruction have evolved over time, current methods allow 90% of patients to return to their preinjury level of activity. Despite encouraging results with reconstruction, UCL repair remains a valuable treatment option for patients with UCL pathology fitting specific criteria. There are a number of advantages associated with a direct repair, and further, the development of collagen-coated sutures for ligament repair augmentation makes this procedure an attractive surgical option under the correct circumstances. This article provides a detailed description and video demonstration of the surgical steps used to perform a UCL repair with suture augmentation.

Project description:Purpose and hypothesisAlthough sex- and gender-specific analyses have been gaining more attention during the last years they have rarely been performed in orthopaedic literature. The primary purpose of this study was to investigate whether for injuries of the UCL the specific location of the rupture is influenced by sex. A secondary study question addressed the sex-independent effect of trauma intensity on the rupture site of the UCL.MethodsThis study is a retrospective analysis of all patients with either a proximal or distal bony avulsion or with a mid-substance tear or ligament avulsion of the UCL treated surgically between 1992 and 2015 at two level-I trauma centres. Trauma mechanisms leading to the UCL injury were classified into the following categories: (1) blunt trauma (i.e., strains), (2) low-velocity injuries (e.g., fall from standing height, assaults), and (3) high-velocity injuries (e.g., sports injuries, motor vehicle accidents). After reviewing the surgical records, patients were divided into three groups, depending upon the ligament rupture site: (1) mid-substance tears, (2) proximal ligament or bony avulsions and (3) distal ligament or bony avulsions. Dependencies between the specific rupture site and the explanatory variables (sex, age, and trauma intensity) were evaluated using ?2 test and logistic regression analysis.ResultsIn total, 1582 patients (1094 males, 488 females) met the inclusion criteria. Mean age was 41 years (range: 9-90 years). Taking into account the effects of sex on trauma intensity (p<0.001) and of trauma intensity on rupture site (p<0.001), mid-substance tears occurred more frequently in women, whereas men were more prone to distal ligament or bony avulsions (p<0.001). In other words, sex and rupture site correlated due to the effects of sex on trauma intensity and of trauma intensity on rupture site, but taking into account those effects there still was a significant effect of sex on rupture site.ConclusionsThe results of this study demonstrate that with regression analysis both sex and trauma intensity allow to predict rupture site in UCL injuries.

Project description:OBJECTIVE:Several studies have been published regarding the treatment of medial ulnar collateral ligament (MUCL) injuries for professional overhead athletes. However, there is a paucity of data regarding non-professional athletes. The aim of this systematic review was to compare the rate of outcome scores and complications of conservative versus operative treatments both in non-professional athletes and in non-sport-related trauma patients with MUCL lesions. METHODS:A systematic review of the published literature was performed by applying the PRISMA guidelines. A search was conducted using three databases: Medline, Science Direct, and Web of Science. The keywords used were "ulnar collateral ligament injury," "elbow," "surgery," and "conservative treatment". Patients were divided into three groups: patients who underwent conservative treatment (C-group), surgical treatment (S-group), and surgery after a failed conservative treatment (C&S-group). Clinical outcomes were analyzed: Disability of Arm, Shoulder and Hand (DASH), Conway scale, Carson score, and Kerlan-Jobe Orthopaedic Clinic score (KJOC). RESULTS:A total of 15 studies were included, evaluating 513 patients. Although good and excellent outcomes were found for most patients during daily and/or sport activities, independently of the type of treatment, the C-group had better results. Excellent results were found in 98.8% of the C-group, in 88.1% of the S-group, and in 87.7% of the C&S-group. The complication rate in the C-group was statistically higher compared to the S and C&S groups (P <?0.001). However, its complication rate was higher with lower patient satisfaction. CONCLUSIONS:There is insufficient evidence to establish statistically significant differences in the effects of conservative versus surgical treatments on the functional outcomes of patients with MUCL lesions. However, a period of rehabilitation therapy and the functional request of the single injured subject are useful to discern which patients genuinely require MUCL surgical repair.

Project description:Ulnar collateral ligament (UCL) injuries lead to pain and loss of performance in the thrower's elbow. Ulnar collateral ligament reconstruction (UCLR) is a reliable treatment option for the symptomatic, deficient UCL. Injury to the UCL usually occurs because of chronic accumulation of microtrauma, although acute ruptures occur and an acute-on-chronic presentation is also common.Computerized databases, references from pertinent articles, and research institutions were searched for all studies using the search terms ulnar collateral ligament from 1970 until 2015.Clinical review.Level 5.All studies reporting outcomes for UCLR are level 4. Most modern fixation methodologies appear to be biomechanically and clinically equivalent. Viable graft choices include ipsilateral palmaris longus tendon autograft, gracilis or semitendinosus autograft, and allograft. Clinical studies report excellent outcomes of UCLR for both recreational and elite level athletes with regard to return to sport and postoperative performance. Complications, although rare, include graft rerupture or attenuation, ulnar nerve symptoms, stiffness, pain, and/or weakness leading to decreased performance.Injuries to the UCL have become commonplace among pitchers. Nonoperative treatment should be attempted, but the limited studies have not shown promising results. Operative treatment can be performed with several techniques, with retrospective studies showing promising results. Complications include ulnar neuropathy as well as failure to return to sport. Detailed preoperative planning, meticulous surgical technique, and a comprehensive rehabilitation program are essential components to achieving a satisfactory result.

Project description:The prevalence of ulnar collateral ligament injuries and reconstructions among overhead throwing athletes has significantly risen in recent years. Surgical reconstruction has become the main treatment modality for athletes who have failed conservative treatment and wish to return to their sport. There has been an increased interest in graft augmentation in ligament reconstruction surgeries as surgeons search for ways to decrease the chance of graft failure. Augmented graft techniques have been described for other procedures. We present a technique that incorporates a cross-linked suture tape into either a palmaris longus or gracilis tendon autograft or allograft for ulnar collateral ligament reconstruction. This may allow for a biomechanically stronger construct because it appears this is the case in other settings. The goal is that this would lead to decreased rates of failure or possibly allow athletes to return at an accelerated rate.
