Corticosteroid Injection With and Without Local Anesthetic for the Treatment of Trigger Finger: A Randomized Clinical Trial.

PURPOSE: This study aimed to report pain during and following injection for trigger finger as well as failure to resolve triggering. We hypothesized that a corticosteroid injection alone would be equally or less painful compared with the standard combination of corticosteroid and lidocaine for the treatment of trigger fingers, and there would be no difference in the resolution of triggering. METHODS: Our study was a prospective, single-blinded, randomized controlled trial at a single institution, comprising 76 patients with a diagnosis of trigger finger. Each treatment group consisted of 38 patients. Patients were randomized to receive either a betamethasone (1 mL, 6 mg) injection without lidocaine or a betamethasone injection (1 mL, 6 mg) with 1% lidocaine (1 mL). Patients were assessed during injection and at 1 hour, 6 hours, 2 days, and 6 weeks after the injection. The primary outcome was pain measured using a numerical rating scale. The secondary outcome was the rate of failure to resolve symptoms at 6 weeks. RESULTS: There was a statistically significant difference in pain scores between the lidocaine and betamethasone versus betamethasone-only injections during administration (4.6 vs 6.2) and after 1 hour (1.3 vs 2.5). There was no statistically significant difference in pain scores after 6 hours (1.5 vs 2.0) and 2 days (0.7 vs 0.6) or in failure rate at the 6-week time point (21% vs 18%). CONCLUSIONS: This study showed that there is a statistically significant difference in pain during and shortly after injection when using a steroid with lidocaine versus steroid alone for the treatment of trigger finger, but that difference may not be clinically relevant. There was no significant difference in the failure rate between the treatments. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Five-Year Follow-up of Adolescent Gymnasts After Surgical Treatment of Osteochondritis Dissecans of the Elbow.

PURPOSE: Elbow osteochondritis dissecans (OCD) is well-studied in throwing athletes; however, there are limited data regarding gymnasts with capitellar OCD lesions. We aimed to determine the overall rate of return to competition following surgical treatment of capitellar OCD lesions and to determine the relationship, if any, between arthroscopic grade of lesion and ability to return to competition. METHODS: A medical chart Current Procedural Terminology query from 2000 to 2016 yielded data on 55 competitive adolescent gymnasts who were treated surgically for elbow OCD lesions in a total of 69 elbows. Retrospective chart review was used to collect data on preoperative and postoperative symptoms and surgical treatment. Patients were contacted to complete questionnaires (Modified Andrews Elbow Scoring System, Disabilities of the Arm, Shoulder, and Hand) on return to sport. Current elbow function and follow-up data were available for 40 of 69 elbows. RESULTS: Average age at time of surgery was 12.1 years with 18 of 55 (33%) of patients competing at a pre-elite level of gymnastics (level 9 or 10 of 10) before surgery. Nine out of 31 gymansts (29%) underwent bilateral surgery for OCD lesions. Average OCD lesion size was 10 mm. Thirty-one of 40 elbows (78%) were treated with debridement back to a stable cartilage rim with microfracture, and nine of 40 elbows (22%) were treated with debridement alone. Thirty-six of 40 patients (90% returned to competitive gymnastics with all returning patients competing at or above the same level after surgery. Among the patients who were followed up, 29 of 30 patients (97%) reported some difficulty with specific events on return to competition. CONCLUSIONS: The rate of return to sport for gymnasts at 90% is similar to that observed in other sports. This study suggests that elbow OCD lesions are not career-ending injuries for adolescent gymnasts; however, gymnasts should not expect a fully asymptomatic return to all events in a sport. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Efficacy of a single, image-guided corticosteroid injection for glenohumeral arthritis.

BACKGROUND: Limited data are available on the efficacy of cortisone injections for glenohumeral osteoarthritis (GHOA). The amount and longevity of pain relief provided by a single cortisone injection are unclear. Additionally, it remains uncertain how the severity of radiographic GHOA and patient-reported function and pain levels impact the efficacy of an injection. Therefore, we sought to describe the relief provided by a single, image-guided glenohumeral injection in patients with GHOA. We hypothesized that patients with more severe radiographic GHOA and poorer baseline shoulder function would require earlier secondary intervention. METHODS: Patients with symptomatic GHOA who elected to receive a corticosteroid injection for pain relief were prospectively enrolled. A phone interview was conducted to record the baseline Oxford Shoulder Score (OSS) and visual analog scale (VAS) score prior to the injection, as well as the OSS and VAS score at months 1, 2, 3, 4, 6, 9, and 12 after the injection. The endpoint of the study occurred when patients required a second injection, progressed to surgery, or reached month 12. Patients were grouped by their respective baseline OSS (mild vs. moderate or severe) and Samilson-Prieto radiographic classification (mild, moderate, or severe) for analysis. RESULTS: We analyzed 30 shoulders (29 patients). Of the patients, 52% were men. The average age was 66.1 years. No significant difference in overall survival (defined as no additional intervention) was seen between groups based on either the OSS or Samilson-Prieto grade. Additionally, the OSS and VAS score at each follow-up were compared with baseline values. For the entire cohort, a clinically significant difference was seen between baseline and months 1-4 for the OSS and between baseline and months 1-4, 6, 9, and 12 for the VAS score. DISCUSSION: This study aimed to determine the efficacy of corticosteroid injections for GHOA. There were no differences in the need for secondary intervention in this population based on the severity of either the OSS or the Samilson-Prieto radiographic classification. However, patients with more severe shoulder dysfunction based on the OSS did experience statistically significantly greater symptomatic relief than patients with milder dysfunction. Additionally, following a single injection, patients in this cohort experienced statistically and clinically relevant improvements in shoulder function and pain up to 4 months after injection.

Enigmatic and Unusual Cases of Upper Extremity Pain: Mislabeling As Malingerers.

With the intricate anatomy of the hand and upper extremity, there are many possible etiologies of pain. In addition, one must be alert to conditions typically affecting other areas of the body presenting in the hand and upper extremity. To add to the complexity of diagnosis, one must also be aware of potential secondary gains. With this in mind, a thorough history, physical examination, and broad differential can help avoid mislabeling patients with uncommon ailments. In this article, we present 4 cases of unusual causes of hand and upper extremity pain.

A Pediatric Medial Epicondyle Fracture Cadaveric Study Comparing Standard AP Radiographic View With the Distal Humerus Axial View.

BACKGROUND: Controversy exists with regard to the amount of fracture displacement that warrants surgical fixation of medial epicondyle fractures. Inaccurate determination of degree of displacement on plain radiographs may account for the disputed management. Recently, a novel distal humerus axial radiograph technique has been developed to improve the accuracy of radiographs. The purposes of the study are 2-fold; to identify the anatomic orientation of the medial elbow epicondyle physis in children and to compare the accuracy of determining fracture displacement between axial radiographs and standard anterior-posterior (AP) radiographs in a cadaveric medial epicondyle fracture model. METHODS: Twelve pediatric elbow computed tomographic scans and 19 pediatric elbow magnetic resonance imaging scans were analyzed for the orientation of the medial elbow physis. After determining the correct orientation, 15 adult cadaveric medial epicondyle fracture models were created at displacements of 2, 5, 10 mm, and maximum displacement with elbow at 90 degrees of flexion. A linear mixed model regression analysis was used to compare displacement based on the axial versus the AP radiographic methods. RESULTS: The medial epicondyle physis was found to be a posterior structure angled distally at ~36 degrees (range, 10.7 to 49.6) and angled posteriorly at 45 degrees (range, 32.2 to 59). The AP radiograph significantly underestimated displacement relative to the axial radiograph at 5 mm [mean difference, -1.6; 95% confidence interval (CI), -2.9 to -0.3], at 10 mm (mean difference, -4.5; 95% CI, -5.8 to -3.2 mm), and at maximal displacement (mean, 15 mm; range, 13 to 20 mm) (mean difference, -7.1; 95% CI, -8.3 to -5.8). CONCLUSIONS: The medial epicondyle physis of the distal humerus is a posterior structure angled distally and posteriorly. When displacement was >5 mm, the distal humerus axial radiograph technique was significantly more accurate than the AP radiograph technique at determining actual fracture displacement in our adult cadaveric fracture models. Therefore, we recommend clinicians to include the axial radiograph view during the evaluation of patients with medial epicondyle fractures. CLINICAL RELEVANCE: This study provides further insight into the location and orientation of the medial humeral epicondyle physis, and further supports the improved accuracy of the distal humerus axial radiograph at detecting displacement in medial epicondyle fractures.

Progression of Authorship of Scientific Articles in The Journal of Hand Surgery, 1985-2015.

PURPOSE: For scientists, authorship is academic currency. Authorship characteristics have been studied in a subset of the surgical and medical literature, but trends in the specialty of hand surgery have not yet been investigated. Specifically, a longitudinal analysis of number, educational training, sex, and geographical origin of authors has not been conducted. We explored the progression of authorship of scientific articles in a leading hand surgery journal. METHODS: We recorded number of authors, number of references, degrees, and sex of the first and senior authors as well as geographical origin of the corresponding author in The Journal of Hand Surgery in 1985, 1995, 2005, and 2015. All original work was analyzed. RESULTS: A total of 892 articles were reviewed. The mean number of authors per article increased significantly from 2.6 in 1985 to 3.9 in 2015 and the number of references increased significantly from 13.7 in 1985 to 22.6 in 2015. There was a significant increase in the proportion of first authors with an MD/PhD, PhD, master's or bachelor's degree since 1985. During that same time period, a decrease in the proportion of first authors who held solely an MD was seen. There was a significant increase in proportion of the number of last authors with an MD/PhD, PhD or Master's degree in that same time period. There has been significant growth in publications originating from the "Far East" and "Other" regions, with 4.2% and 5.0% of publications, respectively, in 1985 having increased to 10.3% and 7.4% of publications, respectively, in 2015. Female first authorship significantly increased over the study period from 7.9% in 1985 to 22.1% of publications in 2015. CONCLUSIONS: There has been a significant increase in number of authors per article in The Journal of Hand Surgery. Similar to other studies, we noted shifts in the degrees most commonly held by authors, an increase in references per article, and a greater representation of international authors in the hand surgery. In addition, the proportion of manuscripts written by female authors has increased in the past 30 years, with the largest increase occurring between 2005 and 2015. CLINICAL RELEVANCE: This manuscript strives to provide further insight into the changing characteristics of authors contributing to the hand surgery literature. With increased pressure to publish in academia, it is important to understand how publishing author characteristics have evolved over time. In addition, the published literature of a field could be considered one repository of the insights and advancements of the field. One would hope that the authors contributing to that literature are a deep and wide reflection of the people working in that field. Analyzing authorship is one way to assess the breadth and depth of contributions from the profession.

A pediatric medial epicondyle fracture study using fresh frozen adult cadavers comparing fracture displacement and loss of terminal elbow extension.

Medial epicondyle fractures are the 3rd most common pediatric elbow fractures. Regardless of treatment method, some degree of elbow motion loss has been reported. The purpose of our study was to determine the relationship between the amount of anterior fracture displacement and loss of elbow passive extension in an adult cadaveric medial epicondyle fracture model. Fifteen fresh frozen adult cadavers were procured to create fracture models at scenarios of 2, 5, 10 mm, and maximum displacement. Terminal elbow extension was recorded for each cadaveric model at each fracture scenario. A linear mixed model regression analysis was used to test the association between fracture displacement and loss of terminal elbow passive extension. At 2 mm of displacement, the average loss of terminal extension was 3.89°; at 5 mm, it was 7°; at 10 mm, it was 10.7°; at maximum displacement (~15 mm), it was 17°. A statistically significant positive linear association between fracture displacement and loss of terminal elbow extension was observed (5 mm of displacement = loss of ~4.7°). In our fracture model, when the medial epicondyle displaced anteriorly, we noticed a change in the tension of the medial collateral ligaments which lead to a decrease in terminal elbow extension. However, this only contributed partially to the loss of motion observed clinically in the literature. Even though our findings did not support the recommendation of surgical intervention to prevent loss of elbow motion in medial epicondyle fractures, we still encourage physicians to consider the consequence of displacement and its potential influence of elbow range of motion.

Slipped capital femoral epiphysis: what's new?

Slipped capital femoral epiphysis (SCFE) is a common hip disorder among adolescents, whereby the epiphysis is displaced posteriorly and inferiorly to the metaphysis. Treatment modalities aim to stabilize the epiphysis, prevent further slippage, and avoid complications associated with long-term morbidity, such as osteonecrosis and chondrolysis. Controversy exists with SCFE regarding prophylactic fixation of the contralateral, painless, normal hip, the role of femoroacetabular impingement with SCFE, and whether in situ fixation is the best treatment method for SCFE. This article presents and discusses the latest diagnostic and treatment modalities for SCFE.
