Recalcitrant Lateral Epicondylitis: A Systematic Review on Current Nonoperative and Operative Treatment Modalities.

Lateral epicondylitis is a common cause of elbow pain that is generally self-limiting. For patients who have persistent symptoms refractory to conservative treatment, there is still no clear consensus on the most favorable treatment modality. The purpose of this systematic review was to synthesize the available literature regarding both nonoperative and operative treatment modalities for recalcitrant lateral epicondylitis (RLE) to provide insight into the efficacy of treatment options. A systematic review was performed in accordance with the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines, where the PubMed, MEDLINE/Ovid, CINAHL, Cochrane, and Scopus databases were queried to identify studies evaluating treatment options for RLE. A total of 27 studies with 1,958 patients were included. Of the reviewed studies, there were a wide variety of treatments including platelet-rich plasma injections, percutaneous tenotomies, and various arthroscopic and open procedures. There are a wide variety of treatment modalities available for RLE that have promising efficacy in the short, medium, and long terms. A comprehensive approach combining evidence-based and patient-centered care is critical for effective management of refractory symptoms. Level IV.

Minimally invasive needle tenotomy vs. platelet rich plasma injection in the treatment of chronic elbow epicondylitis

BackgroundMedial and lateral epicondylitis, characterized by repetitive microtraumas to common flexor and extensor tendons respectively, are common causes of elbow pain in adults. Though symptoms generally are self-limiting, 10% of cases are refractory to conservative management, persisting for greater than 18 months and leading to surgery, which can have increased risk of complications. There is minimal data on sustained pain relief and functional benefit for newer non-surgical management options such as minimally invasive needle tenotomy (MINT) via Tenjet and platelet-rich plasma (PRP) for chronic elbow epicondylitis. Additionally, no previously established correlation exists between MRI severity of chronic epicondylitis with pain and functional improvement in MINT and PRP-treated patients. MethodsA retrospective review of 51 adults (n=23 for Tenjet; n=28 for PRP) was conducted to investigate long-term outcomes in pain relief (via Visual Analog Scale or VAS) and improvements in upper extremity function (via Quick Disability of the Arm, Shoulder, and Hand questionnaire or qDASH). These outcomes were correlated with radiographic evidence of epicondylitis severity, assessed by grade of epicondylitis and percentage thickness of tendon tears. ResultsThere were significant improvements in pain (VAS) but no significant differences in function (qDASH) following MINT and PRP. On average, VAS score improved by 2.6 (p<0.001) post-Tenjet and by 3.8 (p<0.001) post-PRP, combined for all follow-up time points. No adverse events were reported over the entire study. A significantly higher percentage of patient-reported pain relief was noted post-Tenjet at all follow-up time points. VAS and qDASH outcomes post-Tenjet and post-PRP were not correlated with initial MRI severity of epicondylitis. ConclusionsThere are multifactorial benefits of both Tenjet and PRP as safe, non-open surgical modalities that can be used, despite MRI severity, to provide sustained pain relief for patients with refractory elbow epicondylitis.

Ultrasound-Guided Perineural Hydrodissection for the Treatment of Lacertus Fibrosus Syndrome in a Baseball Player: A Case Report.

Lacertus fibrosus Syndrome (LFS) is a rare cause of persistent medial elbow pain in baseball players, often not considered in the initial diagnostic considerations. This case report details a 19-year-old collegiate baseball player who presented with insidious left anterior medial elbow pain, initially diagnosed as biceps tendonitis. The patient did not experience pain relief after six months of conservative management. Sonopalpation during diagnostic ultrasound localized the source of pain to the median nerve at the level of the lacertus fibrosus, and the decision was made to perform ultrasound-guided hydrodissection of the median nerve at this level. The procedure resulted in rapid and sustained symptom relief without the scarring that has been associated with traditional surgical techniques. To date, there has been no study investigating the use of ultrasound-guided hydrodissection targeting lacertus fibrosus. This report highlights the importance of considering LFS in throwing athletes with persistent elbow pain, and advocates for considering ultrasound-guided hydrodissection as a management option for patients with clinical suspicion of LFS.

Prevalence and sex differences in endoscopy-related injuries: comprehensive systematic review and meta-analysis

Background and AimsGastroenterologists are at risk for endoscopy-related injury (ERI). The aim of this meta-analysis was to assess the prevalence, characteristics, and burden of ERI. MethodsWe searched PubMed/Embase/Web of Science databases for studies reporting ERI prevalence among gastrointestinal (GI) endoscopists. The primary outcome was to pool ERI prevalence. We also assessed ERI types and treatments. We compared ERI based on gender. Finally, we compared musculoskeletal injury (MSI) prevalence between GI endoscopists and non-endoscopists. The pooled rates were generated using a proportion meta-analysis with the random-effects model. Prevalence ratios (PR) with the corresponding confidence intervals (CI) were used for comparative data. ResultsWe included 26 studies with 6,246 endoscopists. Overall, ERI prevalence was 67.9% (60.7-74.4). ERI prevalence was 77.8% (55.1-90.9) in advanced endoscopists. A higher trend of ERI prevalence was observed in recent studies (after 2015), 71.7% (63.3-78.9). Neck pain (36.7%) was the most common ERI, followed by low back pain (35.6%) and thumb pain (33.1%). While females reported higher De Quervain tenosynovitis and carpal tunnel syndrome, wrist, thumb, shoulder, and neck pain, males reported higher elbow pain. GI endoscopists had a higher MSI prevalence than non-endoscopists, PR 1.56 (1.01-2.41). Female endoscopists reported higher ERI, PR 1.21 (1.10-1.32). Only 19.1% of endoscopists reported receiving prior ergonomic training. ConclusionsERI is increasingly prevalent in gastroenterology, particularly in female gastroenterologists with significant gender disparities in ERI types noted. These findings underscore the significance of incorporating ergonomic principles into gastroenterology practices to mitigate ERI risks, particularly considering the shortage of gastroenterologists.

Reconstruction of Chronic Monteggia Fracture with Radial Head Excision: A Case Report

Introduction: Chronic Monteggia fracture is a rare and clinically challenging condition, characterized by a non-union fracture of the proximal ulna with dislocation of the radial head. This case report presents the case of a 42-year-old woman with a chronic Monteggia fracture diagnosed 21 years after the initial injury, highlighting the importance of a careful patient history and radiographic investigation. Case presentation: A 42-year-old woman presented with left elbow pain and a history of significant trauma 21 years previously. Physical examination revealed limited range of motion and radiographic examination revealed a nonfused fracture of the proximal ulna with dislocation of the radial head. The patient underwent open reduction and internal fixation (ORIF) reconstruction of the ulna and excision of the radial head. Conclusion: Successful surgical reconstruction of chronic Monteggia fractures results in significant improvements in the patient's function and quality of life. This case report emphasizes the importance of early diagnosis and timely surgical intervention to prevent long-term complications and achieve optimal functional outcomes.

Osseous Triceps Avulsion in a 12-Year-Old Girl: A Case Report.

A 12-year-old girl presented with significant right elbow pain following a fall during soccer which caused an osseous triceps avulsion injury and nondisplaced type II Salter-Harris radial neck fracture. The patient was treated with successful open repair utilizing suture anchor fixation, resulting in full return of function and return to previous activities. Timely and accurate diagnosis and treatment of displaced triceps sleeve avulsion injuries is critical and can result in excellent patient outcomes and return to previous functional level. This unique case contributes to the diagnosis and management of this rare condition in pediatric populations.

Paper 49: Osteochondral Allograft Transplantation for Capitellar Osteochondritis Dissecans: Excellent Patient Reported Outcomes Scores and High Return to Sports

Objectives: Unstable osteochondritis dissecans of the capitellum (OCD-C) is treated surgically, most commonly with loose body removal and marrow stimulation. This treatment has historically been associated with suboptimal return to high-demand upper extremity sports (baseball and gymnastics) and persistent elbow pain. Fresh osteochondral allograft transplantation (OAlloT) is an alternative treatment which restores subchondral bone and articular cartilage without donor site morbidity associated with autograft harvest. The purpose of this study was to evaluate the outcomes of osteochondral allograft transplantation in pediatric patients with unstable OCD-C 10mm or greater in size. Methods: A single-center prospective study was performed of consecutive pediatric patients, less than 19 years of age, with unstable OCD-C 10mm or greater in size treated with primary fresh OCAlloT using pre-cut 10mm, 12mm, or 16mm cores. Imaging, including radiographs and MRI were obtained preoperatively to assess OCD size and characteristics, as well as postoperatively to assess incorporation of the OCA. Patient reported outcome scores (PROs), including sport data, were obtained preoperatively and annually following surgery. Minimum follow-up duration was 2 years. Results: 26 elbows in 24 patients, mean age 13.4 years (11.3 – 17.1 years) met inclusion. The most common primary sport was gymnastics in 11 elbows (42%), baseball/softball in 7 elbows (27%), and cheer in 3 elbow (12%). The majority of patients (88%) played at a competitive level. Median symptom duration prior to presentation was 3 months. The most common presenting symptoms were pain (85%) and mechanical symptoms (81%). Sixteen elbows (62%) presented with a &gt;5° loss of elbow extension compared to the contralateral side. The capitellar physis was open in 23 elbows (88%). OCD location was central in 17 elbows (65%) and far lateral in 9 elbow (35%). Mean MRI size of the OCD was 11 mm in coronal width, 12 mm in sagittal length, and 6 mm in depth. Twelve elbows (48%) had a loose body on MRI. The majority of elbows (22, 85%) were treated with a single allograft plug, while 4 elbows had two allograft plugs transplanted. Median OCA size was 12 mm. There were no infections nor arthrofibrosis. Two elbows (8%) had a secondary surgery, both underwent partial synovectomy and chondroplasty at 14- and 16-months following the primary surgery. Postoperative MRIs were obtained in 15 elbows (58%) and had a mean BOGIE (Boston Osteochondral Graft Incorporation in the Elbow) score of 11, thus documenting a high degree of incorporation. Mean follow-up duration was 40 months (range 25 – 60 months). All patients had preoperative, 1-year, and 2-year PROs (Table 1). 21 elbows (81%) had returned to sports at 1-year postoperatively9, and all but 1 patient had returned to sports by 2 years following surgery. Forty-five percent of gymnasts returned to gymnastics, while the remaining pursued different sports. Five of 6 baseball players (83%) returned to baseball. Conclusions: OCAlloT as a treatment for OCD-C is a procedure associated with low rates of complications, excellent graft incorporation, high elbow function and patient satisfaction, and overall high rates of return to sports at 2-years. Return to sports, particularly among gymnasts was less than 50% in this series, which we attribute to a combination of factors, including loss of training and competition time at a critical time for an elite gymnast as well as physician counseling on alternative sports with less stress on the elbow. Continued patient follow-up is ongoing and will be critical to the assessment of this treatment on the mid- and long-term outcomes in these young athletes. [Figure: see text]

A CASE REPORT ON THE EFFECTS OF CYRIAX TECHNIQUE (DEEP FRICTION MASSAGE ) APPROACH TO REDUCE PAIN ON LATERAL EPICONDYLITIS

Background – tennis elbow (lateral epicondylitis) is one of the most common problems of the arm.[1] It is a work-related or sport-related pain disorder with macroscopic and microscopic tears in the extensor carpi radialis brevis [2]. Deep tendon friction (DTF) is a specific type of connective tissue massage which is applied precisely to the soft tissue structures. Deep tendon friction massage is a combination of Mill’s manipulation and is performed immediately after the DTF.[3] The purpose of this case report is to highlight the implementation of cyriax approach in lateral epicondylitis.Objective – reduction of elbow pain and improves rotational limitations. This helps in enhancing the functional activities.

Comparison of Mulligan Mobilization with Movement and Progressive Strengthening Exercises in Patient with Lateral Epicondylitis

Background: Lateral epicondylitis, commonly known as tennis elbow, is the most prevalent cause of elbow pain. Both Mulligan Mobilization with Movement (MWM) and Progressive Resistive Exercises (PRE) have shown effectiveness in treating lateral epicondylitis individually. This study aims to compare the effects of these two interventions to determine which is more effective in managing lateral epicondylitis. Objective: To compare the effects of Mulligan Mobilization with Movement and Progressive Resistive Exercises in relieving pain, improving functional disability, and enhancing pain-free grip strength in patients with lateral epicondylitis. Methods: A randomized clinical trial was conducted on 33 patients with symptomatic tennis elbow from July 2020 to January 2021 at the Bone and Joint Center and Khyaban Medical Center. Participants were randomly assigned to Group A (n=16) receiving Mulligan Mobilization with Movement and conventional physiotherapy, and Group B (n=17) receiving Progressive Resistive Exercises and conventional therapy. Patients were assessed using the Visual Analogue Scale (VAS), Patient-Rated Tennis Elbow Evaluation (PRTEE), and hand dynamometer to measure pain intensity, functional status, and grip strength at baseline, after 5 sessions, 10 sessions, and at a 6-week follow-up. Data were analyzed using SPSS version 25. Results: Both groups showed significant improvements within group analyses. Group A showed a more substantial reduction in VAS scores and PRTEE scores, with median VAS scores decreasing from 7 to 2 (p=0.001) and PRTEE scores improving from 41 to 8 (p=0.001). Group B demonstrated greater improvements in pain-free grip strength, with median values increasing significantly at all time points (p&lt;0.05). Between-group analysis revealed that Group A had more significant improvements in VAS and PRTEE scores, while Group B had more significant improvements in pain-free grip strength. Conclusion: Mulligan Mobilization with Movement was more effective in reducing pain and improving functional status in patients with lateral epicondylitis compared to Progressive Resistive Exercises. However, Progressive Resistive Exercises were more effective in enhancing pain-free grip strength. These findings suggest the importance of tailored treatment approaches based on individual patient needs.

Cross-cultural adaptation, validation and psychometric properties of the Arabic version of the Nordic Musculoskeletal Questionnaire in office working population from Saudi Arabia

BackgroundOffice-workers who suffer from musculoskeletal pain/disability may experience reduced productivity and absenteeism from work. The Nordic Musculoskeletal Questionnaire (NMQ) is a valid, simple screening tool for the history and presence of self-perceived musculoskeletal symptoms in both general public and occupational settings. ObjectiveTo translate and culturally adapt the NMQ into Arabic language and examine its psychometric properties. MethodsThe published guidelines were followed to translate and adapt the NMQ into Arabic using a forward-backward process. Construct validity involved comparing NMQ responses with disability-related musculoskeletal questionnaires in different body regions, including the Neck Disability Index (NDI), Oswestry Disability Index (ODI), Quick-Disability of the Arm, Shoulder, and Hand (Quick-DASH), and Reduced Western Ontario and McMaster Universities Osteoarthritis Index (ArWOMAC). The reliability was evaluated using Cronbach's alpha for internal consistency and prevalence-adjusted bias-adjusted kappa (PABAK) for test–retest reliability. ResultsThe Arabic NMQ (Ar-NMQ) revealed excellent internal consistency (Cronbach's alpha = 0.85). For the test-retest reliability, the PABAK coefficient ranged between 0.50 and 1. The Ar-NMQ demonstrated strong construct validity. Participants reporting neck pain showed significantly elevated disability scores on the NDI (p < 0.05), while those with back pain exhibited higher ODI scores (p < 0.05). Moreover, individuals reporting shoulder, elbow, and wrist pain and disability displayed elevated Quick-DASH scores (p < 0.05). Similarly, participants reporting hip/thighs, knees, and ankle/feet pain/disability demonstrated significantly higher disability in ArWOMAC (p < 0.05). ConclusionThe NMQ was successfully translated and adapted into Arabic language, providing a reliable and valid instrument for assessing pain in specific body regions in the Arabic-speaking population.

Early detection of myocardial infarction with reference to baseline levels during health: impact on biological variation of high-sensitivity cardiac troponin.

A 78-year-old male was seen in the emergency department (ED) with chest pain. Fifteen months earlier, he had presented to the ED with shoulder and elbow pain. High-sensitivity cardiac troponin I (hs-cTnI) testing was conducted at that time, which produced normal results of 10 and 13ng/L (cutoff <48ng/L). During the current admission, his electrocardiogram was unremarkable, with a borderline prolonged PR interval noted. The patient's hs-cTnI results were 25, 47, and 254ng/L at 0, 1, and 7 hours, respectively. He was diagnosed with demand ischemia and admitted to the hospital. The detection of acute myocardial infarction in this case was made during the first sample collection (t=0), despite the fact that this result was well within the normal range.

The effects of the addition of Mulligan mobilization with movement to exercise on elbow pain and function associated with lateral elbow tendinopathy

BackgroundMulligan mobilization with movement (MWM) and eccentric exercise (EE) have been shown to be effective for the treatment of chronic lateral elbow tendinopathy (LET). However, the addition of MWM to EE effects on LET remained unknown. The objective of the study was to determine the effects of adding of Mulligan mobilization with movement to eccentric exercise for the treatment of LET. MethodsIn this quasi-experimental study, thirty participants with unilateral LET were assigned into two groups: 15 in MWM (received MWM + EE) (7 M and 8 F, mean age 36.8 ± 8.3 years) and 15 in EE (9 M and 6 F, mean age 46 ± 8.1 years). Both groups received education about painful activities and eccentric exercise, while the MWM group received MWM with the same eccentric exercise as the EE group. The visual analog scale (VAS) and the patient-rated tennis elbow evaluation (PRTEE) were used to assess pain and upper limb function, respectively, at baseline and at the end of 4 weeks. The data was analyzed using an independent t-test and a paired t-test. ResultsThere was no significant difference (p > 0.05) between groups at baseline. At the end of 4 weeks, significant and clinically meaningful improvements in pain and function were observed for both groups (p < 0.001); however, MWM group showed much better results in VAS (p < 0.001, d = 1.3) and PRTEE (p < 0.001, d = 5.2) ConclusionThis study showed that adding MWM to eccentric exercise resulted in enhanced pain reduction and improved function of the upper limb.

Lateral elbow magnetic resonance imaging findings in patients without pain complaints

Magnetic resonance imaging (MRI) can help evaluate lateral epicondylitis; however, abnormal findings on MRI are not always consistent with the symptoms. The occurrence of such abnormal MRI findings at the lateral side of the elbow in patients without pain remains unclear. Therefore, the purpose of this study was to investigate the MRI findings of the lateral elbow joint in patients with no complaints of pain in the elbow joint. We retrospectively identified 152 patients who had undergone MRI of the area including the elbow from July 2015 to January 2022. We excluded patients with pain in the elbow area and those with diagnosis of diseases that could affect MRI findings at the lateral elbow. The presence of lateral collateral ligament complex (LCLC) and common extensor tendon (CET) lesions on MRI was assessed by two reviewers. In total, 22 patients (12 men and 10 women) were included in the analysis. The mean age of the patients was 54 years. Five patients, all ≥65 years old, had abnormal findings related to the LCLC or CET on MRI. Abnormal LCLC and CET findings on MRI can be encountered in older patients even in the absence of elbow pain.

Safety and effectiveness of thermal radiofrequency applied to the musculocutaneous nerve for patients with spasticity.

Evaluate safety and effectiveness of thermal radiofrequency in the musculocutaneous nerve in patients with focal elbow flexor spasticity. Ambispective observational follow-up study. Patients with focal spasticity secondary to central nervous system injury with elbow flexor pattern who received thermal radiofrequency treatment in the musculocutaneous nerve between 2021 and 2023 were included. 12 patients. Ultrasound-guided thermal radiofrequency was applied to the musculocutaneous nerve at 80°C for 90 s. Effectiveness was assessed prior to thermal radiofrequency and at 6 months using scales to measure pain (VAS), spasticity (MAS), disability (DAS), quality of life (SQol-6D), patient-perceived and physician-perceived satisfaction (PIG-C, PGA), and goal attainment (GAS). Elbow joint range of motion was evaluated via goniometry. Safety was evaluated by assessing side effects. Patients had statistically significant improvements in spasticity (p = 0.003), severe elbow flexion (p = 0.02), pain (p = 0.046), functioning (p < 0.05), and spasticity-related quality of life (p < 0.05 in three sections). Furthermore, treatment goals were attained. Patient- and physician-perceived clinical improvement was achieved. Regarding side effects, two patients had dysesthesia that was self-limiting, with maximum duration of 1 month. Thermal radiofrequency in the musculocutaneous nerve can be a safe, effective treatment for patients with severe spasticity with an elbow flexor pattern.

Effects of the COVID-19 Pandemic on Hand and Arm Dysfunction: A Google Trends Analysis.

Introduction The COVID-19 pandemic prompted individuals to make a number of lifestyle alterations. Few studies have examined the development of any hand and/or arm dysfunctions that may have resulted. The purpose of this study was to identify hand and/or arm overuse injuries that may have occurred as a result of the stay-at-home orders during the COVID-19 pandemic. Methods A Google Trends analysis of the terms "hand pain," "carpal tunnel syndrome," "cubital tunnel syndrome," "trigger finger," "de Quervain tenosynovitis," "elbow pain," "tennis elbow," "golfer's elbow," "thumb base arthritis," and "extensor carpi ulnaris tenosynovitis" in the United States, United Kingdom, Canada, and India was performed from June 2019 to January 2023. The noted timeframe was divided into quarters of 47 weeks, with the first quarter (June 2, 2019, through April 19, 2020) serving as a pre-pandemic baseline. The analysis compared initial results noted in the first quarter to individual results from the second, third, and fourth quarters. Results The most notable findings were the upward trends of the terms "hand pain," "carpal tunnel," and "trigger finger."Specifically, India showed a significant increase in the terms "hand pain" and "carpal tunnel syndrome" in the second, third, and fourth quarters. The United States additionally showed a significant upward trend in the terms "carpal tunnel syndrome" and "trigger finger" in the second, third, and fourth quarters. The United Kingdom also reported a significant upward trend in the term "trigger finger" in the second, third, and fourth quarters. Conclusion Numerous factors likely contributed to the increased interest in these terms, such as the increase in telework and associated mobile device usage due to lockdown during the COVID-19 pandemic. Movements associated with performing these tasks may have led to an increased prevalence of hand pain, thus prompting increased queries of these terms through an online search engine.

Bilateral Radial Head and Neck Nondisplaced Fracture, a Challenge for Treatment: A Case Report

Background: Radial head and neck fractures are one of the common fractures of the elbow in adult patients. There are controversies in the treatment of nondisplaced head and neck fractures. However, nonoperative treatment remains a treatment choice for nondisplaced radial head fracture without motion block. Case Report: We presented a 23-year-old patient who had a bilateral nondisplaced radial head fracture. The patient was managed with conservative treatment and early elbow range of motion (ROM). Finally, the patient had a full ROM without pain in both elbows. Conclusion: Conservative management with early mobilization remains an effective approach for treating bilateral nondisplaced radial head fracture, yielding satisfactory outcomes.

Update on elbow arthroplasties with emphasis on imaging

Elbow arthroplasty is increasing in popularity and can be used to treat many conditions, such as trauma, primary and secondary osteoarthritis, inflammatory arthritis, and osteonecrosis. Total elbow arthroplasty (TEA) is reserved for patients with severe symptoms refractory to more conservative management. In addition to TEA, hemi-arthroplasty, interposition arthroplasty, and resection arthroplasty also play roles in the management of elbow pain. There are specific indications for each type of arthroplasty. Postoperative complications may occur with elbow arthroplasties and may be surgery or hardware related. Imaging is important in both pre-operative planning as well as in post-surgical follow-up. This article reviews the different types of elbow arthroplasties, their indications, their normal postoperative imaging appearances, and imaging findings of potential complications.

Cubital Tunnel Syndrome Due to Intraneural Ganglion Cysts of the Ulnar Nerve With Joint-Cyst Connection at the Elbow

BACKGROUND AND OBJECTIVES: The unifying articular theory suggests that intraneural ganglion cysts in the cubital tunnel arise from the elbow joint and are connected to the ulnar nerve through an articular branch. This study aimed to report our clinical experience with these cysts and our surgical findings and outcomes. METHODS: We retrospectively analyzed 13 patients who underwent surgery for cubital tunnel syndrome caused by an intraneural ganglion cyst of the ulnar nerve. Clinical symptoms, physical examination findings, nerve conduction testing electromyography, plain radiography, and ultrasonography were evaluated before and after surgery. MRI was performed in 2 patients. Cyst decompression, disconnection of the articular branch, and ulnar nerve transposition were performed in all. RESULTS: The mean follow-up was 29 months. After surgery, local elbow pain and Tinel sign disappeared in all patients, and the average Numerical Rating Scale dropped from 3.7 (2-5) to 0 (0-0). Two-point discrimination testing was normal (&lt;5.0 mm) in 12 patients. Wartenberg sign and “claw hand” deformity became negative, and muscle function and motor nerve conduction velocity were improved in 12 patients. The Medical Research Council muscle strength grade was M4 or M5 in the flexor carpi ulnaris, flexor digitorum profundus of the 4th and 5th digits, and first dorsal interosseous muscle in 12 patients. Postoperative spontaneous potentials including fibrillation and sharp waves, and motor unit recruitment in the first dorsal interosseous muscle were obviously improved. A cystic articular branch was confirmed during surgery in all patients. No cyst recurred clinically or on follow-up ultrasonography. CONCLUSION: The unifying articular theory of intraneural ganglion cysts applies to those located in the ulnar nerve at the elbow. Surgical disconnection of the articular nerve branch from the ulnar nerve eliminated the pathway for cyst recurrence and achieved good long-term outcomes.

Denervation procedure of the lateral epicondyle for refractory lateral epicondylitis

BackgroundLateral epicondylitis is the most common cause of lateral elbow pain in adults, and non-operative treatment is the first-line management modality of choice. Pain refractory to conservative management may improve with surgical interventions involving ECRB débridement or denervation. This investigation was conducted to evaluate the long-term analgesic efficacy, incidence of postoperative sensory deficits, and postoperative elbow functionality in patients who underwent a denervation surgery of the posterior branch of the posterior cutaneous nerve of the forearm (PBPCNF) for refractory lateral epicondylitis. MethodsThis investigation was an IRB-approved, single-center, single-surgeon case series of 22 patients who underwent denervation surgery with an average final follow-up of 4.7 years. Inclusion criteria for surgery were a minimum of 6 months symptom duration refractory to conservative therapies, a minimum of 2 years clinical follow-up, and significant (70-80%) pain relief from the nerve block test. Visual Analog Scale (VAS) pain and Single Assessment Numerical Evaluation (SANE) scores were used to assess pain and function, respectively. The incidence of postoperative sensory deficits was evaluated via clinical exam. ResultsCompared to the preoperative average, the cohort’s mean VAS pain was significantly decreased at all postoperative follow-up intervals, including 2 weeks, 1 year, and final average follow-up of 4.7 years. At the final follow-up, the mean SANE score was 98.8 ± 2.6, and one patient (4.5%), who reported the same sensory deficit preoperatively, reported postoperative sensory deficits. ConclusionsThe PBPCNF denervation procedure is a highly efficacious procedure for achieving long-term pain control in the treatment of refractory lateral epicondylitis. The PBPCNF denervation procedure affords patients a high level of postoperative functionality with a low incidence of sensory deficits.
