Abstract
The pathophysiology of lateral epicondylitis (LE) remains not fully elucidated, as it involves a complex interaction of anatomical structures. The primary objective of the research is to identify a potential relationship between LE and the ulnohumeral angle (UHA), which demonstrates the coronal alignment of the elbow. Patients diagnosed with LE between September 1st, 2020, and September 1st, 2023, were retrospectively examined. Demographic information and UHA measurements of patients meeting the inclusion criteria and a control group with similar criteria were collected. Measurements were independently conducted by 2 orthopedists at a 2-week interval and compared. Among 413 patients meeting the inclusion criteria and the control group comprising 420 patients, there were no significant differences in age, gender, and side (P = .447, P = .288, P = .159, respectively). The mean UHA for the LE group was 13.49 ± 4.24, while for the control group, it was 12.82 ± 9.19, showing a significant difference (P = .026). The inter-observer and intraobserver reliability of the angle measurements were both above 0.80. We hypothesize that the increase in UHA in patients with LE reflects an adaptive change secondary to compressive forces acting on the lateral aspect of the elbow. This study is the first to describe the relationship between LE and UHA based on anatomical-biomechanical foundations, suggesting a cause-and-effect relationship. Further studies are warranted to delve deeper into this relationship.

Abstract
OBJECTIVE Post-traumatic posterolateral rotatory instability (PLRI) can be shown as radiocapitellar incongruity or posterior translation (PT) of the radial head in magnetic resonance imaging (MRI). We aimed to evaluate whether PT correlated with pathologic changes of lateral elbow stabilizers in patients with lateral epicondylitis. MATERIALS AND METHODS In MRIs of 160 patients with lateral epicondylitis, we measured PT of the radial head in the sagittal images. We qualitatively graded five lesions of the lateral elbow structures that included common extensor tendon (CET) lesion (grade 1-3), lateral collateral ligament complex (LCLC) insufficiency (grade 0-2), and absence or presence of bone marrow signal change, osteochondral lesion, and calcification. We analyzed whether the PT correlated with pathologic changes of the lateral elbow stabilizers and evaluated the diagnostic value of the PT for severe lesions. RESULTS The average PT was 1.9 mm. The PT correlated with both the CET lesion (p < 0.001) and LCLC insufficiency (p < 0.001). The optimal cutoff values of the PT for grade 3 CET lesion and grade 2 LCLC lesion were 2.6 and 2.8 mm, respectively. When potential PLRI was defined as the PT of > 3.4mm as suggested for post-traumatic PLRI, 21 patients had potential PLRI. The positive predictive values of the PT > 3.4mm were 76% for grade 3 CET lesions and 67% for grade 2 LCLC insufficiency. CONCLUSION This study demonstrates that PT of the radial head correlates with pathological changes of the lateral elbow stabilizers. As radiocapitellar incongruity is easy to measure quantitatively, it can be used for screening potential PLRI in patients with lateral epicondylitis.

Abstract
PURPOSE Lateral epicondylitis is generally considered an extra-articular condition. The role of minor instability in the aetiology of lateral elbow pain has rarely been considered. The aim of this study was to evaluate the correlation of lateral ligamentous laxity with aspects of intra-articular lateral elbow pathology and investigate the role of minor instability in lateral elbow pain. METHODS Thirty-five consecutive patients aged between 20 and 60 years with recalcitrant lateral epicondylitis who had failed conservative therapy and had no previous trauma or overt instability, were included. The presence of three signs of lateral ligamentous patholaxity and five intra-articular findings were documented during arthroscopy. The relative incidence of each of these was calculated, and the correlation between patholaxity and intra-articular pathology was evaluated. RESULTS At least one sign of lateral ligamentous laxity was observed in 48.6% of the studied cohort, and 85.7% demonstrated at least one intra-articular abnormal finding. Radial head ballottement was the most common sign of patholaxity (42.9%). Synovitis was the most common intra-articular aspect of pathology (77.1%), followed by lateral capitellar chondropathy (40.0%). A significant correlation was found between the presence of lateral ligamentous patholaxity signs and capitellar chondropathy (p = 0.0409), as well as anteromedial synovitis (p = 0.0408). CONCLUSIONS Almost one half of patients suffering from recalcitrant lateral epicondylitis display signs of lateral ligamentous patholaxity, and over 85% demonstrate at least one intra-articular abnormality. The most frequent intra-articular findings are synovitis and lateral capitellar chondropathy, which correlate significantly with the presence of lateral ligamentous patholaxity. The fact that several patients demonstrated multiple intra-articular findings in relation to laxity provides support to a sequence of pathologic changes that may result from a symptomatic minor instability of the lateral elbow (SMILE) condition.

Abstract
The aim of the study is to determine the inter-reliability and intra-observer reliability of magnetic resonance imaging (MRI) for lateral epicondylitis and investigate whether there is a potential relationship between MRI abnormalities of the common extensor tendon (CET) and its clinical symptom.The study group comprised 96 consecutive patients (46 men and 50 women) with a clinical diagnosis of chronic lateral epicondylitis, which were examined on 3.0 T MR. An MRI scoring system was used to grade the degree of tendinopahty. Three independent musculoskeletal radiologists, who were blinded to the patients' clinical information, scored images separately. Clinical symptoms were assessed using the Patient-Rated Tennis Elbow Evaluation (PRTEE).Of all the patients, total 96 elbows had MRI-assessed tendinopathy, including 38 (39.6%) with grade 1, 31 (32.3%) with grade 2, and 27 (28.1%) with grade 3. Inter-observer reliability and intra-observer agreement for MRI interpretation of the grades of tendinopathy was good, and a positive correlation between the grades of tendinopathy and PRTEE was determined.MRI is a reliable tool in determining radiological severity of chronical lateral epicondylitis. The severity of MR signal changes positively correlate with the patient's clinical symptom.

Abstract
PURPOSE We investigated the general, sensory, and sympathetic innervation patterns at the undersurface of the extensor carpi radialis brevis (ECRB) origin in patients with recalcitrant tennis elbow. METHODS Eight elbows in eight consecutive patients (6 females and 2 males) with tennis elbow who underwent arthroscopic surgery were included in this study. The mean age was 45 years (38-66 years), and the mean duration of symptoms before surgery was 23 months (13-52 months). Operative treatment consisted of an arthroscopic inspection and debridement of the ECRB origin. Control tissues were obtained from biopsy of the ECRB capsule in two patients with osteochondritis dissecance of the capitellum who underwent arthroscopic resection of loose bodies. The tissue specimens were investigated immunohistochemically with antibodies delineating general (PGP9.5), sensory (SP/CGRP), and sympathetic (NPY) nerve patterns. RESULTS In the non-tendinosis control tissue, SP/CGRP and NPY immunoreactions were heterogeneously distributed in association with blood vessels. Pathologic evaluation of the biopsy tissue showed atypical fibrous granulation containing numerous vessels and nerve structures in all eight patients. Marked reactions to PGP 9.5 took the form of nerve fibers associated with arteries and arterioles in the atypical granulation. Most of the perivascular innervation was found to express NPY. The immunoreactions for SP and CGRP were invariably weak. CONCLUSION Increased perivascular sympathetic innervation accompanied with loss of sensory innervation at the undersurface of the ECRB tendon may play a role in chronic pain generation in recalcitrant tennis elbow.

Abstract
OBJECTIVES The purpose of this study was to define in volunteers and cadavers the positions of structures at risk and the extensor carpi radialis brevis (ECRB) origin limits for sonographically guided percutaneous tendon release in tennis elbow. METHODS First, in volunteers, we used Doppler sonography to determine the position (danger zone) of the structures at risk (neurovascular bundle and radial collateral ligament) from the most lateral point of the epicondyle (point of entry). Second, in cadavers, we studied the footprint of the ECRB's origin for finally performing sonographically guided tendon release (1- to 2-mm incision) away from the danger zone. Efficacy was measured in terms of detachment ratios for the ECRB and safety as the absence of neurovascular bundle or radial collateral ligament injuries. RESULTS In 10 volunteers (20 elbows), the neurovascular bundle was located 18.1 mm or greater anteromedially from the point of entry. The neurovascular bundle was not in direct contact with the bone. In 13 formaldehyde-embalmed cadaver elbows, the distance between the origin of the ECRB and the radial collateral ligament was 0 mm or greater. The anterior origin of the ECRB did not contact the neurovascular bundle. The maximum attachment limits of the ECRB were at 15, 5, 15, and 16 mm from the point of entry (anterior, posterior, proximal, and distal margins, respectively). Average detachment ratios were excellent for anterior and distal margins and good for posterior and proximal margins, without neurovascular bundle or radial collateral ligament injuries. CONCLUSIONS This study determined a danger zone to avoid and an area of probability in which to enclose most of the ECRB's origin for sonographically guided percutaneous tendon release. A 360° ECRB detachment can be performed safely and effectively. Clinically, sonographically guided percutaneous tendon release should selectively target pathologic regions.

Abstract
Epicondilites are pathologies poorly understood from the aetiopathogenetic point of view. In this regard, many hypotheses have been considered and numerous anatomical structures are involved. Current therapeutic options are either conservative or surgical. Conservative treatments are: immobilization of the elbow flexed at 90-degrees, stretching the forearm muscles, manipulating the wrist, the application of low-energy extracorporeal shock waves, acupuncture, autologous blood injection under the extensor carpi radialis brevis, laser therapy and pulsed electromagnetic field therapy. Surgical treatments are: fasciotomy, excision of angiofibroblastic hyperplasias located at the origin of extensor carpi radialis brevis, partial release of the orbicular ligament, release of the extensor muscles, elongation of the tendon of extensor carpi radialis brevis and arthroscopic treatment. Advantages and disadvantages are described for each treatment according to the international literature.

Abstract
OBJECTIVE To describe structural characteristics and sonographic alterations of the common extensor tendon (CET). METHODS In 240 patients, we determined the body mass index; sonographic CET thickness, morphologic characteristics, and alterations; and color Doppler measurements of the epicondylar artery width and peak systolic velocity. Age, sex, epicondylalgia history, activities (work, sports, and hobbies), and dominant and nondominant elbows were noted. RESULTS The CET was thicker in the dominant elbow (4.77 versus 4.61 mm [P = .023]), male patients (dominant, 5.09 versus 4.46 mm [P < .001]; nondominant, 5.00 versus 4.21 mm [P < .001]), patients involved in risk activities (dominant, 5.21 versus 4.70 mm [P < .001]; nondominant, 5.12 versus 4.53 mm [P < .001]), and those with a history of epicondylalgia (right, 5.27 versus 4.70 mm [P < .001]; left, 4.86 versus 4.60 mm [P = .316]). Thickness correlated weakly with age (dominant, r = 0.284; nondominant, r = 0.215) and moderately with weight (dominant, r = 0.492; nondominant, r = 0.502). The mean epicondylar artery diameter was 1.35 mm (SD, 0.96 mm); mean peak velocity, 13.01 cm/s (SD, 4.90 cm/s). Morphologic abnormalities were found in 79.5% of patients with a history of epicondylalgia; 7.7% with no history had abnormalities; and 55.9% with abnormalities but no history were older than 55 years. Bone spurs (49.2% versus 16.4% [P < .001]), tendon calcifications (21.5% versus 3.9% [P < .001]), and bone cortex abnormalities (12.3% versus 1.7% [P < .001]) were found more often in non-normal elbows; 79.4% of bone spurs in normal elbows occurred in patients older than 55 years. CONCLUSIONS Mild sonographic alterations in the CET and bone spurs should be considered with caution when assessing epicondylar pain, especially in patients older than 55 years and those with a history of epicondylalgia.

Abstract
All cases of lateral epicondylitis surgically treated in Dr. Pruzansky's office practice between October 1986 and December 2005 yielded 24 elbows for this study. Patients were treated with surgical débridement and direct repair to bone through bone tunnels (18 elbows), repair with suture anchors (3 elbows), or augmentation with autologous tendon graft and reattachment to bone via suture anchors (3 elbows). This series represents the earliest reattachment cases to be reported, and with the longest follow-up. Mean follow-up (both telephone and office interviews) was 64.7 months. All patients reported satisfaction and graded their outcomes as good or excellent. Mean time to full painless preinjury level of use of the elbow was 4.3 months for patients who underwent simple repair and 2.75 months for patients repaired with a graft. Surgical reattachment of the débrided extensor tendon of origin of the elbow to bone, either directly or with autologous tendon graft, provided pain relief and return to preinjury level of function in a predictable manner. Both primary repair and tendon graft procedures can be used in primary and salvage surgeries in tennis elbow cases in which conservative treatment fails.

Abstract
The aim of our study is to document the arthroscopic findings in resistant lateral elbow pain. We have reviewed the findings in a consecutive series of 117 elbow arthroscopies performed on patients with lateral elbow pain resistant to conservative treatment. We found established degenerative changes involving articular cartilage in 68 patients (59%). In 60 of these 68 patients (88%) the degenerative changes were confined to the lateral compartment and contrasted with a normal appearance of the articular cartilage of the medial compartment. Primary lateral compartment arthritis is more common than previously thought, it mostly affects a young population and could easily be misdiagnosed as lateral epicondylitis.

Abstract
Lateral epicondylitis is a painful and functionally limiting entity affecting the upper extremity and is frequently treated by hand surgeons. The anatomic basis of the injury to the extensor carpi radialis brevis origin appears to be multifaceted, involving hypovascular zones, eccentric tendon stresses, and a microscopic degenerative response. Although many treatments have been advocated, there is little clear consensus on which modality works best, for both conservative and operative options. In this article, we present an overview of this difficult problem and an evidence-based review of treatment choices.

Abstract
OBJECTIVE Referred pain and pain characteristics evoked from the extensor carpi radialis brevis, extensor carpi radialis longus, extensor digitorum communis, and brachioradialis muscles was investigated in 20 patients with lateral epicondylalgia (LE) and 20-matched controls. METHODS Both groups were examined for the presence of myofascial trigger points (TrPs) in a blinded fashion. The quality and location of the evoked referred pain, and the pressure pain threshold (PPT) at the lateral epicondyle on the right upper extremity (symptomatic side in patients, and dominant-side on controls) were recorded. Several lateral elbow pain parameters were also evaluated. RESULTS Within the patient group, the elicited referred pain by manual exploration of 13 out of 20 (65%) extensor carpi radialis brevis muscles, 12/20 (70%) extensor carpi radialis longus muscles, 10/20 (50%) brachioradialis muscles, and 5/20 (25%) extensor digitorum communis muscles, shares similar pain patterns as their habitual lateral elbow and forearm pain. The mean number of muscles with TrPs for each patient was 2.9 [95% confidence interval (CI) 1,4] of which 2 (95% CI 1,3) were active, and 0.9 (95% CI 0,2) were latent TrPs. Control participants only had latent TrPs (mean: 0.4; 95% CI 0,2). TrP occurrence between the 2 groups was significantly different for active TrPs (P<0.001), but not for latent TrPs (P>0.05). The referred pain pattern was larger in patients than in controls, with pain referral to the lateral epicondyle (proximally) and to the dorso-lateral aspect of the forearm in the patients, and confined to the dorso-lateral aspect of the forearm in the controls. Patients with LE showed a significant (P<0.001) lower PPT (mean: 2.1 kg/cm; 95% CI 0.8, 4 kg/cm) as compared with controls (mean: 4.5 kg/cm; 95% CI 3, 7 kg/cm). Within the patient group, PPT at the lateral epicondyle was negatively correlated with both the total number of TrPs (rs=-0.63; P=0.003) and the number of active TrPs (rs=-0.5; P=0.02): the greater the number of active TrPs, the lower the PPT at the lateral epicondyle. DISCUSSION Our results suggest that in patients with LE, the evoked referred pain and its sensory characteristics shared similar patterns as their habitual elbow and forearm pain, consistent with active TrPs. Lower PPT and larger referred pain patterns suggest that peripheral and central sensitization exists in LE.

Abstract
Elbow injuries constitute a sizeable percentage of tennis injuries. A basic understanding of biomechanics of tennis and analysis of the forces, loads and motions of the elbow during tennis will improve the understanding of the pathophysiology of these injuries. All different strokes in tennis have a different repetitive biomechanical nature that can result in tennis-related injuries. In this article, a biomechanically-based evaluation of tennis strokes is presented. This overview includes all tennis-related pathologies of the elbow joint, whereby the possible relation of biomechanics to pathology is analysed, followed by treatment recommendations.

Shock waves, as applied in urology and gastroenterology, were introduced in the middle of the last decade in Germany to treat different pathologies of the musculoskeletal system, including epicondylitis of the elbow, plantar fasciitis, and calcifying and noncalcifying tendinitis of the rotator cuff. With the noninvasive nature of these waves and their seemingly low complication rate, extracorporeal shock wave therapy (ESWT) seemed a promising alternative to the established conservative and surgical options in the treatment of patients with chronically painful conditions. However, the apparent advantages of the method led to a rapid diffusion and even inflationary use of ESWT; prospective, randomized studies on the mechanisms and effects of shock waves on musculoskeletal tissues were urgently needed to define more accurate indications and optimize therapeutic outcome. This review covers recent international research in the field and presents actual indications and results in therapy of musculoskeletal conditions with ESWT.

Abstract
Lateral epicondylitis is one of the most common upper extremity pain syndromes. We report the results of patients in whom conservative treatment was unsuccessful and who were finally treated arthroscopically for symptomatic plicae. Ten patients (mean age, 40 years [range, 18-60 years]) who were misdiagnosed as having lateral epicondylitis were included in this study. Examination revealed the site of maximal tenderness to be posterior to the lateral epicondyle and centered at the posterior radiocapitellar joint. Preoperatively, all patients received conservative treatment (physical therapy or corticosteroid injections [or both]). The mean follow-up was 25 months (range, 6-68 months). The mean score on the Disabilities of the Arm, Shoulder and Hand questionnaire was 9 (range, 0-37). Preoperatively, 7 patients had full elbow range of motion; however, in 3 patients, there was a loss of extension at the elbow ranging from 7 degrees to 20 degrees preoperatively. The range of elbow motion was full in all patients postoperatively. No patient demonstrated posterolateral pain after the operation. Synovial plicae of the elbow may be the cause of lateral elbow pain in patients with vague clinical symptoms. Arthroscopic management may provide a successful treatment option for such patients.

Abstract
Clinical and cadaveric studies were done to investigate the role of a degenerative fringe of the radiocapitellar complex subluxating in the radiocapitellar joint in patients with lateral epicondylitis. In the clinical study, arthroscopic resection of this capsular complex was done. Thirty patients with recalcitrant symptoms of lateral epicondylitis for a minimum of 9 months had surgery. In all patients at arthroscopy, a collar-like band of radiocapitellar capsular complex was found to impinge on the radial head and subluxate into the radiocapitellar joint with manipulation under direct vision. Histologic analyses of the resected tissue showed hyaline degeneration and fibrosis. There were no complications in this series. Twenty-eight patients had complete relief of symptoms by this procedure within 2 weeks of surgery. The average time until return to work was 7 days. Elbow arthroscopy was done in 34 cadaveric elbows to examine the relationship of the annular ligament, the lateral joint capsule, and the radial head. A degenerative capsular fold impinging on the radial head was seen in 15 elbows. A classification system, based on the relationship of the capsular fold to the radial head is described. In Type 1 (19 elbows), the radial head is completely exposed. In Type 2 (six elbows), there is partial coverage of the radial head by the capsuloligamentous complex without interposition into the joint in any position. In Type 3 elbows (six elbows), there is subluxation of the capsular edge into the joint, whereas in Type 4 elbows (three elbows), the radial head is completely obscured throughout the range of motion. The lesion was equally prevalent in men and women. The arthroscopic findings at the time of surgery in the clinical group were the same as the Grade 2 and Grade 3 changes that were seen in cadaveric specimens.

Abstract
Treatment of tennis elbow is a problem. We performed magnetic resonance imaging (MRI) examinations of 11 elbows in 11 patients who were referred to us with refractory tennis elbow. Of the 11 elbows, 6 showed a high signal intensity focus on MRI T2 images in the tendon of the extensor carpi radialis brevis at the lateral epicondyle. The other 5 elbows showed various abnormal findings on MRI. The mean age of the 6 patients with a high T2 signal focus was 52.0 years, and the mean morbidity period was 25 months. We performed enucleation of the granulation focus through a surgical approach without detachment of the tendon origin of the extensor carpi radialis brevis. Pain was relieved and elbow function recovered in all 6 cases. This study demonstrates that MRI is an important decision-making tool in the surgical treatment of this condition. Enucleation of the granulation focus with high T2 signal has proved to be effective in 6 selected cases.

Abstract
Epicondylitis and de Quervain's tenosynovitis are two common diagnoses seen by hand therapists in clinical practice. Traditionally, these conditions have been viewed as being due to an inflammatory process and treated as such. New research shows that tendons exhibit areas of degeneration and a distinct lack of inflammatory cells. Tendinosis is degeneration of the collagen tissue due to aging, microtrauma, or vascular compromise. This article reviews key literature related to tendinopathies in the lower extremity and comments on the dearth of similar articles for the elbow and forearm. Hand therapists are encouraged to embrace this new terminology and to engage in research in this difficult area to improve treatment regimens and outcome measures.

Abstract
OBJECTIVES We evaluated the clinical and subjective functional results of open surgical treatment in patients with chronic refractory lateral epicondylitis. METHODS Eleven patients (7 females, 4 males; mean age 42 years, range 29 to 56 years) underwent open surgical treatment for chronic refractory lateral epicondylitis. All the patients had received conservative treatment for at least a year without favorable response. Surgical procedure included release of the lateral extensor origin, excision of the degenerative tissue, decortication or drilling of the anterior lateral condyle, and repair of the extensor tendons. The results were evaluated according to the criteria proposed by Verhaar et al. The mean follow-up was 29 months (range 18 to 45 months). RESULTS The results were excellent or good in 10 patients (90.9%) and acceptable in one patient (9.1%). The mean time to return to work was two months. Nine patients were free of pain in the forearm in the postoperative third month. No wound-related complications were encountered. On subjective evaluations, 10 patients reported full satisfaction, and one patient reported partial satisfaction with the result of the treatment. CONCLUSION Open surgical procedure including release of the origins of the common extensor tendons and excision of the degenerative tissue yields favorable results in the treatment of patients with chronic refractory lateral epicondylitis.

Abstract
OBJECTIVES To improve the understanding of epicondylitis by describing the normal structure and composition of the entheses associated with the medial and lateral epicondyles and their histopathology in elderly cadavers. METHODS Medial and lateral epicondyles were obtained from 12 cadavers. Six middle aged cadavers (mean 47 years) were used to assess the molecular composition of "normal" entheses from people within an age range vulnerable to epicondylitis. Cryosections of epicondylar entheses were immunolabelled with monoclonal antibodies against molecules associated with fibrocartilage and related tissues. A further six elderly cadavers (mean 84 years) were used for histology to assess features of entheses related to increasing age. RESULTS Tendon entheses on both epicondyles fused with those of the collateral ligaments and formed a more extensive structure than hitherto appreciated. Fibrocartilage (which labelled for type II collagen and aggrecan) was a constant feature of all entheses. Entheses from elderly subjects showed extensive microscopic damage, hitherto regarded as a hallmark of epicondylitis. CONCLUSIONS Fibrocartilage is a normal feature and not always a sign of enthesopathy. Furthermore, pathological changes documented in patients with epicondylitis may also be seen in elderly people. The fusion of the common extensor and flexor tendon entheses with those of the collateral ligaments suggests that the latter may be implicated as well. This may explain why pain and tenderness in epicondylitis may extend locally beyond the tendon enthesis and why some patients are refractory to local treatments.

Abstract
A variation of the extensor carpi radialis brevis muscle (ECRB) origin was discovered during a cadaveric dissection. The identified ECRB originated from the fascia/tendon of the extensor digitorum communis (EDC), without any of its origin at the usual location on the lateral epicondyle. The ECRB tendon inserted onto the third metacarpal base. A branch of the posterior interosseous nerve innervated the ERCB. This is the first report of an ECRB originating from the EDC fascia/tendon. This unique variation of the ECRB origin may be of clinical interest, especially in the treatment of lateral epicondylitis (tennis elbow).

Abstract
There is no information on the sensory innervation at the flexor muscle origin at the medial epicondyle of the humerus and it is not known if substance P receptors (Neurokinin 1-receptors, NK1-R) are present in tendon insertions in general. In the present investigation, we have studied the muscle origin in patients suffering from medial epicondylalgia and tennis elbow. Immunohistochemistry and antibodies to substance P (SP) and CGRP as well as the general nerve marker PGP 9.5 were used. Specific immunoreactions were observed in nerve bundles and as free nerve fibers. The immunoreactive structures were partly seen in association with some of the blood vessels. The observations constitute a morphological correlate for the occurrence of nerve mediated effects in this region. By using immunohistochemistry and antibodies to NK1-R, the distribution of this receptor was studied at the insertion of the proximal tendon of the extensor carpi radialis brevis muscle at the lateral epicondyle. Specific immunoreactions were seen as varicose fibers occurring as single fibers or grouped into bundles, indicating that SP has effects in the nerves in this region. The results give further evidence for a possible neurogenic involvement in the pathophysiology of tennis elbow and in medial epicondylalgia.

Abstract
Tennis elbow tendinosis (epicondylitis) is most commonly caused by tendon overuse and failed tendon healing. The pathoanatomy of overuse tendinopathy is noninflammatory "angiofibroblastic tendinosis." The specific areas of elbow abnormality include the extensor carpi radialis brevis-extensor digitorum communis complex laterally, the pronator teres, flexor carpi radialis medially, and triceps posteriorly. The primary goal of nonsurgical treatment is to revitalize the unhealthy tissue that produces pain. Successful nonsurgical treatment comprises rehabilitative resistance exercise and progression of the exercise program. If rehabilitation fails, surgical treatment can be quite successful.

Abstract
The guidelines of the German Orthopaedic Societies regarding the treatment of lateral elbow epicondylitis were analysed on the ground of recently published reviews or randomised placebo-controlled trials (RCT). For the acute phase, reviews or RCTs failed to show a clinical effect beyond placebo if follow-up was extended over 6 weeks. For the chronic phase a current Cochrane review failed to identify any controlled trial regarding surgical procedures during the last decades. Without an adequate control group, it is not possible to draw any meaningful conclusions about the value of this modality of treatment. Therefore surgery is not indicated before repetitive low-energy extracorporeal shock wave therapy (ESWT) has been applied. This novel treatment, under strictly standardized conditions, showed effects beyond placebo in independent randomised placebo-controlled trials for follow-up periods of 3 and 6 months. To date there exists no evidence-based therapeutic algorithm for the treatment of acute and chronic tennis elbow. Even medium-term effects should be regarded as either a placebo effect or natural regression to the mean.

Abstract
OBJECTIVE To identify the salient magnetic resonance imaging (MRI) features of tennis elbow. An objective diagnosis is important when managing work-related incapacity due to ill-defined lateral arm pain. METHOD Twenty-three symptomatic and 17 asymptomatic elbows in 20 patients with tennis elbow, no evidence of other pathology and no previous treatment were imaged using established MRI sequences. RESULTS In the symptomatic elbows, the common extensor origin (CEO) showed signs of oedema in 23, thickening in 19, peri-tendon oedema in 3 and tears in 13 cases. More extensive abnormalities were demonstrated in only two elbows. Six out of 17 asymptomatic elbows also showed oedema in the CEO. CONCLUSIONS The CEO is confirmed as the primary site of MRI changes in tennis elbow. Oedema was commonly found in asymptomatic elbows, necessitating the presence of thickening or tears in the CEO tendon to objectively diagnose tennis elbow on MRI.

Abstract
This study examines the intra-articular anatomy and safe zones for arthroscopic resection of the common extensor origin for the treatment of lateral epicondylitis. The extensor complex was arthroscopically debrided in 7 cadaveric elbows to determine the percentage of each tendinous origin that was resectable. Elbow stability was assessed, and safe zones of resection were determined. The extensor carpi radialis brevis and extensor digitorum communis origin was resected a mean of 100% and 90%, respectively. Elbow stability was maintained when resection did not extend posteriorly to an intra-articular line bisecting the radial head. Posterolateral rotatory instability occurred when debridement was continued posteriorly to the axis of the radial head. In conclusion, complete resection of the extensor carpi radialis brevis-extensor digitorum communis common origin is achievable via standard arthroscopic techniques. The lateral ulnar collateral ligament remains intact and elbow stability is maintained when debridement of the extensor origin does not extend posteriorly to a line bisecting the radial head.

Abstract
OBJECTIVES We evaluated the results and advantages of percutaneous extensor tenotomy performed in patients with lateral epicondylitis resistant to conservative treatment. METHODS Percutaneous extensor tenotomy was performed in nine patients (7 females, 2 males; mean age 44 years; range 32 to 54 years) with lateral epicondylitis unresponsive to conservative treatment. The mean duration of the complaints was 25 months (range 9 months to 4 years), during which a mean of 2.7 (range 2 to 4) local corticosteroid injections was administered. The patients were operated under local anesthesia in an outpatient setting. The procedure lasted approximately 4.5 minutes. The remaining portion of the tendon was removed by manipulation. The results were evaluated according to the criteria by Verhaar et al. The mean follow-up period was nine months (range 4 to 15 months). RESULTS The patients were able to use their affected arms after a mean of nine days (range 6 to 14 days). Hematoma that developed in the lateral epicondyle distally in two patients resolved spontaneously. All patients' complaints of pain decreased by more than 50% within six to eight weeks. The results were excellent or good in eight patients and fair in one patient. All patients but one were satisfied with the result of tenotomy. CONCLUSION Percutaneous extensor tenotomy is a simple procedure; it can be performed under outpatient settings, and yields favorable results in patients with lateral epicondylitis resistant to conservative treatment.

Abstract
Insertion tissue biopsies of right arm common extensor tendons from 11 patients with chronic lateral epicondylitis were processed for light and electron microscopy. The subjects were aged between 38 and 54 years (only one was 25). The specimens showed a variety of structural changes such as biochemical and spatial alteration of collagen, hyaline degeneration, loss of tenocytes, fibrocartilage metaplasia, calcifying processes, neovascularization and vessel wall modifications. Tissue alterations were evident in limited zones of the tendon fibrocartilage in which the surgical resection was generally visible. The areas where the degenerative processes were localized, were restricted and in spatial contiguity with morphologically normal ones. The observed cases presented histological and electron microscopic findings that characterize lateral epicondylitis as a degenerative phenomenon involving all tendon components.

Abstract
PURPOSE The aim of this prospective study was to compare the sensitivity and specificity of sonography with those of MRI in evaluating epicondylitis. METHODS The affected elbows of 11 patients with suspected epicondylitis were examined sonographically, and the contralateral (normal) elbow was also examined for comparison. In 10 of these patients, the affected elbow was also examined with MRI. In addition, both elbows of 6 volunteers without epicondylitis were examined sonographically; 1 elbow of each volunteer was designated as the "test" elbow and was examined with MRI. The sonograms of the patients' affected elbows and the volunteers' test elbows were paired with the sonograms of the contralateral elbows for comparison and were randomly shown twice to 2 readers. These readers, working independently and without knowledge of the findings of MRI, were instructed to state whether each elbow was normal or affected by epicondylitis. The MRI scans were then shown to the readers for similar review. RESULTS Sonographic features of epicondylitis included outward bowing of the common tendon, presence of hypoechoic fluid subadjacent to the common tendon, thickening, decreased echogenicity, and ill-defined margins of the common tendon. Sensitivity for detecting epicondylitis ranged from 64% to 82% for sonography and from 90% to 100% for MRI. Specificity ranged from 67% to 100% for sonography and from 83% to 100% for MRI. CONCLUSIONS Sonography is as specific but not as sensitive as MRI for evaluating epicondylitis. Used as an initial imaging tool, sonography might be adequate for diagnosing this condition in many patients, thus allowing MRI to be reserved for patients with symptoms whose sonographic findings are normal.

Abstract
Twenty-two patients (23 limbs) with chronic lateral elbow tendonopathy were examined retrospectively after surgical management. Thirteen men and 9 women with an average age of 43 years (range, 32-54 years) had a mean follow-up time of 41.2 months (range, 9-97 months). All patients underwent at least 6 months of nonsurgical treatment without favorable response. V-Y slide of the common extensor origin was done for all patients. Sixteen patients (17 elbows) were examined after surgery and 6 were interviewed by telephone. None of the patients had major complications or permanent loss of elbow motion. A pain rating scale of 1 to 10 (10 being the worst) showed a difference from a rating of 9.0 (range, 7-10) before surgery to 1.4 (range, 0-4) after surgery. Grip strength increased from 57 lb (range, 5-125 lb) to 99 lb (range, 60-135 lb). Five patients (23%) reported some degree of cold intolerance. Twenty-one patients (95%) returned to their preoperative occupation with 1 patient not returning to work because of elbow pain caused by heavy and repetitive elbow stress especially from vibrating tools. Twenty-one patients (95%) reported no limitations in daily activities; 1 patient reported difficulty with opening jars. Seven people (32%) reported limitations in high-demand recreational activities. All patients were rated as poor before surgery and excellent or good after surgery by a grading scale. All patients were satisfied with the outcome of surgery. After surgical treatment for lateral elbow tendonopathy, pain relief and restoration of elbow function can be achieved. V-Y slide of the extensor origin has low morbidity, does not violate the joint space or lateral stabilizing ligaments of the elbow, allows adequate release, and has a high rate of satisfaction.

Abstract
Today the clinical use of extracorporeal shockwave application (ESWA) for the treatment of lateral tennis elbow is hampered by the lack of results from randomized controlled trials and of predictive parameters of clinical outcome. The present prospective study aimed to provide the latter by means of magnetic resonance imaging (MRI). Twenty-three female and 19 male patients with unilateral chronic tennis elbow of the dominant site were clinically examined before and after repetitive low-energy ESWA. MRI was performed before ESWA to evaluate signal intensity changes or contrast enhancement of the common extensor tendon and the lateral epicondyle. After ESWA (mean follow-up period 18.6 months for all patients), clinical evaluation showed a significantly better mean clinical performance after ESWA than before treatment. Interestingly, male patients showed a significantly better mean clinical performance after ESWA than female patients, and male and female patients differed significantly in the signal intensity of the common extension tendon cross-section and tendon thickening on MRI. For female patients, MRI scans could be applied for predicting a positive clinical outcome of ESWA. This study reports the first indication of predictability of positive clinical outcome of the treatment of chronic lateral tennis elbow by ESWA using imaging prior to treatment. This may serve as an important step towards overcoming the therapeutic nihilism with respect to the non-operative management of this condition recently in the literature.

Abstract
We assessed the clinical utility of 42 arthroscopic releases for lateral epicondylitis in 40 patients (average age, 43 years) with an average of 14 months of symptomatic history before surgery. At arthroscopy, we found 15 type I lesions (intact capsule), 15 type II lesions (linear capsular tear), and 12 type III lesions (complete capsular tear), and associated disorders were found in 69% of the patients. At an average follow-up of 2.8 years, patients were asked to report on elbow pain and function. Subjectively, the patients rated their pain at rest as an average of 0.9 (0 = no pain; 10 = severe pain). They rated their pain with activities of daily living as 1.4 and their pain with sports and work as 1.9. Functionally, they averaged 11.1 of 12 possible points. Of the 39 elbows in the 37 patients who were available for follow-up, 37 were rated "better" or "much better." Patients returned to work in an average of 2.2 weeks. Grip strength averaged 96% of the strength of the unaffected limb. Arthroscopic tennis elbow release is a reliable treatment that allows patients an expedited return to work and may result in greater postsurgical grip strength.

Abstract
We studied the origin of extensor carpi radialis brevis using 40 fresh frozen human cadaver specimens. Ten were stained with haematoxylin and eosin and trichrome which showed the collagenous structure of the extensor tendons at their origin. Gross anatomical observation showed that there was no definitive separation between brevis and communis at the osseotendinous junction. The histological findings confirmed the lack of separation between the two tendons. The extensor tendons were in close proximity to the joint capsule but trichrome staining showed no interdigitation of the tendon with the capsule. The validity of ascribing the pain of lateral epicondylitis to extensor carpi radialis brevis must be questioned. It appears to arise more from the 'common extensor' origin.

Abstract
By using immunohistochemistry and antibodies to a general nerve marker, protein gene product (PGP) 9.5, the overall innervation at the extensor carpi radialis brevis (ECRB) muscle origin was investigated in patients with tennis elbow and in healthy controls. The autonomic innervation was studied by using antibodies to neuropeptide Y (NPY), tyrosine hydroxylase (TH), and vasoactive intestinal peptide (VIP). The sensory innervation was visualized by using antibodies to substance P and calcitonin gene-related peptide. PGP 9.5 immunoreactions were detected in association with small blood vessels and arteries and within nerve bundles. There was, however, heterogeneity in the perivascular nerve fiber distribution since some blood vessels exhibited a high degree of PGP 9.5 innervation and some negligible or no such innervation at all. There was marked TH/NPY innervation in the walls of a subpopulation of the arteries, basically no VIP-containing nerves, and sensory innervation restricted to the small blood vessels. These observations show that the ECRB muscle origin is supplied with heterogeneously distributed sympathetic and sensory innervations and, furthermore, that there appears to be an imbalance between the vasoconstrictor and vasodilator innervations along the vascular tree in this region.

Abstract
The morphology of the extensor carpi radialis brevis (ECRB) muscle was investigated in 20 patients with longstanding lateral epicondylitis. Muscle biopsies were obtained from the proximal or distal portion of the ECRB and analysed by enzyme- and immunohistochemical methods. Morphological abnormalities were significantly more frequent in patients than controls and included moth-eaten fibres, fibre necrosis and signs of muscle fibre regeneration as well as higher percentages of the fast-twitch oxidative (type 2A) fibre type. Changes were equally distributed proximally and distally. It is concluded that these changes, directly or indirectly, may reflect the cumulative effect of mechanical and/or metabolic overload and that decreased muscular performance in patients with lateral epicondylitis may be due to both elbow pain and physical damage to the ECRB muscle.

Abstract
At least 10 different surgical approaches to refractory lateral epicondylitis have been described, including an arthroscopic release of the extensor carpi radialis brevis tendon. The advantages of an arthroscopic approach include an opportunity to examine the joint for associated pathology, no disruption of the extensor mechanism, and a rapid return to premorbid activities with possibly fewer complications. A cadaveric study was performed to determine the safety of this procedure. Ten fresh-frozen cadaveric upper extremities underwent arthroscopic visualization of the extensor tendon and release of the extensor carpi radialis brevis tendon. The specimens were randomized with regard to the use of either a 2.7-mm or a 4.0-mm 30 degree arthroscope through modified medial and lateral portals. Following this, the arthroscope remained in the joint, and the portal, cannula track, and surgical release site were dissected to determine the distance between the cannula and the radial, median, ulnar, lateral antebrachial, and posterior antebrachial nerves, and the brachial artery and the ulnar collateral ligament. No direct lacerations of neurovascular structures were identified; however, the varying course of the lateral and posterior antebrachial nerves place these superficial sensory nerves at risk during portal placement. As in previous reports, the radial nerve was consistently in close proximity to the proximal lateral portal (3 to 10 mm: mean, 5.4 mm). The ulnar collateral ligament was not destabilized. Arthroscopic release of the extensor carpi radialis brevis tendon appears to be a safe, reliable, and reproducible procedure for refractory lateral epicondylitis. Cadaveric dissection confirms these findings.

Abstract
Fragments of insertion tissue from right arm common extensor muscle have been collected from a 25-year patient with chronic lateral epicondylitis. Specimens, processed for light (LM) and electron (EM) microscopy, evidentiated a variety of degenerative alterations, such as focal hyalinosis, lipoidosis, collagen fiber redistribution, calcifications and vascular changes. Evidence of collagen normal function maintenance and turnover have been also observed in tenocytes.

Abstract
Several authors believe that a compression syndrome of the radial nerve or its muscle branches is responsible for the clinical picture of radiohumeral epicondylopathy. Various structural and functional stenoses have been discussed as possible causes. We performed systematic electromyographies (EMGs) on the extensors subdividing from the radial epicondyle and found significant changes (P < 0.05) in 27/51 patients regarding latency, velocity of nerve conduction and rate of polyphasic potentials. Especially affected were the extensor carpi radialis brevis and the extensor digitorum muscle. In order to clarify causal anatomic correlations, we performed a longitudinal and cross-sectional study on a total of 40 arms from cadavers. We found constant variations from the topographic anatomy published in the standard literature which corresponded to the EMG results in the area between the epicondyle and place of entry into the supinator muscle. In addition, we observed a regularly occurring ulnar deviation from the distal part of the extensor carpi radials brevis origin which protrudes over the plane of insertion of the joint extensor tendon aponeurosis and forms in most cases the arcade of Frohse. Because the deep radial branch and its parallel muscular branches cross this part at an obtuse angle, we think that dynamic pressure on a nerve without structural influences is the pathoanatomic result of this heterogeneously interpreted clinical picture.

Abstract
Tennis elbow occurs as a result of repetitive microtrauma to the musculotendinous unit causing inflammatory and degenerative tissue damage. A good understanding of the aetiology and pathoanatomy will aid the clinician in preventing and recognising this condition. Early recognition with a quality rehabilitative programme, and the judicious use of surgical intervention usually results in full recovery and excellent functional outcomes.

Abstract
Anatomical and clinical research has shown that the entire lateral epicondylar region is innervated only by radial nerve branches. Based on these investigations we have developed a surgical procedure for complete denervation which is indicated only in resistant cases of tennis elbow. Only one nerve pathway calls for careful exposure, otherwise denervation is accomplished blindly by disinsertion of certain muscles. The result of this procedure also depends on simultaneous indirect decompression of the posterior interosseous nerve. Excellent or good results were obtained in 90% on average. Results of denervation did not improve by additional direct radial nerve release.

Abstract
PURPOSE To determine the value of magnetic resonance (MR) imaging in the clinical management of chronic refractory lateral epicondylitis. MATERIALS AND METHODS Coronal three-dimensional Fourier transform, multiplanar gradient-recalled-echo, and fat-suppressed sagittal images were obtained in 33 patients. Twenty of these patients underwent surgical débridement and/or primary tendon repair and were included in the correlative study. Surgical and pathologic reports were reviewed to determine the location and gross characteristics of the tissue. RESULTS Findings at MR imaging correlated with the surgical findings of primary degeneration of the extensor carpi radialis brevis (n = 20). Histopathologic examination demonstrated neovascularization, disruption of collagen, and mucoid degeneration without inflammation. CONCLUSION The use of MR imaging in patients with recalcitrant lateral epicondylitis assists in surgical planning. The definition of tendon degeneration and degree of tear, as depicted on MR images, correlate well with surgical and histologic findings.

Abstract
We report two cases of epicondylitis of the elbow occurring after treatment with fluoroquinolone antibiotics. Both patients had intense pain which appeared very shortly after the first dose of the drug and was not relieved by conservative treatment. Ultrasonography revealed extensive inflammatory lesions with pseudonecrotic areas. MRI confirmed the lesions and also showed a subclinical abnormality of the adjoining tendons. The persistent nature of the pain was the indication for surgical release of the extensor mechanism. After operation pain disappeared completely and the patients were able to return to their normal activities. Lesions of the tendo Achillis are a well-known side-effect of treatment with fluoroquinolone. Our two cases show that such lesions may occur elsewhere. They also indicate the need for caution when prescribing these antibiotics to patients at risk of tendon lesions, such as top-level sportsmen or patients on dialysis or steroid treatment.

Abstract
Epicondylitis occurred in two leisure athletes who were taking fluoroquinolones. No similar cases have been reported in the literature. In both cases, pain occurred early after initiating drug therapy. Pain was intense and was not controlled by usual care. Echography demonstrated major inflammatory lesions with pseudo-necrosis. Magnetic resonance imaging confirmed the lesions and gave evidence of infraclinical lesions of the adjacent tendons. Surgical disinsertion of the epicondyles with biopsy was indicated due to the persistent pain. Histological examination revealed unspecific lesions of hyalin degeneration and a few giant cells in one case. Pain disappeared after surgery and the patients were able to return to their work, but neither was able to continue his sports activity. Lesions of the Achilles tendon have been observed in patients taking fluoroquinolone and the two cases reported here confirm the possibility of other localizations. Care must therefore be taken when prescribing these antibiotics in patients at risk (dialysis patients, those on corticosteroids, high-performance athletes).
