Context:

Injuries to the tendons of the elbow occur often in the overhead athlete, creating a pregnant loss of office and dilemma to sports medicine professionals. A detailed review of the anatomy, etiology, and pathophysiology of tendon injury coupled with comprehensive evaluation and treatment information is needed for clinicians to optimally blueprint treatment programs for rehabilitation and prevention.

Evidence Acquisitions:

The PubMed database was searched in January 2012 for English-language articles pertaining to elbow tendon injury.

Results:

Detailed data on tendon pathophysiology was found forth with incidence of elbow injury in overhead athletes. Several prove-based reviews were identified, providing a thorough review of the recommended rehabilitation for elbow tendon injury.

Conclusions:

Humeral epicondylitis is an actress-articular tendon injury that is mutual in athletes subjected to repetitive upper extremity loading. Enquiry is limited on the identification of handling modalities that can reduce pain and restore function to the elbow. Eccentric do has been studied in several investigations and, when coupled with a complete upper extremity strengthening programme, tin produce positive results in patients with elbow tendon injury. Further enquiry is needed in high-level study to delineate optimal treatment methods.

Keywords: humeral epicondylitis, rehabilitation, elbow tendon injury

Tendon injuries to the human being elbow occur frequently, especially in the overhead athlete due to the repetitive loads and forceful muscular activations inherent in throwing, hitting, serving, and spiking.26,63 The most mutual injuries in the athletic elbow include humeral epicondylitis, valgus extension overload, and ulnar collateral ligament injury.21,52 The initial upper extremity evaluation, including baseline radiographs and clinical testing of the entire upper extremity kinetic chain, forms the critical first step in early on recognition and diagnosis of elbow injury and allows for the evolution of a comprehensive rehabilitation to restore function.

Etiology and Pathophysiology of Tendon Injury

One of the nigh common tendon injuries of the elbow is humeral epicondylitis,53,55 referred to as "tennis elbow," "golfer's elbow," and "thrower's elbow" by laypersons and the sports medicine literature. The repetitive overuse is peculiarly axiomatic in the history of many athletic patients with elbow tendon injury. Classic epidemiological enquiry on adult tennis players shows incidences ranging from 35% to 50%.12,32,35,36,38,59 This incidence is actually far greater than in elite-level junior tennis players (11%-12%).81

As early equally 1873, Runge described humeral epicondylitis, or "tennis elbow," as it is more popularly known.62 Cyriax and Cyriax in 1936, listed 26 causes of tennis elbow,14 while an all-encompassing study by Goldie in 1964 reported hypervascularization of the extensor aponeurosis and increased free nerve endings in the subtendinous space.29 Leadbetterforty later described humeral epicondylitis as a degenerative time-dependent process including vascular, chemic, and cellular events that atomic number 82 to a failure of the cell matrix healing response in human tendon. This clarification of tendon injury differs from earlier theories where an inflammatory response was considered a primary factor; hence, the term tendonitis was used, as opposed to the term recommended by Leadbetter40 and Nirschl and Sobel.53

Humeral epicondylitis is an extra-articular tendinous injury characterized by excessive vascular granulation and an impaired healing response in the tendon, "angiofibroblastic hyperplasia."52,51,55 In a thorough histopathological analysis, specimens of injured tendon from areas of chronic overuse did not incorporate large numbers of lymphocytes, macrophages, and neutrophils.38 Instead, tendinosis is a degenerative process characterized by large populations of fibroblasts, disorganized collagen, and vascular hyperplasia.38 It is non articulate why tendinosis is painful, lacks inflammatory cells, and does not mature. The primary tendon in lateral humeral epicondylitis is the extensor carpi radialis brevis.52-53,55 Approximately 1-third of cases involve the tendon of the extensor communis.38 The extensor carpi radialis longus and extensor carpi ulnaris can be involved equally well. The master sites of medial humeral epicondylitis are the flexor carpi radialis, pronator teres, and flexor carpi ulnaris tendons.52-53,55 The incidence of lateral humeral epicondylitis is far greater than that of medial epicondylitis in recreational tennis players and in the leading arm (left arm in a right-handed golfer), while medial humeral epicondylitis is far more common in elite tennis players and throwing athletes due to the powerful loading of the flexor and pronator muscle tendon units during the valgus extension overload inherent in the acceleration phase of those overhead movement patterns.52-53,55 The trailing arm of the golfer (right arm in a right-handed golfer) is more than likely to have medial symptoms than lateral.

Mechanical loading of tendon tissue is anabolic by upregulating collagen cistron expression and increasing synthesis of collagen proteins peaking 24 hours after exercise and remaining elevated for upwards to seventy to 80 hours.33,48 However, exercise also degrades collagen proteins. This results in a net loss of collagen 24 to 36 hours after training, followed by a cyberspace gain in collagen.44 Thus, a restitution time interval between practise bouts is critical for the tissue to adapt and avert a net catabolic state of affairs. The tissue's adaptive factors are linked to tenocytes, extracellular matrix, and nerve receptors.44

Repetitive strain causes tenocytes to produce inflammatory molecules and engenders microrupture of collagen fibrils.78 Increased inflammatory mediators (eg, prostaglandin E2 [PGE2]) are found in tendons later repetitive mechanical loading.78 Intratendinous injections of PGE2 cause intense degenerative changes, and peritendinous injections of PGE1 result in a histological blueprint of tendinopathy.36,70 Today, several studies confirm an inflammatory background in tendinopathy: granulation of capillary vessels and an inflammatory infiltrate of macrophages, mast cells, and B and T lymphocytes.46,66 Inflammatory cells activate a pour of proinflammatory cytokines (eg, interleukin-eighteen, -15, and -6) found in tendinopathy.47

Tendon cells and fibroblasts, subjected to repetitive mechanical stress in combination with proinflammatory cytokines and transforming growth gene β (TGF-β) stimulation tin transform into myofibroblasts.72 Myofibroblasts are important for tendon healing, mayhap for tissue adaptation.72 Later healing is completed and the mechanical stress is released on the myofibroblasts, these cells undergo programmed cell death (apoptosis).72 If this machinery fails, the myofibroblasts will propagate a hyperproliferative process: fibrosis—a prominent feature of tendinopathy.72

Another factor that may crusade fibroblast hyperproliferation is hypoxia.27 This upregulates matrix metalloproteinases, which alters the material properties of tendon.threescore Hypoxia upregulates vascular endothelial growth factor, increasing microvessel ingrowth (angiogenesis), a major finding in tendinopathy.60

Angiogenesis may cause pain since sclerotherapy relieves pain in tendinopathy.54 However, blood vessels per se are non painful, but ingrowth of sensory nerve fibers in tendinopathic patients may be.1,41,66 Salubrious nonpainful tendons are almost aneuronal.1,41 Chronic painful tendons show ingrowth of sensory nerves from the paratenon with release of nociceptive substances.1,41,76 Restricting pathological nervus ingrowth by denervation (eg, mini-invasive surgery or release of the paratenon) can relieve pain.76

Sensory nerve ingrowth in the tendon may be a reaction to repetitive loading and a response to injury.45 In normal tendon repair, sensory nerve ingrowth correlates with increased nociception, followed by autonomic nerve ingrowth, coinciding with decreased nociception and subsequent nerve retraction.one,2 In tendinopathy, the ingrown sensory nerves do not retract.41 Neuronal dysregulation, characterized by aberrant sensory nerve sprouting, may reflect a failed healing response, increased pain signaling, and the hyperproliferation of tendinopathy.41

In addition to pain transmission, peripheral nervus fibers react to mechanical stimuli and release several chemical substances in healing and homeostasis. During prolonged release, these cause fibrosis.2 Essential neuromediators are present in tendon.2,67 Tendinopathic tendons exhibit increased sensory neuropeptide substance P (SP), which plays a role in nociception and proinflammatory and trophic actions.2,3,41,66 SP regulates vasodilation, plasma extravasation, and release of cytokines past binding to neurokinin 1 in tendon and is upregulated by loading.2,6,xi,34,42,65 SP stimulates proliferation of fibroblasts and endothelial cells and may transform fibroblasts into myofibroblasts by increasing the production of TGF-β in fibroblasts.2,34 Upregulation of SP may contribute to tendinosis—that is, fibrosis (tenocyte transformation, hypercellularity, and hypervascularization).

The neurotransmitter glutamate and its receptor, NMDAR1, are in morphologically transformed tenocytes, endothelial and adventitial layers of neovessel walls, and sprouting nervus fibers.4,49,64

Anatomic Adaptations of the Throwing Athlete'due south Elbow with Ramifications for Rehabilitation

Adaptation occurs in the overhead athlete'southward elbow in range of motion, laxity, and muscular compensation. Comparison to the contralateral nondominant extremity is often complicated by these asymmetric anatomic developments.

Range of Motion Adaptations

Fifty percent of pitchers have a flexion contracture of the ascendant elbow, with 30% demonstrating a cubitus valgus deformity.37 Elbow flexion contractures averaging 5° were common in 40 healthy professional baseball pitchers.22 Directly related to elbow function was wrist flexibility, which was three° less on the dominant arm for extension and iii° greater on the dominant side for flexion compared with the nondominant extremity.22 In 33 throwing athletes prior to the competitive flavour, the average loss of elbow extension was vii°, and the average loss of flexion was five.5°.82

Several studies have shown consistent alterations of shoulder rotation in the overhead athlete, with statistically greater dominant shoulder external rotation and less internal rotation in professional person baseball pitchers.24,68,80 Despite these differences in internal and external rotation, the total rotation (internal + external) betwixt extremities remained equal such that whatever increases in external rotation were matched past decreases in internal rotation in this uninjured population. Elite-level tennis players had significantly less internal rotation and no pregnant departure in external rotation on the ascendant arm, as well as an overall decrease in total rotation range of motility on the ascendant arm of approximately 10°.24 Conscientious monitoring of glenohumeral range of motion is recommended for the athlete with an elbow injury. Decreases in ascendant arm internal rotation (glenohumeral internal rotation deficits) often occur in throwing athletes with ulnar collateral ligament injury.16 The comprehensive evaluation of the throwing athlete must include measurement of shoulder internal and external rotation with 90° of abduction, scapular stabilization, and management of internal rotation range of move loss.24

Ligamentous Laxity

Manual examination of the elbow for medial and lateral laxity can exist challenging; humeral rotation and small increases in joint opening are frequently present with ulnar collateral ligament injury. A critical-level increment of 0.v mm in medial elbow articulation opening in elbows with ulnar collateral ligament injury has been suggested with stress radiography.61 Increases in medial joint laxity can increase stress to the medial muscle tendon units to compensate for medial ligamentous laxity.v

Muscular Adaptations: Wrist and Forearm Forcefulness Profiles in Elite Throwing Athletes

Professional throwing athletes have significantly greater wrist flexion and forearm pronation strength on the dominant arm (15%-35%) compared with the nondominant extremity with no difference in wrist extension or forearm supination strength betwixt extremities.21 In professional baseball pitchers, there is 10% to xx% greater elbow flexion strength on the ascendant arm, as well as 5% to fifteen% greater elbow extension strength.79

Clinical Evaluation of the Athlete'south Elbow

A thorough evaluation of the athlete's elbow is necessary to rule out other concomitant injured structures and, most important, to identify the underlying crusade of the tendon injury. Evaluation of the entire upper extremity kinetic chain with a particular focus on shoulder and scapular strength, motion, and stabilization, coupled with diagnostic imaging and clinical tests for the distal upper extremity, is needed (Figure ane). Overuse injuries in the elbow frequently occur with shoulder or scapular dysfunction.xviii,21,43,l,52,55

Nonoperative Treatment Concepts

Based on the healing response of the human tendon, several specific phases can exist followed during nonoperative handling of elbow tendinosis: protected function, total arm strength, and return to activity. Each plays a critical function in the comprehensive treatment of elbow tendinosis.

Protected Office

During this first phase, care is taken to protect the injured muscle tendon unit of measurement from stress but non from role. Often, all sport activity must terminate temporarily to let the muscle tendon unit of measurement time to heal and to allow formal rehabilitation to progress. Immobilization can atrophy the musculature and negatively affect the upper extremity kinetic concatenation.51,55 Abeyance of throwing and serving for medial-based humeral symptoms is indicated. Allowing batting and fielding activities in baseball or hitting double-handed backhands in lawn tennis continues activity while minimizing stress to the injured expanse. Continued work or sports may slow the progression of resistive practise and physical therapy.

Modalities are very helpful during this period; withal, understanding on a superior modality does non exist.10,39,74 A meta-analysis of 185 studies on treatment of humeral epicondylitis showed glaring deficits in the scientific quality of the investigations, with no superior treatment approach.39 In a comprehensive review of the treatment for humeral epicondylitis, no significant difference was found with low-energy lasers, acupuncture, extracorporeal shockwave therapy, or steroid injection.10

Cortisone injection has been used during the hurting-reduction stage of recalcitrant conditions. Traditional physical therapy and cortisone injection were compared in 70 patients with humeral epicondylitis.15 The cortisone injection produced initial relief in 91% of patients compared to 47% undergoing concrete therapy. After 3 months, 51% of the cortisone injection group and merely 5% in the physical therapy grouping had a render of primary symptoms. Similar findings were reported with Mills manipulation and cross-friction massage and corticosteroid injection in a prospective randomized controlled clinical trial in 106 patients with humeral epicondylitis.77 At 1 year, there were no differences between treatment groups.

In a double-blind randomized controlled trial of autologous platelet-rich plasma in patients with humeral epicondylitis, 49% had a successful response (25% reduction in visual analog score and Disabilities of the Arm, Shoulder and Hand score) in the cortisone group compared with 73% in the platelet-rich plasma group.56

In 199 patients with humeral epicondylitis treated with iontophoresis with dexamethasone, 52% improved, with only 33% of the placebo group reporting improvement after ii days.52 At that place was no statistical difference in the overall improvement 1 month following treatment. Greater pain relief was seen with six treatments in a 10-day menstruation.

In a multicenter prospective randomized control study, extracorporeal shockwave therapy was ineffective in 272 patients with humeral epicondylitis.31 Similarly, low-intensity Nd:YAG laser irradiation at vii points along the forearm, 3 times a week for 4 weeks, was ineffective.8

A standardized modality or modality sequence has not been identified that is statistically more than effective. Cryotherapy post-obit increases in daily activity is recommended.51,55 Therapeutic modalities and cortisone injection can only be one part of the handling sequence; increasing evidence favors progressive resistive exercise.13,28,57,71,75

30-eight patients with lateral humeral epicondylitis were randomly assigned to a contract-relax stretching or eccentric do treatment group.71 Seventy-one percent reported full recovery in the eccentric practise group, with 39% in the contract-relax stretching group. Eccentric exercise produced a significant reduction in pain and eliminated force deficits in the wrist extensors and forearm supinators.xiii

Rubberband flexible bar (Thera-Ring FlexBar, Hygenic Corp, Akron, Ohio) produces an eccentric overload to wrist and forearm musculature in patients with lateral humeral epicondylitis. A twisting exercise to eccentrically load the elbow extensor musculature showed superior results to traditional rehabilitation (Figure 2).75 Adaptation to medial humeral epicondylitis is also possible (Effigy 3). The FlexBar preloads the wrist and finger musculature, followed by a slow eccentric contraction. Multiple sets of xv repetitions are recommended75 with discomfort (visual analog scale levels 3-iv).71

80-1 patients with a 3-month history or greater (mean elapsing, 107 weeks) of chronic lateral elbow pain were randomly allocated to a concentric and eccentric exercise or command grouping for a 3-month period.58 Starting with a water container (ane kg for women; 2 kg for men), wrist flexion and extension were increased by one-tenth when subjects performed 45 repetitions (three sets of xv repetitions). After 3 months of preparation, 72% of the exercise group had a 30% reduction of pain with the maximal voluntary muscle provocation examination, as compared with 44% in the control group.

Specific Applications of Exercise for Elbow Tendon Rehabilitation: Total Arm Strength Rehabilitation Approach

Resistive exercise for humeral epicondylitis focuses on the principle that "proximal stability is needed to promote distal mobility."69 Initially, focus is on the rotator gage and scapular musculature (Table 1).vii,9,17-nineteen,23,73 A low-resistance, high-repetition exercise format (ie, 3 sets of fifteen-20 repetitions) is followed to better strength and local muscular endurance.25 Gage weights allow rotator cuff and scapular exercises to be performed with the weight proximal to the elbow to minimize overload at the elbow and forearm.

Distal Upper Extremity Exercise

Initially (for lateral elbow tendon injury) practice of the distal extremity stresses the injured muscle-tendon unit of measurement last: wrist flexion and forearm pronation. Gradual addition of wrist extension and forearm supination, as well as radial and ulnar divergence exercises, are added as signs and symptoms permit. Initially, near patients tolerate the exercises better in slight elbow flexion with light weights. Eccentric exercise may have a greater benefit than the concentric portion.13,71 Multiple sets of 15 to twenty repetitions are recommended to promote muscular endurance.

Once the patient tolerates the most basic series of distal exercises, simultaneous wrinkle of the wrist and forearm musculature is added during elbow flexion/extension (brawl dribbling [Bodyblade, Hymanson, Texas]; FlexBar oscillation [Thera-Band]; seated rowing). Additionally, closed kinetic concatenation exercises (quadruped rhythmic stabilization) are added to promote cocontraction and mimic functional positions with joint approximation.20 Gentle passive stretching and supine combined stretches are indicated to optimize the muscle tendon unit length to elongate the biarticular muscle tendon units of the elbow, forearm, and wrist using a combination of shoulder, elbow, wrist, and forearm positions.21

When the patient tolerates the distal isotonic do progression pain-costless (3-5 lb or medium elastic tubing or bands) and oscillatory-type exercises, he or she progresses to isokinetic and plyometric exercise (Effigy 4). Contractile velocities ranging betwixt 180° and 300° per 2d with 5 or half-dozen sets of 15 to 20 repetitions are used to foster local muscular endurance25 in athletic patients with slower contractile velocities (120° to 210° per second). Plyometric wrist snaps (Figure 5) and wrist flips (Figure six) train the active elbow for functional and sport-specific demands.79

Return to Activity

The return-to-activity phase is often ignored or cut short, resulting in serious consequences or reinjury (Table 2). Objective criteria for this phase are strength equal to the contralateral extremity and a pain-free range of movement.

Table 2.

Nirschl tendonosis pain phases.

Phase 1: Mild pain afterward exercise activity, resolves within 24 hours
Stage two: Pain later on exercise activity, exceeds 48 hours, resolves with warm-up
Phase 3: Pain with exercise activeness that does not alter activity
Phase iv: Hurting with exercise action that alters activity
Phase 5: Hurting caused past heavy activities of daily living
Phase half-dozen: Intermittent pain at residue that does non disturb sleep, hurting acquired past low-cal activities of daily living
Stage vii: Abiding residue pain (dull aching) and pain that disturbs sleep

Interval sport return programs utilize alternating days, gradual progressions of intensity, and repetitions of sport activities. For the interval tennis plan, low-compression tennis balls decrease impact stress and increase the tolerance of action (Effigy 7). Supervision of the interval programme allows for biomechanical evaluation and guards confronting overzealous intensity levels, a common error in well-intentioned, motivated patients. The alternate-day return plan, with residue betwixt sessions, enhances recovery and decreases reinjury.21,23,79

Inspection and modification of the patient'southward lawn tennis racquet or golf clubs is of import. Lowering the cord tension and a softer string (coreless multifilament synthetic string or gut) are widely recommended for patients with upper extremity injuries.18,51,53,55 Grip size is also very important, as muscular activity changes can change handle or grip size.three Proper grip size should correspond to the altitude measured with a tape from the distal tip of the ring finger, along the radial border of the finger, to the proximal palmar crease or allow for the width of the contralateral 5th finger to be placed between the thenar eminence and the longest finger while gripping the racquet21,51,53,55 (Effigy 8). A counterforce brace tin decrease stress on the insertion of the flexor and extensor tendons during piece of work or sport activity.thirty

The biological goals of nonoperative physiotherapy are neovascular enhancement and mature collagen production with associated comeback in muscular strength, endurance, and flexibility. Failure of a quality program may warrant surgical intervention. Nigh patients with elbow tendinosis respond to the nonoperative program.

Surgical Concepts

The principles of surgical intervention are full excision of the unhealthy pain producing angiofibroblastic tendinosis tissue, enhancement of vascular access to the surgical site, and preservation of normal tissue.51 Techniques that fail to place and excise tendinosis tissue and release normal tendons are not recommended. Failed surgery is well-nigh always related to inadequate excision of tendinosis tissue with or without excessive release of normal tissue (eg, lateral epicondyle, extensor digitorum communis, and lateral ligaments).51,54 The mini-open techniques have reported success rates of 95% and 97% for medial and lateral tissue, respectively.55 The key pathological tissues are in the extensor carpi radialis brevis and extensor digitorum communis lateral, pronator teres and flexor carpi radialis medial, triceps posterior, and distal biceps anterior.51,55

Ulnar nerve neurapraxia is oft associated (fifty%) with medial elbow tendinosis and may require decompression of the cubital tunnel.51,55

Summary

Identifying the specific tendon pathology and understanding the healing mechanism will help clinicians guide patients through the rehabilitation process.
