Tennis elbow

Tennis elbow – Tennis elbow is a tendinopathy of the common extensor origin
 of the lateral elbow ( John Orchard BMJ 2011 ). First described
 by Runge et al in 1873 when it was called ” writers cramp “

Tennis elbow is very common Peaks age 35-55 Dominant arm involved in majority of ( ~ 75 % ) cases Equal gender incidence Prevalence 1-3 % ( higher in manual workers ) Tennis players make only 10 % of tennis elbow cases
but 50 % of tennis players develop elbow pain and tennis elbow is responsible for 75 % of those Occurs more frequently in non-athletes Most common cause of persistent elbow pain in general practice

Etiology multifactorial Overuse injury of extensor carpi radialis brevis insertion at the lateral epicondyle of humerus Several contributory factors as
○ force
○ repetition ( forearm and elbow )
○ posture Repetitive overuse –> microtear –> initiates a degenerative process
Tendon adaptation –> granulation tissue formation , fibrosis and eventual tendinosis No evidence of acute or chronic inflammation ie not a true inflammatory process Tendons predisposed to injury due to (a) limited vascular supply (b) subject to repetitive tension forces (c) wrap around a convex surface

Risk factors- age 40-60 yrs Previous hx of epicondylitis repetitive activities ( occupational or recreational )
eg tennis , golf , rowing , baseball , kayaking
construction work , assembly line work , use of vibratory tools , playing piano , plumbing , painting poor mechanics during activities smoking ( current and previous ) inadequate physical conditioning rotator cuff pathology De Quervains disease Carpal tunnel syndrome Oral corticosteroid therapy

diagnosis is clinical based on history and examination – Pain -severity , onset , duration Exacerbating causes ask about h/o injury or ↑↑ ed level of activity
usually insidious onset with no precipitating event Social and occupational history Impact of illness eg
○ difficulty with raising cup
○ shaking hands
○ shaving
○ lifting bags with an extended elbow Patient reports
○ pain at lateral aspect of elbow
pt can point to an areas 1.5 cm distal to the lateral epicondyle
○ decreased grip strength ( due to pain )
○ tenderness at the lateral epicondyle

examination-R/O red flags Elicit typical features as
○ localised point tenderness over and / or distal to the lateral epicondyle and along common extensor tendon
○ pain associated with resisted wrist extension with the elbow extended
○ pain associated with resisted middle finger extension with the elbow extended
○ pain on wrist flexion with the elbow extended
○ weakened grip Elbow joint movements -active and passive usually preserved Consider checking neck/shoulder for referred pain Diagnosis can be verified by US or MRI Consider nerve conduction study if nerve dysfunction suspected Consider blood tests if inflammatory arthritis suspected Plain radiographs usually normal

red flags-h/o trauma joint swelling/redness systemic symptoms rapidly increasing mass

differential;l-Humeral fracture Radial head fracture Osteoarthritis Radial tunnel syndrome Primary ligamentous instability Cubital tunnel syndrome Osteochondritis dissecans of the capitellum Rheumatoid arthritis or septic arthritis Referred pain- from cervical spine Olecranon bursitis

Aim is to provide pain relief and restore physical function and maintain ability to work Non operative measures successful in > 80 % Treatment strategies can involve

○ activity modification 
○ rest
○ splint
○ physiotherapy 
○ steroid inj ( used widely )
○ acupuncture Advice patient to d/w OT if work related Offer topical NSAID ( first line CKS ) Offer information and advice leaflet. spints and  orthotics , extracorporeal shock wave therapy , atologous injection , corticosteroid injection , platelet rich plasma,  physiotherapy, surgery

summary-Usually a self limiting disease Symptoms are usually mild and prognosis is excellent Resolves in 80-90 % of people by 1-2 yrs ( conservatively ) Several modalities of treatment have been tried
No universal treatment protocol
No treatment has been shown to be superior to others Main complication is continued pain – other complications may be due to the interventions used to relieve pain

referral-Diagnostic uncertainty Severe functional limitation Refractory /severe pain Symptoms persist despite 6-12 months of management in primary care
