If you are a tree surgeon who has started feeling a dull ache on the outside of your elbow after a day with the chainsaw, or a sharp pain when you grip the loppers, you are not imagining it and you are not alone. Elbow pain is one of the most common musculoskeletal injuries in arboricultural work, and it almost always has a specific physical cause rooted in the tools you use and the way the work is structured. This article explains exactly what is happening, what the early and later warning signs look like, what your employer is required to do, and what to do if the pain has already started.

What Is Actually Happening to the Elbow

The elbow is a hinge joint, but it also acts as the anchor point for the muscles and tendons that control the wrist and forearm. When those muscles are worked repeatedly under load - gripping a chainsaw bar, twisting loppers through thick stems, pulling a handsaw - the tendons that attach at the elbow are placed under repeated tensile stress. Over time, this leads to a condition known as lateral epicondylalgia (the clinical name for what most people call tennis elbow), or its counterpart, medial epicondylalgia (golfer's elbow). These are not sporting injuries that happen to affect arborists; they are textbook overuse injuries with a well-understood mechanism.

Lateral epicondylalgia affects the tendons on the outside of the elbow - the ones that extend the wrist and fingers. Chainsaw operation is a particularly efficient trigger because the machine vibrates at frequencies that force the extensor muscles to contract repeatedly and involuntarily to maintain grip. Each contraction tugs at the tendon origin. Do this for four to six hours a day, five days a week, and microscopic tears accumulate faster than the tendon can repair itself. Medial epicondylalgia affects the inside of the elbow and is more commonly associated with repetitive gripping and twisting, which loppers and manual saws demand constantly. Many tree surgeons develop both, since they switch between tools throughout the day.

How Chainsaw Vibration Makes It Worse

Chainsaws generate hand-arm vibration at frequencies that are particularly damaging to soft tissue and peripheral nerves. The vibration does not just cause direct mechanical damage to the tendon; it also interferes with the muscles' ability to control grip force precisely. A person holding a vibrating tool tends to over-grip - applying far more force than the task technically requires - because the nervous system cannot regulate grip accurately when the proprioceptive feedback is disrupted by vibration. That constant excess grip force is what loads the elbow tendons far beyond a normal day's work.

Loppers add a different problem. Long-handled loppers create high lever forces at the hand when cutting through branches more than two to three centimetres in diameter. The wrist is often held in slight extension or ulnar deviation as the handles close, which places the extensor and flexor tendons simultaneously under strain. When a tree surgeon uses both chainsaws and loppers on the same working day - which is standard practice - the cumulative load on the elbow structures is substantial.

Early Signs You Should Not Dismiss

The early presentation of occupational elbow tendinopathy is easy to miss or explain away. Most tree surgeons first notice a tenderness on the bony prominence on the outside of the elbow that is worse when they press it directly. There may be a feeling of forearm fatigue that persists into the evening rather than resolving within an hour of finishing work. Gripping a mug of tea or turning a door handle can produce a sharp twinge. Shaking hands feels uncomfortable. Many workers at this stage simply push through, attributing the discomfort to a hard week or cold weather.

Within weeks to months, if the exposure continues unchanged, the pain becomes more persistent. It may wake you at night if you roll onto the affected arm. The grip strength in the affected hand measurably decreases - you may notice this when starting machinery or carrying cut timber. In some cases the pain radiates down the forearm toward the wrist. At this stage, the tendon tissue has undergone changes that make it substantially harder to treat, and recovery timescales lengthen considerably. Waiting is the worst strategy.

What Employers Are Required to Do

Under typical occupational health regulations in most jurisdictions, employers have a duty to assess the risks from both repetitive movements and hand-arm vibration for workers who use tools such as chainsaws and loppers regularly. That duty includes measuring or estimating daily vibration exposure, assessing cumulative task loads, providing health surveillance for affected workers, and acting on the findings - not merely recording them.

For tree surgeons, this means a risk assessment must account for the combined daily exposure from all vibrating tools used across a shift, including chainsaws, pole saws, chippers and strimmers. Where the daily vibration exposure reaches the action level defined in applicable regulations, employers are required to reduce exposure through engineering controls, work rotation, and maintenance of tools. Where a worker reports elbow pain, the employer must not simply wait for the next routine review - they must arrange a referral to occupational health promptly, adjust duties where possible, and document the steps taken. Failure to act on a reported symptom is a recognised regulatory failing in most occupational health frameworks.

Controls That Actually Work, in Order

The most effective controls reduce vibration at source and limit the duration of exposure. Anti-vibration chainsaws - machines that use spring-mounted handles and vibration-dampening systems between the engine and the grip - genuinely reduce vibration transmission compared with older or unserviced equipment. The reduction is real, though not total. Keeping chains sharp and cutting bars in good condition matters enormously: a blunt chain forces the operator to press harder and hold the saw longer per cut, multiplying both the vibration dose and the grip force loading on the elbow.

Work rotation is effective when it is genuinely structured. Rotating between chainsaw work and tasks that require no powered tool - rigging, ground clearance, movement of material - breaks up vibration exposure and gives the tendon structures time between loading cycles. Rotation is only effective, however, if the break task is actually low-load; swapping chainsaws for loppers is not rest for the elbow. Anti-vibration gloves are widely used in arboriculture but should be understood for what they are: a partial control that reduces high-frequency vibration transmission to some degree while providing little or no benefit at the lower frequencies a chainsaw produces. They are not a substitute for reduced exposure time.

Tool maintenance schedules are underused as a control. A chainsaw with a worn anti-vibration mount can transmit vibration levels several times higher than the same model in good condition. Regular measurement of vibration output from tools in service - not just reliance on manufacturer data from new equipment - gives a more accurate picture of actual worker exposure.

What a Worker Should Do If the Pain Has Already Begun

The first and most important step is to report it. In many workplaces, workers with elbow pain delay reporting because they fear being seen as unable to do the job or worry it will affect their employment. In occupational health terms, early reporting is what allows an early intervention that keeps the worker in work. A problem reported at the tendon-soreness stage is far easier to manage than one that has progressed to persistent tendinopathy with grip weakness.

A referral to an occupational health practitioner - or a physiotherapist experienced in work-related upper limb disorders - should follow promptly. A qualified practitioner will assess whether the tendon is in the early reactive phase (where load management and activity modification are usually sufficient) or whether there is structural change requiring a longer rehabilitation programme. Self-managing with over-the-counter pain relief and continuing at full exposure is the pattern most commonly associated with the condition becoming chronic.

A temporary redeployment to tasks with minimal grip and vibration demand, combined with guided rehabilitation, gives most workers a realistic path back to full tree surgery duties. Complete rest is rarely the right answer; the tendon needs graduated loading to heal, but the loading must be controlled and progressive rather than the full daily dose of chainsaw and lopper work that caused the problem.

What Tree Surgeons and Employers Most Often Get Wrong

The most common misconception is that elbow pain in this line of work is inevitable - that it is simply 'part of the job'. It is not. It is a preventable injury that becomes likely when vibration exposure is uncontrolled and task rotation is unstructured. Treating it as an occupational inevitability rather than a manageable hazard is both factually wrong and, in most jurisdictions, legally indefensible if a worker later makes a claim arising from an injury that was reported and not acted upon.

A second misconception is that anti-vibration gloves provide adequate protection. They help at certain frequencies but the evidence base for their effectiveness specifically against elbow tendinopathy from chainsaw use is limited. Gloves should be used as part of a wider control programme, not as the primary or sole measure.

Finally, many workers and employers treat elbow pain as separate from chainsaw vibration risk - managing the vibration programme for hands (looking for finger blanching and numbness, which are signs of vibration white finger) while treating elbow pain as a separate ergonomic issue to be handled differently. In practice, the daily vibration dose drives both conditions, and a combined approach to exposure management, health surveillance, and early reporting addresses both simultaneously. Health at Work can support employers and workers in establishing exactly this kind of structured, evidence-based programme before symptoms become serious.
