# Musculoskeletal disorders, backs, knees, shoulders and the long-term cost
By far the most common way people get forced out of this game is wrecked backs, knees and shoulders, not one big accident. If you're 25 and shrugging it off now, you're basically deciding what kind of shape you'll be in at 45.
Quick rule of thumb: a 25-year-old who never uses a hod, never uses knee pads and always takes the heaviest lift to prove a point is very likely to be the 45-year-old who "had to pack in" because his back or knees gave up.
1. How big the problem is in construction
- HSE's latest stats say around 511,000 workers in Great Britain are suffering from a work-related musculoskeletal disorder (MSD), with 7.1 million working days lost in a year.
- Back problems make up about 43% of MSDs, and upper limbs/neck about 41%.
- In construction specifically, work-related ill health is estimated in tens of thousands of workers, and more than half of those cases are MSDs · mainly from manual handling, awkward postures and repetitive tasks.
So this isn't "a few sore backs", it's a big chunk of the industry.
2. What the law says your employer should be doing
Manual Handling Operations Regulations 1992 (MHOR)
Under MHOR and the general duty of care:
- Avoid hazardous manual handling where reasonably practicable · use hoists, forklifts, telehandlers, trolleys, block grabs, plasterboard lifts etc. instead of straight back and arms.
- Where it can't be avoided, they must:
- Assess the risk using TILE(O): Task, Individual, Load, Environment (and Organisation).
- Reduce the risk as far as reasonably practicable · lighter loads, breaking things down, team lifts, better access routes, realistic programmes.
- Provide information, instruction and training on safe lifting techniques and how to use mechanical aids.
Construction guidance also expects employers to:
- Plan jobs so people aren't on knees, overhead or twisted all day every day.
- Rotate tasks where there's repeated heavy lifting or awkward work.
If "manual handling training" on your job was just a 10-minute video and then the usual 25kg bags up three flights with no thought, they're not doing this properly.
3. The injuries that finish people, and the trades they hit
Common MSDs in construction include:
Lower back pain / disc problems
From heavy lifting, twisting with load, shoving kit around, and years of bending over.
Knee osteoarthritis / meniscus tears
Kneeling for bricklaying, floor laying, roofing, tiling, screeding, plus carrying weight up ladders and stairs.
Shoulder injuries (rotator cuff, impingement)
Overhead work (drylining, M&E, painting), lifting boards above shoulder height.
Tendon and nerve issues
- Tenosynovitis (tendon sheath inflammation) in wrists/hands from repetitive screwing, hammering, using nail guns.
- Carpal Tunnel Syndrome · median nerve compression in wrist, linked to repetitive forceful work with flexed wrists and vibration.
Some show up as prescribed diseases for IIDB
- PD A8 · Tenosynovitis in hands/wrists from specified repetitive work.
- PD A12 · Carpal Tunnel Syndrome in people using hand-held vibrating tools for a qualifying period.
- PD A14 · Osteoarthritis of the knee in certain long-term kneeling occupations.
Trades most at risk: brickies, groundworkers, scaffolders, roofers, dryliners, floorers, painters, plasterers, M&E install, basically anyone moving heavy kit and working bent or overhead all day.
4. When MSDs are serious enough for IIDB
You may be able to claim Industrial Injuries Disablement Benefit if:
- You have one of the prescribed MSD diseases (for example, A8, A12, A14).
- You've done the specific type of work listed in the regulations for long enough.
Key points:
- IIDB is for permanent disablement from work-caused disease · not just temporary backache.
- DWP looks at diagnosis (for example, nerve tests for carpal tunnel, scans for knee osteoarthritis) and your work history (what you did, for how long, with what tools).
- They then set a percentage disablement; payments depend on that and your age.
For anything outside the prescribed list (for example, general back problems), compensation is usually via a civil claim rather than IIDB, and again, work history and early medical records matter.
5. What you can do yourself, habits that keep you working
Your employer has duties, but you've got skin in the game too. A few habits make a big difference over 10–20 years:
Use the kit, not your ego
If there's a trolley, hoist, board lifter or telehandler available, use it. This isn't "being soft", it's saving your back for later.
Split the load and the time
Half-loads, more trips is often better than hero-lifting once and tweaking something. Rotate tasks with your gang, don't let one person be "the lifter" or "the one always on their knees" every day.
Get your technique decent
Feet close to the load, bend your hips and knees, keep the load close to your body, avoid twisting, move your feet instead. If you can't get close or straight, that's a design problem, not your spine's fault.
Protect your knees and shoulders
Wear decent knee pads and use knee boards or low seats, don't spend hours straight on concrete. Use platforms or small towers so overhead work isn't full-stretch all the time.
Look after your engine
Basic strength and mobility work · legs, core, glutes, shoulders · pays off. You don't need to be a gym bro; bodyweight, bands and light weights help. Keep moving outside work · being stiff and deconditioned makes work hits worse.
Don't ignore early warning signs
If a joint or area is consistently sore, swollen, weak or numb, for weeks not days, get it checked. Seeing a physio early can stop a niggle turning into a long-term injury. Waiting until you can't walk properly is when you start talking surgery and long layoffs.
Know when to say "no"
If someone is asking you to do something clearly daft (for example, solo-carry down a staircase with no rails, move weights beyond what's reasonable), you're within your rights to push back. MHOR backs you on that.
What to do next
- If you're in pain now, see your GP or a physio this week · don't wait until it's a disc bulge or a torn rotator cuff. Early intervention saves careers.
- If your employer isn't providing mechanical aids for heavy or repetitive lifting, raise it · MHOR requires them to assess and reduce the risk, not just say "get on with it".
- If you've got a long-term MSD from site work (carpal tunnel, knee problems, tenosynovitis), look into whether it's a prescribed disease for IIDB · call the DWP helpline (0800 121 8379).
- If you're young and feel invincible, start using knee pads, mechanical aids and decent lifting habits now · your future self will thank you more than you can imagine.
