Mountain Biking Injuries on the North Shore: What Hurts and What Helps

Mountain bike crashes mostly injure the upper body. The slower injuries show up later, as knee, low back, neck and hand pain after many hours on the bike. This guide covers both kinds, what the research reports, and where physiotherapy fits.

Most mountain bike injuries affect the upper body

A 2017 review by Ansari and colleagues in Current Sports Medicine Reports reports that almost two thirds of acute mountain biking injuries involve the upper limbs. A similar share of overuse injuries involve the lower limbs. An acute injury is a crash or a sudden twist. An overuse injury is pain that builds from repeated load over weeks or months.

When a rider is thrown forward over the handlebars, the natural reaction is to put out a hand, and the force goes through the wrist, elbow, shoulder and collarbone.

A British Columbia study shows how serious this can be. Ashwell and colleagues reviewed the charts of 898 injured riders who came to the Whistler Health Clinic from the Whistler Mountain Bike Park during the 2009 season. They recorded 420 fractures in 382 riders, which is 42.5% of the group. Upper limb fractures were the largest share, reported at 75.4%. Traumatic brain injury was recorded in 11.2% of the riders, and 8.5% were transferred to a higher level of care.

Read these numbers with their limits in mind. The riders were at one bike park in one season. The authors had no count of how many rides riders took, so the paper shows which injuries occurred when riders were hurt and gives no odds for any one ride.

The collarbone is the most commonly broken bone

A 2022 systematic review by Bigdon and colleagues in BMC Sports Science, Medicine and Rehabilitation concluded that fractures of the clavicle, the collarbone, are the most common injury in mountain biking. Fractures of the hand and wrist come next.

A 2021 review in International Orthopaedics gives background on the collarbone. Clavicle fractures make up between 4% and 10% of adult fractures, and the middle section of the bone accounts for more than 80% of them. Sport causes 50% to 85% of these injuries.

The usual signs are pain along the collarbone, a bump or a visible bend in the bone, and a shoulder that hurts when you lift the arm. People with a broken collarbone often support the arm with the other hand. These signs need a doctor and usually an X-ray.

Treatment depends on how far the broken pieces have moved. A systematic review of return to sport after clavicle fractures found that the usual first step for athletes with a break that has not moved is care without surgery. For a displaced break in the middle of the bone, the review recommends surgery and reports better return rates and return times. The 2021 review reaches a similar view for athletes, and adds that no randomized trial has compared surgery with a sling directly. This is a decision for you and your surgeon.

Physiotherapy begins inside the limits your doctor or surgeon sets. The aim is to keep the neck, elbow and hand moving early, then restore shoulder movement and strength after the bone is cleared to load. A fall onto the point of the shoulder can also hurt the joint where the collarbone meets the shoulder blade. Our guide to a separated shoulder explains that injury and its grades.

A broken wrist bone can look like a sprain

The Bigdon review also stresses one small bone: the scaphoid, on the thumb side of the wrist. It reports that scaphoid fractures often look subtle on examination and on X-ray, so they must stay on the list of possible causes of a sore wrist.

After a fall onto your hand, tenderness at the base of the thumb is the pattern to take seriously. Our article on wrist sprain or scaphoid fracture explains why a first X-ray can look normal and what usually happens next. A doctor decides on imaging and on whether the wrist needs protection first.

After a sprain or a healed fracture, the wrist still has to carry your body weight on a bike. Physiotherapy restores wrist movement and grip strength in steps. It also checks the elbow and shoulder, because they share the load of braking and steering.

Head, neck and spine injuries need a doctor first

Ashwell's Whistler data recorded a traumatic brain injury in 11.2% of injured riders. The Bigdon review concluded that a helmet seems to decrease the likelihood of face and head injuries in mountain sports. A helmet lowers the risk, and a head impact still needs a check afterward.

Warning signs of concussion include headache, dizziness, nausea, confusion and a gap in memory. If any of these follow a head impact, stop riding and see a doctor. Physiotherapy has a role later, in a staged return to activity once a doctor has cleared you to begin. Our concussion page covers physiotherapy for concussion.

Spine injuries are the most serious injuries in this guide. Ansari's review reports that mountain biking appears to be a high-risk sport for severe spine injuries. In 2024, Chu Kwan and colleagues from the Vancouver Spine Surgery Institute and UBC reported 58 people with spinal cord injuries from mountain biking, treated at their Level 1 trauma centre (the highest level of trauma care) between 2008 and 2022. That is a rate of 4 patients per year. Their average age was 35.5 and 93% were male.

These figures count hospital cases. Their practical value is the response after a crash. If you have neck pain after a fall, tingling, numbness or weakness in your arms or legs, stay still and call 911. Do not get up to test it.

Long rides cause knee, low back, neck and hand pain

Ansari's review reports that almost two thirds of overuse injuries in mountain biking affect the lower limbs. Knee pain is the usual example. Our article on cycling knee pain and bike fit explains how to tell a bike setup problem from a strength or movement problem.

Low back pain comes from the riding position. A 2025 study in Sports Biomechanics states that low back pain is common in mountain biking because the lower spine stays bent forward for a long time, especially on tiring hill climbs.

Neck, hands and elbows take load as well. A 2022 review of cervical spine, nerve and overuse injuries in cyclists reports that neck pain is common, that carpal tunnel syndrome and ulnar nerve irritation at the wrist affect cyclists, and that biker's elbow, a tendon pain on the inside or outside of the elbow, is more common in mountain biking. The same review recommends a bike fit assessment for any ongoing symptoms.

A physiotherapist checks how the neck, shoulders, trunk, hips and knees move and how much load each can tolerate. The plan that changes training load, adds strength work and, where needed, sends you for a bike fit. Our physiotherapy service page describes physiotherapy at the clinic.

Rehab after a crash follows a set order

Every injury has its own plan. The steps below show a common order, and your physiotherapist sets the pace.

1. A doctor rules out a fracture, a head injury or a spine injury and says what you may load.
2. You protect the injured area and keep the joints around it moving.
3. You restore movement in the injured joint.
4. You rebuild strength, including the shoulder blade muscles, the trunk and the legs.
5. You return to riding in stages: stationary or flat riding first, then easy trail, then technical descents and jumps.

You move to the next step when the last one is settled and the area tolerates the load. Healing time depends on the tissue, the type of injury and the treatment, so a physiotherapist and your doctor set dates after looking at your case.

Prevention matters as well. Ansari's review states that protective gear, technical skill and physical fitness may decrease the risk of injury, and that a correct bike fit may decrease some overuse injuries. Strength and conditioning work before the season is one way to build the fitness part.

Warning signs, and when to book

Go to the Lions Gate Hospital emergency department or call 911 for any of these after a crash:

• a head or neck injury with confusion, numbness or weakness
• loss of bladder or bowel control
• a limb that looks deformed
• inability to put weight on a leg

For an injury that is not an emergency, a doctor can confirm or rule out a fracture. Physiotherapy then helps you recover movement and strength. For ongoing pain from riding, book an assessment before the pain grows.

You do not need a referral to book physiotherapy in British Columbia. The clinic is at 1325 Marine Drive, North Vancouver, BC V7P 3E5. You can book at medstar.janeapp.com or call (604) 988-5411. Physiotherapists in BC are licensed by the College of Health and Care Professionals of BC, and you can check any name in its public registry.

A clear diagnosis and a plan in steps come first. Bring the details of the crash and any imaging reports to the first assessment, and the physiotherapist can plan around them.
