Ski and Snowboard Injuries

Skiers and snowboarders get hurt in different places, and the reason is equipment.

A ski boot clamps the lower leg to a long lever. When you fall, the ski keeps turning and the force goes to the knee: the anterior cruciate ligament, the medial collateral ligament, and the menisci. A snowboarder has both feet fixed to one board and no poles, so a fall is broken by an outstretched hand. That loads the wrist, then the shoulder, where the collarbone, the AC joint, and the shoulder joint absorb what is left.

Skiing. Knee ligament injuries dominate. ACL tears occur when a backward, off-balance landing drives the tibia forward, or when an edge catches and rotates the knee. MCL injuries come from the classic snowplow position, and meniscus tears often accompany both. Skier's thumb, a tear of the ligament on the ulnar side of the thumb — the side facing the index finger — happens when a pole levers the thumb away from the hand.

Snowboarding. Wrist injuries are the most common, especially in beginners, and the distal radius fracture is the most common fracture. Shoulder dislocations, AC separations, and clavicle fractures come from landing on the point of the shoulder. Riders also sustain an injury skiers essentially do not: a fracture of the lateral process of the talus, easily mistaken for a sprain and frequently missed on the first X-ray.

The mechanics are consistent. Ski injuries come from rotation and leverage through a fixed boot; snowboard injuries come from falling onto a hand or shoulder with both feet strapped down. Fatigue is the common multiplier.

• Have bindings checked annually by a certified shop and set to your current weight, height, and ability.
• Wear wrist guards if you snowboard, especially while learning; the evidence that they reduce wrist injuries is strong.
• Build eccentric quadriceps and hip strength in the weeks before a trip.
• Wear a helmet. Helmets reduce serious head injury, though they do not eliminate the risk of concussion.
• Stop while you still have good form; fatigue degrades technique and reaction time.

• A pop at the moment of injury, then swelling within a few hours
• A knee that buckles, shifts, or will not fully straighten
• Inability to bear weight, or an ankle sprain not improving after a week or two
• A thumb that feels weak or unstable when pinching or gripping a pole
• A shoulder that dislocated, or a visible bump over the collarbone
• Wrist pain and swelling after a fall on an outstretched hand

Bring everything you were given on the mountain: images or discs, the urgent care note, and any brace. Repeating imaging that already exists wastes time and money, and the original films often show more than the report captured.

Examination is more reliable once swelling settles. The Lachman test identifies an ACL tear, valgus stress testing grades an MCL injury, and stressing the thumb shows whether a ligament is partly or completely torn. MRI is used when a ligament, meniscus, or cartilage injury is suspected. CT is valuable for suspected fractures of the lateral process of the talus, which routinely hide on X-rays.

Many do not. Isolated MCL tears, even complete ones, usually heal well in a hinged brace with rehabilitation. Nondisplaced fractures and partial thumb ligament tears are typically treated with immobilization, and most shoulder separations are managed without an operation.

Surgery is considered for a complete ACL tear in someone returning to cutting sport or skiing, for a repairable meniscus tear, for a complete thumb ligament tear, particularly when the torn end has flipped out of position, for displaced fractures, and for a shoulder that has dislocated repeatedly. Timing matters: for a knee, restoring full extension and quadriceps control before reconstruction reduces stiffness afterward.

• Gather outside records and imaging before your visit; it often prevents a repeat scan.
• Work on motion and quadriceps control while you wait, if a knee is involved.
• Stop nicotine, and hold anti-inflammatories and blood thinners as directed.
• Book physical therapy in advance and have crutches, a brace, and ice ready.
• Arrange a driver and help at home for the first day.

The operation depends on the injury. The most common in this group is ACL reconstruction, outlined here.

1. Anesthesia and examination. General anesthesia with a regional block, then an exam under anesthesia to grade instability.
2. Arthroscopy. The joint is inspected and meniscus and cartilage injuries treated, preserving meniscus tissue by repairing it whenever the tear allows.
3. Graft and tunnels. A graft is prepared from your own patellar, hamstring, or quadriceps tendon, or from donor tissue, and tunnels are drilled at the ligament's native footprints.
4. Fixation. The graft is secured at both ends and stability confirmed through a full range of motion.

Thumb repair, fracture fixation, and shoulder stabilization follow their own sequences, reviewed with you beforehand. More on ACL reconstruction.

Weeks 0 to 2

Swelling control, protected weight bearing where required, and early motion. For a knee, full extension and quadriceps activation come first.

Weeks 2 to 6

Bracing is weaned for most injuries, and isolated MCL injuries are often back to normal activity here. Casts and splints come off after fractures and thumb repairs.

Weeks 6 to 12

Progressive strengthening, balance, and single-leg control.

Months 3 to 5

Running, then jumping and landing work after a knee reconstruction.

Months 5 to 9

Cutting and sport-specific training.

Months 9 to 12

After ACL reconstruction, return to pivoting sport is generally not before nine months, and only once strength and hop testing are symmetric and a sport-specific progression is complete.

Returning to Snow

After ACL reconstruction most people return the following season, starting on groomed terrain well within their ability. An injury in January often means surgery in February and skiing again the next winter, so season timing is worth planning early.

Risks depend on the procedure and include infection, blood clot, bleeding into the joint, stiffness, numbness near an incision, and problems with fixation. After ACL reconstruction the graft can stretch or retear, the opposite knee is also at risk, and quadriceps weakness can persist.

Two injuries deserve specific mention. A missed lateral process talus fracture can lead to nonunion and lasting ankle pain, which is why CT is used when the story fits. An untreated complete thumb ligament tear with a displaced end will not heal and leaves a weak pinch. No surgeon can guarantee an outcome.
