Dive-related injuries in the Keys

Medically reviewed by Jason Pirozzolo, DO, sports medicine and family medicine, Key West Concierge Orthopedics. Last reviewed July 2026.

A six-pack dive boat works the reef line off Key West: tanks racked, six divers cycling up the ladder in full gear between sites. This page covers the musculoskeletal side of that day, the shoulders, backs, and calves that diving loads hardest. One scope line before anything else: suspected decompression sickness or barotrauma is an emergency for dive medicine, not orthopedics. Joint pain after a dive with unusual fatigue, numbness, rash, or breathing trouble means contact Divers Alert Network and call 911 first; every orthopedic question on this page waits behind that one.

The reason that line comes first: decompression sickness loves to impersonate orthopedic injury. Its most common presentation is joint pain, often in a shoulder or elbow, arriving hours after a dive, exactly when a strained muscle would also be speaking up. No exam maneuver on a dock reliably separates the two. What separates them is the company the pain keeps and the timeline it follows, and that judgment belongs to dive medicine. When the story includes recent depth and any doubt at all, the correct order is DAN first, orthopedics second.

The injuries we actually see in this sport here

Ladder-climb shoulder strain

Climbing a boat ladder in full kit means hauling your body plus roughly forty pounds of gear, one arm at a time, while the swell moves the target. The rotator cuff does that work at the worst angle in its catalog: loaded, overhead, and hurried. Do it a dozen times a day for a dive weekend and the tendon complains the way tendons do, soreness first, then pain during the climb itself. The mechanism matches rotator cuff tendinopathy; mild strains settle over 2 to 6 weeks per AAOS OrthoInfo ranges, and repeated provocation stretches that badly.

Tank-lift back strain

The worst lifts of a dive day happen in parking lots and on rocking swim platforms: a full tank plucked out of a truck bed at arm's length, or twisted out of a rack while the boat rolls. The lumbar spine dislikes exactly that combination of flexion, rotation, and distance from the body. The result is usually a muscular strain, sore for days to a few weeks, with the pattern covered on the low back pain page. Crews that stage tanks at the transom and pass them at waist height save more backs in a season than any brace; asking for that handoff is technique, not weakness. Pain that runs down a leg or any numbness moves it out of the strain category and into an evaluation.

Fin-kick calf and ankle overload

Long surface swims against current, stiff new fins, and a year of not swimming add up in the calf. Cramping mid-swim is the acute version; a strained gastrocnemius that stays sore for weeks is the souvenir version. Dehydration and cold water both lower the cramp threshold, which is why the third dive of a hot day is the one that seizes. Managing it in the water is worth rehearsing: signal, float, extend the leg and flex the fin tip toward you until it releases, then finish the swim at half effort. The mechanism and recovery staging live on the calf strain page. Typical strains resolve over 2 to 6 weeks depending on grade; a pop with immediate weakness is the finding that needs eyes on it.

The Keys factor

Mini-season is the biggest one: the two-day sport lobster season, July 29 and 30 in 2026 per the FWC calendar, is the most injury-dense diving window of the year. Thousands of divers who have not touched gear since last summer load boats, climb ladders, and wrestle catch bags in crowded water on consecutive days. The pattern repeats every year: gear serviced in a hurry, a first ladder climb since last August, and a shoulder that files its complaint on the second morning. Add the standing local realities, heavy gear on small boats, hot decks, and surface swims that are longer than they looked from the boat, and the orthopedic caseload writes itself. Vacation divers can cut most of that risk in two weeks; the pre-trip conditioning guide covers the legs, grip, and shoulder work that a dive trip actually demands, and the visiting athletes guide covers what happens if the trip bites anyway.

Self-care that is reasonable

For clear muscle strains with no red flags: relative rest, ice early, and load changes such as having a buddy stage tanks, using the tag line instead of muscling the ladder, and splitting carries. Small technique changes carry most of the prevention weight too: hand the camera and catch bag up before climbing, keep fins on until both hands own the ladder, and doff the rig in the water on rough days if the boat allows it, because a ladder climb without forty pounds of gear is a different sport. Give tissue the days it asks for before repeating the exact provocation. The honest limits: weakness that persists, numbness anywhere, a joint that locks or gives way, or any post-dive symptom pattern that could be decompression sickness. The first three earn an orthopedic evaluation; the last one goes to DAN and 911 before anything else, every time.

Getting back on the boat

Boat mobility after a knee or leg injury is its own skill; the knee and boat deck guide stages it honestly, and the return-to-sport library covers shoulders and backs the same way.
