A sling does as well as surgery for most breaksStrong evidence
In the UK PROFHER trial, 250 adults (average age 66) with a displaced break at the neck of the humerus, including 3- and 4-part breaks, had either an operation, by surgeons experienced in it, or a sling, with the same rehabilitation for both. Over 2 years shoulder scores were almost identical (about 39 against 38 out of 48, where 5 points would matter), and complications, further operations and deaths didn't differ significantly. At 5 years there was still no difference, and surgery cost about £1,800 more per person.

The wider evidence agreesStrong evidence
A 2022 Cochrane review pooled 10 trials comparing surgery with no surgery (717 people, mostly women over 60, two-thirds with 3- or 4-part breaks). It found high-certainty evidence that surgery makes no clinically important difference to shoulder function at 1 or 2 years, and lower-certainty evidence that it leads to more repeat operations (about 38 more per 1,000 people). Evidence is lacking for people under 60, high-energy injuries and breaks with a dislocation.

Very complex breaks in older people: a replacement is being testedEmerging evidence
In 6 mostly retrospective studies (439 people, average age 79) with 3- or 4-part breaks, a reverse shoulder replacement gave more forward lift (about 122° against 100°) and outward turn than a sling, with similar complications, but the authors call the evidence limited. The UK PROFHER-2 trial compared a reverse replacement, a half replacement and no surgery in people over 65; when its record was last updated in December 2025, no results had been published.

Starting to move early is safeEmerging evidence
In 74 people with an impacted break, gentle movement started within 3 days gave better shoulder scores at 6 weeks and 3 months than 3 weeks in a sling, and less pain at 3 months, with no slipping of the bone. In 86 people with a 2-part break, physiotherapy within a week gave less pain and better function at 16 weeks than 3 weeks in a collar and cuff; by 2 years the difference was no longer significant. In 111 people (average age 70), 1 week in a sling did as well as 3 weeks, up to 2 years.
Reviews disagree on how sure we can be. A 2025 review of 6 trials (470 people) found early movement safe and better for function at 3 months, with no difference later, and rated the evidence moderate to high; a 2021 review found the gain too small to matter; and the 2022 Cochrane review rated the evidence very low certainty. The safe reading: early, gentle movement doesn't harm the break, and may make the first months easier.

Pendulums keep the arm moving; they don't stretch itEmerging evidence
In 17 healthy volunteers, the shoulder joint itself moved only about 7° to 14° during pendulums; most of the movement came from the trunk. So they are a gentle way to keep the arm moving early on, not a way to regain range. Large swings (about 51 cm across) made the rotator cuff work at more than 15% of its maximum, more than small 20 cm swings, so keep the circles small at first. These are lab studies in people without injuries.

Home exercise did as well as weekly physiotherapyEmerging evidence
In a Nordic trial of 72 people aged 60 and over with a 2-part break treated without surgery, 10 weeks of weekly supervised physiotherapy plus daily home exercise gave no better arm function at 3 months, or anything else at 12 months, than daily home exercise alone. A 2021 review found no evidence either way, and in PROFHER every hospital gave home exercises alongside a basic physiotherapy protocol. Ask for physiotherapy if you're struggling to regain movement.

A broken shoulder is a reason to check bones and fallsStrong evidence
After a fragility fracture at 50 or over, NICE asks for a fracture risk assessment, and it offers a bone density (DXA) scan after a single shoulder, wrist, hip or spine fragility fracture in the past 2 years. Its falls guideline recommends a full falls assessment for people who have fallen in the past year and were injured.
Exercise helps with the falls: in a Cochrane review of 59 trials (12,981 older people living at home), exercise cut the rate of falls by 23% (high certainty) and may reduce falls that break a bone by about a quarter (low certainty).
