Surgery or not: the UK Heel Fracture TrialStrong evidence
The UK Heel Fracture Trial randomised 151 people with displaced breaks into the subtalar joint, at 22 UK hospitals, to a plate fitted through a long incision on the outside of the heel or to non-surgical care, with the same weight limits and physiotherapy. At 2 years, pain and function scores were the same (69.8 against 65.7 out of 100), as were general health, walking speed, foot movement and heel width. 23% had a complication or another operation after surgery, against 4% without; wound infections affected 19% against none, and 5 of the 14 infections needed another operation. Three people treated without surgery later had the joint fused for pain.
At 5 years, with 78% followed up, the scores were still the same (79.2 against 76.4), and more people had needed extra operations after surgery (10 against 4). The authors concluded that this operation isn't recommended for these fractures. The trial left out heels so deformed that the bone pressed on the outer ankle bone, and it used the long incision, so it may not apply to smaller-incision techniques.

Older trials and the Cochrane reviewMixed evidence
In a Canadian trial of 424 people, there was no overall difference, though some groups did better after surgery: people not claiming workers' compensation, younger people, those in lighter work, and those whose joint surface was rebuilt to within 2 mm. In a Swedish trial of 82, there was no difference at a year, but a trend towards better scores and less arthritis on X-ray at 8 to 12 years after surgery. A Cochrane review of 4 trials (602 people, before the UK trial) found no clear difference in function or long-term pain, more major complications after surgery (28% against 19%) and fewer later fusions (3% against 17%), from low-quality evidence.
US orthopaedic surgeons say restoring the heel's shape tends to give better outcomes and that, in most cases, only surgery can do it, while surgery risks wound problems, infection and nerve damage, and treatment without surgery can leave pain, arthritis and a limp. Your surgeon will explain which applies to your break.

Smaller incisionsEmerging evidence
Surgery through a smaller incision over the outer side of the foot (the sinus tarsi approach) had fewer wound complications than the long incision used in the UK trial: in 21 studies (2,086 people, mostly not randomised), the long incision carried 2.82 times the risk. The X-ray results were similar. This may shift the balance for some breaks, but no trial has tested it against non-surgical care.

Weight limits: why so long, and why plans differStrong evidence
UK orthopaedic standards ask for your weight-bearing status (none, limited or unrestricted) to be written down for each leg, with the reason and how long it lasts, and reviewed at every visit. Plans differ by break and hospital. In the UK trial, both groups spent 6 weeks with no weight on the foot, then 6 weeks with partial weight. The traditional aftercare after surgery is no weight for up to 8 to 12 weeks, then a quarter more each week. US orthopaedic surgeons say some people start partial weight at 6 to 10 weeks, but most wait 3 months before putting full weight on the heel.
Small, stable breaks seen in NHS virtual fracture clinics may touch the foot down for balance, or take weight as comfort allows, in a walking boot for at least 6 weeks. UK standards also say people over 60 should be considered for unrestricted weight-bearing by default.

Earlier weight after surgery: being testedEmerging evidence
In a 2025 review of 20 studies (1,051 people, mostly looking back at records), putting weight through the foot early after surgery gave good scores, with complications in 13.9%, but there was no comparison group, and no trial has yet compared early and restricted weight-bearing. A Dutch trial of 115 people (the PIONEER trial) is now testing it.

Exercise: early ankle movement, then balance and strengthEmerging evidence
We found no trial of an exercise programme after a heel fracture. In the UK trial, both groups moved the ankle and the joint below it early and had a standard physiotherapy programme. NHS leaflets start ankle and foot movements straight away: the foot up and down, turned in and out, and in circles, 10 of each, 3 to 4 times a day, without pushing into pain. Once weight is allowed and the boot is coming off, they add a calf stretch with a towel and a front-of-ankle stretch, each held for 30 seconds 3 times, balance work from feet together to one leg for 30 seconds, and heel raises, 10 times, all 3 to 4 times a day.
US orthopaedic surgeons say the exercises are often painful at first and progress may be slow, but they're needed to get back to normal activities.

Swelling, wounds and smokingEmerging evidence
Raising the foot above the hip, especially for the first 24 to 72 hours, a cold pack wrapped in a damp towel for up to 15 minutes every few hours, and early ankle movement are the NHS measures for swelling. Smoking slows bone and wound healing, US orthopaedic surgeons say, and in 16 studies (41,944 people), smokers had 1.6 times the odds of a wound infection after ankle or heel surgery, and 2.1 times the odds of a deep one. These are observational studies. NHS leaflets ask you to stop while it heals, and to tell the clinic if you have diabetes, because you may need a specialist boot.

Back to work: most people, often to lighter jobsEmerging evidence
In the UK trial, 84.4% of the people treated with surgery and 88.9% of those treated without it were back at work at 2 years. These figures come from small groups (45 and 36 people analysed for return to work), and most had changed to less physically demanding work. In a Cochrane review, two small trials suggested more people got back to their old job after surgery (27 of 34 against 15 of 27). US orthopaedic surgeons say people whose jobs need a lot of walking or climbing may need to change their work.

Blood clotsStrong evidence
NICE says consider blood-thinning injections for people whose lower leg is immobilised, if their clot risk outweighs their bleeding risk, and consider stopping them if the immobilisation lasts beyond 42 days. UK orthopaedic standards ask for a written clot risk assessment for everyone with a leg or foot injury. Know the signs of a deep vein thrombosis (DVT): throbbing pain and swelling in one calf, with red or darker skin.
