Bony enlargement on the back of the heel.
If you have ever noticed a hard, painful bump on the back of your heel -- especially near the top where your shoe presses -- you may be dealing with a condition known as Haglund's deformity. Often called a "pump bump" because of its association with rigid-backed footwear, this bony enlargement of the calcaneus (heel bone) can cause significant discomfort and limit your ability to walk, run, or even stand comfortably. The good news is that physiotherapy offers a highly effective, non-surgical path to recovery. At Vaughan Physiotherapy, we see patients with Haglund's deformity regularly and help them return to pain-free activity through evidence-based conservative treatment.
Haglund's deformity is a structural abnormality of the posterior-superior aspect of the calcaneus -- the upper-back corner of the heel bone. First described by Swedish orthopaedic surgeon Patrick Haglund in 1928, it presents as a visible bony prominence that projects outward from the heel. This enlargement creates mechanical irritation of the surrounding soft tissues, most notably the retrocalcaneal bursa (a small fluid-filled sac that cushions the space between the Achilles tendon and the bone) and the distal insertion of the Achilles tendon itself.
When the bony prominence repeatedly rubs against the rigid heel counter of a shoe, it triggers an inflammatory cascade. The retrocalcaneal bursa becomes swollen and inflamed -- a condition called retrocalcaneal bursitis -- and the Achilles tendon may develop insertional tendinopathy at its attachment point (Mazura et al., 2022, Journal of Orthopaedic Surgery and Research). In clinical practice, the combination of Haglund's deformity with retrocalcaneal bursitis and insertional Achilles tendinopathy is frequently referred to as "Haglund's syndrome" or "Haglund's triad."
The condition is sometimes confused with a simple heel spur, but they are distinct entities. A heel spur (calcaneal spur) typically forms on the underside of the heel at the plantar fascia attachment, whereas Haglund's deformity develops at the posterior-superior margin of the calcaneus. Accurate diagnosis is important because the treatment approach differs between the two.
Understanding why Haglund's deformity causes so much trouble requires a brief look at the anatomy of the posterior heel. Several critical structures converge in a remarkably small space:
The posterior heel angle -- sometimes measured on lateral foot X-rays using Fowler and Philip's angle or the parallel pitch lines method -- determines how prominent the calcaneal tuberosity is. Research by Tang et al. (2022, Tomography) has demonstrated that specific radiographic measurements can help clinicians quantify the severity of Haglund's deformity and guide treatment decisions. Individuals with a naturally higher posterior calcaneal angle are biomechanically predisposed to developing the condition.
Haglund's deformity arises from a combination of structural, biomechanical, and external factors:

Conservative management is widely recommended as the initial treatment approach for Haglund's deformity. A comprehensive review of the literature confirms that non-operative strategies -- centred on physiotherapy, footwear modification, and activity management -- successfully resolve symptoms in the majority of patients without the need for surgery (Mansur et al., 2020, Revista Brasileira de Ortopedia). Physiotherapy addresses Haglund's deformity on multiple fronts:
Pain and inflammation control
Manual therapy techniques, ice application, therapeutic ultrasound, and low-level laser therapy can reduce acute inflammation in the retrocalcaneal bursa and Achilles tendon insertion. Some clinics also incorporate extracorporeal shockwave therapy (ESWT), which has shown promise for insertional Achilles tendinopathy. A randomized clinical trial protocol by Mansur et al. (2017, BMJ Open) investigated shockwave therapy combined with eccentric strengthening for insertional Achilles tendinopathy, highlighting the growing evidence base for this modality.
Restoring flexibility
Tightness in the gastrocnemius and soleus muscles is a key driver of Haglund's-related pain. A structured stretching program targeting the calf complex can reduce tension on the Achilles tendon, decrease compression of the retrocalcaneal bursa, and improve ankle dorsiflexion range of motion. Physiotherapists prescribe specific stretching protocols -- including wall stretches, incline board stretches, and sustained holds -- tailored to each patient's baseline flexibility.
Eccentric strengthening
The Alfredson eccentric heel-drop protocol is a cornerstone of Achilles tendinopathy rehabilitation and is directly applicable to Haglund's syndrome. Eccentric exercises stimulate tendon remodelling, improve load tolerance, and reduce pain. They are typically performed on a step, with the patient slowly lowering the heel below the step level using body weight as resistance.
Biomechanical correction
Physiotherapists assess gait, foot posture, and lower limb alignment to identify contributing biomechanical factors. Custom or prefabricated orthotic insoles can correct excessive supination, redistribute pressure away from the posterior heel, and provide a slight heel lift that reduces Achilles tendon tension. Footwear education is an essential component -- patients are guided toward shoes with soft, flexible heel counters and adequate cushioning.
Load management and activity modification
For active patients and athletes, a graduated return-to-activity program ensures that the healing tissues are not overloaded too quickly. Cross-training with low-impact activities such as swimming or cycling can maintain cardiovascular fitness while the posterior heel recovers.
Research supports the effectiveness of conservative treatment. S et al. (2024, Cureus) reported on functional outcomes following surgical intervention for Haglund's syndrome, but importantly noted that surgery is reserved for patients who fail a prolonged course of conservative care -- underscoring that non-operative management is the appropriate starting point. Similarly, di Chio et al. (2016, BJR Case Reports) described a case of persistent Haglund's disease after conventional treatments that required innovative intervention, emphasizing that most patients respond well to standard conservative approaches before escalation is considered.
Recovery from Haglund's deformity with physiotherapy varies depending on symptom severity, duration of the condition, and patient compliance. Here is a general timeline:
Weeks 1 to 3 -- Acute Phase.
Weeks 3 to 8 -- Subacute/Strengthening Phase
Weeks 8 to 16 -- Functional Rehabilitation Phase.
Months 4 to 6 (and beyond) -- Maintenance Phase.
At Vaughan Physiotherapy, our approach to Haglund's deformity integrates multiple evidence-based techniques:
Manual therapy and soft tissue release.
Eccentric exercise programming.
Shockwave therapy (ESWT).
Therapeutic ultrasound and laser therapy
Custom orthotics and footwear guidance.
Taping and bracing
Education and self-management
Prevention is always better than treatment. Once your Haglund's deformity symptoms have resolved, the following strategies can help keep them from returning:
Choose footwear wisely.
Avoid rigid-backed shoes whenever possible. Look for shoes with a soft, padded heel counter, or wear open-backed shoes when appropriate. If you must wear dress shoes or boots with a firm heel counter, apply moleskin or gel padding to reduce friction.
Maintain calf flexibility
A daily calf stretching routine -- holding each stretch for 30 seconds, three repetitions per leg -- helps keep the gastrocnemius and soleus muscles supple and reduces tension on the Achilles tendon.
Continue eccentric strengthening
Even after symptoms resolve, performing eccentric heel drops two to three times per week as a maintenance exercise can protect the Achilles tendon from future irritation.
Use orthotic support
If you have a high-arched foot or a tendency toward heel supination, continue wearing your orthotic insoles to maintain optimal foot mechanics.
Manage training loads
Athletes should follow the 10% rule -- increasing weekly training volume by no more than 10% -- to avoid overloading the posterior heel. Incorporate rest days and cross-training into your routine.
Monitor for early signs
If you notice the beginning of posterior heel pain, redness, or swelling, address it immediately with ice, activity modification, and a return to your stretching program. Early intervention prevents the inflammatory cycle from escalating.
