Haglund’s deformity — the bony prominence at the back of the heel — causes Achilles bursitis that can be mistaken for tendinopathy for years, and the specific surgical technique used to remove it determines whether the Achilles tendon attachment is preserved or requires reattachment. Call (810) 206-1402 — expert podiatric care across Michigan.
Haglund deformity — a bony enlargement of the posterior-superior calcaneus — causes retrocalcaneal bursitis and Achilles tendon irritation where the tendon inserts onto the heel. Known colloquially as “pump bump,” it is aggravated by rigid heel counters in dress shoes and athletic footwear. Surgery is indicated when 3-6 months of conservative care (heel lifts, soft heel counter shoes, physical therapy) fails to resolve pain and imaging confirms the bony prominence is the source of impingement. We don’t use cortisone injections here: so close to the Achilles, a steroid shot can weaken the tendon and raise the risk of rupture.
Haglund Surgery Options Compared
| Approach | Technique | Advantage | When Used |
|---|---|---|---|
| Open calcaneal exostectomy | Posterior or lateral incision; direct visualization; bone resected with osteotome/burr; bursa excised | Complete resection; direct Achilles inspection; best for severe deformity | Large Haglund prominence; Achilles tendon pathology requiring concurrent repair |
| Endoscopic calcaneal exostectomy | 2-portal endoscopic technique; shaver and burr under scope visualization | Smaller incisions; faster recovery; lower wound complication rate; same resection quality in skilled hands | Isolated Haglund without significant Achilles tendinopathy; high-demand athlete who needs faster return |
| Calcaneal osteotomy (wedge/displacement) | Closing wedge osteotomy of calcaneus to reduce posterior-superior prominence mechanically | Preserves more native bone; reduces retroachilles stress without directly entering Achilles | Combined rearfoot malalignment contributing to impingement; rarely indicated as sole procedure |
| Concurrent Achilles repair | Central tendon splitting or anchor repair if insertional tendinopathy with calcification present | Addresses combined pathology in one surgery | Insertional Achilles tendinopathy with calcification plus Haglund; adds 4-6 weeks recovery |
Recovery Timeline After Haglund Surgery
| Phase | Timing | Activity | Goal |
|---|---|---|---|
| Immobilization | 0-4 weeks | NWB or heel-touch WB in cast or posterior splint; elevation; no plantar or dorsiflexion loading | Wound healing; prevent Achilles tension on repair site |
| Protected loading | 4-8 weeks | CAM boot with heel lift; progressive weight-bearing; gentle ROM at 6 weeks | Begin Achilles mobilization; prevent equinus contracture |
| Rehabilitation | 8-14 weeks | PT: eccentric calf loading; proprioception; gait retraining; transition to running shoe with soft heel counter | Restore full dorsiflexion; eccentric strength; no rigid heel counter |
| Return to sport | 4-6 months | Running at 4-5 months; cutting sports at 5-6 months; no rigid heel-counter shoe for 6 months | Sport-specific functional testing before clearance |
At Balance Foot & Ankle in Howell and Bloomfield Township, Haglund deformity is confirmed with lateral weight-bearing X-ray (Fowler-Philip angle measurement) and MRI for Achilles tendon assessment before surgical planning. Endoscopic technique is preferred for isolated cases. Call (810) 206-1402.

Doctor Answer
What is Haglund’s deformity surgery and when is it needed?
Haglund’s deformity surgery removes the bony prominence at the back of the heel that irritates the Achilles tendon and overlying bursa. I recommend surgery after 3-6 months of conservative care including heel lifts, physical therapy, and footwear modification has failed. Recovery involves non-weight-bearing for 2-4 weeks followed by gradual return to activity over 3-4 months.
