A 75-year-old woman presented to the emergency department in January 2023 with pain and swelling of the lateral left ankle after an inversion injury 1 week earlier. She underwent X-rays of the left foot, and she was diagnosed with a small, nondisplaced avulsion fracture of the lateral calcaneus as well as a large Haglund deformity of the calcaneus (Figures 1 and 2). The patient noted that she had a history of ankle pain due to a Haglund deformity, a bony prominence found on the superior posterior aspect of the calcaneus [1], [2], [3]. The deformity caused pain that worsened with ambulation. The pain also worsened when wearing sling-back shoes. It became too painful for her to walk, so she had surgery approximately 50 years ago to partially remove the deformity and lift the Achilles tendon. Since then, she has been doing well and has not had any heel discomfort.

Haglund deformities are found lateral to the insertion site of the Achilles tendon on the calcaneus [1, 4]. Several possible etiologies have been suggested, including Achilles tendon tightness, joint abnormalities, anatomical calcaneal abnormalities, genetics, tight-fitting shoes, and high-arched feet [2, 5]. Haglund deformities are commonly found in women in their 20s to middle age [1, 3, 5]. The typical presentation involves posterior heel pain and swelling that tend to worsen with walking due to inflammation of the soft tissues and often the retrocalcaneal bursa and the calcaneal tendon bursa [1], [2], [3], [4], [5]. The diagnosis is made by X-ray evaluation displaying a large bony prominence on the superior posterior aspect of the calcaneus [1, 2]. The first-line treatment of a Haglund deformity is typically conservative and involves anti-inflammatory medications, steroid injections, shoe alterations to decrease pressure in the area, and physical therapy [1], [2], [3], [4], [5]. Osteopathic manipulative treatment (OMT) can focus on the Achilles tendon, particularly counterstrain, which has been shown to be a useful technique by relieving tension on the Achilles tendon [6]. If conservative therapy fails, then surgical removal of the bony prominence is indicated [1, 3, 5]. One study found that more than 2 % of patients who underwent surgery needed additional surgery, due mainly to pain from the implanted hardware [7]. There are several possible diagnoses to consider in addition to a Haglund deformity when it comes to posterior heel pain, including but not limited to calcaneal tendon avulsion, calcaneal apophysitis, Achilles tendinopathy, and retrocalcaneal bursitis [1], [2], [3], [4]. It is necessary to be aware of Haglund deformity and to obtain imaging if it is on the differential as it can mimic several other pathologies.
