His left hip was stiff and showed a circumferential ossific mass. After initial medical management, the patient underwent excision of ossific mass using posterior approach. For adequate excision, femoral head and neck were resected and a hybrid total hip arthroplasty was performed. The patient was followed up for 2\u2009years and showed good clinical outcome without recurrence of heterotopic ossification. This case highlights the rare aetiology of neurogenic heterotopic ossification which is critical illness polyneuropathy following expanded dengue syndrome. It highlights that adequate resection and a total hip arthroplasty can be a viable option in selected cases of circumferential heterotopic ossification in old individuals.<\/jats:p>","DOI":"10.1136\/bcr-2021-246186","type":"journal-article","created":{"date-parts":[[2022,3,9]],"date-time":"2022-03-09T11:18:44Z","timestamp":1646824724000},"page":"e246186","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Neurogenic heterotopic ossificans of hips in a case of expanded dengue syndrome following critical illness polyneuropathy"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6893-4238","authenticated-orcid":false,"given":"Atmananda","family":"Hegde","sequence":"first","affiliation":[{"name":"Orthopaedics, Kasturba Medical College Mangalore, Manipal Academy of Higher Education, MAHE, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6031-1607","authenticated-orcid":false,"given":"Prajwal Prabhudev","family":"Mane","sequence":"additional","affiliation":[{"name":"Orthopaedics, Kasturba Medical College Mangalore, Manipal Academy of Higher Education, MAHE, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4459-6099","authenticated-orcid":false,"given":"Chethan B","family":"Shetty","sequence":"additional","affiliation":[{"name":"Orthopaedics, Kasturba Medical College Mangalore, Manipal Academy of Higher Education, MAHE, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6096-9337","authenticated-orcid":false,"given":"Samarth Ajay","family":"Thakkar","sequence":"additional","affiliation":[{"name":"Orthopaedics, Kasturba Medical College Mangalore, Manipal Academy of Higher Education, MAHE, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,3,9]]},"reference":[{"key":"2025082710201167000_15.3.e246186.1","doi-asserted-by":"publisher","DOI":"10.1302\/2046-3758.23.2000152"},{"key":"2025082710201167000_15.3.e246186.2","doi-asserted-by":"crossref","first-page":"1143","DOI":"10.2106\/00004623-198062070-00012","article-title":"Periarticular heterotopic ossification in head-injured adults. incidence and location","volume":"62","author":"Garland","year":"1980","journal-title":"J Bone Joint Surg Am"},{"key":"2025082710201167000_15.3.e246186.3","doi-asserted-by":"crossref","first-page":"866","DOI":"10.3109\/02699052.2015.1005133","article-title":"Troublesome heterotopic ossification and stroke: features and risk factors.
