NEUROGENIC HETEROTOPIC OSSIFICATION OF THE HIP : A SURGICAL MANAGEMENT

Neurogenic Heterotopic ossifications (NHO) is a condition in which unregulated spontaneous formation of bone tissue in between the muscles occurs especially around periarticular areas of large joints. Our aim of the study is to evaluate the clinical, functional and complication of the surgical management of  Neurogenic Heterotopic Ossification of the hip joints. Method and material : Medical records of 3 patients who had undergone surgical resection for NHO were reviewed in retrospect from 2018 to 2020. All 3 patients had suffered from road traffic accidents with traumatic brain injury. Preoperative x rays and CT scans were done to assess the location and size of ossification. Anterior approach was used to operate the NHO. Results: The mean age of the patients was 36.67 years. The mean age of the patients in our study was 36.67 years (28-43 years). All 3 patients were males with history of RTA. All 3 had involvement of the right hip. The mean duration from accident to presentation to our institute was 9.33 months. All patients had preoperative ambulatory score of 4. The mean postoperative ambulatory score at end of follow up period was 2.33. The mean duration of surgery was 168.33 minutes. The mean intraoperative blood loss was 1066.67cc. The average drain volume was 450cc of blood. One patient developed paresthesia and tingling sensation on an anterolateral aspect of thigh which resolved in 3 months with medication.
