Heterotopic Ossification After Burn Injuries Study Main Research Sample Purpose Design Crawford, 1986121 To determine Incidence of Heterotopic Ossification (HO). Djurickovic To report , 1996122 incidence of HO and results of surgical excision. Outcome Measures Results Study Level of Category Evidence Retrospective review of patients admitted to burn center. 1,066 Radiological consecutive confirmation of admissions to HO. burn center. Patients who developed decreased ROM and joint pain had x-ray. 12 patients or 1.2% had evidence of HO on X-ray. Average TBSA 49% and 6 required surgical excision. Prognostic III Retrospective review of admissions to burn unit between 1982 through 1993. 1,855 consecutive admissions to burn center. 24 patients with diagnosis of HO Prognostic or 1.2%. Elbow HO was present in 18 of the 24 cases. 15 required surgical excision. III Radiological confirmation of HO. Elledge, 1988123 To determine Retrospective Incidence of HO. review of burn injury admissions to U.S. Army Institute of Surgical Research between 1967 and 1985. 5,031 Radiological admissions to confirmation of HO burn center and review of X-rays completed during routine clinical care. HO diagnosed in 63 patients for Prognostic incidence of 1.2%. Average TBSA was 44.6% and HO was at the elbow in 82.5% of the cases. Patients with HO had a longer length of hospitalization compared to those without HO. III Gaur, 2003125 To report on Prospective, case outcome of series. surgical excision of HO. 8 children (10 elbows) with severe HO after burn injuries who underwent surgical excision. Average gain in ROM of 57 degrees. Follow-up completed on 7 children (9 elbows). IV Range of motion (ROM) before surgery and at follow-up 3 to 10 years later. Therapeutic Holguin, 1996126 To report on outcome of surgical excision of HO. Retrospective study of patients who required surgical excision for HO. No control group. 6 subjects with HO out of 2280 total patients. All 6 required surgical excision. Range of motion before surgery and at follow-up 6 months to 22 years later. Very good outcome in 5 subjects Therapeutic with average gain in ROM of 73.6 degrees. One subject was not cooperative with postoperative treatment and had poor outcome. IV Peterson, 1989124 To determine Retrospective 1,478 individuals Incidence of HO. review of admitted to burn consecutive center. admissions to burn center. All patients had decreased ROM, joint pain and x-ray confirmation of HO. 18 patients developed HO Prognostic (1.2%). 17 of the patients had HO at the elbow. 10 patients were treated conservatively and 8 with surgical excision. Both groups had a large gain in ROM. III Tsionos, 2004127 To report on Retrospective, outcome of case series. surgical excision of HO. Range of motion pre-op and at a follow-up. Mean follow-up was 21 months post-op. Significant gain in ROM. 4 elbows had recurrence of the HO. III 28 patients (35 elbows) who had surgical excision of HO at the elbow. Post-op treatment with splinting, CPM and indomethacn. Therapeutic
