progression of heterotopic ossification around the elbow after trauma
Authors
abstract
background: this study addresses the null hypothesis that there is no expansion of heterotopic ossification (ho) in the elbow beyond what can be seen early on. methods: the area of ho was measured on lateral radiographs of 38 consecutive patients that had operative treatment of ho between 2000 and 2013. measurements from radiographs obtained between 3 to 7 weeks were compared to measurements from radiographs made 3 months or more after injury. results: there was no significant difference between the average area of ho on the first (median 2.8 square centimeters, q1: 1.5, q3: 5.1) and later radiographs (median of 2.8 square centimeters, q1: 1.4, q3: 5.0) (p = 0.99). discussion: according to our results the area of ho does not expand beyond what can be seen early in the disease process.

full textShort-term outcome after resection of neurogenic heterotopic ossification around the hips and elbow following encephalitis.
Heterotopic ossification (HO) is a potential complication following brain or spinal cord injuries and diseases. Post-encephalitis HO is rare, and the number of affected joints is a prognostic predictor. A literature review revealed only a limited number of such cases, with one or two anatomical regions affected in each case. We report the case of a 21-year-old man who developed HO at the peri-a...
full textHeterotopic ossification after central nervous system trauma
Neurogenic heterotopic ossification (NHO) is a disorder of aberrant bone formation affecting one in five patients sustaining a spinal cord injury or traumatic brain injury. Ectopic bone forms around joints in characteristic patterns, causing pain and limiting movement especially around the hip and elbow. Clinical sequelae of neurogenic heterotopic ossification include urinary tract infection, p...
full textA meta-analysis of risk factors for heterotopic ossification after elbow trauma
s: The objective of this meta-analysis was to determine the incidence and identify risk factors associated with heterotopic ossification after elbow trauma. CNKI, Embase, Medline, and Cochrane central database were searched using a broad range of terms to identify original research, published all through August 2015 and identified potentially studies. Qualified studies had to meet the quality a...
full textRadiation therapy for heterotopic ossification prophylaxis acutely after elbow trauma: a prospective randomized study.
BACKGROUND Heterotopic ossification around the elbow can result in pain, loss of motion, and impaired function. We hypothesized that a single dose of radiation therapy could be administered safely and acutely after elbow trauma, could decrease the number of elbows that would require surgical excision of heterotopic ossification, and might improve clinical results. METHODS A prospective random...
