1/165. The treatment of immature heterotopic ossification in spinal cord injury with combination surgery, radiation therapy and NSAID.Heterotopic ossification (HO) is a frequent complication associated with spinal cord injury. Management of HO consists of a combination of range-of-motion, diphosphonates, nonsteroidal antiinflammatory agents, radiation therapy, and in some cases, surgical resection. The appropriate timing of surgical resection has traditionally been based on maturity of the HO. The case presented is that of a 33-year-old male with T8 complete paraplegia who developed HO about the left hip resulting in impaired sitting. The patient underwent successful surgical wedge resection of the HO despite apparent immaturity of the HO. A comprehensive review of the literature is presented which suggests that early resection of immature HO may not be predictive of a higher recurrence rate.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
2/165. Extensive post-traumatic ossification of the patellar tendon. A report of two cases.Two men, aged 21 and 50 years, were seen with ossification of the patellar tendon after injury to the knee in adolescence. They complained of pain and had patella alta. Large bony masses were excised from below the affected patellae. The patellar tendon was then reconstructed using a Leeds-Keio ligament. The results at six and ten years, respectively, were good, with neither patient having pain or an extension lag.- - - - - - - - - - ranking = 0.23829402314715keywords = injury, trauma (Clic here for more details about this article) |
3/165. Heterotopic bone formation in association with pelvic fracture and urethral disruption.PURPOSE: The initial and secondary management of pelvic fracture associated with disruption of the membranous urethra is the subject of a wide literature containing varied and controversial viewpoints. We have noted the presence of heterotopic bone formation surrounding the area of urethral injury in patients undergoing delayed repair. We investigated the etiology, incidence and risk factors associated with such an injury, as well as potential means of prophylaxis. MATERIALS AND methods: We reviewed the current literature on heterotopic bone formation with similar traumatic injury. While instances of severe urethral disruption of this type are fortunately rare in children we describe prepubertal boys with such an injury complicated by heterotopic ossification. RESULTS: The incidence of heterotopic ossification reported in children and adolescents is 3 to 15%, which is less than 15 to 80% reported in adults. risk factors associated with traumatic heterotopic ossification include prolonged operating time, hematoma formation, degree of bony debris, devitalized muscle and concomitant infection. Prophylaxis with single low dose radiation or nonsteroidal anti-inflammatory drugs has been shown to be effective in the prevention of heterotopic ossification and may be beneficial in this patient population. CONCLUSIONS: Heterotopic bone formation associated with severe traumatic injury in the presence of devitalized tissue resulting in the pathological formation of new bone is rare. This complication is only associated with the most severe pelvic fractures. Prophylaxis in these most severe cases with low dose radiation or nonsteroidal anti-inflammatory drugs can prevent the formation of heterotopic bone.- - - - - - - - - - ranking = 1.0287205173604keywords = injury, trauma (Clic here for more details about this article) |
4/165. Current therapy in the management of heterotopic ossification of the elbow: a review with case studies.Heterotopic ossification, or the appearance of ectopic bone in para-articular soft tissues after surgery, immobilization, or trauma, complicates the surgical and physiatric management of injured joints. The chief symptoms of heterotopic ossification are joint and muscle pain and a compromised range of motion. Current therapies for prevention or treatment of heterotopic ossification include surgery, physical therapy, radiation therapy, and medical management. Unlike heterotopic ossification of the hip, heterotopic ossification of the elbow has not been extensively investigated, leaving its optimal management ill-defined. To remedy this deficiency, we review risk factors, clinical anatomy, physical findings, proposed mechanisms, and current practice for treatment and prevention of heterotopic ossification. We then consider and draw conclusions from four cases of elbow injury treated at our institutions (three complicated by heterotopic ossification) in which treatment included surgery, radiation therapy, physical therapy, and medical therapy. We summarize our institutional practices and conclude with a call for a randomized clinical trial to better define optimal management of heterotopic ossification of the elbow.- - - - - - - - - - ranking = 0.20957350578679keywords = injury, trauma (Clic here for more details about this article) |
5/165. Unilateral osseous bridging between the arches of atlas and axis after trauma.STUDY DESIGN: This is a case report. OBJECTIVE: To present a case of osseous bridging between C1 and C2 of posttraumatic origin and with an associated closed head injury and to discuss its pathogenesis and clinical outcome after surgical resection. SUMMARY OF BACKGROUND DATA: Heterotopic ossifications of posttraumatic origin in the spine are rare. To the authors' knowledge, no cases have been reported of spontaneous bony bridging between C1 and C2 with a posttraumatic origin. methods: Heterotopic ossifications were detected when pain and limited axial rotation (left/right 10 degrees/0 degree/20 degrees) were persistent, despite intensive physical therapy. Because heterotopic ossifications were ankylosing C1 and C2, the decision was to resect the osseous bridge in combination with a careful mobilization of the cervical spine. Functional computed tomography was performed for analysis of the postoperative results. RESULTS: Four months after surgery, clinical examination showed asymptomatic increased axial rotation. Functional computed tomography indicated that left C1-C2 axial rotation was reduced, possibly related to impingement caused by residual bony spurs. Pathologic changes in the surrounding soft tissue may be another important factor in the persistent limitation of rotation. CONCLUSIONS: Osseous bridging between C1 and C2 may be considered when persistent pain and limited axial rotation are observed after trauma. Operative resection, together with careful intraoperative and postoperative mobilization, may be the treatment of choice.- - - - - - - - - - ranking = 0.2765880462943keywords = injury, trauma (Clic here for more details about this article) |
6/165. Severe heterotopic ossification after arthroscopic acromioplasty: a case report.Heterotopic ossification is a well-recognized complication of spinal cord injury, closed head injury, total hip arthroplasty, burns, and other trauma and has been observed in various tissues such as muscles, tendons, ligaments, and menisci. Complications of arthroscopic acromioplasty are relatively uncommon and include hematoma, traction neuropathy, infection, acromial fracture, reflex sympathetic dystrophy, and instrument breakage. However, little has been reported on heterotopic ossification of the shoulder, particularly after arthroscopic surgery. Recurrent rotator cuff impingement symptoms caused by small amounts of heterotopic ossification after arthroscopic acromioplasty have been described. We report a case of severe heterotopic ossification about the shoulder after arthroscopic acromioplasty.- - - - - - - - - - ranking = 0.40957350578679keywords = injury, trauma (Clic here for more details about this article) |
7/165. Spontaneous fracture of an ossified stylohyoid ligament.The stylohyoid ligament extends from the styloid process to the hyoid bone. For an unknown reason it occasionally ossifies and forms a solid structure which can break because of trauma or even spontaneously. Symptoms of the fracture may mimic tumours, foreign bodies, infections or neuralgia. In our cases a spontaneous fracture of totally ossified stylohyoid ligaments presented as a painful neck swelling. The diagnosis was achieved by an ortopantomographic radiograph. In both cases the healing was spontaneous and complete.- - - - - - - - - - ranking = 0.009573505786787keywords = trauma (Clic here for more details about this article) |
8/165. Ossifying fasciitis.A case of ossifying fasciitis occurring in the left femoral region of a 57-year-old male is reported. The patient complained of pain in his left lower extremity which was the site of previous catheterization. During a left femoropopliteal by-pass, a firm and cylindric mass measuring 5 x 3 x 2.5 cm in size was found and extracted from the left groin. Histologically, a reactional lymph node and an irregularly shaped lesion extended into the perinodal fat tissue which is composed of proliferating fibroblasts with occasional mitotic activity. Within this fibroblastic proliferation, immature woven bone composed of osteoid with calcification and chondroid differentiation were seen. Metaplastic bone is an uncommon finding in cases of nodular fasciitis, parosteal fasciitis, cranial fasciitis and florid reactive periostitis. Ossifying fasciitis is known as an uncommon variant of nodular fasciitis. It is an uncommon post-traumatic benign lesion of subcutaneous tissue with an unclear etiology of ossification which is neither related with a bony structure nor contains any muscle tissue. This lesion has been reported only once previously, in the femoral region after a trauma history of catheterization.- - - - - - - - - - ranking = 0.019147011573574keywords = trauma (Clic here for more details about this article) |
9/165. osteonecrosis after treatment for heterotopic ossification in spinal cord injury with the combination of surgery, irradiation, and an NSAID.STUDY DESIGN: Case report. OBJECTIVE: Heterotopic ossification (HO) is a frequent complication in spinal cord injury (SCI) that is often difficult to treat. Although surgery may become necessary, operative resection has been associated with complications and poor outcome due to a high recurrence rate. Additional methods of treatment to reduce the recurrence rate have been developed, including post operative irradiation and NSAIDs. This article presents three patients, who developed an osteonecrosis of the femoral head after the combined treatment for HO of surgery, irradiation, and an NSAID.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
10/165. ureteral obstruction after kidney transplantation secondary to bone metaplasia.We report a case of ureteral obstruction after kidney transplantation caused by localized bone metaplasia in the donor ureter. Surgical treatment consisted of removal of the involved ureteral segment, which was located 3 cm above the bladder and creation of a spatulated end-to-end anastomosis. Although bone metaplasia has been observed in the ureteral wall of some animal species secondary to experimental ischemia and microtrauma, it is exceedingly rare in humans and has never before been documented after kidney transplantation.- - - - - - - - - - ranking = 0.009573505786787keywords = trauma (Clic here for more details about this article) |
