1/11. myositis ossificans after a supracondylar fracture of the humerus in a child.myositis ossificans After a Supracondylar Fracture of the humerus in a child. In addition to the better known complications of supracondylar humerus fractures, myositis ossificans is often listed as a less common complication. This complication is extremely rare in children and historically has been attributed to high-energy trauma, manipulation, surgical intervention, aggressive passive range-of-motion exercises, or associated head injury. We present a case report of a 3-year-old girl who developed myositis ossificans after a low-energy supracondylar fracture of the humerus despite having been treated without manipulation, surgery, or physical therapy. This report illustrates that supracondylar humerus fractures can be complicated by myositis ossificans despite the best attempts at prevention.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
2/11. A brachial plexopathy due to myositis ossificans. Case report and review of the literature.myositis ossificans (MO) is a disorder characterized by the intramuscular proliferation of fibroblasts and osteoblasts, with subsequent deposition of bone and cartilage. A typical clinical presentation involves traumatic injury to a young adult, usually localized to the thigh, buttock, or upper arm, with resultant MO and mildly restricted range of motion in adjacent joints. Rarely, MO is associated with peripheral neuropathies involving the radial, median, sciatic, and sural nerves. The authors present an unusual case of MO causing a brachial plexopathy. To their knowledge, this is the first description of such a presentation.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
3/11. Pseudomalignant myositis ossificans of the wrist causing compression of the ulnar nerve and artery. A case report.myositis ossificans (MO) is a condition characterised by focal, benign and self-limited idiopathic heterotopic bone formation. It is extremely rare in the hand and wrist and may lead to concomitant nerve compression. Because of the rare incidence of pseudomalignant MO at the wrist and hand, we found it of interest to report a case of this condition localised to the wrist. A 31-year-old female patient presented with swelling and pain of her left wrist. The physical examination findings, magnetic resonance imaging and Tc-99m bone scan suggested acute osteomyelitis or a tumoral condition. Incisional biopsy and pathological examination was done. The microscopic findings confirmed that the lesion was pseudomalignant MO. The lesion was removed totally and decompression of the ulnar nerve and artery was achieved. The patient regained full asymptomatic range of motion of all digits and wrist and the numbness of the fourth and fifth digits had subsided at follow-up five months later.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
4/11. The spine in fibrodysplasia ossificans progressiva: a case report.STUDY DESIGN: A case report of fibrodysplasia ossificans progressiva (FOP). OBJECTIVES: To report a very rare cause of back pain. SUMMARY OF BACKGROUND DATA: FOP is an autosomal dominant disorder with overexpression of bone morphogenetic protein 4 and negative HLA B27. Pathognomonic are congenital malformations of the big toes. methods: The authors report on a patient with FOP who presented with back pain at their outpatient clinic. RESULTS: On physical examination, several indurated masses were visible and palpable close to the left and right scapula and the thoracic spine. These were not tender or painful, nor warmed or inflamed. A significantly decreased range of motion of all levels of the spine and the shoulder were found. On the radiographs, segmentation defects of the cervical and lumbar spine as well as synostoses of the spinal processes were seen. The cervical vertebral bodies were small and unusually high. Heterotopic ossifications could be discerned in the lumbar postural muscles and the facet joints of the spine were ankylosed. Additionally to these findings, on the thoracic radiographs ossifications of the muscles of the shoulder girdle could be seen. The pathognomonic shortening of the first metatarsal bone and the proximal phalanx was bilaterally present. The surface shaded 3D-reconstruction of the computed tomography of the trunk showed multiple bulky and confluating ossifications of the shoulder girdle. The spinal processes of the thoracic spine were anklyosed by massive ossifications of the postural muscles. CONCLUSIONS: In FOP, diagnosis can be made by the typical clinical and radiological features.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
5/11. Treatment of traumatic myositis ossificans with acetic acid iontophoresis.The purpose of this case report is to document the treatment of a patient who had traumatic myositis ossificans with acetic acid iontophoresis. A 16-year-old boy developed quadriceps femoris muscle myositis ossificans as a result of a springboard diving accident. A 2% acetic acid solution was administered via iontophoresis into the myositis ossificans, followed by 8 minutes of pulsed ultrasound at 1.5 W/cm2. The treatment was performed three times per week for 3 weeks. At the conclusion of the treatments, radiographic findings indicated a 98.9% decrease in the size of the ossified mass. The patient regained full range of motion and was able to return to pain-free activity. This case report demonstrates the potential for a therapeutic program of acetic acid iontophoresis and ultrasound in eliminating myositis ossificans.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
6/11. Fibrodysplasia ossificans progressiva: case report.Fibrodysplasia ossificans progressiva (FOP) is a rare autosomal dominant disorder characterized by postnatal progressive heterotopic ossification of the connective tissue and congenital malformation of the big toes. We report on a nine-year-old girl with clinical and radiological features of FOP. She was born with bilateral hallux valgus and at the age of nine presented an indurate mass in the left cervical region that was painful. A significant decreased range of motion in all levels of the spine and shoulder girdle was found. The radiographs showed heterotopic ossification in the thoracic region. The patient had two outbreaks of the disease ("flare-ups") that were treated with prednisone 2 mg/kg/day for four days. After the "flare-ups", she had a continuous therapy with a Cox-2 inhibitor (25 mg/day) and a leukotriene inhibitor, montelukast (10 mg/day).- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
7/11. Fracture in progressive ossifying fibrodysplasia. A case report.Progressive ossifying fibrodysplasia is a rare genetic disorder of connective tissue. A 6-year-old boy sustained a fracture of the humerus and afterwards of the femur. The former fracture was treated closed and the latter with internal fixation. Both fractures healed with severe restriction of joint motion.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
8/11. myositis ossificans circumscripta: a complication of tetanus.myositis ossificans developed in a 67-year-old man recovering from tetanus. This rare complication develops in the convalescent phase of tetanus through metaplastic changes in undifferentiated connective tissue cells in areas of myocellular injury. anoxia, hematoma formation, and immobilization may be contributing factors. Permanent loss of joint motion may be the end result of this ossifying process.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
9/11. myositis ossificans of the thigh following manipulation of the knee. A case report.myositis ossificans of the thigh produced severe limitation of knee motion in a 22-year-old man after passive manipulation of a knee on three separate occasions. motion improved after excision of the bony mass and postoperative radiation to prevent recurrence. Caution is advised in passive manipulation of the knee, because repeated attempts can result in forced extension of the quadriceps muscle, periosteal damage, partial muscle tears, and interstitial hemorrhage.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
10/11. Fracture of a supracondylar humeral myositis ossificans.Although myositis ossificans is a well-known sequela of elbow trauma, reinjury to the affected region can also occur, resulting in acute symptoms from a fracture of the myositis ossificans. An 18-year-old man presented with localized pain, soft-tissue swelling, and a bony mass along the anterolateral distal humerus with restricted elbow range of motion after injury to his elbow during football. One year earlier he had sustained a similar crush injury to his elbow that resulted in a limited, although painless, arc of motion. Radiographs and tomograms established the diagnosis of a fractured supracondylar humeral myositis ossificans. Surgical excision of the large mature ossified fragment confirmed the diagnosis and restored a full range of motion of the elbow.- - - - - - - - - - ranking = 3keywords = motion (Clic here for more details about this article) |
