Chondrodiatasis in a patient with spondyloepimetaphyseal dysplasia using the Ilizarov technique: successful correction of an angular deformity with ensuing ossification of a large metaphyseal lesion. A case report. (1/315)
Distraction through the physis (chondrodiatasis) is a controversial technique with unpredictable results. However, it has been used in the past for the lengthening and correction of angular deformities of long bones. We report the case of an 11-year-old patient with spondyloepimetaphyseal dysplasia (SEMD) who presented with a severe recurvatum deformity of the left proximal tibia secondary to collapse of the tibial plateau into a large metaphyseal cystic lesion. Using the chondrodiatasis technique with a percutaneously applied Ilizarov circular frame, we were able to correct this deformity. Surprisingly, healing and ossification of the metaphyseal lesion was simultaneously observed at the end of the treatment, a finding which, to the best of our knowledge, has not been previously reported. (+info)The immediate effect of a Boston brace on lung volumes and pulmonary compliance in mild adolescent idiopathic scoliosis. (2/315)
Idiopathic scoliosis (IS) is known to result in lung volume and pulmonary compliance reduction. Boston brace treatment of IS is an additional factor causing restrictive respiratory syndrome due to external chest wall compression. Nevertheless, the immediate effect of Boston bracing on the pulmonary compliance of scoliotic patients has not been studied systematically. Spirometric and plethysmographic lung volumes, static lung compliance (C(ST)(L)) and specific lung compliance (C(ST)(L)/functional residual capacity) of 15 scoliotic adolescents (14 females and 1 male, of mean age 14.1+/-1.67 years, with mean Cobb angle 24.1 degrees+/-7.88 degrees) were recorded twice, in a random sequence: once without the Boston brace (nBB) and once immediately after wearing the brace (BB). Our findings showed that bracing reduced vital capacity, residual volume, functional residual capacity (FRC), total lung capacity, and forced expiratory volume in 1s in a proportional and significant way (P < 0.001). C(ST)(L) was also significantly reduced (P < 0.001), but C(ST)(L)/FRC remained unaltered. All BB and nBB indices were highly correlated. We concluded that Boston bracing in IS patients results in an immediate, predictable, and uniform reduction of lung volumes and pulmonary compliance. The reduction of C(ST)(L) under bracing conditions was related to the decrease of lung volume; the C(ST)(L)/FRC remained unaltered. (+info)Bilateral anterior shoulder fracture-dislocation. A case report and a review of the literature. (3/315)
We report an unusual case of bilateral anterior shoulder dislocation following trauma. Previously reported cases were either of bilateral dislocations or bilateral fracture dislocations. In our case the patient suffered bilateral anterior dislocation with a three part fracture dislocation on the right. A review of the literature is presented. (+info)Involvement of 5-HT1B receptors in collar-induced hypersensitivity to 5-hydroxytryptamine of the rabbit carotid artery. (4/315)
In humans intimal thickening is aprerequisite of atherosclerosis. Application of a silicone collar around the rabbit carotid artery induces an intimal thickening but in addition it increases the sensitivity to the vasoconstrictor action of serotonin (5-hydroxytryptamine, 5-HT). The 5-HT receptors involved in collar-induced hypersensitivity to 5-HT were investigated using several agonists and antagonists. One week after placement of collars around both carotid arteries of anaesthetized rabbits, rings (2 mm width) from inside (=collar) and outside (=sham) the collars were mounted in organ baths (10 ml) for isometric force measurements at 6 g loading tension. Collared rings were more sensitive to the contractile effect of 5-HT (7.6 fold) and 5-carboxamidotryptamine (31 fold, 5-CT, 5-HT1 agonist) in cumulative concentration response curves. Sumatriptan (5-HT1B/1D agonist) caused concentration-dependent constrictions in collared rings only. Collar placement did not significantly alter pA2 values (Schild regression) or apparent pKb values (non-linear regression) of spiperone and methysergide (mixed 5-HT2A/5-HT1 antagonists) or ketanserin and ritanserin (5-HT2A antagonists), indicating unchanged binding characteristics of the 5-HT2A receptor. However, the reduced slope of the Schild regression pointed to a heterogeneous receptor population in collared rings. In contrast, the apparent pKb value of methiothepin (5-HT1B antagonist) was significantly reduced by collar placement, and its antagonism shifted from non-surmountable in sham rings to surmountable in collared segments. Taken together, this study demonstrates that the serotonergic receptor involved in the hypersensitivity to 5-HT of rabbit collared carotid artery is a 5-HT1B receptor subtype. (+info)Halo femoral traction and sliding rods in the treatment of a neurologically compromised congenital scoliosis: technique. (5/315)
In severe congenital scoliosis, traction (whether with a halo or instrumental) is known to expose patients to neurologic complications. However, patients with restrictive lung disease may benefit from halo traction during the course of the surgical treatment. The goal of treatment of such deformities is, therefore, twofold: improvement of the respiratory function and avoidance of any neurologic complications. We report our technique to treat a 17-year-old girl with a multi-operated congenital scoliosis of 145 degrees and cor pulmonale. Pre-operative halo gravity traction improved her vital capacity from 560 c.c. to 700 c.c., but led to mild neurologic symptoms (clonus in the legs). To avoid further neurologic compromise, her first surgery consisted of posterior osteotomies and the implantation of two sliding rods connected to loose dominoes without any attempt at correction. Correction was then achieved over a 3-week period with a halofemoral traction. This allowed the two rods to slide while the neurologic status of the patient was monitored. Her definitive surgery consisted of locking the dominoes and the application of a contralateral rod. Satisfactory outcome was achieved for both correction of the deformity (without neurologic sequels) and improvement of her pulmonary function (1200 c.c. at 2 years). This technique using sliding rods in combination with halofemoral traction can be useful in high-risk, very severe congenital scoliosis. (+info)Change of bone mineral density with valgus knee bracing. (6/315)
We assessed the clinical knee score and bone mineral density of the proximal tibia in an attempt to evaluate the efficacy of valgus knee bracing. The knee score improved after 3 months, and increases in bone mineral density were seen more in the lateral tibial condyle than in the medial. These results suggest that the brace acts by transferring the forces across the knee joint from the medial to the lateral side. (+info)Arthroscopic reconstruction of the anterior cruciate ligament with patellar-tendon autograft and interference screw fixation. The results at seven years. (7/315)
Deficiency of the anterior cruciate ligament (ACL) is a common disorder which can lead to changes in lifestyle. We followed 59 patients who had had arthroscopic reconstruction of the ACL using a central-third patellar-tendon autograft for seven years to assess the long-term effectiveness of recent advances in reconstruction of the ACL. The standard criteria for evaluation of the International Knee Documentation Committee, the Lysholm knee score and measurements using the KT 1000 arthrometer all showed satisfactory results. Deterioration in the clinical performance after seven years was associated with osteoarthritic changes and correlated with chronic ligament injuries and meniscectomy. There were three traumatic and three spontaneous ruptures. We believe that the procedure can be successful, but remain concerned about failure of the graft and osteoarthritis. The results raise questions about the best time to operate and suggest that early surgery may reduce the risk of osteoarthritis. (+info)Does bracing affect self-image? A prospective study on 54 patients with adolescent idiopathic scoliosis. (8/315)
To evaluate the effect of brace treatment on self-image in patients with adolescent idiopathic scoliosis, 54 consecutive patients admitted for brace treatment were interviewed before bracing. A prevalidated questionnaire including the following five aspects of self-image was used: (1) body-image, (2) self-perception of skills and talents, (3) emotional well-being, (4) relations with family, and (5) relations with others. As a control group, the answers of 3465 normal school children were used. Forty-six patients participated in a follow-up interview 1.7 (range 0.8-3.0) years later. In addition, during the first interview, the scoliosis patients answered selected questions about their social circumstances and attitudes towards their forthcoming brace treatment. Grossly, the patient group lived in stable family conditions with a high percentage (40%) of fathers and/or mothers with an academic education or with a high employee status. The patients' relations with families were generally good. Nearly all believed that the brace would affect their posture, but only a few thought that wearing the brace would influence their growth. Two-thirds believed that it would be difficult to wear the brace, and often reflected on the use of it. There were no statistically significant differences between the scoliosis patients and the age-matched controls at the pre-bracing nor at the follow-up interviews. Neither were there any statistically significant differences between the answers of the scoliosis patients in the pre-bracing and follow-up interviews. This was valid for the total score as well as for each subscale item score. It is concluded that wearing the brace does not affect the self-image of adolescents with idiopathic scoliosis negatively. (+info)In the field of dentistry, braces are devices used to align and straighten teeth and improve jaw position. They are typically made of metal or ceramic brackets that are bonded to the teeth, along with wires and rubber bands that apply pressure and move the teeth into proper alignment over time. The length of treatment with braces can vary but typically lasts from 1-3 years. Regular adjustments are necessary to ensure effective movement of the teeth.
The purpose of wearing braces is to correct malocclusions, such as overbites, underbites, crossbites, and open bites, as well as crowded or crooked teeth. This can lead to improved dental health, better oral function, and a more aesthetically pleasing smile. It's important to maintain good oral hygiene while wearing braces to prevent issues like tooth decay and gum disease. After the braces are removed, retainers may be used to maintain the new alignment of the teeth.
Scoliosis is a medical condition characterized by an abnormal lateral curvature of the spine, which most often occurs in the thoracic or lumbar regions. The curvature can be "C" or "S" shaped and may also include rotation of the vertebrae. Mild scoliosis doesn't typically cause problems, but severe cases can interfere with breathing and other bodily functions.
The exact cause of most scoliosis is unknown, but it may be related to genetic factors. It often develops in the pre-teen or teenage years, particularly in girls, and is more commonly found in individuals with certain neuromuscular disorders such as cerebral palsy and muscular dystrophy.
Treatment for scoliosis depends on the severity of the curve, its location, and the age and expected growth of the individual. Mild cases may only require regular monitoring to ensure the curve doesn't worsen. More severe cases may require bracing or surgery to correct the curvature and prevent it from getting worse.
Ankle injuries refer to damages or traumas that occur in the ankle joint and its surrounding structures, including bones, ligaments, tendons, and muscles. The ankle joint is a complex structure composed of three bones: the tibia (shinbone), fibula (lower leg bone), and talus (a bone in the foot). These bones are held together by various strong ligaments that provide stability and enable proper movement.
There are several types of ankle injuries, with the most common being sprains, strains, and fractures:
1. Ankle Sprain: A sprain occurs when the ligaments surrounding the ankle joint get stretched or torn due to sudden twisting, rolling, or forced movements. The severity of a sprain can range from mild (grade 1) to severe (grade 3), with partial or complete tearing of the ligament(s).
2. Ankle Strain: A strain is an injury to the muscles or tendons surrounding the ankle joint, often caused by overuse, excessive force, or awkward positioning. This results in pain, swelling, and difficulty moving the ankle.
3. Ankle Fracture: A fracture occurs when one or more bones in the ankle joint break due to high-impact trauma, such as a fall, sports injury, or vehicle accident. Fractures can vary in severity, from small cracks to complete breaks that may require surgery and immobilization for proper healing.
Symptoms of ankle injuries typically include pain, swelling, bruising, tenderness, and difficulty walking or bearing weight on the affected ankle. Immediate medical attention is necessary for severe injuries, such as fractures, dislocations, or significant ligament tears, to ensure appropriate diagnosis and treatment. Treatment options may include rest, ice, compression, elevation (RICE), immobilization with a brace or cast, physical therapy, medication, or surgery, depending on the type and severity of the injury.
Neoprene is not a medical term, but it is a material that is used in some medical applications. Neoprene is a type of synthetic rubber that is known for its flexibility, durability, and resistance to heat, water, and chemicals. It is often used in the manufacture of medical devices such as braces, supports, and protective gear.
In medical terms, neoprene may be referred to as a component of a device or material used in medical applications. For example, a neoprene sleeve may be used as a compression garment for venous insufficiency or lymphedema management. Neoprene is also sometimes used in the manufacture of medical gloves and other protective equipment due to its resistance to chemicals and other substances.
However, it's important to note that some people may have allergic reactions to neoprene, causing skin irritation or other symptoms. Therefore, healthcare providers should consider patients' individual needs and potential allergies when selecting medical devices made of neoprene or other materials.
Surgical casts are medical devices used to immobilize and protect injured body parts, typically fractured or broken bones, during the healing process. They are usually made of plaster or fiberglass materials that harden when wet and conform to the shape of the affected area once applied. The purpose of a surgical cast is to restrict movement and provide stability to the injured site, allowing for proper alignment and healing of the bones.
The casting process involves first aligning the broken bone fragments into their correct positions, often through manual manipulation or surgical intervention. Once aligned, the cast material is applied in layers, with each layer being allowed to dry before adding the next. This creates a rigid structure that encases and supports the injured area. The cast must be kept dry during the healing process to prevent it from becoming weakened or damaged.
Surgical casts come in various shapes and sizes depending on the location and severity of the injury. They may also include additional components such as padding, Velcro straps, or window openings to allow for regular monitoring of the skin and underlying tissue. In some cases, removable splints or functional braces may be used instead of traditional casts, providing similar support while allowing for limited movement and easier adjustments.
It is essential to follow proper care instructions when wearing a surgical cast, including elevating the injured limb, avoiding excessive weight-bearing, and monitoring for signs of complications such as swelling, numbness, or infection. Regular check-ups with a healthcare provider are necessary to ensure proper healing and adjust the cast if needed.
Orthotic devices are custom-made or prefabricated appliances designed to align, support, prevent deformity, or improve the function of movable body parts. They are frequently used in the treatment of various musculoskeletal disorders, such as foot and ankle conditions, knee problems, spinal alignment issues, and hand or wrist ailments. These devices can be adjustable or non-adjustable and are typically made from materials like plastic, metal, leather, or fabric. They work by redistributing forces across joints, correcting alignment, preventing unwanted movements, or accommodating existing deformities. Examples of orthotic devices include ankle-foot orthoses, knee braces, back braces, wrist splints, and custom-made foot insoles.
Lordosis is a term used in the medical field to describe an excessive inward curvature of the spine. It most commonly occurs in the cervical (neck) and lumbar (lower back) regions. When it happens in the lower back, it's often referred to as swayback. While some degree of lordosis is normal and necessary for proper spinal alignment and movement, excessive curvature can lead to pain, discomfort, and difficulty with mobility. It can be caused by a variety of factors, including poor posture, obesity, pregnancy, and certain medical conditions such as kyphosis or spondylolisthesis.
A sprain is a type of injury that occurs to the ligaments, which are the bands of tissue that connect two bones together in a joint. It's usually caused by a sudden twisting or wrenching movement that stretches or tears the ligament. The severity of a sprain can vary, from a minor stretch to a complete tear of the ligament.
A strain, on the other hand, is an injury to a muscle or tendon, which is the tissue that connects muscle to bone. Strains typically occur when a muscle or tendon is stretched beyond its limit or is forced to contract too quickly. This can result in a partial or complete tear of the muscle fibers or tendon.
Both sprains and strains can cause pain, swelling, bruising, and difficulty moving the affected joint or muscle. The severity of these symptoms will depend on the extent of the injury. In general, sprains and strains are treated with rest, ice, compression, and elevation (RICE) to reduce pain and inflammation, followed by rehabilitation exercises to restore strength and mobility.
