Foot pain began affecting Donna's tennis game, and she was determined not to let it keep her from the sport she loved.
The 47-year-old avid tennis player from Arizona tried to play through the pain and rest her feet between matches. But when the pain became too much, and even started affecting her everyday activities, she made an appointment with a foot and ankle surgeon. His diagnosis: Donna was suffering from plantar fasciitis and a neuroma.
According to Donna's doctor, Kris DiNucci, DPM, FACFAS, a Fellow of the American College of Foot and Ankle Surgeons, the conditions plaguing her are common among court-playing athletes. "Because playing tennis requires quick, repetitive foot movements and continuous forefoot pressure, neuromas, (a thickening of the nerve tissue in the foot from compression) are common," DiNucci says. "In addition, those same movements can cause athletes to develop plantar fasciitis, an inflammation of the strong ligament that extends from the heel to the toes," he added. "If treated early, both conditions can be resolved non-operatively. But as the condition progresses, surgical methods may be required to help patients get back to their sport and their everyday activities."
Donna's treatment regimen included stretching exercises, icing, a cortisone injection, an adjustment to her shoes and custom orthotics. "Within four months the heel pain from the plantar fasciitis had improved tremendously. But the pain in the ball of my foot from the neuroma was still bad and Dr. DiNucci recommended surgery," Donna said.
"While surgery is not always needed to treat neuromas, in Donna's case it was necessary because she wasn't responding to non-surgical treatments," DiNucci said.
Four weeks after surgery, Donna was back on the tennis courts and eight-weeks post-op, she was back to her normal three-to-four day a week tennis game.
Court-playing athletes, such as tennis and basketball players, are also susceptible to Achilles tendonitis, sesamoiditis, stress fractures, ankle sprains and posterior tibial tendonitis, which all can be brought on from the high-impact movements of playing on hard surfaces. "Players with existing foot maladies or structural abnormalities of the lower extremity also need to be extra cautious while playing since their conditions can put them at a higher risk for overuse injury," says Dr. DiNucci.
No matter the sport, athletes must take preventive methods to protect their feet to keep themselves in the game. Supportive shoes tailored to the sport are vital, along with proper training and stretching before and after play. If athletes are injured or experience pain or discomfort in their feet or ankles, it's best to be examined by a foot and ankle surgeon. Early intervention is the key to proper healing.
As for Donna, she's back on her feet and has made modifications to her game, such as stretching before and after a match and wearing more supportive shoes with her orthotics.

First Gene Linked To Scoliosis Identified By Scientists
Physicians have recognized scoliosis, the abnormal curvature of the spine, since the time of Hippocrates, but its causes have remained a mystery -- until now. For the first time, researchers have discovered a gene that underlies the condition, which affects about 3 percent of all children.
The new finding lays the groundwork for determining how a defect in the gene -- known as CHD7 -- leads to the C- and S-shaped curves that characterize scoliosis. The gene's link to scoliosis was identified by scientists at Washington University School of Medicine in St. Louis, working in collaboration with investigators at the University of Texas Southwestern Medical Center and Texas Scottish Rite Hospital for Children, both in Dallas, Rutgers State University of New Jersey and the University of Iowa. The group published its results in May in the American Journal of Human Genetics.
"Hopefully, we can now begin to understand the steps by which the gene affects spinal development," says Anne Bowcock, Ph.D., professor of genetics, of medicine and of pediatrics. "If we understand the genetic basis of the condition, we can theoretically predict who is going to develop scoliosis and develop treatments to intervene before the deformity sets in. It may take many years to accomplish these goals, but I think it will eventually happen."
The researchers have traced a defect in CHD7 to idiopathic scoliosis, the form of the condition for which there is no apparent cause. It is the most common type of scoliosis, occurs in otherwise healthy children and is typically detected during the growth spurt that accompanies adolescence.
Although scientists have known for years that scoliosis runs in families, its pattern of inheritance has remained unclear. That's because the condition is likely caused by several different genes that work in concert with one another -- and the environment -- to cause scoliosis. Bowcock predicts that scientists will soon find other genes involved in the disease.
The CHD7 gene is thought to play a critical role in many basic functions in the cell. The researchers zeroed in on the gene after finding that it is missing or profoundly disrupted in a rare syndrome called CHARGE. Babies born with the syndrome often die in infancy. Those that survive have heart defects, mental retardation, genital and urinary problems, ear abnormalities and deafness, among other problems. They also develop late-onset scoliosis.
"This led us to consider that milder variations of CHD7 may be involved in other types of scoliosis," Bowcock said.
The researchers, led by Carol Wise, Ph.D., at Scottish Rite Hospital, collected data on 52 families with a history of scoliosis in at least two members -- the one who sought treatment and another from earlier generation. The patients had an average spinal curvature of 40 degrees and did not have any illnesses, such as Marfan syndrome or cerebral palsy, which can also involve scoliosis. The researchers performed genome-wide scans that spelled out the 6 billion letters of genetic code in the affected family members and analyzed the data.
They found that patients with scoliosis very often had a defect in the gene's non-coding region, meaning that the error did not disrupt production of the CHD7 protein. The researchers speculate that this particular mutation alters the binding of a molecule that controls whether the gene is turned on. In this case, they think the gene is turned off more often than it should be, which reduces the amount of CHD7 protein produced.
"The change in the amount of the protein produced is subtle, which correlates with the onset of scoliosis, which typically happens very gradually," explains Michael Lovett, Ph.D., professor of genetics and pediatrics. "This particular defect was so highly associated with scoliosis that it is either the real McCoy or is very closely linked to the defect that causes the condition."
The researchers will continue to look for genetic variations involved in scoliosis by studying additional families with the condition.
Severe scoliosis is typically treated by surgery or by wearing an orthopedic brace, which straightens the curvature over time. Most minor spinal curves can be monitored by a doctor and do not progress to the point where treatment is necessary.

Advances In The Treatment Of Hand And Wrist Injuries And Disorders
An injury or ailment involving your hand or wrist can severely limit your ability to perform daily activities, such as taking a shower, driving a car or using a computer, and requires an expert team of physicians, surgeons and physical and occupational therapists. The physicians of the Penn Hand Service, part of the Penn Orthopaedic Institute , provide comprehensive treatment for a wide range of issues, including arthritis, fractures, nerve problems and sports-related injuries.
As medical advances in arthroscopy and imaging techniques are used more frequently to evaluate the small bones and ligaments of the hand, the physicians of the Penn Hand Service are exploring how these advances can improve the diagnosis and treatment of hand and wrist injuries.
New Treatment Option for a Broken Wrist
A distal radius fracture, or a broken wrist, is the most common break in the arm, according to the American Academy of Orthopaedic Surgeons, and usually results from some type of trauma, such as a fall or an accident. Since older patients are prone to weak bones due to osteoporosis, this type of fracture is more difficult to repair in the older population.
The orthopaedic surgeons at the Penn Hand Service are developing new instruments and devices, such as a combination of stainless steel pins and plates, which will make it easier to repair more difficult fractures, particularly in the elderly.
"In the past, some surgeons may have used external fixation, which involves placing pins or screws into the bone on both sides of the fracture, and securing them outside the skin with clamps and rods. But we've found that internal fixation, using plates in particular, allows us to align the bones better, and patients are able to regain mobility faster," says David Steinberg, MD, associate professor of orthopaedic surgery at the University of Pennsylvania Health System.
Wrist Arthroscopy
With its small incisions, arthroscopy is increasingly being used in the treatment of the hand. Arthroscopy is a technique used to evaluate a joint for damage or disease and, if necessary, to perform surgery. Wrist arthroscopy, in particular, has proven to be extremely valuable both in diagnosis and therapy. "It is very helpful for arthritis, for example," says David Bozentka, MD, chief of the department of orthopaedic surgery at Penn Presbyterian Medical Center. "We can assess the ligaments of the wrist and examine the extent of injury, all without making any large incisions."
Penn surgeons are also using this arthroscopic technique to treat ligament injuries in the wrist and to evaluate small joints in the hand. "We've even treated some cases of basal joint arthritis (arthritis in the joint at the base of the thumb) with arthroscopy," says Dr. Steinberg.
Wrist arthroscopy is a minimally invasive surgery, which typically limits patient discomfort and allows for faster recovery. In general, the procedure is appropriate for patients with earlier stage arthritis or torn cartilage, which is better suited to this type of treatment.
"Advanced cases of arthritis, for example, require more cleaning out of bone and, in some cases, ligament reconstruction, which is better performed through open surgery," says Dr. Steinberg. Nevertheless, arthroscopy remains a good surgical option for a number of conditions, which at one time required a larger incision in the wrist.

Emisphere Announces Recruitment Phase III Study For Oral Osteoarthritis Treatment
Emisphere
Technologies, Inc. (Nasdaq: EMIS) announced that Novartis Pharma AG
and Nordic Bioscience have completed recruitment for a multi-center Phase
III study exploring the safety and efficacy of an oral formulation of
salmon calcitonin using Emisphere's proprietary Eligen Technology to treat
patients with osteoarthritis of the knee. This study, which will be used to
support the filing with health authorities worldwide, includes more than
1,100 patients between 51 and 80 years old with a medical history and
symptoms of knee osteoarthritis. The study will be conducted mainly in
Europe and is estimated to complete second half 2010.
Osteoarthritis ("OA") is a clinical syndrome in which low-grade
inflammation results in joint pain, caused by a wearing-away of cartilage
that cushions the joints and the destruction or decrease of synovial fluid
that lubricates those joints. As OA progresses, pain can result when the
patient bears weight upon the joints, including walking and standing. OA is
the most common form of arthritis, and affects nearly 21 million people in
the United States, accounting for 25% of visits to primary care physicians,
and half of all non-steroidal anti-inflammatory drug prescriptions. It is
estimated that 80% of the population will have radiographic evidence of OA
by age 65.
"The problems associated with osteoarthritis will escalate as the
population ages," said Michael V. Novinski, President and Chief Executive
Officer of Emisphere. "This Phase III study aims at demonstrating that oral
salmon calcitonin, in combination with our Eligen drug delivery technology,
may contribute to solving this problem, and also shows that Emisphere is a
valuable partner in drug development."
About Emisphere Technologies, Inc.
Emisphere is a biopharmaceutical company that focuses on a unique and
improved delivery of therapeutic molecules using its Eligen Technology.
These molecules and compounds could be currently available or in
development. Such molecules are usually delivered by injection; in many
cases, their benefits are limited due to poor bioavailability, slow on-set
of action or variable absorption. The Eligen Technology can be applied to

Top Children's Surgeon Says 'Poverty' Bone Disease Has Returned In Southampton
A poverty-linked bone disease that disappeared over 80 years ago, but resurfaced in northern parts of the UK this year, is now being discovered in high numbers of young patients in Southampton.
Rickets, a condition that causes children's bones to become weak and bowed, was endemic in poor Victorian England, but was written off by many orthopaedic surgeons by 1928 following the discovery of vitamin D in 1922.
However, the disease is now making a comeback around the world due to low vitamin D levels caused predominantly by lack of exposure to sunlight and also poor diet - though it had not been uncovered in Southampton until now.
This vitamin, found in a small number of foods, is important in supporting growth and maintaining strong bones.
"The return of rickets in northern parts of the UK came as a surprise despite the colder climate and lower levels of sunshine in the north, but what has developed in Southampton is quite astonishing," said Professor Nicholas Clarke, consultant orthopaedic surgeon at Southampton General Hospital and professor of paediatric orthopaedic surgery at the University of Southampton.
He explains that despite being historically linked with poverty-stricken communities, rickets is now appearing in children from all backgrounds.
"In my 22 years at Southampton General Hospital, this is a completely new occurrence in the south that has evolved over the last 12 to 24 months and we are seeing cases across the board, from areas of deprivation up to the middle classes, so there is a real need to get national attention focused on the dangers this presents."
Professor Clarke says he and colleague Dr Justin Davies, a consultant paediatric endocrinologist, have checked over 200 children for bone problems and more than 20% of them have significant deficiencies.
"A lot of the children we've seen have got low vitamin D and require treatment," he said.
"This is almost certainly a combination of the modern lifestyle, which involves a lack of exposure to sunlight, but also covering up in sunshine, and we're seeing cases that are very reminiscent of 17th century England."
He added: "We are facing the daunting prospect of an area like Southampton, where it is high income, middle class and leafy in its surroundings, seeing increasing numbers of children with rickets, which would have been inconceivable only a year or so ago."
Professor Clarke says vitamin D supplements should be more widely adopted to halt the rise in cases.

He explains that despite being historically linked with poverty-stricken communities, rickets is now appearing in children from all backgrounds.
"In my 22 years at Southampton General Hospital, this is a completely new occurrence in the south that has evolved over the last 12 to 24 months and we are seeing cases across the board, from areas of deprivation up to the middle classes, so there is a real need to get national attention focused on the dangers this presents."
Professor Clarke says he and colleague Dr Justin Davies, a consultant paediatric endocrinologist, have checked over 200 children for bone problems and more than 20% of them have significant deficiencies.
"A lot of the children we've seen have got low vitamin D and require treatment," he said.
"This is almost certainly a combination of the modern lifestyle, which involves a lack of exposure to sunlight, but also covering up in sunshine, and we're seeing cases that are very reminiscent of 17th century England."
He added: "We are facing the daunting prospect of an area like Southampton, where it is high income, middle class and leafy in its surroundings, seeing increasing numbers of children with rickets, which would have been inconceivable only a year or so ago."
Professor Clarke says vitamin D supplements should be more widely adopted to halt the rise in cases.

1-Stop Screening For Cancer And Osteoporosis
New research reveals that computed tomography (CT) colonography, also known as virtual colonoscopy, has the potential to screen for two diseases at once - colorectal cancer and osteoporosis, both of which commonly affect adults over age 50. Results of the study will be presented today at the annual meeting of the Radiological Society of North America (RSNA).
"With CT colonography, in addition to screening for colorectal cancer, we were able to identify patients with osteoporosis," said lead author Rizwan Aslam, M.B.Ch.B., assistant clinical professor of radiology at the University of California San Francisco.
CT colonography, an imaging study performed to detect pre-cancerous polyps in the large intestine, begins with an abdominal CT scan, which creates cross-sectional images of all structures in the abdomen including the spine. Computer software then arranges the CT images to create an interior or "fly-through" view of the colon.
Using the same CT images, another software application can create three-dimensional images of the spine, allowing bone mineral density to be measured. Low bone mineral density is usually associated with osteoporosis, a disease in which bones become fragile and more likely to break.
In the study conducted at the San Francisco Veterans Administration Hospital, the researchers evaluated the results of 35 patients who underwent CT colonography and bone mineral density testing with dual-energy x-ray absorptiometry (DEXA), a standard bone density screening tool. Patients included 30 males and five females ranging in age from 54 to 79.
The results of the study showed excellent agreement between the DEXA bone mineral density scores and the data generated through the CT colonography study.
"The bone density measurements obtained from CT colonography were comparable to the DEXA results," Dr. Aslam said. "Both tests identified osteoporotic bones."
Most physicians recommend that adults undergo CT colonography or conventional colonoscopy every seven to 10 years beginning at age 50.
"CT colonography isn't a replacement for DEXA testing, but it could be a way to screen more people for osteoporosis," Dr. Aslam said. "When an individual undergoes CT colonography, we can also obtain a bone density measurement with no additional radiation and at minimal cost."
According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, 10 million Americans over age 50 have osteoporosis. Approximately 34 million Americans are at risk due to low bone mass. Detecting osteoporosis early provides for early intervention and treatment.
