An x-ray study of valgus ankles in spina bifida children with valgus flat foot deformity. (1/66)
Radiological examination of the ankles of spina bifida children with flail lower limbs and valgus flat foot deformity has revealed a high incidence of abnormal valgus tilt of the ankle-joint. A study of ankle X-rays of spina bifida children before and after extra-articular subtalar fusion in which the bone graft is removed from the ipsilateral tibia has shown that the valgus tilt of the mortice may increase after this procedure. (+info)A new look at osteogenesis imperfecta. A clinical, radiological and biochemical study of forty-two patients. (2/66)
In a clinical, radiological and biochemical study of forty-two patients from Oxford with osteogenesis imperfecta, it was found that patients could be divided simply into mild, moderate and severe groups according to deformity of long bones. In the severe group (seventeen patients) a family history of affected members was uncommon and fractures began earlier and were more frequent than in the mild group (twenty-two patients); sixteen patients in the severe group had scoliosis and eleven had white sclerae; no patients in the mild group had white sclerae or scoliosis. Radiological examination of the femur showed only minor modelling defects in patients in the mild group, whereas in the severe group five distinct appearances of bone (thin, thick, cystic and buttressed bones, and those with hyperplastic callus) were seen. The polymeric (structural) collagen from skin was unstable to depolymerisation in patients in the severe group, but normal in amount, whereas the reverse was found in the mild group. This division according to long bone deformity may provide, a basis for future research more useful than previous classifications. (+info)Flat foot. A preliminary report of an operation for severe cases. (3/66)
The pathogenesis of flat foot and its operative correction for severe cases are reviewed. The importance of the medial plantar fascia in maintaining the structural integrity of the foot is emphasised. Reinforcement of an incompetent plantar fascia by separating the inner half of the calcaneal tendon and attaching it to the neck of the first metatarsal has given results in three patients that were satisfactory at two, six and seven years later. (+info)Calcaneo-valgus deformity. (4/66)
A discussion of the essential deformity in calcaneo-valgus feet develops a theme originally put forward in 1961 on the relapsed club foot (Evans 1961). Whereas in the normal foot the medial and lateral columns are about equal in length, in talipes equino-varus the lateral column is longer and in calcaneo-valgus shorter than the medial column. The suggestion is that in the treatment of both deformities the length of the columns be made equal. A method is described of treating calcaneo-valgus deformity by inserting cortical bone grafts taken from the tibia to elongate the anterior end of the calcaneus. (+info)Calcaneal osteotomy and transfer of the tendon of flexor digitorum longus for stage-II dysfunction of tibialis posterior. Three- to five-year results. (5/66)
The treatment of acquired flat foot secondary to dysfunction of the posterior tibial tendon (PTT) of stage II, as classified by Johnson and Strom, remains controversial. Joint sparing and soft-tissue reconstructive procedures give good early results, but few studies describe those in the medium-term. We studied prospectively the outcome of surgery in 51 patients with classical stage-II dysfunction of the PTT treated by a medial displacement calcaneal osteotomy and transfer of the tendon of flexor digitorum longus. We reviewed 44 patients with a mean follow-up of 51 months (38 to 62). The mean American Orthopaedic Foot and Ankle Society ankle/hindfoot rating scale improved from 48.8 before operation to 88.5 at follow-up. The operation failed in two patients who later had a calcaneocuboid fusion. The outcome in 43 patients was rated as good to excellent for pain and function, and in 36 good to excellent for alignment. There were no poor results. (+info)Foot problems as risk factors of fractures. (6/66)
This case-control study examines whether foot problems are risk factors of fractures of five sites among people aged 45 years or older at six Kaiser Permanente Medical Centers in northern California. From October 1996 to May 2001, interviewers collected information through a standardized questionnaire. Incident cases of distal forearm (n = 1,000), foot (n = 827), proximal humerus (n = 448), shaft of the tibia/fibula (n = 168), and pelvis (n = 172) fractures and 1,913 controls from the same medical centers were included. After adjustment for potential confounders and for each additional foot problem, the odds of a foot fracture increased by 8% (adjusted odds ratio = 1.08, 95% confidence interval: 1.03, 1.13). In contrast, each additional foot problem was associated with a reduction in the odds of a forearm fracture (adjusted odds ratio = 0.93, 95% confidence interval: 0.89, 0.98). In general, foot problems were not related to fractures of other sites, although diabetes, which may result in foot problems, increased the odds of a proximal humerus fracture (adjusted odds ratio = 1.65, 95% confidence interval: 1.20, 2.26). If these findings are supported by data from other studies, preventive measures to retard the development of foot problems could reduce the incidence of foot fractures. (+info)A RADIOGRAPHIC ANALYSIS OF MAJOR FOOT DEFORMITIES. (7/66)
Major foot deformities were analyzed using standardized radiographic drawings of the foot in weight-bearing. Specific criteria and a classification of foot deformities by radiographic analysis are presented, utilizing "lining systems" related to the main bones of the hindfoot.The radiographic appearance of the foot is described and analyzed, as are the principal deformities such as varus and valgus heel and forefoot. The prefixes "talipes" and "pes" have been used to signify congenital and acquired deformities, respectively.Specific foot deformities, including talipes equinovarus (clubfoot), pes planovalgus (flatfoot), pes cavus, and metatarsus varus, are analyzed. This method can also be applied in the radiological analysis of any foot deformity.By using this technique, a brief, concise and simplified analysis of foot deformities is available to the student, general practitioner, and specialist. (+info)The relationship between the flexible flatfoot and plantar fasciitis: ultrasonographic evaluation. (8/66)
BACKGROUND: The purpose of this study was to investigate the relationship between flexible flatfoot and plantar fasciitis. METHODS: Twenty-three subjects with flexible flatfoot and 23 subjects with normal arched feet were enrolled. Footprint analysis was used to evaluate the foot conditions in both groups to calculate the individual arch index. We compared the sonographic images of plantar fascia in the flexible flatfoot group with the normal arch group using high-frequency ultrasound. RESULTS: The analysis results indicated that the thickening of the plantar fascia in the flexible flatfoot group was significantly different from the normal arch group. In the flexible flatfoot group, 10 of 23 patients (43.4%) had plantar fasciitis, but only two subjects (8.7%) in the normal arch group had plantar fasciitis. CONCLUSIONS: There was a higher incidence of plantar fasciitis in the flexible flatfoot group than the normal arch control group in this study. (+info)Medical professionals define "flatfoot" or "pes planus" as a postural deformity in which the arch of the foot collapses, leading to the entire sole of the foot coming into complete or near-complete contact with the ground. This condition can be classified as flexible (the arch reappears when the foot is not bearing weight) or rigid (the arch does not reappear). Flatfoot can result from various factors such as genetics, injury, aging, or certain medical conditions like rheumatoid arthritis and cerebral palsy. In some cases, flatfoot may not cause any symptoms or problems; however, in other instances, it can lead to pain, discomfort, or difficulty walking. Treatment options for flatfoot depend on the severity of the condition and associated symptoms and may include physical therapy, orthotics, bracing, or surgery.
The tarsal bones are a group of seven articulating bones in the foot that make up the posterior portion of the foot, located between the talus bone of the leg and the metatarsal bones of the forefoot. They play a crucial role in supporting the body's weight and facilitating movement.
There are three categories of tarsal bones:
1. Proximal row: This includes the talus, calcaneus (heel bone), and navicular bones. The talus articulates with the tibia and fibula to form the ankle joint, while the calcaneus is the largest tarsal bone and forms the heel. The navicular bone is located between the talus and the cuneiform bones.
2. Intermediate row: This includes the cuboid bone, which is located laterally (on the outside) to the navicular bone and articulates with the calcaneus, fourth and fifth metatarsals, and the cuneiform bones.
3. Distal row: This includes three cuneiform bones - the medial, intermediate, and lateral cuneiforms - which are located between the navicular bone proximally and the first, second, and third metatarsal bones distally. The medial cuneiform is the largest of the three and articulates with the navicular bone, first metatarsal, and the intermediate cuneiform. The intermediate cuneiform articulates with the medial and lateral cuneiforms and the second metatarsal. The lateral cuneiform articulates with the intermediate cuneiform, cuboid, and fourth metatarsal.
Together, these bones form a complex network of joints that allow for movement and stability in the foot. Injuries or disorders affecting the tarsal bones can result in pain, stiffness, and difficulty walking.
Posterior Tibial Tendon Dysfunction (PTTD) is a condition that affects the posterior tibial tendon, which runs along the inside of the ankle and helps to support the arch of the foot. In PTTD, the tendon becomes inflamed, stretched or torn, leading to instability and sometimes flatfoot deformity.
The medical definition of PTTD is:
A progressive degenerative condition of the posterior tibial tendon, resulting in loss of its function as a stabilizer and support for the arch of the foot. This can lead to acquired flatfoot deformity, characterized by pain, swelling, and weakness along the inside of the ankle and foot. In advanced stages, the condition may cause difficulty walking or standing for prolonged periods, and may require surgical intervention.
Foot deformities refer to abnormal changes in the structure and/or alignment of the bones, joints, muscles, ligaments, or tendons in the foot, leading to a deviation from the normal shape and function of the foot. These deformities can occur in various parts of the foot, such as the toes, arch, heel, or ankle, and can result in pain, difficulty walking, and reduced mobility. Some common examples of foot deformities include:
1. Hammertoes: A deformity where the toe bends downward at the middle joint, resembling a hammer.
2. Mallet toes: A condition where the end joint of the toe is bent downward, creating a mallet-like shape.
3. Claw toes: A combination of both hammertoes and mallet toes, causing all three joints in the toe to bend abnormally.
4. Bunions: A bony bump that forms on the inside of the foot at the base of the big toe, caused by the misalignment of the big toe joint.
5. Tailor's bunion (bunionette): A similar condition to a bunion but occurring on the outside of the foot, at the base of the little toe.
6. Flat feet (pes planus): A condition where the arch of the foot collapses, causing the entire sole of the foot to come into contact with the ground when standing or walking.
7. High arches (pes cavus): An excessively high arch that doesn't provide enough shock absorption and can lead to pain and instability.
8. Cavus foot: A condition characterized by a very high arch and tight heel cord, often leading to an imbalance in the foot structure and increased risk of ankle injuries.
9. Haglund's deformity: A bony enlargement on the back of the heel, which can cause pain and irritation when wearing shoes.
10. Charcot foot: A severe deformity that occurs due to nerve damage in the foot, leading to weakened bones, joint dislocations, and foot collapse.
Foot deformities can be congenital (present at birth) or acquired (develop later in life) due to various factors such as injury, illness, poor footwear, or abnormal biomechanics. Proper diagnosis, treatment, and management are essential for maintaining foot health and preventing further complications.
The calcaneus is the largest tarsal bone in the human foot, and it is commonly known as the heel bone. It articulates with the cuboid bone anteriorly, the talus bone superiorly, and several tendons and ligaments that help to form the posterior portion of the foot's skeletal structure. The calcaneus plays a crucial role in weight-bearing and movement, as it forms the lower part of the leg's ankle joint and helps to absorb shock during walking or running.
The metatarsal bones are a group of five long bones in the foot that connect the tarsal bones in the hindfoot to the phalanges in the forefoot. They are located between the tarsal and phalangeal bones and are responsible for forming the arch of the foot and transmitting weight-bearing forces during walking and running. The metatarsal bones are numbered 1 to 5, with the first metatarsal being the shortest and thickest, and the fifth metatarsal being the longest and thinnest. Each metatarsal bone has a base, shaft, and head, and they articulate with each other and with the surrounding bones through joints. Any injury or disorder affecting the metatarsal bones can cause pain and difficulty in walking or standing.
Acquired foot deformities refer to structural abnormalities of the foot that develop after birth, as opposed to congenital foot deformities which are present at birth. These deformities can result from various factors such as trauma, injury, infection, neurological conditions, or complications from a medical condition like diabetes or arthritis.
Examples of acquired foot deformities include:
1. Hammertoe - A deformity where the toe bends downward at the middle joint, resembling a hammer.
2. Claw toe - A more severe form of hammertoe where the toe also curls under, forming a claw-like shape.
3. Mallet toe - A condition where the end joint of a toe is bent downward, causing it to resemble a mallet.
4. Bunions - A bony bump that forms on the inside of the foot at the big toe joint, often causing pain and difficulty wearing shoes.
5. Tailor's bunion (bunionette) - A similar condition to a bunion, but it occurs on the outside of the foot near the little toe joint.
6. Charcot foot - A severe deformity that can occur in people with diabetes or other neurological conditions, characterized by the collapse and dislocation of joints in the foot.
7. Cavus foot - A condition where the arch of the foot is excessively high, causing instability and increasing the risk of ankle injuries.
8. Flatfoot (pes planus) - A deformity where the arch of the foot collapses, leading to pain and difficulty walking.
9. Pronation deformities - Abnormal rotation or tilting of the foot, often causing instability and increasing the risk of injury.
Treatment for acquired foot deformities varies depending on the severity and underlying cause but may include orthotics, physical therapy, medication, or surgery.
Plantar fasciitis is a medical condition that involves inflammation of the plantar fascia, which is a thick band of tissue that runs along the bottom of your foot, connecting your heel bone to your toes. This tissue supports the arch of your foot and absorbs shock when you walk or run.
Plantar fasciitis is often caused by repetitive stress or overuse, leading to small tears and inflammation in the fascia. People who have high arches or flat feet, those who spend a lot of time on their feet, and athletes who engage in activities that put repeated stress on the heel and attached tissue, such as runners, are at a higher risk of developing plantar fasciitis.
Symptoms of plantar fasciitis include pain and stiffness in the heel or bottom of the foot, especially when taking the first few steps after getting out of bed or after prolonged periods of sitting or standing. The pain may worsen over time if left untreated, making it difficult to walk, climb stairs, or participate in physical activities.
Treatment for plantar fasciitis typically includes rest, ice, compression, and elevation (RICE) therapy, as well as physical therapy exercises to stretch and strengthen the foot and lower leg muscles. In some cases, medication, orthotics, or even surgery may be necessary to alleviate severe pain and inflammation.
The talus is a bone in the foot that articulates with the tibia and fibula to form the ankle joint, also known as the talocrural joint. It is unique because it doesn't have any muscle attachments and gets its blood supply from surrounding vessels. Its main function is to transfer weight and force during movement from the lower leg to the foot.
"Foot joints" is a general term that refers to the various articulations or connections between the bones in the foot. There are several joints in the foot, including:
1. The ankle joint (tibiotalar joint): This is the joint between the tibia and fibula bones of the lower leg and the talus bone of the foot.
2. The subtalar joint (talocalcaneal joint): This is the joint between the talus bone and the calcaneus (heel) bone.
3. The calcaneocuboid joint: This is the joint between the calcaneus bone and the cuboid bone, which is one of the bones in the midfoot.
4. The tarsometatarsal joints (Lisfranc joint): These are the joints that connect the tarsal bones in the midfoot to the metatarsal bones in the forefoot.
5. The metatarsophalangeal joints: These are the joints between the metatarsal bones and the phalanges (toes) in the forefoot.
6. The interphalangeal joints: These are the joints between the phalanges within each toe.
Each of these foot joints plays a specific role in supporting the foot, absorbing shock, and allowing for movement and flexibility during walking and other activities.
Foot diseases refer to various medical conditions that affect the foot, including its structures such as the bones, joints, muscles, tendons, ligaments, blood vessels, and nerves. These conditions can cause symptoms like pain, swelling, numbness, difficulty walking, and skin changes. Examples of foot diseases include:
1. Plantar fasciitis: inflammation of the band of tissue that connects the heel bone to the toes.
2. Bunions: a bony bump that forms on the joint at the base of the big toe.
3. Hammertoe: a deformity in which the toe is bent at the middle joint, resembling a hammer.
4. Diabetic foot: a group of conditions that can occur in people with diabetes, including nerve damage, poor circulation, and increased risk of infection.
5. Athlete's foot: a fungal infection that affects the skin between the toes and on the soles of the feet.
6. Ingrown toenails: a condition where the corner or side of a toenail grows into the flesh of the toe.
7. Gout: a type of arthritis that causes sudden, severe attacks of pain, swelling, redness, and tenderness in the joints, often starting with the big toe.
8. Foot ulcers: open sores or wounds that can occur on the feet, especially in people with diabetes or poor circulation.
9. Morton's neuroma: a thickening of the tissue around a nerve between the toes, causing pain and numbness.
10. Osteoarthritis: wear and tear of the joints, leading to pain, stiffness, and reduced mobility.
Foot diseases can affect people of all ages and backgrounds, and some may be prevented or managed with proper foot care, hygiene, and appropriate medical treatment.
