In Pedorthic biomechanical terms, hallux valgus is a subluxation of the first metatarsophalangeal joint with deviation of the great toe towards the second and accompanied by an enlargement of the medial first metatarsal head. Subluxation is a partial dislocation of a joint that is produced when motion is contrary to its plain of motion of exceeds the range of motion of the particular joint. Two large sesamoid bones are present beneath the first metatarsophalangealjoint within the tendons of the flexor hallucis brevis. With the developmentof hallux valgus, the 1st metatarsal head migrates medially and dorsally.The fibular sesamoid frequently rotates slightly dorsally, and is seen onthe AP film in profile. One of the procedures to determine hallux valgus is the use of radiographs. Here we look at the hallux abductus angle. This is the angle formed between the longitudinal bisections of the first metatarsal and the proximal phalanx. When we have an angle less than 15°, there is no sign of hallux valgus. If the angle is greater than 15°, there is a sign of hallux valgus. An angle of 45-50 ° is considered serious. The degree of displacement of the sesamoids and the level of osteoarthritic change within the first MTP joint should be considered as well. 1 If athletes were given less care and more thought, the doctors might come up with some original ideas on why illness persists, why injury doesn’t clear up. If more non-physicians – podiatrists and physiotherapists for instance – could be induced to lend their ideas and talents, we might see a completely new approach to sports medicine. If the athlete had to wait longer for surgery, he might have time to recover from his ailments. ” I have a curse. It’s not rare, it’s not life-threatening, but it is a curse. Some days it hobbles me more than others, and I have to gingerly mince my way around. Bunions are bony growths that develop on the joint where the big toe meets the foot. As the bunion grows, increasing pressure forces the big toe joint outward, causing the big toe to point in and crowd other toes on the same foot. The result is pain when walking and wearing shoes. Structural defects and wearing tight shoes are the most common causes of bunions. Treatment focuses on relieving pain, reducing pressure and removing the bunion surgically when necessary. Step 1 A subluxation of the 1st MPJ with a deviation of the great toe towards the second with an enlargement of the medial first metatarsal head. OA can affect any of your joints in the feet but most likely to affect the joint at the base of the big toes. This joint is more prone to wear and tear from the pressures of walking, especially if you roll your foot in excessively as you walk. Wear and tear at the ends of the bone cause the cartilage to erode and the bone ends may begin to join together. Eventually your big toe may become rigid (a condition called hallux rigidus) which makes walking difficult. Or your big toe may drift towards your other toes ( hallux valgus ) which may cause bunions. Hallux valgus deformity – This deformity is defined as a lateral deviation of the hallux (great toe) on the first metatarsal ( figure 4 ). The deviation of the hallux occurs primarily in the transverse plane. The deformity often also involves rotation of the toe in the frontal plane causing the nail to face medially (ie, eversion). These two deviations have led to the use of different terms to describe the deformity. In orthopedic texts, it is often called "hallux valgus" (HV) whereas many podiatry texts prefer the term "hallux abductovalgus (HAV)." The public is more familiar with the expression "bunion."
