19 October marks the World Pediatric Bone and Joint Day, also knows as World PB & J Day. The day is observed during the Bone and Joint Action Week, which also includes World Arthritis Day, World Spine Day, World Trauma Day and World Osteoporosis Day.
It was initiated by the United States Bone and Joint Initiative in 2012, to improve the prevention of bone and joint disorders, and the quality of life for those affected. The day aims to bring awareness about musculoskeletal conditions of children, and educate healthcare providers and the public about them  , also urging the doctors and parents to recognize the effects of obesity in children and take actions - thereby, avoiding the possibilities of lifelong challenges.
The current theme has not been published yet, but the past themes have included obesity, obesity and the growth plate, vitamin D deficiency, the female athlete triad, and ACL injuries. One of the primary focuses of the day is the topic of obesity during childhood, which plays a major role in bone and joint health 
Today, we will take a look at the different types of bone and joint problems affecting children.
Bone And Joint Problems In Children
Disorders related to bone and joints in children can be caused by infection, injury or it can be inherited and develop as a part of a child's growth, or occur for no known reason at all. Some bone disorders can cause pain and difficulty, while they do not pose any symptoms  .

Types Of Bone And Joint Problems In Children
Septic arthritis (joint infection): infectious arthritis is one of the common infections affecting a child's joints. The infection usually reaches the joints through the bloodstream and is an intensely painful infection and causes redness, heat and pain in a single joint associated with a decreased ability to move the joint. The condition needs immediate medical attention  .
The condition is diagnosed through ultrasonography and is treated using a needle aspiration of the affected joint, surgical drainage, and intravenous or oral use of antibiotics.
Osteomyelitis (bone infection): A bacterial infection affecting the bone, osteomyelitis affects the long bones of the arms and legs. It is common can be treated with intravenous or oral use of antibiotics. A rare but serious condition, the infection can reach the bones through various ways like it may spread through the bloodstream into the bone, or an open fracture or surgery may expose the bone to infection  .
Post streptococcal reactive arthritis (PSRA): A type of arthritis, PSRA is of acute onset, symmetric or asymmetric and is non-migratory.

- Needle aspiration
- Bone scan
- Blood test
- Tissue culture
- Imaging tests such as x-rays, magnetic resonance imaging (MRI) scans, and ultrasound
Treatment For Bone And Joint Problems In Children
