Distal arthrogryposis type 1 is a disorder characterised by joint deformities (contractures) that restrict movement in the hands and feet. The term "arthrogryposis" comes from the Greek words for joint (arthro-) and crooked or hooked (gryposis). The characteristic features of this condition include permanently bent fingers and toes (camptodactyly), overlapping fingers, and a hand deformity in which all of the fingers are angled outward toward the fifth finger (ulnar deviation). Clubfoot, which is an inward- and upward-turning foot, is also commonly seen with distal arthrogryposis type 1. The specific hand and foot abnormalities vary among affected individuals. However, this condition typically does not cause any signs and symptoms affecting other parts of the body.

Pneumococcal immunisation
Pneumococcus can cause diseases such as pneumonia, meningitis and blood infections. Children aged under 2 years should receive the vaccine. You should consider pneumococcal immunisation if you are aged over 65 years or have certain diseases of the lung, heart, kidney, liver and nervous system. Pneumonia vaccine side-effects are mild, and many.
