A team of US orthopedic surgeons is visiting the Gaza Strip to perform a series of joint replacement operations and provide training to local doctors. Khaled Saleh, president of the US-based non-profit Fajr Scientific, said the visit would help patients immobilized by joint problems and chronic pain, as well as those in wheelchairs or who use a cane to walk. The five-day mission aimed to operate on 150 patients, train local surgeons, and donate $4 million worth of vital equipment.
