Many conditions can affect your hand and wrist, including trauma that can result from receiving a blow to the wrist or hand. This trauma may cause a fracture or a dislocation in any of the bones of you hand or wrist. An orthopedic specialist may suggest a brace or cast to help the bone heal or physical therapy to help you regain strength.
Repetitive use injuries, such as carpal tunnel syndrome and tendonitis, or genetic conditions can affect your hand and wrist. Other conditions include carpal bossing, flexor tendon sheath infections, jersey finger, boutonniére deformity, swan neck deformity, mallet finger and trigger finger. Many of these finger conditions cause difficulty with straightening your finger or pointing it down.
