Study Notes
Traumatic Causes of Hand Tendon Injuries
- Common causes include sports injuries, falls, cuts, and crush injuries.
- Frequently associated with high-impact activities or accidents.
Spontaneous Tendon Tears
- Often linked with systemic inflammatory conditions such as rheumatoid arthritis.
Importance of Timely Diagnosis
- Essential to prevent permanent loss of function.
- Facilitates appropriate surgical or non-surgical treatment to improve recovery outcomes.
Factors Influencing Return to Work
- Complexity of the injury and necessary rehabilitation length increase challenges.
- Pain management and functional limitations can hinder full recovery.
Emotional and Socioeconomic Challenges
- Psychological impact can affect motivation and adherence to rehabilitation.
- Financial stress from medical expenses and work absence complicates long-term recovery.
Conditions Not Commonly Leading to Spontaneous Tears
- Osteoarthritis does not typically result in spontaneous tendon tears.
Clinical Manifestation of Jersey Finger
- Characterized by inability to flex the distal phalanx of the affected finger.
Injury Involving Distal Phalanx Avulsion Fracture
- Jersey finger involves avulsion fracture of the base of the distal phalanx.
Common Cause of Mallet Finger
- Typically results from an object striking the fingertip, causing tendon rupture at the distal interphalangeal joint.
Deformity of Flexion at PIP and Hyperextension at DIP
- Recognized as a boutonniere deformity.
Characteristic of Boutonniere Deformity
- Presents with a prominent extension lag at the distal interphalangeal joint.
Conservative Management of Mallet Finger
- Commonly involves splinting of the finger in an extended position for several weeks.
Mallet Finger Deformity Result
- Results from acute rupture of the extensor tendon at the distal phalanx.
Shared Characteristic of Jersey Finger and Mallet Finger
- Both conditions involve tendon injuries leading to functional deficits in finger flexion and extension.
Tendon Disruption in Boutonniere Deformity
- Typically results from disruption of the central slip of the extensor tendon.
Specific Tendon Injury in Jersey Finger
- Primarily involves injury to the flexor digitorum profundus tendon.
