The Most Common Upper Extremity Injury
Finger and hand injuries are the third most common injury site in volleyball, accounting for approximately 13.4% of all acute injuries – trailing only ankles and knees. A large-scale study of youth volleyball players found that 43% of all upper extremity injuries involved the fingers, with sprains and strains making up 42.6% of those cases. The sport-specific movement most commonly associated with finger injury is blocking, followed by defensive digging and setting.
Types of Finger Injuries in Volleyball
- Sprains and strains (39%): The ligaments connecting finger joints are stretched or partially torn
- Fractures (25%): One or more bones in the finger are broken
- Dislocations: The finger bones are forced out of their normal alignment
- Tendon avulsions: The tendon tears away from the bone, sometimes pulling a piece of bone with it
- Contusions (16%): Bruising from direct impact with the ball
The thumb metacarpophalangeal (MCP) joint is the most frequently injured area, as it bears the brunt of impact during blocking.
Why Finger Injuries Are Common in Volleyball
Ball Speed and Impact Force
A volleyball spike can reach speeds of 60-80 miles per hour at the high school level and over 70 miles per hour at elite levels. When a ball traveling at this speed makes contact with an outstretched finger, the force can easily bend the finger beyond its normal range, causing ligament damage or fracture.
Blocking Mechanics
Blockers extend their hands above the net to deflect the ball. The hands are exposed and vulnerable, especially when the block is not perfectly formed. If the blocker’s fingers are slightly apart when the ball hits, individual fingers absorb the full force of the spike. Studies show that most finger injuries during blocking happen when the hand is incorrectly positioned.
Setting Repetition
Setters absorb thousands of ball contacts per week. Each set puts pressure on the fingertips and finger joints. Over time, this can lead to overuse injuries of the finger tendons and ligaments.
Which Positions Are Most at Risk?
Middle Blockers
Middle blockers face the highest finger injury risk. Their position at the net requires them to block the opponent’s fastest and most powerful hitters. The middle blocker is involved in nearly every play at the net, providing more opportunities for finger trauma. Research confirms that most finger injuries occur during blocking.
Outside Blockers and Opposite Hitters
These players also block regularly, putting them at significant risk. Additionally, when hitting, if their hand contacts the net or an opponent’s hand, they can sustain finger injuries.
Setters
Setters face a different type of finger injury risk – overuse rather than acute trauma. The repetitive impact of setting can cause cumulative damage to the finger joints and tendons. Setters also risk acute injuries when attempting to block or when digging a hard-driven ball.
Liberos and Defensive Specialists
Liberos use their forearms for passing and rarely suffer acute finger injuries. However, when attempting a “pancake” save (sliding a hand under the ball just before it hits the floor), the hand and fingers are vulnerable to floor contact injuries.
Evidence-Based Prevention Strategies
Proper Hand Positioning
For blockers, the key prevention strategy is proper hand position. Hands should be:
- Shoulder-width apart
- Palms facing the net (not the ceiling)
- Fingers spread but firm
- Wrists slightly flexed
- Arms fully extended overhead
When the hands are positioned correctly, the ball contacts the palms rather than the fingers.
Taping and Bracing
Finger taping is one of the most effective prevention tools. Research supports using:
- Buddy taping: Taping the injured finger to the neighboring finger for support. This is the “gold standard” for returning to play after a jammed finger.
- Rigid tape: For blockers who need maximum stability to prevent finger joints from folding during impact.
- Elastic tape: For setters who need full range of motion with light compression.
Players should check and potentially retape between sets, as sweat reduces adhesive effectiveness.
Hand Strengthening
Stronger fingers and hands are more resistant to injury. Grip strength exercises should be part of every volleyball player’s training.
Proper Technique
Coaches should emphasize proper hand position during blocking drills. Players should practice keeping their fingers firm and hands properly positioned even when fatigued.
Strengthening Exercises for Prevention
Exercise 1: Grip Strengthening
Use a tennis ball or stress ball. Squeeze and hold for 5 seconds, then release. Perform 3 sets of 15 reps on each hand. This strengthens the intrinsic hand muscles.
Exercise 2: Finger Extensor Strengthening
Place a rubber band around your fingers (at the middle joint). Open your fingers against the resistance of the band. This strengthens the extensor muscles that balance the flexors. Perform 3 sets of 15 reps.
Exercise 3: Finger Adduction/Abduction
Place your hand flat on a table. Spread your fingers apart as wide as possible, then bring them back together. Repeat 20 times. This improves finger control and coordination.
Exercise 4: Wrist Flexor and Extensor Strengthening
Rest your forearm on a table with your hand hanging over the edge. Hold a light weight:
- Palm up: curl your wrist up (flexion)
- Palm down: curl your wrist up (extension)
Perform 3 sets of 12 reps each direction.
Exercise 5: Rice Bucket Training
Fill a bucket with rice. Plunge your hand in and perform various movements – squeezing, spreading, rotating. The resistance of the rice provides a comprehensive hand and finger workout.
Conclusion
Finger and hand injuries are the third most common injury in volleyball, with middle blockers at highest risk. Most occur during blocking when the hand is improperly positioned. Prevention focuses on proper hand positioning, strategic taping, and hand strengthening exercises. If you jam a finger, use buddy taping to return to play safely – but have it evaluated by a medical professional if you cannot fully bend or straighten it.
