MLB Injury Expert Will Carroll on Early Spring Training Injury Surge

Early Spring Hamate Bone Injuries

• 💡 Hamate bone injuries are prevalent in early spring training, affecting players like Francisco Lindor, Corbin Carroll, and Jackson Holliday, potentially causing them to miss the start of the season.
• ⚾ These injuries often appear as clusters of bad luck, making them seem more widespread due to the involvement of high-profile, fantasy-relevant players.
• ⚠️ While often attributed to being hit by a pitch, many hamate fractures occur from the knob of the bat impacting the bone during a swing, especially for players who grip the bat with their hand off the knob.

Understanding Hamate Bone Mechanics

• 🦴 The hamate bone, located under the pinky, has a hook-like structure that receives poor blood flow, making healing difficult.
• 🛠️ Surgical intervention typically involves removing the hook or the entire bone, as the hook rarely reattaches, though whole bone removal is less favored due to wrist complexity.
• 📉 Post-surgery, players commonly experience a power drop for about six weeks due to hand immobilization and loss of strength in the hand and wrist, requiring time to regain full function.
• 🔍 Lindor's case is a stress reaction, not an acute fracture, which is being detected earlier thanks to improved scanning technology.

Diverse Blue Jays Injury Concerns

• 🍁 The Toronto Blue Jays face multiple early-season injuries, including Anthony Santander's shoulder surgery, Shane Bieber's delayed ramp-up, and Bowden Francis's UCL issue.
• 🩹 Santander's labrum repair is a complex shoulder injury that has seen improved surgical techniques and recovery times in recent years, though it still impacts his availability.
• 📈 UCL injuries are common early in the season (around 40% before May 1st) due to players ramping up too quickly after the offseason, though better workload management is reducing this.

UCL and Degenerative Disc Insights

• 🧠 While UCL injuries are often due to improper ramp-up, modern sports science is helping to create scientific "ramps" to keep player workload in a "green zone" and reduce early-season occurrences.
• 🛑 Chris Bryant's degenerative disc disease in his lower lumbar is a severe, potentially career-ending injury for a baseball player, as it impairs the twisting motion essential for hitting and throwing.
• ⚙️ Unlike a normal person who might recover quickly from back surgery, the specific forces and twisting motions required in baseball make it extremely difficult for players with disc fusions to return to elite performance.

Other Notable Player Injuries

• 🤕 Hassan Kim's torn finger tendon (not an ankle injury as initially misremembered) highlights the impact of grip strength on a player's ability.
• 🦴 Bone spurs (like Spencer Strider's elbow issue) are often a signal from the body that something else, potentially the UCL, is under stress, even if the spur itself is easily removed.
• 🦵 Joe Jimenez's left articular cartilage injury in his knee is complex, potentially leading to bone-on-bone issues and long-term solutions like knee replacement, impacting his ability to play for an extended period.
• 💪 Josh Hader's bicep inflammation is likely a shoulder issue, indicating an imbalance in forces or altered mechanics that his shoulder cannot handle, despite early season ramp-up.

The "Injury Territory" Show

• 🎙️ The new "Injury Territory" show aims to provide context and explanation for injuries, moving beyond just listing them.
• 🔬 It will feature experts from inside the game, including athletic trainers, doctors, and sports scientists, to discuss why injuries happen and their implications.
• 🔮 The show will explore how data and AI are influencing training rooms and injury prevention strategies in professional sports.
