lessons learned from the playing field

Learning about medicine from the playing field.

Randall Cobb of the green Bay Packers, leaps to catch a pass, lands awkwardly and sustains a pulmonary contusion, or bruised lung. After coughing up some blood, never a good thing but many times not disastrous, he is observed in hospital and is discharged home where his lung will slowly heal, just like any other bruise. The injury is a reminder that with chest trauma, and many people fall and hit their ribs, the x-rays done are to evaluate the lungs and not the bones. Doctors are more interested in whether there is a collapsed lung (pneumothorax) or lung contusion, while the patient is more interested in whether there is a broken rib. Regardless of whether the ribs are bruised or broken, the treatment is the same: pain control so that the patient can take a deep breath and expand the lung to prevent pneumonia, the most important complication of a minor chest injury.

Steeler receiver, Antonio Brown, suffered a concussion in the game against the Cincinnati Bengals and within 24 hours there were reports that he would be recovered within the week to play in the team’s next game. He did not. After his concussion, Green Bay Packer, Sam Shields took a month to recover before play9ing again. It is a reminder that there is no way to predict the brain’s path to recovery from concussion and there is no definitive test to determine that a brain has fully recovered and is able to withstand another blow. No matter the NFL protocols, concussion remains a diagnosis made at the bedside and return to play has no standard playbook to follow.

finger bony anatomy

Carson Palmer of the Arizona Cardinals had a new splint on the right index finger of his throwing hand to protect the PIP joint that had been dislocated. Fingers have three joints (the thumb has two), the metacarpophalangeal (MCP) that connects the finger to the hand, and the proximal interphalangeal (PIP) and the distal interphalangeal (DIP) joint. The PIP joint is commonly dislocated and can heal relatively easily but because of the complex anatomy of the hand, the bones can damage the tissues and tendons that surround the joint when they dislocate. Complications include a volar fracture of the thin plate of bone on the palmar surface of the joint can be broken, leading to joint instability and a boutonniere deformity where the tendons slide to the side of the joint and prevent the finger from completely straightening. It’s a reminder that hands are complicated and minor injuries may lead to major long term complications.

Joakim Noah of the Chicago Bulls dislocated his shoulder and will undergo surgery to stabilize the joint. In most people, surgery is not the first step in rehabilitation. They are allowed to undergo physical therapy to strengthen the shoulder and return range of motion before considering an operation. But in athletes or those who may not be able or willing to limit their activities, surgery is often the first and potentially curative step. Studies of young athletes and military recruits, that surgery after the first shoulder dislocation can prevent future dislocation 95% of the time. Without an operation only 5% will have stable shoulders. The reason has to do with the inherent instability of the shoulder. It is designed to have a wide arc of range of motion in all directions and for that reason, the surface area of bone in the joint is very small. The stability has to do with the soft tissues that hold the shoulder together from the capsule and the labrum to the ligaments and surrounding muscles.  When the shoulder dislocates, all these structures are damaged and stretched. Surgery, either arthroscopic or through an incision, is meant to tighten all the structures that have been torn apart. Rehabilitation takes months to return range of motion and power; Mother Nature does not like to be rushed when she heals soft tissues.
