Yankees’ closer Aroldis Chapman was placed on the 10 day DL last Sunday with what was reportedly diagnosed as a rotator cuff strain. He had evidently tried to work through discomfort in his last two outings, the combination of which caused his ERA to jump from 0.79 to 3.55. Read More ›
Jon Niese, the New York Mets 26-year-old leftie, is reportedly back in New York to see team doctors and get an MRI on the shoulder that caused him to leave the game early in the fourth inning yesterday. Niese noted that he’d felt great after missing a start and having 12 days of rest in late May and early June due to what was reported to be tendinitis. Though he apparently also expressed that he was not overly concerned about the shoulder despite the reappearance of symptoms, it seems logical for Mets fans and management to worry.
Though I’ve no information about the particular tendon previously involved for Niese, I assume it is one of his rotator cuff tendons. Like most non-traumatic sports ailments, tendinitis is an overuse injury. Tissues are simply subjected to more demand than they can tolerate. The result? Breakdown. Sometimes the cause entails weakness of specific muscles or strength imbalances. Insufficient muscular endurance to undertake a repetitive activity might be another issue. This is particularly true with overhead motions, such as those common in throwing and racquet sports, which involve complex dynamics. At the shoulder, variants in the shape of the acromion, a portion of bone overlying the joint (view image) can place additional stress on a tendon, making it more vulnerable. Another outcome of any of the above factors could be impingement on a tendon, which also plays into a cycle of inflammation.
Niese reportedly complained of weakness in the shoulder before being removed from the game. Though he’d rested for only 12 days before his prior start, the rest that alleviated his symptoms might have contributed to further weakening from disuse.
As I’ve written about in previous columns, rest and treatment of inflammation – with or without cortisone – may relieve pain, but don’t address the causes. That is why we see so much recurrence of injury amongst players who may feel well enough to return to the field but find they can’t stay out there. Healing is often incomplete and underlying factors have not been sufficiently addressed – nor can they be – in the limited time allotted. In fact, if the healing is incomplete, the boundaries of function cannot be pushed in rehab to fully simulate the demands of competition. Then of course there are the many athletes who play through the pain, whether silently and without complaint or because they are encouraged to do so.
Niese’s numbers this season may be evidence that something is holding him back. His command is not as sharp as it had been, resulting in more walks and fewer strikeouts. Now – even before the midpoint of the season – he is out for the second time due to the left shoulder. The diagnosis may not turn out to pinpoint significant pathology, but that doesn’t mean it should be taken lightly.

Giants fourth-year running back, Ahmad Bradshaw, underwent three surgeries last January â€“ one to remove spurs from his right ankle, and one on each foot to repair fractures of both his right and left fifth metatarsals with the insertion of a screw.Â Bradshawâ€™s first post-op running session was in April and until yesterday, when
he reportedly ran in both practices, his immediate football future was questionable. All accounts Iâ€™ve read since then have been enthusiastic.Â A piece in the NY Post stated that Bradshaw was running well and will likely return kickoffs and punts once the season begins.Â However, though I hate to be the spoiler, I can only remain guardedly optimistic.
Which of Bradshawâ€™s surgeries was the bigger deal?
Wear and friction at a joint can promote changes in bone, which
responds to stresses by growing more bone.Â The irregular shape of the joint surfaces that results is due to this extra bone, or spurring.Â The spurs then take up space in the joint and, when the joint moves through the range of motion required for function, impingement occurs.Â This is painful, as nerve endings and other structures are pinched.Â Add impact from running, especially with the cutting patterns involved in football, and the situation can become untenable.Â Removing the spurs arthroscopically, if that is all that Bradshawâ€™s ankle surgery entailed, is a fairly routine procedure, and he likely healed well.Â Is it always this simple? â€“ Absolutely not.Â Sometimes there is more that might have contributed to an athleteâ€™s condition.Â Perhaps there are additional diagnoses that may or may not have been addressed.Â Or, there could be underlying factors that predisposed an individual to the formation of spurs, such as structural mal-alignment, mechanical flaws in the manner in which an athlete runs, or even consistently running in one direction on a banked surface.Â Â Simply stepping up a training program too aggressively can create undue stress on the weight-bearing joints.Â These and other issues might persist once spurs are removed.Â If so, with return to competition, the long-term result would be that over time the spurs will reappear.Â I donâ€™t know the specifics of Ahmad Bradshawâ€™s circumstances and so I make no predictions.Â
Fifth Metatarsal Fracture Fixation
Surgical fixation of fractures of the fifth metatarsal (MT), the long bone of the midfoot that connects the little toe to the bone just in front of the heel, can be tricky.Â These fractures come in several varieties, based on their exact location and whether they are acute (from a recent trauma) or chronic (typically this is due to an unhealed stress fracture).Â The most common fracture of the fifth metatarsal is an avulsion fracture, where a small portion of the base of the bone is pulled away from the body of the bone. At the fifth MT, avulsion is most often due to the pull of the connective tissue at the base of the foot or tension from a particular muscle of the lower leg that attaches at the fifth MT.Â Â A â€œDancerâ€™s fractureâ€ of the fifth metatarsal typically occurs with twisting of the ankle, otherwise known as an inversion sprain (Oâ€™Malley, 1996).Â These MT fractures may be accompanied by fractures of the outer ankle.Â Though Iâ€™ve not seen detailed reports of his injuries, I would guess that Bradshawâ€™s fractures were most likely of the Jonesâ€™ variety rather than avulsions.Â Jonesâ€™ fractures occur in an area connecting the base of the fifth metatarsal with the shaft of the bone, and they often prove to be stubborn injuries.
Studies have demonstrated that only about two-thirds of acute fifth metatarsal fractures heal well with non-operative treatment (Wheelessâ€™ Textbook of Orthopaedics).Â Conservative care
initially entails wearing a non-weight-bearing cast for about 6-8 weeks followed by therapy.Â Surgery is the treatment of choice for those with delayed healing or incomplete healing of the bone, known as non-union.Â In these chronic cases, only a percentage of the fractures will mend without surgical intervention, and those that do require prolonged treatment during which time an individual cannot participate in sports.Â Likewise, when a fracture is displaced (where the two ends of the bone donâ€™t line up) or where an avulsion entails a large piece of bone being pulled away, surgery is warranted.Â An athlete, such as Ahmad Bradshaw, may opt for surgery rather than risk being out for an extended period only to find out that his fracture still hasnâ€™t healed.Â Post-operatively you can be sure that he was monitored carefully and only allowed to return to activity once full union (mending) of the bone was established.Â This is because a premature return to activity can result in failure of the fixation (Larson, 2002).Â Some athletes, even after surgery and a carefully executed rehabilitation plan, suffer from re-fracture.
So, the answer to my question is clearly that the fixation of Bradshawâ€™s metatarsals was the more sensitive of his surgeries.Â After working to control his post-operative inflammation and pain, regain his strength, range of motion, endurance, flexibility and balance, Mr. Bradshaw began to run again.Â Iâ€™ve read that he has been trying to adjust his running technique â€“ attempting to place less stress on the outer border of his feet â€“ to avoid re-injury.Â That may be a tough go.Â Weâ€™ll keep an eye on himâ€¦
If you experience the onset of pain at the side or outer edge of your foot, seek treatment.Â The pain may seem to have been unprovoked or might have increased gradually.Â Donâ€™t hesitate if you find that the pain is more pronounced with walking and is exacerbated by running or sports participation.Â A negative x-ray doesnâ€™t even mean that you are in the clear.Â Remain on alert because stress fractures often donâ€™t show up on initial x-rays and may only be evident once they begin to heal.
