CJSM Blog Journal Club — is rESWT an effective therapy for chronic, distal biceps tendinopathy?

I’m pleased to welcome Jason Zaremski MD, one of our junior associate editors, who has contributed our first on-line journal club article.

Dr. Zaremski is a primary care sports medicine specialist who is board certified in Physical Medicine and Rehabilitation. He is an assistant professor at the University of Florida in the Department of Orthopaedics and Rehabilitation.

Dr. Zaremski is also a member of one of our affiliated societies, the American Medical Society for Sports Medicine, and was appointed last year as the AMSSM junior associate editor.  He’s been busy behind the scenes on many CJSM initiatives already; this is his first foray onto the blog, and we’ve been looking forward to his contribution.  Enjoy!

Title: Furia JP, et al. Radial Extracorporeal Shock Wave Therapy Is Effective and Safe in Chronic Distal Biceps Tendinopathy. Clin J Sport Med 2017;27:430–437.

Introduction:

This is the first online Journal Club Commentary for the Clinical Journal of Sports Medicine’s new initiative for its Online Journal Club. Furia and colleagues sought to determine the efficacy and safety of radial extracorporeal shock wave therapy (rESWT) for chronic distal biceps tendinopathy (cDBT). This is a retrospective case control study with level three evidence. The specific aim of the study is to determine whether rESWT is safe and effective for the management of cDBT.

Isometric Contractions for In-Season Treatment of Patellar Tendinopathy

Guest blogger Dr. Napolitano grinding it out on the water.

One of the great features of modern medical journals like CJSM is the ability to publish studies ahead of print – we call it “Published Online First.”

With the flexibility  allowed by the internet and emerging media, we are able to get studies that have gone through peer review and are in the queue for printing out to the reading public months before they otherwise would see the light of day.

We have one of our “Published Online First” studies burning things up on emerging media.  At CJSM we follow the Altmetrics on the studies in our pages, and this new one — Isometric Contractions Are More Analgesic Than Isotonic Contractions for Patellar Tendon Pain: An In-Season Randomized Clinical Trial — currently has a very hot rating of 107 (and climbing).

The treatment of such a common condition will be of inherent interest to those who practice sports medicine. Moreover, managing this nagging condition in mid-season can prove to be a Sisyphean task for the athlete and clinician.  This study has great promise to make a significant impact on your care of the athletes you see.

I asked the physician fellow working with me at NCH sports medicine, Jonathan Napolitano, MD, to do a guest post on this study authored by Rio et al.  Dr. Napolitano’s commentary, forthwith:

________________________________________________________

Basketball season is upon us and our clinics have begun to fill with athletes ailing from patellar tendinopathy, seeking pain relief and a quick return to the hardwood.  As a sports medicine fellow with a residency background in physical medicine and rehabilitation I have used this time to step back and review the therapeutic exercises we prescribe for tendinopathies.  I have always paired the concept of eccentric strengthening with tendon repair.  However, various other types of muscle contraction and strengthening exercises can (and perhaps should be) prescribed as well.

As an educational exercise I would like to take a moment to review the types of muscle contractions.  Isometric contraction occurs without any movement of the joint on which the muscle acts.  Isokinetic contraction occurs at a constant speed across a joint range of motion with variable resistance.  Finally, isotonic exercises are performed through normal joint range of motion with a consistent resistance at variable speed.  Isotonic contractions are further divided into concentric (muscle shortening) and eccentric (muscle lengthening).

Tendon pain is a factor that limits participation and performance in athletes.  Eccentric strengthening has shown good clinical outcomes in the long-term; however, this intervention can lead to increased pain in the short-term, and in 2005 Visnes et al showed eccentric strengthening to be of no benefit for in-season athletes.

Recent research by Dr. Rio et al [including senior author Dr. Jill Cook] compared rehabilitation programs for in-season athletes with patellar tendon pain.  Read more of this post

Tip-off: The NBA Season is Set to Begin!

Kobe_Bryant_61_NYK3

“Kobe Bryant 61 NYK3,” by C.J. Iuzer.

The NBA regular season begins in a week, but there has been a lot happening already on the sports medicine front in the league.

From Paul George’s tib/fib fracture  to Kevin Durant’s ‘Jones fracture’  to Anthony Davis’ ‘wrist sprain,’  the athletic trainers, sideline physicians, and orthopaedic surgeons have had a busy ‘off season.’

And then, there is the question of Kobe.  He has been in the press a lot!

The NY Times recently had an interesting chat with the Kobe and Arianna Huffington, a unique friendship to say the least.  It seems Kobe is indeed looking at his future, however many seasons he may have in front of him.  And before he has even taken a shot in the regular season, pundits aplenty have shared their skepticism about his ability to perform on the court:  seems like a lot of folks are betting Kobe will be an albatross around the neck of the Lakers.

As most readers would know, Kobe Bryant ruptured his Achilles tendon at the end of the 2013 season. We blogged about it at the time (I’m reblogging the original post below) and discussed the pros/cons of operative vs. non-operative treatment of such injuries.  The issues of managing Achilles tendon pathology find their way frequently into the pages of CJSM.  Two such articles I would especially commend to the readers as being particularly relevant to the question of Kobe’s ability to recover:   “Complications after surgery or non-operative treatment for acute Achilles tendon rupture,”  and “Does accelerated functional rehabilitation after surgery improve outcomes in patients with acute Achilles tendon ruptures?”

Kobe, of course, went through operative treatment and an accelerated rehab.  His 2014 season was cut short because of a knee injury.  For the brief time he played, it would seem his Achilles held up quite well.  I suspect his knee injury was of the sort we saw after the NBA lockout, where a prolonged layoff from the sport can lead to higher rates of injury; that is, I think his knee injury was more linked to a prolonged absence from high-level running and jumping related to his prolonged recovery from Achilles tendon surgery.  A similar process was involved in Derek Jeter’s case, where a quick return from one injury (ankle fracture) led to a season-ending issue in another body part (quad strain).

I wouldn’t bet against Kobe, no sir.  He is as tough as they come, and throughout his career he has been at the forefront of athletes employing cutting-edge concepts in training and recovery.   I don’t know about the Lakers as a unit.  But I think Kobe can make some headlines that are not related to injury this season.  Draining 61 points at Madison Square Garden one more time in his career?  I think the Black Mamba may just have it in him.

I woke up this morning to hear very sad news that occurred in the NBA last night:  Kobe Bryant has ruptured his Achilles tendon.

Kobe, who turns 35 this year, is one of the most recognized athletes in the world (maybe one of the few things that China and the USA can agree on). He had been leading his team to crucial victories as they were making a playoff run when he succumbed to this not uncommon injury in the middle aged athlete. 

As he is quoted saying, he made a move he had executed a ‘million times’ when he felt like someone had kicked him in the leg, and he subsequently crumpled to the ground.  This is the classic history one might obtain when caring for an athlete with such an injury.  If you watch the video, you’ll see Kobe perform a classic…

Nadal’s Knees

Rafael Nadal, invincible on clay, just might be beaten by this man in table tennis (Portuguese Table Tennis Coach Afonso Vilela)

What a great week it has been at the French Open in Paris.  As I write, I see that Serena Williams has just closed out Maria Sharapova in straight sets to regain the title she last held 11 years ago in 2002.  The men’s final is set for tomorrow, with the incomparable Rafael Nadal facing his Spanish countryman David Ferrer after outlasting Novak Djokovic in an epic five-set semi-final match.

Like many of this blog’s readers, I have been amazed and entertained by men’s tennis over the last decade.  It truly is a golden era for the sport, with Federer and Nadal and Djokovic and Murray each seeming to outdo the other in feats of tennis heroics.  Just yesterday Nadal made an amazing between the legs shot in the fifth set, but is that perhaps outdone by the amazing forehand Djoko ripped off Federer to save match point in the 2011 U.S. Open (going on then to win the semi-final)?
