Ream and run for arthritis in a 41 year old with a B2 glenoid - remodeling at one year

A 41 year old man from New York presented to us with severe pain and loss of function of the left shoulder years after a prior surgical procedure for anterior instability. He could perform only 5 of the 12 functions of the Simple Shoulder Test. His preoperative films show capsulorrhaphy arthropathy with severe decentering on the the axillary 'truth' view.

Because of his active lifestyle, he elected a ream and run procedure. At that time an anteriorly eccentric humeral head and a rotator interval plication were added to re-center his humeral prosthesis on the glenoid. No cement, polyethylene or CT scans were used.

At one year after surgery, his humeral head was well centered on the remodeled glenoid. His impaction grafted thin smooth stem is well fixed.


His SST score had improved to 8/12.

Comment: This highly motivated man has regained excellent passive motion and is continuing to work on his strength. It is a work in progress.

Ream and run for arthritis in a 37 year old - 5 month progress report

A very active 37 year old male presented to us with a long standing history of right shoulder pain. He had history of a right shoulder dislocation at the age of 16 for which he underwent an arthroscopic bankart repair. He did well until approximately 2003, when he was involved in a motor cycle accident in which he sustained a shoulder fracture. He subsequently underwent a debridement and did well up until 2011 when he had a bicycle accident and sustained a second shoulder fracture (unsure of anatomic location). He then developed progressive stiffness and pain that did not respond to steroid injections. At the office visit he could perform only 3/12 of the Simple Shoulder Test functions. His radiographs are shown below


Because of his active lifestyle, he elected to have a ream and run procedure.

He recently sent this email from his home in South Africa:

"I wanted to touch base with you since now I am five months out of having the Ream and Run. Its been a bit up and down, as I'm sure you are aware of, but overall I know in the long run my shoulder is going to be much better off than it was prior to the procedure. I wanted to ask you about certain exercises to focus on and avoid. I've been sticking to the rowing, lat pulldowns, light yoga, and strengthen my back. The physiotherapist I am working here has added some external rotation exercises and I am finding them very problematic. I remember reading to avoid them for at least three months after surgery, which I did, but at five months one set of external rotation exercises will cause pain and stiffness in the front part of the shoulder for several days. I wanted to see if that was normal and what your thoughts were on the type of rehab exercises I should focus on?

On a side note, South Africa is a gorgeous country. After living in big Asian cities the last seven years it's nice to get back to a place, much like the Northwest, that I can enjoy an outdoor lifestyle. I'm not back to cycling yet, but once back on the bike I know I will enjoy it even more here. Appreciate your time and feedback."

He also sent these videos of his shoulder motion, which he generously gave us permission to show here






Comment: This five month progress report points out that the recovery of motion and function after a ream and run requires dedication and time. It also points to the importance of avoiding external rotator stretching until it can be performed comfortably

Cuff tear arthropathy: is a reverse necessary? The CTA arthoplasty

What Factors are Associated With Clinically Important Improvement After Shoulder Hemiarthroplasty for Cuff Tear Arthropathy?

These authors sought to determine the factors associated with achieving the minimum clinically important improvement in the Simple Shoulder Test (SST) in 42 patients (24 males/18 females) at a mean of 48 months (range, 24–132 months) after hemiarthroplasty for cuff tear arthropathy performed between 1991 and 2007.

The authors' indication for hemiarthroplasty was superior translation on plain radiographs of the humeral head with respect to the glenoid, loss of articular surface of the humeral head, bone loss of the superior glenoid, and erosion of the greater tuberosity and undersurface of the acromion. They excluded shoulders with instability of the shoulder with attempted forward elevation (anterosuperior escape), active infection, and inflammatory arthritis.

21 shoulders received a conventional humeral head replacement and 21 received a cuff tear arthropathy arthroplasty prosthesis. At surgery, soft tissue balancing
was thought to be ideal when the following criteria were achieved: (1) posterior drawer testing with 40% to 60% translation of the center of the prosthetic head relative to the center of the glenoid, (2) 60 internal rotation was present with the arm positioned in 90 abduction, (3) the hand on the involved side could be placed on the superior aspect of the contralateral shoulder without protraction of the scapula, and (4) there was 45 external rotation with the subscapularis approximated to the proximal humeral osteotomy site. Assisted motion was started immediately after surgery with progressive activities as comfort allowed.

At latest followup, 33 of 42 patients (79%) achieved a clinically important percentage of maximum possible improvement (%MPI), defined as an improvement of 30% of the total possible improvement on the 12-point SST scale. They reported no complications and no revision procedures.

Intraoperative findings of a rotator cuff tear limited to the supraspinatus and infraspinatus and limited preoperative external rotation were associated with achieving the defined minimum functional improvement (30% of MPI) on multivariate analysis. Preoperative active elevation and use of a CTA-specific implant were not significantly associated with achievement of 30% of MPI.

The results of the univariate analysis are shown here



and the results of their multivariate analysis are shown here



Comment: As appears to be the case in the practice of these authors, many of our patients with classical cuff tear arthropathy want to lead active lives. They wish to avoid a reverse total shoulder because of concerns about activity limitations, dislocation, screw breakage or humeral shaft fracture should they fall. If these individuals have active elevation > 90 degrees and have no evidence of anterior superior instability, we discuss the option of a CTA prosthesis.

Here's the example of a lady in her mid sixties with a failed cuff repair. Two years after that surgery she presented to us with a weak and painful shoulder. She was taking prednisone, methotrexate and Humira for her rheumatoid arthritis. She had active elevation to 110 and passive elevation to 160 degrees. Her x-rays at this time are shown below.



She elected a CTA arthroplasty. At surgery she had an irreparable cuff defect involving her supraspinatus and infraspinatus.

She dropped by to see us nine years after surgery. Her films at that time are shown below.

Her shoulder was painless. Her active elevation is shown below.




As another example we recently we saw an active physician-rancher who had had bilateral CTA prostheses performed after failed cuff repairs. Because he recognized that his ranching was demanding on his shoulders and carried the risk of falls, he preferred the CTA over the reverse total shoulder.

Before his left shoulder surgery his films were as shown below and he reported the ability to perform only 5 of the 12 Simple Shoulder Test functions. He was able to elevate his arm to over 90 degrees and had no anterosuperior instability.



At the time of surgery he had no supraspinatus, no infraspinatus and a detached subscapularis.
We were able to reattach his subscapularis.

At four years after surgery, he could perform 8 of the 12 SST functions and had the radiographs shown below. Note the impaction grafted humeral stem and the articulation of the prosthesis with the undersurface of the coracoacromial arch.

 


Two years ago he presented with a similar situation in his right shoulder. His SST score was 3/12. He had active elevation of 100 degrees without anterosuperior escape. His preoperative x-rays shown below.

Two years after his right shoulder arthroplasty he could perform 8/12 SST functions and was back at work on his ranch. His 2 year films are shown below.

 


Here's a video of his function at his last clinic visit.





Here is a video of an active women two years after her CTA arthroplasty for cuff tear arthropathy.



Here are the x-rays and the shoulder function of a man one year out from his CTA arthroplasty





Comment:  From our standpoint, the CTA arthroplasty is a most attractive option for consideration by active individuals with cuff tear arthropathy and the ability to actively elevate the arm above 90 degrees without manifesting anterosuperior instability.

It has a very low complication and revision rate, avoids issues of modular components and activity restrictions.

Inserting the prosthesis with impaction grafting makes for an easy conversion to a reverse should that be necessary, fortunately this is rarely the case. The cuff tear arthropathy prosthesis is considered for individuals with active elevation of 90 or more degrees without anterosuperior escape – especially those who desire higher levels of physical activity or those who are at increased risk of falls. It is important to realize that this prosthesis has an extended lateral joint surface for articulation with the undersurface of the coracoacromial arch, thus it is distinct from the usual hemiarthroplasty prosthesis. The implant system should allow selection of the appropriate diameter of curvature and should enable fixation by impaction grafting.

 

The surgical keys to a successful CTA arthroplasty are (1) optimizing stability and (2) matching the prosthetic diameter of curvature to that of the resected humeral head. The patient positioning, anesthetic, prophylactic antibiotics, skin preparation, and skin incision are identical to that for an anatomic arthroplasty. 

 

In exposing the humeral head, we retain as much as possible of the clavipectoral fascia attached to the coracoacromial ligament (the “CA+”) as an additional barrier to anterosuperior instability. 



The subscapularis is carefully incised from the lesser tuberosity taking care to keep the subjacent capsule attached to its deep side. The humerus is exposed by gentle external rotation allowing for debridement of cuff tendon remnants and osteophytes as well as sectioning of the long head tendon of the biceps if it remains intact. The humeral head height and diameter of curvature are measured, ideally before the head is resected.


The medullary canal is entered and progressively larger reamers inserted as sizers until the diaphyseal endosteal cortex is encountered at a depth corresponding to the length of the prosthetic stem (‘love at first bite’); this reamer defines the orthopaedic axis. The humeral head is resected at an angle of 45 degrees with the orthopaedic axis; the proximal humerus is prepared as for a standard humeral arthroplasty. The lateral tuberosity is resected. The humeral head diameter of curvature is chosen to match that of the resected head. Trial reduction is carried out. The height of the prosthesis is selected so that the deltoid is under mild-moderate tension when the arm is adducted. Impaction grafting is carried out using bone from the resected humeral head. If the biceps tendon is available, an in-and-out biceps tenodesis is performed. Drill holes are placed for reattachment of the subscapularis. The is prosthesis assembled and inserted and the subscapularis is securely repaired.

We first described our approach over two decades ago in a publication, Prosthetic replacement of the shoulder for the treatment of defects in the rotator cuff and the surface of the glenohumeral joint, which reported on twenty-one shoulders in nineteen patients, fifty-four to eighty-four years old, who had disabling pain attributable to a massive tear of the rotator cuff, accompanied by loss of the surface of the glenohumeral joint. These patients were not candidates for total shoulder replacement because of the massive deficiency in the cuff and the fixed upward displacement of the humeral head. At that time reverse total shoulder was not an option. A prerequisite for hemiarthroplasty was a functionally intact coracoacromial arch to provide superior secondary stability for the prosthesis. One important aspect of the operative technique was the selection of a sufficiently small prosthesis so that excessive tightness of the posterior aspect of the capsule could be avoided. Eighteen shoulders in sixteen patients were available for follow-up, which ranged from twenty-five to 122 months. Pain decreased from marked or disabling in fourteen shoulders preoperatively to none or slight in ten and to pain only after unusual activity in four. Active forward elevation improved from an average of 66 degrees preoperatively to an average of 109 degrees postoperatively. One patient, who had had an excellent result, fell and sustained an acromial fracture, so the functional result changed to poor. Three patients had persistent, substantial pain in the shoulder that led to a revision. Neither infection nor prosthetic loosening nor instability developed in any shoulder.

Ream and Run videos (re runs)

Some friends have surfaced some prior videos of the recovery after the ream and run and suggested we repost them here.

Here are a couple of recovery videos from 14 (see this link) and 16 weeks (see this link)

A six month (see this link) and nine month (see this link) followup

and here's a return to wood chopping (see this link).

Once again, the motivation of these individuals is apparent!

Ream and run, returning to have the second side done

After a successful ream and run on one shoulder, patients are returning to have the procedure on the opposite shoulder. Here is an overview of three such patients from last week.

#1 51 year old man with mild dysplasia and a preoperative SST score of 3 out of 12 and these x-rays

Three years after surgery his SST score had improved from 3/12 to 12/12. His three year x-rays are shown below.
                                     

#2 44 year old man with chondrolysis following the intraarticular infusion of local anesthetics after a labral repair; preoperative SST score of 2 out of 12 and these x-rays


Two years after surgery his SST score had improved from 2/12 to 9/12. His two year x-rays are shown below.
                                 

#3 61 year old man with osteoarthritis and a preoperative SST score of 6 out of 12 and these x-rays

One year after surgery his SST score had improved from 6/12 to 11/12. His one year x-rays are shown below.

                                      

Comment: It is indeed reassuring to see that motivated patients are sufficiently pleased with the result of their recovery after a ream and run procedure to pursue having it done on the opposite arthritic shoulder.

Note that none of the following are used in the care of our ream and run patients: a plastic glenoid component, preoperative CT scans, patient-specific instrumentation, preoperative MRIs, platform stems, short stems, stemless components, bone ingrowth components, cement, biceps tenotomy, biceps tenodesis, brachial plexus blocks, or lesser tuberosity osteotomy.

Superman pushups after bilateral ream and run procedures

One of our star patients recently posted this on his Facebook:

"For those of you who have recently had your R&R procedure or will experience it soon:
Your goal should be to eventually enjoy 100% recovery. The results are mostly up to you. Do the work. Do the stretches. Slowly ramp up the strength exercises. Do them 2-5 times a day. Every day.
I’m 7 years post procedure with my left and 5 with my right. I still use my rope and pulley.
The video was taken today. You probably don’t have a need to perform ‘Superman push-ups’, but you want the best result. Do the work."

The narcotic epidemic - how can surgeons and patients address it?

Leading the Way to Solutions to the Opioid Epidemic

These authors point out that in the past 2 decades, overdoses and deaths from prescription opioids have reached epidemic proportions in the United States. The widespread use of opioids complicates management of the orthopaedic surgery patient in the acute and chronic settings. Orthopaedic surgeons are some of the top prescribers of opioids in the complex setting of chronic use, abuse, and diversion. In addition to reviewing the literature regarding the basic science of pharmacologic options for pain management (e.g., opioids and nonsteroidal anti-inflammatory drugs), they authors present some solutions to address the current opioid crisis.

One of the most disturbing parts of this article is 'how we got here'. Below is a summary:
"While opioids have long been used to treat acute pain following traumatic injury and during the postoperative period, the expansion of the use of these opioid analgesics to noncancer pain outside of the acute or immediate postoperative setting started to become more commonplace in the 1990s based on the conclusions published by Portenoy and Foley .. claiming the safety and efficacy of opioids for chronic noncancer pain, despite small patient numbers culled from 2 different studies with moderate results and several complications. At that time, extended-release oxycodone (OxyContin) entered the marketplace with claims of increased effi cacy and safety. Subsequently, the manufacturer admitted to false marketing on the safety of OxyContin , and studies have not demonstrated the increased efficacy of extended release over immediate release. Pain advocacy groups and pain specialists, many of whom have substantial financial relationships with pharmaceutical companies, successfully lobbied... to put pain at the center of all patient assessments. Physicians faced increased pressure to prescribe more opioids . This opened the door for aggressive marketing by pharmaceutical companies to expand the use of opioids to noncancer pain; the marketing included educational materials supplied by The Joint Commission, which were sponsored by Purdue Pharma....most studies were sponsored by the pharmaceutical manufacturers... a "1% risk of addiction” is commonly cited...subsequent studies have demonstrated that the risk of addiction to prescription opioids is 3% to 45% when they are used on a long-term basis. Furthermore, if patients take prescription opioids beyond 12 weeks, 50% will still be taking them at 5 years"

Here are some 'flags' they identified for possible opioid abuse.

 Here are some risk factors they associated with opioid abuse.
 Here are some non-opioid approaches to pain management around the time of surgery

And here are some suggestions for surgeon-patient discussions of pain management.





Comment: This is a most informative article. It points to ways that both surgeons and patients can be part of the solution, not part of the problem.

A thoughtful editorial on this issue has been written by Seth Leopold (see this link). He points out that "the United States represents only 4.6% of the world’s population, but Americans consume 80% of the global opioid supply and 99% of the hydrocodone. In 2015, more than 52,000 people in the United States died from drug overdoses, and some 15,000 of those overdoses involved a prescribed opioid. The CDC reports that prescription-opioid abuse, dependence, and overdose costs the US economy an estimated USD 78.5 billion each year."

Today I was consulted by a 32 year old patient who had chronic pain after orthopedic surgery performed 17 years ago. The patient has had a total of 7 surgeries and is now on Oxycontin and Oxycodone in large doses.

Our practice is to (1) inform patients before surgery that recovery from surgery is likely to be painful, but that is expected and not a sign than things are wrong, (2) let them know that our primary medications for pain control are Tylenol and anti-inflammatory medications - narcotics will be limited to the first two weeks after surgery, (3) avoid using nerve blocks to temporarily 'mask' pain and (4) be very cautious about performing elective surgery on patients taking long-acting and / or high dose narcotics, because pain is likely to persist even after a 'perfect' procedure.
