The burden of proof is on the employee to prove all elements of a claim. George-Brewer v. Penn Mar Southwest, 980 S.W.2d 147 (Mo.App. W.D. 1998). The claimant bears the burden of proving that not only did an accident occur, but that it also resulted in an injury. Rana v. Landstar TLC, 246 S.W.3d 614, 626 (Mo.App. 2001); Silman v. William Montgomery \& Associates, 891 S.W.2d 173, 175 (Mo.App. E.D. 1995); McGrath v. Satellite Sprinkler Systems, 877 S.W.2d 704, 708 (Mo.App. E.D. 1994).
Critical opinion evidence on the severity of permanent injury was excluded pursuant to well-taken hearsay objections from Employer and the SIF. The opinions expressed by Dr. Solman, Dr. Volarich, Dr. Musich and Dr. Mirkin in their respective reports are excludable hearsay. Section 287.210 (7) RSMo (2005) provides protections for the parties against use of hearsay medical evidence. The section provides that if a physician's report is to be submitted into evidence, the party intending to submit that report must send formal Notice of that intended use at least sixty days prior to the hearing and must provide reasonable opportunities for crossexamination by deposition of the physician-author. Claimant did not comply with the statutory requirements and, as a result, the opinions of Dr. Solman, Dr. Volarich, Dr. Musich and Dr. Mirkin are not admitted. Specifically, Claimant is without admissible expert opinions on permanent partial disability (PPD) percentages (and need for future treatment).
On the other hand, the testimony of a claimant or other lay witness can constitute substantial evidence of the nature, cause, and extent of disability when the facts fall within the realm of lay understanding. Silman v. William Montgomery \& Associates, 891 S.W.2d 173, 175 (Mo.App. E.D. 1995); McGrath v. Satellite Sprinkler Systems, 877 S.W.2d 704, 708 (Mo.App. E.D. 1994). Medical causation, not within the common knowledge or experience, must be established by scientific or medical evidence showing the cause and effect relationship between the complained of condition and the asserted cause. McGrath, supra.
It has also been found that " $[t]$ he extent of an employee's disability, and thus employability, is not an issue of medical causation, nor does it exclusively require medical testimony." Schussler v. Treasurer/Custodian of Second Injury Fund, 328 S.W.3d 294 (Mo.App.
2010). The Commission "may consider all the evidence and the reasonable inferences drawn from that evidence." Id. at 296, quoting Carkeek v. Treasurer/Custodian of Second Injury Fund 352 S.W.3d 604, 610 (Mo.App. 2011).
Here, Employer accepted liability and tendered substantial benefits to Claimant, including surgery by their authorized physician, Dr. Miller. Claimant offered substantial evidence of his right shoulder injury, treatment and surgery by Dr. Miller. (Exhibit G.) Dr. Miller's treatment records establish surgery performed on April 21, 2008 with post-operative diagnoses of superior labrum anterior and posterior tear and a healed/intact previous labral repair. Dr. Miller's clinical notes of February 18, 2009 (ten months post-surgery) reflect no atrophy, considerable discomfort with internal rotation to T10-T11, good strength, a positive O'Brien's test, and superior shoulder pain with anterior translation of the humeral head. Dr. Miller recommended the 2009 MRI referenced below.
On February 3, 2010, Dr. Miller recorded a patient history of Claimant failing the "pulling the dummy drill" and that he had been asked to retire because of his shoulder. Clinical findings that date included no atrophy but a positive impingement sign, internal rotation of T12T10, good strength, a positive O'Brien's test, painful clicking with anterior translation, and a positive apprehension test. Dr. Miller notes Claimant continues to have mechanical symptoms. Dr. Miller's plan was a diagnostic arthroscopy and biceps tenodesis. None of Dr. Miller's postsurgical notes suggest a new injury that might break causation between these post-surgical findings/recommendations and the surgery itself.
Claimant also offered his radiological records in evidence. (Exhibit H.) Approximately ten months post-surgery, on February 27, 2009, Claimant underwent an MRI of his right shoulder for "increased pain, possible recurrent labral tear." Findings included: "post-operative changes involving cartilaginous labrum" and "mild supraspinatus tendonitis." Claimant, again, underwent an MRI almost a year and one-half later, on July 28, 2010, for shoulder pain with the findings: biceps tendinopathy or small split without complete tear and mild undersurface partial tear of the supraspinatus tendon distally slightly progressed since previous without complete tear or retraction. Each of these MRI studies demonstrates ongoing, post-operative, treatable symptoms on these dates according to the referring surgeons, Dr. Miller and Dr. Solman, respectively.
The authorized surgery together with these post-operative treatment records support a finding of significant disability of the right shoulder. The objective clinical notes of the authorized surgeon, taken in context of the post-surgical calendar, are corroborated by MRI study. Similarly, clinical notes of Dr. Solman, also post-surgical in time, are corroborated by another MRI study. The comprehensive result of these treatment events is proof of a course of chronic pain, positive clinical findings for shoulder examinations, and positive MRI findings of treated and untreated pathology. Full communication of these findings with Claimant is presumed. These notes, and the reasonable inferences that may be drawn, are sufficient to predicate a finding of permanent partial disability.
Section 287. 190.1 RSMo (2005) provides that an employer shall pay compensation for "... the proportionate loss of use of any of one or more of the members mentioned in the schedule of losses." The shoulder is the first member mentioned in the Schedule. Section
287.190.1(1). Further, the statute requires that permanent partial disability shall be demonstrated and certified by a physician. Section 287.190.6. These terms are not defined in Chapter 287. Schussler and Carkeek were decided since passage of these requirements in the 2005 amendments.
Here, Claimant proffered medical records documenting the severe injury, surgery and post-surgical problems he sustained as a result of the reported accident. It is all-important here to note that Employer accepted liability in this case and for which Claimant received authorized treatment, including surgery. His post-operative complaints, corroborated by MRI findings certified by qualified physicians, demonstrate severe right shoulder injury with the above described chronic symptoms and limitations. A reasonable inference of some permanent partial disability is made from this record of evidence. However, because Claimant did not offer competent evidence of PPD attribution (i.e. proportionate losses) for this 2008 injury and that from his 2005 right shoulder injury, accordingly, the amount of PPD benefits that may be awarded is limited. See Bock v. City of Columbia, 274 S.W.3d 555 (Mo.App. 2008).
