RECORD OF PROCEEDINGS PHYSICAL DISABILITY BOARD OF REVIEW NAME: XXXXXXXXXXXXXXXXX BRANCH OF SERVICE: ARMY CASE: PD1200971 SEPARATION DATE: 20030606 BOARD DATE: 20130306 SUMMARY OF CASE: Data extracted from the available evidence of record reflects that this covered individual (CI) was an active duty SFC/E-7 (63E40/M1A2 Tank Maintenance Supervisor) medically separated for a lumbar spine condition. He developed radiating low back pain (LBP) in 1998 which was subsequently diagnosed as degenerative disc disease (DDD) requiring surgical intervention. Surgical response was initially satisfactory, but symptoms escalated in 2001 and were associated with persistent bilateral foot numbness. The condition could not adequately rehabilitated to meet the physical requirements of his Military Occupational Specialty (MOS) or satisfy physical fitness standards. He was issued a permanent P3/L3 profile and referred for a Medical Evaluation Board (MEB). Two diagnoses, “severe lumbago” and “bilateral foot sensory loss,” were forwarded to the Physical Evaluation Board (PEB) as medically unacceptable in accordance IAW AR 40-501. No other conditions were submitted by the MEB. The PEB adjudicated the separate MEB diagnoses as a single unfitting condition, characterized as “chronic back pain, status post L5-S1 fusion with lower extremity neuropathy manifested by numbness and absent right Achilles reflex;” rated 20% with likely application of the US Army Physical Disability Agency (USAPDA) pain policy or AR 635-40. The CI applied for Continuance on Active Duty as an exception to policy under the provisions of Chapter 6, AR 635-40, Physical Evaluation for Retention, Retirement, or Separation. The U.S. Army Physical Disability Agency (USAPDA) did not favorably consider the request and the CI was medically separated with a 20% disability rating. CI CONTENTION: The application states simply, “L5 laminectomy with bilateral inferior facetectomy and L5-S 1 fusion using Ray threaded fusion cages and autologous iliac crest graft: 20 January 1998.” The CI does not elaborate further or specify a request for Board consideration of any additional conditions. SCOPE OF REVIEW: The Board’s scope of review is defined in DoDI 6040.44, Enclosure 3, paragraph 5.e. (2). It is limited to those conditions determined by the PEB to be unfitting for continued military service and those conditions identified but not determined to be unfitting by the PEB when specifically requested by the CI. The rating for the unfitting lumbar spine condition (with associated radiculopathies) is addressed below; and, no additional conditions are within the DoDI 6040.44 defined purview of the Board. Any conditions or contention not requested in this application, or otherwise outside the Board’s defined scope of review, remain eligible for future consideration by the Army Board for Correction of Military Records.

The medical records show intermittent conservative treatment (non- steroidal anti-inflammatory medications, physical therapy, and profiling) for LBP from 1992 up to 1997 due to training injuries. In 1997 his LBP recurred with radiation and paresthesias into both lower extremities and associated night pain. Orthopedics evaluated him and reviewed X- rays which revealed grade I L5-S1 spondylolisthesis with bilateral L5 spondylolysis and referred him to an orthopedic spine surgeon. The spine surgeon initially recommended conservative treatment. Five months later he developed weakness of the right foot with decreased sensation, consistent with L5 dermatome, and diminished right ankle reflex. A magnetic resonance imaging (MRI) exam confirmed L5-S1 DDD and spondylolysis with pars defect and thus the CI underwent L5-S1 instrumented fusion surgery in January 1998 for refractory pain and progressive symptoms. The post surgical and rehabilitation period were without complications. The CI noted some foot numbness postoperatively; however he was performing his duties with a P2 profile for status post (s/p) spine fusion that limited only sit-ups. The record was silent for treatment from August 1999 until February 2001 when he sought care for recurrence of LBP and he occasionally needed a narcotic based pain medication for acute flares. A repeat MRI revealed; L4-L5 herniated nucleus pulposus (HNP, herniated disc), DDD, and spondylolysis with no significant narrowing, and s/p bilateral laminectomy procedure at the L5- S1 with no spinal stenosis. A new permanent profile was issued in October 2002 for s/p spinal fusion with hardware implantation with more restrictive limitations to include no tactic vehicles, ruck march or sit-ups, no crawling and no stooping. The profile allowed a bending time limit of 30 minutes, alternate event for physical fitness testing and use of cane and back brace as needed. The commander’s statement corroborated the medical condition and additionally documented the CI was assigned to administrative duties. The commander further opined the CI could continue to perform in his MOS if assigned in units; that did not require operations on military vehicles and urged his retention on active duty in a duty position appropriate to his profile. The narrative summary (NARSUM), 8 months prior to separation, demonstrated; normal range- of-motion (ROM), motor strength 5 of 5 bilaterally in the upper & lower extremities; subjective decreased to pinprick in the right L5 and left S1 dermatomes, absent right ankle jerk and otherwise normal neuromuscular findings, antalgic but not ataxic station and gait, negative straight leg raise (SLR) bilaterally (provocative testing for disc disease), a well healed scar, and no Waddell's signs. X-rays revealed s/p L5-S1 fusion with no instability, hardware failure, or impingement. The examiner opined the LBP was moderate and constant. At the VA Compensation and Pension (C&P) exam performed a month prior to separation, the CI reported 5 of 10 constant dull LBP that increased to an 8-9 of 10 sharp pain two times per week with normal daily activity. The pain subsided in one day after treatment with nonsteroidal anti- inflammatory and narcotic based pain medication. Associated symptoms included radicular pain to the bilateral legs down to the feet two times per month and constant numbness of the bilateral feet. His reported daily activity limitations included could not; lift greater than 20 pounds, stand greater than 15-20 minutes at a time, run or perform jarring activities. The C&P exam demonstrated normal painful ROM, normal posture and gait, bilateral numbness, absent right Achilles' reflex and normal motor strength, bilaterally. X-rays revealed moderate osteophytosis, and moderate disk protrusion with degenerative spondylosis. The Board directs attention to its rating recommendation based on the above evidence. The PEB and VA based their rating recommendations IAW 2002 VASRD coding and rating standards for the spine, which were in effect at the time of separation, were modified on 23 September 2002 to add incapacitating episodes (5293, Intervertebral disc syndrome), and then changed to the current §4.71a rating standards on 26 September 2003. The 2002 standards for rating based on ROM impairment were subject to the rater’s opinion regarding degree of severity, whereas the current standards specify rating thresholds in degrees of ROM impairment. Both the PEB and the VA rated the CI’s lumbar spine condition at 20% coded 5295. The Board notes the NARSUM is absent for muscle spasm or loss of lateral spine motion which allows for a 20% 5295 rating, however the Board's recommendation may not produce a lower rating than that of the PEB. The Board considered a rating under the 5292 code for limitation of spine motion. Neither the MEB nor the VA normal ROM’s documented would justify a “moderate” 20% rating under that code. There is no evidence of documentation of incapacitating episodes to meet criteria under the 5293 code which would provide for a higher rating. The Board also considered whether an additional rating for sciatic radiculopathy, as conferred by the VA, was appropriate in this case. Board precedent is that a functional impairment tied to fitness is required to support a recommendation for addition of a peripheral nerve rating at separation. The sensory component in this case has no functional implications. Furthermore, after the spinal fusion and prior to separation there is no physical finding of motor weakness to consider for significant functional impairment. All members agreed, therefore, that a recommendation for additional rating based on peripheral nerve impairment is not supported. After due deliberation, considering all of the evidence and mindful of VASRD §4.3 (Resolution of reasonable doubt), the Board concluded that there was insufficient cause to recommend a change in the PEB adjudication for the low back pain condition. BOARD FINDINGS: IAW DoDI 6040.44, provisions of DoD or Military Department regulations or guidelines relied upon by the PEB will not be considered by the Board to the extent they were inconsistent with the VASRD in effect at the time of the adjudication. The Board did not surmise from the record or PEB ruling in this case that any prerogatives outside the VASRD were exercised. As discussed above, likely PEB reliance on the USAPDA pain policy or AR 635- 40 for rating lumbar spine condition was operant in this case and the condition was adjudicated independently of that policy or instruction by the Board. In the matter of the lumbar spine condition and IAW VASRD §4.71a, the Board unanimously recommends no change in the PEB adjudication. There were no other conditions within the Board’s scope of review for consideration. RECOMMENDATION: The Board, therefore, recommends that there be no recharacterization of the CI’s disability and separation determination, as follows: UNFITTING CONDITION VASRD CODE RATING Chronic Back Pain, Status Post L5-S1 Fusion with Lower Extremity Neuropathy Manifested by Numbness and Absent Right Achilles Reflex 5299-5295 20% COMBINED 20% The following documentary evidence was considered: Exhibit A.
