Dr. Jones ANALYSIS:
4/25/01 DATE OF FILMS: 2/14/01 REPORT: 4/25/01 RADIOGRAPHIC BIOMECHANICAL REPORT This report is based upon biomechanical analysis and
protocols that have been established for roentgenological digitization
of the spine. This evaluation
will not include a pathological report.
Radiographs used were of acceptable quality and in compliance
with normal protocols for x-ray digitization.
This report is based on the digitization printout. AP and Lateral Cervical Spine: There are abnormal AP and lateral baselines.
Cobb’s angle is measured at C6/C2=10.6 degrees (RT).
AP Stress lines indicate 14.9 degrees of displacement.
Abnormal vertebral body rotation is seen in the upper cervical
spine. Cervical Lordosis is
diminished due to an increased fixed anterior/superior Occiput and an
altered Atlas/Axis angle. Normal
range of Occiput movement is 7 degrees in flexion and 7 degrees in extension. (See Occiput Angle, Extension View). Interruptions of George’s Line at C2/C3, C3/C4, C4/C5, C5/C6 and
C6/C7 are indicative of Ligamentous laxity.
Jackson’s angle demonstrates hypolordosis and there appears to
be abnormal lateral stress lines at C4/C5.
Cervical Stenosis appears to be reduced by 2.5mm or greater,
which indicates a (Grade I) Stenosis; C3, C4, C5 and C6 nerve root may
present significant neurological findings.
There is abnormal lateral Vertebral Offset at C3 and C2. AP Thoracic Spine: There are abnormal AP baselines. Cobb’s angle is measured at T12/T5=26.8 degrees (RT) and T4/T1=13.1 degrees (LT). Abnormal vertebral body rotation is seen in the upper and lower thoracic spine. AP and Lateral Lumbar Spine: There are abnormal AP and lateral baselines.
Cobb’s angle is measured at SR/L1=14.5 degrees (LT).
The AP sacral angle is altered 4.5 degrees (RT).
Abnormal vertebral body rotation is seen in the mid lumbar spine. Scoliosis is indicated in the lumbar spine.
Ferguson’s angle appears to be increased.
There are interruptions of George’s line at L1/L2, L2/L3, L3/L4,
L4/L5 and L5/S1 indicative of ligamentous laxity.
There is an abnormal line of weight bearing to the anterior.
There is abnormal Lateral Offset at L1, L2, L3, L4 and L5.
IMPRESSIONS: 1.
Abnormal
straightening of the cervical spine. 2.
Cervical
(C7-C1) motion study indicates translational motion segment integrity
change at C4. The impairment
of the cervical region is due to loss of motion segment integrity and
is ratable at 25% for cervicothoracic spine (AMA Guides, Fifth Edition). This patient’s digital analysis reveals loss of motion integrity
at C4=4.2mm, yielding an impairment estimate based on plain film forensics
of 25%. 3.
Jackson’s
Angle appears to be compromised in Flexion and indicates a possible
focus of a fixation. 4.
Ligamentous
laxity is suggested in the cervical, thoracic and lumbar spine. 5.
Cobb’s
angle is measured at C6/C2=10.6 degrees (RT). 6.
AP
Cervical Stress lines indicate 14.9 degrees of displacement. 7.
George’s
Line is interrupted at C2/C3, C3/C4, C4/C5, C5/C6, C6/C7, L1/L2, L2/L3,
L3/L4, L4/L5 and L5/S1 indicative of ligamentous laxity. 8.
Cervical
Stenosis appears to be reduced by 2.5mm or greater, which indicates
a (Grade I) Stenosis, C3, C4, C5 and C6 and may have significant neurological
findings. 9.
Cobb’s
angle is measured at T12/T5=26.8 degrees (RT) and T4/T1=13.1 degrees
(LT). 10. Increased lateral sacral angle with abnormal
weight bearing to the anterior. 11. Cobb’s angle is measured at SR/L1=14.5 degrees
(LT). 12. The AP sacral angle is altered 4.5 degrees (RT).
13. Lateral Vertebral Offset at C3 and C2=4.3 degrees,
which is a ratable impairment at 4% whole body. 14. Lateral Vertebral Offset at L1, L3, L4, L5 and
L2=5.1mm posterior, which is a ratable impairment at 5% whole body. Kenneth J. Ratajczak, MD Certified by the American Board of Radiology |
