On December 6, 2002, this 46 year old claimant injured his right shoulder while attempting to close off a water hydrant. As he pulled forcefully on the wrench, the claimant felt a "pop" and severe pain in his right mid-clavicle with pain, numbness, and tingling radiating into his hands and fingers. The claimant's wife drove him home from work where he rested for the weekend while applying heat and ice to the painful area. The pain worsened however, and he reported his injury when he returned to work.
The claimant went to Unity Corporate Health, and on December 9, 2002, x-rays revealed a fracture of multiple screws holding the stabilization bar of his right shoulder and a united fracture of the mid aspect of the right clavicle. He consulted Dr. Pierron, an orthopedic surgeon, who put the claimant on light duty due to a failure of the internal fixation of his non-union right clavicle. On January 14, 2003, Dr. Pierron performed an open reduction internal fixation with Flexon bone graft to the right clavicle non-union. See Exhibit A. Dr. Pierron ordered physical

therapy. On May 6, 2003, Dr. Pierron recommended applying an Exogen bone stimulator to try
to boost the amount of new bone formation at the interface and that the claimant delay
unrestricted heavy physical labor until he developed better bone. On June 16, 2003, Dr. Pierron
ordered an exercise program with a one to two pound progression per week. On August 4, 2003,
Dr. Pierron found that the claimant had pain when trying to lift more than three pounds due to the
persistent non-union fracture. On August 18, 2003 Dr. Pierron performed a bone marrow and
bone-void filler ignite injection to the right clavicle non-union. On September 22, 2003, the
claimant still had pain lifting over five pounds, popping around the shoulder blade and straining
and pulling on the muscles around the shoulder, and Dr. Pierron ordered additional physical
therapy. On January 12, 2004, x-rays showed persistent non-union, and Dr. Pierron opined that
additional surgical intervention was indicated. On February 16, 2004 Dr. Pierron performed an
open bone grafting with autograft, both cancellous and corticocancellous bone from the right
pelvis. The claimant had additional physical therapy after the surgical procedure.
On August 2, 2004, Dr. Pierron examined the claimant and found shoulder instability and
persistent pain. The claimant reported shooting pains and numbness in his arm and Dr. Pierron
opined that further surgery was only indicated in the event of failure of the plate and/or screws.
On August 10, 2004, an EMG revealed bilateral carpal tunnel syndrome with loss of the sensory
nerve function with the maintenance of the other nerves involved in the brachial plexus. On
August 30, 2004, Dr. Pierron examined the claimant and found that the claimant had a 30%
weaker shoulder in the right compared to the left. He had significant pain and limitation of
motion and radiographic incomplete healing of the clavicle non-union and needed to continue
with physical therapy. On September 27, 2004, the claimant had increased swelling around the
right clavicle and shoulder and residual weakness of the right scapula. X-rays revealed loosening
around two of the three lateral screws without failure of the plates. The claimant continued the
ultrasound stimulation and physical therapy. On November 29, 2004, Dr. Pierron examined the
claimant and found that the claimant had more pain with increased shoulder activity, radiating
pain around the shoulder itself, and clicking behind the shoulder blade. There was snapping of
the scapula not directly related to his clavicle other than the residual weakness and change in the
muscular balance of the shoulder after prolonged limitation of use of the right upper extremity.
On November 29, 2004 Dr. Pierron opined that no further surgical intervention was indicated,
because the claimant had not had complete failure of the hardware. Dr. Pierron opined that the
claimant had reached maximum medical improvement “to date.”
On March 7, 2005, Dr. Pierron examined the claimant and found loosening and continued
motion of the screws. The claimant could not return to physical labor activities that require
forceful use of the right arm. On July 25, 2005, the claimant reported increasing pain during a
long drive. On March 20, 2006, Dr. Pierron indicated that if the x-rays showed complete failure
or fracture of the screws, then the claimant would need surgery for the revision of the internal
fixation hardware. On April 12, 2006, the claimant had a nerve conduction study of the right arm
which showed chronic degeneration in the C6-7 and 8 innervated muscles consistent with mild,
early median neuropathy at the wrist/carpal tunnel and suggestive of chronic mild middle cervical
radiculopathy. On May 3, 2006, Dr. Pierron took x-rays that revealed a failure of the plate with
distal screws pulling up allowing the plate to disassociate from the distal clavicle. Dr. Pierron, at
that time, suggested repeat surgery. Dr. Pierron also indicated that the chronic nerve
degeneration from the neck was probably causing numbness. The claimant did not want to
consider cervical surgery at that time. On May 23, 2006, Dr. Pierron performed a surgical
