TRACEE MAWYER vs. GALLO GLASS COMPANY

This case involves Tracee Mawyer's workers' compensation claim against Gallo Glass Company for cumulative trauma injuries. The Appeals Board granted reconsideration, reversing the trial judge's denial of injury to applicant's bilateral upper extremities, specifically carpal tunnel syndrome. The Board found Dr. Clayman's reports sufficiently supported an industrial injury to the upper extremities and awarded additional temporary disability for the period following carpal tunnel surgery. The case was returned for a new permanent disability rating for the upper extremity injuries.

John Cummins vs. VIP Limousines \& Coaches, Inc., Commerce and Industrial Insurance Company, Barrett Business Services, Inc.

This case involves an applicant who claimed injury to multiple body parts, including upper extremities, back, neck, abdomen (hernia), and lower extremities. The Workers' Compensation Appeals Board (WCAB) affirmed the original findings, except they specifically ruled against injury to the applicant's upper extremities based on the Agreed Medical Examiner's opinion. The WCAB also clarified that temporary disability benefits should commence from September 14, 2010, the date of hernia repair surgery, and deferred the determination of the exact date of injury for the cumulative trauma. The court also upheld the applicant's average weekly earnings determination, finding the applicant's testimony and records credible and unrebutted.

SEAN HARRIS vs. COAST CRANE COMPANY, EMPLOYERS INSURANCE OF WAUSAU, THUNDER MACHINE WORKS, AIX INSURANCE COMPANY, AEROTEK, ALLEGIS GROUP INSURANCE COMPANY OF THE STATE OF PENNSYLVANIA

This case concerns a petition for reconsideration by defendant Wausau regarding an arbitrator's findings that applicant sustained industrial injury to his pulmonary system and upper extremities during a cumulative period. Wausau argued the claim was time-barred and that liability for upper extremity injury was improper. The Board denied Wausau's petition, finding Wausau failed to meet its burden of proof on the statute of limitations defense. The Board also determined that applicant properly amended his claim for upper extremities and that apportionment of liability based on days worked was appropriate.

JOE CASILLAS vs. GRAYD A PRECISION METAL FABRICATORS; STATE COMPENSATION INSURANCE FUND

This case concerns a petition for reconsideration by the defendant regarding a permanent total disability award for Joe Casillas. The defendant argued against the total disability finding, questioned injury to the left upper extremity, and contested the basis for vocational rehabilitation findings. The Board granted reconsideration to amend the findings, rescinding the finding of injury to the left upper extremity due to the applicant unilaterally withdrawing that issue. However, the Board affirmed the permanent total disability finding based on substantial medical and vocational evidence, including the applicant's significant limitations in daily living and unsuitability for vocational rehabilitation, despite the absence of left upper extremity injury.

MARCIA FARRAR vs. STATE OF CALIFORNIA, UNEMPLOYMENT INSURANCE APPEALS BOARD, legally uninsured, administered by STATE COMPENSATION INSURANCE FUND

This case concerns defendant's petition for reconsideration of a Workers' Compensation Appeals Board (WCAB) finding of injury arising out of and occurring in the course of employment (AOE/COE) to the applicant's right upper extremity. Defendant argued that no evidence supported injury to other alleged body parts and that the WCJ should have made findings on those parts instead of deferring the issue. The WCAB denied reconsideration, affirming the WCJ's decision to limit the trial to the threshold issue of right upper extremity injury AOE/COE. The WCAB found Dr. Amster's opinion constituted substantial evidence for the right upper extremity injury and that the WCJ acted within their authority by deferring other issues.

NATIVIDAD URIAS vs. VISHAY TRANSDUCERS, LIBERTY MUTUAL INSURANCE COMPANY

This case involves a workers' compensation applicant seeking further medical treatment for admitted industrial injuries to her right shoulder and bilateral upper extremities. The Workers' Compensation Appeals Board granted reconsideration to clarify the scope of awarded medical treatment. The Board affirmed the need for a right carpal tunnel release surgery as recommended by the applicant's physician but reversed the award of arthroscopic shoulder surgery, finding it premature without a specific recommendation or request for authorization.

NANCY ANDREWS vs. LAW OFFICES OF KENNETH REYNOLDS, OAK RIVER INSURANCE COMPANY

This case involves a workers' compensation applicant who sustained industrial injuries to her back and upper extremities. The defendant sought reconsideration of a prior award, arguing they were not obligated to conduct utilization review or obtain a second opinion regarding a spinal surgery recommendation from Dr. Anderson. The Appeals Board denied the petition, finding the defendant failed to timely object or initiate the required processes after Dr. Anderson recommended the same surgery previously suggested by a second-opinion physician. The Board clarified that utilization review and second opinion obligations extend to any physician's treatment recommendations, not solely the primary treating physician.

WILLK MARILAO vs. CITY OF SHAFTER

Applicant Willk Marilao sought reconsideration of a Joint Findings of Fact and Award (F&A) concerning industrial injuries to his upper and lower extremities. The F&A found 64% permanent partial disability for upper extremities and 23% for lower extremities. Applicant contended that he was 100% permanently and totally disabled and that apportionment was improper. The Workers' Compensation Appeals Board granted the petition, rescinded the F&A, and returned the matter for further proceedings, finding the original findings of specific injuries unsupported by substantial medical evidence, and medical opinions on apportionment to be speculative.

Angel Mendez vs. Maple Dairy, Zenith Insurance Company

The Workers' Compensation Appeals Board denied Angel Mendez's petition for reconsideration. Mendez sought a finding of $100\%$ permanent disability, arguing total loss of use of his dominant right upper extremity. The Board affirmed the WCJ's prior award of $75\%$ permanent disability, finding no presumption of total disability for the loss of use of only one hand. The evidence did not support a finding of total loss of use of the upper extremity.

MICHAEL FEENEY vs. CITY OF ANAHEIM FIRE DEPT., permissibly self-insured

This case involves a fire captain's claim for industrial injury to his upper extremities, specifically bilateral carpal tunnel and canal of Guyon entrapments. The Workers' Compensation Appeals Board (WCAB) rescinded the previous award, finding insufficient evidence to support industrial causation for these specific upper extremity injuries. The WCAB remanded the case for further development of the record, as medical reports did not definitively link the conditions to his employment. The determination of permanent disability and apportionment for these issues remains deferred pending further medical evaluation.
