AHN Orthopaedic Institute's Hand and Upper Extremity Division is a nationally recognized program delivering advanced care for upper extremity conditions, including complex shoulder pathology. 

Clinicians can now refer patients to AHN’s first fellowship-trained shoulder and elbow surgeon, Lucas Haase, MD, who practices at AHN Jefferson Hospital and AHN Bethel Park Health + Wellness Pavillion to diagnose and treat the full spectrum of shoulder conditions.

Why choose AHN for specialized shoulder care?

Clinicians should consider referral to shoulder specialists in AHN’s Hand and Upper Extremity Division for access to:

  • Unmatched expertise – The AHN Hand and Upper Extremity Division is comprised of fellowship-trained experts focusing exclusively on upper extremity conditions, ensuring advanced knowledge and experience across a range of hand, wrist, arm, elbow, and shoulder disorders. 
  • State-of-the-art-care – AHN surgeons were the first in Pennsylvania to use ExactechGPS® technology for added precision in shoulder replacement. Our team employs minimally invasive and subscapular sparing techniques to support faster recovery and reduced risk in treating arthritis, acute trauma, and various forms of bone cancer and disease. 
  • Comprehensive solutions – From rotator cuff repair to total shoulder arthroplasty, AHN specialists manage even the most challenging cases.
  • Collaborative approach – AHN’s integrated network offers advanced imaging, on-site physical therapy, and seamless communication with referring providers to coordinate care from diagnosis through rehabilitation.
  • Proven results with high-profile athletes – The division includes sports medicine subspecialists trusted by the Pittsburgh Pirates and Pittsburgh Riverhounds to manage sports-related and shoulder overuse injuries.“

No case is too complex,” said Dr. Haase. “AHN has both the expertise and the resources to support referring clinicians and deliver the right care for each patient.”

Optimal candidates for specialized care

Providers are encouraged to refer patients at any stage of care, including for second opinions. Evaluation by Dr. Haase and the Hand and Upper Extremity Division may be particularly beneficial for:

  • Patients requiring revision arthroplasty or advanced reconstructive procedures
  • Patients with recurrent instability or complex fractures
  • Younger patients with rotator cuff disease or those needing tendon transfer procedures

“It’s never too soon to refer a patient for additional examination or support,” said Dr. Haase. “We can provide timely diagnostic workups and collaboration across subspecialties to ensure each patient’s case is evaluated from multiple clinical perspectives, optimizing patient outcomes.”
