Louis Arnold Gilula (1942-2014) portrait

Louis Arnold Gilula (1942-2014) was an American radiologist

Gilula was a pioneer of musculoskeletal and wrist imaging. He spent 40 years at the Mallinckrodt Institute of Radiology (MIR), Washington University School of Medicine, where he became professor of radiology, orthopaedic surgery, plastic and reconstructive surgery.

Gilula is best remembered for his systematic approach to carpal radiography with the Gilula carpal arcs, described in 1979. He also contributed to early interventional radiology, image-guided treatment of spinal pain, vertebroplasty and other percutaneous procedures.

Biographical Timeline
  • Born on October 21, 1942 in Lubbock, Texas son of Dr Adolph and Dora Gilula
  • 1967 – Graduated MD from the University of Illinois School of Medicine, Chicago. Completed internship at San Francisco General Hospital.
  • 1968–1970 – Began radiology training in St Louis but was drafted after six weeks of residency. Served as a Captain in the United States Army, with postgraduate training at DeWitt Army Hospital, Fort Belvoir, Virginia.
  • 1970–1973 – Returned to St Louis and completed radiology residency at St Louis City Hospital (Max C. Starkloff Memorial Hospital).
  • 1973 – Joined the Mallinckrodt Institute of Radiology (MIR), Washington University School of Medicine. Over the following 40 years he rose to professor of radiology, orthopaedic surgery, and plastic and reconstructive surgery, and headed the musculoskeletal section for 24 years.
  • 1979 – Published Carpal injuries: analytic approach and case exercises, introducing the three radiographic carpal arcs that subsequently became known as Gilula arcs.
  • Co-founded the International Wrist Investigators Workshop and was its only radiologist member. With hand surgeon Julio Taleisnik, helped guide the Workshop for more than two decades as an international forum for wrist research.
  • 1992 – Consolidated his work on midcarpal arthrography, carpal instability, ulnar translation, wrist fractures and degenerative disease in his textbook The Traumatized Hand and Wrist: Radiographic and Anatomic Correlation.
  • 2008–2010 – Recognised repeatedly for teaching at MIR. Distinguished Teacher of the Year (2008/2009) and Teacher of the Year in 2010.
  • 2013 – Retired from Washington University in October after approximately 40 years at Mallinckrodt. The department conference room was dedicated as the Louis A. Gilula, MD Conference Room in recognition of his contribution to education and training.
  • Died July 2, 2014 aged 71, following pancreatic cancer in Ladue, St. Louis County

Medical Eponyms
Gilula carpal arcs (1979)

Gilula’s three carpal arcs are assessed on a posteroanterior wrist X-ray. They represent the smooth cortical contours formed by the proximal and distal carpal rows. Gilula developed the system after reviewing over 90 carpal fractures and fracture-dislocations between 1973 and 1978.

In the normal wrist, small indentations may occur where adjacent bones meet, but the overall curvature should remain smooth. Gilula emphasised that interruption of an arc should prompt careful examination of the corresponding joint or bone.

In the analysis of these cases, it became evident that on the posteroanterior radiograph, three fairly smooth radiographic arcs could be drawn to define normal carpal bone relationships (fig. 1 ). Break of any of these arcs strongly suggests abnormality at the site of the broken arc.

Arc I follows the main convex curvatures of the proximal surfaces of the scaphoid (navicular), lunate, and triquetrum carpal bones. Arc II outlines the distal concave curvatures of these same three bones. Arc III traces the main proximal curvatures of the capitate and hamate.

Arc I (blue) follows the proximal convex margins of the scaphoid, lunate and triquetrum;
Arc II (red) follows the distal concave margins of the same three bones; and
Arc III (green) follows the proximal convex margins of the capitate and hamate. The arcs should form smooth curves without a major step-off.

1996 – Wilfred C. G. Peh and Gilula examined Normal disruption of carpal arcs in 100 asymptomatic wrists. They found that Arcs I and II may normally become disrupted during radial or ulnar deviation, while they are usually continuous in a neutral wrist. Arc III remained intact in all positions studied. They concluded that wrist positioning must be considered before interpreting disruption of Arcs I or II as pathological.


Key Medical Contributions
Interventional radiology and treatment of spinal pain

Gilula was an early contributor to interventional radiology. His work included angiography of haemodialysis arteriovenous fistulas, catheter-directed thrombolytic therapy, therapeutic spinal injections and other image-guided percutaneous procedures. He became an early adopter and investigator of vertebroplasty, and published on its indications, contraindications and technique.

His clinical practice included vertebroplasty, kyphoplasty, cementoplasty, radiofrequency treatment of painful osseous lesions and image-guided management of chronic spinal pain. Washington University later described him as a pioneer who offered therapeutic spinal injections before such treatment became commonplace.

Teaching and scholarship

Gilula regarded teaching as a central part of his career. During his 40 years at Mallinckrodt he taught generations of radiology residents and fellows, receiving repeated institutional teaching awards and, on retirement, having a departmental conference room named in his honour. He authored more than 300 peer-reviewed articles, two textbooks, and numerous chapters, reviews and case reports.
