Harry Raymond Eastlack

In the 2009 film inspired by Edgar Allan Poe's "The Tell-Tale Heart", Tell-Tale, Eastlack is mentioned and referred to as Harry Erlich. The mention occurs in a scene where characters are in a museum, and a skeleton is referred to. The scene provides some genuine facts, such as how Eastlack's skeleton does not require any wiring or glue to be held together in the museum because the fused bones hold it all in one piece.

Eastlack's home, Philadelphia, has become a center for FOP research with much of it concentrated at the University of Pennsylvania. With his skeleton on display, doctors and professors alike lead students to the Mütter Museum to observe the result of the rare disorder in person. Since surgeries and examinations of FOP patients exacerbate the condition, the ability to study Eastlack's skeleton has been significant for research. For example, in 2006, University of Pennsylvania's team of researchers and scientists led by Frederick Kaplan was able to distinguish the particular gene responsible for the disease, the ACVR1 gene. It is said that Eastlack's skeleton was a useful reference for this medical discovery. The International FOP Association is also granted Eastlack's skeleton for displaying and informational purposes in medical meetings and international FOP symposia, which physicians, researchers, and patients attend. For example, over 43 families were recorded to have attended a two-day symposium hosted in Philadelphia in October 1995 to listen to orthopedic surgeons and physicians discuss the details of FOP. During this symposium, Eastlack's skeleton was used as a reference. After seeing his skeleton at this event, fellow FOP patient Carol Orzel decided to also donate her body to the museum. She died in February 2018, and in February 2019, her skeleton was put on display next to his.

Eastlack died at the Inglis House for the Incurables—a care home dedicated to attending low income, physically disabled individuals. As he approached the later stages of his life, he required assistance to stand and used a cane to be able to shuffle. During his time there, his right leg broke and is said to have healed at an odd angle. Consequently, he spent years bedridden and developed bronchial pneumonia from the physical inactivity. Due to the ossification on his ribs, his lungs could not expand well and this inhibited his ability to cough. Near the time of his death, Eastlack told his sister, Helene, that he desired to donate his body and medical records to research, so that the disease may be further investigated and understood. On November 11, 1973, just six days shy of his 40th birthday, he died of pneumonia.

Eastlack's case of FOP progressed at a more rapid rate due to the number of intrusive surgeries he underwent. In 1948, at the age of 15, his jaw had become fused so he could no longer eat solid food and had to speak through clenched teeth. At a young age he faced difficulty sitting down, as well. His hips were one of the first anatomical parts to become immobilized due to heterotopic ossification. Soon, bone formed across his upper arms and extended onto his sternum, tying his arms to his breast. Sheets of bone spread along his back and ribbons of bone extended from there to his skull, inhibiting proper head movement. The new bone growths throughout the years also caused juts of bone to form on his pelvis and thighs, and it caused both of his feet to become clubbed. One year he accidentally bumped his buttocks into a radiator, and this resulted in a bruise wherein the smooth tissue was destroyed and gave way to newly formed bone. Ultimately, the only mobility that Eastlack had left was that of his eyes, lips, and tongue.

Unaware of the consequences of surgery on an FOP patient, the physician admitted Eastlack for hip surgery in 1941 which caused further physical restriction. Over time Eastlack became more and more immobilized as more joints became fused and newly formed sheets or strings of bone calcified his limbs. In 1944 he was readmitted for a study which confirmed that the calcified smooth muscles, tendons, and ligaments had indeed become mature bone. The ossification along his vertebrae and other anatomical parts that Eastlack would suffer in the next 29 years ultimately fused him into a permanently bowed position.

In attempts to diagnose and treat Eastlack's condition, the doctors ordered biopsies and performed a total of 11 surgical procedures to remove excess and heterotopic ossification, such as that on his thigh muscles. However, Eastlack's condition was aggravated by such procedures and the bone plates returned thicker and more predominant. It was 1938, the year after the incident, when he was finally diagnosed with Myositis ossificans progressiva, which is now known as Fibrodysplasia Ossificans Progressiva (FOP).

As is characteristic of FOP patients, Eastlack did not demonstrate any possible sign of a disease at birth except for a malformation of the big toes. At the time it was not recognized as the first clinical sign of FOP. It was not until 1937 when the first heterotopic ossification symptom surfaced. By the time of his death, Eastlack's skeleton bore sheets of bone along the vertebrae, which fused to and locked his skull, and branches of bone along his limbs, which immobilized his shoulders, elbows, hips, and knees. He died in Philadelphia of bronchial pneumonia six days before his 40th birthday.

Harry Raymond Eastlack, Jr. (17 November 1933 – 11 November 1973) was the subject of the most recognized case of FOP (fibrodysplasia ossificans progressiva) from the 20th century. His case is also particularly acknowledged, by scientists and researchers, for his contribution to medical advancement. After suffering from a rare, disabling, and currently incurable genetic disease, Eastlack decided to have his skeleton and medical history donated to the Mütter Museum of the College of Physicians of Philadelphia in support of FOP research. His skeleton is one of the few FOP-presenting, fully articulated ones in existence, and it has proved valuable to the study of the disease.

Harry Eastlack was born on November 17, 1933 at 10:24 AM in the Woman's Hospital of Philadelphia. There are no reports of any difficulties during his delivery, though there was the observation of a minor congenital malformation. The noted malformation was his congenital bilateral hallux valgus, oftentimes referred to as a bunion.
