Thomas George Morton

Thomas George Morton (1835-1903) portrait 2

Thomas George Morton (1835-1903) was an American general surgeon and orthopaedic surgeon

Morton spent more than four decades associated with Pennsylvania Hospital, becoming surgeon in 1864, and founded the Philadelphia Orthopaedic Hospital in 1867. He also served as an Acting Assistant Surgeon in military hospitals during the American Civil War and later became a prominent surgical teacher and hospital administrator.

Morton is best remembered for his 1876 description of the painful forefoot syndrome subsequently termed Morton metatarsalgia, Morton neuralgia and Morton neuroma. His original explanation centred on pain around the fourth metatarsophalangeal articulation with suspected plantar digital nerve compression. The modern concept of a fibrotic interdigital nerve lesion developed through later anatomical, operative and pathological work.

He also made an important contribution to the emerging surgical treatment of acute appendicitis. In 1887 Morton performed the first recorded appendicectomy for acute appendicitis in which the patient survived. Morton subsequently advocated active exploration and removal of the diseased appendix and reported a series of seven operations for perforative appendicitis in 1890

Medical Eponyms
Morton neuroma, Morton metatarsalgia (1876)

1876 – Morton described 16 patients with a distinctive painful forefoot syndrome in A peculiar and painful affection of the fourth metatarso-phalangeal articulation. Severe paroxysmal pain was typically localised around the fourth MTP region and provoked by walking or pressure from footwear. Although Morton suspected “neuroma or some nerve hypertrophy”, his mechanical model centred on compression around the lateral metatarsophalangeal articulations.

The disorder subsequently became known as Morton metatarsalgia, Morton neuralgia and ultimately Morton neuroma. Modern Morton neuroma is understood as a chronic compressive neuropathy with perineural fibrosis rather than a true neoplasm, and its anatomical and pathological history substantially predates and postdates Morton’s own description.

In March, 1873,  was asked to see Miss H.S., aged 26 years, who while in Europe four years before, had injured her right foot by stepping upon a small stone. She said that she had at once experienced intense pain, which was soon followed by slight swelling and redness…The pain was referred to the head of the fourth metatarsal bone.

Key Medical Contributions
Appendicitis and appendicectomy

1887 – On April 27, Morton performed the first successful appendicectomy for acute appendicitis. Morton operated on a 26-year-old man with a three-day acute illness and generalized purulent peritonitis. At laparotomy he encountered an abscess around the caecum and a perforated diseased appendix, with a phosphatic concretion lying beside the perforation. He ligated and excised the appendix, the patient recovered uneventfully and remained well at follow-up.

This was not the first appendicectomy. Tait had removed a gangrenous appendix through an abdominal incision in 1880, and Krönlein performed the first operation specifically for acute appendicitis in 1884, although his patient died. Morton’s distinction is therefore the first recorded intentional appendicectomy for acute appendicitis followed by survival.

1888 – In diagnosis of pericæcal abscess, and its radical treatment by removal of the appendix vermiformis, Morton argued that most disease then labelled typhlitis, perityphlitis or pericaecal abscess arose from the appendix, stating that “pericaecal disease may… in most cases, be said to mean disease of the appendix vermiformis.”

1890 – Morton consolidated his experience in Inflammation of the vermiform appendix: its results, diagnosis and treatment, reporting seven cases of excision for perforative appendicitis, with five surviving. He advocated identifying and excising the appendix whenever disease was found rather than merely draining the surrounding abscess.

Laparotomy for perforative appendicitis, with removal of the organ, is now an established surgical procedure, and yet so recently has this operation been introduced that I am able to present the patient upon whom I operated in April, 1887, for pericecal abscess with peritonitis, which I believe represents the first successful operation for the removal of the vermiform appendix in a case of this kind, based upon correct diagnosis.
