Os talonavicular dorsal

from Wikipedia, the free encyclopedia
Os talonaviculare dorsale between talus ( talus ) and navicular (scaphoid)

The os talonaviculare dorsale (from the talus : ankle bone ; os naviculare : scaphoid bone ; located dorsally on the (foot) back; also os supranaviculare , pirie bones , pirie ossicles ) is an additional bone at the tarsus .

Localization and diagnosis

Os talonavicular dorsale (marked on the left in the picture)

The dorsal talonavicular bone is usually triangular and lies in the joint space between the talus and the navicular bone on the upper edge of the dorsum of the foot. It is one of the more common extra bones ( prevalence 1.6%). The ossicle can occur either separately or with connection to neighboring bones. It is to be differentiated from fractures and bones of the talus or navicular bone or from tears in the ligaments of the joint between the ankle and scaphoid bone, which are associated with fractures ( avulsion fracture ). The diagnosis is supported by the fact that the dorsal talonavicular bone usually (but not always!) Occurs on both sides. In a 1956 paper, 24 corresponding findings in 783 examined feet are reported, with the finding being double-sided three times. Of the 14 cases reported by Pirie in his original papers, four were bilateral.

Usually this additional bone is symptomless and is only discovered as an incidental finding. In very rare cases, however, it can also lead to problems such as painful inflammatory conditions, especially on neighboring tendons. Treatment is either conservative, for example with tape bandages and adapted footwear, or by surgical removal of the bone. An existing dorsal talonavicular bone can promote a fatigue fracture of the navicular bone ( predisposition ).

First description and naming

X-rays by A. Howard Pirie, published 1921

There are different details for the initial description. On the one hand, Hyrtl (1860) is mentioned, who described the supranavicular bone as the processus trochlearis ossis scaphoidis , and Pirie (1921) is also frequently mentioned. Already in response to the article by A. Howard Pirie from Montreal (Canada) in 1921, Morris I. Bierman referred to the work of Hyrtl in 1922 and stated that the bone he describes was not the one Pirie describes, act. He also refers to Pfitzner, who described an ossicle with a corresponding localization as "supranavicular (spurium?)". He concludes, "Personally I believe that 'supranaviculare' is a good descriptive name for this rare ossicle."

The name Os supranaviculare goes back to E. de Cuveland on Pfitzner (1896), while Trolle (1948) chose the name Os talonaviculare dorsale . E. de Cuveland interprets this as the endeavor to "assign the element neither to the talus nor to the navicular."

To the naming (English) Pirie bone there is also the reference to the Scottish radiologist George A. Pirie (1864-1929).

Pirie's Bone in Anglo-Saxon Literature

In Anglo-Saxon literature, Pirie's bone is often used for the supratalare bone , i.e. an accessory ossicle on the talus (!). In the boundaries of the normal ... (2001) it says: "Probably the Pirie's bone actually corresponds to the supranavicular bone, as [...] was noticed after studying the original work by Pirie."
