“…Antón & Polidoro (2000) similarly described a unilateral case of CRUS from an undesignated location on Santa Rosa Island California, seen in the right radius and ulna of an adult of unknown sex. Antón & Polidoro (2000) also presented an interesting bilateral example from an undesignated location in Marin County, California. The radii and ulnae of an adult male are described as being functionally fixed in a semi-pronated and partly flexed position, but without bony fusion.…”

“…The radial heads of this individual are domed, the radial shafts bow antero-laterally, the ulnar shafts have a slender or wasted appearance, and the forearms are fixed in a semi-pronated position (Reed, 1981;Antón & Polidoro, 2000).

“…CRUS has also been found in association with cardiovascular, genitourinary, gastrointestinal, and central nervous abnormalities (Rizzo et al, 1997;Bhatt & Mehta;Capra et al, 2009;2011:237) Although the etiology of CRUS is not clear, there appears to be a genetic basis as there have been clinical examples of dominant inheritance and positive family history (Hansen & Andersen, 1970). In non-syndromic cases, it appears to be autosomal dominant whereas syndromic cases may be autosomal dominant with incomplete penetrance (Cleary & Omer, 1985;Rizzo et al, 1997), autosomal recessive (Antón & Polidoro, 2000;OMIM, 2002;Sirmaci et al, 2010;Panigrahi, 2011), or potentially X-linked dominant (Capra et al 2009) as in the case of Giuffrè-Tsukahara syndrome (Dalal et al, 2010). When it is an isolated case, the anomaly may be the result of a sporadic mutation (Cleary & Omer, 1985:539).…”

“…It appears that individuals with the condition adapt by increasing their range of movement through compensatory motions at the shoulder and wrist (Cleary & Omer, ; Blauth & von Rothkirch, ; Bhatt & Mehta, ). Indeed, in their analysis of skeletal remains with CRUS, Antón & Polidoro () observed a more pronounced Lister's tubercle (dorsal tubercle) of the radius that likely resulted from compensatory movement of the wrist (e.g. greater extension).…”

A rare example of congenital radioulnar synostosis was observed in a sample of 160 male, female, and juvenile Lambayeque (Sicán) skeletons excavated from Huaca Cao Viejo, a mud brick platform mound built during the Early Intermediate Period and later utilized by a Late Intermediate Period Lambayeque population (ca. AD 950-1250) for interments. The affected individual was a young female, estimated to be 16-18 years of age at the time of death. To date, this is the first case of congenital radioulnar synostosis to be described from an archaeological context in South America, and one of 13 reported archaeological cases worldwide.

The forearm skeleton is composed of two bones: the radius and the ulna. This is closely related to manipulative movements. The ulna is part of the elbow joint, whereas the radius and ulna together with the scaphoid and lunate bones, form the wrist joints. Thus, morphofunctional analysis of the adult Sima de los Huesos (SH) forearm bones, provides clues about manipulative activities in one Pleistocene population. From 1976 to the present, over 7000 human fossils have been recovered from the SH site. The radial sample comprised 98 labeled fragments, of which 49 belonged to adult individuals, representing at least 7 individuals. The ulnar sample included 31 labeled adult fossils representing at least nine individuals. In this study, we describe the SH radii and ulnae and analyze their functional implications for manipulative and forearm movements. We confirmed that the SH radii are long and curved, with variations in robusticity and radial tuberosity orientation. The SH ulnae are characterized by an anteriorly oriented trochlear notch, a massive olecranon process, an obliquely oriented radial notch, a blunt and short supinator crest, a gracile and curved diaphysis, and a round and anteriorly oriented pronator crests. In general, they exhibit Neanderthal morphology. The SH collection provides a unique opportunity to conduct morphological analyses of these bones in the Middle Pleistocene population.

Congenital synostoses are defined as rare abnormal formations of primary anatomical structures. There are three major classifications: (a) skeletal anomalies, (b) soft tissue anomalies, and (c) anomalies involving both skeletal and soft tissues. Radioulnar synostosis is the most common form of upper limb abnormality. Synostoses between the humerus and either the ulna, radius, or both have been documented but are far less common. Of these cases, the most common type is humeroradial synostosis followed by humeroradioulnar and humeroulnar synostosis. This study presents a case of a late medieval (15th–16th c. A.D) adult male skeleton housed at the Hirszfeld Institute of Immunology and Experimental Therapy of the Polish Academy of Sciences with bilateral upper limb synostosis. Macroscopic and radiographic analyses suggest a diagnosis of congenital humeroradioulnar and humeroulnar synostosis. The right radius and ulna are hypoplastic. The left radial neck was reduced. The left radial head and the radial notch of the left ulna were absent. The radiographs demonstrate that the skeletal structures of the elbow are absent, suggesting fusion of the radius and ulna. A review of the clinical and bioarchaeological literature was conducted to assess differential diagnoses for the conjoined humerus, radius, and ulna. To the best of the authors' knowledge, this is the first case of congenital humeroradioulnar synostosis in the paleopathological literature.
