The church burials of Room-94 and Church-79 as well as the Tower 35-Tomb were excavated within the ancient Byzantine settlement in Khirbet es-Samrā, North Jordan. They were initially dated between the 7th and 9th centuries AD. The report provides the results of macroscopic analyses of the obtained human skeletal remains. These include demographic, anthropometric, epigenetic, and pathologic features. The available biological and archaeological evidence tend to suggest that the five adults and child buried in Room-94 tomb were related males, possibly of one local and highly positioned family that was associated with the adjacent Church 95. The six were successively buried in the “private” tomb in Room-94 of Church-95 and not in the “public” cemetery just outside the settlement. The two probable cases of brucellar lesions on the cervical vertebrae of two adults could be indicative of an animal breeding family and that dairy products were part of the local diet. The report also suggests a possible relatedness between Room-94 tomb burials and the 7th century AD senile female burial in Church-79, which was previously assumed to be a male church-functionary burial. Despite being marked by a cross-engraved stone and a probably lethal arrow injury, the available evidence lead to conclude that the male Tower burial, previously identified as of the 9th century AD, was in fact a medieval burial and that it is neither related to the ancient settlement nor to its ancient population. Also presented are some rarely reported biological features, e.g. the “en bloc” manifestation of the transverse foramen division on the cervical vertebrae C5 to C7. Keywords: Jordan - Byzantine Period - Church Burial – Anthropometry - Epigenetics- Paleopathology.

“…Accessory ossicles of the foot are commonly confused for avulsion fractures of the foot, leading to misdiagnosis and overtreatment in cases of trauma. 1,5,6 OST was first described in 1804 by Rosenmuller. 2,7 OST is an accessory ossicle located posterolateral to talus; it has an incidence ranging from 2 to 25%.…”

“…It frequently occurs bilateral being common in soccer players, runners, and gymnasts, due to repeated plantar flexion of the ankle. 6,[8][9][10][11][12] It is predominantly symptomatic in men compared to women. 3 Repetitive dorsiflexion of the foots, metatarsophalangeal joint, and plantarflexion of the ankle, can result in FHL tendonitis, tenosynovitis.…”

“…Margins of OST are either smooth or serrated in appearance. 4,6 When triangular it presents with three surfaces anterior, inferior, and posterior. The anterior surface articulate with the lateral tubercle of talus by fibrocartilaginous synchondrosis, while the inferior surface articulate with calcaneum and the posterior surface forms non-articular area and provides attachment to posterior talocalcaneal and posterior talofibular ligaments one must be familiar with such normal anatomical variants in order to prevent their misinterpretation and overtreatment in cases of trauma and ankle sprain.…”

“…OST syndrome or posterior ankle impingement (PAI) results from blunt foot trauma and is usually associated with pain and tenderness at the ankle joint. [4][5][6][7] Knowledge regarding OST is important to identify the potential cause of posterior ankle pain and to decide on the conservative or surgical line of management. Hence, a radiographic study on OST was done to determine the incidence, morphology, and distribution of OST in the foot radiographs and has been reported for its clinical significance.…”

Background: Os trigonum (OST) is commonly located on the posterior aspect of the talus. It occurs as a result of secondary ossification center failing to fuse with the lateral tubercle of the posterior process of the talus; its incidence varies between 2 and 25%, and is more often bilateral. It occurs as an intra-articular Os, which is most often securely rooted to the lateral tubercle of the talus by a fibrocartilaginous synchondrosis. Aims and Objective: To determine the incidence, morphology, and distribution of Os Trigonum (OST). Materials and Methods: Retrospective 500 lateral foot radiographs view were studied to determine the incidence, morphology, and distribution of OST. Results: Incidence of OST in the present study was 6.6%, with predominantly round or ovoid in shape. OST was located on the posterolateral aspect of the talus. Conclusion: OST can be one of the causative factor responsible for Flexor hallucis longus tendonitis, OST syndrome, which occur in plantarflexion of the ankle, leading to compression of the OST between the distal tibia and the calcaneus. Hence, knowledge regarding the incidence, morphology, and distribution of OST is important for the radiologist, orthopedic surgeons to arrive at a correct diagnosis, which aids in the management of cases presenting with complaints of posterior ankle pain.

Objectives: This study investigated the effect of two portal posterior ankle arthroscopy (PAA) procedures using American Orthopaedic Foot and Ankle Society (AOFAS) and Visual Analog Scale (VAS) scores for the treatment of patients with ankle pain associated with Os trigonum (OT) and Flexor hallusis longus (FHL) tenosynovitis. The effect of PAA treatment on the degree and localization of effusion around the FHL tendon was also investigated. Methods: Between March 2016 and August 2021, 41 patients who underwent PAA with the diagnosis of OT and stenosing FHL tenosynovitis, whose arthroscopy video records could be reviewed retrospectively, and who had at least 1 year of follow-up results were included in the study. Patients in the pediatric age group, diabetes patients, patients with inflammatory disease, and those with subtalar and tibiotalar osteoarthritis were excluded from the study. Preoperative and postoperative physical examinations, lateral radiography of the pressing foot, MRI, and the VAS and AOFAS scores were evaluated. In the statistical analysis, data were statistically analyzed using SPSS 19.0 (SPSS, Chicago, Illinois, USA). p < 0.05 was accepted as statistically significant. Results: The mean age was 35.6 years (range: 19-55), among which the mean age of the women was 36.2 years (range: 24-48), and the mean age of the men was 35.2 years (range: 19-55). The mean follow-up was 34 months (range: 14-62). The AOFAS value increased from 38.61 ± 7.176 preoperatively to 89.83 ± 6.34 at the postoperative follow-up, and the difference was statistically significant (p < 0.001). Five patients fully regained their normal function (AOFAS score = 100 points). The VAS value increased from 90 ± 5.916 preoperatively to 18.682 ± 7.688 at the last postoperative follow-up, and the difference was statistically significant (p < 0.001). Pre-PAA FHL tenosynovitis was seen only in zone 1 in 26 patients, zones 1 and 2 in 14 patients, and in zones 1, 2, and 3 in two patients. There was no significant decrease in effusion in the magnetic resonance imaging (MRI) at 1 month after the PAA (p = 0.117). A significant decrease in effusion was observed in the MRI taken at the last control (p < 0.001). Conclusions: In the treatment of patients with ankle pain associated with OT and FHL tenosynovitis, the two-portal PAA treatment was observed to be an effective method that resulted in significant improvement in the AOFAS and VAS scores.
