Occurrence of degenerative joint disease in the radius: analysis of skeletal remains from the Poole-Rose ossuary
Bibliographic record
Abstract
This study focuses on radii excavated from the Poole-Rose ossuary and analyzes the occurrence and patterning of degenerative joint disease (DJD) on the proximal and distal joint surfaces. The Poole-Rose ossuary, located in eastern Ontario, is dated to A.D. 1550 +/- 50. The Poole-Rose population, dating to the Late Woodland period, were agricultural in their subsistence activities. The disarticulated patterning of the skeletal remains suggests this site was associated with the “Feast of the Dead,” a mass interment burial ceremony. This ceremony took place about every eight to twelve years. Frequencies of lipping, porosity, and eburnation were reported in degree of severity for the proximal and distal joint surfaces. The results of this study are comprised of qualitative and quantitative analyses, including frequencies and co-occurrences of degenerative changes by joint surfaces. These results indicate that a combination of stress factors and possibly systemic factors are involved and responsible for the onset of DJD. Pitting alone appears to represent initial changes, while lipping and eburnation, most often accompanied by pitting, represent the more moderate and severe cases. Generally speaking, pitting is the most frequent characteristic of DJD, proximal lipping is less frequent than distal lipping, and eburnation occurs in about 3.5% of all specimens. The results of cross-tabulations indicate a statistically significant relationship between lipping and pitting on each joint surface, with the distal joint surface being affected more frequently by degenerative changes. Eburnation occurs in every case with lipping and pitting. Occurrence of degenerative changes suggests no statistically significant differences between the left and right sides. The Poole-Rose population was not subjected to severe levels of mechanical stress that might aggravate the onset of DJD or its initial changes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
