Abstract
Peak EL, Parvizi J, Ciminiello M, et al . The role of patient restrictions in reducing the prevalence of early dislocation following total hip arthroplasty. A randomized, prospective study. J Bone Joint Surg Am 2005;87–A:247–53.[OpenUrl][1][PubMed][2] Q In patients who have had uncemented primary total hip arthroplasty (THA), does removal of several postoperative functional restrictions (PFR) reduce the risk of postoperative dislocation? ### ![Graphic][3] Design: randomised controlled trial. ### ![Graphic][4] Allocation: not concealed. ### ![Graphic][5] Blinding: unblinded. ### ![Graphic][6] Follow up period: ⩾6 months ### ![Graphic][7] Setting: a university hospital in Philadelphia, Pennsylvania, USA. ### ![Graphic][8] Patients: 265 patients (303 hips) (mean age 58 y, 52% men) who received uncemented primary THA through an anterolateral approach. Exclusion criteria included previous surgery on the ipsilateral hip, hyperflexibility syndromes, and neuromuscular compromise (eg, Alzheimer’s or Parkinson’s disease). ### ![Graphic][9] Intervention: PFR (n = 152) or no PFR (n = 151). All patients were expected to limit the range of motion of the hip for the first 6 weeks to <90° of flexion and 45° of external and internal rotation, and to avoid … [1]: {openurl}?query=rft.jtitle%253DThe%2BJournal%2Bof%2BBone%2Band%2BJoint%2BSurgery%26rft.stitle%253DJBJS%26rft.aulast%253DJung%26rft.auinit1%253DY.-B.%26rft.volume%253D87%26rft.issue%253D1_suppl_2%26rft.spage%253D247%26rft.epage%253D263%26rft.atitle%253DReconstruction%2Bof%2Bthe%2BPosterior%2BCruciate%2BLigament%2Bwith%2Ba%2BMid-Third%2BPatellar%2BTendon%2BGraft%2Bwith%2BUse%2Bof%2Ba%2BModified%2BTibial%2BInlay%2BMethod%26rft_id%253Dinfo%253Apmid%252F16140798%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/external-ref?access_num=16140798&link_type=MED&atom=%2Febnurs%2F8%2F4%2F115.atom [3]: /embed/inline-graphic-1.gif [4]: /embed/inline-graphic-2.gif [5]: /embed/inline-graphic-3.gif [6]: /embed/inline-graphic-4.gif [7]: /embed/inline-graphic-5.gif [8]: /embed/inline-graphic-6.gif [9]: /embed/inline-graphic-7.gif

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.
