Functional outcome and multidimensional evaluation of patients with mutars® reconstructions post lower limb tumor resection and rehabilitation: Preliminary results
Bibliographic record
Abstract
Modular prostheses are commonly used to reconstruct defects of the distal femur and proximal tibia after bone tumor resection. Improving patient’s autonomy and giving them a better quality of life are the main goals. Post-surgical rehabilitation is very relevant after surgery. The aim of this paper is to study the short and mean time functional outcomes in patients treated with Mutars® reconstructions after proximal and distal lower limb tumor resection with a multidimensional analysis and a standardized stabilometric examination. Twenty-one patients (7 male and 14 women, mean age and standard deviation: 61.76±14.68) affected by primitive bone tumor (28.6%) or metastatic bone tumor (71.4%), treated with MUTARS® reconstructions after proximal (71%), distal(23.8%) and both (4.8%) lower limb tumor resections, accepted to take part to the study. They were evaluated after one week (T0), one month (T1), three months (T2), six months (T3) and one year (T4) after surgery with standardized clinic evaluation and with multidimensional validated scales. Visual Analogic Scale (VAS during active movement), Short Physical Performance Battery (SPPB), Eastern Cooperative Oncology Group (ECOG), Karnofsky Performance Status (KPS), MusculoSkeletal Tumor Society rating (MSTS), Toronto Extremity Salvage Score scale (TESS). Patients underwent to an instrumental standardized stabilometric test after one month from surgery and in following evaluations to measure standing balance. Patients underwent to a rehabilitation program during three months after surgery. There was a significant improvement of hip flexion range of movement (p level: 0.008), and gait modalities (without aids) after three months from surgery (p level 0.02). There was a significant reduction in VAS after one month of surgery (p level 0.00). It was observed an increase of the SPPB value at T3 (p level 0.01), of MSTS and TESS at T2. Balance stabilometric evaluation did not showed significant increase at each timing also if Romberg perimeter decrease progressively. These preliminary results showed that, oncological patients, affected by bone tumors or metastasis, surgical treated with MUTARS® implant and admitted to the rehabilitation programs, can improve their gait modalities and functional daily life outcomes, until three months from surgery. A large sample will allow, necessary to define standardized rehabilitation protocols after oncological orthopedic surgery, in order to introduce guidelines that can be applied routinely.

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.
