The clinical effects of artificial dermis in the treatment of skin and soft tissue defects accompanied by bone or tendon exposure
Bibliographic record
Abstract
Objective The clinical effects of artificial dermis in treating skin and soft tissue defects accompanied by bone or tendon exposure were assessed. Approach A retrospective analysis was conducted on the clinical data of 45 cases of skin and soft tissue defects accompanied by bone or tendon exposure admitted to the trauma surgery department of Fujian Provincial Hospital between February 2018 and August 2020. They were divided into the artificial dermis and control groups. The wound was assessed using the Vancouver Scar Scale (mVSS), and the postoperative visual analogue scale (VAS) scores were recorded at 3, 6, 9, and 12 months after surgery. At the 12-month after surgery, skin sensation recovery was evaluated using the criteria of the British Medical Research Council (BMRC). Results The cases included 26 males and 19 females, aged 50 to 85 years. All patients were followed up for an average of 13.8 months (range: 12–18 months). Compared with controls, the wound healing time of the observation group was longer (35.8 ± 10.6 vs. 28.5 ± 4.8, P = 0.007), without significant differences for the number of operations and length of hospitalization. The mVSS scores were not different between groups (P group = 0.294), but the scores decreased with time (P time < 0.001), and the group×time interaction was significant (P interaction < 0.001). Similarly, the VAS scores were not different between groups (P group = 0.667), but the scores decreased with time (P time < 0.001); the group×time interaction was not significant (P interaction = 0.274). At the 12-month mark following the operation, in the artificial dermis group, the MCRR score was S3+ in 23 patients, while it ranged from S0 to S3 in two patients; in the control group, S3+ was observed in 17 patients, and S0-S3 in three ( P = 0.815). Conclusion Artificial dermis treatment is considered a safe and effective alternative therapy for patients with skin and soft tissue defects accompanied by bone or tendon exposure who cannot tolerate or are unwilling to undergo autologous skin flap transplantation. It offers the advantages of minimal donor site trauma, simplicity in operation, and favorable postoperative functional recovery.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
