In this study, we aimed to investigate the relationship between union time and functional scores in patients who underwent reconstruction with free vascularized fibular grafts (FVFG) for large segment bony defects resulting from resection of bone tumors. <b>Methods:</b> This retrospective study aims to evaluate the clinical outcomes of using free vascularized fibula grafts for the reconstruction of segmental defects following tumor resection at our institution between 2005 and 2021. The tools used for clinical assessment included the Visual Analog Scale (VAS), the Musculoskeletal Tumor Society (MSTS) score, and the Short Form-36 (SF-36) quality of life scale. The relationship between functional outcomes and union time was analyzed retrospectively. The patients were divided into two groups based on union time: those with a union time shorter than 6 months and those with a union time longer than 6 months. The relationship between union time and functional outcomes was analyzed. Additionally, the effects of gender, affected extremity, tumor location, defect size, preoperative and postoperative chemotherapy (CT) and/or radiotherapy (RT) status, presence of distant metastasis, postoperative complications, and hospital stay duration on union time were investigated. <b>Results:</b> A total of 45 patients were included in the study, comprising 20 females and 25 males, with a mean age of 31.3 years (min: 10, max: 74). Seventeen patients had tumors of the upper extremity, while 28 had tumors of the lower extremity. All patients underwent reconstruction of segmental bone defects using free vascularized fibula grafting (FVFG). Preoperative SF-36 quality of life scores were significantly lower when compared to postoperative scores. The patients were categorized into two groups based on union time: those who achieved union within 6 months and those with a union time exceeding 6 months. The analysis demonstrated that patients with upper extremity tumors had a faster union time, while those who experienced postoperative complications had a prolonged union time. Furthermore, extended hospital stays, the presence of preoperative and/or postoperative chemotherapy (CT) and/or radiotherapy (RT), and distant metastasis were associated with lower MSTS scores. However, this decrease in MSTS scores was not statistically significant. <b>Conclusions:</b> Free vascularized fibula grafts are effective biological reconstruction methods that accelerate bone union. The average union time is 6 months, extending up to 9-12 months in some cases.

Body roundness index (BRI), a novel obesity assessment index, accurately reflects body fat distribution, but its relationship with OP risk in T2DM patients has not been clarified. The aim of this study was to investigate the nonlinear relationship between BRI and OP risk in patients with T2DM. <b>Methods:</b> In this study, based on data from the 2005-2018 National Health and Nutrition Examination Survey, we conducted a cross-sectional study involving 3,178 people with T2DM. Femoral bone mineral density was measured using dual-energy X-ray absorptiometry. Generalized additive model was used to assess the non-linear relationship between BRI and OP risk. Multiple logistic regression analyses were used to assess the relationship between BRI and OP risk, adjusted for various covariates. Subgroup analyses for age, sex, and ethnicity were also performed to assess the consistency and robustness of the results. <b>Results:</b> Generalized additive model analyses demonstrated an L-shaped relationship between BRI and OP risk, and logistic regression analyses indicated that BRI exhibited a negative association with OP risk. The risk of OP exhibited a significant decrease with increasing BRI and appeared to saturate at a BRI of approximately 5.08.

They were divided into two groups: 20 treated with the Lasso-loop technique and 20 with the Jaw-designed suture passer. Functional outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) scale, Karlsson Ankle Functional Score (KAFS), Tegner activity scale (TAS), and Visual Analog Scale (VAS) for pain. Intraoperative ligament stitch time was also recorded for both groups.ResultsBoth groups showed significant improvement in AOFAS, KAFS, TAS, and VAS scores from preoperative to final follow-up (<i>p</i> < .001).

The patients in the series were divided into two groups according to the surgery they underwent: patients who underwent isolated ADLC in group A and ADLC with autografting in group B. The wrist range of motion, patient satisfaction, Visual Analogue Scale (VAS) and the Mayo Wrist Score (MWS) were used for clinical and functional results.ResultsGroup A consisted of 12 (7 females - 5 males), Group B consisted of 14 (9 females - 5 males). The mean age was 33,1 years in Group A (range 22-49), and 32,3 years in Group B (range 21-47). The VAS, Mayo Wrist Score, wrist range of motion, and the level of patient satisfaction were similar in the two groups.
