For diagnostic approach, the highest significance in area under the curve (AUC) values was obtained for NLR (AUC=0.763). The AUC for PLR and LMR was statistically significant, while the statistical power was weak compared to NLR (AUC=0.681 and 0.603). The NLR, PLR, and LMR were found to be predictors of mortality. The cut-off value was found to be 3.28 for NLR, 128 for PLR, and 4.22 for LMR. The prognostic value of NLR for mortality was higher than (AUC=0.749) PLR (AUC=0.688) and LMR (AUC=0.609). The NLR, PLR, and LMR were associated with overall survival (OS). There was a significant difference in the median OS time among the NLR, PLR, and LMR values (log-rank test order p<0.001, p=0.001, and p=0.004, respectively).

Based on our study results, pre-treatment NLR, PLR and MLR have diagnostic and prognostic values in osteosarcoma.

The aim of this study was to evaluate the clinical and radiographic outcomes and complications of dual magnetically controlled growing rods (MCGRs) in the treatment of early-onset scoliosis (EOS) and to investigate the results of patients with definitive spinal fusion following MCGR.

A total of 15 patients (7 males, 8 females; mean age 8.7±1.7 years; range, 6 to 10 years) with EOS who underwent dual MCGR and were prospectively followed between February 2013 and March 2019 were included in this retrospective study. The Cobb angle, thoracic kyphosis, and the length of the spine between T1-T12 and T1-S1 were measured on preoperative, postoperative, and follow-up radiographs. The 24-Item Early-Onset Scoliosis Questionnaire (EOSQ-24) was used to assess the functional outcomes before and after the operation. All complications during the treatment were recorded.

The mean follow-up was 27.8±10.4 (range, 12 to 60) months. The mean curve correction immediately after the index surgery and latest follow-up was 47.6rrected successfully with definitive surgery.
Dual MCGR technique is an effective, reliable, and robust treatment alternative for primary EOS. However, surgeons should be aware of the relatively high rate of complications. In addition, residual deformity can be corrected successfully with definitive surgery.
In this study, we describe a novel hemiepiphysiodesis technique to prevent implant-related perichondrial ring injury in a rabbit model.

Proximal tibial epiphyseal plates of a total of 16 white New Zealand rabbits were used for this animal model. The subjects were divided into three equal groups as follows Group 1 (Kirschner wire [K-wire]/cerclage), Group 2 (8-plate) right-hind legs, Group 3 (Control) left hind legs. Using anteroposterior radiography, the medial slope angle (MSA), articular line-diaphyseal angle (ALDA), and the angle between screws of 8-plate in lateral X-ray tibial slope angle (TSA) were measured. The radiographs were taken early postoperative (Day 1) and on sacrification day (Week 8). The histological evaluation of the perichondrial ring was made on a 7-mm axial section that stained with Safranin O/fast green at X10 magnification.

In both K-wire and 8-plate groups, the early postoperative ALDA and TSA were greater than the sacrification ALDA and TSA (p=0.028 and p<0.001, respectively). The early postoperative MSA was lower than the sacrification MSA in groups, (p<0.001). The MSA in the control group was lower than the K-wire and 8-plate groups (p<0.001 and p=0.009; respectively). The perichondrial ring thickness of the K-wire group was greater than the 8-plate group in histological evaluation (p<0.001).

Both of the K-wire and 8-plate groups showed similar angulation effects in the proximal tibia, although histologically less damage to the perichondrial ring was observed in the K-wire group, compared to the 8-plate group.

The aim of this study was to evaluate correlation of post-reduction magnetic resonance imaging (MRI)-based parameters with residual acetabular dysplasia in developmental dysplasia of the hip (DDH) patients who underwent open reduction.

A total of 62 hips of 54 children (5 males, 57 females; mean age 8.5±3.5 months; range, 0 to 24 months) with a diagnosis of DDH who underwent open reduction between January 2012 and January 2017 were retrospectively analyzed. The acetabular head index (AHI), head coverage index (HCI), sphericity, bony acetabular index (BAI), cartilage acetabular index (CAI), anterior acetabular index (AAI), posterior acetabular index (PAI), abduction angle (AA), and acetabular medial wall thickness were measured by MRI. The correlation between MRI measurements and residual acetabular dysplasia was evaluated.

The mean follow-up was 23.7±10.1 (range, 12 to 56) months. The mean age at the final examination was 47.6±10.4 months. The age at the time of operation (r=0.250, p=0.049), medial wall thickness (r=0.304, p=0.016), AAI (r=0.729, p<0.001), PAI (r=0.590, p<0.001), and early postoperative AI (r=0.900, p<0.001) at the third postoperative month were positively correlated with the last follow-up AI. The AHI (r=-0.512, p<0.001), sphericity (r=-0,661, p<0.001), and HCI (r=-0.554, p< 0.001) were negatively correlated with the last follow-up AI.

The aim of this study is to investigate whether rigid fixation after triple pelvic osteotomy (TPO) utilizing a 3.5-mm locking plate and screws without hip spica cast can provide enough stability and prevent correction loss in pediatric patients with developmental dysplasia of the hip (DDH) and Legg-Calvé-Perthes disease (LCPD).

A total of 21 hips of 21 pediatric patients (9 males, 12 females; mean age 9.3±2.0 years; range, 6 to 14 years) who underwent rigid fixation with locking plate/screws after TPO for DDH and LCPD between June 2015 and October 2018 were retrospectively analyzed. Preoperative, immediate postoperative, and six-month follow-up anteroposterior radiographs were compared for the Wiberg's center-edge angle (CE), Sharp angle, acetabular coverage of the femoral head (ACFH), and center-head distance discrepancy (CHDD). The patient demographics, surgery time, perioperative complications were evaluated.

Underlying diagnosis were DDH in 14 patients and LCPD in seven patients. In patients with DDoss of correction, until bony healing at the osteotomy sites.
Our study results suggest that rigid fixation construct with a 3.5-mm locking plate and screws without hip spica cast can provide adequate stability to allow early mobilization following TPO in children without any loss of correction, until bony healing at the osteotomy sites.
This study aims to evaluate the clinical and functional results of patients treated with InSafeLOCK® humeral nail and iliac crest autograft for humeral nonunion.

A total of 15 patients (11 males, 4 females; mean age 52.1±15.3 years; range, 31 to 78 years) who were followed conservatively for humeral fractures and operated with the InSafeLOCK® humeral nail and iliac bone graft in our center between June 2018 and January 2020 were retrospectively analyzed. Data including demographic and clinical characteristics of the patients, operative data, and pre- and postoperative Visual Analog Scale (VAS), Disabilities of the Arm, Shoulder, and Hand (DASH), and Constant-Murley Scores (CMS) were recorded.

The mean time from injury to nonunion treatment was 10.9±1.6 months. Five patients had atrophic, eight patients had oligotrophic, and two patients had hypertrophic nonunion. Preoperatively, the mean DASH was 37.7±9.1, the mean CMS was 69.7±6.3, and the mean VAS was 3.8±0.7. In all patients, union was achieved. The mean operation time was 59.0±16.2 min. The mean postoperative DASH score was 16.1±8.7, CMS 87.4±3.4, and VAS score 0.8±0.7. Regarding the shoulder joint, the mean abduction was 164.7±11.3 degrees, the mean internal rotation was 82.0±6.8 degrees, the mean external rotation was 81.3±8.3 degrees, and the mean flexion was 162.0±12.1 degrees. During follow-up, complications such as vascular-nerve injury, reflex sympathetic dystrophy, screw migration or loosening, implant failure, and loss of reduction did not occur in any of our patients.

This study aims to compare the outcomes of patients undergoing a single anterior portal or a standard two-portal arthroscopic procedure for Bankart repair.

Between January 2015 and March 2018, a total of 71 consecutive patients (53 males and 18 females; mean age 33.3±10.3 years; range, 17 to 56 years) who underwent arthroscopic Bankart repair with a minimum two-year follow-up period were included. The patients were divided into two groups according to the arthroscopic technique used single anterior portal group (Group 1, n=32) and standard two-portal group (Group 2, n=39). Demographic and surgical characteristics of the patients were recorded. Pre- and postoperative clinical and functional outcomes were evaluated using the external rotation degree, as well as Visual Analog Scale (VAS), American Shoulder and Elbow Surgeons (ASES), University of California at Los Angeles (UCLA) Shoulder Rating Scale, Constant-Murley Score (CMS), Oxford Shoulder Instability Score (OSIS), and Rowe scores. The clinical and funs activity level. The mean time to return to sports was 7.2±1.7 months.

Good-to-excellent clinical and functional outcomes can be obtained after arthroscopic Bankart repair, regardless of the use of a single or two anterior working portals. However, the single-portal technique is associated with reduced the operative time, compared to two-portal technique.
