Purpose: Prompt vascular access is crucial for resuscitating bleeding trauma casualties in prehospital settings but achieving peripheral intravenous (PIV) access can be challenging during hemorrhagic shock due to peripheral vessel collapse. Early intraosseous (IO) device use is suggested as an alternative. This study examines injury characteristics and factors linked to IO access requirements.

Methods: A registry-based cohort study from the Israel Defense Forces Trauma Registry (2010 - 2023) included trauma casualties receiving PIV or IO access prehospital. Casualties who had at least one documented PIV or IO access attempt were included, while those without vascular access were excluded. Casualties requiring both PIV and IO were classified in the IO group. Univariable logistic regression assessed the factors associated with IO access. Results were reported as odds ratios (OR) with 95% confidence intervals (CI), and significant difference was set at p < 0.05.

Results: Of 3462 casualties (86.3% male, the median age: 22 years), 3287 (94.9%) received PIV access and 175 (5.1%) had IO access attempts. In the IO group, 30.3% received freeze-dried plasma and 23.4% received low titer group O whole blood, significantly higher than that in the PIV group. Prehospital mortality was 35.0% in the IO group. Univariable analysis showed significant associations with IO access for increased PIV attempts (OR = 1.69; 95% CI: 1.34 - 2.13) and signs of profound shock (OR = 11.0; 95% CI: 5.5 - 23.3).

Conclusion: Profound shock signs are strongly linked to the need for IO access in prehospital settings with each successive PIV attempt increasing the likelihood of requiring IO conversion. IO access often accompanies low titer group O whole blood or freeze-dried plasma administration and higher prehospital mortality, indicating its use in emergent resuscitation situations. Early IO consideration is advised for trauma casualties with profound shock.

Purpose: The reconstruction of Allen's type IV fingertip amputation is a clinical challenge. Our team designed bilateral unequal-sized hallux osteo-onychocutaneous free flaps for the long-term reconstruction of Allen's type IV fingertip amputation and conducted a retrospective study with a 5-year follow-up aims to evaluate the effects of this technique.

Methods: A retrospective analysis with a 5-year follow-up including 13 patients with Allen's type IV fingertip amputation who were admitted to our hospital from January 2010 to January 2017 was conducted. The patients were treated with bilateral unequal-sized hallux osteo-onychocutaneous free flaps. The operation time, intraoperative blood loss, and complications were recorded, and the survival rate of the transplanted flaps was calculated. During the 5-year follow-up after operation, the nail growth time was recorded and the finger appearance was observed. At the last follow-up appointment, the length, width, and girth of the reconstructed fingertip and contralateral normal fingertip, range of motion of the reconstructed fingertip and contralateral normal fingertip, Semmes-Weinstein test (for the evaluation of tactile sensation), and two-point discrimination testing results were recorded. SPSS 22.0 software was used for the statistical analysis and the data are presented as mean ± SD.

Results: The mean operation time was (5.62 ± 0.51) h, the mean intraoperative blood loss was (34.15 ± 3.13) mL, and the survival rate of the transplanted flaps was 100%. During the 5-year follow-up, the average nail growth time was (10.14 ± 1.98) months and the average bone union time was (3.78 ± 0.91) months. The length, width, and girth of the reconstructed fingertip were (31.52 ± 3.73) mm, (17.82 ± 1.74) mm, and (59.75 ± 3.04) mm, respectively, which did not differ from those of the contralateral normal fingertip. The range of motion of the reconstructed fingertip was (12.15 ± 2.79) degrees which is different from that of the contralateral normal fingertip. The average tactile sensation evaluated via the Semmes-Weinstein test and the average two-point discrimination test of the reconstructed fingertip were (0.39 ± 0.17) g and (7.46 ± 1.14) mm, respectively, which were not different from those of the contralateral normal fingertip. The average Maryland score of feet in the donor area was 87.66 ± 7.39, which was satisfactory.

Conclusion: Bilateral unequal-sized hallux osteo-onychocutaneous free flaps are an effective method to reconstruct Allen's type IV fingertip amputations with a satisfactory appearance and good sensory function.

Purpose: In surgical procedures commonly employed for the management of scaphoid and distal radial fractures, the incision and dissection of the pronator quadratus muscle play a pivotal role. Nevertheless, comprehensive investigations into the anatomical intricacies of the pronator quadratus muscle have been relatively scarce within the clinical community. In light of this, our study endeavors to make a substantive contribution to the medical literature by conducting a meticulous examination of the morphology and morphometry of this muscle.

Methods: This study is a cross-sectional observational study conducted on 22 cadaveric upper extremities (44 sides) preserved between January 2005 and December 2018 at Istanbul University. The study included specimens with intact dissection areas and no prior surgical intervention. Observations focused on the morphometry of the pronator quadratus muscle and related anatomical structures. Statistical analysis was performed using SPSS v23.0, employing Student's t-test and paired t-test, with significance set at p < 0.05.

Results: Significant differences were found in the morphometric measurements of the pronator quadratus muscle between the right and left upper extremities, particularly in the vertical distance between the proximal and distal attachment points of the pronator quadratus to the radius (p = 0.008). Additionally, significant differences were observed between male and female samples for radius length (p < 0.001), ulna length (p < 0.001), pronator quadratus width (p < 0.001), and the vertical distance between pronator quadratus attachment points on both the radius (p = 0.001) and ulna (p = 0.001). Furthermore, significant correlations were identified between radius length and parameters such as the vertical distance between pronator quadratus attachment points on both the radius (p = 0.002) and pronator quadratus width (p = 0.03), and between ulna length and parameters including the vertical distances on the radius (p = 0.001) and ulna (p = 0.024).

Conclusion: In light of our comprehensive analysis, which encompasses not only the anatomical features of the pronator quadratus muscle but also its vascular supply and the organization of its neurovascular structures, we posit that our study holds significant implications for the field of orthopedic surgery. We anticipate that this research will furnish valuable insights that can inform and enhance orthopedic procedures.

Purpose: This study aims to identify the prevalence and risk factors of military training-related abdominal injuries and help plan and conduct training properly.

Methods: This questionnaire survey study was conducted from October 2021 to May 2022 among military personnel from 6 military units and 8 military medical centers and participants' medical records were consulted to identify the training-related abdominal injuries. All the military personnel who ever participated in military training were included. Those who refused to participate in this study or provided an incomplete questionnaire were excluded. The questionnaire collected demographic information, type of abdominal injury, frequency, training subjects, triggers, treatment, and training disturbance. Chi-square test and t-test were used to compare baseline information. Univariate and multivariate regression analyses were used to explore the risk factors associated with military training-related abdominal injuries.

Results: A total of 3058 participants were involved in this study, among which 1797 (58.8%) had suffered training-related abdominal injuries (the mean age was 24.3 years and the service time was 5.6 years), while 1261 (41.2%) had no training-related abdominal injuries (the mean age was 23.1 years and the service time was 4.3 years). There were 546 injured patients (30.4%) suspended the training and 84 (4.6%) needed to be referred to higher-level hospitals. The most common triggers included inadequate warm-up, fatigue, and intense training. The training subjects with the most abdominal injuries were long-distance running (589, 32.8%). Civil servants had the highest rate of abdominal trauma (17.1%). Age ≥ 25 years, military service ≥ 3 years, poor sleep status, and previous abdominal history were independent risk factors for training-related abdominal injury.

Conclusion: More than half of the military personnel have suffered military training-related abdominal injuries. Inadequate warm-up, fatigue, and high training intensity are the most common inducing factors. Scientific and proper training should be conducted according to the factors causing abdominal injuries.

Purpose: The purpose of this study is to surveil the injuries in wrestling according to the different age categories and wrestling styles throughout the competition season.

Methods: The study was designed as a descriptive study. The study was conducted during the wrestling competition season in 2023 (from January 2023 to July 2023), which includes 5 different age categories: U-15, U-17, U-20, U-23, and seniors, along with the Turkey National Wrestling Championships. The data of injuries was recorded immediately after the acute injury was treated by the medical expert during the competitions and evaluated according to the parameters that were obtained. In the statistical analysis, the frequency and percentage values were presented as descriptive statistics and the Chi-square test was used.

Results: The study incorporated a total of 6214 wrestlers and a total of 7151 wrestling bouts were performed during these competitions. The analyses indicated that the rate of injury incidence was 42.65‰ in all wrestling styles. When taking account of the injured body parts in all wrestlers' exposures, the occurrence of injuries to the head-face, neck, trunk, upper extremity, and lower extremity, rates of 17.6‰, 1.3‰, 3.6‰, 13.5‰, and 6.6‰, respectively, were observed. According to the pre-diagnosis based on freestyle, Greco-Roman, and female wrestling styles, injuries with bleeding (39.6%, 46.3%, and 14.6%, respectively) and muscle strain (37.9%, 28.7 %, and 52.6%, respectively) most often occurred.

Conclusion: The study findings indicate that most cases of injury appeared to occur in bleeding and muscle strain in all wrestling styles. We suggest that medical experts should set up their health equipment with consideration to the injuries that occur most frequently.

Purpose: Percutaneous ilio-sacral screw (ISS) insertion using conventional C-arm fluoroscopy has been a widely employed technique for pelvic posterior ring fixation, particularly in developing regions. However, this approach presents technical challenges, leading to a high malposition rate. We introduced a new method for ISS insertion without additional equipment or software and suggested whether it could reduce the malposition rate and operating time.

Methods: This is a retrospective cohort study. The study included all patients who underwent percutaneous ISS fixation between January 2020 and December 2022. Patients treated with open reduction or other types of implants were excluded. The patients were divided into 2 groups based on the screw insertion method: Group A utilized the traditional dual-plane adjustment method, while Group B received the newly introduced method. In all cases, conventional C-arm fluoroscopy was the sole guidance during the surgical procedure. Malposition rate, radiation exposure, and operating time were compared between groups. Post-operative CT scans were used to assess screw accuracy using the Smith grading method. The Student's t-test or the Mann-Whitney U test was chosen for comparing the quantitative variables based on the normality test results. The Chi-squared test was utilized for comparing qualitative variables.

Results: A total of 72 patients with pelvic posterior ring disruption treated with percutaneous ISS under conventional fluoroscopy guidance were included in this study. Among them, 32 patients were in Group A and 40 patients were in Group B. In Group B, the average operation duration per screw was 33 min with 29 fluoroscopy applications, which was significantly lower than that in Group A (44 min, p < 0.001, 38 times, p < 0.001, respectively). Furthermore, the post-operative CT scan revealed that only 10.7% (6/56) of screws in Group B were inappropriately positioned according to the Smith criteria.

Conclusion: The novel method introduced in this study demonstrated a reduction in both malposition rates and operating time compared to the traditional dual-plane adjustment method. Precise pre-operative CT planning in conjunction with conventional fluoroscopy could establish this method as a widely applicable technique for percutaneous ISS fixation.

Purpose: Autologous osteoperiosteal transplantation (AOPT) is one of the most feasible and effective techniques for cystic osteochondral lesions of the talus (OLT). However, few reports have been reported about the process of graft-host bone healing and bone articular surface reconstruction, which help us to further understand the actual situation of bone healing and modify surgical methods.

Methods: We retrospectively evaluated 33 osteochondral lesions in 30 patients undertaking AOPT for OLT with subchondral cysts from December 2016 to October 2021. According to CT observation, we used 4 variables to describe the bony articular repair, including the integration of the articular surface, the height of the bone filling, the status of bone union, and the appearance of bone resorption or cystic change. We also analyzed the demographic data and clinical function. Descriptive statistics were used for demographic and clinical variables. Normally distributed data were presented as mean ± SD, and non-normally distributed data were presented as median (Q₁, Q₃). Associations between these variables and the primary clinical outcomes were examined using t-test or one-way ANOVA test for continuous variables.

Results: The patients' mean age was (41.7 ± 14.0) years old and the mean follow-up time was (29.6 ± 17.8) months. The chondral lesion size was (14.3 ± 4.1) mm. The cyst depth was (10.9 ± 3.7) mm. Significant improvements were observed in functional outcomes (according to the numeric rating scale for pain when walking and the American orthopedic foot and ankle society score) between the preoperative and latest follow-up evaluations, from 4.2 ± 2.1 to 2.2 ± 2.0 (p < 0.001), and from 66.8 ± 12.9 to 83.2 ± 10.4, respectively (p < 0.001). The overall satisfaction reached 8.3 of 10 points. All patients returned to sports and their median daily steps reached 8000 steps with 27 (81.8%) patients walking over 6000 steps daily. According to CT observation, "discontinuous bony articular surface and gap > 1 mm" was found in 27 grafts (81.8%), and "below the level of the adjacent articular surface, ≤ 1 mm" in a third of the grafts. Abnormal height of bone filling affected numeric rating scale score (p = 0.049) and American Orthopedic Foot and Ankle Society score (p = 0.027). Of note, bone resorption or cystic changes appeared in up to 13 autografts (39.4%).

Conclusions: AOPT is an effective and acceptable technique for cystic OLT. Bone reconstruction is essential for large cystic OLT. How to get better bony articular reconstruction and avoid cyst recurrence should still be paid more attention.

Spinal intradural (subdural and subarachnoid) hematoma following percutaneous kyphoplasty is an extremely rare complication. In this report, we described a case of 2 episodes of subarachnoid hemorrhage with delayed paralysis after kyphoplasty. A 73-year-old man underwent percutaneous kyphoplasty in our hospital an osteoporotic vertebral fracture at the T12 level. On the 55 h after kyphoplasty for T12 osteoporotic vertebral fracture, he developed paralysis of the lower limbs. An emergency posterior decompression from T8 to L2 was performed. And the subarachnoid hematomas were removed. Postoperatively, the neurological symptoms improved rapidly. However, 2 weeks after the operation, the patient experienced a setback with severe neurological decline (paraplegia with sensory and autonomic dysfunction). An emergency posterior decompression from T5 to L2 was performed. The subarachnoid hematomas were removed. This case reflects the cause and progression of spinal subdural hematoma. Previous literature has debated the best treatment approach for spinal subarachnoid hemorrhage, but the prognosis of patients is heavily dependent on precise symptom evaluation and localization.
