OBJECTIVE: To analyze patients, injury patterns, and treatment of femoral neck fractures (FNFs) in young patients with FNFs associated with shaft fractures (assocFNFs) to improve clinical outcomes. The secondary goal was to compare this injury pattern to that of young patients with isolated FNFs (isolFNFs).
METHODS:
METHODS: Retrospective multicenter cohort series.
METHODS: Twenty-six North American level-1 trauma centers.
UNASSIGNED: Skeletally mature patients, <50 years old, treated with operative fixation of an FNF with or without an associated femoral shaft fracture.
UNASSIGNED: The main outcome measurement was treatment failure defined as nonunion, malunion, avascular necrosis, or subsequent major revision surgery. Odds ratios for these modes of treatment were also calculated.
RESULTS: Eighty assocFNFs and 412 isolFNFs evaluated in this study were different in terms of patients, injury patterns, and treatment strategy. Patients with assocFNFs were younger (33.3 ± 8.6 vs. 37.5 ± 8.7 years old, P < 0.001), greater in mean body mass index [BMI] (29.7 vs. 26.6, P < 0.001), and more frequently displaced (95% vs. 73%, P < 0.001), \"vertically oriented\" Pauwels type 3, P < 0.001 (84% vs. 43%) than for isolFNFs, with all P values < 0.001. AssocFNFs were more commonly repaired with an open reduction (74% vs. 46%, P < 0.001) and fixed-angle implants (59% vs. 39%) (P < 0.001). Importantly, treatment failures were less common for assocFNFs compared with isolFNFs (20% vs. 49%, P < 0.001) with lower rates of failed fixation/nonunion and malunion (P < 0.001 and P = 0.002, respectively). Odds of treatment failure [odds ratio (OR) = 0.270, 95% confidence interval (CI), 0.15-0.48, P < 0.001], nonunion (OR = 0.240, 95% CI, 0.10-0.57, P < 0.001), and malunion (OR = 0.920, 95% CI, 0.01-0.68, P = 0.002) were also lower for assocFNFs. Excellent or good reduction was achieved in 84.2% of assocFNFs reductions and 77.1% in isolFNFs (P = 0.052). AssocFNFs treated with fixed-angle devices performed very well, with only 13.0% failing treatment compared with 51.9% in isolFNFs treated with fixed-angle constructs (P = <0.001) and 33.3% in assocFNFs treated with multiple cannulated screws (P = 0.034). This study also identified the so-called \"shelf sign,\" a transverse ≥6-mm medial-caudal segment of the neck fracture (forming an acute angle with the vertical fracture line) in 54% of assocFNFs and only 9% of isolFNFs (P < 0.001). AssocFNFs with a shelf sign failed in only 5 of 41 (12%) cases.
CONCLUSIONS: AssocFNFs in young patients are characterized by different patient factors, injury patterns, and treatments, than for isolFNFs, and have a relatively better prognosis despite the need for confounding treatment for the associated femoral shaft injury. Treatment failures among assocFNFs repaired with a fixed-angle device occurred at a lower rate compared with isolFNFs treated with any construct type and assocFNFs treated with multiple cannulated screws. The radiographic \"shelf sign\" was found as a positive prognostic sign in more than half of assocFNFs and predicted a high rate of successful treatment.

UNASSIGNED: To compare the effectiveness of intramedullary nailing fixation via suprapatellar approach and medial parapatellar approach in semi-extended position in the treatment of multiple tibial fractures.
UNASSIGNED: The clinical data of 43 patients with multiple tibial fractures treated with intramedullary nailing fixation between July 2018 and December 2022 were retrospectively analyzed, including 23 patients treated with suprapatellar approach in semi-extended position (group A) and 20 patients with medial parapatellar approach in semi-extended position (group B). There was no significant difference in gender, age, cause of injury, time from injury to operation, AO/Orthopaedic Trauma Association (AO/OTA) classification, preoperative visual analogue scale (VAS) score, and range of motion (ROM) of the knee joint between the two groups ( P>0.05). The operation time, intraoperative blood loss, incision length, intraoperative fluoroscopy frequency, and fracture healing time were recorded and compared. The VAS score and ROM of the knee joint were analyzed at 4, 8, and 12 weeks after operation, and the incidence of postoperative complications was observed; knee function was evaluated by Lysholm score at last follow-up.
UNASSIGNED: The operations were successfully completed in both groups, and there was no complication such as nerve and blood vessel injury during operation, and all incisions healed by first intention. There was no significant difference in operation time, intraoperative blood loss, and intraoperative fluoroscopy frequency between the two groups ( P>0.05), but the incision length in group B was significantly longer than that in group A ( P<0.05). Patients in both groups were followed up 12-30 months, with an average of 21.1 months. The VAS score decreased and ROM increased gradually in both groups with time after operation, showing significant differences between different time points ( P<0.05). The VAS score of group B was significantly lower than that of group A at 4 and 8 weeks after operation ( P<0.05); there was no significant difference in VAS score and ROM between the two groups at other time points ( P>0.05). There was no significant difference in fracture healing time between the two groups ( P>0.05). During the follow-up, there was no complication such as internal fixator loosening, breakage, and loss of fracture reduction. At last follow-up, the Lysholm score in group B was significantly better than that in group A ( P<0.05).
UNASSIGNED: Both the suprapatellar approach and the medial parapatellar approach in semi-extended position can achieve satisfactory results in the treatment of multiple tibial fractures. The medial parapatellar approach has lower symptoms of early knee pain and better long-term function.
UNASSIGNED: 比较膝关节半伸直位髌上入路与髌旁内侧入路髓内钉固定治疗胫骨多段骨折的临床疗效。.
UNASSIGNED: 回顾分析2018年7月—2022年12月收治且符合选择标准的43例采用髓内钉固定治疗的胫骨多段骨折患者临床资料，其中23例采用膝关节半伸直位髌上入路（A组），20例采用膝关节半伸直位髌旁内侧入路（B组）。两组患者性别、年龄、致伤原因、受伤至手术时间、骨折国际内固定研究协会/美国骨创伤协会（AO/OTA）分型及术前疼痛视觉模拟评分（VAS）、膝关节活动度（range of motion，ROM）等基线资料比较差异均无统计学意义（ P>0.05）。记录并比较两组患者手术时间、术中失血量、切口长度、术中透视次数及骨折愈合时间，统计两组术后4、8、12周膝关节VAS评分及ROM，观察术后并发症发生情况；末次随访时采用Lysholm 评分评价膝关节功能。.
UNASSIGNED: 两组患者均顺利完成手术，术中无神经、血管损伤等并发症发生，术后所有切口均Ⅰ期愈合。两组手术时间、术中失血量、术中透视次数比较差异均无统计学意义（ P>0.05）；但B组手术切口长于A组，差异有统计学意义（ P<0.05）。两组患者均获随访，随访时间12～30个月，平均21.1个月。术后随时间延长，两组膝关节VAS评分均逐渐降低，ROM逐渐增加，各时间点间差异均有统计学意义（ P<0.05）；术后4、8周B组VAS评分低于A组，差异有统计学意义（ P<0.05），其余时间点两组间比较膝关节VAS评分及ROM差异均无统计学意义（ P>0.05）。两组骨折均愈合，愈合时间比较差异无统计学意义（ P>0.05）。随访期间无内固定物松动、断裂及骨折复位丢失等并发症发生。末次随访时，B组膝关节Lysholm评分显著优于A组，差异有统计学意义（ P<0.05）。.
UNASSIGNED: 膝关节半伸直位髌上入路与髌旁内侧入路髓内钉固定治疗胫骨多段骨折均可获得满意疗效，髌旁内侧入路术后早期膝关节疼痛症状更轻，远期膝关节功能更优。.

UNASSIGNED: Bone marrow embolism is known to occur after fractures of long bones such as the femur and pelvis. We report a case of multiple fractures in a 32-year-old female patient, demonstrating bone marrow elements in the peripheral blood as early as 2 hours after trauma. This is the first case being reported with an ante-mortem demonstration of circulating marrow emboli in the peripheral blood, while the previously reported cases have demonstrated the emboli in post-mortem examination. A careful correlation of the clinical history of trauma, hematology auto-analyzer results, and the presence of bone marrow particles and fat globules in peripheral blood helped in arriving at the diagnosis of fat embolism in our case irrefutably.

Non-traumatic fractures due to seizures are an overlooked diagnostic group. It is well known that patients with generalized tonic-clonic seizures have an increased trauma risk. However, the cause of fracture is rarely due to the violent forces of muscle contractions. Usually, the primary patient examination focuses on the aetiology of the seizure, which sometimes delays the diagnosis of fractures. This is a case report of a 19-year-old woman who sustained three compression fractures of the thoracic spine due to a generalized tonic-clonic seizure, and a discussion of the diagnostic challenges in such a rare case.

It\'s reported that 10% of the inpatients by traumas have fractured ribs. It\'s easy to judge if it\'s the case of flail chest, or respiratory failure due to airway injury or pulmonary contusion. There is no guideline for treatments of a patient who has multiple ribs fractures without respiratory failure. We did the surgical stabilization of rib fractures for 10 cases from 2020 to October 2023. As a result, we find out useful surgical indication for treatment of rib fractures.

In case that met several indication criteria with 4 or more rib fractures, we performed surgical stabilization of multiple fractured ribs using a plate and screw system( Super FIXORB MX) that was made of uncalcined hydroxyapatite (u-HA)/poly-L-lactic acid (PLLA) composite material with excellent bioactivity and absorbability. We report our clinical experience of 7 cases in which this device was used. Although there is still room for further consideration of the technique and the strength of the device itself, computed tomography( CT) images taken 9 months after surgery showed that the fixative device was almost assimilated with the bone at the fracture repair site in cases where fixation was successful.

BACKGROUND: Rib fixation for traumatic rib fractures is advocated to decrease morbidity and mortality in select patient populations. We intended to investigate the effect of combination osseous thoracic injuries on mortality with the hypothesis that combination injuries will worsen overall mortality and that SSRF will improve outcomes in combination injuries and in high-risk patients.
METHODS: Patients with rib fractures were identified from the Trauma Quality Improvement Project registry from 2019. Patients were then divided into rib fracture(s) alone or in combination with sternal, thoracic vertebra, or scapula fracture. Patients were also categorized into those with COPD and smokers. Patients with AIS >3 outside of thorax were excluded. Patients were subcategorized into those who had rib fixation verse nonoperative management for all subgroups. Analysis was performed to evaluate the efficacy of rib fixation.
RESULTS: A total of 111,066 patients were included for analysis. The overall mortality was 1.4%. Patients with COPD had over double the mortality risk, with an overall mortality of 3.4%. Combination injuries did not appear to increase mortality. SSRF did not decrease mortality; however, the number of patients in this group was too small to complete statistical analysis. The overall complication rate was 0.43%. There was a trend towards an increase in extrapulmonary complications in the group that underwent surgical fixation.
CONCLUSIONS: Mortality from rib fractures with concomitant osseous thoracic fracture appears to be low. However, mortality is increased in patients with COPD regardless of rib fracture pattern. The number of patients who underwent SSRF was too small to make a statistical comparison.

UNASSIGNED: Ten percent of all injured patients and 55% of patients with blunt chest trauma experience rib fractures. The incidence of death due to rib fractures is related to the number of fractured ribs, severity of fractured ribs, and patient age and comorbid conditions. Death due to rib fracture is mostly caused by pneumonia because of inability to expectorate and take deep breaths. Over the last 25 to 30 years, there has been renewed interest in surgical stabilization of rib fractures (SSRF), known colloquially as \"rib plating.\" This review will present what you need to know in regard to triage decisions on whether to admit a patient to the hospital, the location to which they should be admitted, criteria and evidentiary support for SSRF, timing to SSRF, and operative technique. The review also addresses the cost-effectiveness of this operation and stresses nonoperative treatment modalities that should be implemented prior to operation.

Maxillofacial fractures in the pediatric population are generally managed by conservative approaches such as soft diet and medication or semi-invasive procedures namely inter-maxillary fixation or circum-mandibular wiring. These approaches are preferred over any invasive treatment to minimize injury to the growing skeleton and tooth germs. Displaced fractures that cause functional problems such as restricted mouth opening, malocclusion or impaired breathing, mandate open reduction and internal fixation. However, surgical management is associated with morbidity related to general anesthesia, risk of injury to vital structures, and potential, skeletal or dental growth disturbances. This case report describes a non-invasive method of managing displaced, multiple fractures of the mandible in a pediatric patient, with the use of low intensity pulsed ultrasound to achieve favorable clinical outcomes and nil complications. Neither immobilization of the mandible with inter-maxillary fixation nor open reduction and internal fixation was used. Low intensity pulsed ultrasound therapy is painless and patient-friendly.

BACKGROUND: In daily practice the diagnostic process for osteoporosis in elderly patients should also include physical assessment. The aim of the study was to verify the hypothesis that height loss (HL) predicts fracture incidence.
METHODS: The study was performed in an epidemiological sample of postmenopausal women recruited in the RAC-OST-POL study. At baseline, data were collected in 978 postmenopausal women at a mean age of 66.48±7.6 years, and at 10-year follow-up 640 patients remained, with a mean age of 75.04 ± 6.95 years. Current height and HL were established in regard to maximal life height. Data on fracture incidence were gathered throughout the period of observation.
RESULTS: During the follow-up period 190 osteoporotic fractures were noted. Ninety-one women had one fracture, and in 38 women, multiple fractures occurred. In the fractured and unfractured subgroups, HL was 5.45 ± 3.28 and 4.8 ± 3.56 cm, respectively, and differed significantly (p < 0.05). HL in subjects without fracture did not differ from those with one fracture (HL 4.8 ± 3.56 vs. 4.8 ± 2.66 cm, respectively). For patients with more than one fracture HL was 7.03 ± 4.06 cm and was significantly higher than in subjects with one or without any fracture (p < 0.01). Based on receiver operating characteristic (ROC) analysis, HL of 6 cm was identified as the cut-off point for high risk of multiple fractures.
CONCLUSIONS: HL of at least 6 cm is the predictor of multiple fractures in a prospective observation of a representative epidemiological female sample. Therefore, the measurement of HL should always be included in patients\' assessments.
