OBJECTIVETo analyze the characteristics of cases of maxillary complex injury, to sum up experiences and lessons in the clinical first aid process, to evaluate different treatment effects of maxillary complex fracture and investigate the reasons for the failure of the treatment process.

METHODS152 cases with maxillary complex injury were analyzed retrospectively.

RESULTS2 cases (1.32%) died during emergency treatment. The cure rate was 62.67% (94/ 150) in the 150 survival cases. The cure rate of closed fractures were better than open ones and surgical treatments than non-surgical ways (P < 0.05); the cure rate of surgical treatment in stage I was higher than II (P < 0.01).

CONCLUSIONFor patients with complex injuries of maxillary, first aid failure is mainly due to bleeding or asphyxiation. Therapeutic efficacy is influenced by treatment time, surgical approach, type of treatment and so on. The key to success of treatment is dependent on the early firm internal fixation and the functional protection and restoration of injured organs or tissues.

Breakage of surgical instruments and implants during operative procedures is not uncommon in any surgical discipline. The need for removal and the outcome of leaving the broken instruments and implants in the surgical area have not been described in detail. Few studies have suggested removal if they are lying loosely in the tissues or joint, close to neurovascular structures. Challenges and the amount of time spent in the retrieval of broken instruments and implants are well known among surgeons, so most choose to leave them in situ. We reported a novel method of retrieval of a broken drill bit in the femoral medullary canal during internal fixation of a type C distal femoral fracture.

A mandibular fracture case of twice internal fixation surgery with poor healing was treated by denture prosthodontics in Affiliated Stomatological Hospital of Nanchang University. The profile of maxillofacial region was improved, the masticatory function was enhanced, and the new bone formation was promoted.

This study briefly introduces the revised content of Guidance for Registration of Metallic Bone Plate Internal Fixation System (Revised in 2021) compared to the original guidance, mainly including the principles of dividing registration unit, main performance indicators of standard specification, physical and mechanical performance research, and clinical evaluation. At the same time, in order to provide some references for the registration of metallic bone plate internal fixation system, this study analyzes the main concerns in the review process of these products based on the accumulation of experience combining with the current review requirements.

Locking plate technology offers improved fixation stability in osteopenic bone and for comminuted and periarticular fractures. The additional stability per screw compared with that of conventional nonlocking fixation enhances the application of minimally invasive fracture techniques. The application of locking plates is somewhat more difficult than the placement of conventional plates. Fracture reductions are often done indirectly, the locking screw must be carefully aligned along the axis of the receiving hole to ensure proper tightness, and the length of the plate must be selected carefully. The use of locking plates will likely increase, particularly with the increasing prevalence of osteopenic fractures on our aging population and the increase in high-energy fractures in younger patients severe trauma.

OBJECTIVEThrough reviewing the relevant literature from the past decades, to summarize the assessment and management of fractures of the clavicle, and provide an overview of the clinical results of a range of treatment options.

DATA SOURCESThe data analyzed in this review are mainly from articles included in PubMed and EMBASE, published from 1960 to 2015.

STUDY SELECTIONStudies involving assessment of fractures of the clavicle were reviewed. Further literatures were gathered regarding the conservative and surgical treatment of these fractures, including the methods of fixation and the surgical approaches used. Both conservative and surgical treatments were then compared and contrasted.

RESULTSThrough retrieving and reading the abstract, a total of 42 representative articles were selected, which covered all aspects of the conservative treatment and surgical treatment, and compared the advantages and disadvantages of different treatment options.

CONCLUSIONSAlthough the majority of recent data suggest that surgery may be more appropriate as it improves functional outcome and reduces the risk of complications, we recommend that the treatment should be individually assessed.

OBJECTIVE: To evaluate the efficacy and safety of proximal femoral nail antirotation(PFNA) vs InterTAN nail in treating the elderly intertrochanteric femoral fractures. METHODS: Data of the randomized controlled trials(RCTs) about PFNA vs InterTAN for the treatment of the elderly intertrochanteric femoral fractures were searched in as the Cochrane Library, PubMed, EMbase, Wanfang, CNKI, CBM and VIP from their establishment to January 2018 for collecting. After study selection, assessment and data extraction conducted by two reviewers independently, meta-analyses were performed by using the RevMan 5.3 sofware. The level of evidence was assessed by using the GRADEpro system. RESULTS: Twelve studies involving 1 015 patients were included. The results of meta, analyses showed that: (1)safety indicator: compared with the InterTAN, PFNA had shorter operation time, and less intraoperative bleeding. But InterTAN had less total postoperative complications and internal fixation failure, but there was no significant difference in the operative incision lengths, fracture healing time and other postoperative complications. (2)efficacy indicator: compared with the InterTAN, the Harris hip score was lower after 3 months, but Harris hip score had no significant difference between the two groups after 6, 12 months. Based on GRADEpro system, all the evidence was at level C and weak recommendation(2C). CONCLUSIONS The current evidence indicates that PFNA had a similar effect compared with the InterTAN. But InterTAN could provide better stability against rotation and axial pressure effect, can allow patients do functional exercise early such as ambulation to recovery the hip function. It also had less total postoperative complications and internal fixation failure for the poor quality of the original studies and the limited number of studies, a prudent choice is suggested and more high-quality, large-sample studies are need.

OBJECTIVE: To investigate the relationship between the shape of the lateral wall and the early failure of internal fixation in the fracture of the femoral trochanteric region(FFT). METHODS: Total 295 patients with femoral trochanteric fracture underwent internal fixation from January 2015 to January 2020 were selected. The patients were divided into two groups according to whether there was early internal fixation failure after surgery, 19 patients in the failure group and 276 patients in the normal group. Gender, affected side, age, AO classification, body mass index(BMI), preoperative hemoglobin, X-ray measurement of lower lateral wall thickness, preoperative internal diseases, intraoperative blood loss, postoperative tip apex distance(TAD), postoperative neck shaft angle, operation time and other data were compared between two groups. The shape of the lateral wall was compared between two groups, and the correlation between the shape of the lateral wall and the early internal fixation failure of femoral trochanteric fracture was analyzed. RESULTS: All patients were followed up for more than 1 year. There was no significant difference between two groups in terms of intraoperative blood loss, operation time, postoperative TAD, and postoperative neck shaft angle(P>0.05). At the latest follow-up, the visual anaglue scale (VAS) of the failure group was higher than that of the normal group(P<0.01), and the Harris score of the failure group was lower than that of normal group(P<0.05). The receiver operator characteristic (ROC) curve between shape of lateral wall and failure of early internal fixation of femoral trochanteric fracture was drawn. The critical value of the midpoint lateral wall thickness was 16.5 mm, and the area under the ROC curve was 0.845;The critical value of average sidewall thickness was 16.5 mm, and the area under ROC curve was 0.838;The critical value of the axial area of the sidewall was 7.5 mm, and the area under the ROC curve was 0.826. CONCLUSION The shape of the lateral femoral wall measured by CT could be used as a predictive factor for the early failure of internal fixation of femoral trochanteric fractures. For patients at risk, more reasonable surgical plans and postoperative preventive measures should be developed.
