OBJECTIVE@#To investigate clinical effect of percutaneous reduction combined with internal fixation of calcaneal nail in treating Sanders typeⅡto Ⅲ calcaneal fractures.@*METHODS@#From July 2017 to August 2019, clinical data of 98 patients with Sanders typeⅡto Ⅲ calcaneal fractures treated were retrospectively analyzed, and divided into observation group and control group according to different surgical methods. In observation group, there were 35 males and 21 females, aged from 23 to 58 years old with an average of (34.50±7.81) years old;29 patients with Sanders typeⅡand 27 patients with Sanders type Ⅲ;30 patients on the left side and 26 patients on the right side;the time from fracture to operation ranged from 1 to 4 days with an average of (3.45±0.54) days;and treated with percutaneous reduction combined with internal fixation of calcaneal nail system. In control group, there were 25 males and 17 females, aged from 25 to 60 years old with an average of (35.27±7.64) years old;23 patients with Sanders type Ⅱ and 19 patients with Sanders type Ⅲ;24 patients on the left side and 18 patients on the right side;the time from fracture to operation ranged from 2 to 5 days with an average of (3.42±0.62) days;and treated with open reduction and internal fixation. Operation time, blood loss, hospital stay, fracture healing time, and postoperative visual analogue scale (VAS) at 1 day, preoperative and postoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Böhler angle, Gissane angle and calcaneus width, and postoperative complications were compared between two groups.@*RESULTS@#All patients were followed up from 13 to 18 months with an average of (15.6±2.2) months. There were significant differences in operation time, blood loss, hospital stay, fracture healing time and postoperative VAS at 1 day between two groups (P<0.05). There was statistical difference in postoperative AOFAS score at 12 months between two groups (P<0.05), and AOFAS score at 12 months after operation was higher than that before operation (P<0.05). According to AOFAS score, 21 patients got excellent result, 30 good and 5 moderate in observation group, and 10 excellent, 22 good, 7 moderate and 3 poor in control group, which had statistical difference between two groups (P<0.05). Postoperative Böhler angle, Gissane angle and calcaneus width at 6 months were better than that before operation between two groups(P<0.05). One patient in observation and 20 patients in control group occurred skin numbness after operation, and 14 patients occurred skin necrosis in control group, there were obvious difference between two groups(P<0.01).@*CONCLUSION@#Compared with open reduction and internal fixation, percutaneous reduction combined with internal fixation system in treating Sanders typeⅡto Ⅲ calcaneal fractures is feasible for fracture repair without waiting for foot deswelling, which could accurately restore normal shape and position of the fractured heel bone, completely eliminate fracture malunion, and reduce postoperative complications. Therefore, it could shorten operation time, hospital stay, fracture healing time, reduce amount of blood loss, promote postoperative recovery, and less complications, high safety, which could be used as a choice of orthopedic surgery for foot and ankle trauma.

Conceptos actuales: ventajas del clavo endomedular para fracturas del húmero proximal / Current concepts: advantages of intramedullary nail for proximal humerus fractures

Las fracturas de húmero proximal (FHP) son una de las fracturas más frecuentes en la población anciana. La reducción abierta y fijación interna (RAFI) generalmente está indicada para pacientes con una FHP desplazada en jóvenes o pacientes mayores con alta demanda funcional y buena calidad ósea. No se ha llegado a un consenso sobre la técnica de fijación ideal. La RAFI con placas ha sido la más utilizada, pero se han reportado altas tasas de reintervenciones y complicaciones globales en la literatura. La necesidad de agregar técnicas de aumentación a la RAFI con placas bloqueadas en fracturas complejas puede resultar en un tiempo quirúrgico más largo, abordajes extensos y mayores costos. Debido a esto, se hace necesario considerar otras opciones para la osteosíntesis de FHP. Con una mayor comprensión de los mecanismos de falla de la osteosíntesis, la fijación intramedular se ha convertido en una opción de tratamiento aceptada para las FHP con ventajas biomecánicas y biológicas. La fijación intramedular para las FHP ha demostrado menor tiempo quirúrgico, sangrado intraoperatorio, tiempo hasta la unión ósea y menores tasas de infecciones, que las placas bloqueadas. La fijación intramedular es una opción válida para que las fracturas complejas se resuelvan con un implante que por sí solo puede satisfacer en gran medida todas las necesidades de aumento requeridas por una placa bloqueada

Proximal humeral fractures are one of the most frequent fractures in the elderly population. Open reduction and internal fixation (ORIF) is generally indicated for young patients and older patients with high functional demands and good bone quality. No consensus has been reached regarding the ideal fixation technique. Although ORIF with plates is the most widely used technique, high re-intervention rates and global complications with locked plate fixation have been reported in the literature. Addition of augmentation techniques to locked plate fixation in complex fractures may result in longer surgical times, extensive approaches, and higher costs. Therefore, considering other options for ORIF is necessary. With a greater understanding of the mechanisms of fixation failure, intramedullary fixation has become the accepted treatment option for proximal humeral fractures considering the specific biomechanical and biological advantages. Compared with ORIF with locked plates, intramedullary fixation for proximal humeral fractures has low surgical time, intraoperative bleeding, time to bone union, and rate of infections. Intramedullary fixation is a valid option to resolve complex fractures with an implant that may largely supply all the augmentation requirements of a locked plate.

Intramedullary fixation versus plate fixation in the treatment of displaced mid-shift clavicle fractures: A meta-analysis / 中国组织工程研究

BACKGROUND: Elastic intramedullary nail and steel plate are two commonly used instruments for clavicle fracture, However, there are few comparative studies on the advantages and disadvantages of them. OBJECTIVE: To systematically evaluate the treatment effects of intramedullary fixation or plate fixation for displaced mid-shift clavicle fractures. METHODS: Articles about the treatment effects of intramedullary fixation or plate fixation for displaced mid-shift clavicle fractures were searched in PubMed, Embase, Science Direct and Cochrane Library, CNKI, WanFang and VIP databases from inception to March 2017. Two reviewers independently screened the articles, extracted data and evaluated the bias risk in the included studies according to the inclusion and exclusion criteria. Meta-analysis was performed using ReMan 5.3 software. RESULTS AND CONCLUSION: (1) A total of 21 studies were included, with 859 patients in the intramedullary fixation group and 831 patients in the plate fixation group. (2) The result of meta-analysis showed that the operation time [MD=-18.62, 95%CI (-20.75, -16.49)], blood loss [MD=-56.23, 95%C/(-68.02, -62.44)], incision length [MJ=-5.53, 95%C/(-6.56, -4.49)], hospitalization time [MD=-1.01, 95%C/(-1.13, -0.89)], and healing time [MD=-1.39, 95%C/ (-1.98, -0.80)] in the intramedullary fixation group were better than those of the plate fixation group. (3) At 6 months after surgery, the Disabilities of the Arm, Shoulder and Hand scores in the intramedullary fixation group were better than those in the plate fixation group (F < 0.05). The scores showed no significant difference between two groups at 12 months after surgery. Major complications [OR=0.61, 95%C/ (0.39, 0.93)] in the intramedullary fixation group were less than those in the plate fixation group. Minor complications and implant removal were similar between two groups. (5) Meta-analysis results imply that elastic intramedullary nail fixation for treating displaced mid-shift clavicle fractures is superior to plate fixation in surgery-related indexes, functional recovery and fracture healing, which can provide effective evidence for its clinical application.

Internal fixation strategies for different lateral wall types of intertrochanteric fractures of the femur / 中国组织工程研究

BACKGROUND: The importance of the lateral wall of the femoral trochanter in the intertrochanteric fracture has been paid more and more attention. The research on the classification of the external wall in guiding clinical operation has become a hot issue. OBJECTIVE: To review the treatment strategies of different lateral wall types of intertrochanteric fractures, and the selection of the built-in materials, provide reference and help for future clinical research. METHODS: The first author searched the Chinese database ofWanfang and China National Knowledge Infrastructure with the keywords of “intertrochanteric fracture of femur; lateral wall of femoral trochanter; fracture classification; fracture fixation, internal; implant; intramedullary fixation; extramedullary fixation; complications; elderly; prognosis”. Meanwhile, PubMed English database was retrieved with the keywords “intertrochanteric fracture of femur; lateral wall of femoral trochanter; fracture classification; fracture fixation, internal; implant; intramedullary fixation; extramedullary fixation; complications; elderly; prognosis”. The retrieval time was from May 2009 to May 2019. A total of 166 literatures were retrieved. According to the inclusion and exclusion criteria, 47 literatures were selected as the research object and summarized. RESULTS AND CONCLUSION: (1) During the surgical treatment of intertrochanteric fracture of the femur, intramedullary fixation system and extramedullary fixation system have their own advantages and disadvantages. After full analysis of lateral femoral trochanter wall classification and reasonable preoperative evaluation, it is a combination of theory and practice. Signing, correctly assessing the severity of fractures and judging the prognosis, and fully preoperative evaluation can greatly help the patient’s treatment effect and prognosis. (2) It is a basic quality of doctors and a responsible attitude towards patients to formulate different treatment plans according to their economic conditions and physical qualities. “Individualization” has become the future development trend. (3) There are still many disputes in the treatment of intertrochanteric fractures. More clinical research and data support are needed in the future to solve and improve it.

Clinical significance of external wall of femoral intertrochanteric fracture and the treatment of internal fixation / 中国组织工程研究

BACKGROUND: The concept of the lateral wall as a hot area has emerged in recent years, and has great guiding significance for the treatment of intertrochanteric fractures. OBJECTIVE: To review the definition, scope, thickness of the lateral wall and its important role in the surgical treatment of intertrochanteric fractures. METHODS: The authors searched Wanfang, CNKI, PubMed, and Web of Science. The search terms were “intertrochanteric fracture, lateral wall, fracture fixation” in Chinese and English. The retrieved documents were sorted, analyzed and summarized. RESULTS AND CONCLUSION: (1) The definition, scope, thickness and measurement method of the lateral wall and its clinical significance were sorted out. (2) Classification criteria based on lateral intertrochanteric fractures of the femur were summarized. (3) In terms of treatment, four kinds of treatment methods: Extramedullary fixation, intramedullary fixation, artificial joint replacement and other treatment methods were listed. Causes and treatment of fracture of lateral wall during and after operation were analyzed. (4) The results showed that the integrity of the lateral wall directly affected the stability of the internal fixation, even the success of the internal fixation. The complete lateral wall can prevent the distal femur from moving inward and the head pin from withdrawing, and prevent the coxa varus deformity. Clinicians should make use of detailed imaging examination, analyze fracture types, comprehensively consider various factors, and select appropriate repair methods.

Modified Bouquet Technique for Treatment of Metacarpal Neck Fractures

PURPOSE: The purpose of this study was to report the clinical outcome of "modified Bouquet technique", as a simple and effective internal fixation with Kirschner-wire for the metacarpal neck fractures. METHODS: Sixty-seven patients with metacarpal neck fracture treated by modified Bouquet technique were retrospectively reviewed. The operation time and removal time were evaluated. For radiologic evaluation, posterior angulation of fracture and metacarpal shortening were measured pre and postoperatively. For clinical evaluation, range of motion of metacarpophalangeal joint, Green and O'Brien score were evaluated. RESULTS: Preoperative neck shaft angle of metacarpal bone was 46.0° and length of metacarpal bone was 51.2 mm, and postoperative neck shaft angle was 24.4° (p=0.003) and length of metacarpal length was 52.8 mm (p=0.031) in average. The mean range of motion was 86.6° and Green and O'Brien score was 96.1 points at last visit. We had one complicated case with type II complex regional pain syndrome of affected hand with hypertrophic scar formation. CONCLUSION: Modified Bouquet technique for metacarpal neck fracture is a good method using just two K-wires, plier and mallet without electric devices in short operation time. The technique can correct angulation of fracture site, rotation of finger and metacarpal shortening by controlling inserted K-wires with high bone union rate with less joint stiffness.

Effect of minimally invasive percutaneous plates versus interlocking intramedullary nailing in tibial shaft treatment for fractures in adults: A meta-analysis

OBJECTIVE: The aim of this article was to determine the effects of minimally invasive percutaneous plates versus interlocking intramedullary nailing in the treatment of tibial shaft fractures in adults. METHOD: Literature searches of the Cochrane Library, PubMed, EMBASE, the Chinese Biomedical Literature database, the CNKI database, Wanfang Data, and the Weipu Journal database were performed up to August 2013. Only randomized and quasi-randomized controlled clinical trials comparing the use of percutaneous plates and interlocking intramedullary nails for tibial shaft fractures were included. Data collection and extraction, quality assessment, and data analyses were performed according to the Cochrane standards. RESULTS: Eleven trials were included. Compared with interlocking intramedullary nailing, minimally invasive percutaneous plates shortened fracture healing time and resulted in lower rates of postoperative delayed union and pain. There was no significant difference between the two methods with regard to the rates of excellent and good Johner-Wruh scoring, the rate of reoperation, and other complications. CONCLUSIONS: Overall, insufficient evidence exists regarding the effects of minimally invasive percutaneous plates versus interlocking intramedullary nailing in the treatment of tibial shaft fractures in adults. Low-quality evidence suggests that minimally invasive percutaneous plates could shorten fracture healing time, decrease the rate of postoperative delayed union, and decrease pain levels compared with interlocking intramedullary nailing. There is no significant difference between the two groups in terms of functional recovery scores, reoperation, and other complications. Further research that includes high-quality randomized controlled, multicenter trials is required to compare the effects of minimally invasive percutaneous plates versus interlocking intramedullary nailing in the treatment of tibial shaft fractures in adults. .

Treatment of Metacarpal Shaft Fractures with Retrograde Intramedullary Kirschner-Wire Fixation

PURPOSE: The purpose of this study is to evaluate the clinical results of retrograde intramedullary fixation of metacarpal shaft fractures using two pre-bent Kirschner wires. MATERIALS AND METHODS: Between March 2006 and May 2008, 19 cases (17 patients) of metacarpal shaft fractures were treated with the retrograde intramedullary Kirschner-wire fixation and followed at least one year. The exclusion criteria were thumb metacarpal fractures, comminuted fractures and irreducible metacarpal spiral shaft fracture by closed manipulation. At final follow up all the cases were assessed with total active motion(TAM), rotational deformity, bony union and angular deformity based on the plain radiographes. RESULTS: At the last follow-up, all cases achieved bony union. Five cases showed less than 5degrees of dorsal angular deformity. The average union period was 6.3 weeks (range, 5-9weeks). Fifteen cases (79%) showed excellent results, four cases good results based on TAM. No case showed rotational deformity. Two cases had skin irritation by distal wire end, which was subsided after wire removal. CONCLUSIONS: In patients with a metacarpal shaft fracture, retrograde intramedullary fixation using two pre-bent K-wires can provide satisfactory clinical results.

Intramedullary Kirschner Wire Fixation for Forearm Fractures in Children

PURPOSE: To evaluate the clinical and radiological results of intramedullary fixation using Kirschner wires (K-wires) for the treatment of unstable forearm fractures in children. MATERIALS AND METHODS: Forty-three children who underwent intramedullary fixation using K-wires for the treatment of a forearm bone fracture were evaluated. The rodiological results were based on the time to union and angular deformity at last follow-up. The clinical results were analyzed according to Price criteria. RESULTS: Average union time was 6.9 weeks. Preoperatively, average angular deformity of radius is 11.4 degrees in anteroposterior (AP) view and 15.3 degrees in lateral view. In case of the ulna, arerage angular deformity was 8.3 degrees in AP view and 12.7 degrees in lateral view. At last follow up, average angular deformity of radius was 1.5 degrees in AP view and 1.6 degrees in lateral view. In case of the ulna, arerage angular deformity was 1.3 degrees in AP view and 2.5 degrees in lateral view. According to the criteria of Price et al., 42 patients (97%) were excellent and one patient (3%) was good. No specific complication was observed. CONCLUSION: An intramedullary fixation using K-wires is an attractive treatment option for unstable forearm fractures in children in terms of safety, excellent cosmesis, short hospitalization, easy hardware removal, and providing excellent radiological and clinical results.

RESULTS: Average length of follow up was 13.9 months with mean age of 10.8 years and the time to union was 5.2 weeks. There were no angular deformity and fuctional results were excellent in all cases. There were 5 cases of soft tissue irritation of nail insertion site as post operative complication which was resolved after nail removal. CONCLUSION: Flexible intramedullary for pediatric forearm bone fractures is an effective and safe method which gives a good functional outcome.

Bouquet Pin Intramedullary Nail Technique of the 5th Metacarpal Neck Fractures

PURPOSE: To evaluate radiologic and clinical results of bouquet pin intramedullary nail technique for the 5th metacarpal neck fracture. MATERIALS AND METHODS: Between April, 2005 and February, 2006, 17 patients treated by bouquet pin intramedullary nail technique for the 5th metacarpal neck fracture were evaluated. All patients were reviewed clinically and radiologically after operation. RESULTS: All of 17 cases of fractures were completely united. In the anteroposterior radiographs, the average of preoperative angulation was corrected from 34.4° to 5.2°. Also, in the oblique radiographs, radiographic results of angulation correction were satisfactory which was corrected from 44.2° to 11.7°. Although, the averages of difference between postoperative and final follow-up angulations were 1.5° in the anteroposterior radiographs and 0.9° in the oblique radiographs, they were not statistically different. All patients were excellent clinically except 1 patient who has moderate joint stiffness after operation. CONCLUSION: Selecting of appropriate patients who is indicated, bouquet pin intramedullary nail technique for the 5th metacarpal neck fracture could be a good treatment method without complications.

The Shortening and Rotational Deformity after Closed Intramedullary Nailing of Femur Shaft Fracture: According to Winquist-Hansen classification

PURPOSE: This study evaluated the shortening and rotational deformity after closed intramedullary nailing of femur shaft fracture according to Winquist-Hansen classification type. MATERIALS AND METHODS: This study was based on 98 cases who received cloased intramedullary fixation about their femur shaft fractures between January 2000 and October 2005 with minimum 12 months follow up. The rotational deformity was analysed by Yang's method (45 cases) preoperatively and postoperatively, and the shortening by orthoradiogram (55 cases). Furthermore we analysed other complications, for example nonunion, infection, and metal failure. RESULTS: We found more than 15 degrees anteversion difference of both femurs in 10 cases. Among them, 9 cases were classified to type 3, 4. According to Winquist-Hansen classification, rotational deformity ranged from 3.7° (Type 1) to 8.9° (Type 4). More than 2 cm leg length discrepancy (LLD) was found in 9 cases, all of them were classified as Winquist-Hansen classification type 3, 4. In the type 1, LLD was checked as 3.2 mm and type 4, 14.2 mm. CONCLUSION: To prevent the shortening and rotational deformity after intramedullary fixation of Winquist-Hansen classification type 3, 4 femur shaft fracture, intraoperatively the exact contralateral femoral anteversion and length should be checked.

The patients were followed up over a period of at least 12 months. The final postoperative outcome was analyzed with the clinical outcomes using Kang's criteria, radiological union time and operation time. RESULTS: The clinical outcome that was good or excellent according to the Kang's criteria showed a distribution of 88% in the group using the plate with 29 cases out of total 33 cases, 91% in the group using the Steinmann pin with 32 cases out of total 35 cases. The mean radiological union time was 8.9 weeks in the group using the plate, 9.1 weeks in the group using Steinmann pin. The mean operation time was 72 minutes in the group using the plate, whereas was 18 minutes in the group using Steinmann pin. CONCLUSION: In the treatment of adult clavicle shaft fracture, two groups did not show a significant statistical difference in clinical and radiological outcomes. However, the operation time and postoperative functional recovery was significantly shorter and faster in the group using Steinmann pin. Additionally economic and cosmetic aspect was more satisfactory in the group using Steinmann pin.
