Preoperative risk factors for early extremity blood supply after repair of major arterial injury / 中华创伤骨科杂志

Objective:To investigate the preoperative risk factors affecting early extremity blood supply after repair of major arterial injury so as to provide clues for prevention of limb ischemia.Methods:The clinical data were retrospectively analyzed of the 139 patients (140 extremities) with major extremity arterial injury who had been admitted to Department of Microsurgery, Orthopaedic Trauma and Hand Surgery, The First Hospital Affiliated to Sun Yat-sen University from January 2003 to December 2019. There were 112 males and 27 females, with a mean age of 30 (20, 44) years. The primary outcome was the early status of blood supply to the injured extremity (48 hours after surgery). Univariate analysis was conducted of such factors as gender, age, ischemia time, injury mechanism, injury site, fracture, soft tissue lesion, and duration of surgery. The significant factors ( P<0.1) were then analyzed by logistic regression, and P<0.05 was considered statistically significant. Results:Ischemia happened in 44 (31.4%, 44/140) extremities within 48 hours after surgery. There were significant differences in injury mechanism, ischemia time, fracture, and soft tissue lesion between patients with and without postoperative extremity ischemia ( P<0.05). Logistic regression analysis indicated that blunt injury ( OR=5.639, 95% CI: 1.068 to 29.761, P=0.042) and soft tissue lesion ( OR=12.568, 95% CI: 3.402 to 46.431, P<0.001) were significant preoperative risk factors affecting the early blood supply after repair of major extremity arterial injury. Conclusion:As blunt injury and soft tissue defect are preoperative risk factors for early extremity ischemia after repair of major extremity arterial injury, surgeons should pay more attention to them when assessing patients and making repair protocols.

Dual split and dislocation----a variant of Schatzker type-I tibial plateau fracture: A case report / 中华创伤杂志(英文版)

Schatzkter type-I tibial plateau fracture is a split fracture of the lateral tibial plateau in sagittal plane, consequent to valgus impaction caused by low velocity of trauma. However, a deep understanding of the different columns of the tibial plateau and patho-mechanisms of the injury led to the unmasking of atypical fractures around the tibial plateau. We have encountered 2 cases with unusual fracture pattern of the lateral tibial condyle caused by road traffic accidents. The fracture pattern and severity of injury deviate from the original description of Schatzker type 1; in view of dual plane split, there is rotation of the posterolateral column fragment along its sagittal plane plus grade-III medial collateral ligament injury. The patients were initially treated with knee spanning external fixator and after a latency of 5 days, definitive fracture specific fixation was done, combined with repair of grade-III medial collateral ligament injury. At the 6 months follow-up both the patients achieved satisfactory knee functions (knee society score case 1: 100 and case 2: 92) and returned to their jobs. The severity of fracture pattern and displacement as described should prompt for examination of associated ligament injury. Because of timely diagnosis, early and appropriate care promised an excellent function outcome even in such a severe nature of knee injury. To prompt the description of injury pattern we coined the name "dual split and dislocation" of lateral tibial plateau, as a complex injury variant of split fracture of lateral tibial plateau fracture.

Application of chen yuangao in the treatment of soft tissue injury of football players / Aplicação de chen yuangao no tratamento da lesão dos tecidos moles de jogadores de futebol / Aplicación de chen yuangao para tratar lesiones de tejidos blandos en jugadores de fútbol

ABSTRACT The treatment of soft tissue injury in football players generally includes physical therapy, anti-inflammatory and analgesic drug treatment, surgical treatment and early rest immobilization. Western medicine treatment of soft tissue injury can quickly heal the wound and relieve pain in a short time. The treatment of traditional Chinese medicine is based on the whole and must seek the root of the disease. It is believed that the occurrence of certain diseases is related to Qi, blood, liver and kidney deficiency, so we should pay attention to the overall adjustment during treatment of symptoms. In view of this, this study analyzed the effect of Chen Yuan ointment, from traditional Chinese medicine, in the treatment of soft tissue injury. Sixty-eight football players who completed ankle ligament reconstruction were divided into four groups according to the type of operation and whether Chen Yuangao-assisted rehabilitation was used or not. The results showed that the Ankle Hindfoot Function Score and the visual analog scale (VAS) score of patients in the fibula brevis tendon reconstruction Chen Yuan ointment group were 98.3 and 0.3, respectively, at the last follow-up, which were better than those in other groups, and had lower pain scores. This result shows that Chen Yuangao has a certain effect in the treatment of soft tissue injury, which can provide a research idea for the rapid rehabilitation of football players.

Efficacy and mechanism of traditional chinese medicine gel in sports-related soft tissue injury / Eficácia e mecanismo do tradicional gel da medicina chinesa em lesões desportivas de tecidos moles / Eficacia y mecanismo del gel de medicina tradicional china en lesiones deportivas de tejidos blandos

ABSTRACT Soft tissue injury is the most common disease in orthopedics, and it is also the most easily neglected disease in sports. Without timely and effective treatment, it is easy to develop into malignant strain and seriously affect life and sports. In view of this, the aim of this study is to analyze the effect and mechanism of traditional Chinese medicine gel in treating such injuries in the light of the characteristics of sports-related soft tissue injury. The right gastrocnemius muscle injury was simulated in 36 adult male rats. Chinese medicine gel and tincture were used to treat it. The contents of interleukin, alanine aminotransferase, blood urea nitrogen and prostaglandin E2 in the blood of rats under different courses of treatment were analyzed to explore recovery in four rats. The results showed that the levels of interleukin and prostaglandin E2 in the blood of rats treated with drugs were significantly lower than those in the control group (p<0.05), indicating that both drugs have obvious therapeutic effects on soft tissue injury. The content of interleukin in the blood of the Chinese medicine gel group was slightly lower than that of the tincture group, indicating that the Chinese medicine gel could affect the recovery of soft tissue injury by affecting leukocyte interleukin. This result is helpful in the treatment of soft tissue injury in sports and to further improve the therapeutic effect of traditional Chinese medicine gel.

Mechanism of Taohong Siwu Decoction in treating soft tissue injury based on UPLC-Q-TOF-MS,network pharmacology and experimental verification / 中国中药杂志

To explore the action mechanism of Taohong Siwu Decoction(THSWD) in the treatment of soft tissue injury(STI) based on UPLC-Q-TOF-MS technique, network pharmacology and experimental verification method. UPLC-Q-TOF-MS technique was used to identify the chemical constituents of THSWD. The active ingredients and predicted target proteins of THSWD were screened out through TCMSP database. Cytoscape software was used to construct the active component-target-pathway network, and STRING database was used for protein interaction analysis. GeneCards and CTD databases were used to screen out relevant targets of STI. GO function and KEGG pathway enrichment analysis were performed through DAVID database. The rat model of STI was constructed, and Western blot was used to verify the effect of THSWD on key targets of relevant pathways. The results showed 40 active ingredients in THSWD, and 141 potential targets and 20 targets of STI. Target enrichment analysis of the active components produced 128 KEGG pathways, which were mainly concentrated in amino acid synthesis and metabolism, disease signaling pathways, apoptosis, inflammation and other relevant pathways. Western blot showed that THSWD intervention could significantly decrease PTGS2, CASP3, NFKB1, p-CASP3 and p-NFKB1, while enhancing the expression of TP53 protein in the STI samples of rats. According to the results of UPLC-Q-TOF-MS, network pharmacology and experimental verification, active ingredients in THSWD may play anti-inflammatory and antioxidant effects in NF-κB signaling pathway and apoptotic pathway, thus playing a role in the treatment of STI.

Objective:To investigate the effect of Ilizarov bone transport technique combined with vancomycin bone cement for treatment of posttraumatic tibial bone infection combined with bone and soft tissue defects.Methods:A retrospective case series study was performed on 11 patients with posttraumatic tibial bone infection combined with bone and soft tissue defects admitted to First Affiliated Hospital of Anhui Medical University from June 2016 to June 2019.There were 7 males and 4 females, with age of 21-56 years [(41.5±12.1)years]. After debridement, the length of bone defect was 4-13.2 cm [(8.1±2.6)cm], and the area of soft tissue defect was 6.5-23.4 cm 2 [(16.2±4.7)cm 2]. All patients were treated firstly with debridement of bone infection and vancomycin loaded bone cement pad filling, followed by Ilizarov technique to repair bone and soft tissue defects. The soft tissue docking time, fracture docking time, external fixation time and external fixation index were recorded. At the last follow-up, Johner wruhs score was used to evaluate the curative effect and American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot score to evaluate the ankle joint function. The postoperative complications were observed. Results:All patients were followed up for 17-23 months [(17.9±4.5)months]. The soft tissue docking time was 48-155 days [(101.7±29.0)days] and fracture docking time was 55-167 days [(111.6±29.5)days]. The external fixation time was 154-450 days [(322.9±86.3)days] with an external fixation index of 31.1-61.5 cm/day [(40.8+ 7.5)cm/day]. At the last follow-up, the results were excellent in 2 patients, good in 4 and fair in 5 based on Johner-Wruhs score. At the last follow-up, the AOFAS ankle hindfoot score was 61-94 points [(76.6±12.7)points], with excellent results in 3 patients, good in 2 and fair in 6. Four patients were treated with secondary operation, and two of them bad docking site nonunion which healed after secondary bone grafting. No free or local transposition flap repair was performed in regardless of soft tissue defect. During the follow-up, there were no complications such as fever, wound weeping, soft tissue necrosis or neurovascular injury.Conclusion:For posttraumatic tibial bone infection combined with bone and soft tissue defects, the Ilizarov bone transport technique combined with vancomycin-loaded bone cement has advantage of shorter operation time, trauma and complications, and can achieve bone lengthening and soft tissue healing simultaneously.

Advantages in instrument-assisted soft tissue mobilization for chronic soft tissue injury / 中国组织工程研究

BACKGROUND: Chronic soft tissue injury is easy to occur during daily living, sports training, treatment and rehabilitation of various acute and chronic diseases. Chronic soft tissue injury can cause pain. If there is no good treatment for the injured soft tissue, it is easy to develop limb dysfunctions (such as limited joint movements) due to have cicatricial contraction and adhesion, limited human activity and participation ability, affecting the quality of daily life activities. It can also reduce the effect of sports training or rehabilitation treatment for athletes and patients with various acute and chronic diseases. In recent years, the treatment of chronic soft tissue injury by instrument-assisted soft tissue mobilization has been widely concerned, which has a positive effect on pain relief after chronic soft tissue injury. This technology has been widely studied abroad, but less in China. OBJECTIVE: To summarize the progress of instrument-assisted soft tissue mobilization in the treatment of chronic soft tissue injury. METHODS: PubMed, WanFang, and CNKI were searched. Relevant literature concerning instrument-assisted soft tissue mobilization, chronic soft tissue injury and pain was retrieved and summarized. RESULTS AND CONCLUSION: Instrument-assisted soft tissue mobilization has a positive effect on the improvement of pain and joint limitation caused by chronic soft tissue injury. It has been proved that instrument-assisted soft tissue mobilization can also improve the soft tissue function of healthy people. Instrument-assisted soft tissue mobilization is suggested to be used in clinical treatment and sports training as a means of treatment and prevention. Current basic research on this technology is still insufficient. In the future, in addition to a large number of clinical randomized controlled studies, we should deeply explore its action mechanism to provide theoretical support for clinical application.

Prefabricated composite tissue flaps for repairing bone and soft tissue defects of the extremities / 中国组织工程研究

BACKGROUND: Prefabricated composite tissue flaps have been used by Bakamjjan for cardiac repair since 1973, but have not been widely used due to technique limitations. Domestic research on prefabricated composite tissue flaps to repair limb bones is rarely reported. OBJECTIVE: To analyze the effects of prefabricated composite tissue flaps in the repair of limb bone and corresponding soft tissue defects. METHODS: New Zealand big rabbit models of bone fracture and soft tissue defect of the extremities were constructed (first operation) and randomly divided into three groups. In group A, prefabricated composite tissue flap was used to treat bone and soft tissue defects of the extremities at 10 days after modeling (second operation). In group B, free femur was used to treat bone and soft tissue defects of the extremities at 10 days after modeling. In group C, the incision was open and sutured with no treatment. General condition, body weight, imaging finding and histological findings were compared between groups. RESULTS AND CONCLUSION: There was 100% survival in all the three groups. Graft displacement was observed in 2 rabbits in the group B, but the deformity healed, which had little effect on the rabbit's mobility. The weight recovery and gain were higher in the group A than in the group B (P < 0.05). The imaging findings showed that a large number of calluses were formed in the group A at 2 weeks after operation, which were bridged in gap at 4 weeks after operation, filled in the defect gap at 8 weeks, and remodeled at 12 weeks. In the group B, a small amount of calluses were formed at 2 weeks after operation, and began to increase at 4 weeks. The femoral cut was obvious. A large number of calluses were formed at 8 weeks after operation, and the defect gap was filled at 12 weeks after operation. In the group C, the callus began to form at 8 weeks after operation, and the defect gap was still present, with osteosclerosis at the two ends. The Lane-Sandhu score was statistically different between the three groups at 8 and 12 weeks after second operation (P < 0.05). Histological observation indicated that a large number of newly formed osteoblasts and bone cells were formed in the group A at 4 weeks after operation, and the tubular structure increased and irregular bone island formed at 8 weeks; new bone formed at 12 weeks, with the presence of the medullary cavity containing yellow bone marrow dominated by adipocytes. In the group B, most of the grafted bones were degraded and absorbed at 4 weeks after operation, and osteoblasts were ossified at 8 weeks. The remaining implanted bones were still visible. Most of the osteoblasts were ossified and became lamellar bones at 12 weeks. In the group C, the defect area was filled with a large amount of fibrous connective tissues at 12 weeks after operation, and there was no bone formation. To conclude, the prefabricated composite tissue flap can be used to repair the bone and soft tissue defects of the extremities, and it has a faster and better therapeutic effect than the traditional free bone repair.

Case Report - Mortality Due to Underestimation of Soft Tissue Injury and Misdiagnosis of Rhabdomyolysis

@#Introduction Rhabdomyolysis is characterized by the breakdown of muscle tissue, and release of intracellular muscle constituents into the blood circulation. The severity of the illness may range from asymptomatic elevation in serum muscle enzymes to a life-threatening disease. One disease may behave differently in different way in different individuals. The first patient was involved in a motor vehicle accident and developed acute kidney injury on the third day of admission. The second patient complained of lower limb weakness, and was discharged with vitamin D supplements. Both patients’ conditions were not properly diagnosed or treated, and succumbed to death. Autopsies were conducted in both cases, in which rhabdomyolysis were diagnosed. This case report emphasizes the importance of making a correct diagnosis of rhabdomyolysis Progression of the disease and its complications should be monitored closely. Timely management may save life in high risk patients.

Objective@#To investigate the clinical therapy for Gustilo type Ⅲ B、ⅢC open fractures with skin and soft tissue defects on the upper extremities.@*Methods@#From July 2014 to July 2016, 19 patients with Gustilo type Ⅲ open fractures (type ⅢB 12 cases , type ⅢC 7 cases) and soft-tissue defects in upper extremity were admitted, including 14 males and 5 females , aged 22 to 59 years (average 42 ). All the cases were treated by staged treatment. In the first stage, early debridement, nerves, vessels and tendons repairment, fixation of the fractures, VSD for the wound were performed. One patient underwent amputation 5 days after first operation. All the other 18 patients received flap transplantion, including 10 anterolateral thigh perforator flaps, 3 latissimus dorsal muscular flaps and 5 free lateral arm flaps.@*Results@#8 patients were followed up for an average duration of 14.5 months(ranged from 7 to 23 months). Partial necrosis happened at the distal end of one anterolateral thigh perforator flap and healed with skin-grafting.1 flap encountered vascular complication which survived with 5cm-in-width skin necrosis at the distal end of the flap after successful surgical exploration. 1 case had superficial infection at wound. The wounds at donor sites were primarily healed except for 1 case with skin graft necrosis and superficial infection. All the other flaps survived completely. The patients received 2-6 operations each. The average hospital stay was 34 days (12-71 days). All Skin flap texture was soft and had varying degrees of pigmentation. The flap sensory recovery was S2 in 4 cases, S3 in 9 cases, S4 in 5 cases. 1 case had obvious scar hyperplasia.@*Conclusions@#Staged surgical treatment in Gustilo type Ⅲ open fractures with soft-tissue defects in upper extremity provide a high survival rate of flaps and satisfactory results. The treatment is well tolerate by patients.

Treatment of Secondary Soft Tissue Compromised Calcaneus Fractures Using a Cannulated Screw and Simple Cerclage Wiring: A Report of Two Cases / 대한족부족관절학회지

Secondary soft tissue injuries can occur from the pressure of the displaced fragment of posterior calcaneal tuberosity in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The soft tissue injury can be prevented by immediate reduction of the displaced fragments. Various techniques can be used to fix the fracture fragments, but the stability of fixation and minimal invasiveness to soft tissue should be considered. This paper reports the successful outcomes of patients with soft tissue compromises in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The fixation technique of a large cannulated screw and simple cerclage wiring is believed to be a useful surgical option for the treatment of secondary soft tissue compromised calcaneal fractures.

Research progress of Chinese medicine treatment for chest contusion / 国际中医中药杂志

Chest contusion is the soft-tissue injury disorders that the external violence directly destroys the chest wall and the soft tissues, causing chest pain, fullness, and symptoms aggravate when the chest moves. Chinese medicine showed many treatments with clinical efficacy. Therefore, Chinese medicine has been widely used in clinics. This paper was to review the research progress of Chinese medicine treatment for chest contusion.

A comparative study of external fixation, expert tibial nail and minimally invasive percutaneous plate osteosynthesis in treatment of AO type 43A tibial fractures / 中华创伤骨科杂志

Objective To compare the clinical effectiveness of external fixation,expert tibial nail (ETN) and minimally invasive percutaneous plate osteosynthesis (MIPPO) in the treatment of AO type 43A tibial fractures.Methods The clinical data of 102 patients with AO type 43A tibial fracture were retrospectively analyzed who had been treated from June 2010 to June 2014.They were 68 men and 34 women,from 18 to 71 years of age (average,36 years).By AO classification,there were 36 cases of type A1,45 ones of type A2,and 21 ones of type A3.External fixation was used in 30 cases,MIPPO in 42,and ETN in 30.The 3 groups were compared in terms of operation time,blood loss,fracture healing time,complications and functional evaluation according to American Orthopaedic Foot and Ankle Society (AOFAS) criteria for middle and fore foot.Results The operation time in external fixation group (72.7 ± 16.1 min) was significantly less than in MIPPO group (101.5±15.1 min) and ETN group (115.0±11.2 min) (P ＜0.05).The blood loss and fracture healing time in external fixation group were (320.6 ±40.8 mL) and (160.6 ± 25.0 days),significantly greater than in MIPPO group (125.5 ± 27.3 mL and 120.3 ± 20.2 days)and ETN group (124.2±25.4mL and 125.5±25.6 days) (P ＜0.05).The total complication rate in external fixation group (53.3％,16/30) was significantly higher than in MIPPO group (9.5％,4/42) and ETN group (10.0％,3/30) (P ＜ 0.05).The total AOFAS excellent to good rate in external fixation group (66.7％,20/30) was significantly lower than in MIPPO group (88.1％,37/42) and ETN group (90.0％,27/30) (P ＜ 0.05).However,there were no significant differences between MIPPO and ETN groups concerning all the above outcome indicators (P ＞ 0.05).Conclusions For AO type 43A tibial fractures,internal fixation should be the first choice.Both MIPPO and ETN can lead to good clinical efficacy.However,in cases where internal fixation is not suitable,external fixation with distal lateral tibial nails at the Chaput tuberosity can obtain satisfactory ankle function.
