ABSTRACT

OBJECTIVE@#To explore the efficacy of a novel sternoclavicular hook-plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular joint.@*METHODS@#Retrospective analysis of 13 cases of proximal clavicle fracture with dislocation of sternoclavicular joint treated with sternoclavicular hook-plate from June 2011 to January 2019 in our department. There were 9 males and 4 females, aged 26 to 78 years old, with an average age of (54.08±13.91) years old. All the patients had closed injuries without damage of blood vessels and nerves. The patient's operation time, intraoperative blood loss, hospital stay time, and postoperative complications were recorded. Fracture healing and reduction were evaluated according to X-ray and CT after operation. Constant-Murley score and Rockwood sternoclavicular joint score were used to evaluate limb function at 12 months after operation.@*RESULTS@#All the patients were treated with sternoclavicular hook-plate. The operation time ranged from 50 to 76 min, with a mean of (54.08±13.91) min. The intraoperative blood loss ranged from 20 to 56 ml, with a mean of (46.08±11.15) ml. The hospital stay time ranged from 6 to 14 d, with a mean of (8.31±2.32) d. X-ray and CT examination on the second day after operation showed that all fractures and dislocations were anatomically reduced, and shoulder joint function exercise was performed early. All patients were followed up, and the duration ranged from 12 to 24 months, with a mean of (16.77±4.63) months. The healing time ranged from 9 to 13 d, with a mean of (11.00±1.75) d;and the bone healing time ranged from 3 to 4 months, with a mean of (3.65±0.46) months. There were no complications such as infection, internal fixation failure and nerve injury. At 12 months follow-up, the constant Murley score ranged from 78 to 100, with a mean of 87.83± 11.26; and Rockwood score ranged from 9 to 15, with a mean of 13.70±1.85. Among them, 11 cases were excellent, 1 case was good, and 1 case was general.@*CONCLUSION@#The use of the novel sternoclavicular hook-plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular joint is an effectively internal fixation with high safety, allowing early functional exercise for patients.

ABSTRACT

<p><b>OBJECTIVE</b>To compare clinical outcomes of external and posterior malleolar fractures associated with compressive articular surface through posteriorlateral incision and posteriormedial incision.</p><p><b>METHODS</b>From January 2012 to January 2015, 52 patients with external and posterior malleolar fractures associated with compressive articular surface were treated by interfix. Among them, 24 patients were treated through posteriourlateral incision, including 16 males and 8 females, aged from 20 to 65 years old with an average of(35.2±6.4);28 patients were treated through posteromedi and posterior lateral incision, including 18 males and 10 females, aged from 22 to 62 years old with an average of(36.4±4.8). Operation time, blood loss, length of incision, times of X-ray exposure and complications between two groups were recorded and compared, AOFAS scores were applied for evaluate clinical outcomes.</p><p><b>RESULTS</b>All patients were followed up, group A were followed up from 13 to 55 months with an average of (27.5±2.5) months;group B were followed up from 12 to 54 months with an average of (28.5±2.4) months. All fractures were obtained good reduction, and the healing time ranged from 10 to 16 weeks with an average of 12 weeks. Two patients in group B occurred incision infection, and 1 patient occurred screw loosening; while no incision infection occurred in group A, and 1 patient occurred screw loosening. There were statistical significance in operation time, blood loss, times of X-ray exposure and complications between two group;while no significant difference in ankle AOFAS score between two groups.</p><p><b>CONCLUSIONS</b>Compared with reduction through achilles tendon, reduction for external and posterior malleolar fractures combined with compressive articular surface through tibiafibular fractures region has advantages of less blood loss, shorter operation time, less times of X-ray exposure, good recovery of ankle joint function, especially in treating external and posterior malleolar combined with compressive articular surface which could not obtained good reduction through normal pathway.</p>

ABSTRACT

Immune-mediated inflammatory injury is an important feature of the disease aggravation of hepatitis B virus-related acute-on-chronic liver failure (ACLF). Toll-like receptors (TLRs) have been shown previously to play a pivotal role in the activation of innate immunity. The purpose of this study was to characterize the TLR4 expression in peripheral blood mononuclear cells (PBMCs) of ACLF patients and its possible role in the disease aggravation. Twelve healthy subjects, 15 chronic HBV-infected (CHB) patients and 15 ACLF patients were enrolled in this study. The TLR4 expression in PBMCs and T cells of all subjects was examined by real-time PCR and flow cytometry. The correlation of TLR4 expression on T cells with the markers of disease aggravation was evaluated in ACLF patients. The ability of TLR4 ligands stimulation to induce inflammatory cytokine production in ACLF patients was analyzed by flow cytometry. The results showed that TLR4 mRNA level was upregulated in PBMCs of ACLF patients compared to that in the healthy subjects and the CHB patients. Specifically, the expression of TLR4 on CD4(+) and CD8(+) T cells of PBMCs was significantly increased in ACLF patients. The TLR4 levels on CD4(+) and CD8(+) T cells were positively correlated with serum total bilirubin (TBIL), direct bilirubin (DBIL), international normalized ratio (INR) levels and white blood cells (WBCs), and negatively correlated with serum albumin (ALB) levels in the HBV-infected patients, indicating TLR4 pathway may play a role in the disease aggravation of ACLF. In vitro TLR4 ligand stimulation on PBMCs of ACLF patients induced a strong TNF-α production by CD4(+) T cells, which was also positively correlated with the serum markers for liver injury severity. It was concluded that TLR4 expression is upregulated on T cells in PBMCs, which is associated with the aggravation of ACLF.
