ABSTRACT

Objective:To compare the biomechanical properties of triangular supporting fixation and Gamma nail fixation for intertrochanteric fractures of the femur.Methods:The femoral CT imaging data provided by a healthy adult male volunteer aged 40 years, height 172 cm, and weight 75 kg were used to reconstruct the femur model using Mimics 21.0 software and Geomagics 2013 software. Evans type I intertrochanteric fracture models were established using UG12.0 software, and Gamma nail and triangular supporting intramedullary nail models were reconstructed to simulate intertrochanteric fracture internal fixation, respectively. In Abaqus software, two internal fixation models of Gamma nail and triangular supporting intramedullary nail in standing state are simulated, and the stress peaks of the main nail, fixation screw and bone substance were collected, also the stress peak of supporting screw of the triangular supporting intramedullary nail is obtained. Additionally, the maximum displacement of the fracture model fixed by Gamma nail and triangular supporting intramedullary nail is measured.Results:Under the load of 1 200 N, the peak stress of the two fracture internal fixation models was located in the main nail, in which the peak stress of the triangular supporting intramedullary nail was 233.73 MPa, which was 11.9% lower than that of the Gamma nail (265.21 MPa); the peak stress of the fixation screw was located in the contact area between the pressure screw and the main nail, which was 23.2% lower in triangular supporting intramedullary nail than that of the Gamma nail (138.86 MPa vs. 180.75 MPa); the peak stress of the bone model was located in the medial cortex of the femur, which was 61.67 MPa and 32.38 MPa, respectively, 47.5% lower in the triangular supporting intramedullary nail than that of the Gamma nail; the peak stress of the supporting screw in the triangular supporting intramedullary nail was 92.04 MPa. The maximum displacement of the fracture model fixed with triangular supporting intramedullary nail was 17.34 mm, which was 10.5% less than the maximum displacement of the fracture model fixed with Gamma nail (19.37 mm). Conclusion:Compared with Gamma nail, triangular supporting intramedullary nail fixation can significantly improve the stability of intertrochanteric fractures and stress distribution as well as reduce stress peak and stress concentration area, which is helpful to improve the efficacy of intertrochanteric fractures.

ABSTRACT

Objective:To compare the biomechanical properties between triangular supporting fixation and conventional dynamic hip screw (DHS) fixation in the treatment of femoral intertrochanteric fractures.Methods:Eight pairs of 16 femoral specimens with an average death age of 51.9 years were used in this study. After thawing, they were randomly divided into an experimental group ( n=8) and a control group ( n=8) according to the left or right laterality. They were made models of femoral intertrochanteric fracture of AO 31-A1 type with strain gauges pasted. The experimental group was subjected to fixation with double triangu-lar supporting and the control group conventional DHS fixation to achieve anatomical reduction. The specimens were then mounted onto a biomechanical testing machine and subjected to loading till 400 N at a rate of 10 N/s. The values of overall deformation of the specimens and strain at 16 selected sites were recorded and compared between the 2 model groups. Results:Under the load of 400 N, the overall deformation was (0.31±0.13) mm for the experimental group and (0.49±0.21) mm for the control group, showing a significant difference ( t=-2.456, P=0.023). The strain values in front of femoral neck, upon front fracture line, at inferior-lateral, inferior-median and inferior-interior sites of front fracture line, at the root of anterior fixation screw, below medial femoral neck fracture line, behind femoral neck, at superior-lateral, superior-median and superior-interior sites of posterior fracture line, below posterior fracture line, at superior and inferior roots of posterior fixation screw, at points parallel to the fixation screw in front of and behind femoral shaft were, respectively, -244.90, 13.16, -71.77, -124.38, -366.89,121.62, -10.94, -166.00, -54.93, -367.38, -608.93, -69.09, 326.50, 133.14, 52.97, and -185.82 in the experimental group and -24.62, -40.39, -36.99, -120.97, -486.38, 99.20, 35.36, -205.67, -74.30, -566.01, -1, 085.40, -77.41, 334.34, 114.08, 38.50, and -235.74 in the control group. Internal fixation failure occurred in one specimen in the control group after 1,759 cycles of loading but in none in the experimental group. Conclusion:For femoral intertrochanteric fractures, double triangular supporting fixation may result in less overall deformation and is more consistent with the normal biomechanical conduction of the femur than conventional DHS fixation.

ABSTRACT

@#Objective    To investigate the optimal treatment scheme for the first primary spontaneous pneumothorax (PSP) in young patients. Methods    The clinical data of 171 patients with the first PSP were retrospectively analyzed who were treated in Huaihe Hospital of Henan University between November 2011 and October 2017. There were 157 males and 14 females with a median age of 18 years at onset and a median body mass index of 18.51 kg/m2. According to the treatment methods, they were classified into two groups, a conservative treatment group (a non-surgical group, n=86) and a surgical group (n=85). The characteristics including clinical data, efficacy evaluation criteria, complications and recurrence of the two groups were analyzed. Results    As a result, 73.68% of the patients suffered PSP in their daily routine. The drainage duration in the non-surgical group was longer than that in the surgical group (4 d vs. 3 d, P=0.008). There was no statistical difference in the success rate of lung re-expansion between the two groups (98.85% vs. 100.00%, P=1.000). The proportion of the surgical group using postoperative analgesic drugs was higher than that in the non-surgical group (48.23% vs. 10.46%, P=0.000). The recurrence rate of the surgical group was lower than that of the non-surgical group (3.53% vs. 46.51%, P=0.000). No relationship between smoking and recurrence of pneumothorax was found in both groups (P=0.301, P=1.000). The success rate of lung re-expansion in the non-surgical group was not statistically different between the 24F subgroup and the 12F subgroup (39/39 vs. 33/34, P=0.458). No advantage of intraoperative pleural fixation was found in the surgical group (P=0.693). Conclusion    Thoracoscopic surgery is the first choice for the treatment of the first PSP in young patients.

ABSTRACT

Objective:To understand and verify the biomechanical mechanism of tibial plateau Hoffa (coronal) fracture by simulating high-altitude falls and traffic injuries using knee joint specimens.Methods:Ten specimens of lower limb knee joint were used. They were from 6 males and 4 females, with an average age of 57.4 years (from 42 to 65 years). They were divided into 2 equal groups: one subjected to simulation of high-altitude falls (fall group) and the other to simulation of traffic injury (traffic injury group). After injury simulation, standard orthographic and lateral X-ray examinations and CT scans were performed of the knee joints in the extended position to observe whether there was a fracture, where the fracture occurred, and how the fracture line went.Results:A tibial plateau coronal fracture was successfully simulated in 6 cases, but not in the other 4 cases. The failure was attributed to femoral fractures and other types of tibial plateau fracture. In the 3 successful fractures simulated by high-altitude fall, the fracture line was located all on the posterior medial side, involving the posterior 1/3, 2/5, and 1/2 of the tibial plateau, respectively. The fracture line and the coronal plane formed angles of 21°, 19° and 12°, respectively. The fracture was not shown on X-ray film in one case which was a posterior medial fracture on CT. In the other 3 successful fractures simulated by traffic injury, the fracture line involved 1/6, 1/4 and 1/3 of the posterior tibial plateau, respectively. The angles between the fracture line and the coronal plane were 47°, 56° and 63°, respectively. One case showed no obvious fracture signs on the X-ray but a coronal fracture on CT.Conclusions:This study has confirmed for the first time that both high-altitude falls and traffic injuries can cause coronal fractures of the tibial plateau which vary significantly in the extent of involvement and morphology. X-rays are not sufficient to fully diagnose this type of fractures, suggesting that patients with a clear history of knee flexion or axial violence injury should be routinely scanned by CT to reduce risks of missed diagnosis and insufficient treatment.

ABSTRACT

Objective To compare the clinical outcomes between percutaneous minimally invasive suture versus conventional open suture for acute closed rupture of Achilles tendon.Methods A prospective study was performed in the 68 patients who had been treated for acute occlusive rupture of Achilles tendon from November 2010 to November 2013 at Department of Orthopedic Trauma, The Third Affiliated Hospital to Soochow University. They were randomly assigned by the sequence of medical attention to receive percutaneous minimally invasive suture or conventional open suture. In the conventional group, there were 31 men and 3 women with an average age of 37.0 ± 10.0 years; in the minimally invasive group, there were 30 men and 4 women with an average age of 36.4 ± 9.4 years. The 2 groups were compared in terms of operation time, intraoperative bleeding, postoperative wound infection, postoperative skin necrosis and ankle-hindfoot score of American Orthopaedic Foot and Ankle Society ( AOFAS ) . Results All the 68 cases were fol-lowed up for an average of 21.26 months ( from 6 to 36 months ). There were no significant differences between the 2 groups in operation time ( 75.0 ± 5.3 min versus 64.8 ± 3.8 min ) or in rate of postoperative local in-fection [ 2.9% ( 1/34 ) versus 14.7% ( 5/34 ) ] ( P > 0.05 ). The minimally invasive group had significantly less intraoperative bleeding ( 12.0 mL ) , a significantly lower rate of skin necrosis [ 2.9% ( 1/34 ) ] and significantly higher AOFAS scores at 6 ( 90.5 ) , 12 ( 91.5 ) and 24 months ( 93.5 ) postoperatively than the conventional group did ( 80.0, 81.0 and 82.5, respectively ) ( all P <0.05 ). Conclusion Percuta-neous minimally invasive suture is recommendable for treatment of acute closed rupture of Achilles tendon because it leads to less intraoperative bleeding, better postoperative functional recovery and lower incidence of postoperative skin necrosis.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the changes of relative telomere length (RTL) of peripheral blood (PB) CD3⁺, CD3⁺CD4⁺, CD3⁺CD8⁺T lymphocytes, CD19⁺B lymphocytes and bone marrow (BM) CD34⁺ cells and its association with disease severity in untreated patients with immuno-related pancytopenia (IRP).</p><p><b>METHODS</b>The PB CD3⁺ , CD3⁺ CD4⁺ , CD3⁺ CD8⁺ T lymphocytes, CD19⁺ B lymphocytes, and BM CD34⁺ cells were purified by magnetic activated cell sorting (MACS), and RTL were measured with flow-fluorescence in situ hybridization (FLOW-FISH).</p><p><b>RESULTS</b>The RTL of CD3⁺, CD3⁺CD4⁺ , and CD3⁺CD8⁺T lymphocytes in untreated IRP patients were (27.754 ± 16.323)%, (7.526 ± 3.745)% and (25.854 ± 14.789)%, respectivly, which were significantly shorter than those in healthy-controls (54.555 ± 19.782)%, (12.096 ± 2.805)%, and (38.367 ± 4.626)% (P<0.05). The RTL of CD19⁺ lymphocytes in untreated IRP patients was (22.136 ± 16.142)%, which was significantly shorter than that in healthy controls (42.846 ± 16.353)% (P<0.01). There was no significant difference of BM CD34⁺ cells RTL between the untreated IRP patients (22.528 ± 21.601)% and the healthy controls (23.936 ± 19.822)% (P>0.05). There were significantly positive correlations between the RTL of B lymphocytes and the count of white blood cell (r=0.706, P=0.015).

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the mechanisms underlying bone marrow damage by iron overload in pancytopenic patients with positive BMMNC-Coombs test (IRP).</p><p><b>METHODS</b>Twenty-one iron overloading, 26 non-iron overloading IRP patients and 10 normal controls were enrolled in this study. The expressions of ROS, Bcl-2, Caspase-3 and apoptosis of BMMNC were analyzed by flow cytometry (FCM). Antioxidants were added to iron overloading IRP BMMNC, and then the changes of indices above were detected by FCM. The number and apoptosis of T lymphocytes of IRP patients were also detected.</p><p><b>RESULTS</b>ROS and apoptosis of BMMNC, myelocytes, erythrocytes and stem cells of iron overloading IRP patients were significantly higher than that of non-iron overloading IRP ones and normal controls (P < 0.05). The expressions of Bcl-2 on BMMNC, erythrocytes and stem cells of iron overloading IRP patients were significantly lower than those of non-iron overloading IRP ones (P < 0.05). The levels of Caspase-3 on myelocytes, erythrocytes and stem cells of iron overloading IRP patients were significantly higher than those of non-iron overloading IRP ones and normal controls (P < 0.05). After treatment with antioxidants, the expressions of ROS, Caspase-3 and apoptosis of iron overloading IRP BMMNC significantly decreased, but opposite for Bcl-2. The percentages of CD4(+) lymphocytes [ ( 40.86 ± 8.74)%] and CD4(+)/CD8(+) (1.44 ± 0.36) in PB of iron overloading IRP patients were significantly higher than that of non-iron overloading IRP ones [(35.96 ± 7.03)% and 1.14 ± 0.37] and normal controls [(28.00 ± 6.73)% and 0.79 ± 0.21], respectively (P < 0.05), as opposite for CD8(+) lymphocytes (P < 0.05). The apoptosis of CD8(+) lymphocytes [(27.35 ± 10.76)%] and the ratio of CD8(+) apoptosis/CD4(+) apoptosis (2.51 ± 0.81) in BM of iron overloading IRP patients were significantly higher than those of non-iron overloading IRP ones [(15.47 ± 8.99)%] and normal controls (1.39 ± 0.47), respectively (P < 0.05). The apoptosis of erythrocytes and stem cells coated with auto-antibodies in BM of iron overloading IRP patients were significantly higher than those of non-iron overloading IRP and normal controls.</p><p><b>CONCLUSION</b>Mechanisms underlying bone marrow damage by iron overload might be through the follows: ①The increased ROS induced by excessive iron deposition affected the expressions of Caspase-3 and Bcl-2, which caused more BMMNC apoptosis; ②The abnormal number and ratio of T lymphocytes caused by iron overload aggravated the abnormality of immunity of IRP; ③Iron overload may increase the damage to erythrocytes and stem cells coated with auto-antibodies.</p>

ABSTRACT

OBJECTIVES: The spontaneous spinal epidural hematoma (SSEH) is a rare clinical entity. Patients typically present with sudden onset back pain followed by neurological deficits. METHODS: Diagnosis of SSEH is usually made with MRI and standard treatment is surgical evacuation. In 1996, Groen published the most comprehensive review on the SSEH in which he analyzed 333 cases. We review 104 cases of SSEH presented in the English literature since the last major review and add three of our own cases, for a total of 107 cases. RESULTS: Our patients presented with back pain and neurologic deficits. Two made excellent functional recovery with prompt surgical decompression while one continued to have significant deficits despite evacuation. Better postoperative outcome was associated with less initial neurological dysfunction, shorter time to operation from symptom onset and male patients. CONCLUSION: We discuss the etiology of SSEH and report current trends in diagnosis, treatment, and outcome.

ABSTRACT

Objective To evaluate percutaneous endoscopic gastrostomy (PEG) for long-term enteral nutrition in patients with cancers of head and neck. Methods PEGs were performed for 12 patients with head and neck cancers, the indication for which included serious buccal mucositis, difficulty in swallowing, anorexia, and obstruction of the digestive tract. Before PEG and 8 weeks after PEG, serum concentrations of total protein and albumin of the patients were measured, body composition including body weight, free fat mass, and fat mass were measured by bioelectric impedance analysis (BIA), and Karnofsky performance score ( KPS) was evaluated. Results After enteral nutrition for 8 weeks through PEG, the serum concentrations of total protein and albumin of the patients increased significantly (63.8?0.3g/L vs 57.4?0.2g/L, P
