Comparison between pathology and computer for quantitative determination of femoral head necrosis / 中国骨伤

OBJECTIVE@#To compare computer measurement semi automatic quantitative detection software system with ultra thin layer pathological section to confirm the avascular necrosis percentage of the femoral head, and provide reference for clinical treatment options.@*METHODS@#From June 2012 to December 2013, the X-ray and MRI of 24 patients(24 hips on unilateral) were reviewed, who had avascular necrosis of the femoral head at late stage (stage III and IV) according to the ARCO international staging system, and performed by total hip arthroplasty. There were 15 males and 9 females, with an average age of (65.1±8.8) years old ranging 33 to 74 years old. Based on imaging system combined with computer aided technology(CAD) system and postoperative ultrathin slice, the volume of the area of femoral head necrosis were calculated. Then combining with the total volume of the femoral head was calculated by X-ray, the percentage of each femoral head necrosis area was calculated as a percentage of the whole ball head in both methods.@*RESULTS@#For 24 hips, the normal femoral head volume was (39.58±3.29) cm³ on average of X-ray film, the necrotic volume was (20.00±3.04) cm³ on average of MRI by the calculation of computer. The necrotic volume occupying in the volume of the normal femoral head was (42.92±6.09)% on average ranged. The necrotic lesion size was larger than 40% in 16 hips, 30% to 40% in 8 hips, 1 ess than 30% in 0 hip. Under the pathological section, the necrosis volume was (19.89±3.17) cm³, the necrotic volume occupying in the volume of the normal femoral head was (40.33±6.36)%. The necrotic lesion size was larger than 40% in 12 hips, 30% to 40% in 11 hips, 1 ess than 30% in 1 hip. In computer and general measurement, the two entire femoral head volume difference was (0.113±0.466) cm³, there was no significant difference using these measurements(=-1.186, =0.248). After the linear correlation statistics analysis, there was a positive correlation relationship in necrotic volume between computer software and pathology measurement(γ=0.980, =0.000).@*CONCLUSIONS@#The severity of the necrotic femoral head is closely related to the percentage of necrotic area. When the ratio of necrotic lesions and the whole femoral head is greater than 30%, the patients' clinical symptoms tend to aggravate, the probability of total hip arthroplasty increased significantly. It have great significances in femoral head necrosis installment, judge the prognosis, guide the selection of treatment and monitoring curative effect.

A comparative study on the measurement of femoral head necrosis lesions using ultra-thin layer slicing and computer aided identification / 中国骨伤

<p><b>OBJECTIVE</b>To compare the differences between computer aided identification and ultra-thin layer slicing in measuring the lesions of femoral head necrosis,and to confirm the accuracy and practicability of computer aided method.</p><p><b>METHODS</b>From June 2012 to December 2013, the X-ray and MRI of 24 patients (24 hips on unilateral) were reviewed, who had avascular necrosis of the femoral head (ANFA) at late stage (stage III and IV) according to the ARCO international staging system. There were 15 males and 9 females, with an average age of (65.1 ± 8.8) years old, ranged 33 to 74 years old. Based on the software system with seeds point identification, the ragional adaptive search method with computer aid was used to calculate the volume of necrotic lesion in femoral on MRI. Then the pathological slices of those intraoperative femoral heads were made to measure the gross volume of necrotic lesion in femoral head,and the values were compared with the data in the computer.</p><p><b>RESULTS</b>For 24 hips, by the calculation of computer, the necrotic volume was (20.00 ± 3.04) cm (ranged, 18.72 to 21.29 cm³). Under the pathological section, the necrotic volume of the femoral head was (19.89 ± 3.17) cm³ (ranged, 18.55 to 21.23 cm³). In computer and pathology two kinds of measurement, the two entire femoral head volume had no significant difference using these two measurements (t = -1.227, P = 0.232).</p><p><b>CONCLUSION</b>Computer aided identification for necrotic area of femoral head adaptive can demonstrate the morphology of femoral head necrosis accurately and reliably, which will help surgeon better understand the morphology and orientation in femoral head.</p>

Progress on treatment of transverse patella fractures with tension band fixation / 中国骨伤

Transverse fracture is the most common in patella fracture and tension band fixation is one of the most effective methods. Surgical wire tension band technique is simple, the use of materials is also simple, but it is not strong and difficult to promote. Kirschner tension band technique can get satisfactory reduction with reliable fixation, but it is easy to complicate with steel wire breakage and Kirschner loosening. Screw tension band technique inherits the traditional advantages of simple manipulation and reliable fixation, also overcomes the disadvantages of early activity limitations caused soft tissue irritation of tension band around knee, the slippage and breakage of internal fixation, and the technique can be popularized generally.

Annlication of external fixator combined with damage control treatment for open fracture of the extremities / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the application and effects of external fixator under the guidance of damage control therapy in limb open fracture.</p><p><b>METHODS</b>From May 2008 to January 2013,72 cases with severe limb open fractures (Unincor- porated shock) were divided into control group and observation group (36 cases in each group). In observation group, 36 patients (including 22 males and 14 females) were treated by external fixator at stage I, as soon as possible after waiting for patients physiology conditions being stable,the stage II fracture operation was performed. In control group, 36 patients (24 males and 12 females) were treated by the first stage open reduction. The hospital admission time, open fracture severity score (OFSS),operation duration,operative blood loss,X-ray expose times, callus appear time, fracture healing time, postoperative infection rate, complications and Johner-Wruhs accceccment were recorded and evaluated.</p><p><b>RESULTS</b>All patients were followed up for 8 to 12 months (10.4 in averaged). The mean operation duration, operative blood loss, callus appear time, fracture healing time the mean operation duration reespectively were (56.79±8.87) min, (216.16±18.21) ml, (5.32±0.71) weeks, (12.79±2.52) weeks in observation group,and (104.53±9.28) min, (439.93±14.65) ml, (4.97±1.26) weeks, (14.81±2.63) weeks in control group. According to Johner-Wruhs acccecement,there were were 33 cases in excellent,2 in good,and 1 in poor in observation group,non-union of fracture in 1 case,local infection occurred in 1 cases; in control group 25 cases in excellent,6 in good, and 5 in poor, non-union of fracture in 1 case,local infection occurred in 8 cases. There were significant differences in operation duration, operative blood loss, callus appear time, fracture healing time, postoperative infection rate, complications (P<0.05). There were no significant differences in hospital admission time, open fracture severity score and X-ray expose times (P>0.05).</p><p><b>CONCLUSION</b>Under the guidance of damage control therapy,using external fixator measures to treat patients with open fractures of limbs is worth popularizing in clinical application because it can shorten the operation time, less blood loss, reduce the infection rate and complications, improve the success rate of surgery and recovery rate.</p>

Progress on peri-operative hidden blood loss after hip fracture / 中国骨伤

Hip fracture patients preoperative and postoperative exist hidden blood loss which often affect patients' wound healing, increase the probability of infection, prolong rehabilitation exercise, influence postoperative effect. At the same time, the body's blood loss increase the activation of the blood clotting mechanism, promote the incidence of deep vein thrombosis, bleeding and deep vein thrombosis has become the main causes of high risk in hip operation. It is very important to stop bleeding, anticoagulation should not be ignored, so how to effectively deal with the prominent contradiction between the postoperative anticoagulation and bleeding or looking for a best balance has become a intractable problems in hip fracture treatment.
