Trochanteric Femur Fractures: Application of Skeletal Traction during Surgery Does Not Alter Soft-Tissue Microcirculation

Background and Objectives: Wound infections provoked by alterations in microcirculation are major complications in the treatment of trochanteric femur fractures. Surgical fracture fixation on a traction table is the gold standard for treatment, but the effect on tissue microcirculation is unknown. Microcirculation could be impaired by the pull on the soft-tissue or by a release of vasoactive factors. We hypothesized that intraoperative traction impairs soft-tissue microcirculation. Materials and Methods: In 22 patients (14 women, eight men), average age 78 years (range 36–96 ± 14), with trochanteric femur fractures, non-invasive laser-Doppler spectrophotometry was used to assess oxygen saturation, hemoglobin content, and blood flow in the skin and subcutaneous tissue before and after application of traction. Measurements were recorded in nine locations around the greater trochanter at a depth of 2, 8, and 15 mm before and after fracture reduction by traction. Results: No differences were found in any depth with traction compared to without (oxygen saturation: p = 0.751, p = 0.308, and p = 0.955, haemoglobin content: p = 0.651, p = 0.928, and p = 0.926, blood flow: p = 0.829, p = 0.866, and p = 0.411). Conclusion: In this pilot study, the application of traction does not affect skin and subcutaneous microcirculation in the surgery of proximal femur fractures.

Background: Cysticercosis in humans is infection with the larval form (cysticercus cellulosae) of the pork tapeworm T. solium. Encystment of larvae can occur in almost any tissue. The location of cysts in order of frequency is the central nervous system, subcutaneous tissue and striated muscle, vitreous humour of the eye and, rarely, other tissues. High resolution ultrasound can be used in the diagnosis of muscular and soft tissue cysticercosis. Objective: The aim of this study is to evaluate the ultrasonographic findings in cases of muscular and soft tissue cysticercosis. Materials and methods: It was a retrospective review of the cases of muscular and soft tissue cysticercosis which were diagnosed by ultrasound during June 2007 to May 2009 in the department of Radiology and Imaging, Nepalgunj Medical College Teaching Hospital. A total of six patients were evaluated. Result: There were four males and two females. Age of the patient ranged from 18 to 50 years. All of the patients presented with a swelling with pain in five of them. There was a wide variation in the location of the cysts. In all cases ultrasound revealed a cystic lesion with an echogenic eccentric pedunculated nodule attached to the wall. The mean diameter of the cyst was 6mm. Smooth wall was present in five cases whereas one of the cysts revealed irregular wall. Pericystic inflammatory changes were seen in the adjacent muscles. Conclusion: Ultrasound is a safe and non-invasive method that can be used in the diagnosis of muscular and soft tissue cysticercosis. Key words: Muscular and soft tissue cysticercosis; ultrasound.

The blood supply to the central third of the Achilles tendon was studied in adult rabbits using the hydrogen washout technique before and after soft tissue dissection including paratenon. The soft tissue dissection caused a decrease of the blood flow rate in the Achilles tendon by approximately 35 per cent. These results may indicate that the central third of the tendon with a paratenon receives its blood supply from the extrinsic vascular system by approximately 35 per cent and from the intrinsic vascular system by approximately 65 per cent.

Using 133Xe-DSPECT, measurements of regional cerebral blood flow (rCBF) were performed before and after stimulation with 1 g of Diamox® in 55 patients with symptomatic occlusion of the internal carotid artery (ICA) and 26 patients without evidence of brain disease (normals). In normals, a negative correlation (r = -0,74) of the Diamox-induced increase of hemispheric blood flow (reserve capacity) and rCBF at rest was observed. In 48 of the 55 patients (87%) with ICA-occlusion a reduced reserve capacity was found. The extent of reduction, however, did not correlate with the findings of transmission CT, because 15 of 21 patients (71 %) with normal CT-scans presented a moderate to severe reduction of reserve capacity. In contrast, reserve capacity corresponded to the extent of arterial collateralisation as documented by cerebral panangiography. In 31 patients EC/IC-bypass surgery was performed. In follow-up studies reserve capacity increased, especially in patients who had a severe reduction preoperatively. Therefore, the combined measurement of rCBF at rest and of reserve capacity is a sensitive, non-invasive method for the diagnosis of (even bilateral) cerebrovascular disease and can be helpful to identify patients with hemodynamic ischemia, who may benefit from EC/IC-bypass surgery.

Reperfused Myocardium

Objective Hypothermia is known to limit the extent of myocardial infarction. The earlier hypothermia is applied to an ischemic myocardium, the more tissue can be salvaged. Topical negative pressure (TNP) is known to increase blood flow and stimulate angiogenesis in subcutaneous tissue and skeletal muscle. We have previously shown that a myocardial TNP of −50 mm Hg significantly increases microvascular blood flow in the underlying myocardium in ischemic and reperfused porcine myocardium. The present study was designed to elucidate the effect of different TNP levels on microvascular blood flow in reperfused myocardium during hypothermia. Methods Seven pigs underwent median sternotomy. The microvascular blood flow in the myocardium was recorded before and after the application of −50, −75, −100, −125, and −150 mm Hg using laser Doppler velocimetry. Analysis was performed in the epicardium and at a depth of 6 to 8 mm in the myocardium after 40 minutes of occlusion of the left anterior descending artery followed by cooling to 31°C, and reperfusion for another 20 minutes. Results A TNP of −50 mm Hg significantly increased blood the flow in the epicardium, from 116.7 ± 10.0 PU to 244.5 ± 52.6 PU (*P < 0.05) at 31°C. A TNP of −50 mm Hg significantly increased microvascular blood flow in the myocardium, from 155.0 ± 8.4 PU to 236.7 ± 61.5 PU (*P < 0.05). Conclusions Only a TNP of −50 mm Hg, applied over the left anterior descending artery region in reperfused hypothermic myocardium significantly increased the microvascular blood flow in the epicardium and in the myocardium.

Far Infrared Radiation

The most frequent clinical complication is diabetes. Diabetes is characterized by elevated blood glucose levels resulting in sensory nerve damage or lesions. Diabetic foot wounds are often slow to heal and require medical attention and monitoring. This study evaluates the effect of far-infrared radiation on the microcirculation and plantar pressure in the diabetic foot. Ten diabetics and 4 nondiabetics were recruited in this study. The diabetic group was examined before and after the intervention in each month for 3 consecutive months. Four nondiabetic groups were also measured before and after the intervention for 2 weeks in each month. The surface temperature and blood flow in the diabetic foot was significantly improved (temperature: 32.1 ± 2.3°C vs 33.5 ± 2.2°C, P < .05; blood flow image: 118.3 ± 58.1 PU [perfusion unit] vs 50.4 ± 4.3 PU, P < .05). The sympathetic nerve activity index LF also increased from 40.8 ± 18.6% to 61.8 ± 13.5% ( P = .07) in the second month. Plantar pressure tended to increase in the third month. This might indicate that far-infrared radiation could affect the mechanical properties of the plantar foot soft tissue. These results indicated that the effects of far-infrared radiation would improve blood circulation and change the soft tissue properties in the diabetic foot.

Introduction. Simultaneous correction of severe deformities of the feet may be accompanied by a negative effect on the trophism of the adjacent soft tissues. However, the literature does not pay enough attention to the analysis of the blood supply to soft-tissue structures in the field of surgical intervention in the correction of complex deformities of the feet. The aim of the study is to investigate condition of soft tissues blood supply in the area of surgery before and after simultaneous correction of severe feet deformities by triple arthrodesis in patients with cerebral palsy.Material and methods. The article is based on the results of study of 21 cerebral palsy patients with multicomponent feet deformities. All patients underwent simultaneous correction of foot deformities with usage of internal fixation. Patients were examined for the soft tissues blood supply (skin, subcutaneous fat, muscles) in the area of surgery using laser and high-frequency Doppler flowmetry before and after performing all phases of foot surgery.Results. Capillary skin blood flow after performing all stages of operation, removing tourniquet and suturing tended to increase in all areas of measurement, but significantly increased on the dorsum of the foot, at points 1 (by 53.3 %, p <0.05), 4 (by 69.0 %, p<0.05), and at point 6 (53.9 %, p <0.05). Indicators of blood flow of subcutaneous fat and muscle tissue after performing all stages of operation and removal of tourniquet did not significantly differ from the preoperative level. In the long-term follow-up period, all examined patients showed good clinical results in 81 % of cases, satisfactory – in 19 % of patients who noted periodic moderate pain in the feet after a long walk. There were no unsatisfactory results.Conclusion. After simultaneous intraoperative correction of severe feet deformities by triple arthrodesis in the area of operative wound in patients with cerebral palsy, there is no decrease in the microcirculatory blood flow in soft tissuesin the surgical intervention area. There is either stabilization or an increase in the perfusion of these structures.
