1/10. The effect of hallux valgus correction on chronic plantar ulceration. A case report.Plantar pressure-measurement technology may provide the clinician with valuable objective information for monitoring the effects of therapeutic intervention on the foot. The use of this technology is described in the preoperative and postoperative assessment of a patient undergoing hallux valgus surgery for the treatment of a chronic neuropathic skin ulcer over the medioplantar aspect of her first metatarsophalangeal joint.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/10. Paramalleolar bypass concomitantly with extended endarterectomy for limb-threatening ischemia: A case report.A 74-year-old male was admitted to our university hospital with a refractory ulcer of the left third toe. The ankle pressure index was 0.43. On his angiogram, the popliteal artery was totally occluded in the distal site, while the peroneal artery was solely patent and inflowed into the distal posterior tibial artery. At surgery, endarterectomy of 7 cm in length was performed on the tibioperoneal trunk of the occluded popliteal artery following patch repair using a saphenous vein to restore the genicular arterial network and infrapopliteal arteries. Thereafter, the bypass surgery was performed using the in situ saphenous vein from the patent proximal popliteal artery to the distal posterior tibial artery. The postoperative angiogram showed patency of the graft as well as restoration of the genicular arterial network and infrapopliteal arteries. The ankle pressure index improved to 1.04, and the refractory ulcer was completely cured one month after revascularization.- - - - - - - - - - ranking = 2keywords = pressure (Clic here for more details about this article) |
3/10. A new ambulatory foot pressure device for patients with sensory impairment. A system for continuous measurement of plantar pressure and a feed-back alarm.Abnormal and excessive plantar pressure is a major risk factor for the development of foot ulcers in patients with loss of protective pain sensation. Repeated pressure with each step can result in inflammation at specific points, followed by ulcer formation. patients with peripheral nerve disease are unable to prevent the development of such lesions, which often lead to amputation. For this reason, it has been suggested that a fundamental therapeutic intervention should be the reduction of high plantar pressure. We have developed a portable, battery-operated ambulatory foot pressure device (AFPD) which has two important functions: (1) to determine the areas of high plantar pressure, and (2) to provide an acoustic alarm, adjusted to a specific pressure load, which is triggered when weight-bearing exceeds the predetermined plantar pressure. A memory of plantar pressure parameters allows for downloading of the data and sequential analysis during the investigation period. Such an alarm device could replace the lack of pain sensation and may play an important role in the prevention of ulcer development and lower extremity amputation.- - - - - - - - - - ranking = 16keywords = pressure (Clic here for more details about this article) |
4/10. Revascularization of femoropopliteal artery occlusion in Werner's syndrome. Report of a case and review of surgical literature in cardiovascular lesions.A patient with Werner's syndrome suffering from a chronic ulcer on the right ankle joint underwent femoropopliteal bypass and patch angioplasty combined with endarterectomy of the distal popliteal artery. Postoperative angiography showed satisfactory graft patency and distal run-off, and the ulcer improved. Femoropopliteal occlusive disease in Werner's syndrome tends to have poor run-off and the internal diameter of the popliteal artery with diffuse arteriosclerotic lesion is often too small to facilitate distal anastomosis. Therefore, a conventional bypass procedure is not always effective and an aggressive attitude is essential to obtain sufficient ankle blood pressure and improve the leg ulcer in Werner' syndrome.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
5/10. Ulcerating plantar keratoderma in association with systemic lupus erythematosus.This report highlights the finding of ulcerative plantar keratoderma in two patients with systemic lupus erythematosus (SLE). Both patients suffered from painful plantar ulcerations and fissures; in one patient there was diffuse desquamation over the entire plantar surface, while the other patient's lesions were focal and accentuated over weight-bearing surfaces. Other etiologies for keratoderma including papulosquamoua disease, contact dermatitis, tinea and primary keratodermas were excluded. Both patients were resistant to multiple topical therapies including super-potent topical corticosteroids, vitamin d analogues and retinoids, but did report moderate relief with hydrocolloid dressings applied over super-potent topical corticosteroids and pressure off-loading measures. Lupus-associated keratoderma can be recurrent and recalcitrant to treatment, often necessitating aggressive therapy and particular attention to advanced wound care methodologies. While not a specific cutaneous sign of lupus, it should be recognized as a cause for considerable morbidity.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
6/10. The vacuum assisted closure of complex wounds: report of 3 cases.Treatment of wounds using conventional methods is frequently limited by inadequate local wound conditions, or by a poor systemic clinical situation. vacuum system may promote faster granulation tissue formation, remove excessive exudate, increase blood flow in the wound, and attract the borders of the wound to the center, reducing its dimension. We present 3 cases of patients with difficult wounds, due to bad local conditions, or poor clinical situation, in whom we used a vacuum system to prepare the wound for the surgical closure. One patient had a pressure ulcer, another had a diabetic foot ulcer, and the third one had an open foot stump. In the 3 cases a significant improvement of the wound conditions was achieved after 7 to 8 days, allowing successful surgical treatment with flap or skin grafts.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
7/10. Verrucous carcinoma of the foot from chronic pressure ulcer.STUDY DESIGN: This is a case report with literature review. OBJECTIVE: To describe a case of verrucous carcinoma, a rare histopathologic type, complicating a chronic pressure ulcer of duration less than 3 years. SETTING: The department of Physical medicine and rehabilitation, University of north carolina at Chapel Hill, USA. METHOD: A 24-year-old African-American male with long-standing incomplete paraplegia visited the wound clinic due to a pressure ulcer that had lasted for more than 1 year on the medial side of the right foot. Despite conservative management for almost 2 years after the initial visit, the ulcer is suspected to have undergone malignant transformation. Histological study led to the diagnosis of verrucous carcinoma that necessitated transtibial amputation on the right foot. RESULT: The carcinoma developed within 3 years, which was a relatively short time period for a pressure ulcer to have undergone malignant transformation. The diagnosis of verrucous carcinoma has never been reported as carcinoma complicating a pressure ulcer. No evidence of local recurrence or distant metastasis was seen in postoperative 10 months. CONCLUSION: The possibility of malignant transformation should be kept in mind in cases of pressure ulcers that are unresponsive to treatment or that show morphological changes suspected to be cancerous. Furthermore, early detection and intervention increases the probability for successful outcome.- - - - - - - - - - ranking = 9keywords = pressure (Clic here for more details about this article) |
8/10. Change of weight-bearing pattern before and after plantar reconstruction with free anterolateral thigh flap.We reconstructed a large-sized defect at the weight-bearing plantar region by a free anterolateral thigh flap successfully. This is the first case report of using the anterolateral thigh flap for reconstruction of the plantar foot. Based on the preoperative and postoperative pedogram examinations, the pressure distribution on the weight-bearing area reconstructed by the transferred flap was obviously improved and demonstrated a nearly normal pattern. No previous report has compared the weight-bearing pattern before and after large plantar reconstruction with a free flap. The anterolateral thigh free flap, which provides adequate bulk and contour of the foot, and which withstands weight pressure and shearing force and has the ability to provide recovery of sensation, is considered a good alternative in covering a large weight-bearing plantar defect.- - - - - - - - - - ranking = 2keywords = pressure (Clic here for more details about this article) |
9/10. Can peripheral nerve blocks contribute to heel ulcers following total knee replacement?Peripheral nerve blocks are widely used for postoperative analgesia following total knee replacement. We would like to present three cases of heel ulcers encountered following a peripheral nerve block for knee replacement surgery. Postoperative heel ulcers have resulted in delayed rehabilitation in all three patients. attention needs to be given to the pressure points in the foot after the nerve blocks. awareness of this uncommon complication is necessary to prevent its occurrence.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
10/10. Severe peripheral neuropathy and elevated plantar pressures causing foot ulceration in pituitary gigantism.We report two patients with treated pituitary gigantism and peripheral neuropathy, one of whom has chronic foot ulceration. Detailed neurophysiological assessment was performed on both patients. The patient with foot ulceration had clinical and neurophysiological evidence of severe neuropathy, whereas the patient without ulceration had only neurophysiological abnormalities. The sweating response to acetylcholine was markedly impaired in the feet of both patients, suggesting pedal autonomic denervation. Neither patient had evidence of diabetes mellitus and detailed investigation failed to reveal an alternative cause of peripheral neuropathy. Optical pedobarography revealed abnormally high pressure (> 10 kg/cm2) under the metatarsal heads of both patients, one such area coinciding with the area of ulceration. Thus in pituitary gigantism elevated plantar pressures may contribute to the development of foot ulceration when severe peripheral neuropathy is present. Furthermore, as in diabetes mellitus, impaired sweating may also increase the risk of ulceration as the resultant dry skin may develop fissures.- - - - - - - - - - ranking = 6keywords = pressure (Clic here for more details about this article) |
