RESUMO

BACKGROUND: Various surgical management methods have been proposed for ischial sore reconstruction, yet it has the highest recurrence rate of all pressure ulcer types. A novel approach combining the advantages of a perforator-based fasciocutaneous flap and a muscle flap is expected to resolve the disadvantages of previously introduced surgical methods. METHODS: Fifteen patients with ischial pressure ulcers with chronic osteomyelitis or bursitis, who underwent reconstructive procedures with an inferior gluteal artery perforator (IGAP) fasciocutaneous flap and a split inferior gluteus maximus muscle flap from January 2011 to June 2016, were analyzed retrospectively. The split muscle flap was rotated to obliterate the deep ischial defect, managing the osteomyelitis or bursitis, and the IGAP fasciocutaneous flap was rotated or advanced to cover the superficial layer. The patients’ age, sex, presence of bursitis or osteomyelitis, surgical details, complications, follow-up period, and ischial sore recurrence were reviewed. RESULTS: All ischial pressure ulcers were successfully reconstructed without any flap loss. The mean duration of follow-up was 12.9 months (range, 3–35 months). Of 15 patients, one had a recurrent ulcer 10 months postoperatively, which was repaired by re-advancing the previously elevated fasciocutaneous flap. CONCLUSIONS: The dual-flap procedure with an IGAP fasciocutaneous flap and split inferior gluteus maximus muscle flap for ischial pressure ulcer reconstruction is a useful method that combines the useful characteristics of perforator and muscle flaps, providing thick dual padding with sufficient vascularization while minimizing donor morbidity and vascular pedicle injury.

RESUMO

Los osteocondromas constituyen el grupo de tumores óseos benignos más frecuentes en cadera, solitarios o como parte de una enfermedad exostosante múltiple; pueden ser asintomáticos o sintomáticos. Se tratan para evitar el riesgo de una degeneración sarcomatosa relativamente frecuente en este sitio. El propósito del estudio es revisar la entidad a partir de experiencia hospitalaria con énfasis en las manifestaciones clínicas y tratamiento. Se reporta el caso de un paciente masculino de 22 años e historia de hemofilia, que presentó una tumoración ósea a nivel de cadera derecha que los limita rangos de movilidad


Osteochondromas constitute the group of benign bone tumors most frequent in the hip, solitary or as part of a multiple exostosante disease; They can be asymptomatic or symptomatic. They are treated to avoid the risk of a relatively frequent sarcomatous degeneration at this site. The purpose of the study is to review the entity based on hospital experience with emphasis on clinical manifestations and treatment. The case of a 22-year-old male patient and a history of hemophilia is reported, who presented a bone tumor at the right hip level that limits mobility ranges.

RESUMO

PURPOSE: Ischiofemoral impingement (IFI)-primarily diagnosed by magnetic resonance imaging (MRI)-is an easily overlooked disease due to its low incidence. The purpose of this study was to evaluate the usefulness of false profile view as a screening test for IFI. MATERIALS AND METHODS: Fifty-eight patients diagnosed with IFI between June 2013 and July 2017 were enrolled in this retrospective study. A control group (n=58) with matching propensity scores (age, gender, and body mass index) were also included. Ischiofemoral space (IFS) was measured as the shortest distance between the lateral cortex of the ischium and the medial cortex of lesser trochanter in weight bearing hip anteroposterior (AP) view and false profile view. MRI was used to measure IFS and quadratus femoris space (QFS). The receiver operating characteristics (ROC), area under the ROC curve (AUC) and cutoff point of the IFS were measured by false profile images, and the correlation between the IFS and QFS was analyzed using the MRI scans. RESULTS: In the false profile view and hip AP view, patients with IFI had significantly decreased IFS (P < 0.01). In the false profile view, ROC AUC (0.967) was higher than in the hip AP view (0.841). Cutoff value for differential diagnosis of IFI in the false profile view was 10.3 mm (sensitivity, 88.2%; specificity, 88.4%). IFS correlated with IFS (r=0.744) QFS (0.740) in MRI and IFS (0.621) in hip AP view (P < 0.01). CONCLUSION: IFS on false profile view can be used as a screening tool for potential IFI.

RESUMO

PURPOSE: This study was performed to evaluate long-term clinical and radiologic outcomes of cemented total hip arthroplasty in patients with ankylosing spondylitis. MATERIALS AND METHODS: A retrospective study of 12 patients (16 cases) diagnosed with ankylosing spondylitis undergoing total hip arthroplasty with cemented femoral stem from November 2002 to January 2006 with a minimum follow up of 10 years. Clinical outcomes were assessed using Harris Hip Scores and measures of pain and range of motion. Radiologic outcomes were assessed with serial plain X-ray. Fixation and stability of implant, enthesopathy of ischium and development of heterotopic ossification were also evaluated. RESULTS: Mean Harris Hip Scores significantly improved from pre-operative levels (58 points; range, 39–81 points) to post-operative (92 points; range, 68–100 points). Mean flexion contracture levels decreased from preoperative (13°) to post-operative (5°), and mean post-operative range of motion improved 106° compared to preoperative levels. No newly developed osteolysis lesions or implant loosening were observed in last follow up X-rays. One heterotopic ossification and one greater trochanter fracture were observed. Greater trochanter fracture was treated conservatively, and was resulted in bony union. No patients underwent revisions. CONCLUSION: This study revealed positive long-term clinical and radiologic outcomes following total hip arthroplasty with cemented femoral stems in patients with ankylosing spondylitis patients.

RESUMO

Local flaps exhibit excellent color matching that no other type of flap can compete with. Moreover, surgery using a local flap is easier and faster than surgery using a distant or free flap. However, local flaps can be much more difficult to design. We designed 2 templates to plan a V-Y rotation advancement flap. The template for a unilateral V-Y rotation advancement flap was used on the face (n=5), anterior tibia (n=1), posterior axilla (n=1), ischium (n=1), and trochanter (n=2). The template for a bilateral flap was used on the sacrum (n=8), arm (n=1), and anterior tibia (n=1). The causes of the defects were meningocele (n=3), a decubitus ulcer (n=5), pilonidal sinus (n=3), and skin tumor excision (n=10). The meningocele patients were younger than 8 days. The mean age of the adult patients was 50.4 years (range, 19–80 years). All the donor areas of the flaps were closed primarily. None of the patients experienced wound dehiscence or partial/total flap necrosis. The templates guided surgeons regarding the length and the placement of the incision for a V-Y rotation advancement flap according to the size of the wound. In addition, they could be used for the training of residents.

RESUMO

OBJECTIVE: To identify the pressure relieving effect of adding a pelvic well pad, a firm pad that is cut in the ischial area, to a wheelchair cushion on the ischium. METHODS: Medical records of 77 individuals with SCI, who underwent interface pressure mapping of the buttock-thigh area, were retrospectively reviewed. The pelvic well pad is a 2.5-cm thick firm pad and has a cut in the ischial area. Expecting additional pressure relief, it can be inserted under a wheelchair cushion. Subjects underwent interface pressure mapping in the subject's wheelchair utilizing the subject's pre-existing pressure relieving cushion and subsequently on a combination of a pelvic well pad and the cushion. The average pressure, peak pressure, and contact area of the buttock-thigh were evaluated. RESULTS: Adding a pelvic well pad, under the pressure relieving cushion, resulted in a decrease in the average and peak pressures and increase in the contact area of the buttock-thigh area when compared with applying only pressure relieving cushions (p < 0.05). The mean of the average pressure decreased from 46.10±10.26 to 44.09±9.92 mmHg and peak pressure decreased from 155.03±48.02 to 131.42±45.86 mmHg when adding a pelvic well pad. The mean of the contact area increased from 1,136.44±262.46 to 1,216.99±255.29 cm². CONCLUSION: When a pelvic well pad was applied, in addition to a pre-existing pressure relieving cushion, the average and peak pressures of the buttock-thigh area decreased and the contact area increased. These results suggest that adding a pelvic well pad to wheelchair cushion may be effective in preventing a pressure ulcer of the buttock area.

RESUMO

The incidence of avulsion fracture of ischial tuberosity is reported to present in 1.4%–4% of hamstring injuries. The injury mechanism is known to be caused by a sudden forceful hip flexion in the extended knee with eccentric load to the hamstrings. Although the majority of hamstring injuries are strains of the muscle, avulsion fracture of ischial tuberosity occurs rarely. In this report, a 13-year-old boy with avulsion fracture of ischial tuberosity is presented. Successful clinical outcome was achieved with careful conservative management. Previous literatures including operative indications are reviewed.

RESUMO

PURPOSE: We hypothesized that the central dislocation of the femoral head does generally not occur in transverse acetabular fractures, although it does usually occur in both column fractures. MATERIALS AND METHODS: Fifty-two transverse and both column acetabular fracture cases were evaluated retrospectively. The distances between (a) the sciatic notch on the fracture side and the vertical axis of the pelvis (VA line) and (b) the contralateral intact sciatic notch and the VA line were measured. The a/b ratio corresponded to the superior iliac segment displacement or rotation. The ratio of the distance between the fracture side femoral head and the VA line (c) and the distance between the contralateral intact femoral head and the VA line (d) corresponded to the femoral head displacement. The width of ischium (e) on fractured side and (f) contralateral side were measured. The e/f ratio increment reflected ischiadic fragment mobility. RESULTS: The median value of femoral head displacement (c/d) of the transverse fracture group (n=25) was 1.02 (1.000-1.07). Ischiadic fragment rotation (e/f ratio) of the transverse fracture group was 1.000. The median value of femoral head displacement (c/d) of the both column fractures (n=27) was 0.78 (0.64-0.85). Ischiadic fragment rotation (e/f ratio) of the both-column group was 1.15 (1.06-1.23). The differences between groups according to measurements were statistically significant. CONCLUSION: In contrary to Letournel description, our findings showed no medialization of femoral head in transverse acetabular fractures in general. This might be an illusion resulting from external rotation of the superior iliac segment.

RESUMO

Aneurysmal bone cyst [ABC] is a locally destructive lesion of the bone rather than a true neoplasm. The pelvis is not an unusual site for an ABC; approximately 12% of cases occur in this location. We present a case of aneurysmal bone cyst [ABC] in ischiopubic ramus in a 22 years old male who presented with right inguinal swelling and pain. He was evaluated with X-ray and Magnetic Resonance Imaging MRI of pelvis. A review of literature regarding this rare site of ABC with radiological features is also described in this case report. ABC of ischiopubic ramus is an uncommon entity hence diagnosis of such a case requires proper clinical, radiological and histopathological evaluation to rule out other differential diagnoses of an expansile, osteolytic lesion. This will help in selecting a proper treatment plan

RESUMO

Las úlceras por presión son las complicaciones secundarias más comunes a una lesión medular, las cuales ponen en riesgo tanto la salud como la vida de quienes las padecen. Las úlceras por presión más comunes en lesionados medulares aparecen en la región pélvica, principalmente en las tuberosidades isquiáticas (TI's). Una estrategia usada en la clínica es medir la presión generada entre el paciente y la superficie donde se encuentra para evaluar el riesgo que representa dicha superficie para el desarrollo de úlceras por presión sin embargo, este tipo de mediciones superficiales no garantizan que la presión en los tejidos internos subyacentes a prominencias óseas sea inocua. Con el fin de estudiar los mecanismos de formación de úlceras por presión, se realizó el análisis de un modelo de pelvis y tejido subyacente por medio del Método de los Elementos Finitos (MEF). De esta manera se puede estudiar el comportamiento de las TI's sobre su tejido circundante, así como analizar los efectos biomecánicos que provocan las úlceras. Se construyó el modelo computacional por medio de un software de CAD (Computing Aided Design) de la pelvis a partir de cortes tomográficos. El modelo fue exportado al software COMSOL y se analizaron seis casos de estudio: un análisis de la pelvis sobre bloques de tejido sano y cinco casos más, los cuales simulan lesiones en el tejido con distintas profundidades, representando úlceras superficiales e internas. Los resultados mostraron que los puntos de máximo esfuerzo, en todas las pruebas, se localizan justo debajo de la TIs además se encontró que las lesiones internas presentan mayores esfuerzos y deformaciones, los cuales pueden ser precursores de daño en el tejido.


Pressure ulcers are the most common secondary complication to a spinal cord injury, which endanger both health and life of the patients who suffer them. The most common pressure ulcers in spinal cord injuries occur in the pelvic region, mainly in the ischial tuberosities (ITs). A strategy used in clinic is to quantify the pressure generated between the patient and the surface, in order to assess the risk posed by that surface for developing pressure ulcers. Despite this, this type of surface measurements does not guarantee that pressure in the internal tissues underlying to bony prominences, to be safe. In order to study the mechanisms of formation of pressure ulcers, an analysis of a model of the pelvis and its underlying tissue was performed using the Finite Element Method (FEM). By this means we can study the behavior of ITs on its surrounding tissue, and at the same time, we analyze the biomechanical effects those cause ulcers. The computational model of the pelvis was built from tomographic slices using CAD software (Computing Aided Design). The model was exported to the finite element software COMSOL and six study cases were analyzed: an analysis of the pelvis on healthy tissue blocks and five more cases, which simulate tissue injury with different depths, representing surface and internal ulcers. The results showed that the maximum stress points in all tests are located just below the ITs it was also found that internal injuries present higher stresses and strains, which can be precursors of tissue damage.

RESUMO

INTRODUCTION: Distant metastases of mucoepidermoid carcinoma (MEC) are reported with the most common sites being the soft tissue of skin, lung, liver, and bone. We report here a very rare case of MEC with multiple metastases to the kidney, adrenal gland, skull and gluteus maximus muscle. CASE REPORT: A 63-year-old male patient presented with left-sided headache. Radiologic evaluations including CT and MRI showed ill-defined soft tissue lesion involving the left infratemporal fossa and left sphenoid sinus, and multiple enlarged lymph nodes in neck and mediastinum. PET-CT demonstrated multiple hypermetabolic lesions in and around the left kidney, left adrenal gland, right ischium, right gluteus maximus and skull base. These lesions were confirmed as MEC with multiple metastases through biopsy. DISCUSSION: Only one case of metastasis to the skull has been previously reported, and moreover, there has not been a case of metastatic MEC to the kidney, adrenal gland and gluteus maximus muscle so far in the medical literature. It is important to acknowledge the possibility of every unusual MEC metastases, since the presence of metastasis has statistically significant influence on the survival of MEC.

RESUMO

Fatigue fracture of the pelvis is the form of fracture due to repetitive micro-stress accumulation, can be affected by a number of factors such as patient's nutritional status, biomechanics, social status and so on. Still there is no study about precise standard degree of external force that lead to stress fracture, but it may caused by compression force, traction force or complex force and others. Avulsion stress to ischial tuberosity or anterior superior iliac spine by attached muscle is known as the main factor for the avulsion fracture. This report will deal with 19 years old conscripted policeman who occurred ischial tuberosity avulsion fracture after training of 6-hour running for 5 days accompanying hip hyper-flexion motion. This reports aims to provide case study of stress fracture occurred after 5 days of exercise which is relatively short period who had no specific trauma history or pain.

RESUMO

PURPOSE: Perforator flap-using ischial sore reconstruction is performed in a prone position. But after the surgery, recurrence frequently occurs in a sitting position. In this sense, we introduce modified flap insetting method which closely resembles patient's sitting position to lessen the flap tension surgically. MATERIALS AND METHODS: Authors tried to check a skin tension difference between prone position and sitting position in normal people group and to find out the importance of performing flap insetting in hip flexion position. Healthy volunteers were collected (n=20) and designed the same length of 4 divided sections around the ischium. Lengths of each section were measured when hip joint was flexed to 90 degree and when both hip and knee joints were flexed to 90 degree and the statistical evaluation was performed. Twenty cases with ischial sore underwent reconstructive surgery using perforator flap under hip flexion position and followed-up for any recurrences. RESULTS: There was a meaningful difference between the joint flexed skin length and that of the neutral position. Flap showed sufficient thickness over 12 months. CONCLUSION: It seems that recurrence could be reduced when the reconstructed flap could sufficiently cover in a sitting position regarding its significant length difference in normal people group.

RESUMO

PURPOSE: It is generally accepted that bony reconstruction after type III (pubic) internal pelvectomy is not necessary. However, technical problems in type III resection, functional outcome according to the extent of resection, and the usefulness of synthetic material to decrease the risk of hernia has not been well addressed. MATERIALS AND METHODS: Fifteen patients who underwent type III internal pelvectomy were extracted and the pathologic diagnosis, Enneking's stage, location of tumor and size, operation time, amount of transfusion, surgical margin, local recurrence, distant metastasis, and functional outcomes were analyzed according to the extent of resection. RESULTS: Pathologic diagnosis was chondrosarcoma in 9, Ewing's sarcoma in 3, metastatic carcinoma in 2, and osteosarcoma in 1 patient. There were 4 patients with local recurrence and one with concomitant lung metastasis. Average Musculoskeletal Tumor Society functional score was 26.7. According to the extent of resection, functional score of 7 cases with unilateral both rami (6) or ischium (1) resection was 26, 4 cases with unilateral both rami and partial contralateral pubic ramus resection was 25, and 4 cases with unilateral both rami including ischium was 24. Two patients had tumor related complication. One patient with a huge intrapelvic tumor aroused at the symphysis pubis showed urethral invasion at presentation, therefore, urethral resection and permanent suprapubic cystostomy was inevitable. The other patient with bilateral pubic ramus involvement by tumor showed caudal displacement of the uterus after pregnancy (4 years after primary resection). She underwent Caesearian section for delivery. CONCLUSION: Regardless of the extent of pubic bone resection, functional outcome was similar. The risk of abdominal or pelvic organ hernia was minimal even without the use of artificial material for soft tissue reconstruction; however, when the extent of resection crosses the symphysis pubis, selective application of an additional procedure to reinforce the pelvic floor may be considered.

RESUMO

Brown tumors result from excess osteoclast activity and consist of collections of osteoclasts intermixed with fibrous tissue and poorly mineralized woven bone. They are secondary to hyperparathyroidism (HPT). Their incidence is higher in primary than in secondary hyperparathyroidism. We report a 69 years-old male, admitted in a state of confusion, lethargy and bedridden, with a pathological fracture of the femur caused by a brown tumor. The laboratory examination revealed a hypercalcemia (8.85 mEq/L), with high levels of ionized Ca (5.48mEq/L), serum alkaline phosphatases (416 U/L) and serum parathormone (120 pg/mL). Ultrasound examination of the neck showed a large parathyroid tumor, probably corresponding to a carcinoma. A primary HPT was diagnosed. The patient was hydrated and high doses of diuretics and bisphosphonates were administered. After correction of serum calcium and neurologic symptoms, the patient was operated, performing an extensive resection of the tumor. The pathology report confirmed the diagnosis of parathyroid carcinoma.


Los tumores pardos son una consecuencia de una actividad osteoclástica excesiva y consisten en osteoclastos mezclados con tejido fibroso y tejido óseo mal mineralizado. Son secundarios a hiperparatiroidismo y más comunes en hiperparatiroidismo primario. Informamos de un hombre de 69 años que ingresa confuso y letárgico con una fractura patológica del fémur causada por un tumor pardo. El laboratorio mostró hipercalcemia de 8,85 mEq/L, fosfatasas alcalinas de 416 U/L y parathormona de 120 pg/mL. La ecografía del cuello mostró un tumor paratiroideo sospechoso de carcinoma. Se diagnosticó un hiperparatiroidismo primario. El paciente se hidrató y estabilizó con diuréticos y bifosfonatos. Una vez estabilizado, se operó efectuando una extensa resección del tumor. El estudio anatomopatológico confirmó el diagnóstico de cáncer de paratiroides.

RESUMO

BACKGROUND: Reconstruction of ischial pressure sore defects is challenging due to extensive bursas and high recurrence rates. In this study, we simultaneously applied a muscle flap that covered the exposed ischium and large bursa with sufficient muscular volume and a profunda femoris artery perforator fasciocutaneous flap for the management of ischial pressure sores. METHODS: We retrospectively analyzed data from 14 patients (16 ischial sores) whose ischial defects had been reconstructed using both a profunda femoris artery perforator flap and a muscle flap between January 2006 and February 2014. We compared patient characteristics, operative procedure, and clinical course. RESULTS: All flaps survived the entire follow-up period. Seven patients (50%) had a history of surgery at the site of the ischial pressure sore. The mean age of the patients included was 52.8 years (range, 18-85 years). The mean follow-up period was 27.9 months (range, 3-57 months). In two patients, a biceps femoris muscle flap was used, while a gracilis muscle flap was used in the remaining patients. In four cases (25%), wound dehiscence occurred, but healed without further complication after resuturing. Additionally, congestion occurred in one case (6%), but resolved with conservative treatment. Among 16 cases, there was only one (6%) recurrence at 34 months. CONCLUSIONS: The combination of a profunda femoris artery perforator fasciocutaneous flap and muscle flap for the treatment of ischial pressure sores provided pliability, adequate bulkiness and few long-term complications. Therefore, this may be used as an alternative treatment method for ischial pressure sores.
