Anatomic and clinical application of lateral-perineal approach for inferior ramus of pubis-ischium ramus / 中华骨科杂志

Objective:To explore the anatomical and clinical effects of lateral-perineal approach in treating the fracture of inferior ramus of pubis-ischium ramus.Methods:The lateral approach of the perineum was simulated on 10 side of 5 intact wet adult cadavers to determine the surface symbols of incision design and to expose the operative field of the approach and to observe the anatomical characteristics of the perineal branch of the posterior femoral cutaneous nerve and the incision of the surgical approach. Five points were selected at the incision of the approach. The distance (L 1-L 5) between each point and the body surface projection of the perineal branch of the posterior femoral cutaneous nerve was measured. A total of 11 patients, including 5 males and 6 females with an average age of 41.55±14.32 years, ranging from 18 to 62 years, were treated by this approach in clinical practice. All patients had a reduction and fixation to the fracture of inferior ramus of pubis-ischium ramus. The operation duration, incision length, intraoperative blood loss and surgical complications were recorded. The quality of fracture reduction was evaluated according to Matta radiographic criteria. The strength of the adductor was measured. The pelvic function was evaluated according to Majeed Pelvic Score at the last follow-up. Results:Anatomical studies shown that the line between the two points. One point was 4 cm lateral to the level of the apex of the pubic arch. Another point was 4 cm from the ischial tubercle on the line from the ischial tuberosity to the point that 4 cm lateral to the level of the apex of the pubic arch was the axis of the approach lateral of the perineum. Anatomical studies showed that the lateral-perineal approach could expose the range from pubic symphysis to sciatic tuberculum. The distance between the points selected at the incision of the approach and the body surface projection of the perineal branch of the posterior femoral cutaneous nerve: L 1 was 19.40±1.17 mm, ranging from 18 to 21 mm; L 2 was 16.60±2.76 mm, ranging from 10 to 20 mm; L 3 was 18.30±1.89 mm, ranging from 16 to 21 mm; L 4 was 19.20±1.93 mm, ranging from 16 to 22 mm; L 5 was 14.70±1.83 mm, ranging from 13 to 18 mm. All patients were followed up for 17.91±4.09 months, ranging from 13 to 26 months. The incision length was 8.18±0.98 cm, ranging from 7 to 10 cm. The operation duration was 59.64±12.17 min, ranging from 43 to 85 min. The intraoperative blood loss was 100 ml, ranging from 50 to 130 ml. All incisions were healed in all patients. The fractures were healed in 13.36±2.06 weeks, ranging from 10 to 16 weeks. According to Matta radiographic criteria, the quality of fracture reduction was excellent in 6 cases, good in 4 cases and fair in 1 case. At the last follow-up, the adductor muscle strength reached grade 4 in 4 patients and grade 5 in 7 patients. Furthermore, according to the Majeed Pelvic Score, the score of every patient was 86.55±9.59, ranging from 66 to 100, and 8 cases were excellent, 3 cases were good at the last follow-up. The heterotopic ossification occurred in 2 patients, the pain during intercourse occurred in 2 patients. No patient had sensory disturbance or pain in the perineal area. Conclusion:A certain safe distance is between the lateral to the perineum and the perineal branch of the posterior femoral cutaneous nerve with limited risk of injuring posterior femoral cutaneous nerve via the lateral approach of the perineum. The advantages in treating the fracture of inferior ramus of pubis-ischium ramus by this approach have concealed incision, short operation duration and less bleeding with satisfied short-term clinical effects.

Abstract Objective: To determine the size of the ischiofemoral space (IFS) and quadratus femoris space (QFS) in patients with and without ischiofemoral impingement (IFI). Materials and Methods: Case-control study including consecutive patients submitted to magnetic resonance imaging (MRI) of the hip joint during a three-month period. Patients with deep gluteal pain who tested positive for IFI on at least one clinical test and showed signal changes in the quadratus femoris muscle on MRI were categorized as having a confirmed diagnosis of IFI. Results: Final sample comprised 50 patients submitted to unilateral MRI of the hip joint. The mean age was 47.3 ± 14.0 years (range, 22-76 years), and 33 (66%) of the patients were women. A diagnosis of IFI was made in 6 patients (12%), all of whom were female. On average, IFS and QFS were significantly smaller in IFI group than in control group (11.1 ± 2.7 mm versus 27.5 ± 6.5 mm and 5.3 ± 1.8 mm versus 18.8 ± 4.8 mm, respectively; p < 0.001 for both). Conclusion: Results of specific clinical tests and MRI findings indicate that the IFS and QFS are significantly reduced in patients with IFI.

Clinical strategy on repair of pressure injury on ischial tuberosity based on the histopathological type / 中华烧伤杂志

Objective@#To investigate effects of clinical strategy on repair of pressure injury on ischial tuberosity based on the histopathological type.@*Methods@#From January 2014 to January 2018, 33 patients with 33 pressure injuries on ischial tuberosity were admitted to our department. There were 25 males and 8 females aged 35 to 87 years. Pressure injuries on ischial tuberosity were repaired with different methods according to pathological types of denatured tissue on basal parts of wounds and tissue defect volumes. Areas of wounds after thorough debridement ranged from 2.0 cm×1.0 cm to 14.0 cm×12.0 cm. Pressure injuries of necrosis type with tissue defect volumes of 6.5-9.5 cm3 were sutured directly after debridement at the first stage. Tissue defect volumes of 3 patients with pressure injuries of granulation type ranged from 56.0 to 102.5 cm3. According to situation around wounds, the above mentioned 3 patients were respectively repaired with posterior femoral Z-shaped reconstruction, posterior femoral advanced V-Y flap, and posterior femoral propeller flap. Tissue defect volumes of 5 patients with pressure injuries of infection type ranged from 67.5 to 111.0 cm3. Among the patients, 2 patients were repaired with posterior femoral propeller flaps, 2 patients were repaired with posterior femoral advanced V-Y flaps, and 1 patient was repaired with posterior femoral Z-shaped reconstruction. Among patients with pressure injuries of synovium type, wounds of 14 patients with tissue defect volumes 6.4-9.5 cm3 were sutured directly after debridement, and tissue defect volumes of another 8 patients were 97.0-862.5 cm3. Among the 8 patients, 7 patients were repaired with gluteus maximus myocutaneous flaps and continued vacuum sealing drainage was performed for 7 to 14 days according to volume of drainage, and 1 patient was repaired with posterior femoral propeller flap. Areas of flaps or myocutaneous flaps ranged from 3.5 cm× 2.5 cm to 14.0 cm×12.0 cm. The donor sites of flaps were sutured directly. Operative areas after operation and healing of wounds during follow-up were observed.@*Results@#The sutured sites of 33 patients connected tightly, with normal skin temperature, color, and reflux. During follow-up of 12 months, wounds of 25 patients healed well with no local ulceration, and 8 patients were admitted to our department again due to recurrence of pressure injuries on or near the primary sites. Pathological types of pressure injuries of the 8 patients were synovium types. After complete debridement, the tissue defect volumes were 336.8-969.5 cm3, wounds with areas ranged from 8.0 cm×7.0 cm to 14.0 cm×12.0 cm were repaired with gluteus maximus myocutaneous flaps or posterior femoral propeller flaps which ranged from 8.0 cm×7.0 cm to 14.0 cm×12.0 cm. Eight patients were discharged after wound healing completely. During follow-up of 12 months, operative sites of the patients healed well, with no recurrence.@*Conclusions@#Appropriate and targeted methods should be chosen to repair pressure injuries on ischial tuberosity based on the pathological types. Direct suture after debridement is the first choice to repair pressure injury of necrosis type. Pressure injuries of granulation type and infection type can be repaired with posterior femoral propeller flap, Z-shaped reconstruction, or advanced V-Y flap according to situation around wounds. Gluteus maximus myocutaneous flap is the first choice to repair pressure injury of synovium type. In addition, recurrence-prone characteristics of pressure injury of synovium type should be taken into consideration, plan should be made previously, and resources should be reserved.

A dual padding method for ischial pressure sore reconstruction with an inferior gluteal artery perforator fasciocutaneous flap and a split inferior gluteus maximus muscle flap

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.

Magnetic Resonance Imaging for Ischiofemoral Impingement Syndrome / 中国医学影像学杂志

Purpose To explore the diagnostic value of quantitative measurements of magnetic resonance images (MRI) in transverse and coronary sections in patients with ischiofemoral impingement (IFI) syndrome.Materials and Methods The data of 70 patients (127 hips) in the Affiliated Hospital of Chengde Medical College from 2013 June to 2016 April who were performed hip MRI examination was analyzed retrospectively.39 patients (67 hips) with clinical diagnosis of IFI syndrome were selected as case group,while the other 31 patients (58 hips) with clinical exclusion of IFI syndrome were selected as control group.Ischiofemoral space (IFS),quadratusfemoris space (QFS),ischial angle,femoral neck angle (FNA) and lesser trochanter angle (LTA) were measured on axial MR image with PDWI FS sequence.The cervicodiaphyseal angle (CCD) was measured on coronary section MR image with T2WI TIRM sequence.The above measurements of two groups were analyzed.Results IFS,QFS and LTA in patients of case group were 12.2 (10.2-13.9) mm,8.5 (6.9-10.4) mm and (13.8±0.7) °,while these measurements were 26.3 (22.9-30.4) mm,21.6 (19.5-25.4) mm and (19.9± 1.0) ° in patients of control group.Compared with control group,these measurements were significantly lower in case group (P＜0.01).Ischial angel,FNA were significantly higher in case group compared with control group [(131.2±0.4) ° vs.(127.1±0.6) °,29.2 (22.8-34.1) ° vs.22.7 (19-28.3) °,P＜0.01].CCD showed no significant difference between the two groups (P＞0.05).QFS,LTA have positive correlation with IFS in case group (r=0.870 and 0.653,P＜0.05),while FNA,ischial angel have significant negative correlation with IFS in case group (r=-0.623 and-0.655,P＜0.05).The cut-offvalues ofQFS,FNA,ischial angel and LTA were ≤ 12.7 mm,≥ 21.75 °,≥ 131.65 °,≤ 9.3°,respectively.Conclusion The reduction ofIFS and QFS is the main imaging signs of IFI syndrome.

Apophyseal Avulsion Fracture of Ischial Tuberosity during Soccer: A Case Report and Literature Review / 대한스포츠의학회지

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.

Objective To discuss effectiveness of gracilis muscle flap for treatment of degree 3 and 4 pressure ulcers on ischial tuberosities for elderly patients.Methods From January 2010 to June 2015,19 elderly patients with pressure ulcers on the ischial tuberosities were enrolled,including 11 males and 8 females with an average age of 71.3 years ranging 62 to 86 years.The average course of disease was 9.6 months ranging 2 to 23 months,including 7 cases of degree 3 and 12 cases of degree 4 according to the National Pressure Ulcer Advisory Panel (NPUAP).All cases were treated by gracilis musle flap after debridement.Results All muscle flaps survived without necrosis,2 cases had wound dehiscence after operation and were healed after symptomatic treatment,and the 17 wounds were healed for first intention.All patients were followed up for 6 months to 5 years.Pressure ulcer on the ischial tuberosities recurred in 1 case after operation and was healed by debridement and suture.Pressure ulcers did not recur in the rest cases.Conclusions Gracilis muscle flap in the treatment of degree 3 and 4 pressure ulcers on the ischial tuberosities has remarkable curative effect and high cure rate in elderly patients,it is worthy of clinical application.

Hip Flexion during Intraoperative Insetting of a Perforator Flap for Reconstruction of an Ischial Sore

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.

Ischial Tuberosity Avulsion Stress Fracture after Short Period of Repetitive Training / 대한고관절학회지

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.

Ischio-Pubic-Patella Syndrome.

Abstracts: It has been stated that regulation of the development of the iliac bone is different from that of the ischium and pubis. There are well-known clinical syndromes concerned with hypoplasia of ischiopubic bone, such as small patella syndrome, nail-patella syndrome, ischiopubic-patellar hypoplasia, and ischiopubic hypoplasia. A 3 year male child presented with right knee pain since 2 weeks. She sought advice from an orthopedic surgeon and was advised for x-ray right knee. On reviewing the X-ray patella were absent and then further X-rays of left knee , pelvis , spine, elbow and foot were taken on suspicion of ischio pubic patellar dysplasia (IPD) or small patella syndrome. Patient had absent patella on left side and bilateral defective ischio pubic ossification with no spinal, elbow or foot abnormalities.Bilateral inferior ischiopubic hypoplasia along with bilateral patellar aplasia with no spinal, elbow or foot abnormalities probably constitutes a new syndrome. To the best of the author's knowledge, this finding has not been described previously.

Role of Ischio-Pubic Index in Sex Identification from Innominate Bones in North Indian Population.

Background: The use of coxal elements for age & sex identification is primary and most widespread way of bringing us closer to the identity of dead individuals in archaeological & certain forensic scenarios. It is well known that there is metric & morphologic variation in expression of sexual dimorphism between racial phenotypes and populations. Therefore, the purpose of present research is to assess metric differences in the pubo-ischial region of hip bones amongst North Indian Population. Material & Methods: Material for the current investigation comprised of 100 hip bones [(M: F=80:20) & (R: L=50:50)] obtained from Department of Anatomy, Government Medical College, Amritsar, Punjab, India. Pubic Length & ischial length were measured and Pubo-ischial index was calculated. All the data thus obtained was compiled, tabulated and statistically analyzed. Results: All the three parameters showed statistically significant sex differences. Ischium was longer in males, pubis in females & pubo-ischial index was also more in females. Conclusion: These variables can be used to determine sex from human hip bone or its fragments.

Platelet-rich plasma for treatment of ischiogluteal bursitis / 中国组织工程研究

BACKGROUND:Ischiogluteal bursitis has been recognized for a long time, but its treatment stil limits to local blocking injection and surgery methods that were developed 40 years ago. OBJECTIVE:To observe the efficacy of platelet-rich plasma on ischiogluteal bursitis. METHODS:Data of 15 patients with ischiogluteal bursitis were colected. Al the patients with ischiogluteal bursitis were treated with bilateral platelet-rich plasma (n=10) or local blocking injection (n=5). Patients’ outcomes were assessed by visual analogue scale, the Treatment Satisfaction Questionnaire for Medication (TSQM) Version II and recurrence rate. The folow-up time was from 6 to 14 months. RESULTS AND CONCLUSION: There was no statistical difference in visual analogue scale score between the platelet-rich plasma group and local blocking group (F=0.219,P=0.643), but the score of visual analogue scale in the platelet-rich plasma group was higher during short-term folow-up (within 1 week after treatment), but lower in the long-term folow-up. In the aspects of overal satisfaction score, clinical effectiveness and side effects, the platelet-rich plasma group was inferior to the local blocking group at short-term folow-up, especialy at 1 week after treatment; however, these scores became better in the platelet-rich plasma group than the local blocking group during the long-term folow-up period. In addition, no statistical difference in the convenience score was found between the two groups. At the last folow-up, the recurrence rate in the platelet-rich plasma group was lower than that in the local blocking group. Both the platelet-rich plasma and local blocking injection can significantly reduce the pain of patients with ischiogluteal bursitis. Local blocking injection has better short-term effectiveness. Platelet-rich plasma injection works moderately, but its effectiveness can last for longer time, and the recurrence rate is lower.

Treatment of Ischial Pressure Sores with Both Profunda Femoris Artery Perforator Flaps and Muscle Flaps

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.

Impacto isquiofemoral: uma etiologia de quadril doloroso: relato de caso / Ischiofemoral impingement: an etiology of hip pain: case report

A associação entre dor no quadril, anormalidade do músculo quadrado femoral na ressonância magnética (RM) e estreitamento do espaço isquiofemoral tem sido relatada na literatura atual, levantando a possibilidade de que essa lesão muscular seja causada pelo impacto isquiofemoral. Tal diagnóstico foi observado em algumas mulheres de meia-idade com ou sem história de trauma ou cirurgia. Os autores relatam aqui uma mulher de 31 anos de idade, que apresentava dor no quadril sem história de trauma, com evidência de estreitamento do espaço isquiofemoral e edema no músculo quadrado femoral. Foi realizado tratamento não cirúrgico com alívio dos sintomas. O diagnóstico de impacto isquiofemoral deve ser considerado em pacientes do sexo feminino com queixa de dor no quadril sem outra causa evidente.

An association between hip pain and quadratus femoris muscle abnormality on magnetic resonance imaging (MRI) with concurrent narrowing of the ischiofemoral space has been reported in the recent literature. This raises the possibility that the muscle damage observed is due to ischiofemoral impingement. This diagnosis has been noted in middle-aged females either with or without a history of trauma or surgery, is a rarely described feature. We report here on a 31-year-old woman who presented with non-traumatic hip pain and evidence of narrowing of the ischiofemoral space and edema in the quadratus femoris. Nonsurgical treatment was administered, which relieved her hip pain. The diagnosis of ischiofemoral impingement should be considered in female patients complaining of hip pain without any other evident cause.

Ischial Pressure Sore Reconstruction Using Inferior Gluteal Artery Perforator Flap

PURPOSE: The ischial area is by far the most common site of pressure sores found in wheel chair bound paraplegic patients, because greatest pressure is exerted from the body on this area in a sitting position. Even after a series of successful pressure sore treatments, the site is very prone to relapse by the simplest ordinary tasks of everyday life. Therefore, it is crucial to preserve the main pedicle during primary surgery. Various surgical procedures employed to treat pressure sores such as myocutaneous flap and perforator flap have been introduced. After introduction of ischial sore treatment using the inferior gluteal artery perforator (IGAP) has been made, the authors experienced favorable clinical results of patients who have undergone IGAP flap procedure in a three year time period. METHODS: A total of 17 patients received IGAP flap surgery in our hospital from January 2003 to May 2006, among which 14 of them being males and 3 females. Surgery was performed on the same site again in 6(35%) patients who had originally relapsed after receiving the conventional method of pressure sore surgery. Patients' average age was 49.4(27-71) years old. Most of the patients were paraplegic(11 cases, 65%) and others were either quadriplegic(4 cases, 23%) or ambulatory(2 cases, 12%). Based on hospital records and clinical photographs, we have attempted to assess the feasibility and practicability of the IGAP flap procedure through comparative analysis of several parameters: size of defective area, treatment modalities, occurrence of relapses, complications, and postoperative treatments. RESULTS: The average follow-up duration of 17 subjects was 25.4 months(5-42 months). All flaps survived without any necrosis. Six cases were relapsed cases from conventional surgical procedures. All of them healed well during our follow-up study. Postoperative complications such as wound dehiscence and fistula developed in some subjects, but all were well healed through secondary treatment. A total of 2 cases relapsed after surgery. CONCLUSION: The inferior gluteal artery perforator flap is an effective method that can be primarily applied in replacement to the conventional ischial pressure sore reconstructive surgery owing to its many advantages: ability to preserve peripheral muscle tissue, numerous possible flap designs, relatively good durability, and the low donor site morbidity rate.

Reconstruction of Ischial Pressure Sore by Using Posterior Thigh Transposition Flap

The area overlying the ischium is a frequent site for the development and recurrence of pressure sores because they directly overlie the points of maximum pressure on the sitting surface. Furthermore, they are frequently complicated by abnormal lesional bursae, or by extension, fistula toward the perineum or peritoneal cavity. In all cases of the ischial pressure sores, total en bloc excision of the ulceration, underlying bony prominence with immediate closure, and healthy, well-vascularized soft tissue is required to obtain the satisfactory result. It is well known that the choice of the treatment of the ischial pressure sore is the gluteal or posterior thigh flap. There have been many reports on the reconstruction of the ischial pressure sores such as cases involving the fasciocutaneous flap, muscle and musculocutaneous flaps, V-Y advancement flaps, rotation flaps, and long random flaps. In spite of these varieties, the recurrence of the ischial pressure sore after treatment still remains about seventy-five percent according to Conway and Griffith.9 Consequently, any surgical plane for ischial pressure sores must provide a stable, durable soft tissue cover that can be reused in the event of recurrence. From February to December 2002, we have performed the reconstruction of the ischial pressure sores on the posterior thigh's transposition flap in order to get following advantages: simplicity of the operation, sufficiency of padding with skin flap, preservation of the adjacent normal tissues and the capability of recycling this same flap in case of recurrences. Its design is somewhat different from and more extended widely than that of the gluteal or posterior thigh flap. This flap was elevated above the deep fascia to be cutaneous with appropriate backcut incision; some perforators from the inferior gluteal artery were also preserved. We present some cases of ischial pressure sores treated with a laterally based posterior thigh transposition flap herein. Therefore, the need to perform repetitive surgery in the future must be considered so that the maximum number of reconstructive options can be preserved. Although the follow-up period has not always been satisfactory, we have not had any serious complications in these patients until recently.
