Safety and efficacy of sacrospinous vault suspension.

The objective of the study was to determine the success rate and complications of sacrospinous vault suspension when performed by an experienced surgeon. Retrospective data collection was performed for 293 women who had undergone sacrospinous vault suspension at Mount Sinai Hospital, Toronto, between November 1993 and 19 December 1998. Primary outcome measures were complication rates (acute and long term) and success rate, with failure defined as any degree of vault prolapse requiring repeat operation, any degree of symptomatic isolated vault prolapse, or any vault prolapse at or beyond the introitus. Statistical analysis was performed using simple descriptive techniques. During the study period, 305 sacrospinous vault suspensions were performed; however, 12 cases were excluded because of inaccessible records. This study therefore comprised the remaining 293 cases: 129 at the time of vaginal hysterectomy, 5 with transvaginal cervical stump excision, 155 for post-hysterectomy vault prolapse, and 4 without hysterectomy. Two hundred had follow-up of 1 year or more, with maximum follow-up 5 years. Of these 200, there were 6 failures (3%). There were no acute hemorrhages and no deaths. There was a complaint of postoperative right buttock pain in 18 of the 293 procedures (6.1%), with this persisting on a chronic basis in 3 patients. Eight patients complained of new-onset postoperative dyspareunia. Nine patients had postoperative stress urinary incontinence, and 14 patients had de novo anal incontinence. Postoperatively, there were 17 patients with a cystocele and 7 with a rectocele. There were three other complications: one pelvic hematoma at the sacrospinous suspension site, one right foot drop which spontaneously resolved, and one case of pain in the right sciatic nerve distribution which spontaneously resolved. Forty-three patients complained of anal incontinence preoperatively, and 38 (88.4%) had the symptoms resolved postoperatively. It was concluded that, when performed by a surgeon experienced in the procedure, sacrospinous vault suspension is safe and effective, with a successful result at 1 year in more than 90% of cases, and rare major complications.

Imaging features of ischial bursitis with an emphasis on ultrasonography.

OBJECTIVE: The aim of this study was to evaluate the imaging features of ischial bursitis with an emphasis on ultrasonography (US). DESIGN AND PATIENTS: Our study included 31 patients with a painful mass or tenderness in their buttock who underwent US (n=27), CT (n=1), or MR imaging (n=4). A needle aspiration (n=6) or a bursal excision (n=5) was performed in those patients who had no clinical improvement in spite of the conservative treatment. Evaluation included lesion location, size, wall of the bursae, and intrinsic characteristics on US, CT and MR imaging. RESULTS: Ischial bursitis was superficial to the ischial tuberosity in all patients (n=31). The lesion ranged from 1.5 cm to 7 cm (average 3.8 cm) in diameter. The bursal wall was identifiable in 25 cases (81%). Internal septa and mural nodules were seen in 12 (39%) and 17 cases (55%), respectively. Sonography showed that fluid within the bursa was hypoechoic (59%), hyperechoic (26%), or of mixed echogenicity (15%). The bursae were compressible by the transducer. Power Doppler examination (n=7) showed hypervascularity of the bursal wall. All lesions imaged with contrast-enhanced CT and MR imaging had an enhancing thin wall and mural nodule. CONCLUSIONS: Ischial bursitis, superficial to the ischial tuberosity, can be clearly demonstrated on sonography and appears as a thin-walled cystic lesion, with or without internal septa and mural nodules.

L5 radiculopathy due to sacral stress fracture.

We report the case of a 70-year-old man who presented with a history of left buttock pain with radiation into the left leg in an L5 distribution. MRI of the lumbar spine revealed a left sacral stress fracture with periosteal reaction involving the left L5 nerve root anterior to the sacral ala. With spontaneous healing of the fracture, the patient's symptoms resolved completely.

MRI of hemangiopericytoma in the sacrum.

Osseous hemangiopericytoma is rare. We present a case of a 30-year-old woman with low-back pain with radiation to the left buttock for 1 month. Magnetic resonance imaging (MRI) showed a tumor mass with areas of serpentine signal void pattern in the sacrum suggestive of a vascular tumor. Neither calcifications nor layered blood serum were noted. Histological diagnosis was compatible with osseous hemangiopericytoma.

Radiculopathy due to microfibrillar collagen hemostat mimicking recurrence of disc herniation.

Microfibrillar collagen hemostat (Avitene) is an absorbable topical hemostatic agent prepared from purified bovine corium collagen. A 65-year-old woman presented with left buttock and lower extremity radicular pain. The patient underwent a disc excision in which Avitene was used to control venous bleeding from the epidural space. Leg pain decreased postoperatively, but she developed radicular pain when she started walking 3 days after the operation. Magnetic resonance imaging (MRI) performed post-operatively showed there was a mass lesion located between the dural sac and L5 nerve root. The lesion exhibited high signal intensity on T1-weighted images and higher signal intensity at the rim of the mass on T2-weighted images. A second operation performed 10 days later revealed that the nerve root was adherent to an extradural granulomatous mass associated with Avitene. Macroscopically, the resected mass was found to be composed mainly of microfibrillar collagen hemostat materials. Hemostat agents may produce a clinically symptomatic, radiologically apparent mass lesion. When considering a mass lesion arising after spine surgery, the differential diagnosis should include foreign body granuloma along with recurrent disc herniation and peridural scar formation.

Primary atypical sacral meningioma--not always benign.

We present a case of an atypical recurrent meningioma of the sacrum with pulmonary metastasis in a 31-year-old man. He presented with deep-seated buttock pain and urinary hesitancy for 3 months. MRI revealed a lesion occupying the central and left side of the sacral canal at the S1-S2 level. Surgical excision of the lesion via a posterior approach was undertaken, and the patient became symptom-free post-operatively. Histology confirmed atypical meningioma. Eight months later he re-presented with similar symptoms, and MRI confirmed local recurrence. The patient underwent left hemisacrectomy. Six months later he again presented with low back pain and MRI confirmed a second local recurrence. A CT scan of the chest showed multiple lung metastases. The patient died of a severe chest infection 18 months later.

Cauda equina syndrome presentation of sacral insufficiency fractures.

INTRODUCTION: Sacral insufficiency fractures are a well recognised cause for low back, buttock and groin pain in the elderly. However, over a 4 year period, four patients have presented with symptoms of cauda equina syndrome, who were found on investigation to have acute sacral insufficiency fracture without any other aetiological spinal abnormality. PATIENTS AND METHOD: Four patients who presented to the spinal surgeons of our institution with symptoms of cauda equina syndrome were referred for spinal MR. Sagittal and axial T1 and T2 weighted turbo spin echo sequences of the lower thoracic and lumbar spine were performed on all patients. Subsequent studies included MR of the sacrum supplemented where appropriate by CT and technetium MDP bone scintigraphy. RESULTS: No evidence of a compressive lesion of the lower thoracic or lumbar spine was present in any of the four patients. Dedicated MR examination of the sacrum in these patients revealed unilateral acute insufficiency fractures involving zone 1 from S1 to S3 extending from the sacro-iliac joint to the lateral margin of the sacral foramen. There was no evidence of compression of the sacral nerve roots. The possible mechanism for the symptomatic presentation is discussed. CONCLUSION: Sacral insufficiency fractures should be excluded in elderly or osteoporotic patients presenting with cauda equina syndrome who have no evidence of compression in the thoraco-lumbar MR studies.

Sacroiliac joint tuberculosis.

Infections of the sacroiliac joint are uncommon and the diagnosis is usually delayed. In a retrospective study, 17 patients who had been treated for tuberculosis sacroiliitis between 1994 and 2004 were reviewed. Two patients were excluded due to a short follow-up (less than 2 years). Low back pain and difficulty in walking were the most common presenting features. Two patients presented with a buttock abscess and spondylitis of the lumbar spine was noted in two patients. The Gaenslen's and FABER (flexion, abduction and external rotation) tests were positive in all patients. Radiological changes included loss of cortical margins with erosion of the joints. An open biopsy and curettage was performed in all patients; histology revealed chronic infection and acid-fast bacilli were isolated in nine patients. Antituberculous (TB) medication was administered for 18 months and the follow-up ranged from 3 to 10 years (mean: 5 years). The sacroiliac joint fused spontaneously within 2 years. Although all patients had mild discomfort in the lower back following treatment they had no difficulty in walking. Sacroiliac joint infection must be included in the differential diagnosis of lower back pain and meticulous history and clinical evaluation of the joint are essential.

Conservative management of local Mycobacterium chelonae infection after combined liposuction and lipofilling.

A case of Mycobacterium chelonae infection in the buttock after combined liposuction and lipoinjection is presented. The real possibility of contamination from operating room equipment was the potential etiologic factor of this infection. The clinical presentation of the disease was typical. The difficulty confirming the diagnosis was solved by specific culturing techniques. Successful treatment with limited debridement and irrigation combined with prolonged specific antibiotic therapy effected a long-term cure.

Long-term outcome of undifferentiated spondylarthropathy.

Undifferentiated spondylarthropathy is one of the common disease subsets in the group of so-called seronegative spondarthritides. It is not exactly known how often it differentiates into ankylosing spondylitis or other well-defined disease subsets over time. The present study was designed to find out the long-term outcome in this subset. Thirty-five patients diagnosed with undifferentiated spondylarthropathy between January 1987 and December 1988 were recruited. Twenty-two (63%) of them were available for detailed assessment 11 years after the original diagnosis. Their baseline characteristics did not differ from those of the original cohort of 35 patients and were as follows: male:female ratio 19:3, median age of onset 17 years (range 8-39), and median duration of disease 8 months (range 4-24). Clinical features were enthesitis (45%) and inflammatory pain in the back (100%), buttock (77%), hip (64%), shoulder (18%), knee (82%), ankle (77%), and hand and wrists (50%). There was no restriction in spinal movement. Family history was positive in two cases. Radiologically, the only finding was grade I sacroiliitis in 17 patients (77%). Human leukocyte antigen (HLA)-B27 was positive in all. Functionally, all were in class I. During follow-up, one patient developed psoriatic skin lesions after 9 years. Uveitis developed in four patients (18%). After a median follow-up of 11 years, 15 (68%) had ankylosing spondylitis, one developed psoriatic arthritis, four remained undifferentiated, and two had natural remission. Functionally, 19 patients (86%) were in class I and three (14%) were in class III. No patient had bamboo spine, but three underwent total hip replacement. Thus, a majority of patients (68%) with undifferentiated spondylarthropathy gradually developed ankylosing spondylitis of mild severity.

Fatigue stress injuries of the pelvic bones and proximal femur: evaluation with MR imaging.

The purpose of this study was to determine the prevalence and the distribution as well as male/female differences in patients with hip or pelvic pain based on MRI results. Three hundred forty consecutive conscripts (45 women, 295 men; age range 18-29 years; mean age 20.7 years) suffering from stress-related hip, buttock or groin pain took part in the study. All 340 patients underwent MR imaging. Radiographic data were available for 215 patients. Two radiologists interpreted the images by consensus. In MRI 174 stress injuries were diagnosed in 137 patients (32 women, 105 men). The incidence of bone stress injuries in women was significantly higher than that in men ( p<0.0001). One hundred five of the injuries (60%) were related to the proximal femur, 70 (67%) to the neck, 34 (32%) to the proximal shaft, and one (1%) to the head. Sixty-nine of the 174 stress injuries (40%) concerned the pelvic bones: sacrum 28 (41%); inferior pubic ramus 34 (49%); superior pubic ramus 3 (4%); iliac bone 3 (4%); and acetabulum 1 (1%). In 31 of the 174 cases (18%) symptoms were contralateral to MR findings. Thirty-three of the 137 patients (24%) had multiple bone stress injuries, 29 had two bone stress injuries and 4 patients had three. The sensitivity of radiography was 37%, specificity 79%, accuracy 60%, positive predictive value 59% and negative predictive value 61%. The kappa value for agreement between radiography and MRI was poor (0.17, p=0.0008). Patients suffering from stress-related hip pain MRI revealed bone stress injuries in 40%; of these, 60% were located in the proximal femur and 40% in the pelvic bones. For accurate diagnosis of bone stress injuries, and to ensure appropriate treatment, the entire pelvis and both proximal femurs should be studied simultaneously by means of MRI.

Malignant triton tumor in the thoracic spine.

We present a 15-year-old patient diagnosed with peripheral neurofibromatosis (NF-1), who was admitted with paraparesis caused by a large intrathoracic tumor with an intracanalicular component that affected the spinal cord. After surgery his condition improved, but a year later he suffered a relapse and died. Histologically the tumor was diagnosed as malignant with neurogenic and myogenic differentiation ("malignant triton tumor"). Malignant triton tumors (MTT) are infrequent; those found in the head and neck and the upper or lower extremities have a better prognosis than those in the retroperitoneum, buttock, or trunk. It is not clear whether this variation is due to a difference in tumor grade, stage, or resectability, or whether it is a consequence of therapy.

Lipoblastoma/lipoblastomatosis: a clinicopathologic study of 16 cases in Taiwan.

Lipoblastoma/lipoblastomatosis is an uncommon benign lipomatous tumor affecting mainly infants and children. It presents as a painless mass located frequently in upper and lower extremities. The present study was conducted to characterize the clinicopathologic features of lipoblastoma/lipoblastomatosis in a Chinese population. A retrospective survey of 16 cases of pathologically confirmed lipoblastoma/lipoblastomatosis from 1988 to 2002 was performed. The available clinical information and histological sections were reviewed. The study involved 10 males and 6 females ranging in age from 5 to 49 months (median, 11.5 months). The patients presented with mass involving neck (n = 5), inguina (n = 3), feet (n = 2), arm (n = 1), leg (n = 1), thorax (n = 1), mesentery (n = 1), buttock (n = 1), and presacral region (n = 1). The lesions were removed surgically. Histologically, the majority (11/16) of primary tumors were of diffuse type. Follow-up ranging from 5 to 125 months was available in 13 patients. Four patients experienced a recurrence of tumors in the neck (n = 2) and lower extremities (n = 2) 11-84 months after operation. The most common site of involvement of lipoblastoma/lipoblastomatosis in our series was the neck. A follow-up period of more than 3 years is recommended for patients with this condition.

Rapid rehabilitation programme following sacral stress fracture in a long-distance running female athlete.

Stress fractures occur in normal bone due to mechanical overload by cyclic stress increasing the osteoclastic activity, thus facilitating weakening leading to fracture of bones. Long-distance running may lead to stress fractures of the mid- and distal tibia and of the metatarsal bones. Stress fractures to the sacrum are rare. Certain factors for stress fractures in runners have been identified, such as leg-length inequality, a high longitudinal arch of the foot, forefoot varus, and menstrual irregularities in case of female athlete triad. We report on a 22-year-old female runner (usually training 140 km/week) suffering a sacral fatigue-type fracture. The female athlete triad with eating disorders, dysmenorrhea, and osteopenia was ruled out. Sexual hormone blood samples proofed normal values. The diagnosis was performed using magnetic resonance imaging 2 weeks after the onset of buttock pain. A conservative treatment regimen was initiated with strict physical rest for the first 2 weeks, and then gradual increase of physical activity with 60-90 min of daily cycling and moderate 2 x 60 min cross-training. After another 2 weeks time, daily 60-90 min of walking, Nordic pole walking, and moderate strength training two times a week was performed. At 7 weeks running was started, gradually increased to 90 km/week without any pain. A rapid rehabilitation programme after sacral stress fractures involving low impact physical activity, such as Walking and Nordic pole walking, is applicable to female athletes after ruling out the female athlete triad.

Aneurysm of a persistent sciatic artery.

We report a case of an aneurysm of a persistent sciatic artery which caused buttock pain. Preoperative diagnosis is very difficult. However, awareness of the presence of this rare embryonic abnormality is important, especially in elderly persons with atherosclerotic changes. Sagittal magnetic resonance imaging (MRI) was very useful in reaching this diagnosis.

Labor analgesia for the parturient with lumbar tattoos: what does an obstetrician need to know?

Tattoos-ancient forms of permanent body ornamentation (body art) have today become popular fashion accessories worldwide. More than 50% of all tattoos are being done on women. In the recent years body tattooing in unconventional sites (e.g. lumbar and/or sacral area, lower abdomen, breast, and buttocks) has gained increasing popularity among young women (including in pregnancy). Although, the potential hazards of regional anesthesia in patients with lumbar tattoos remain controversial it may seem prudent to avoid a hollow needle insertion (possible tissue entrapment in its bore as the needle passes to the deeper structures) through a tattoo for neuraxial blocks. This author is not aware of any other review articles in English literature discussing implications, and complications of labor analgesia in parturients presenting with lumbar tattoos.
