Insufficiency fractures of the ilium.

Insufficiency fractures often occur in the sacrum and pubic rami but have rarely been reported in the ilium, where their frequency may be underestimated. We studied a series of 14 patients with insufficiency fractures of the ilium. Six patients had an oblique fracture through the wing of the ilium (which was bilateral in one case) and nine a supraacetabular fracture, with in one case a superomedial extension into the iliac wing. The initial radiographs were normal, making the diagnosis difficult. A linear area of sclerosis along the fracture line was seen after a few weeks. The radionuclide examination provided early detection and often demonstrated multiple insufficiency fractures (mean 2.1 per patient). Computed tomography missed some of the fractures, whereas magnetic resonance imaging proved a reliable diagnostic tool, especially in patients with supraacetabular fractures, showing the fracture as a line of low signal surrounded by an area of edema whose contours were exactly the same as those of the hyperactive focus on the radionuclide scan. Osteoporosis was a causative factor in all 14 patients and vitamin D deficiency in seven. Also, three patients had a history of fluoride therapy.

[Long-term management results of Pemberton's ilium osteotomy in combination with inter-trochanter derotation-varisation osteotomy in hip dysplasia of childhood].

AIM: The aim of the present study was to obtain long-term functional and radiographic results after a pericapsular osteotomy of the ilium (Pemberton) and a simultaneously performed derotation-varisation osteotomy of the proximal femur in children with developmental dysplasia of the hip (DDH) after the end of the maturity process. METHOD: The clinical results and x-ray measurements of 79 patients with 100 operated hips were analysed. The average follow-up time after surgery was 14 years and 7 months (range: 10.4 to 19.5 years). The indication for operation was determined using the acetabular angle of more than two standard deviations. RESULTS: The clinical investigation shows that 85 % of the operated patients had no functional limitations. 14 % of the patients had minor limitations and 1 % had major limitations in their hip movement. No patient suffered constant hip pain; 62 % had no pain even after long walking; 32 % had pain after walking for more than an hour; 6 % complained of hip pain after walking for less than an hour. The radiological measurements show that 95.9 % of the patients had normal or mildly pathological ACM angle scores, and 92.8 % had normal or mildly pathological CE angle scores. CONCLUSION: Surgical treatment of residual hip dysplasia by simultaneously performed pericapsular ilium and proximal femur osteotomy is very effective. Although a radiographically almost normal acetabulum could be documented in patients after the end of the maturity process, revalgisation of the proximal femur occurred. With an appropriate acetabular correction additional osteotomy of the femur might therefore be unnecessary.

Vascular iliac crest with inner table of the ilium as an option in maxillary reconstruction.

Reconstruction of large maxillary defects has been a long-standing challenge to the reconstructive surgeon. Total maxillary reconstruction is desirable but often not possible; ideally, this would provide all the anatomical structural support, function, and esthetics missing because of the defect. A case is presented in which all the criteria for total maxillary reconstruction have been fulfilled. The patient is a 60-year-old man who had wide excision of his maxilla for ameloblastoma, followed by temporal bone flap reconstruction, which failed. He presented to our institution for further evaluation and possible treatment options; these were discussed with the patient and the multidisciplinary team that deals with congenital and acquired deformities in the head and neck area. An iliac crest free flap that included the inner table of the ilium based on the deep circumflex iliac artery was used for the reconstruction. The procedure is described, including restoration of a nasal lining. Osseointegrated implants were used for dental rehabilitation. Ameloblastoma is briefly discussed. The goals of maxillary rehabilitation and obstacles to obtaining those goals are presented. Options available for maxillary reconstruction are discussed, along with some of their advantages and disadvantages, as is the reason why the iliac crest free flap with the inner table of the ilium was chosen. An iliac crest free flap with microvascular anastomosis to facial vessels was used to reconstruct a large maxillary defect. Osseointegrated implants were used to facilitate dental rehabilitation. Our patient has excellent restoration of oronasal function with a satisfactory esthetic result.

The location of the sacroiliac joint on the outer table of the posterior ilium.

Ten cadaveric sacroiliac joints were cleaned of soft tissue and analyzed to determine the average location of the sacroiliac joint on the outer table of the posterior ilium. The superior and inferior limbs of the joint were characterized according to length and width. The longitudinal axis for each limb was determined and located on the outer table of the posterior ilium. The location of the sacroiliac joint was then characterized with respect to established anatomic landmarks. The average lengths of the superior and inferior limbs were 4.4 and 5.6 cm, respectively. The width of each limb averaged 2.0 cm. The average distance from the longitudinal axis of the superior limb to the posterior superior iliac spine was 5.5 cm. The average longitudinal axis of the inferior limb was 1.2 cm superior to the inferior margin of the posterior inferior iliac spine. The angle between the two axes averaged 93 degrees.

High-grade surface osteosarcoma of the left ilium. A case report and review of the literature.

A rare case of high-grade surface osteosarcoma of the left ilium is reported. Trephine biopsy performed on a 31-year-old woman suffering from a huge tumor of the left buttock revealed high-grade osteosarcoma, and hemipelvectomy was undertaken. The surgical specimen showed that the tumor was present on the surface of the left ilium. Ten months after the operation, the patient died of brain metastasis. From these results, we considered this case to be one of high-grade surface osteosarcoma.

Fracture of the wing of the ilium, adjacent to the sacroiliac joint, in thoroughbred racehorses.

During a two year period, sagittal fractures of the wing of the ilium were diagnosed in 10 Thoroughbred horses. All were spontaneous fractures sustained during normal exercise in training and racing, with no history of inciting trauma. When ultrasound scans of the surface of the pelvis were performed, the fracture was clearly visible as a discontinuity of the sacral wing of the ilium. In 3 horses, an irregular contour suggestive of periosteal callus was seen in the vicinity of the acute fracture. All horses examined by gamma scintigraphy had a focal increase in uptake of isotope just lateral to the tuber sacrale. Nine of the horses were treated conservatively by rest. The other horse had bilateral fractures and was subjected to euthanasia at the time of the injury. Six horses returned to full training, and 2 subsequently won, without recurrence of lameness.

Ossification of the human fetal ilium.

Ossification of the ilium is similar to that of a long bone. It possesses three cartilaginous epiphyses and one cartilaginous process. Moreover, it undergoes peculiar osteoclastic resorption, comparable with that of the cranium bones. Asymmetrical ossification of the ilium, haversian bone remodelling and apposition of chondroid tissue posterosuperiorly to the acetabulum most probably emphasize the importance of mechanical factors in the morphogenesis of the hip bone during fetal life.

[3-D finite element and clinical analyses of the reconstruction of the first to third metatarsus defect with ilium].

OBJECTIVE: To investigate the effect of first to third metatarsus defect and the effect of reconstruction with ilium on foot function. METHODS: The first to third metatarsus defect was simulated in a 3D foot model and rebuilt by ilium. The maximal displacement and stress calculated by the method of finite elements were used as the index of estimation. Five cases treated from Mar. 1996 to Jan. 2003 with metatarsus defect rebuilding by free vascular iliac bone incorporating free flap were evaluated. RESULTS: Foot function was affected largely by the defect of the first to third metatarsus. Compared with the normal foot, the maximal displacement was increased by 2.15 times and the maximal stress was increased by 2.12 times in 100%-defected foot, and in 50%-defected foot maximal displacement and stress were increased by 1.65 times and 2.05 times respectively. Follow-up had been conducted for 1 to 2 years. All bones and flaps of the 5 cases survived (2 excellent, 2 good, and 1 passable) by function evaluation. CONCLUSION: The first to third metatarsus defect should be repaired, and the method of transplanting iliac bone added by flap is effective.

[Experimental research on absorption after ilium autografting].

Even though efforts were made by closely adhering to the established rules of bone grafting, late absorption of bone grafts occurs frequently. Sometime the effect of operation is jeopardized. The cause of bone absorption is complicated, it is necessary to carry out further research. In this study 80 autogenous grafts were taken from ilium of 40 rabbits. A half of the grafts were transplanted on to cranium, the rests were implanted into subcutaneous tissue. One month later, bone grafts were absorbed 20.0% (on surface of cranium bone) and 21.0% (in subcutaneous sites). Three months after operation absorptions increased to 67.6% and 69.1% respectively. Six months later, absorption reached to 76.0% and 73.6%. There is no statistical difference between two sites where the grafts are transplanted (P greater than 0.05). Absorption of bone grafts was also found in 3 dogs. Its ilium autografts were absorbed 52.8% (over cranium) and 45.2% (in subcutaneous tissue) 3 months after operation, the former increased to 55.3% and the latter 50.1% 6 months later. Microscopic examination revealed absorption and melting of bone grafts, necrosis and cysts formation were also found in some grafts. We believe that these data may help us to recognize the absorption further after free bone autografting.

Osteolytic osteogenic sarcoma of ilium in 46-month-old boy.

A 46-month-old boy with a four-day history of pain and swelling over the right posterior ilium was thought to have acute osteomyelitis on the basis of a normal pelvic x-ray, markedly increased scintigraphic activity in the right ilium, and a mildly elevated sedimentation rate. At surgery, no signs of osteomyelitis were found, and biopsy revealed osteolytic osteogenic sarcoma. This is the youngest child with osteogenic sarcoma of the pelvic reported in the literature.

Age estimation from the auricular surface of the ilium: a revised method.

A revised method for estimating adult age at death using the auricular surface of the ilium has been developed. It is based on the existing auricular surface aging method of Lovejoy et al. ([1985] Am. J. Phys. Anthropol. 68:15-28), but the revised technique is easier to apply, and has low levels of inter- and intraobserver error. The new method records age-related stages for different features of the auricular surface, which are then combined to provide a composite score from which an estimate of age at death is obtained. Blind tests of the method were carried out on a known-age skeletal collection from Christ Church, Spitalfields, London. These tests showed that the dispersion of age at death for a given morphological stage was large, particularly after the first decade of adult life. Statistical analysis showed that the age-related changes in auricular surface are not significantly different for males and females. The scores from the revised method have a slightly higher correlation with age than do the Suchey-Brooks pubic symphysis stages. Considering the higher survival rates of the auricular surface compared with the pubic symphysis, this method promises to be useful for biological anthropology and forensic science.

Chronological metamorphosis of the auricular surface of the ilium: a new method for the determination of adult skeletal age at death.

A new method for the determination of adult skeletal age at death based upon chronological changes in the auricular surface of the ilium is presented. Formal stages have been constructed following extensive tests and refinements in observations made of such changes. Two completely "blind" tests were conducted to assess the accuracy and bias of the new method. Results show that the system is equally accurate to pubic symphyseal aging (although somewhat more difficult to apply), and also carries the advantages of a higher preservation rate for the auricular surface in archaeological populations and continued age-related change beyond the fifth decade.

New method for estimation of adult skeletal age at death from the morphology of the auricular surface of the ilium.

A new method for estimating skeletal age at death from the morphology of the auricular surface of the ilium is presented. It uses a multiple regression analysis with dummy variables, and is based on the examination of 700 modern Japanese skeletal remains with age records. The observer using this method needs only to check for the presence or absence of nine (for a male) or seven (for a female) features on the auricular surface and to select the parameter estimates of each feature, calculated by multiple regression analysis with dummy variables. The observer can obtain an estimated age from the sum of parameter estimates. It is shown that a fine granular texture of the auricular surface is typical of younger individuals, whereas a heavily porous texture is characteristic of older individuals, and that both of these features are very useful for estimating age. Our method is shown here to be more accurate than other methods, especially in the older age ranges. Since the auricular surface allows more expedient observations than other parts of the skeleton, this new method can be expected to improve the overall accuracy of estimating skeletal age at death.

Stw 441/465: a new fragmentary ilium of a small-bodied Australopithecus africanus from Sterkfontein, South Africa.

In 1986 and 1987, a hominid left ilium fragment consisting of a spina iliaca anterior superior and crista iliaca was discovered during excavations at Sterkfontein, South Africa. Although the specimen is small it gives valuable hints for muscle insertions and origins at the pelvis of Australopithecus africanus. It indicates that the anatomy of the abdominal muscles and of the mm. glutei medius et minimus of A. africanus was quite different from that of the great apes and more similar to that of modern humans. This has major implications for the interpretation of the bipedalism and locomotor efficiency of the early South African hominids.

The pericapsular osteotomy of the os ilium in the treatment of flat acetabula.

The operative correction of the pathological flat acetabulum in congenital dislocation of the hip, myelodysplasia and cerebral palsy can be performed with pelvic osteotomies and acetabuloplasties. In the light of our own experiences gained with different methods we prefer the pericapsular osteotomy of the ilium according to Pemberton since 1971. After the evaluation of the results the advantages of the method compared with other procedures are presented in the light of the improvements of correction and the rate of complication.
