Giant-cell tumor is considered one of the benign tumors which is predilected at an ends of a long bone. Although many reports of giant-cell tumor affecting the sacrum have been recentIy presented, the report of the tumor involving coccyx is not comparatively frequent. A case of relatively uncommon giant-cell tumor involving the coccyx is presented with the review of the relevant literature.

Lumbosacral fixation or spinopelvic fixation is frequently required for the surgical treatment of neuromuscular scoliosis and degenerative lesions, trauma and tumor in the lumbosacral vertebrae. However, the establishment of stable fixation with these procedures is difficult due to the anatomic characteristics of the sacrum and this is even more problematic for the cases with long segmental fixation, severe instability and bone defects. Although the emergence of pedicle screws makes spinal fixation easier and more rigid, S1 pedicle screws alone do not provide enough stability for lumbosacral fixation. For the purposes of reinforcing lumbosacral fixation, procedures using rods or screws can be used: the procedures using rods include the Galveston method, the McCarthy S-rod and the Jackson intrasacral rod, and the procedures using screws include sacral alar screws, transdiscal screws and iliac screws. The purpose of this study was to ascertain the proper fixation methods, according to each indication, for spinopelvic fixation and we analyzed the advantages and drawbacks of each fixation method. In addition, the fixation method of iliac screws, which has recently become more popular, is presented in detail to enhance the availability and reduce the complication of this technique.

Displaced fractures of the upper sacrum are a rare type of high energy injury, such as a fall, with similar neurological symptoms and fracture patterns. The authors treated 4 patients with these fracture patterns surgically or conservatively and followed them up for at least 1 year. We report these 4 cases with a review of the relevant literature.

Intraosseous pneumatocyst is a benign, gas-filled, cystic lesion, and is commonly encountered in iliac bone or sacrum. Other locations of this lesion following trauma are rare, and only a handful of isolated cases have been reported. The pathogenesis and etiologies of this uncommon entity are various and it can present a diagnostic challenge. Only four previous cases have described the natural course of intravertebral pneumatocysts. Here, the authors report a rare case of traumatic pneumatocyst, which resolved rapidly without further complication. Possible pathogenic mechanisms are discussed and reviews of literatures are included.

A wide transfixing suture including sacrum successfully controlled severe presacral hemorrhage during rectal resection. The basic principle of this technique lies in safe tamponade of injured fragile vessels attached to sacral periosteu. This technique can be equipped as one of the efficient armamentarium competing lethal presacral hemorrhage during pelvic surgery.

Evaluation of the sacrum in anorectal malformations (ARMs) is important because of the frequent association with ARMs and functional outcome after correction of ARMs. Sacral defects are not easily detected because of immaturity of sacrum in children and overlooking of pediatric surgeons. The authors utilized the sacral ratio in normal children and patients with ARMs. In normal children, the mean true sacral ratio and mean sacrococcygeal ratio were 0.60+/-0.08 and 0.72+/-0.13 respectively. Sacral ratio was not correlated with age and did not changed with age in same patient. However, true sacral ratio and sacrococcygeal ratio were significantly lower in patients with high type ARMs than those of normal children (p<0.001). There was no difference between patients with low type ARMs and normal children. These results suggest that abnormal sacrums are more frequently encountered in patients with high type ARMs than in normal children, and that true sacral ratio and sacrococcygeal ratio can be used in the evaluation of the abnormal sacrum.
