摘 要:
A thorough understanding of compartmental anatomy is necessary for the radiologist participating in the care of a patient with a lower extremity musculoskeletal malignancy. Localization of tumor to compartment of origin and identification of extracompartmental spread preoperatively are needed to correctly stage a tumor and determine the appropriate surgical management. An understanding of the locations of fascial boundaries, extracompartmental tissues, and neurovascular structures of the thigh and lower leg facilitates this diagnostic process. For the radiologist planning to biopsy a suspicious musculoskeletal lesion, consultation with the referring orthopaedic surgeon is recommended in order to jointly select an appropriate percutaneous biopsy approach. Adequate preprocedural planning ensures selection of an approach which prevents iatrogenic tumor spread beyond the compartment of origin, protects neurovascular structures, and allows complete resection of the biopsy tract and scar at the time of surgical resection without jeopardizing a potential limb-sparing procedure. Cross-sectional anatomic review and case examples demonstrate the importance of a detailed understanding of compartmental anatomy when approaching the patient with a lower extremity musculoskeletal tumor.

摘 要:
OBJECTIVE: To investigate the magnetic resonance (MR) imaging appearances of chronic nonunion of the scaphoid with proximal pole avascular necrosis before and after insertion of a vascularized bone graft, using computed tomography (CT) as the imaging gold standard. DESIGN AND PATIENTS: A retrospective study was performed involving MR imaging (n=26), CT scans (n=37) and radiographs (n=52) of 13 men (mean age 29 years, age range 20-38 years) with avascular scaphoid nonunion. Avascular necrosis of the scaphoid proximal pole was confirmed intraoperatively (n=13). MR images were acquired preoperatively and following placement of a vascularized bone graft. Scaphoid MR signal characteristics were assessed for evidence of vascular bone graft incorporation and revascularization of the bone marrow of the proximal pole of the scaphoid and compared with the gold standard of CT. Surgical and clinical notes were reviewed with a minimum 3 year imaging and clinical follow-up in all patients. RESULTS: Graft incorporation with revascularization of the proximal pole of the scaphoid was documented in 9 patients (69%). Graft failure with persistent pseudoarthrosis and avascular necrosis of the scaphoid was seen in 4 patients (31%). CONCLUSIONS: MR imaging is useful to determine whether vascularized bone graft incorporation and revascularization of the proximal pole of the scaphoid has occurred in the setting of avascular scaphoid nonunion.

摘 要:
OBJECTIVE: To study the clinically diagnosed disease process but also identify additional, clinically undetected pathologies in femoral heads resected for replacement arthroplasty. DESIGN AND MATERIAL: A retrospective review was carried out of the pathological findings in 460 surgically resected femoral heads. Serial sections were submitted to low-energy fine-detail radiography, then decalcified sections stained by the WHO method were examined. The preoperative clinical and imaging diagnoses were compared with the pathological findings and special interest was placed on assessing the clinical significance of any unexpected, clinically undetected findings. RESULTS: The most common findings included the presence of bone islands (solitary osteomas) and areas of avascular necrosis in addition to the primary joint disease for which the patient underwent surgery. The preoperative symptomatology did not distinguish between the known primary disease and the additional pathological findings. CONCLUSION: Some of the clinically unidentified lesions were of a size that fell below the ability of current clinical investigations to detect. However, the finding of lesions by tissue fine-detail radiography indicates that current, more sensitive clinical imaging techniques may identify them. Careful examination of surgically resected femoral heads is important to ensure that all pathologies are identified and assessed for clinical relevance.

摘 要:
OBJECTIVE: To assess whether there are significant differences in ease of use and quality of samples among several bone biopsy needles currently available. DESIGN: Eight commonly used, commercially available bone biopsy needles of different gauges were evaluated. Each needle was used to obtain five consecutive samples from a lamb lumbar pedicle. Subjective assessment of ease of needle use, ease of sample removal from the needle and sample quality, before and after fixation, was graded on a 5-point scale. The number of attempts necessary to reach a 1 cm depth was recorded. Each biopsy specimen was measured in the gross state and after fixation. RESULTS: The RADI Bonopty 15 g and Kendall Monoject J-type 11 g needles were rated the easiest to use, while the Parallax Core-Assure 11 g and the Bard Ostycut 16 g were rated the most difficult. Parallax Core-Assure and Kendall Monoject needles had the highest quality specimen in the gross state; Cook Elson/Ackerman 14 g and Bard Ostycut 16 g needles yielded the lowest. The MD Tech without Trap-Lok 11 g needle had the highest quality core after fixation, while the Bard Ostycut 16 g had the lowest. There was a significant difference in pre-fixation sample length between needles (P<0.0001), despite acquiring all cores to a standard 1 cm depth. Core length and width decrease in size by an average of 28% and 42% after fixation. CONCLUSION: Bone biopsy needles vary significantly in performance. Detailed knowledge of the strengths and weaknesses of different needles is important to make an appropriate selection for each individual's practice.

摘 要:
OBJECTIVES: To assess the distribution of microvascular response on colour Doppler (CD) and power Doppler (PD) ultrasound (US) of the tendo Achilles (TA) in tendonopathy, and to look for any relationship between tendon morphology and symptoms. DESIGN AND PATIENTS: A retrospective, observational study was carried out on consecutive ambulant US patients with suspected tendonopathy, presenting with pain or an Achilles mass. Exclusion criteria were: use of steroids, and previous or possible rupture or surgery in either tendon or arthropathy. Using a 5-12 MHz linear array probe (ATL HDI 3000) both TAs were scanned. Tendonopathy was defined as tendon swelling and/or hypoechogenicity of the TA. The site, number and distribution of microvascularity, on CD and PD, and the anteroposterior size were recorded, with the analysis masked. RESULTS: Fifty-two patients presented with TA pain and six also with swelling. There were 34 males and 18 females, aged from 11 to 78 years (mean 45 years). Fifty-five TAs that showed tendonopathy with hypoechogenic areas were all observed to be over 5.9 mm (mean 11.1 mm, range 5.9-20 mm), of which 45 were symptomatic with abnormal PD and 24 with abnormal CD flow. It was observed that the extent and completeness of vessel branching was more extensive on PD than CD. All TAs demonstrating tendonopathy were over 5.9 mm in adults and all TAs that showed PD flow were over 6.5 mm. All microvessels originated towards the TA from the ventral surface usually into tendonopathy, and were 16-fold more frequent around the margins. There were 49 TAs with normal spectral US, and with no PD flow, with a mean size of 4.5 mm (range 3.0-7.4 mm). For the right and left TAs independently analysed and taking the 40 patients with a paired asymptomatic and symptomatic tendon: (1) There was a highly significant difference in size (P<0.00001) using the paired t-test (parametric) between the asymptomatic tendon (mean 5.2+/-1.4 mm (1 SD)), and the contralateral morphologically abnormal and symptomatic side (mean 9.7+/-1.4 mm). (2) There was no linear Pearson correlation (0.25) between TA size and duration of symptoms (P=0.11) for symptomatic tendons. (3) There was a positive Spearman correlation (0.84) between the number of vessels and TA size (P<0.00001). (4) There was a significant difference in the number of PD vessels using the non-parametric Wilcoxon signed test (P<0.00001) between the symptomatic and asymptomatic groups. CONCLUSIONS: (1) PD shows more tendon microvascularity than CD in TA tendonopathy. (2) All microvessels arise on the ventral side of the TA. (3) There is a non-linear relationship between tendonopathy, TA size and the amount of microvascularity, but not between PD and duration of symptoms. (4) Morphologically abnormal adult TAs were larger than 5.9 mm, and PD flow was only seen in TAs above 6.5 mm.

摘 要:
Lobular capillary hemangioma is a vascular neoplasm that commonly occurs as a cutaneous tumor. When it involves the skin and mucosal surfaces, ulceration and suppuration may occur, hence the classic term of pyogenic granuloma. Intravenous pyogenic granuloma is a rare solitary form of lobular capillary hemangioma that usually occurs in the veins of the neck and upper extremities. We report the ultrasonographic and magnetic resonance imaging findings of a pyogenic intravenous granuloma localized in the right cephalic vein. The imaging and pathological findings and the differential diagnoses are discussed.

摘 要:
A bone island represents a focus of mature compact bone within the cancellous bone, and it can be diagnosed based on characteristic clinical and radiologic features. The lesion is typically asymptomatic with a preference for the pelvis, femur, and other long bones. On radiographs, the lesion appears as an ovoid, round or oblong homogeneously dense and sclerotic focus in the cancellous bone. The characteristic features of this lesion are radiating bony streaks, known as thorny radiations or pseudopodia. Most bone islands are small, and the majority of these lesions measure from 0.1 to 2.0 cm. A giant bone island, defined as having a diameter greater than 2 cm, has been rarely reported in the English-language literature. We report here on a case of a giant bone island that measured 10 x 1.7 x 1 cm in the diaphysis of the right tibia in a 31-year-old man who complained of right lower leg pain for 3 weeks.
