Stability changes after cryosurgery in long tubular bones in correlation to histological results: an animal trial.
Pathologic bone fractures in cryosurgery of bone tumors have been described in literature. This study utilizing a sheep model should prove the possible reduction of potential fracture while using a new miniature cryoprobe minimizing tissue damage and providing accurate control of the ablation process. Furthermore, postoperative histological changes should be investigated and the results correlated with the stability trials. ⋯ A thorough control of the freezing process and the low iatrogenous weakening of the bone due to placing the probe when modern miniature cryoprobes are used can minimize the risk of pathological postoperative fractures. However, at least 2 months after operation there is histological proof of bone healing with appropriate reduction of bone stability, which should be considered for the clinical application of this new technique.

Randomized Controlled Trial Comparative StudyComparison of ultrasound-, palpation-, and scintigraphy-guided steroid injections in the treatment of plantar fasciitis.
The aim of the study was to compare the efficacies of steroid injections guided by scintigraphy, ultrasonography, and palpation in plantar fasciitis. ⋯ The ug, pg, and sg injections were effective in the conservative treatment of plantar fasciitis. We are of the opinion that steroid injections should be performed, preferably with palpation or ultrasonographic guidance.

Comparative StudyContrast-enhanced MR imaging of subchondral insufficiency fracture of the femoral head: a preliminary comparison with that of osteonecrosis of the femoral head.
Subchondral insufficiency fracture of the femoral head (SIF) may be confused with osteonecrosis of the femoral head (ON) due to clinical and imaging similarities. ⋯ These results suggest that the presence of contrast enhancement in the segment proximal to the low-signal intensity band in the femoral head may serve as a supplemental diagnostic measure for the differentiation of SIF from ON.

Comparative StudyCentenarians versus patients within the most frequent age range for hip fractures: transfusion practice.
Descriptive retrospective review to compare transfusion among centenarians operated for a hip fracture with a control group within the "typical" age range for that surgery. ⋯ Despite intuitive beliefs, centenarians had results similar to those of the younger population: only a higher complication rate could be proved. Larger samples and prospective studies might be needed to confirm the trends noted.

Volar fixed-angle plate osteosynthesis of unstable distal radius fractures: 12 months results.
With an incidence of about 2-4 per 1,000 residents per year, the distal radial fracture is the most common fracture in the human skeleton. The introduction of fixed-angle plate systems for extension fractures at the radius was evaluated in a prospective study performed at our hospital after selection and acquisition of a new system. The focus of our interest was whether a secondary loss of reduction can be avoided by this plating system. ⋯ Fixed-angle plate osteosynthesis at the distal radius signifies a significant improvement in the treatment of distal radial fractures in terms of restoration of the shape and function of the wrist. The technically simple palmar access, with a low rate of complications, allows exact anatomical reduction of the fracture. The multidirectional fixed-angle system we used provides solid support for the joint surface even in osteoporotic bone and allows simple subchondral placement of screws with sustained retention of the outcome of reduction. Secondary correction loss can be avoided by this procedure. Early mobilisation can be achieved and is recommended.
