Revision of failed acetabular components utilizing a cementless oblong cup: an average 9-year follow-up study.
Failure of acetabular components often leads to bone loss with extensive elongated defects in the surrounding bone. In these cases, reconstruction is challenging and stable fixation of the revision implant difficult. The use of an oblong cup has been described as an option for acetabular reconstruction in such revisions. We report the first long-term results obtained with this implant to date. ⋯ This 12-year clinical study demonstrates that the LOR cup offers a successful concept for the revision of failed acetabular components that also promotes the biological reconstruction of bony defects. Compared with other methods with similarly long follow-ups, our long-term results prove this procedure has a very low rate of revision and aseptic implant failure.

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.

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.

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.

The prevalence of absence of the palmaris longus: a study in Turkish population.
It is well known that there is a wide variation in the reported prevalence of the palmaris longus (PL) absence in different ethnic groups. This prospective study was conducted to determine the prevalence of absence of PL and correlate it with gender and body side in Turkish population. ⋯ Mishra's second test which involves resisted abduction of the thumb, may be better in demonstration of the PL where the muscle was feebly developed, particularly in women.
