Computer-assisted antetorsion control prevents malrotation in femoral nailing: an experimental study and preliminary clinical case series.
The effect of fluoroscopy-based navigation for femoral fracture reduction on the prevention of malrotation was examined in an experimental setting followed by a first case series. Eleven cadaver femurs were used. All femurs were reduced by closed methods. An optoelectronic navigation system was utilized to check for fragment reduction and alignment. Fluoroscopic control without navigation was used as the control group. The Six Sigma Analysis [offset capability index (C (pk)) = 1.3] was used to compare the probability of outliers of more than 15 degrees . In the clinical case series the same navigation tool was used in ten non-consecutive patients with femoral fractures. Torsional differences between both legs were measured postoperatively by CT scan. ⋯ IV.

Our clinical experience on calcaneal bone cysts: 36 cysts in 33 patients.
Solitary bone cysts are lesions of benign nature with fluid content. The frequent locations for these cysts are the proximal femur or humerus. Rarely, they may occur in locations such as the calcaneus, mostly in adults. We have reported the second largest case series of calcaneal bone cysts. ⋯ Simple bone cysts with the location of calcaneus are not a rare entity. According to our series, simple bone cysts have been shown to be typically located in the calcaneus bone in middle-aged patients in particular. Furthermore, in such patients, heel pain is considerably severe, which is a symptom to be kept in mind in differential diagnosis. Curettage and autogenous grafting is the successful method of treatment and it provides good results.

Mid-term outcome of GSB-III total elbow arthroplasty in patients with rheumatoid arthritis and patients with post-traumatic arthritis.
We reviewed the mid-term outcome of GSB-III semi-constrained total elbow arthroplasty (TEA) and compared the results of patients with rheumatoid arthritis (RA) and those suffering from post-traumatic arthritis (PTA). ⋯ The recommendation of TEA, including in patients with PTA, is supported.

Measurements of ligamentum flavum thickening at lumbar spine using MRI.
As the ligamentum flavum (LF) covers most of the posterolateral part of the lumbar spinal canal, its thickening can be attributed to the development of lumbar canal encroachment. Nevertheless, there have been few reports describing the natural history of the LF. ⋯ The following results were obtained. (1) LF thickness increased with age; however, the increments at L4-5 and L3-4 were larger than one at L2-3 and L5-S1. (2) At L4-5, LF was over 3.0 mm thick in patients in the 20-29 age bracket, and in many of them it was more than 3.5 mm thick. (3) All patients with a thickened LF at L2-3 (>3.0 mm) had very thick LFs at all spinal levels. (4) In elderly patients, there was no correlation between the thickness of LF and the decrease of the disc height. In this study, we concluded that thickening of LF at L4-5 had already started in patients in the 30-39 age bracket and that thickening of the LF was not the buckling of the LF into the spinal canal with disc degeneration. The thickness of LF at L2-3 may serve as an indicator of lumbar spinal canal stenosis at multiple levels.

Randomized Controlled TrialTreatment of lateral epicondilitis using three different local injection modalities: a randomized prospective clinical trial.
To determine the effectiveness of three different local injection modalities in the treatment of lateral epicondilitis. ⋯ In the treatment of lateral epicondilitis, combination of corticosteroid injections with peppering is more effective than corticosteroid injections or peppering injections alone and produces better clinical results.
