Quantitative anatomic basis of antegrade lag screw placement in posterior column of acetabulum.
Lag screw fixation has been recommended for treatment of acetabular and pelvic fracture for several years. The aim of the present study was to determine the projection of the axis of the posterior column on the inner table of the iliac wing in the supra-acetabular region. ⋯ The present study describes a safe anchor path of antegrade lag screw fixation in the posterior column. Insertion of the lag screws of adequate length is possible in the posterior column along its functional axis.

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.
