ReviewSalvage of recurrence after failed surgical treatment of hallux valgus.
Recurrence of the deformity is unfortunately a common occurrence following surgical treatment of hallux valgus. The underlying reason for recurrence is multifactorial and includes surgeon's factor, patient's factor, and deformity components that were not addressed at the index procedure. ⋯ Successful treatment requires understanding the underlying reason for the failure of initial treatment and correcting bony alignment, restoring the joint congruity, and balancing soft tissues. We present an algorithmic approach to revision hallux valgus surgery.

Clinical TrialExtracorporeal shock wave therapy in early osteonecrosis of the femoral head: prospective clinical study with long-term follow-up.
Extracorporeal shock wave therapy (ESWT) may exert beneficial effects in avascular necrosis of femoral head (AVNFH). ⋯ ESWT in ARCO stages I and II may help to prevent progression of the area of avascular necrosis and manage pain.

Clinical and radiographical results of 179 thrust plate hip prostheses: 5-14 years follow-up study.
The thrust plate hip prosthesis (TPP) is a bone-reserving prosthesis for cementless fixation at the metaphysis of the proximal femur. We retrospectively evaluated the results of 162 patients (179 hips) who underwent hip arthroplasty using TPP. ⋯ The middle-term results of the TPP were satisfactory if the indication for the TPP and the operative procedure were appropriate. The TPP is a useful and safe prosthesis for relatively young patients with not only osteoarthritis of the hip but also osteonecrosis of the femoral head.

Clinical TrialPrecision of Ci-navigated extension and flexion gap balancing in total knee arthroplasty and analysis of potential predictive variables.
The aim of this study was to evaluate the accuracy of final limb alignment and flexion-extension and medial-lateral gap balancing in computer navigated total knee arthroplasty and to analyze various possible predictive variables that may affect the gaps in computer navigated knee arthroplasty. ⋯ Computer-assisted navigated total knee replacement allows for accurate gap balancing that is not dependent on the various pre- and intraoperative factors mentioned, including age, sex, Range of motion preoperative deformity and grade of osteoarthritis. The Ci-calculated and verified tibial, and femoral cuts are the only possible factors affecting the extension gap.

Survivorship of second-generation metal-on-metal primary total hip replacement.
Second generation metal-on-metal total hip replacements (THR) were introduced in the late 1980s and various studies reported conflicting data on their outcome. ⋯ As there was no superior probability of survival, and there have been concerns on putative local and systemic toxicity of metal debris, the use of second-generation metal-on-metal articulations for primary THR remains moot.
