Pedobarographic evaluation of five commonly used orthoses for the lower extremity.
Orthoses are designed to achieve immobilization or off-loading of certain regions of the foot. Yet, their off-loading capacity for the specific regions has not yet been studied. Therefore, the aim of this study was to analyze the plantar pressure distribution of five commonly applied orthoses for foot and ankle in a healthy population. ⋯ This is the first study to investigate the specific off-loading capacities of different orthoses for specific foot regions in a healthy collective. The knowledge of absolute and relative load shifts for the different orthoses is of fundamental interest for targeted clinical decision-making of physicians.

The pre-diseased coronal alignment can be predicted from conventional radiographs taken of the varus arthritic knee.
The concept of restoring the constitutional, pre-diseased alignment has gained lots of interest among knee surgeons. Previous attempts to use the contralateral limb to bridge the gap between the arthritic and the constitutional alignment were unsuccessful. We investigated the usability of a mathematical formula to predict the constitutional (pre-diseased) coronal alignment once arthritis has occurred. It is our hypothesis that by using the KL grade, CPAK classification and four radiographic measurements of the arthritic knee, the pre-diseased coronal alignment could be predicted. ⋯ Using the KL grade, CPAK classification and four radiographic measurements of the arthritic knee, the pre-diseased coronal alignment can be predicted in 80% of the varus knees with an accuracy of ≤ 0.5°. The predicted HKA (HKAPRED) can be very useful in the current and future clinical practice.

Is biceps tenodesis necessary when performing arthroscopic rotator cuff repair in patients older than 55 years?
In patients with arthroscopic rotator cuff repair, tenotomy and tenodesis are the most performed surgical procedures for the biceps long head (BLH) pathologies. Controversy continues as to which surgical procedure provides better results. This study aimed to compare the clinical outcomes of tenotomy and tenodesis applied to the biceps long head in patients who underwent arthroscopic rotator cuff repair. ⋯ The effect of tenodesis versus tenotomy for BHL pathologies in patients who underwent arthroscopic rotator cuff repair was not significant for clinical scores, but bicipital groove tenderness and biceps muscle cramping were significantly higher in the tenodesis group.

Survival rates of different bearing surfaces with the same model of stem in total hip arthroplasty: predictive factors for revision surgery.
Few studies have examined the survival rates of total hip arthroplasty (THA) with the same femoral stem, and the predictive factors leading to the revision of stemmed metal-on-metal (MoM) THA remain unknown. We determined the long-term survival rate of stemmed MoM THA compared with that of metal-on-polyethylene (MoP) bearing THA, the effect of head size and cup placement angle on revision rate, and predictors of revision. ⋯ Stemmed MoM THA has a very low survival rate and should be used with caution. It is important to monitor the patient's symptoms and perform appropriate imaging to ensure timely revision.

Does mechanism of injury impact the outcome of operative fixation of geriatric proximal humerus fractures.
The purpose of this study is to determine the effects of energy mechanism on outcomes following repair of proximal humerus fractures (PHF) in the middle aged and geriatric population. ⋯ Energy and mechanism demonstrates similar outcomes in operatively treated proximal humerus fractures. These factors should not play a role in decisions for surgery in these patients and can help guide patient expectations.
