Mid to long-term results of open acromioclavicular-joint reconstruction using polydioxansulfate cerclage augmentation.
There is still controversy about the optimal operative treatment of acromioclavicular (AC)-joint dislocations. However, in the current literature, only few studies are available on mid- to long-term results of different stabilization methods. This retrospective study presents the clinical and radiographical results after open reduction and stabilization of AC-joint dislocations using polydioxanesulfate (PDS) cerclage augmentation. ⋯ Treatment of AC-joint dislocation using PDS cerclage augmentation leads to good to excellent clinical results. However, mid- to long-term follow-up reveals a high incidence of radiographic signs of osteoarthritis of the AC-joint. Whether this is due to the surgical technique and could be reduced using other, more anatomical fixation techniques or whether the injury itself leads to these changes, need to be shown.

Stability changes after cryosurgery in long tubular bones in correlation to histological results: an animal trial.
Pathologic bone fractures in cryosurgery of bone tumors have been described in literature. This study utilizing a sheep model should prove the possible reduction of potential fracture while using a new miniature cryoprobe minimizing tissue damage and providing accurate control of the ablation process. Furthermore, postoperative histological changes should be investigated and the results correlated with the stability trials. ⋯ A thorough control of the freezing process and the low iatrogenous weakening of the bone due to placing the probe when modern miniature cryoprobes are used can minimize the risk of pathological postoperative fractures. However, at least 2 months after operation there is histological proof of bone healing with appropriate reduction of bone stability, which should be considered for the clinical application of this new technique.

We reviewed four patients diagnosed with a cortical desmoid lesion at the distal posterior medial femur. Each case reflects a clinical scenario that can be present. ⋯ Here, we present the specific imaging features in association with patients history and clinical findings facilitating establishment of correct diagnosis. Exact diagnosis is important in order to avoid unnecessary biopsy and complicated therapeutic strategies.
