Untreated scaphoid nonunion as a rule results in subsequent scaphoid nonunion advanced collapse (SNAC) wrist. While reconstructive treatment of the scaphoid in association with resection of the styloid process of the radius is still promising in stage I SNAC wrist, salvage procedures are available for higher degrees of SNAC wrist to reduce pain and to preserve the function of the wrist. Denervation, proximal row carpectomy and partial wrist fusion maintain wrist mobility. Total wrist arthrodesis and total wrist arthroplasty are salvage procedures in cases of panarthritis or failed motion-preserving procedures.

Patellar fractures are a relatively rare entity with an prevalence of 1%. Preoperative computed tomography has gained a significant role as a diagnostic tool for patellar fractures in recent years. It enables an exact assessment of the fracture and helps in the decision making for the correct treatment procedure. ⋯ In this context, the results of angle stable plate fixation are promising in terms of functional outcome and lower complication rates. The proven tension band fixation using K‑wires or cannulated screws continues to be widespread in clinical practice and retains significance for simple patellar fractures. The use of polyethylene thread material instead of steel wire has shown advantages in biomechanical studies but the clinical application is more restrained.

Radial head fractures are the most frequent fractures of the elbow joint in adults. For Mason type II fractures without concomitant injuries favorable results have been shown with operative and conservative management. There is insufficient evidence concerning elbow joint stability after conservative treatment compared to open reduction and internal fixation (ORIF). ⋯ Both conservative management and operative treatment had a good functional outcome. Operative treatment showed a positive tendency concerning radiological and functional outcome without statistical significance.

Approximately 7-10% of all emergency department patients are diagnosed with distortion of the upper ankle joint. A dislocation of the upper ankle joint without fracture is described in the literature as being very rare. ⋯ We report the course, treatment and results 12 months after trauma of a posteromedial first-degree open dislocation of the upper ankle joint without fracture. To our knowledge, there is no record of this pathology mentioned in the German language literature.
