Functional and radiological outcome of distal radius fractures stabilized by volar-locking plate with a minimum follow-up of 1 year.
Distal radius fractures (DRF) are the most common fractures of the upper extremities and incidence is expected to continue rising as life expectancy increases. Palmar locking plate stabilizing has since become the standard treatment for dorsally displaced DRF. Main aim of this study was to investigate correlation between radiological and clinical outcome in patients stabilized by palmar locking plate with a minimum follow-up of one year. ⋯ Stabilization of DRF by palmar angular stable locking plate is a safe form of treatment and results in a good clinical and radiological outcome with low complication rate. Ulnar variance showed a significant correlation to grip strength, QuickDASH and Mayo Score, but an unacceptable ulnar variance (> 2 mm) was not associated with a worse clinical important outcome. Age (< 65/> 65 years), gender and type of immobilization had no impact on the complication rate or in the final functional or radiological outcome.

Intraoperatively accurate limb alignment after opening wedge high tibial osteotomy can be lost by large knee joint line convergence angle during surgery.
The purpose of this study was to assess early postoperative loss of achieved correction and associated factors after opening wedge high tibial osteotomy (OWHTO). ⋯ This study demonstrated the early loss of achieved correction after OWHTO due to change of the JLCA, even if the accurate alignment is obtained intraoperatively.

Latarjet procedure for anterior shoulder instability: a 24-year follow-up study.
Different surgical techniques (open and arthroscopic) have been described for the treatment of post-traumatic recurrent anterior instability. The aim of the surgery is to restore when possible, normal shoulder anatomy by repairing the underlying pathology responsible for the instability. Sometimes other surgical techniques are indicated. The purpose of this retrospective study was to investigate the long-term clinical and radiographic results and complications of the open Latarjet procedure after a minimum follow-up of 24 years. ⋯ Level III; retrospective cohort comparison; treatment study.

Short stem humeral components in reverse shoulder arthroplasty: stem alignment influences the neck-shaft angle.
Shorter humeral reverse total shoulder arthroplasty (RTSA) stems may reduce stress shielding, however, potentially carry the risk of varus/valgus malalignment. This radiographic study's purpose was to measure the incidence of stem malalignment and thus the realized neck-shaft angle (NSA). The hypothesis was that malalignment of the stem is a frequent postoperative radiographic finding. ⋯ Level IV, retrospective study.

The effect of coronal splits on the structural stability of bi-condylar tibial plateau fractures: a biomechanical investigation.
Surgical treatment of bi-condylar tibial plateau fractures is still challenging due to the complexity of the fracture and the difficult surgical approach. Coronal fracture lines are associated with a high risk of fixation failure. However, previous biomechanical studies and fracture classifications have disregarded coronal fracture lines. ⋯ Coronal articular fracture lines substantially affect the mechanical response of tibia implant structures specifically on the medial side. With this in mind, utilizing a clinically relevant fracture model for biomechanical evaluations regarding bi-condylar tibial plateau fractures is strongly recommended.
