The purpose of this study was to investigate glenoid morphology and define the safe zone for protecting the suprascapular nerve baseplate screw during baseplate fixation in reverse shoulder arthroplasty (RSA) in a Chinese population. ⋯ Glenoid size and the safe zone for screw fixation during RSA were characterized in a Chinese population. Careful consideration of baseplate fixation and avoidance of suprascapular nerve injury are important for improved clinical outcome.

The goal was to evaluate the clinical outcomes, quality of reduction and complications of pelvic fractures treated by minimally invasive stabilisation of posterior pelvic ring instabilities with pedicle screws connected to a transverse rod. ⋯ Minimally invasive stabilisation of posterior-pelvic-ring instabilities with pedicle screw connected to a transverse rod may be a good alternative to sacroiliac screw fixation because it is quick, safe and associated with a good functional outcome; thus being a useful option in patients who do not qualify for sacroiliac screw fixation.

Comparative Study
A biomechanical comparison of different fixation techniques for fractures of the acetabular posterior wall.
This study aimed to evaluate the biomechanical stability of different fixation techniques for fractures of the acetabular posterior wall. The hypothesis was that a reconstruction plate, combined with compression screw fixation and a plate placed lateral to the screws, would achieve a higher peak load to failure and stiffness and reduced gapping during cycle loading than other fixation techniques. ⋯ Fixation using a reconstruction plate and compression screws placed lateral to the screws may address acetabular posterior wall fractures in a more appropriate manner than techniques using only plates or screws. However, this study does not provide evidence to support the fact that placing the plate lateral to the screws is advantageous in comparison with other techniques.

The influence of chondromalacia patellae (CMP) on post-operative anterior knee pain (AKP) following total knee arthroplasty (TKA) remains controversial, and few studies have focused on the relationship between them. The purpose of this study was to determine whether different CMP grades affect the incidence of AKP after TKA without patellar resurfacing. ⋯ The findings may suggest no relevant influence of CMP grading on the incidence of AKP after TKA without patellar resurfacing.

We report the oncological and functional results of limb salvage for bone sarcomas involving the distal tibia using hybrid surgical technique of resection arthrodesis by bone transport then plating. ⋯ In carefully selected patients with primary distal tibial sarcomas, this hybrid method can effectively eliminate tumor lesion, reconstruct function, and shorten the length of wearing an external fixator by a meticulous conversion to internal fixator.
