Subtalar arthroscopy and fluoroscopy in percutaneous fixation of intra-articular calcaneal fractures.
Percutaneous fixation of intra-articular calcaneal fractures is traditionally assisted only by intraoperative fluoroscopy. Previous studies have demonstrated that the additional use of subtalar arthroscopy in anatomical reduction of the posterior calcaneal facet of the subtalar joint for less complex calcaneal fractures yielded positive results up to 2-year follow-up. This study aims to investigate long-term outcomes of these patients using similar evaluation parameters. We hypothesized that this novel technique with dual-imaging can provide sustainable, long-term benefits with good functional outcomes and significant restoration of the Bohler's angle. ⋯ Subtalar arthroscopy with intraoperative fluoroscopy in anatomical reduction of the posterior calcaneal facet of the subtalar joint is most useful in Sanders type II, AO-OTA 83-C2 fractures with excellent functional outcomes and good preservation of the corrected Bohler's angle on long-term follow-up.

The relationship between radiological alignment of united distal radius fractures and functional and patient-perceived outcomes in elderly patients.
The purpose of this study was to investigate the relationship between radiological alignment and functional outcomes including strength, range of motion (ROM), and disabilities of the arm, shoulder, and hand (DASH) and patient-rated wrist evaluation (PRWE) scores in elderly patients with united distal radius fractures. ⋯ This study suggests that minor deformities of the distal radius following distal radius fractures treated with either operative or nonoperative treatment are unlikely to be clinically relevant and have no impact on patient perceived outcomes for elderly patients.

A new technique for arthroscopic reduction and fixation of displaced tibial intercondylar eminence fractures, using suture anchor and EndoButton system.
The study aims to describe a less invasive technique for displaced tibial intercondylar eminence fractures, using only one bone tunnel with suture anchor and EndoButton system. ⋯ The study demonstrated that the procedure is safe and effective, which can be another option for tibial intercondylar eminence fractures.

Prediction of height increment using preoperative radiological parameters following selective thoracic fusion with alternate-level pedicle screw construct in Lenke 1 and 2 adolescent idiopathic scoliosis patients.
This study aims to derive a formula to predict post-operative height increment in Lenke 1 and Lenke 2 adolescent idiopathic scoliosis (AIS) patients using preoperative radiological parameters. ⋯ The proposed formula of increase in height (cm) = (0.09 × preoperative MT Cobb angle) - (0.04 × FB Cobb angle) - 0.5 could predict post-operative height gain to within 5 mm accuracy in 51% of patients, within 10 mm in 70% and within 15 mm in 86% of patients.

To determine whether supplementary tibial graft fixation with a staple is routinely necessary for anterior cruciate ligament (ACL) reconstructions. ⋯ Our study showed that supplementary tibial graft fixation with a staple is not routinely necessary for ACL reconstructions. It confers no additional benefits when compared with the use of biointerference screw alone for tibial graft fixation but may increase the risks of symptomatic hardware.
