Extracorporeal shockwave therapy for the treatment of scaphoid delayed union in a tennis player: A case report.

Operative procedures are considered the gold standard when treating delayed union or non-union of the scaphoid despite their considerable complexity and the risk of intraoperative complications. Although extracorporeal shockwave therapy has been reported as a non-invasive treatment option for non-union cases, only a few papers on delayed union or non-union of the scaphoid have been published. A 57-year-old man with delayed union of a scaphoid fracture was treated with extracorporeal shockwave therapy and showed complete bone healing with promising results two months after the start of treatment without undergoing surgery.

Unrepaired lateral meniscus tears lead to remaining pivot-shift in ACL-reconstructed knees.

Purpose: To compare the postoperative rotatory knee laxity between ACL-reconstructed knees with different meniscus treatments using an electromagnetic pivot-shift measurement.

Methods: Forty-six patients with unilateral ACL reconstructions were enrolled (21 males/25 females, 25 ± 12 y.o.

No difference in postoperative rotational laxity after ACL reconstruction in patients with and without anterolateral capsule injury: quantitative evaluation of the pivot-shift test at 1-year follow-up.

Purpose: To compare rotational laxity in anterior cruciate ligament (ACL)-reconstructed knees retrospectively with and without concomitant anterolateral capsule (ALC) injury confirmed by magnetic resonance imaging (MRI) prior to ACL reconstruction.

Methods: Sixty-two ACL-reconstructed knees (26 men, 36 women; median age 20 (range 13-59)) were included. Pivot-shift test was performed before ACL reconstruction and 1 year postoperatively under anesthesia with both clinical grading and quantitative measurement simultaneously.

Quantification of myocardial blood flow with C-hydroxyephedrine dynamic PET: comparison with O-HO PET.

Background: C-hydroxyephedrine (HED) PET has been used to evaluate the myocardial sympathetic nervous system (SNS). Here we sought to establish a simultaneous approach for quantifying both myocardial blood flow (MBF) and the SNS from a single HED PET scan.

Methods: Ten controls and 13 patients with suspected cardiac disease were enrolled.

Navigation-based tibial rotation at 90° of flexion is associated with better range of motion in navigated total knee arthroplasty.

Purpose: In clinical practice, people with better femorotibial rotation in the flexed position often achieve a favourable postoperative maximum flexion angle (MFA). However, no objective data have been reported to support this clinical observation. In the present study, we aimed to investigate the correlation between the amount of intraoperative rotation and the pre- and postoperative flexion angles.
