Morphometric analysis of the proximal thoracic pedicles in Lenke II and IV adolescent idiopathic scoliosis: an evaluation of the feasibility for pedicle screw insertion.

Purpose: Pedicles on the concave side of the proximal thoracic (PT) curve in adolescent idiopathic scoliosis (AIS) patients with Lenke II and IV deformities tend to be narrow and dysplastic, making pedicle screw (PS) insertion challenging. The aim of this study was to evaluate the feasibility for PS placement in these patients using pedicle chord length, diameter, and channel morphology.

Methods: In this retrospective study, 56 consecutive AIS patients with Lenke II or IV curves who underwent instrumented posterior spinal fusion (PSF) were studied.

Strategy for Selective C-F and C-C Formations from Organoplatinum Complexes.

By changing the parameters of fluorination reaction of bisaryl-platinum(II) complexes, each possible competitive pathway of Ar-Ar and Ar-F formation can be selectively controlled. It was discovered that steric hindrance, type of fluorinating reagent, and temperature of reaction are determinants for Ar-F vs Ar-Ar bond formation pathway from bisaryl-fluoro-platinum(IV) complexes. The combination of bulky ligands such as mesityl with Selectfluor at RT leads to Ar-F bond formation in the presence of possible Ar-Ar formation.

Preoperative Fatty Infiltration of the Teres Minor Negatively Affects Postoperative Outcomes in Patients With Rotator Cuff Pathology.

Background: The teres minor is a critical component of the rotator cuff and serves as one of the few external rotators of the humerus. Information is lacking regarding the effect of teres minor atrophy in isolation and in the setting of concomitant full-thickness rotator cuff tears on outcomes in patients undergoing rotator cuff surgery.

Purpose: To investigate the effect of preoperative teres minor fatty infiltration on postoperative clinical outcomes in patients with and without full-thickness rotator cuff pathology.

Long-Term Outcomes for Arthroscopic Thermal Treatment for Scapholunate Ligament Injuries.

 Arthroscopic electrothermal treatment of low-grade Geissler's scapholunate interosseous ligament (SLIL) tears has shown clinical benefit at short-term follow-up.  This study aims to evaluate the long-term functional outcomes in patients undergoing this treatment.  A retrospective review of all patients treated between 2005 and 2013 was performed.

Long-Term Outcomes of All-Arthroscopic Pre-Tied Suture Device Triangular Fibrocartilage Complex Repair.

 A pre-tied suture device has been utilized for all-arthroscopic peripheral triangular fibrocartilage complex (TFCC) repairs with promising early clinical results.  The purpose of this study was to evaluate long-term functional outcomes of these repairs.  A retrospective review of patients undergoing arthroscopic TFCC repair was performed.
