A comparative study of volar locking-plate fixation with corticocancellous and pure cancellous bone grafts for scaphoid nonunion with dorsal intercalated segmental instability secondary to scaphoid humpback deformity.

Introduction: Bone grafts for scaphoid nonunion with deformity include cortcicocancellous or pure cancellous bone grafts. This study compared the outcomes between two types of bone grafts when employing a volar locking-plate in patients with scaphoid nonunion with dorsal intercalated segmental instability (DISI).

Patients And Methods: This retrospective study included 34 patients with scaphoid nonunion and DISI due to humpback deformity treated between March 2017 and January 2022.

The SPECT/CT Evaluation of Compartmental Changes after Open Wedge High Tibial Osteotomy.

Purpose: The purpose of this study was to evaluate compartmental changes using combined single-photon emission computerized tomography and conventional computerized tomography (SPECT/CT) after open wedge high tibial osteotomy (OWHTO) for providing clinical guidance for proper correction.

Materials And Methods: Analysis was performed using SPECT/CT from around 1 year after surgery on 22 patients who underwent OWHTO. Postoperative mechanical axis was measured and classified into 3 groups: group I (varus), group II (0°-3° valgus), and group III (>3° valgus).

Performance of antegrade suture passers according to tendon thickness.

Purpose: To determine the effect of tendon thickness on the needle penetration ability of four different designs of antegrade suture passers.

Materials And Methods: Four antegrade suture passers were tested: (a) ExpresSew II (Depuy Mitek Inc., Raynham, MA), (b) Arthrex Scorpion (Arthrex, Naples, FL), (c) Concept (Linvatec Corp, Largo, FL), and (d) ElitePass (Smith and Nephew Endoscopy, Andover, MA).

The influence of pain sensitivity on the symptom severity in patients with lumbar spinal stenosis.

Background: The symptom severity of back pain/leg pain is not correlated with the severity of degenerative changes and canal stenosis in lumbar stenosis. Considering the individual pain sensitivity might play an important role in pain perception, this discordance between the radiologic findings and clinical symptoms in degenerative lumbar stenosis might originate from the individual difference of pain sensitivity for back pain and/or leg pain.

Objective: To determine the relationship among the clinical symptoms, radiologic findings, and the individual pain sensitivity in the patients with degenerative lumbar spinal stenosis.

Impact of the attainment of current recommended low-density lipoprotein cholesterol goal of less than 70 mg/dl on clinical outcomes in very high-risk patients treated with drug-eluting stents.

Objective: We sought to evaluate whether the attainment of low-density lipoprotein cholesterol (LDL-C) goal of less than 70 mg/dl would affect clinical outcomes in Korean patients treated with drug-eluting stents (DES).

Background: The current cholesterol guideline has strongly recommended reducing LDL-C to less than 70 mg/dl as the goal of therapy for very high-risk patients.

Methods: From 2003 to 2006, a total of 1347 very high-risk patients were treated with DES.
