Assessment of Instability in Thoracolumbar Burst Fractures Using a New Bone Scan Scoring System.

: Unstable thoracolumbar burst fractures require surgical management as they can result in neurological deficits if left untreated. This study aimed to evaluate whether a new bone scan scoring system could accurately assess instability in thoracolumbar burst fractures. : Fifty-two patients with thoracolumbar burst fractures who underwent bone scans and magnetic resonance imaging prior to surgery between January 2015 and August 2017 at Ulsan University Hospital were selected for inclusion.

Comparison of clinical outcomes between arthroscopic subchondral drilling and microfracture for osteochondral lesions of the talus.

Purpose: The objectives of this study were to compare the clinical outcomes of the two common bone marrow stimulation techniques such as subchondral drilling and microfracture for symptomatic osteochondral lesions of the talus and to evaluate prognostic factors affecting the outcomes.

Methods: Ninety patients (90 ankles) who underwent arthroscopic bone marrow stimulation for small- to mid-sized osteochondral lesions of the talus constituted the study cohort. The 90 ankles were divided into two groups: a drilling group (40 ankles) and a microfracture group (50 ankles).

A comparative study of meniscectomy and nonoperative treatment for degenerative horizontal tears of the medial meniscus.

Background: It is still debated whether a degenerative horizontal tear of the medial meniscus should be treated with surgery.

Hypothesis: The clinical outcomes of arthroscopic meniscectomy will be better than those of nonoperative treatment for a degenerative horizontal tear of the medial meniscus.

Study Design: Randomized controlled trial; Level of evidence, 1.

Multicentric giant cell tumor in adolescents: three case reports.

The presentation of multicentric giant cell tumor in adolescents with an open physis is very rare. We report three cases of a multicentric giant cell tumor of the bone in adolescents, and a review of the literature is also presented.
