Background: In epilepsy stigma, certain perceptions are culturally dependent and greatly influence a person's attitudes. Hence, we aimed to explore the perceptions associated with attitudes toward epilepsy in various urban subpopulations.

Method: This is a mixed-method study employing the Public Attitude Toward Epilepsy (PATE) scale as the quantitative measure, followed by a semi-structured interview.

Objective: The incidence of postoperative shoulder imbalance following posterior spinal fusion (PSF) is still high in Lenke 1 curves despite following current treatment recommendations for upper instrumented vertebra (UIV) selection. The objective of this retrospective study was to identify differences in preoperative shoulder balance and to report the surgical outcome of two subtypes of Lenke 1 curves (flexible vs stiff) in patients with adolescent idiopathic scoliosis (AIS).

Methods: The authors grouped patients' curves as Lenke 1-ve (flexible) when their preoperative proximal thoracic side bending (PTSB) Cobb angle was < 15° and as Lenke 1+ve (stiff) when the PTSB Cobb angle was 15°-24.

Study Design: Retrospective study.

Objective: The primary objective of this study was to assess the conformity of the radiological neck and shoulder balance parameters throughout a follow-up period of more than 2 years.

Summary Of Background Data: Postoperative shoulder and neck imbalance are undesirable features among Adolescent Idiopathic Scoliosis patients who underwent Posterior Spinal Fusion.

Study Design: Retrospective study.

Objective: This study looked into whether crossbar can reliably measure Upper Instrumend Vertebra (UIV) tilt angle intraoperatively and accurately predict the UIV tilt angle postoperatively and at final follow-up.

Summary Of Background Data: Postoperative shoulder imbalance is a common cause of poor cosmetic appearance leading to patient dissatisfaction.

Study Design: Retrospective study of prospectively collected data.

Objective: To analyze the incidence and the patterns of medial and lateral shoulder discordance among Lenke 1 and 2 patients.

Summary Of Background Data: Postoperative shoulder imbalance (PSI) is still common in Lenke 1 and 2 adolescent idiopathic scoliosis (AIS).

Background Context: In Lenke 1C and 2C curves, the choice between selective thoracic fusion (STF) versus non-selective thoracic fusion as the optimal surgical treatment is controversial.

Objective: This study aimed to assess the radiological and clinical outcome of patients with Lenke 1C and 2C curves treated with STF.

Study Design: This is a retrospective study.
