Outcomes of Open Arthrotomy and Arthroscopic Surgery for Primary Synovial Chondromatosis of the Hip: A Comparative Study With Propensity Score Matching.

Background: Despite the widespread use of arthroscopic surgery for hip synovial chondromatosis, its postoperative outcomes remain uncertain. A head-to-head comparison between open arthrotomy and arthroscopic surgery is lacking.

Purpose: To compare the treatment outcomes of open arthrotomy, particularly with surgical dislocation, and arthroscopic surgery for hip synovial chondromatosis.

Risk factors of revision operation and early revision for adjacent segment degeneration after lumbar fusion surgery: a case-control study.

Background Context: Adjacent segment degeneration (ASD) following lumbar fusion operation is common and can occur at varying timepoints after index surgery. An early revision operation for ASD, however, signifies a short symptom-free period and might increase the risk of successive surgeries.

Purpose: We aimed to elucidate the overall risk factors associated with revision surgeries for ASD with distinct attention to early revisions.

Changes in flexor pollicis longus tendon cross-sectional dimensions after A1 pulley release for paediatric trigger thumb.

In this study, 30 patients with unilateral paediatric trigger thumb were examined with measurements taken within 1 month before surgery, and at 3 months after surgery. We measured the dorsal-palmar (DP) diameter, radioulnar (RU) diameter and cross-sectional area (CSA) of the flexor pollicis longus (FPL) tendon at two sites: just proximal to the A1 pulley and underneath the A1 pulley using ultrasonography. Following surgical A1 pulley release, the DP diameter, RU diameter and CSA of the FPL tendon just proximal to the A1 pulley significantly decreased from 2.
