Is Intraoperative CT Navigation feasible for excision of osteoid osteoma in the appendicular skeleton? - Retrospective analysis of 58 cases.

Background: The use of intraoperative CT navigation to manage osteoid osteoma is not common. We report our experience managing osteoid osteoma in the appendicular skeleton using an intraoperative AIRO CT navigation system.

Materials & Methods: Between May 2013 and December 2022, 59 patients underwent Navigation-assisted excision of osteoid osteoma in the appendicular skeleton.

A Prospective, Multicenter Study of Developmental Dysplasia of the Hip: What Can Patients Expect After Open Reduction?

Background: Although there are several predominantly single-center case series in the literature, relatively little prospectively collected data exist regarding the outcomes of open hip reduction (OR) for infantile developmental dysplasia of the hip (DDH). The purpose of this prospective, multi-center study was to determine the outcomes after OR in a diverse patient population.

Methods: The prospectively collected database of an international multicenter study group was queried for all patients treated with OR for DDH.

Unicameral Bone Cysts: Review of Etiopathogenesis and Current Concepts in Diagnosis and Management.

Objective: This article aims to review the epidemiology, etio-pathogenesis and updates in clinical diagnostics and management of unicameral bone cysts (UBC).

Methods: A computerized literature search using Cochrane database of systematic reviews, EMBASE and PubMed was performed. MeSH (Medical Subject Headings) terms used in searches included the following sub-headings: "unicameral bone cyst", "epidemiology", "etiology", "pathogenesis", "diagnosis", "management" and "surgery".

Anterior Physeal Separation of Distal Humerus: Report of a Rare Case with Review of Literature.

Background: Distal humeral physeal separation is a rare injury and often missed during the initial presentation. They are usually associated with birth trauma or child abuse. These fractures are often misdiagnosed as infection or dislocation.

Perspectives and Consensus among International Orthopaedic Surgeons during Initial and Mid-lockdown Phases of Coronavirus Disease.

With a lot of uncertainty, unclear, and frequently changing management protocols, COVID-19 has significantly impacted the orthopaedic surgical practice during this pandemic crisis. Surgeons around the world needed closed introspection, contemplation, and prospective consensual recommendations for safe surgical practice and prevention of viral contamination. One hundred orthopaedic surgeons from 50 countries were sent a Google online form with a questionnaire explicating protocols for admission, surgeries, discharge, follow-up, relevant information affecting their surgical practices, difficulties faced, and many more important issues that happened during and after the lockdown.

Pediatric Trigger Thumb: Congenital or Developmental? A Unique Case Report.

Pediatric trigger thumb is the new terminology for the so-called congenital trigger thumb. This change in appellation was suggested based on recent knowledge acquired through prospective studies of a large number of newborns for the presence of trigger thumb at birth across many centers. In this background, we came across a newborn with trigger thumb which was diagnosed right after birth, putting aside all theories of nonexistence of congenital trigger thumb.

"Sliding angulation osteotomy": preliminary report of a novel technique of treatment for chronic radial head dislocation following missed Monteggia injuries.

Purpose: Neglected anterior radial head dislocation in type I Monteggia lesions leads to restriction of movement, deformity and instability of the affected elbow. If left untreated this leads to a painful arthritic elbow due to secondary degenerative changes. This is a difficult problem to manage and many intra-articular, extra-articular and combined procedures have been described with variable results.

Is the acetabulum retroverted in slipped capital femoral epiphysis?

Background: Recent biplanar radiographic studies have demonstrated acetabular retroversion and increased superolateral femoral head coverage in hips with slipped capital femoral epiphysis (SCFE), seemingly divergent from earlier CT-based studies suggesting normal acetabular version.

Question/purposes: We therefore asked: Are there differences in (1) acetabular version at the superior ¼ of the acetabular dome (AV(sup)), (2) acetabular version at the center of the femoral head (AV(cen)), and (3) superolateral femoral head coverage (lateral center-edge angle [LCEA]) among affected SCFE hips, unaffected hips, and normal controls?

Methods: We identified 32 patients with SCFE who underwent CT between 2007 and 2012. Twenty-three met our inclusion criteria.
