BACKGROUND: The main aim of this systematic review and meta-analysis was to identify peer-reviewed scholarly journal articles reporting the significance of physiotherapy interventions in managing TMJ ankylosis. In addition, this study aimed to critically appraise the existing evidence on the prevalence and clinical presentation, physiotherapy intervention approaches, efficacy of physiotherapy interventions, adverse effects, and safety of physiotherapy interventions in TMJ ankylosis management...

BACKGROUND: Investigating the molecular biology underpinning the early-stage of traumatic temporomandibular joint (TMJ) ankylosis is crucial for discovering new ways to prevent the disease. This study aimed to explore the dynamic changes of transcriptome from the intra-articular hematoma or the newly generated ankylosed callus during the onset and early progression of TMJ ankylosis. METHODS: Based on a well-established sheep model of TMJ bony ankylosis, the genome-wide microarray data were obtained from samples at postoperative Days 1, 4, 7, 9, 11, 14 and 28, with intra-articular hematoma at Day 1 serving as controls...

This prospective cohort study examined the changes in airway area and soft tissue parameters following interpositional arthroplasty for temporomandibular joint (TMJ) ankylosis. Ten patients with TMJ ankylosis underwent surgery, and preoperative and postoperative skeletal and soft tissue measurements were obtained. A significant rise in soft tissue parameters was observed following surgery, although only minor changes in skeletal parameters were seen. The nasoropharyngeal area, oral area, soft palate area, and tongue area were examined...

Orthodontic cases requiring tooth extraction sometimes involve post-traumatic incisors. For adolescent cases in which trauma causes the maxillary unilateral incisors to be missing or have poor prognoses, it is worth considering these teeth as candidates for extraction, and this unusual approach is seldom reported in the literature. An adolescent patient with a missing maxillary left lateral incisor and an ankylosed maxillary left central incisor sought treatment for dental protrusion and crowding. An unusual orthodontic approach was used, which involved the extraction of the maxillary left central incisor and mandibular first premolars...

OBJECTIVE: Unilateral temporomandibular joint ankylosis with jaw deformity (UTMJAJD) may require simultaneous total joint prosthesis (TJP) reconstruction, sagittal split ramus (SSRO), and Le Fort I osteotomies. The purpose of this study was to evaluate outcomes in patients treated with these procedures. METHODS: Patients diagnosed UTMJAJD between 2016 and 2018 were selected for the study. Mandible-first procedure was performed after ankylosis release with TJP on the ankylosed side and SSRO on the contralateral side...

Three-dimensional (3D) printed models can improve the understanding of the structural anatomic changes in cases of temporomandibular joint ankylosis and pseudoankylosis leading to closed jaw locking. Their use in pre-surgical planning and intraoperative guidance has been reported, contributing to the predictability and success of these surgery procedures, which can be quite complex, especially in small animal patients. The use and production of 3D tools and models remain challenging and are so far limited to institutions with high (economical and human) resources...

BACKGROUND: Forced eruption of an impacted tooth usually requires surgical and orthodontic interventions to successfully bring the tooth into the dental arch. The clinical time required for a forced eruption is difficult to predict before treatment begins and success rates are affected by several factors before and after an eruption. This study was conducted to identify factors that affect the success of forced eruption, the duration of orthodontic treatment of impacted teeth, and the reasons for re-operation and forced eruption failure in a various teeth and cases...

Ankylosing spondylitis (AS) is a chronic inflammatory condition primarily affecting the axial bone and sacroiliac joints. Its etiology is complicated and involves genetic variables, demographic factors (age of onset, gender, ethnicity, family history), and environmental variables. It typically manifests in males in their third decade. Galen is credited with first recognizing it, according to historical traditions, but it was not until the 19th century that specific diagnostic criteria were developed. The human leukocyte antigen B27 (HLA-B27) variation, around 20% of the genetic risk, is currently the most significant gene associated with AS susceptibility...

OBJECTIVES: The purpose of this study is to assess the equivalency of MRI-based synthetic CT (sCT) to conventional CT for sacroiliac joint bony morphology assessment in children. METHODS: A prospective study was performed. Children who had (PET-)CT-scan underwent additional MRI. sCT-CT image quality was analyzed by two readers subjectively overall, semi-quantitatively in terms of cortical delineation, joint facet defects, growth plate fusion, ossified nuclei, lumbosacral transitional anomaly, and bony bridges, and quantitatively for disc space height, spinal canal width, and sacral vertebrae width and height...

The aim of this study is to present a sequential strategy of soft-tissue, non-osteogenic distraction with a novel device, followed by microvascular bony reconstruction for severe cases of mandibular hypoplasia. The case of a 21-year-old woman with Goldenhar syndrome is presented, whose mandible remained severely hypoplastic despite previous attempts at distraction and was not suitable for further osteogenic distraction. Soft tissue deficiency and pin track scarring prevented free fibular transfers. A personalized distractor, anchored to the cranium and the mandibular symphysis, was designed to expand the soft tissues while allowing for physiological temporomandibular joint (TMJ) movement without compression forces...

The primary aim of this study was to investigate whether patients with end-stage temporomandibular joint (TMJ) disease treated with gap arthroplasty with temporalis interpositional flap (GAT) had improved maximal interincisal opening (MIO) and TMJ pain in a long-term perspective. All patients with severe osteoarthritis, or fibrous or bony ankyloses, and subjected to GAT between 2008 and 2015 were included. The criteria of treatment success were TMJ pain VAS score ≤4 and MIO ≥30 mm. Reoperation was considered as a failure...

BACKGROUND: Severe heterotopic ossification (grades III and IV) after total hip arthroplasty (THA) over the last 25 years requiring excision is very uncommon. We performed a systematic review of the literature and reported a new case series with operative treatment after primary uncemented THA. METHODS: A systematic review identified papers describing patients who had excision of heterotopic ossification (HO) after THA performed after 1988. Concepts of hip arthroplasty, heterotopic ossification, and surgical excision were searched in MEDLINE, Embase, and Scopus from database inception to November 2022...

Total hip arthroplasty remains the treatment of last resort in inflammatory coxarthritis, where joint destruction is bilateral as well as the treatment which must be bilateral. We present in this work the experience of our orthopaedic department with a series of five cases (10 hips) operated for total hip arthroplasty. the first particularity observed in this series is the abnormal bone fragility present in 55% of the cases. For this reason, we had two other intraoperative complications that are related to this bone fragility, during the preparation of the acetabulum, we had a destruction of the medial wall by the burr that went unnoticed intraoperatively and was discovered during the patient's recovery from acute ischemia secondary to the burr, which led to an extensive rupture of the common femoral vein and partial sectioning of the common femoral artery...

BACKGROUND: Phosphorous necrosis of the jaw (PNJ) exhibits similar clinical and pathological features as medical-related osteonecrosis of the jaw (MRONJ). This study aims at comparing the similarities and differences between PNJ and MRONJ regarding pathological features and to provide a theoretical basis for the clinical diagnosis and management of PNJ. MATERIAL AND METHODS: A retrospective analysis was conducted to assess clinical differences among 38 PNJ patients and 31 MRONJ patients, who were diagnosed and treated between January 2009 and October 2022...

INTRODUCTION: After third molars, canines are the teeth most commonly affected by displacement and impaction. Although orthodontic surgical treatment represents the standard method for realignment of canines, autotransplantation (autoTX) functions as the second-line therapy if orthodontic alignment does not succeed in treating impaction and severe displacement. This retrospective cohort study aimed to identify clinical predictors for postoperative survival and endodontic treatment needs after autoTX of severely displaced and impacted canines...

Ankylosing spondylitis (AS) is a chronic inflammatory arthritic disease that primarily affects the axial skeleton, and its association with the secondary development of osteoarthritis (OA) in peripheral joints, particularly the hips, is increasingly recognized. This case report elucidates the diagnostic and therapeutic challenges encountered in a patient with bilateral hip osteoarthritis secondary to AS. The patient's medical history included AS and a failed attempt at core decompression of the left hip joint...

Temporomandibular joint (TMJ) ankylosis leads to mandibular micrognathia that severely collapses the upper airway causing obstructive sleep apnoea (OSA), resulting in deterioration and compromise in the quality of life (QoL) of patients. In this study, we aimed to calculate airway volume changes, apnoea-hypopnoea index (AHI), and improvement in quality of life before and after distraction osteogenesis (DO). Fourteen Patients with OSA secondary to TMJ ankylosis at a mean (SD) age of 17.5 (5.43) years were enrolled in this prospective study...

Ankylosing spondylitis (AS) is a chronic inflammatory disorder leading to bony ankylosis, ossification, and fibrosis of the spine. Airway management is difficult in these patients due to restricted head and neck movement as well as a stiff body posture. This also poses challenges in lying down supine as well as surgical positioning. We report a case of a patient with AS and multiple co-morbidities who underwent a percutaneous nephrolithotomy for renal calculi, and the customisations made in anaesthetic and surgical techniques to safely perform the procedure...

OBJECTIVE: This study aims to evaluate the active and chronic lesions in sacroiliac joints and lumbar spine over a decade of TNFi therapy in patients with AS. METHODS: The study enrolled patients with AS under treatment with a TNFi for over a decade. The patients underwent a new MRI scan of their lumbar spine and sacroiliac joint (SIJ). Two readers evaluated all images. Inflammation of SIJ (SIS), SIJ structural damage (SSS) including Fat Metaplasia, Erosions, Backfill and Ankylosis, and Spondyloarthritis Research Consortium of Canada Bone marrow edema (SPARCC) spine score were recorded...

INTRODUCTION: Temporomandibular Joint (TMJ) reankylosis is one of TMJ arthroplasty complications that can interfere masticatory function and aesthetics. This case report aimed to describe a TMJ reankylosis in growing age patient that occurred 5 years after interpositional arthroplasty using gold foil. Interpositional arthroplasty using temporalis fascia and costochondral graft followed by unilateral coronoidectomy could be a treatment option. CASE PRESENTATION: A 17-year-old female came with inability to open her mouth 5 years after first interpositional arthroplasty using gold foil due to traumatic TMJ ankylosis...
