Subluxation

BACKGROUND: The incidence of developmental dysplasia of the hip (DDH) in Japanese newborns has reduced drastically following a primary prevention campaign initiated around 1972 to 1973; this perinatal education campaign promoted maintaining the hips of newborns in the naturally flexed-leg position. The purpose of the present study was to describe the life course epidemiology of hip osteoarthritis (OA) in adolescent and adult patients and to assess its association with exposure to the primary prevention campaign for DDH...

PURPOSE: Trapeziometacarpal (TM) arthrodesis may increase adduction motion of the thumb metacarpophalangeal (MCP) joint, causing radial collateral ligament laxity. Stability of the MCP joint is important to the long-term functional outcome after TM arthrodesis. This study assessed preoperative and postoperative radial collateral ligament laxity using dynamic radiographs to confirm whether laxity was exacerbated after surgery and examined whether there is a relationship between the fixation angle of arthrodesis and the degree of laxity...

In this paper we synthesize an expansive body of literature examining the multifaceted influence of chiropractic care on processes within and modulators of the neuroendocrine-immune (NEI) system, for the purpose of generating an inductive hypothesis regarding the potential impacts of chiropractic care on integrated physiology. Taking a broad, interdisciplinary, and integrative view of two decades of research-documented outcomes of chiropractic care, inclusive of reports ranging from systematic and meta-analysis and randomized and observational trials to case and cohort studies, this review encapsulates a rigorous analysis of research and suggests the appropriateness of a more integrative perspective on the impact of chiropractic care on systemic physiology...

Background: In the popular fighting sport of boxing, opponents strike each other above the belt line in the face, chest, and belly. The physical parts most exposed are therefore the nose and eyes. In amateur boxing, fights go only three rounds - three minutes for men and one minute for women - with a one-minute break in between. They wear gloves, but the head protection used in the men's game has been removed by AIBA due to the high likelihood of concussion when using head protection. Because chronic ocular changes may take longer than the expected short-term effects, this study included at least 3 years of competitive sports participation...

BACKGROUND: The use of isolated soft tissue repair versus bone block stabilization for the treatment of recurrent anterior shoulder instability in adolescents has no scientific evidence. PURPOSE: To compare the clinical outcomes of adolescent patients who underwent isolated arthroscopic Bankart (iB) repair with those who underwent the arthroscopic Bristow-Latarjet procedure in addition to Bankart (BLB) repair. STUDY DESIGN: Cohort study; Level of evidence, 3...

BACKGROUND: Children with Generalized Joint Hypermobility (GJH) may have a motor developmental delay in the early period and subluxation, fatigue, autonomic dysfunction, and pain arising from ligaments and other soft tissues in advanced ages. Additionally, there is a loss of proprioceptive sensation in children and adults with GJH. AIMS: This study aimed to evaluate sensory processing skills in toddlers with GJH. STUDY DESIGN: A cross-sectional study...

BACKGROUND: Reconstructing bone defects in the upper extremities and restoring their functions poses a significant challenge. In this study, we describe a novel workflow for designing and manufacturing customized bone cement molds using 3D printing technology to reconstruct upper extremity defects after bone tumor resection. METHODS: Computer tomography data was acquired from the unaffected upper extremities to create a detachable mold, which can be customized to fit the joint precisely by shaping the bone cement accordingly...

Nail-patella syndrome, also known as Fong disease, is an uncommon autosomal dominant disorder characterized by a distinctive set of features, including fingernail abnormalities, hypoplastic patellae, radial head dislocation, and iliac horns. This condition often leads to patellar subluxation or dislocation, resulting in knee instability and pain. While existing literature predominantly focuses on the clinical and radiological aspects of nail-patella syndrome-related knee manifestations, only a limited number of articles delve into a meticulous approach to the condition with a comprehensive strategy for diagnosis...

HYPOTHESIS: The purpose of this study was to compare inter-and intraobserver agreement of a novel intraoperative subluxation classification for patients undergoing ulnar nerve surgery at the elbow. We hypothesize there will be strong inter- and intraobserver agreement of the four-category classification system and reviewers will have substantial confidence while reviewing the classification system. METHODS: Four blinded fellowship-trained orthopedic hand surgeons reviewed 25 videos in total on two separate viewings, 21 days apart...

PURPOSE: The aim of this study was to describe the clinical presentation, histopathologic characteristics, and management of phacolytic glaucoma. PATIENTS AND METHODS: The database at the Florida Lions Ocular Pathology Laboratory was searched for surgical specimens at the Bascom Palmer Eye Institute. Patients with a diagnosis of "phacolytic glaucoma" on cytopathology between the years of 1997 and 2023 were included ( n  = 15). Patient demographics, anatomic site, laterality, clinical features, and ocular examination findings were obtained from available medical records...

(1) Background: In elderly patients with type II odontoid fractures, accompanying severe atlantoaxial instability (AAI) is discussed as a marker possibly warranting more aggressive surgical therapy. This study aimed to characterize adverse events as well as the radiological and functional outcomes of surgical vs. conservative therapy in patients with odontoid fracture and AAI. (2) Methods: Patients aged 65 years and older with type II odontoid fracture and AAI treated were included. AAI was assumed if the mean subluxation across both atlantoaxial facet joints in the sagittal plane was greater than 50%...

PURPOSE: To evaluate the surgical outcomes of intrascleral intraocular lens (IOL) fixation using ab interno trabeculotomy (LOT) in patients with exfoliation glaucoma with lens subluxation. STUDY DESIGN: Retrospective case series. METHODS: Twenty eyes of 18 patients with exfoliation glaucoma and lens or IOL subluxations were included. Three success criteria were based on postoperative intraocular pressure (IOP) (A, ≤15 mmHg; B, ≤18 mmHg; C, ≤21 mmHg)...

This case report introduces a novel type of shoulder prosthesis in 2 patients with hemiplegic shoulder subluxation. A unique reel traction device was incorporated to allow easy traction and accurate correction of joint subluxation. X-ray images taken before and after application showed immediate correction effects that were maintained up to 2 hours after application with no change of sling position. These 2 cases support the idea that this new type of shoulder sling could be applied for therapeutic and corrective purposes in hemiplegic stroke patients with shoulder subluxation...

BACKGROUND: The presence of subjective mechanical symptoms, such as clicking or popping, is common in patients presenting for shoulder pain and dysfunction, with unclear clinical significance. The primary objective of this study was to assess whether subjective mechanical symptoms in the affected shoulder were associated with full-thickness rotator cuff tearing in a consecutive, prospective cohort of patients undergoing shoulder magnetic resonance imaging (MRI) for suspected rotator cuff pathology...

INTRODUCTION: Barton fractures are distal radius fractures that extend through the dorsal aspect of the articular surface, with associated dislocation of the radiocarpal joint. They are extremely unstable and require open reduction and internal fixation (ORIF). Delayed presentation is often encountered with difficulty in achieving reduction, and more extensive surgery may be needed. Here, we present a case of a 3-week-old neglected volar Barton fracture of the right wrist treated with the conventional method in a rural setting...

A 42-year-old man presented with neck pain after a fall from a tree. Spine computed tomography (CT) illustrated the right C5 superior articular process fracture without displacement. Magnetic resonance imaging (MRI) confirmed the fracture and injury of the posterior ligament complex. Initially he was managed conservatively with a neck brace as there were no signs of instability or vertebral body misalignment. However, three days after discharge, right shoulder weakness and numbness of the right upper arm became prominent...

BACKGROUND: Concomitant injuries to the radiocarpal ligaments may occur during episodes of distal radius fractures, which may not cause acute subluxation or dislocation but can lead to radiocarpal instability and progress over time. This study aimed to analyze the occurrence of ulnar carpal translation (UCT) after open reduction and internal fixation of distal radius fractures and evaluate the associated factors of UCT. METHODS: The retrospective study has been done now and includes patients treated between 2010 and 2020 who had undergone reduction and locking plate fixation of distal radius fractures...

The modified total Sharp score (mTSS) is often used as an evaluation index for joint destruction caused by rheumatoid arthritis. In this study, special findings (ankylosis, subluxation, and dislocation) are detected to estimate the efficacy of mTSS by using deep neural networks (DNNs). The proposed method detects and classifies finger joint regions using an ensemble mechanism. This integrates multiple DNN detection models, specifically single shot multibox detectors, using different training data for each special finding...

BACKGROUND: Patients with moderate to severe hallux valgus (HV) sometimes exhibit second metatarsophalangeal (MTP) joint dislocation. Second MTP joint instability due to plantar plate (PP) injury has been suggested as one of the causes. However, there have been no reports that quantitatively evaluate this instability. This study aimed to evaluate second MTP joint instability in patients with HV without dislocation via ultrasonography and investigate its relationship with the presence of PP injury or foot form...

INTRODUCTION: Extensor tendon subluxation or dislocation resulting from sagittal band rupture can be associated with snapping, catching, locking, pain, and swelling of the finger. Several etiologies were reported in the literature, with frequent mention of a traumatic rupture caused by a direct blow at the level of the metacarpophalangeal joint (MCPJ). The other causes of sagittal band injuries are degenerative disease, congenital infection, and rheumatoid arthritis. To our knowledge, we report the first case of spontaneous idiopathic bilateral sagittal band rupture...
