medial elbow

BACKGROUND: Autograft palmaris has been the primary choice for the reconstruction of the medial ulnar collateral ligament (UCL) in the elbow. Agenesis of the palmaris tendon is not rare, and outcomes of allograft reconstruction in the breadth of athlete types found in the adolescent population are lacking. HYPOTHESIS: Allograft tendon reconstruction of the medial UCL in the young elbow would have low failure rates and satisfactory outcome scores. STUDY DESIGN: Case series; Level of evidence, 4...

OBJECTIVE:  The aim of this study was to determine if variations in Hounsfield units (HU) are present within the elbow between asymptomatic dogs of two breeds of dogs susceptible to elbow dysplasia. STUDY DESIGN:  Guide Dogs and Border Collies that presented for routine computed tomography (CT) screening for elbow dysplasia prior to breeding were evaluated. All dogs had no documented history of lameness. Dogs diagnosed with CT as being free of elbow dysplasia were included...

Snapping triceps syndrome is a rare cause of medial elbow pain and ulnar neuritis caused by subluxation and triggering of the medial tricipital muscle belly over the medial distal humeral ridge and condyle. The diagnosis and surgical management of snapping triceps syndrome can be challenging due to the subtlety of the symptoms and the infrequent presentation. Despite the diagnosis relying largely on clinical examination, noninvasive dynamic ultrasonography may facilitate detection. Correct recognition of this condition is crucial in the avoidance of surgical misadventure and revision surgery...

BACKGROUND: The region where the ulnar nerve (UN) is swollen in baseball players with ulnar neuropathy is not apparent. This study investigated the UN's cross-sectional area (CSA) at each entrapment point in baseball players. We also aimed to clarify the relationship between valgus instability and the CSA of the UN. METHODS: Forty baseball players were separated into healthy and ulnar neuropathy groups. The CSA and valgus instability were measured using ultrasonography (US)...

CASE: Neglected elbow dislocation and radial neck malunion frequently result in chronic pain, instability, and early arthrosis. These complications are best prevented by early treatment with open reduction, corrective osteotomy, and ligament reconstruction, followed by early supervised physiotherapy. We present a peculiar case with neglected complex elbow dislocation and radial head malunion. In this case, we performed an open reduction of the elbow joint and radial neck corrective osteotomy, medial collateral ligament, annular ligament reconstruction, and lateral collateral ligament repair...

INTRODUCTION: Bibliometric analyses provide an aggregate of the most frequently cited literature in a given field. The purpose of this study was to analyze the top 100 most-cited classical and contemporary papers relating to elbow surgery to serve as a reference for surgeons and trainees for educational and research purposes. METHODS: A search was conducted for all papers containing the term "elbow" in the categories Orthopedics, Surgery, and Sports Science in the Clarivate Web of Science...

BACKGROUND: Injuries to the medial ulnar collateral ligament (UCL) are common among baseball pitchers due to repetitive stress on the soft tissue stabilizers of the elbow during pitching. Dynamic stress ultrasound (SUS) can be used to evaluate the UCL and ulnohumeral joint to identify anatomic risk factors of those who will require UCL reconstruction (UCLR). PURPOSE: To determine whether any adaptive or morphological changes detectable on SUS can predict injury to the UCL in professional baseball pitchers...

OBJECTIVE: To report a case of unilateral lateral coronoid process fragmentation in a dog treated via lateral elbow arthroscopy portals. ANIMAL: A 9-month old male intact English Bulldog. STUDY DESIGN: Case report. METHODS: The dog presented with a history of intermittent right thoracic limb lameness. Orthopedic examination on presentation was unremarkable. Computed tomography of the right thoracic limb was pursued and revealed a mineralized focus along the lateral margin of the lateral coronoid process as well as sclerosis of the medial coronoid process and subtrochlear region of the ulna...

(1) Background: Anatomically pre-contoured plates usually require only minimal or even no intraoperative contouring. For complex cases, such plates also assist the surgeon as an anatomical template during fracture reduction. In this study, we present our experience of using a 3D printing technology for the treatment of bicondylar humeral fractures in feline cadavers. (2) Methods: Surgeries were performed on 15 pairs of front limbs amputated at the scapula. The limbs were obtained from 15 adult cats without obvious pathology of the skeleton...

OBJECTIVE:  The aim of this study was to assess if the level of osteotomy (50 or 75% the length of the humerus), osteotomy angle (5, 10, or 20 degrees), direction of bone alteration (external rotational or medial opening wedge osteotomies), or orientation of osteotomy (perpendicular to the humeral long axis or perpendicular to the weight-bearing axis of the limb) affect pressure through the medial compartment of the elbow. STUDY DESIGN:  Humeral osteotomies were performed at 50 and 75% the length of the humerus on 12 canine cadaver thoracic limbs and patient-specific three-dimensional (3D) printed plates applied to induce the desired alteration...

INTRODUCTION: Sports activity can cause elbow osteoarthritis, which subsequently induces bone deformity. Osteochondritis dissecans (OCD) of the capitellum develops defects of articular surfaces and can exacerbate bone deformity. This study aimed to investigate whether OCD exacerbates deformities in sports-related elbow osteoarthritis. MATERIALS AND METHODS: Twenty-one patients who underwent bilateral computed tomography preoperatively followed by surgery for sports-related elbow osteoarthritis were included...

OBJECTIVE: To analyze the effectiveness of binocular loupe assisted mini-lateral and medial incisions in lateral position for the release of elbow stiffness. METHODS: The clinical data of 16 patients with elbow stiffness treated with binocular loupe assisted mini-internal and external incisions in lateral position release between January 2021 and December 2022 were retrospectively analyzed. There were 9 males and 7 females, aged from 19 to 57 years, with a median age of 33...

BACKGROUND: The optimal limb position during stress ultrasound (SUS) evaluation of elbow valgus laxity has not been standardized. PURPOSE: To compare 2 elbow positions (at 90° and 30° of flexion) and report which position method better represents the increased valgus laxity characteristics of baseball players. STUDY DESIGN: Controlled laboratory study. METHODS: Eighteen college baseball players with no history of elbow pain or elbow disorders who belonged to a college baseball club between April and November 2021 participated in this study...

BACKGROUND: The Glenoid track concept has enabled the categorization of Hill-Sachs lesions (HSLs) into on-track lesions and off-track lesions. Furthermore, among the on-track lesions, further categorization has been established based on the distance from the medial edge of the Hill-Sachs lesion to the medial edge of the glenoid track, into peripheral-track lesions and central-track lesions. Recent studies on peripheral-track lesions and central-track lesions within the glenoid track have shown inconsistencies in failure rates, which deserves further investigation...

PURPOSE: To determine the clinical and radiologic outcomes after surgical repair of medial bursal-side Fosbury flop rotator cuff tears compared with traditional avulsion of tendinous attachments lesions. METHODS: A retrospective cohort study was performed. All patients who had undergone arthroscopic posterosuperior repair were recruited. Patients with previous shoulder rotator cuff surgery were excluded. Recruited patients were divided into 2 groups: one presenting Fosbury flop tears and the other presenting with standard avulsion lesions...

INTRODUCTION: There is a lack of data on the use of thermography for elbow joint inflammation assessment among patients with rheumatoid arthritis (RA). Hence, we aimed to compare thermography with ultrasonography (a more established imaging modality for joint inflammation assessment) in the assessment of inflammation in the elbows of patients with RA. METHODS: Standardised minimum (Tmin), maximum (Tmax) and average (Tavg) temperatures at each elbow (medial, lateral, posterior and anterior aspects) were summed to obtain the thermographic parameters MIN, MAX and AVG, respectively...

Tamandua mexicana is an anteater species native from Mexico to Peru. This species is of great evolutionary interest because it belongs to one of the oldest clades of placental mammals in the American continent. This study aimed to describe the origin, insertion, and arterial supply of the intrinsic shoulder and brachial muscles of T. mexicana. We also compared the masses of the functional groups. Gross dissections were performed on both thoracic limbs of 13 cadavers. ANOVA followed by Tukey's test was used for statistical analyses...

INTRODUCTION/AIMS: Ulnar nerve instability (UNI) in the retroepicondylar groove is described as nerve subluxation or dislocation. In this study, considering that instability may cause chronic ulnar nerve damage by increasing the friction risk, we aimed to examine the effects of UNI on nerve morphology ultrasonographically. METHODS: Asymptomatic patients with clinical suspicion of UNI were referred for further clinical and ultrasonographic examination. Based on ulnar nerve mobility on ultrasound, the patients were first divided into two groups: stable and unstable...

BACKGROUND: The flexor pronator slide is an effective treatment option for ischemic contracture and contracture related to spastic cerebral palsy, but little is known about the use of the flexor pronator slide in other non-ischemic contractures. I propose a flexor pronator slide to simultaneously correct wrist and finger flexor contractures and preserve the muscle resting length. To avoid overcorrection of the deformity, I propose the use of a wide-awake local anesthesia with no tourniquet (WALANT) procedure, in which the patient is able to continually assist the surgeon in assessing the contracture release and improvement in finger movement...

INTRODUCTION AND IMPORTANCE: Several authors have also made reference to a less prevalent condition known in elbow as ulnar nerve subluxation. However, this particular condition tends to manifest primarily in young individuals who engage in professional sports or activities involving extensive use of the forearm. A more severe form of ulnar nerve subluxation, which is ulnar nerve dislocation, gives rise to a characteristic dislocation and relocation of the nerve at the elbow during flexion and extension of the forearm...
