Using wearable detectors to distinguish alignment alterations in runners along with Exercise-Related knee discomfort.
In men, anxiety was positively associated with greater depression severity; while reporting more social support was negatively associated with depression.

This is a cross-sectional study and thus, no causal conclusions are possible.

Anxiety and poor social support in both genders and lower educational levels in women were associated with increased severity of depression. Early identification of risk factors and appropriate treatment at a primary care setting may help in reducing the morbidity and mortality associated with depression.

The Simple Shoulder Test (SST) is a widely used patient-reported outcome assessment. The purpose of this study was to develop and validate a Japanese version of the SST (SST-Jp).

A two-stage observational study was conducted to validate the cross-cultural adaptation of the SST. A total of 100 patients with shoulder disorders completed the SST-Jp; the Disability of Arm, Shoulder, and Hand assessment; and the Medical Outcomes Short-Form 36 (SF-36) at an initial visit. Thirty-four of the patients repeated the SST-Jp one week after the first examination. The test-retest reliability was quantified using the interclass correlation coefficient, and Cronbach's alpha (α) was calculated to assess internal consistency. Construct validity was assessed using Spearman's rank correlation coefficient.

The internal consistency of the SST-Jp was very high (α= 0.826). The interclass correlation coefficient of the SST-Jp was also high (0.859). There was a strong, positive correlation between the Disability of Arm, Shoulder, and Hand and the SST-Jp (r= 0.717,
< .001). The SST-Jp was significantly correlated with most of the SF-36 subscales. The correlations of the SST-Jp with physical subscales of the SF-36 were stronger than those with the other subscales.

The SST-Jp was found to be a valid and reliable measurement for shoulder joint pain and function assessment among the Japanese population.

The Oxford Elbow Score (OES) is an English-language questionnaire specifically designed to evaluate surgical elbow outcomes. This scoring system has been translated into other languages. Given the lack of an Italian version of the OES, the present study was designed to establish, culturally adapt, and validate the Italian version.

The OES questionnaire was culturally adapted to Italian patients in accordance with the literature guidelines with a pilot phase including seven patients with elbow problems and seven healthy subjects. The study includes 110 participants from three hospitals, who underwent elbow surgery for acute (70%) or chronic diseases. At least one month after elbow surgery, at the "index visit", the physician completed the Mayo Elbow Performance Index and patients completed the following questionnaires the Italian OES, the shortened version of the Disability of Arm, Shoulder and Hand Questionnaire (
DASH) and the Short-Form 36 Health Survey. Internal consistency was evaluated using Cronbacisits ranged from 33.9 for OES pain, to 44 points for OES function and OES social/psychological. find more The effect size and the standardized response mean were >0.8 for all OES domains.

This study demonstrates that the Italian version of the OES, translated in accordance with the international standardized guidelines, is reliable, valid, and responsive in patients who have undergoneelbow surgery.

To determine interobserver agreement in the classification by X-rays and by computed tomography (CT) scan of the coronal shear fractures of the capitellum and trochlea as well as the agreement between these two tests.

Patients with coronal shear fractures of the capitellum who were managed at our center between January 2008 and December 2017 were included. This retrospective cohort study was carried out with the approval of the ethics committee of our institution (Nº IIBSP-Cod-2019-02, Ref.19/070). Clinical, radiographic, and elbow-specific outcomes, including the Mayo Elbow Performance Index, were evaluated. Three observers analyzed the preoperative X-rays from all the cases. Each one of them independently classified the fractures according to the Bryan and Morrey classification (with the modification of McKee etal). The interobserver agreement was calculated by Cohen kappa coefficient. The same methodology was used to analyze the CT scan. Thereafter, one single value was determined for each X-ray and CTme fractures were analyzed by CT scan. The authors routinely recommend CT scan to assess the extent of the fracture and perform surgical planning.
Our results demostrated that simple X-rays do not allow for the adequate interpretation of distal humeral coronal plane fractures. Although an acceptable interobserver agreement was found, there is no agreement when the same fractures were analyzed by CT scan. The authors routinely recommend CT scan to assess the extent of the fracture and perform surgical planning.
Repetitive mechanical stress on the elbow joint during throwing is a cause of ulnar collateral ligament dysfunction that may increase the compressive force on the humeral capitellum. This study aimed to examine the effects of ulnar collateral ligament material properties on the humeral capitellum under valgus stress using the finite element method.

Computed tomography data of the dominant elbow of five healthy adults were used to create finite element models. The elbows were kept at 90° of flexion with the forearm in the neutral position, and the ulnar collateral ligament was reproduced using truss elements. The proximal humeral shaft was restrained, and valgus torque of 40 N·m was applied to the forearm. The ulnar collateral ligament condition was changed to simulate ulnar collateral ligament dysfunction. Ulnar collateral ligament stiffness values were changed to 72.3 N/mm, 63.3 N/mm, 54.2 N/mm, 45.2 N/mm, and 36.1 N/mm to simulate ulnar collateral ligament laxity. The ulnar collateral ligament toe region the lateral part of the capitellum.
Under elbow valgus stress with elbow flexion of 90° and the forearm in the neutral position, ulnar collateral ligament dysfunction increased equivalent stress on the humeral capitellum during the finite element analysis. The highest equivalent stress was noted on the lateral part of the capitellum.
The purpose of this analysis was to analyze outcomes of distal biceps reconstruction with soft tissue allograft in the setting of chronic, irreparable distal biceps ruptures. The outcomes of these cases were then compared with a matched cohort of distal biceps ruptures that were able to be repaired primarily.

Retrospective review of an institutional elbow surgery database was conducted. All cases of distal biceps repairs were identified by Common Procedural Terminology, ICD-9, and ICD-10 codes from January 2009 to March 2018. A direct review of operative reports was then conducted to identify which cases required allograft reconstruction. After identification of this population, a 21 manually matched cohort of patients who underwent primary repair was generated using age, gender, body mass index, and age-adjusted Charlson Comorbidity Index. Finally, the allograft reconstruction and matched primary repair cohorts were compared for reoperation, range of motion, and patient-reported outcomes scores.

There irect repair in the acute setting is preferred; however, even in the setting of a distal biceps reconstruction with graft augmentation, they can expect low complications and good functional results.
Medial elbow pain is a common complaint in overhead throwing athletes. The throwing motion places repetitive tensile and compressive forces on the elbow resulting in significant stress across the ulnohumeral joint. This stress can result in soft-tissue, ligamentous, and ulnar nerve injury. The purpose of this study was to retrospectively investigate the clinical findings and outcomes, including return to play rates, of patients who underwent ulnar nerve transposition surgery for isolated ulnar neuritis.

Throwing athletes who underwent isolated, primary ulnar nerve transposition surgery over an eight-year period, 2009 to 2017, were identified and included in our analysis. Nonthrowing athletes, those who underwent revision ulnar nerve transposition surgery, and those who underwent concomitant ulnar collateral ligament reconstruction or repair were excluded. Patients were contacted to complete the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score as well as a return to play rate questionnaire. The mini allows athletes to return to throwing with low reoperation rates. However, more than half of the athletes in our analysis sustained a subsequent ipsilateral shoulder or elbow injury. Further investigation regarding outcomes in throwing athletes after ulnar nerve transposition surgery is warranted.

Surgical treatment of displaced olecranon fractures in the elderly has a high rate of complications, including wound breakdown and fixation failure. The purpose of this study was to assess the clinical, radiographic, and functional outcomes of nonsurgical management of displaced olecranon fractures in low-demand elderly and medically unwell patients.

A retrospective review of 28 patients with displaced closed olecranon fractures was performed with an average follow-up of 11 months. The mean age at the time of injury was 79 ± 10 years. The average Charlson Comorbidity Index was 6.4 ± 2.6. Treatment modalities were at the discretion of the treating surgeon. A sling alone was used in 3 cases, an extension circumferential cast in 9, or a plaster or thermoplastic splint in 16. The mean period of immobilization was 5 ± 1 weeks. Outcomes included range of motion, ability to perform active overhead extension, as well as radiographic and functional outcomes.

At final follow-up, the mean elbow range of motion fordy adds to the growing literature that supports nonoperative management of displaced olecranon fractures in elderly and medically unwell patients with low upper extremity demand. Patients can be counseled that they have a good chance of obtaining overhead extension, with minimal pain. Posteriorly based splints should not be used to minimize skin complications.
