BACKGROUND: A variety of techniques currently exist for ulnar collateral ligament (UCL) reconstruction in symptomatic overhead athletes, all with the potential complication of fracture about the humeral or ulnar tunnels. Far cortical button fixation is a reproducible, biomechanically attractive option; however, no clinical series has been published on this technique to date. This study reports the clinical outcomes, with minimum 2-year follow-up, of a dual far cortical button suspension technique for UCL reconstruction in athletes...

BACKGROUND: Anatomic surgical reduction of intra-articular fractures of the distal humerus is important to achieve the best long-term outcomes and prevent post-traumatic arthritis. In this study we compared the radiographic reduction using the trochleocapitellar index. We also correlated the trochleocapitellar index to the functional outcomes next to the comparison of the triceps brachii lifting approach and olecranon osteotomy approach, 2 common approaches for distal humeral fractures...

Chordomas are rare, slow-growing, locally aggressive bone tumors arising from embryonic remnants of the notochord. Distant metastases most commonly involve the lung, liver, axial skeleton, skin, and lymph nodes. Humeral metastases are extremely rare. We report the case of a recurrent chordoma with humeral metastasis, complicated with pathologic fracture. Fluorine-18 fluorodeoxyglucose positron emission tomography-computed tomography revealed multiple hypermetabolic skeletal lesions, corresponding to the symptoms...

The search for and use of alternative biomarkers of the hyperactive bladder has garnered increasing attention in recent years because they may be considered pathogenetically significant and used as surrogate biomarkers. Promising agents that have met these criteria include proteins cytokines, neurotrophins, tumor necrosis factor (TNF), nerve growth factor (NGF), fibrinopeptides A and B, C-reactive protein, membrane-bound ATPase. Analysis of current scientific literature has demonstrated that specialists in many fields of medicine show interest in endogenous proteins that do not belong to neurotransmitters but affect the contractile ability of myocytes...

Recent studies using geometric morphometrics have shown that estimations of demographic parameters can be made using skeletal elements previously not thought useful for such purposes. This study used geometric morphometrics to assess humeral morphological variation in an adult South African sample, and evaluated the accuracy of sex and ancestry estimations based on this variation. Humeri of 1046 adult South African individuals (464 females, 582 males) were digitized. Data sets were rotated and scaled to a common centroid using Generalized Procrustes Analysis...

Fractures of the scapula are rare and have an incidence of 1% of all fractures. Publications highlight glenoid rim fractures. Classification by Ideberg and Euler and Rüdi are accepted. Euler and Rüdi describe three extra-articular and two intra-articular fracture patterns. The indications for surgery are displaced glenoid fractures, scapula tilt of more than 40° and injuries to the superior shoulder suspensory complex. We describe a case of a 22 year old man, who while cycling collided with a moving car due to wet roads...

Objective: To evaluate the reproducibility and repeatability of Hill-Sachs lesion measurement from computed tomography images, with computer software and tridimensional prototype. Methods: Three-dimensional models were made from computed tomography images from 14 patients with anterior shoulder instability, using InVesalius 3.0® software. Hill-Sachs lesions were measured with Rhinocerus 5.0® software with pre-determined position. Mid-lateral distance, perpendicular to humeral shaft, cranial-caudal distance, parallel to humeral shaft, and the longitudinal distance of the lesion were measured...

Background: Cement augmentation (CA) of humeral head screws in locked plating of proximal humeral fractures (PHF) was found to be biomechanically beneficial. However, clinical outcomes of this treatment have not been well evaluated to date. Objectives: To assess outcomes of locked plating of PHF with additional CA and to compare them with outcomes of conventional locked plating without CA. Methods: 24 patients (mean age, 74.2 ± 10.1 years; 22 female) with displaced PHF were prospectively enrolled and treated with locked plating and additional CA...

Economic pressure highlights the critical need for appropriate diagnosis and treatment of various shoulder pathologies since under-diagnosis and under-treatment can result in increased costs to society in the form of disability and lost production. On the other hand, aggressive over-treatment can further inflate already burgeoning health-care costs and potentially harm the patient. Therefore, it is crucial to distinguish the indications between operative and nonoperative management, especially in common shoulder pathologies such as rotator cuff tears, anterior shoulder instability, biceps tendinitis, lesions to the acromioclavicular joint, and proximal humeral fractures...

BACKGROUND: Lateral malleolus fracture can occur alone or is associated with the fracture of the medial malleolus leading to ankle instability. Treatment is aimed to achieve anatomical reduction and ensure stability. Compared to non-locking plate locking plate provide stable construct and compromise bone vascularity less. However, there is increase wound complication with locking plates than non-locking plates. PHILOS plate combines the principles of fixation with a conventional plate with those of locking screws...

Lesser tuberosity osteotomy (LTO) and subscapularis tenotomy (ST) are used for takedown of the subscapularis during shoulder arthroplasty. LTO offers the theoretical but unproven benefit of improved healing and function of the subscapularis. However, humeral stem subsidence and loosening may be greater when osteotomy is performed, which may compromise functional outcomes. Our hypothesis is that no difference in proximal collar press-fit humeral stem subsidence or loosening exists, with no impairment of functional outcomes using the LTO technique...

Diaphyseal fractures of the distal humerus have a high rate of union when treated with a functional brace or an above-elbow cast (AEC). This study compares alignment of the humerus and motion of the elbow after functional brace or AEC treatment. One-hundred and five consecutive patients with a closed, extra-articular fracture of the distal humeral diaphysis were identified in the orthopedic trauma databases of 3 hospitals between 2003 and 2012. Seventy-five patients with a follow-up of at least 6 months or with radiographic and clinical evidence of fracture union were included (51 treated with functional bracing and 24 treated with an AEC)...

BACKGROUND: Although conventional Bankart repair has been the accepted procedure for traumatic anterior glenohumeral instability, the humeral avulsion of the glenohumeral ligament or an elongation of the capsule remains challenging to decide the appropriate treatment. The anatomical knowledge regarding the whole capsule of glenohumeral joint is necessary to accurately treat for the capsular disorders. The aims of the current study were to investigate the anatomical features of capsular attachment and thickness in a whole capsule of glenohumeral joint...

There are several treatment options for recurrent shoulder instability. The Latarjet addresses bone loss via coracoid transfer, and creates a "sling effect" on the humeral head with the conjoint tendon. It does however carry a high potential risk of complications including graft resorption, hardware failure, and neurologic injury. It is hypothesized that the long head of the biceps can function similarly, without the donor site morbidity of a coracoid transfer. We present a case of recurrent instability and musculocutaneous nerve palsy following primary arthroscopic stabilization three years prior, and treatment via long head of the biceps stabilization...

INTRODUCTION: Posterior circumflex humeral artery (PCHA) aneurysm formation and thrombosis as overuse injury in the dominant shoulder can result in ischemia of the forearm, hand and digits due to arterial embolisms. Increased awareness among physicians is necessary as PCHA pathology (PCHAP) might be underdiagnosed. Knowledge of sports and professions at risk and risk-factors for obtaining PCHAP is essential for the development of future preventive measures. This study aims to identify sports and professions at risk as well as risk factors for PCHAP...
