BACKGROUND: Lateral Epicondylitis (LE), is a condition characterized by the pain and tenderness over the lateral epicondyle of the humerus. LE is commonly seen among people who are involved in sports such as tennis and golf. Any activity that repeatedly overstrains the extensor carpi radialis brevis tendon can lead to LE. The management of lateral epicondylitis generally involves the use of counterforce orthosis. The aim of this review is to summarize the evidence regarding the effectiveness of counterforce orthoses on the clinical outcomes of patients with lateral epicondylitis...

Tendon disorders commonly cause hand and wrist disability and curtail the performance of work-related duties or routine tasks. Imaging is often needed for diagnosis, but it requires knowledge of the complex anatomic structures of the tendons of the hand and wrist as well as familiarity with related disorders. This review article aims to provide medical professionals with guidelines for the sonographic assessment of the tendons of hand and wrist and related disorders. Sonographic features of tendon disorders affecting the hand and wrist are described here, specifically: infectious tenosynovitis; tendon rupture or tearing; stenosing forms of tenosynovitis such as De Quervain disease and trigger finger; intersection syndrome; insertional tendinopathy; several forms of tendinous instability such as extensor carpi ulnaris instability, climber finger, and boxer knuckle; and tendinopathy in inflammatory rheumatic diseases...

Quadriceps tendon rupture after total knee arthroplasty (TKA) is a rare but dire complication. It is associated with adverse outcomes and morbidities. Studies on such complications are scarce in the literature. In this study, we share our experience in the management of four patients who sustained quadriceps tendon rupture in the early postoperative period. Efforts should be focused on prevention. Meticulous surgical techniques during the medial parapatellar approach to preserve the integrity of quadriceps can reduce the risk of rupture...

Nelson Martins, Saad Sultan, Diana Veiga, Manuel Ferreira, Filipa Teixeira, Miguel Coimbra
This work proposes a new approach for the segmentation of the extensor tendon in ultrasound images of the second metacarpophalangeal joint (MCPJ). The MCPJ is known to be frequently involved in early stages of rheumatic diseases like rheumatoid arthritis. The early detection and follow up of these diseases is important to start and adapt the treatments properly and, in that way, preventing irreversible damage of the joints. This work relies on an active contours framework, preceded by a phase symmetry preprocessing and with prior knowledge energies, to automatically identify the extensor tendon...

Though the plasticity of human tendons is well explored in adults, it is still unknown how superimposed mechanical loading by means of athletic training affects the properties of tendons during maturation. Due to the increased responsiveness of muscle to mechanical loading, adolescence is an important phase to investigate the effects of training on the mechanical properties of tendons. Hence, in the present study we compared vastus lateralis (VL) architecture, muscle strength of the knee extensor muscles and patellar tendon mechanical properties of male and female adolescent elite athletes to untrained boys and girls...

INTRODUCTION: Thumb basal joint arthroplasty with removal of the entire trapezium is often followed by proximal subsidence and impingement of the thumb metacarpal to the scaphoid, which is a common cause of post-operative thumb pain. Treatment of this impingement is a challenge among surgeons. We performed suspension arthroplasty combined with intercarpal ligament reconstruction using a strip of the extensor carpi radialis longus (ECRL) tendon on a patient suffering from pain caused by this type of the impingement and obtained a successful outcome...

Traditional pull-out techniques for tendon and ligament repair are still widely used in hand surgery, despite constant refinements and the development of other methods of fixation. We propose a modification of the classic technique which utilizes a K-wire as an external strut instead of the classic button. This fixation system can be usefully applied in the fixation of extensor and flexor tendons and reinsertions. It is particularly applicable in situations where a transarticular K-wire is to be used anyway, in situations of temporary joint immobilization and in other situations...

The aim of the study was to evaluate a novel approach to measuring neck muscle load and activity in vehicle collision conditions. A series of sled tests were performed on 10 healthy volunteers at three severity levels to simulate low-severity frontal impacts. Electrical activity-electromyography (EMG)-and muscle mechanical tension was measured bilaterally on the upper trapezius. A novel mechanical contraction (MC) sensor was used to measure the tension on the muscle surface. The neck extensor loads were estimated based on the inverse dynamics approach...

The superficial radial nerve (SRN) is the terminal pure sensory branch of the radial nerve supplying dorsal aspects of the proximal portion of the lateral three and a half digits including the lateral two-thirds of the dorsum of the hand. It transits from its submuscular position to a subcutaneous position by passing between the brachioradialis and extensor carpi radialis longus tendons around 7 to 9 cm proximal to the radial styloid. We present a case where this nerve instead of its normal forearm course, pierced the brachioradialis tendon to become subcutaneous...
