Tendon adhesions are one of the most concerning complications after surgical repair of flexor tendon injury. Extracellular signal-regulated kinase (ERK) 2 plays crucial roles in fibroblast proliferation and collagen expression which contributes to the formation of tendon adhesions after flexor tendon surgery. Using a chicken model, we have examined the effects of a small interfering RNA (siRNA)...

Exposure to chronic skeletal muscle disuse and unloading that astronauts experience results in deconditioning bone remodeling. Tendons involved the transmission of force from muscles skeleton are also affected. Understanding changes occur muscle, tendon, is an essential step toward limiting or preventing deleterious effects reduction mechanical load. Numerous reviews have reported this on both ...

INTRODUCTION Due to advances in technology, segmental gait analysis of the foot is now possible and can elucidate hindfoot deformity in persons with posterior tibial tendon dysfunction (PTTD). This study evaluated the motion of the hindfoot and ankle power following surgical reconstruction for PTTD utilizing a segmental foot model during gait. MATERIALS AND METHODS Twenty patients who underwe...

BACKGROUND The majority of distal biceps tendon injuries can be repaired in a single procedure. In contrast, complete chronic tears with severe tendon substance deficiency and retraction often require tendon graft augmentation. In cases with extensive partial tears of the distal biceps, a human dermal allograft may be used as an alternative to restore tendon thickness and biomechanical integrit...

BACKGROUND There are still controversies about graft selection for primary anterior cruciate ligament reconstruction, especially with respect to knee stability and functional outcome. HYPOTHESIS Biodegradable interference screw fixation of hamstring tendon grafts provides clinical results similar to those achieved with identical fixation of bone-patellar tendon-bone grafts. STUDY DESIGN Coh...

Background & Aims: The Plantaris muscle is located in the superficial posterior compartment of the leg and is absent in some individuals. The present study was undertaken to evaluate the absence variation of Plantaris muscle and its possible relation with Palmaris longus and fifth superficial flexor digitorum of the hand. Methods: 83 fresh cadavers, referred to legal medicine center, Kerman, Ir...

Distal biceps tendon rupture accounts for only 3% 10% of all biceps tendon injuries. The majority of distal biceps tendon injuries are from complete rupture. It is especially rare to diagnose partial rupture of the distal biceps tendon. Our case profiles a chronic partial tear of the distal biceps tendon in a pediatric patient.

Introduction Rectus femoris is a spindle shaped muscle forming part of the quadriceps muscle group in the anterior compartment of the thigh. Traditionally, it is described as having two heads which arise as a straight tendon from the anterior inferior iliac spine and a reflected tendon from the ilium just above the acetabulum. Recent studies have shown that the anatomy of the muscle is more com...

Compliant tendons act as energy stores, which benefit the energetics and power output of a muscle-tendon unit. However the compliance of tendon and the material properties may vary between individuals and hence alter the energy storing capacity of the tendon. We aimed to determine the in vivo Achilles tendon (AT) stress and strain during one-legged hopping and hence the contribution of elastic ...

Both extrinsic and intrinsic tissues contribute to tendon repair, but the origin and molecular functions of extrinsic tissues in tendon repair are not fully understood. Here we show that tendon sheath cells harbor stem/progenitor cell properties and contribute to tendon repair by activating Hedgehog signaling. We found that Osteocalcin (Bglap) can be used as an adult tendon-sheath-specific mark...
