INTRODUCTION: The use of novel bioengineer treatment techniques such as Autologous Tenocyte Implantation (ATI) have shown promising improvements in both pain ratings and functional outcomes in elbow, gluteal and shoulder tendon pathology. This case will review the injury timeline of ATI intervention in an elite male swimmer with subscapularis tendon pathology and investigate whether ATI has a concomitant healing effect associated with improved functional outcomes. METHODS: A palmaris longus tendon biopsy was performed and cells were expanded by in-vitro culture...

Injury to the lunotriquetral ligament can result in midcarpal instability, with resultant alterations in normal wrist kinematics and subsequent arthrosis. We performed a previously undescribed technique of lunotriquetral ligament reconstruction in two patients utilizing a palmaris longus tendon autograft. Average age at presentation was 24 years old with a mean follow up of 10 months. Average range of motion was 62.5° of flexion and 57.5° of extension. Total arc of motion was 83% of the contralateral uninvolved extremity...

Carpal Tunnel Syndrome (CTS) is the most common surgically treated problem in the hand. Aside from the neuropathy itself, the most common findings are fibrosis of the subsynovial connective tissue (SSCT) and increased intra carpal tunnel pressure. Normally, the SSCT is a multilayer tissue interspersed among the carpal tendons and nerve. As the tendons move, successive SSCT layers are recruited, forming a gliding unit and providing a limit to differential movement. Exceeding this limit, damages the SSCT as has been shown in both cadavers and animal models...

Leo M Rozmaryn
Ligament injuries are among the most common musculoskeletal injuries seen in clinical practice and ligaments are the most frequently injured structures in a joint. Ligaments play an important role in balancing joint mobility and joint stability. Disruption of joint ligaments severely impairs joint function. Over the past 10 years, a new appreciation of a neuroanatomy and neurophysiology of joint ligaments and its biofeedback loops to surrounding muscles and tendons has emerged to explain the relationship between primary and secondary restraints that allow normal joint motion yet prevent pathological motion...

BACKGROUND AND AIM OF THE WORK: Fracture-dislocations of the proximal interphalangeal joint are complex injuries, often difficult to treat. Several treatment options have been described. Among them dynamic external fixation proved to be a safe technique leading to good results in many authors experience. The principles of this treatment are to avoid edema, prevent stiffness and tendon adhesions, promote joint remodelling and facilitate rehabilitation. The Ligamentotaxor® device is a simple and reproducible dynamic external fixation system that has been used in recent years to treat proximal interphalangeal joint fracture-dislocations, with favourable results...

Hand trauma arising from postoperative acute or chronic tendon injuries leads to delayed union and is one of the greatest challenges in clinical practice. The present study hypothesized that an extracellular matrix hydrogel made from tendons can promote tendon healing and improve tissue regeneration. To verify this, 36 Wistar rats were subjected to bilateral full-thickness injury of their Achilles tendons, starting from the heel bone along the center line to remove a segment of 5 mm in length and 0.5 mm in width...

BACKGROUND: Distal triceps tendon ruptures are relatively rare. Few studies have investigated functional outcomes after repair. There is no consensus on fixation methods for this injury. The purpose of this study was to compare the functional outcomes and the reoperation rates after distal triceps tendon repairs using transosseous tunnels and suture anchors. METHODS: A multicenter, retrospective review of all primary triceps repairs done between 2006 and 2015 was performed...

Chronic sagittal band injury with tendon dislocation of the extensor digitorum communis in the hand often requires operative stabilization. Various surgical techniques have been reported to repair and reconstruct the sagittal band. Nonetheless, most of the techniques are technically demanding and require donor graft. In this case report, we report a novel surgical technique to centralize and stabilize the tendon by reattaching the radial sagittal band with anchor sutures. The advantages of this new technique are simple, no donor morbidity and stable repair to restore the normal biomechanics of the tendon...

BACKGROUND: Flexor zone II is defined as the region spanning the proximal aspect of the A1 pulley to the insertion of the flexor digitorum superficialis (FDS) tendon. Descriptions of the FDS insertion are inconsistent in the literature, but zones of injury are frequently determined with reference to superficial landmarks. The purpose of this study was to describe the footprint of the FDS insertion and define its relationship to the proximal interphalangeal (PIP) skin crease. METHODS: The FDS insertion on the index, middle, ring, and small fingers was dissected in 6 matched pairs of fresh-frozen cadaveric hands...

OBJECTIVE: We aim to create a novel MRI methodology that employs sport-specific stress views for imaging finger pulley injuries in the evaluation of post-operative healing effectiveness. The goal is to measure the bone to tendon distance (BTD), which is the current standard for determining pulley injuries. MATERIALS AND METHODS: The athlete was imaged in a crimp-grip stressed position to emulate sport-specific biomechanics. A Gradient Echo technique was modified to maximize the signal to noise ratio and minimize distortion near the bone and tendon, simplifying the determination of the BTD...

The brachial artery is the commonest artery injured in the extremities. Although the patients present late, nevertheless reconstructions is advocated in other to salvage the limb and maintain function of the hand. We retrospectively examined 25 consecutive patients with vascular injuries treated at The Cardiovascular and Thoracic Surgery Unit of a tertiary health centre over a period of 4 years. We assessed the pre-tertiary methods of stopping of bleeding injured brachial arteries, mechanisms of injury, associated injuries, treatment and the outcome following vascular repair in terms of functionality of the forearm and the volume of the radial pulsation...

Background In Germany, Hand Surgery is an additional qualification that can only be obtained by a three-year training after a completed residency in General Surgery, Plastic Surgery or Trauma and Orthopaedic Surgery. Nevertheless, injuries and diseases of the hand are also treated by physicians without this particular qualification. It is questionable whether these treatments more often lead to medical malpractice. Material and Methods 376 charges of medical malpractice in surgical treatments of the hand and forearm that were closed in 2014 and 2015 were collected by the Arbitration Board for Medical Liability Issues of the Medical Association of North Germany...

Isolated dorsoradial capsule injuries of the thumb metacarpophalangeal joint are different from those associated with collateral ligament disruption. Early suspicion of this rare injury is important because, if overlooked, ulnarward subluxation of extensor pollicis longus tendon can develop. Functionally, active thumb extension becomes impaired, and over the long term, a thumb Boutonniere's deformity becomes established. Joint hypermobility/instability may predispose to this injury. The 2 cases presented illustrate this through anatomic differences...
