Çetin Işık, Mesut Tahta
PURPOSE: We aimed to present our novel technique in the surgical treatment of Achilles tendon avulsions and compare the clinical results of such technique with the repair method using suture anchors. METHODS: A retrospective study was made of patients with Achilles tendon sleeve avulsion and patients where distal portion of the tear prohibited primary repair, surgically treated between January 2009 and January 2013. Twenty-one patients who met the criteria were examined and called for final examination: 9 patients were treated with the novel technique (group 1) and 12 patients were treated with suture anchor repair (group 2)...

Habitually barefoot (HB) children from the Kalenjin tribe of Kenya are known for their high physical activity levels. To date, there has been no comprehensive assessment of foot structure and function in these highly active and HB children/adolescents and link with overuse injuries. PURPOSE: The aim of this research is to assess foot structure, foot function, injury and physical activity levels in Kenyan children and adolescents who are HB compared with those who were habitually shod (HS)...

OBJECTIVE: To investigate changes in soleus H-reflex tests in patients with Hirayama disease (HD) and to analyse correlations between these changes and forward-shifting of the cervical cord during neck flexion. METHODS: The amplitude of the soleus H-reflex with and without vibration on the Achilles tendon was recorded bilaterally in 81 HD patients and 34 controls to measure both the vibratory inhibition index (VII) and the Hmax/Mmax ratio. The maximum forward-shifting degree of cervical cord during neck flexion was measured using dynamic magnetic resonance imaging in all HD patients...

Tendon injuries are major musculoskeletal disorders. Polydeoxyribonucleotide activates the adenosine receptor subtype A2A, resulting in tissue growth and neogenesis. This experimental study confirms that polydeoxyribonucleotide can improve secretion of various growth factors, promote collagen synthesis, and restore tensile strength of the Achilles tendon in a rat model with Achilles tendon injury. Thirty-six male Sprague-Dawley rats, aged 7 weeks, were divided into two groups, and the Achilles tendon was transected and repaired using the modified Kessler's method...

BACKGROUND: The Achilles tendon, the largest and strongest tendon in the human body, is nevertheless one of the tendons which most commonly undergoes a complete subcutaneous tear. Achilles tendon ruptures are especially common in middle aged men who occasionally participate in sport. Even though Achilles tendon ruptures are frequent, up to 25% of acute injuries are misdiagnosed, and present as chronic injuries. METHODS: This is a review article about diagnosis and management of chronic Achilles tendon ruptures...

The transfer of the flexor hallucis longus tendon or flexor digitorum longus tendon is frequently used for the treatment of posterior tibial tendon insufficiency or chronic Achilles tendinopathy. According to several anatomical studies, harvesting the flexor hallucis longus (FHL) tendon may cause nerve injury. Sixty-eight embalmed feet were dissected and anatomically classified to define the relationship between Henry's knot and the plantar nerves. Two different configurations were identified. In Pattern 1, which was observed in 64 specimens (94...

Solitary ankle fracture or Achilles Tendon (AT) rupture might not be an uncommon injury. However, concomitant ipsilateral ankle fracture with AT rupture is rare. The present report discusses this rare combination. A 30-year-old female had fallen while rock climbing and sustained a closed fracture of the medial malleolus with an ipsilateral complete AT rupture. Most of the reported cases had similar patterns, not only in terms of history, but also in terms of a similar fracture pattern. This rare combination of orthopedic injuries tends to occur when an abrupt excessive force is applied to the forefoot, with subsequent ankle hyperextension or hindfoot inversion...

Christopher E Gross, James A Nunley
Although most astute clinicians can diagnose Achilles tendon ruptures by physical examination alone, more than 20% are not accurately diagnosed in a timely fashion. The definition of a "chronic" Achilles tendon rupture in foot and ankle literature varies widely: from 4 to 10 weeks status after injury. Neglected or chronic Achilles tendon ruptures can be significantly disabling to patients if the muscle-tendon unit is stretched beyond its normal passive limit. There are a variety of treatment options that all have valid uses but have not been proven to be superior to one another...

Chronic Achilles tendon ruptures are debilitating injuries and are often associated with large tendon gaps that can be challenging for the foot and ankle surgeon to treat. Preoperative evaluation should include the patient's functional goals, medical comorbidities, MRI assessment of gastrocsoleus muscle viability, condition of adjacent flexor tendons, and size of the tendon defect. Although several surgical techniques have been described, the surgeon must formulate an individualized treatment plan for the patient...

Achilles tendon rupture is a common lower extremity injury seen in the active population. Although reruptures rates have improved with nonoperative functional management, surgical treatment is still preferred by the authors. Minimally invasive techniques allow optimal Achilles tendon rupture apposition and tensioning, with a reduced risk of soft tissue complications associated with the traditional open repair.

Study Design Cross sectional, laboratory study. Background Asymmetrical knee loading has been reported in individuals post-Achilles tendon rupture during jogging and hopping. Yet, no studies have examined knee loads in individuals post-Achilles tendon rupture during high demand tasks, such as single limb landings. Objectives We sought to determine if individuals post-Achilles tendon rupture demonstrated asymmetrical knee loads and impact forces during drop countermovement jumps (Drop CMJ). Methods Achilles tendon length and single leg heel rise test for endurance were assessed in 34 individuals (31 male) 6...

INTRODUCTION: Achilles tendon rupture affects over 11 000 people yearly in the UK, and the incidence is increasing. Controversy remains with regard to the best rehabilitation strategy for these patients. In operatively treated patients, functional bracing provides better outcomes compared with plaster casts. However, the role of functional bracing in non-operatively managed patients is unclear. This is the protocol for a multicentre randomised trial of plaster cast immobilisation versus functional bracing for patients with a non-operatively managed Achilles tendon rupture...

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...

INTRODUCTION: Rupture of the Achilles' tendon is a common injury occurring particularly in middle-aged men due to sports trauma. Operative treatment is preferred generally due to lower risk of re-rupture. Possible complications of the operation include suture granulomas. Suture granulomas might represent a foreign body reaction, which itself is the end-stage response of the inflammatory wound-healing process to biomaterials. It may occur with both absorbable and non-absorbable suture materials such as silk in our case...

The most favorable treatment for acute Achilles tendon ruptures remains controversial. In particular, three key questions are intensively debated: is operative or non-operative treatment superior? If surgery is performed, should open or minimally invasive percutaneous techniques be used? How should the follow-up treatment be carried out? The aim of this article is to answer these essential questions based on the currently available evidence. Non-operative treatment leads to a higher rate of re-ruptures and inferior functional results when compared to operative treatment...

Tendon function and homeostasis rely on external loading. This study investigates the biological mechanisms behind tendon biomechanical function and how the mechanical performance is affected by reduced daily loading. The Achilles tendons of 16 weeks old female Sprague Dawley rats (n = 40) were unloaded for 5 weeks by inducing muscle paralysis with botulinum toxin injections in the right gastrocnemius and soleus muscles. The contralateral side was used as control. After harvest, the tendons underwent biomechanical testing to assess viscoelasticity (n = 30 rats) and small angle X-ray scattering to determine the structural properties of the collagen fibrils (n = 10 rats)...
