AbstractThe aim of this study was to report a posttraumatic partial Achilles tendon (AT) rupture associated with lateral luxation of the superficial digital flexor tendon (SDFT) in a Whippet. This article is a brief communication. A Whippet was presented with posttraumatic plantigrade stance and non-load-bearing lameness of the right pelvic limb. The objective findings consisted in partial AT rupture and SDFT lateral luxation. Surgical treatment ensued: tenorrhaphy of the torn tendons and calcaneo-tibial screw insertion for tarsal immobilization, followed by suturing of the SDFT retinaculum. A casting bandage was employed for additional immobilization. Nonetheless, a bandage complication prompted the premature removal of the fixation screw and casting wrap. Complete functional recovery was achieved by the 20th postoperative week. The simultaneous occurrence of SDFT luxation and partial AT tear has not been reported in the literature before. The long-term postoperative functional outcome was highly satisfactory.

BACKGROUND: Missed traumatic Achilles tendon ruptures in children are rarely reported in the literature. Various techniques have been described to reconstruct delayed Achilles tendon ruptures for adults, but the long-term consequences in the growing child are unknown. CLINICAL CASE: The article presents a clinical observation of a 8-year-old girl with missed rupture of the Achilles tendon operated 7 weeks after the trauma by end-to-end Kessler-type sutures augmented with the plantaris tendon. At 2-year follow-up, the patient was completely asymptomatic. DISCUSSION: A review of the literature shows that this is the third neglected pediatric case of post-traumatic Achilles tendon rupture. The first case concerns a 10-year-old boy treated successfully six weeks after the traumat by open surgical repair using the Bunnell sutures technique. The second patient was a 7-year-old girl, she was operated 8 weeks after the trauma with a termino-terminal tenorrhaphy using the Bunnell technique augmented with the plantaris tendon. CONCLUSIONS: Using the plantaris tendon to reinforce the Achilles tendon repair offers satisfactory results with minimal morbidity. Prognosis depends on the extent of tendon defect which determines the long-term functional outcome. Any skin wound that sits on the back of the leg requires a systematic and careful physical examination to check the integrity of the Achilles tendon.

<p>The Achilles tendon is the thickest and the strongest tendon in the human body. Many studies, investigating biomechanical properties of plantar flexors muscle-tendon unit after ATR surgery, reported an incomplete calf muscle contractile functional recovery. However, these studies only investigated the plantar flexors muscle function failing to provide information about the adaptive changes in motor strategy. In fact, the development of adaptive changes in motor strategies, due to both mechanical and neural factors, may result in pathological musculoskeletal conditions over the long term. Understanding physiological calf muscle changes due to long-term immobilization may help prevent Achilles tendon re-rupture cases.</p>

Tendon Ruptures

Background: Nonoperative treatment of complete Achilles tendon ruptures generally involves a long period of cast immobilization and is associated with frequent reruptures. Functional nonoperative treatment of complete Achilles tendon ruptures involves the use of a high-shaft boot with a 3-cm hindfoot elevation, in which physical therapy is begun after 3 weeks of wear. We reviewed our long-term results with this treatment protocol to determine its effectiveness. Methods: The indications for nonoperative treatment, defined by ultrasound, were a distance of 10 mm or less between the tendon ends with the ankle in neutral position and complete apposition of the tendon ends in 20 degrees of plantarflexion. From 1990 to 1996, 168 patients were treated; 125 (74%) were available for followup at a mean of 5.5 (2 to 12.7) years after the injury. Results: Good or excellent results were achieved in 92 (73.5%) with complete rehabilitation and return to sports activity at their pre-injury levels. Satisfactory (9%) and poor results (17.5%) were due to pain in the Achilles tendon region, a lengthened Achilles tendon, markedly reduced strength, or a marked reduction of calf size in 25 patients (76%). Eight patients (6.4%) sustained a rerupture. Conclusions: Functional nonoperative treatment achieved good results in patients who had precise sonographic evaluation and who were compliant. As a result of our study, we modified our protocol: (1) a repeat ultrasound examination is done by an experienced sonographer 2 to 5 days after the first to confirm the indications for nonoperative treatment, (2) the use of the 3-cm hindfoot elevation is extended from 6 to 8 weeks to provide a longer protection of the tendon, and (3) patients then wear shoes with 1-cm hindfoot elevation for another 3 months.

Long Term Follow Up

Background and Objectives: The purpose of this retrospective study was to compare the long-term clinical–functional and ultrasound outcomes of recreational athletes treated with two percutaneous techniques: Ma and Griffith (M&G) and the Tenolig technique (TT). Materials and Methods: recreational athletes, between 18 and 50 years of age, affected by acute Achilles tendon rupture (AATR), treated by M&G or Tenolig techniques were recruited. Clinical–functional outcomes were evaluated using Achilles Tendon Rupture Score (ATRS), AOFAS Ankle–Hindfoot score, VAS (for pain and satisfaction) questionnaires, and ultrasound analysis (focal thickening, hypoechoic areas, presence of calcifications, tendinitis and alteration of normal fibrillar architecture). Results: 90 patients were included: 50 treated by M&G, 40 by TT. In all, 90% of patients resumed sports activities, with pre-injury levels in 56% of cases after M&G and in 60% after TT. In the M&G group, the averages of the questionnaires were ATRS 90.70 points, AOFAS 91.03, VAS satisfaction 7.08, and VAS pain 1.58. In the TT group: ATRS 90.38 points, AOFAS 90.28, VAS satisfaction 7.76, and VAS pain 1.34. The TT group showed a significantly higher satisfaction and return to sport activities within a shorter time. In the M&G group, ultrasound check showed a significantly greater incidence of thickening and an alteration of fibrillar architecture in the treated tendon. Three infections were reported, including one deep after M&G, two superficial in the TT group, and two re-ruptures in the Tenolig group following a further trauma. Conclusions: At long-term follow-up, M&G and TT are both valid techniques for the treatment of AATRs in recreational athletes, achieving comparable clinical–functional results. However, TT seems to have a higher patient satisfaction rate, a faster return to sports and physical activities, and fewer ultrasound signs of tendinitis. Finally, the cost of the device makes this technique more expensive.

Oral Steroid Therapy

Spontaneous Achilles tendon rupture associated with long-term oral steroid use is not uncommon, particularly in older patients who use these drugs daily to treat systemic diseases. Rupture often results in a large defect, which complicates surgical repair. The authors review Achilles tendon rupture associated with systemic and local steroid use and present a case of rupture due to chronic oral steroid use in a patient with Addison’s disease.

Abstract This study aims to biomechanically compare four different treatment methods for repair enhancement in Achilles tendon rupture in rats: collagen, collagen and platelet-rich plasma (PRP), collagen and mesenchymal stromal cells (MSC), and a combination of collagen, platelet-rich plasma and mesenchymal stromal cells (CPM) at one and two week healing periods. This study included ninety Lewis rats weighing approximately 200–300 g. Ten rats were used as donors for MSC and PRP. For the remaining eighty rats, the right leg was completely transected 6 mm proximal to the calcaneus bone, suture repaired, wrapped in CollaTape (CoTa), and then closed. An injection of PRP, MSC, or PRP and MSC was given at the wound site to the applicable groups. After one or two weeks recovery time, the rats were sacrificed and both Achilles tendons were removed. The left tendons were used as virgin tissue controls. It was found that the maximum stress at failure, the total strain energy, the average modulus of elasticity, and the elastic strain energy all increase significantly from one week to two week recovery time. However, there was no statistical difference between treatment groups in any of the mechanical properties.

Aims In this study we examined the effect of electroacupuncture (EA) stimulation on the mechanical strength of the rat Achilles tendon after long-term recovery. Methods Using 20 rats, an Achilles tendon rupture model was created in an invasive manner. The rats were assigned to one of three groups, that received EA treatment (EA group), minimal acupuncture (MA group) or remained untreated (Control group). In the EA group, EA stimulation (5 ms, 50 Hz, 20 µA, 20 min) was applied to the rupture region over a period of 90 days (five times/week). In the MA group, needles were inserted into the same positions as in the EA group but no electrical current was applied. After 90 days the tendon was measured to calculate the cross-sectional area of the rupture region. Then, the mechanical strength of the tendon was measured by tensile testing. Results No significant differences were observed between the three groups in cross-sectional area of the injured tendon. For maximum breaking strength, the EA group showed a significantly higher threshold compared with the Control group (P<0.05) but not the MA group (P=0.24). No significant difference was seen between the MA group and the Control group (P=0.96). Conclusion Given the EA group showed a significant increase in maximum breaking strength, it is likely that EA stimulation increases the mechanical strength of a repaired tendon after long-term recovery, and EA stimulation could be useful for preventing re-rupture.
