Ankle Ultrasound

Foot and ankle ultrasound is most commonly used to examine the tendons around the ankle in cases of suspected tears or tenosynovitis. Ultrasound however is also useful in assessing joint fluid, the ligaments, fasclitis, metatarsalgia. Impingement syndromes and in dynamic imaging or guided treatment. The Achilles tendon is the most frequently imaged tendon with the peroneal tendons, anterior and posterior tibials, extensor dlgitorum longus, extensor hallucis longus, flexor digltorum longus and flexor hallucis longus also readily accessible to ultrasound imaging.

Category: Trauma Introduction/Purpose: Fractures of the talar neck and body can be fixed with percutaneously placed screws directed from anterior to posterior or posterior to anterior. The latter has been found to be biomechanically and anatomically superior. Percutaneous pin and screw placement poses anatomic risks for posterolateral and posteromedial neurovascular and tendinous structures. The objective of this study was to enumerate the number of trials for proper placement of two parallel screws and to determine the injury rate to neurovascular and tendinous structures. Methods: Eleven fresh frozen cadaver limbs were used. 2.0 mm guide wires from the Stryker (Selzach, Switzerland) 5.0-mm headless cannulated set were percutaneously placed (under fluoroscopic guidance) into the distal posterolateral aspect of the ankle. All surgical procedures were performed by a fellowship-trained foot and ankle surgeon. Malpositioned pins were left intact to allow later assessment of soft tissue injury. The number of guide wires needed to achieve an acceptable positioning of the implant was noted. Acceptable positioning was defined as in line with the talar neck axis in both AP and lateral fluoroscopic views. After a layered dissection from the skin to the tibia, we evaluated neurovascular and tendinous injuries, and measured the shortest distance between the closest guide pin and the soft tissue structures, using a precision digital caliper. Results: The mean number of guide wires needed to achieve acceptable positioning for 2 parallel screws was 2.91 ± 0.70 (range, 2 - 5). The mean distances between the closest guide pin and the soft tissue structures of interest were: Achilles tendon, 0.53 ± 0.94 mm; flexor hallucis longus tendon, 6.62 ± 3.24 mm; peroneal tendons, 7.51 ± 2.92 mm; and posteromedial neurovascular bundle, 11.73 ± 3.48 mm. The sural bundle was injured in all the specimens, with 8/11 (72.7%) in direct contact with the guide pin and 3/11 (17.3%) having been transected. The peroneal tendons were transected in 1/11 (9%) of the specimens. The Achilles tendon was in contact with the guide pin in 6/11 (54.5%) specimens and transected in 2/11 (18.2%) specimens. Conclusion: The placement of posterior to anterior percutaneous screws for talar neck fixation is technically demanding and multiple guide pins are needed. Our cadaveric study showed that important tendinous and neurovascular structures are in close proximity with the guide pins and that the sural bundle was injured in 100% of the cases. We advise performing a formal small posterolateral approach for proper visualization and retraction of structures at risk. Regardless, adequate patient education about the high risk of injury from this procedure is crucial.

Chronic disorders of the Achilles tendon are frequently treated by foot and ankle surgeons. A number of surgical techniques have been described for treating chronic degenerative Achilles tendinosis. This is the largest reported series evaluating a method of transferring the flexor hallucis longus (FHL) tendon and securing it with an Arthrex interference screw into the calcaneus. Sixty-two patients with Achilles tendinosis underwent Achilles debridement and transfer of the FHL tendon for chronic conditions when greater than 50% of the tendon was involved. All 62 patients were followed for an average of 26.97 months. A modified American Orthopaedic Foot and Ankle Society score was evaluated both preoperatively and postoperatively and demonstrated significant improvement. Because of the anatomical relationship of the FHL tendon to the Achilles tendon and the fact that both tendons act in the same phase, transfer of this tendon in chronic Achilles tendinosis or rupture is a reasonable option. The described technique is advantageous in that it is simple to perform and is less time-consuming than other reported methods. The authors have had no revisions to date.

Tendon Ruptures

Category: Sports Introduction/Purpose: Diabetes Mellitus (DM) is an epidemic affecting millions of individuals in the United States. Multiple studies have demonstrated an increase in complications in foot and ankle surgery in patients with DM, including wound healing complications, surgical site infections (SSI), or surgical failure. The goal of this study was to retrospectively review outcomes data from the National Surgical Quality Improvement Program (NSQIP) to determine the impact of DM on operative treatment of achilles tendon ruptures. Methods: Using the NSQIP from 2006-2015, patients were identified using common procedure terminology (CPT) for Achilles tendon ruptures. Diabetic and non-diabetic cohorts were evaluated to compare demographics, comorbidities, perioperative details and 30-day outcomes. Statistical evaluation included a power analysis for the primary outcome measure of wound disruption as well as univariate analysis was performed using chi-squared or Fisher’s exact and Wilcoxon signed-rank tests. Results: A total of 2,014 patients were identified having sustained an Achilles tendon rupture. There were 1,981 patients without DM and 33 patients with DM. There were no significant differences in postoperative complications, including SSI, medical complications, and 30-day outcomes between patients with DM and non-DM patients undergoing surgical repair of acute Achilles tendon ruptures. The power analysis for wound disruption showed a P=0.9 with an alpha of 0.05, sample size of n=2014, and Pearson correlation coefficient of r=0.0721 Conclusion: While DM has been shown to have an increase in complications in various foot and ankle procedures, this study demonstrates that there is no significant difference in postoperative complications and 30-day outcomes between patients with DM and non-DM patients undergoing surgical repair of acute Achilles tendon ruptures using the NSQIP database from 2006-2015. Based on this data, patients with diabetes mellitus can be considered adequate surgical candidates for acute Achilles tendon rupture repair.

Category: Ankle, Arthroscopy, Hindfoot Introduction/Purpose: Background Achilles tendon chronic rupture lead to proximal retraction of the tendon and have a greater tendency to show poorer functional outcomes than acute ruptures. Numerous surgical procedures have been described to treat this pathology. The transfer of the flexor hallucis longus is a well-established treatment option, usually performed as an open procedure. The aim of this paper is to report a case series of six patients with chronic Achilles tendon rupture treated with endoscopic transfer of FHL. Methods: Six patients with Achilles tendon chronic injuries or re-ruptures were treated with endoscopic FHL transfer. There were four man and two women, average of 50 years, with four left and two right tendons involved, and no bilateral cases. All lesions were at zone 2 (between 2-6 cm proximal to insertion). We describe the surgical technique and report our results at an average of a nine-month follow-up. Results: The average follow-up of the series was 9 months (range, 5–12 months). Three patients had an associate procedure at the Achilles tendon to repair the pre-existent gap, using a minimally invasive technique. On average, we expend 56 minutes to perform the surgery, ranging from 45 to 70 minutes. All patients had a major increase in ATRS score values postoperatively, with an average of 17.8 preoperatively and 83,3 postoperatively No major complications or wound healing problems were noted. Tiptoe stance was possible for all patients without limitation. None of the patients noticed functional weakness of the hallux during daily life activity. Conclusion: Endoscopic FLH transfer is a reliable option for patients with higher skin risk and soft tissue complications. Other studies are needed to compare this technique with the open procedure, gold standard by now, to ensure its safety and efficacy.

ABSTRACT Calcaneal tuberosity fractures comprise only 1 to 2% of all calcaneal fractures. Treatment of these injuries has traditionally included open reduction and internal fixation with various means including lag screws, suture anchors and K-wires. We report on a series of cases treated with excision of the tuberosity fragment with repair of the Achilles tendon supplemented by a flexor hallucis longus tendon transfer.

Abstract Background Alkaptonuria is a rare genetic metabolic disorder due to deficiency of homogentisate 1,2-dioxygenase (HGD), an enzyme catalyzing the conversion of homogentisate to 4-maleylacetoacetate in the pathway for the catabolism of phenylalanine and tyrosine. HGD deficiency results in accumulation of homogentisic acid and its pigmented polymer. Ochronosis is a bluish-black discoloration due to the deposition of the polymer in collagenous tissues. Extensive ochronotic involvement of the Achilles tendon in alkaptonuria and its surgical treatment is rarely reported. Case report A 43-year-old man presented to our clinic in March 2019 with sudden onset of left Achilles tendon pain with no history of prior trauma. Surgical exploration revealed a complete disruption of the tendon at its attachment to the calcaneus. Black pigmentation was extensive and reached the calcaneal tuberosity, extending about 7 cm from the insertion. Discussion Achilles reconstruction was performed using flexor hallucis longus tendon transfer. The patient experienced uncomplicated healing with satisfactory functional results. Conclusion Orthopedic surgeons should be aware of the progressive nature of alkaptonuria. Extensive degenerative changes of the ruptured tendon should be suspected so that physicians can plan tendon repair and facilitate prompt surgical intervention.

In this study, we report the case of a patient with a lobulated expansile lesion of 16.6 cm in its largest diameter, who was referred as having a simple “synovial cyst” in the foot that actually was a giant cell tumor of the tendon sheath along the extensor hallucis longus. Conducting a differential diagnosis of a “synovial cyst” in the foot and ankle, performing adequate surgical planning and using imaging tests, such as nuclear magnetic resonance, increases the probability of treatment success. Level of Evidence V; Therapeutic Studies; Expert Opinion.
