Surgical Considerations for the Neglected or Chronic Achilles Tendon Rupture: A Combined Technique for Reconstruction

The Achilles tendon is among the most commonly injured tendons in the human body. The most common reason for delayed treatment is a missed diagnosis or a deficiency in presentation. The neglected or chronically ruptured Achilles tendon presents a unique treatment challenge. The surgical approach varies greatly depending on the extent of degeneration and the resultant gap between the opposing tendon ends. Most surgeons have recommended the use of a tendon transfer or augmentation to strengthen the Achilles tendon repair. The following technique uses a flexor hallucis longus tendon transfer with gastrocnemius aponeurosis turndown flap augmentation. This technique has been commonly performed by us with success.     

Surgical Treatment of Neglected Bilateral Hemophilic Equinus Contracture With External Fixation: A Case Report

Hemophilia is a disorder of blood coagulation with X-linked recessive inheritance. It is characterized by uncontrollable hemorrhage, and 80% of these occur intraarticularly. With recurrent hemarthrosis, recurrent synovitis occurs, which eventually leads to the formation of articular contractures. The key to the prevention of hemophilic joint complications is successful prevention of bleeding and management of the initial hemarthrosis. However, after the development of a rigid contracture, surgical correction remains the only method to correct the deformity. Achilles tendon lengthening, synovectomy, anterior osteophyte resection, corrective osteotomies, external fixators, or arthrodesis should be considered as surgical options. In the present report, we describe our experience using hybrid-type external fixators to manage bilateral neglected rigid equinus contractures in a hemophilic patient, with 78 months of follow-up data.     

Comparison of the Complication Incidence in Open Versus Endoscopic Gastrocnemius Recession: A Retrospective Medical Record Review

Gastrocnemius recession is a practical and effective procedure to address gastrocnemius equinus. It has been shown that an equinus deformity can lead to the development of plantar fasciitis, osteoarthritis, and foot ulcerations. The 2 approaches to gastrocnemius recession are open and endoscopic. Both are viable options; however, both also have associated complications. We compared and evaluated the postoperative complications associated with these procedures. The electronic database of our orthopedics division at the University of Florida College of Medicine, Jacksonville, was retrospectively searched to identify all cases of gastrocnemius recession (Current Procedural Terminology [CPT] code 27687), and unlisted arthroscopy (CPT code 29999) from February 2006 to February 2016. The difference in the outcome variable, the incidence of postoperative complications, was assessed using Fisher's exact test. A total of 39 patients (41 procedures) were in the open gastrocnemius recession group and 35 (39 procedures) were in the endoscopic gastrocnemius recession group. The median follow-up time was shorter in the open gastrocnemius recession group than in the endoscopic gastrocnemius recession group (9 versus 12 months; p?<?.001). Postoperative complications developed after 12 of the 80 procedures (15%), with a greater incidence after open than endoscopic procedures (26.8% versus 2.6%; p?=?.003). The complications associated with the open technique included 1 case of scar pain (2.4%), 5 of dehiscence (12.2%), 1 of infection (2.4%), 2 of calf abscess (4.9%), and 2 cases of nerve injury (4.9%). A single complication occurred with the endoscopic technique—1 case of dehiscence (2.6%). To the best of our knowledge, ours is the first study to compare the postoperative complications between these 2 techniques. We found the incidence of postoperative complications was significantly lower in the endoscopic group, emphasizing the benefit of using the endoscopic approach. These findings could prove invaluable when addressing gastrocnemius equinus in those with a greater risk of postoperative complications.     

A Wound Complication After Percutaneous Achilles Tendon Lengthening Requiring Surgical Excision: A Case Report

A percutaneous tendo-Achilles lengthening procedure corrects limited ankle joint equinus by decreasing the pull of the triceps surae complex. The standard technique using 3-incision hemisection described by Hoke is often used in patients with diabetes because of the minimal number of incisions and low risk of wound complications. We describe a patient who underwent percutaneous tendo-Achilles lengthening with a resultant open wound complication requiring staged surgical debridement.     

Gravity Equinus Position to Control the Tendon Length of Reversed Free Tendon Flap Reconstruction for Chronic Achilles Tendon Rupture

Repair of chronic Achilles tendon rupture is a surgical challenge. We describe the use of a free turndown tendon flap augmentation raised from the proximal gastrocnemius aponeurosis. To control optimal tension or the reconstructed Achilles tendon length, we used an original method by referring to the gravity planter flexion ankle angle of the contralateral limb. Key aspects of the technique are described. A retrospective analysis of the short-term outcomes achieved in a case series (n = 56) is presented. The postoperative anthropometric findings are also presented to indicate the successful outcomes achieved with this technique.     

Open Re-rupture of the Achilles Tendon Following Minimally Invasive Repair: A Case Report

In this report, we describe a rare complication of an open re-rupture of the Achilles tendon following a minimally invasive Achilles tendon repair on a healthy 29-year-old active male. The reinjury happened 19 weeks following the primary surgical repair of a spontaneous rupture, performed by minimally invasive technique with the help of a jig using partially absorbable sutures and four locking stitches. The wound of the open re-rupture was transverse, in a perpendicular orientation relative to the longitudinal approach used in the index procedure. Increased scar tissue formation, the absence of an adequate layer of paratenon overlying the primary tendon repair, and foreign-body reaction to the suture may have been involved in the occurrence of this unusual complication in the surgical treatment of Achilles tendon rupture.     

Chronic Achilles Rupture Reconstructed with Achilles Tendon Allograft: A Case Report

Chronic ruptures of the Achilles tendon are more difficult to treat than acute tendon rupture. It has been shown that surgical treatment of chronic Achilles tendon rupture provides better functional results than nonoperative treatment. We present a case of neglected Achilles tendon rupture with a 12-cm defect that was repaired using an Achilles tendon allograft with interferential screws to fix the graft in the calcaneus. The patient recovered his ankle function to normal activities after rehabilitation.     

Triple Achilles Tendon Rupture: Case Report

We present a case report with 1-year follow-up data of a 57-year-old male soccer referee who had sustained an acute triple Achilles tendon rupture injury during a game. His triple Achilles tendon rupture consisted of a rupture of the proximal watershed region, a rupture of the main body (mid-watershed area), and an avulsion-type rupture of insertional calcific tendinosis. The patient was treated surgically with primary repair of the tendon, including tenodesis with anchors. Postoperative treatment included non-weightbearing for 4 weeks and protected weightbearing until 10 weeks postoperative, followed by formal physical therapy, which incorporated an “antigravity” treadmill. The patient was able to return to full activity after 26 weeks, including running and refereeing, without limitations.     

Reconstruction of a Neglected Achilles Tendon Rupture With an Achilles Tendon Allograft: A Case Report

Multiple surgical techniques for repair of neglected Achilles tendon ruptures have been described in the literature. The authors present a case using a freeze-dried Achilles tendon allograft for repair of a neglected rupture of the Achilles tendon with a defect of 10 cm. At 1-year follow-up, the patient achieved pre-injury functional use of the affected limb.     

Calcaneal Avulsion of an Ochronotic Achilles Tendon: A Case Report

Alkaptonuria is a hereditary disorder of phenylalanine and tyrosine, with an incidence of approximately 1/200,000 to 1/1,000,000. Ochronosis is the accumulation of homogentisic acid and its metabolites in connective tissues such as the tendons, cartilage, and skin. In the present case study, a 50-year-old male presented with a nontraumatic calcaneal avulsion without a previous diagnosis of ochronosis. To the best of our knowledge, little information has been reported of this pathology in the Achilles tendon and the surgical management.     

Clear Cell Sarcoma of the Achilles Tendon: A Case Report

Clear cell sarcoma of the Achilles tendon is an extremely rare condition, with a handful of cases reported in the literature over the past 3 decades. Patients usually present late because of the slow progress of the disease and seemingly benign nature of its presentation. Clinical and radiological findings are not enough to make a diagnosis; hence, a high index of suspicion is required. A firm diagnosis is made only after histopathologic studies. We present a rare case of this tumor in a young female, the management plan, and prognostic outlook, with subsequent review of the literature.     

Results of Achilles Tendon Excision for Purpose of Wound Closure: Case Series

The loss of Achilles tendon results in reduced plantar flexion strength; however, in patients who are not fit for major reconstructive surgery, with soft-tissue defects overlying the tendon, Achilles tendon excision is a useful adjunct procedure for wound closure. We report 3 patients with infections around the Achilles tendons needing debridement procedures who underwent Achilles tendon excision for the purpose of wound closure. Local healing was achieved in all patients; all returned to their premorbid ambulatory status, and 2 could perform heel raise. Our series showed that Achilles tendon excision eases soft-tissue reconstruction around it and that the primary aim of wound closure was met with a reasonable functional outcome. As such, it is a viable option for selected patients with infections around the Achilles tendon who are poor candidates for flaps.     

Comparison of Four Methods for Percutaneous Achilles Tendon Lengthening: A Cadaveric Study

Percutaneous Achilles tendon lengthening can result in Achilles tendon rupture. This complication has been controversially linked to torsion effects in the Achilles tendon. Routine percutaneous triple-hemisection techniques (group A), rotary triple-hemisection (group B), distal double-hemisection (group C), and proximal double-hemisection (group D) were compared in cadaveric specimens to provide insights into the mechanism of uneven incision lengthening and inadvertent Achilles tendon rupture. The degree of Achilles tendon torsion on various planes was measured in 20 lower limb pairs from fresh cadavers. The increase in postoperative maximum ankle joint dorsiflexion degree and the length of the lengthened Achilles tendon were greater in group B (p < .05) and group C (p < .05) compared with the routine percutaneous triple-hemisection technique (group A). The width of the tensile gap of the distal incision was significantly greater in group B (p < .05) and group C (p < .05) compared with that in group A. Rotary triple-hemisection was shown to eliminate the effect of Achilles tendon torsion on percutaneous Achilles tendon lengthening. Because proximal double-hemisection is performed away from the distal Achilles tendon where the fibers rotate sharply, the technique results in more even extension of the incisions and achieves a greater increase in the maximum degree of ankle joint dorsiflexion. Uneven incision lengthening was observed with the routine percutaneous triple-hemisection and distal double-hemisection techniques. Achilles tendon torsion affected the surgical outcomes. Rotary triple-hemisection and proximal double-hemisection techniques resulted in more even extension of the incisions and achieved a greater increase in the degree of maximum ankle joint dorsiflexion.     

Ankle Fracture Associated With Rupture of the Achilles Tendon: Case Report and Review of the Literature

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. Imaging studies are useful both for confirming the injuries and for medicolegal and research purposes. Definitive treatment of the AT rupture is usually surgical in young active patients. Concomitant malleolar fractures can be managed conservatively or surgically, depending on the fracture configuration and degree of displacement. The importance of a thorough clinical examination in assessing the musculoskeletal and neurovascular structures in ankle injuries cannot be overemphasized. Knowledge of these injury patterns is crucial to reducing the incidence of residual morbidity such as ankle and foot weakness and loss of motion.     

Percutaneous minimal invasive Achilles tendon lengthening improves clinical and radiographic outcomes in severe flexible flatfeet with shortened triceps sureae complex in early childhood: A retrospective study

BackgroundSevere flexible flatfeet with triceps surae complex shortening are prognostically unfavorable in early childhood and may compromise normal foot development.MethodsThis retrospective, IRB-approved study included 20 children (38 feet) under 6 years with severe flexible flatfeet and triceps surae complex shortening. Treatment included minimally invasive percutaneous achilles tendon lengthening followed by a 4-week cast fixation and corrective orthotic therapy under talo-navicular reposition for at least 6-months. Preoperative weightbearing x-rays and at the last available follow-up included anteroposterior talus-first metatarsal angle and lateral talus pitch, Meary’s and talocalcaneal angle and were compared to reference values. ROM, surgeon-rated clinical outcomes and complications/re-interventions were evaluated.ResultsAge at surgery was 3.7 years (1.3–5.9 y) and follow-up time was 4.3 years (1.1–8.9 y). No complications occurred. Clinical outcome was good (68 %) to very good (26 %). Ratio of normal angles increased significantly for three angles. Dorsiflexion ROM improved from ?5.0 ± 6.8° at baseline to 15.7 ± 7.6°.ConclusionsWith significant improvements in clinical and radiographic outcomes, minimal-invasive percutaneous Achilles tendon lengthening followed by orthotic therapy seems to be a valuable treatment option for selected preschool-aged patients with severe, flexible flatfeet with significantly shortened triceps surae.Level of EvidenceIV     

Concomitant Rupture of Achilles Tendon and Superior Peroneal Retinaculum: A Case Report

A case of a concomitant rupture of the Achilles tendon and superior peroneal retinaculum is presented. This combination of injuries has only been reported once in the available literature. The intraoperative findings revealed a mid-substance failure of the superficial peroneal retinaculum, which is also a rare finding. It is suggested that mid-substance failure of this structure be included within the existing classification scheme for superficial peroneal retinacular tears. The authors also discuss the probable pathoanatomical features of these combined injuries and a proposed mechanism of injury.     

Retrocalcaneal Enthesophyte Resection With Functional Lengthening of the Achilles Tendon and Buried Knot Technique: A Case Series

Retrocalcaneal exostosis can be debilitating and in severe cases, surgical resection is indicated. Complications can arise from surgical resection of the exostosis and reattachment of the Achilles tendon, including irritation of the suture knot, recurrence of the bony prominence, and dehiscence. The use of a buried knot technique with functional lengthening of the Achilles tendon and gastroc-soleal muscle complex can minimize these complications. Complete detachment of the Achilles tendon allows for aggressive and thorough resection of the exostosis and functional lengthening with reattachment. The buried cruciate knot technique allows for firm reattachment with buried knots to prevent soft tissue irritation. A total of fourteen patients (14 limbs) underwent retrocalcaneal enthesophyte resection with functional Achilles tendon lengthening, (8/14) of which had difficultly wearing shoe gear, (10/14) had edema, and (2/14) had erythema preoperatively. Postoperatively, (11/14) of patients returned to full activities and sports, and (11/14) returned to normal shoe gear. Complications included (1/14) of patients with Achilles tendon avulsion and (3/14) of patients with surgical site dehiscence requiring revisional surgery. Overall, this technique helps prevent short-term complications and long-term recurrence due to the functional lengthening mitigating insertional forces on the Achilles tendon.     

Haglund's Deformity as a Cause of Acute Achilles Tendon Rupture: A Case Report

Achilles tendon rupture is a common problem affecting both high level and casual athletes. Haglund´s deformity is an abnormality of the postero-superior part of the calcaneus, which often leads to retro-calcaneal bursitis as well as thickening and inflammation of the calcaneal tendon, a combination of pathologies known as Haglund's syndrome. We report a rare case of a relapse Achilles tendon rupture in a 39-year-old professional handball player with a pronounced painful Haglund´s deformity treated with tendon debridement and reattachment using the Arthrex Speedbridge® system. This case report illustrates a rarely described operative and post-operative management of this unusual combination of Achilles tendon rupture and Haglund´s deformity.     

Facioscapulohumeral Dystrophy: Case Report and Discussion

Facioscapulohumeral dystrophy (FSHD) is often cited as the third most common form of muscular dystrophy. Therefore, it should be considered in patients with complaints of progressive weakness. We present the case of a man with facial, truncal, and leg weakness that initially sought medical attention for lower back pain. Electrodiagnostic testing revealed findings in the trapezius, serratus anterior, biceps, triceps, pectoralis major, tibialis anterior, and gastrocnemius muscles consistent with a myopathic disorder. Subsequent genetic testing identified a FSHD allele size consistent with a FSHD deletion mutation. Therefore, confirming the diagnosis of FSHD. Unfortunately, no effective treatments currently exist for FSHD. However, supportive measures involving physical therapy and the use of orthotics may aid in improving function and mobility.     

Isolated Dislocation of the Posterior Tibial Tendon in an Amateur Snowboarder: A Case Report

Isolated dislocation of the posterior tibial tendon is an uncommon pathologic entity that typically occurs in the setting of acute trauma. The diagnosis remains challenging and is often delayed second to the rarity of the injury and symptoms similar to that of medial ankle sprains and other routinely diagnosed injuries about the ankle. The factors that predispose this tendon to dislocation include a hypoplastic retromalleolar groove, flexor retinaculum insufficiency, chronic repetitive trauma, and a structural abnormality from a previous medial malleolar fracture, or a combination thereof. Dislocation has also been cited as a complication of multiple local steroid injections and tarsal tunnel release. The mechanism of injury appears to involve forced dorsiflexion and eversion of the ankle when the posterior tibial tendon is contracted. Most cases do not respond well to conservative treatment and will require surgery to restore function and eliminate symptoms. We report a case of posterior tibial tendon dislocation related to a snowboarding injury and offer our technique for surgical correction.
