Series Preface

S ince its inception 1994, the Master Techniques in Orthopaedic Surgery series has become the gold standard for both physicians in training and experienced surgeons. Its exceptional success may be traced to the leadership of the original series editor, Roby Thompson, whose clarity of thought and focused vision sought “to provide direct, detailed access to techniques preferred by orthopaedic surgeons who are recognized by their colleagues as ‘masters’ in their specialty,” as he stated in his series preface. It is personally very rewarding to hear testimonials from both residents and practicing surgeons on the value of these volumes to their training and practice. A key element of the success of the series is its format. Of note, this format was inspired by Dr. Kenneth Johnson, a foot and ankle orthopaedic surgeon from the Mayo Clinic. Ken was a personal friend of mine. This fourth edition of Master Techniques series is, in my opinion, a testament to his vision and individuality. He wanted to prepare a book about the way he did foot and ankle surgery. He was not interested in presenting the world’s experience, but rather, “here’s how I do it.” The effectiveness of this format is reflected by the fact that it is now being replicated by other publishers. Among other strengths, an essential feature of the Master Techniques series is the standardized presentation and illustration of information with tips and pearls shared by experts with years of experience. Abundant color photographs and drawings guide the reader through the procedures step-by-step. The second key to the success of the Master Techniques series rests in the reputation and experience of our volume editors. The editors are truly dedicated and recognized “masters” with a commitment to share their rich experience through these texts. We are proud of the progress made in formulating the fourth edition volumes and are particularly pleased with the expanded context of this series. Since its inception, new volumes have been added in an effort to remain relevant and to cover topics that are exciting and useful to a broad cross section of our profession. While we have expanded the Master Techniques topics and editors with additional titles, we have remained true to the now classic format. The first of the new volumes was Relevant Surgical Exposures , edited with my son, Matthew. Additional volumes include Essential Procedures in Pediatrics, Soft Tissue Reconstruction, Advanced Techniques in Joint Reconstruction, and Essential Procedures in Sports Medicine . The full library consists of useful and relevant titles covering the full spectrum of our profession. I am pleased to be involved as the series editor, as I feel strongly about the value of the series in educating the surgeon in the full array of expert surgical procedures. The true worth of this endeavor will continue to be mea sured by the ever-increasing success and critical acceptance of the series. I remain indebted to Dr. Thompson for his inaugural leadership as well as to the Master Techniques volume editors and numerous contributors who have been true to the series style and vision. The words of William Mayo are especially relevant to characterize the ultimate goal of this endeavor. “The best interest of the patient is the only interest to be considered.” We are confident that the information in the expanded Master Techniques offers the surgeon an opportunity to realize the patient-centric view of our surgical practice.

Preface

I still remember reading the second edition of Master Techniques in Foot and Ankle Surgery as a resident and fellow as I prepared for my cases on the foot and ankle service each day. I found myself ready each morning to carry out surgeries that my attendings scheduled, no matter what the calendar might have held. The vast array of types and techniques of surgery, described by leaders in the field I would later come to know, drew me to my ultimate decision to specialize in this exciting field. When Dr. Morrey and Dr. Kitaoka asked me edit the fourth edition of Master Techniques in Orthopaedic Surgery , I felt honored and motivated to contribute, but knew I would need help. After all, it was their insight and hard work that brought the book to its current level. However, much has changed as the field rapidly evolves. I have leveraged expertise by colleagues from all over the world to capitalize on the latest advances in our field. While cutting edge research and data drives much of our decision-making in surgery, having a trusted col league take you through a case presents the most valuable opportunity to learn and improve patient outcomes that I know. I have chosen the subsection editors carefully for this series given their international reputation, research, and expertise: A. Holly Johnson (forefoot and MIS), Mark Drakos (sports and Achilles), Constantine A. Demetracopoulos (total ankle), Cesar de Cesar Netto (flatfoot), and John Kwon (trauma and neuromuscular disorder) have provided countless hours to create a book that will serve both as a teaching manual and reference for both trainees and experienced surgeons alike. The vast majority of chapters present new material and, in particular, even new techniques not performed at the time the last edition came out over 10 years ago. This holds true for each subsection, but especially for total ankle and minimally invasive approaches. Chapters on deformity reconstruction, bunion, and tendon/ligament reconstruction also reflect the latest advances. I am confident that in another 10 years we will all read a differ ent book as well. I have tried to balance opinions, strategies, and approaches across all techniques. For example, all current total ankle replacement prostheses have their own chapter, each highlighting positive design features along with tips and pearls from the experts that use them regularly. The same holds true for traditional versus more minimally invasive approaches. Because nothing comes easy in foot and ankle surgery, topics run from the simple to most complex. I hope that you learn as much as I have when reading these techniques, written by the masters in our field. I thank the authors for their tireless efforts despite running busy practices, spending time away from their families, and competing with other academic duties such as teaching and research. I encourage our colleagues in foot and ankle surgery to use these to update their knowledge and as a reference for the cases you perform. I am confident that those reading the chapters will likely be the next ones writing them in the coming years.

Haglund Deformity With Flexor Hallucis Longus Tendon Transfer

Kelly K. Hynes

INTRODUCTION Insertional tendinopathy makes up about 30% of all causes of Achilles tendon pain. 1 Haglund defor mity is a prominent posterior superior border of the calcaneus and is considered part of the spectrum of calcific insertional tendinopathy. Patients present with painful swelling in the posterior aspect of the heel and ensuing problems with rubbing and discomfort from the posterior part of the shoe occurs. True Haglund syndrome is caused by a mechanically induced irritation of the Achilles ten don and associated retrocalcaneal bursa. Patients may present at a younger age with calcific inser tional tendinopathy, sometimes bilateral, which should alert the clinician to the possibility of a more generalized inflammatory arthropathy. The terms “tendinopathy” and “tendinosis” are now widely accepted in the literature as histopath ologic studies of débrided tendon have shown a lack of inflammatory response; mucoid degenera tion and collagen disorganization, fatty infiltration, and increased thickness are the more common findings. 2 Conservative treatments include reducing pressure on the affected area with soft heel counters, open back shoes, and heel lifts. Night splints may be used in the setting of an equinus contracture; however, their efficacy has not been shown in the literature. 3 Repetitive weight-bearing activities should be limited and eccentric Achilles stretching with formal physical therapy is encouraged. We do not advocate the use of steroid injections around the Achilles tendon due to concerns regarding rupture. Studies of extracorporeal shockwave therapy have revealed varying results, but some ben efit has been shown when combined with a physical therapy program. 4 The majority, around 80%, of patients can be reassured regarding the success of nonoperative treatments. 5 Surgical treatment of insertional Achilles tendinopathy in the form of Achilles tendon débride ment, tendon detachment, Haglund excision, and tendon reattachment with or without flexor hallu cis longus (FHL) tendon transfer augmentation has been the mainstay of operative treatment of this condition with generally good outcomes. An FHL tendon transfer may also be used in other presen tations of Achilles tendon deficiency such as a delayed presentation of an Achilles tendon rupture. INDICATIONS AND CONTRAINDICATIONS The decision to operate will ultimately depend on the duration of symptoms, the level of discomfort, and the disability that this causes.

PREOPERATIVE PLANNING Lateral radiographs of the heel (Fig. 24.1) are useful in quantifying the degree of calcification within the tendon insertion, which can help to predict the degree of degeneration present, the likelihood of disrupting the Achilles insertion, and, therefore, the need for surgical augmentation and postopera tive protocol implications. In patients with insertional Achilles tendinopathy, 65% to 80% will have an enthesophyte seen on the lateral radiograph while in people without foot pain, 25% to 35% will have an enthesophyte present. 6 Retrocalcaneal bursitis can be seen as a loss of the normal soft tissue shadowing in the space anterior to the Achilles tendon (Kager triangle) and in long-standing cases may lead to erosion of the cortex of the posterosuperior prominence. Various measurements have been described in attempting to quantify the size of the Haglund deformity. In some cases, magnetic resonance imaging (MRI) assessment of the Achilles insertion and Haglund deformity may be helpful in preoperative planning. Assessment of the thickness of the tendon and intrasubstance degeneration has been found to have implications for the success of nonsurgical man agement. One study found that patients who have greater than 8-mm tendon thickness required sur gical treatment 70% to 90% of the time (Fig. 24.2). 7 The specific indications for MRI in insertional Achilles tendinopathy are not well established. In the author’s experience, patients who have a large Haglund deformity radiographically and clinically are not imaged with MRI preoperatively as an open approach with more significant detachment will be required to sufficiently access the entire area of pathology; therefore, no change in surgical management would occur based on MRI findings. In patients with less clinically apparent disease or where the pathology may be in question, an MRI may be helpful both to confirm the diagnosis as well as to assess the extent of the tendinopathy. In a small number of cases with primarily ventral changes of the tendon, endoscopic calcaneoplasty and tendon débridement may be an option for treatment. This option is also more likely to be considered in patients for who a prolonged weight-bearing time and recovery may not be well tolerated. There have been descriptions of some alternative procedures to standard open débridement, detach ment, Haglund excision, and reattachment, which will not be explored in detail here. Consideration should be made based on physical exam if an adjunctive procedure to improve dorsiflexion range of motion, such as a gastrocnemius recession, is indicated.

deformity débridement have been described but thus far have been limited from widespread use for cases when significant tendon detachment may be necessary due to limitations of percutaneous reat tachment and/or FHL transfer. Minimally invasive techniques are rapidly evolving, and there may be accepted such alternatives to the presently described technique in the not too distant future. SURGICAL TECHNIQUE Technique 1: Haglund Excision Through Tendon-Splitting Approach ●● The patient is placed in a prone position, with the foot elevated with a bolster or blankets under the leg (Fig. 24.3A). ●● The approach is through a posterior midline incision (Fig. 24.3B). Care should be taken to avoid injury to the sural nerve, which may be seen lying along the tendon’s lateral border in the subcu taneous tissue. ●● Alternatives to the posterior midline approach have been described, although they are less com monly used. J-Shaped, transverse, medial, and lateral approached have all been reported. ●● A tendon-splitting approach (Fig. 24.4A) is used, and the tendon carefully dissected to expose degenerative tissue, intrasubstance tears, and intrasubstance calcifications (Fig. 24.4B). A primary goal of this procedure is to perform a thorough débridement of the degenerative areas of tendon and calcifications. This tendon-splitting approach provides excellent access to FHL should aug mentation be required. ●● Varying degrees of tendon detachment may be required in order to gain sufficient exposure of the degenerative areas of tendon insertion and Haglund deformity. By some reports, 70% to 80% tendon detachment is usually needed to gain sufficient exposure. 8 Where possible, leaving the most medial and lateral extents of the tendon attachment intact is very helpful to maintain resting tendon tension and is feasible in all but the most severe cases. ●● Abnormal tendon is excised (Fig. 24.5A). While it may be challenging to distinguish normal from abnormal tendon, uniform tissue that has lost the natural tendon striations and is much thicker in texture than normal tendon should be excised. One way of describing the abnormal tendon has been like the texture of “crab meat,” which is meant to describe disorganization of the fibers and FIGURE 24.2 A.

may provide some guidance for the surgeon in débridement. If it is still difficult to determine normal from abnormal tissue, the primary goal of the procedure is to debulk the tendon to a more normal thickness. Inflamed bursa and scarred or fibrosed fat are removed from above the retroc alcaneal space to define the Haglund deformity (Fig. 24.5B). ●● Once all abnormal tissue from the tendon, and retrocalcaneal space are removed, there is a clear view of the Haglund deformity, calcaneal tuberosity, and posterior subtalar joint (Fig. 24.6). ●● The Haglund deformity is resected with an oscillating saw with a typical excised fragment being 2 cm wide × 3 cm tall × 1 cm deep exposing a large insertion footprint for the Achilles tendon repair (Fig. 24.7). ●● At this point, the remaining Achilles tendon insertion is assessed, and it is determined if augmen tation with FHL tendon transfer is required—often if only poor-quality tendon tissue remains or a significant portion of the tendon insertion was débrided, the author typically considers greater than 50% of the tendon having been débrided as an indication to proceed with FHL transfer; how ever, the evidence for exact indications for augmentation is lacking. ●● If no FHL transfer is performed, the tendon is repaired to the insertion with suture anchors. Both single row (two suture anchors) and double row (four suture anchor) techniques have been described. 9 It is at the surgeon’s discretion as to whether a single or double row technique is cho sen. This should be determined taking into consideration the degree of detachment that has been required to be performed. If a robust tendon attachment remains, consideration of less fixation should be given since suture anchors may cause patients pain as well as add unnecessary foreign material burden. If the majority of the tendon or complete detachment is performed, the added fixation of four anchors may be necessary. In the double-row technique, four holes are drilled for suture anchors into the exposed calcaneal footprint (Fig. 24.8A). These holes are spaced ap proximately 15 mm apart. ●● The two proximal suture anchors preloaded with nonabsorbable suture tape are inserted (Fig. 24.8B). The suture from each anchor is then passed through each side of the Achilles tendon approximately 15 mm from the distal tendon insertion (Fig. 24.8C). FIGURE 24.5 A. The Achilles is partially detached from the calcaneal tuberosity to expose further degeneration and bursal thickening. B. The inflamed bursa and fibrosed fat are removed to reveal the posterior-superior calcaneal prominence or Haglund deformity.
