Insertional Achilles tendinopathy: A radiographic cross-sectional comparison between symptomatic and asymptomatic heel of 71 patients

PurposeThis retrospective study aimed to investigate whether the standard radiographic indicators for Haglund's syndrome are applicable to insertional Achilles tendinopathy. MethodsPatients who underwent surgery for insertional Achilles tendinopathy in one heel and experienced no pain in the other heel were enrolled in this study. Preoperative calibrated radiographs of the lateral view of the calcaneus were assessed using (1) calcaneal pitch angle, (2) Fowler-Phillip angle, (3) posterior calcaneal angle, (4) Chauveau-Liet angle, (5) X/Y ratio, (6) Haglund’s deformity height, (7) Haglund’s deformity peak angle, (8) calcification length, (9) calcification width, (10) parallel pitch test, and (11) presence of free body. The Wilcoxon signed rank test and McNemar’s test were used for statistical analyses. ResultsSeventy-one patients (52 males; mean age, 57.2; mean body mass index, 27.1) were included. Mean values for each index in the symptomatic and asymptomatic heels were as follows, respectively: (1) 23.5, 23.0 (p = 0.30); (2) 58.9, 57.8 (p < 0.05); (3) 7.6, 9.2 (p < 0.05); (4) 15.8, 13.9 (p < 0.05); (5) 2.8, 2.8 (p = 0.87); (6) 5.4, 5.0 (p < 0.05); (7) 99.6, 99.0 (p = 0.44); (8) 10.5, 7.6 (p < 0.001); and (9) 5.1, 4.4 (p < 0.05). The sensitivity, specificity, and area under curve of significant indicators were as follows, respectively: (2) 0.78, 0.37, 0.55; (3) 0.45, 0.72, 0.58; (4) 0.63, 0.54, 0.57; (6) 0.45, 0.69, 0.59; (8) 0.48, 0.80, 0.66; and (9) 0.63, 0.54, 0.59. The presence of free body also showed a significant difference between both heels (p < 0.05). ConclusionSome radiographic indicators for Haglund's syndrome are applicable to the diagnosis of insertional Achilles tendinopathy. A comparison of the parameters of Haglund’s syndrome with those of insertional Achilles tendinopathy may illuminate the etiology and pathology of insertional Achilles tendinopathy and lead to novel treatments.

Comparison of Lateral and Central Achilles Tendon-Splitting Approaches in the Treatment of Haglund Deformity.

This study aimed to compare the complications and outcomes of lateral and central Achilles tendon-splitting approaches for the treatment of Haglund syndrome. Patients who underwent surgery for Haglund syndrome between June 2012 and June 2022 were included in the study. Patients undergoing lateral approach surgery were included in group 1, whereas patients undergoing central Achilles tendon-splitting approach surgery were included in group 2. Surgical outcomes of the patients were evaluated using the American Orthopaedic Foot & Ankle Society (AOFAS) ankle hindfoot scale, visual analog pain scale (VAS), and Victorian Institute of Sport Assessment-Achilles (VISAA) scores. In addition, preoperative and final follow-up scores were compared. The study included 66 patients: 32 (14 females, 18 males) underwent surgery using the lateral approach in group 1, whereas in group 2, 34 patients (18 females, 16 males) underwent surgery using the central Achilles tendon-splitting approach. There was a significant statistical difference in the AOFAS, VISAA, and VAS scores between preoperative and final follow-up for both group 1 and group 2 (P < .001, P < .001, P < .001, P < .001, respectively). Group 1 had a small (0.76) relative increase in VAS score compared with group 2 (P = .033). There was no significant difference between the complication rates of group 1 and group 2. In our study, we found the lateral approach and central Achilles tendon-splitting approaches to be safe and effective in the surgical treatment of Haglund syndrome without clinically meaningful differences in outcomes or complication rates.

Percutaneous vs Open Zadek Osteotomy for Treatment of Insertional Achilles Tendinopathy and Haglund's Deformity: A Systematic Review.

Percutaneous Zadek osteotomy (ZO) has emerged as a surgical treatment of insertional Achilles tendinopathy (IAT) over the last decade. Existing literature is limited regarding the comparison of this approach with the more established, open ZO technique. This systematic review aims to evaluate and compare the current data on open vs percutaneous ZO approaches to help set evidence-based guidelines. A systematic literature search was performed using the keywords (Zadek osteotomy) OR (Keck and Kelly osteotomy) OR (dorsal closing wedge calcaneal osteotomy) OR (Haglund Deformity) OR (Haglund Syndrome) OR (Insertional Achilles Tendinopathy) and MeSH terms Osteotomy, Calcaneus, Syndrome, Insertional, Achilles tendon, and Tendinopathy. Our search included the following databases: PubMed, Embase, and the Cochrane Library. The PRISMA protocol and the Cochrane Handbook guidelines were followed. All studies included were published from 2009 to 2024 and included the use of open or percutaneous approaches of ZO for the treatment of IAT with at least a 12-month follow-up. The MINORS score criteria were used to evaluate the strength and quality of studies. A total of 17 studies were reviewed, including 611 subjects and 625 ZO procedures. Of these procedures, 81 (11%) subjects had a percutaneous and 544 (89%) subjects had an open ZO. The mean follow-up time was 16.1 months for patients treated with percutaneous ZO and 36.1 months for patients treated with open ZO. Both open and percutaneous studies included in this review showed postoperative improvements in AOFAS, FFI, VISA-A, and VAS scores in patients with IAT. The reported complication rate was 5.8% among patients treated with percutaneous ZO and 10.2% among patients treated with open ZO. Percutaneous ZO is an emerging approach with substantially fewer documented cases compared with the open ZO. Both percutaneous and open ZO appear to be relatively effective treatments for insertional Achilles tendinopathy with Haglund's deformity. The lower complication rates reported for percutaneous ZO is encouraging. Further investigation with more subjects undergoing percutaneous ZO is clearly needed.

The Heel Complex: Anatomy, Imaging, Pathologic Conditions, and Treatment.

The differential diagnosis for heel pain is broad but primarily involves abnormalities of the Achilles tendon, calcaneus, and plantar fascia. Achilles tendon disorders include tendinosis, tendinitis, and partial or complete tears. Tendinosis refers to tendon degeneration, while tendinitis is inflammation after acute overload. Untreated tendinosis can progress to partial or complete tears. Tendon disorders can be accompanied by paratenonitis or inflammation of the loose sheath enclosing the tendon. Initial management involves rehabilitation and image-guided procedures. Operative management is reserved for tendon tears and includes direct repair, tendon transfer, and graft reconstruction. The calcaneus is the most commonly fractured tarsal bone. The majority of fractures are intra-articular; extra-articular fractures, stress or insufficiency fractures, medial process avulsion, and neuropathic avulsion can also occur. Posterosuperior calcaneal exostosis or Haglund deformity, retrocalcaneal bursitis, and insertional Achilles tendinosis form the characteristic triad of Haglund syndrome. It is initially managed with orthotics and physiotherapy. Operative management aims to correct osseous or soft-tissue derangements. The plantar fascia is a strong fibrous tissue that invests the sole of the foot and contributes to midfoot stability. Inflammation or plantar fasciitis is the most common cause of heel pain and can be related to overuse or mechanical causes. Acute rupture is less common but can occur in preexisting plantar fasciitis. Conservative treatment includes footwear modification, calf stretches, and percutaneous procedures. The main operative treatment is plantar fasciotomy. Plantar fibromatosis is a benign fibroblastic proliferation within the fascia that can be locally aggressive and is prone to recurrence. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Platelet rich plasma (PRP) in the surgical treatment of Haglund's syndrome: the use of PRP membranes as an intra-operative local adjuvant.

Aim Haglund's syndrome may be responsible for chronic pain in the ankle and hindfoot. Although numerous therapeutic approaches have been described in the literature, to this date no consensus over a surgical treatment has been established. We report our experience in the treatment of Haglund's syndrome and pre-insertional calcifications of the Achilles tendon using an open surgical approach and platelet rich plasma (PRP) membranes as a local adjuvant. Methods The study retrospectively evaluated patients with Haglund syndrome treated with a direct posterior access, Achilles tendon split, bursectomy, resection of the heel deformity and topical administration of PRP membranes. After surgery, a standardized rehabilitation protocol was performed. The preoperative and postoperative functionalities of the foot and ankle were assessed using the American Orthopaedic Foot & Ankle Society (AOFAS) score. Intraoperative and postoperative complications were recorded. Results Twenty consecutive patients were included. The mean follow-up was 23 months. No patient had major intraoperative or postoperative complications. After the surgery, the mean AOFAS score increased from 44.1 to 92.0, resulting in a statistically significant increase in patient functionality after the treatment (p=0.001). Conclusion Our results suggest that an open surgical approach consisting of a combination of bursectomy, resection of the calcaneal deformity, and topical administration of PRP membranes may be effective for the treatment of Haglund's disease.

Semi-Automatic 3D Assessment of Zadek Osteotomy Effects

Category: Hindfoot; Sports Introduction/Purpose: Zadek's procedure is a surgical option to treat insertional Achilles tendinopathy(IAT). This procedure consists of a closing wedge osteotomy of the calcaneus with biomechanical consequences. Great modifications in the hindfoot alignment can result in poor functional outcomes for athletes. Additionally, some authors stated that Zadek osteotomy is a good choice for patients with IAT associated with cavovarus foot. This study aims to analyze the hindfoot alignment and the parameters related to Haglund's syndrome after Zadek's osteotomy using a virtual surgical simulation by specific software. The authors hypothesize that the Zadek is an effective technique to decompress the Achilles tendon against the Haglund deformity without major modifications in the alignment. Methods: A total of 20 WBCT scans of patients with IAT were included. The WBCT images were run through the Foot &amp; Ankle module of Disior's BonelogicTM software, creating a 3D virtual model. With this 3D model built into this software, 20 virtual Zadeck osteotomies standardized with a 10 mm resection wedge were performed using the virtual osteotomy module of Bonelogic®. The Calcaneal Inclination angle (sagittal view)7; Talocalcaneal angle (sagittal view)8; Talocalcaneal angle (axial view)8; Saltzman angle (45 degrees view)9; Saltzman angle (20 degrees view)9; Hindfoot moment arm angle;10 Hindfoot angle10; Fowler Philips angle11 and the calcaneal length7 were measured before and after the virtual osteotomy. These results were compared and statistically analyzed. Results: A virtual Zadek osteotomy was realized in 20 WBCT from patients with an insertional Achilles tendinopathy. Most of the patients were female, and the mean age was 55 years. There were significant statistical differences in the average of the calcaneal length (79 mm to 73 mm), Fowler Philips angle (57º to 43º), calcaneal pitch ( 24º to 20º ), sagittal talocalcaneal angle (55º to 47º ), and the hindfoot moment arm angle (20 º to 21,8º). The axial talocalcaneal angle, Saltzman view 45 º and 20 º, and Hindfoot moment arm showed subtle modifications. Conclusion: The virtual analysis of Zadek's osteotomy decreased the Fowler Philips angle, shortened the calcaneus, and modified the alignment in the sagittal view. It suggests that Zadek's procedure reduces the bone impingement with Achilles and the Achilles push. The effect of this osteotomy in Hindfoot Alignment was subtle, modifying only the sagittal plane.

Role of Magnetic Resonance Imaging in Evaluating of Non-Traumatic Chronic Ankle Pain in Adult

Background Chronic ankle pain is a common complaint that can interfere with a patient's routine activities. Despite careful and detailed clinical history and physical examination, providing an accurate diagnosis is often difficult because chronic ankle pain has a broad spectrum of potential causes. Therefore, imaging studies play a key role in diagnosis and management. The ability of MRI to demonstrate soft tissue detail and to visualize high anatomical resolution gives it an advantage in characterization of the abnormal findings. (1) Aim of the Study To highlight the role of magnetic resonance imaging in the assessment of the underlying aetiology of chronic non traumatic ankle pain. Patients and Methods cross sectional study was conducted in Ain Shams University hospitals on patients confirmed with nontraumatic chronic ankle pain undergoing ankle MRI study. Results The most common causes of nontraumatic chronic ankle pain were haglund syndrome five cases (14.3%) and osteoarthritic changes five cases (14.3%). Overall MRI imaging was able to pick probable etiology in our study. Conclusion High soft tissue resolution, nonionizing, noninvasive nature, and multiplanar capabilities of magnetic resonance imaging (MRI) make it an investigation of choice for nontraumatic ankle pain. It demonstrates soft tissue structures including muscles, tendons, ligaments, cartilages, nerves, blood vessels as well as bony structures. It is also useful for guiding treatment decisions and determining response to therapy.

12 Cases of Haglund's Syndrome Detected through MRI.

Haglund's syndrome is a common cause of heel pain but often neglected clinically. Haglund's syndrome refers to a series of symptoms caused by impingement among posterosuperior prominence of the calcaneus, bursa and Achilles tendon. It is difficult to distinguish Haglund's syndrome from other causes of heel pain by clinical diagnosis. Imageology is of great value in the diagnosis of Haglund's syndrome. Our study aims to summarize the Magnet resonance (MR) imaging characteristics of Haglund's syndrome and provide some reference to clinical work. We retrospectively analyzed the MR images of 11 patients (6 males; 5 females; 6 right ankles, 4 left ankles, 1 bimalleolar ankles) who have been clinically and radiologically confirmed Haglund's syndrome. Observation contents: morphological changes of calcaneus and talus, abnormal signal of calcaneus, abnormal Achilles tendon, and soft tissue abnormalities around Achilles tendon. Combined with literature reviews, summarize the MR imaging features of Haglund's syndrome. In 12 ankles, all ankles showed posterosuperior prominence of the calcaneus and Achilles tendon degeneration; 7 ankles showed bone marrow edema; 6 Achilles tendons were graded as either type II or type III tendinosis; 5 Achilles tendons showed partial tear; 12 ankles showed retrocalcaneal bursitis, 7 ankles showed retro-Achilles bursitis, 6 ankles showed Kager's fat pad edema. This study found that MR images of Haglund's syndrome showed bone edema of the calcaneus, degeneration and partial tear of the Achilles tendon, the retrocalcaneal and retro-Achilles bursas, and Kager's fat pad edema.

Haglund's Disease with Clinical and Radiological Findings: 3 Case Reports

Objective: Haglund's Deformity is a variation of the posterosuperior region enlargement of the Os Calcaneus (OC) in the form of exostosis. It is associated with Haglund's Disease (HD), which encompasses Achilles tendinitis, retrocalcaneal bursitis, supra calcaneal bursitis, and inflammation of the Kager fat pad. Diagnosis is based on clinical findings and radiological methods, such as lateral ankle radiographs, Computed Tomography (CT), and Magnetic Resonance Imaging (MRI). This study aims to present three cases of ankle pain diagnosed with HD using radiological imaging. The mean age of our cases was 44.6 years, with two females and one male. Patients commonly present with complaints of pain and swelling behind the heel. Results: Physical examination revealed pain and tenderness upon palpation over the left OC and Achilles tendon insertion. Radiological examination showed osseous protrusion in the posterosuperior part of the OC, indicating Haglund's Deformity. Edema was observed at the bony prominence of the posterosuperior OC, Kager fat pad, and heel area. The treatment plan for all three patients included leg rest splint, anti-inflammatory medication, and physical therapy. Conclusion: In cases of heel pain where traumatic events such as acute fractures are ruled out, MRI should be performed, and Haglund's Syndrome should be investigated if osseous protrusion in the posterosuperior calcaneus is observed on radiographs, along with other findings suggestive of HS.

Double row reconstruction of achilles tendon (speedbridge technique) for haglund syndrome results in early weight bearing

BackgroundReconstruction of tendoachilles (TA) tendon using double row reconstruction (speedbridge technique) following excision of haglund deformity is relatively newer technique. The purpose was to assess the clinical outcome and effects of early postoperative mobilization with speedbridge technique. MethodsThis was a prospective observational study performed between January 2018 to February 2019. All the patients underwent open excision of haglund deformity after complete detachment of TA tendon. Reconstruction of TA tendon was done using fibretape and 4.75 mm biocomposite Swivelock [ArthrexAchilles SpeedBridge Convenience Pack (AR-8928 BC-CP)].Clinical evaluation was done using American Orthopedic Foot and Ankle Society (AOFAS) Hind Foot Score (HFS) and Visual Analogue Scale (VAS). Patients were followed at 6weeks, 6 months,12 months,18 months and 2 years. Results11 female and 2 male patients (16 feet) with mean age of 53.00 ± 4.93 years were analyzed. Full weight bearing mobilization was started on an average of 10 days postoperatively.The mean postoperative HFS, at 24 months of postoperative period, was 87.61 ± 4.69 compared to mean preoperative HFS of 53.07 ± 5.93. ConclusionHaglund deformity excision and reconstruction of Tendoachilles using double row technique is an agile construct for early mobilization with an excellent clinical outcome.

Endoscopic calcaneoplasty with gastrocnemius recession for Haglund's syndrome: Is it safe and effective? Results from a retrospective case series

BackgroundEndoscopic calcaneoplasty (ECP) and gastrocnemius recession (GR) are procedures that have been described to effectively treat Haglund’s deformity and insertional Achilles tendinopathy respectively. The purpose of our manuscript is to evaluate the efficacy and safety of ECP and GR with immediate weightbearing for the treatment of Haglund’s deformity with mild to moderate insertional Achilles tendinopathy. MethodsWe performed ECP coupled with GR on 14 patients with an average age of 52 years. All patients demonstrated < 50% tendinous degeneration on MRI. All were allowed weightbearing as tolerated in a CAM boot within the first post-operative week. AOFAS scores and plain film radiographic findings were collected pre-operatively and post-operatively. ResultsThe radiographic exam of the Fowler-Philip angle significantly improved from an average 60.1–40.7° (p < 0.001). The AOFAS ankle/hindfoot score significantly improved from an average 54.7–91.4 (p < 0.001). The average return to work was 7.5 weeks. There were two cases of temporary sural nerve paresthesia, and two cases of delayed wound healing. ConclusionsThis is the first mid-term study evaluating the outcomes of ECP with GR. The results of our study suggest that ECP with GR followed by immediate weightbearing is a safe and effective procedure for the treatment of Haglund’s deformity and mild to moderate insertional Achilles tendinopathy.

Haglund's Syndrome

Background: Haglund's syndrome an important cause of posterior heel pain presents with a prominent bony contour, a retrocalcaneal bursitis or achillis tendinitis these can also occur in isolation hence for the diagnosis of etiology of Haglund's disease certain radiological parameters and soft tissue parameters have been created to evaluate the anatomical variations which will assist in its exact diagnosis. Study aims to distinguish between the bony and soft tissue causes of Haglund's disease radiologically. Methodology: After Institutional ethical committee clearance an observational cross-sectional study was conducted with subjects coming to radiology OPD for X-ray foot with complains of posterior heel pain fulfilling inclusion and exclusion criteria were examined for X-ray lateral view of foot. Parameters like calcaneal inclination angle (CIA), Fowler Philip angle (FPA), parallel pitch line (PPL), Steffenson &amp; Evenson angle (SEA) measured, posterior/calcaneal spur and posterior calcaneal step were noted. The data obtained was analyzed for mean, Standard deviation, sensitivity % and false negative %. Result: Sensitivity of the parameters were analyzed to find CIA, SEA &amp;PPL to be 63.3%, 55% and 55% sensitive respectively. CIA could be assigned most sensitive but regarding soft tissue parameters none were sensitive. Conclusion: CIA, SEA &amp; PPL were found to be sensitive among bony parameters. But none of the soft tissue parameters were sensitive radiologically highlighting a need for its correlation with clinical symptom in peripheral health centers where MRI is not available. Sensitivity of bony and soft tissue parameters were analyzed to find CIA, SEA &amp; PPL to be sensitive. CIA could be assigned most sensitive among bony parameter but with regards to soft tissue parameters none were sensitive.

The advantage of endoscopic treatment of Haglund's syndrome with the three-portal technique

Introduction/Objective Heel deformity accompanied by pain at the attachment of the Achilles tendon is generally known as Haglund?s syndrome. The prominence of the posterosuperior part of the heel bone generates pressure on the retrocalcaneal bursa and Achilles tendon, causing swelling and pain. The condition itself can be treated using surgical or non-surgical methods. The aim was to present our first experiences in the endoscopic treatment of Haglund?s syndrome, employing the three-portal technique. Methods This study includes ten patients whose surgeries were performed during the period between January 2019, and May 2020. All interventions were endoscopic with the three-portal technique used. The diagnosis was made based on the anamnesis, clinical examination, X-rays, and magnetic resonance imaging diagnostics. For the evaluation of results, the AOFAS (American Orthopedic Foot and Ankle Society) score was used. Results The endoscopic findings in all patients revealed a hypertrophic retrocalcaneal bursa and prominence at the posterosuperior part of the calcaneus, generating pressure on the Achilles tendon. By employing the three-portal technique, considerably better visualization is obtained, enabling easy removal of the degenerated tissue. The radiographic control image was satisfactory. The result of the AOFAS score showed a significant improvement after the surgery. Conclusion The endoscopic approach and the use of the three-portal technique in resolving Haglund?s syndrome is a secure procedure that produces good results. It enables faster recovery and fewer complications compared to open surgery.

Outcomes in Open and Endoscopic Treatment for Haglund's Syndrome and Insertional Achilles Tendinopathy

Category: Arthroscopy; Ankle; Hindfoot; Sports Introduction/Purpose: Haglund's syndrome is a common cause of posterior heel pain and can be associated with retrocalcaneal bursitis and degenerative Achilles tendinosis. Open approaches for resection of the Haglund's lesion have long been employed in patients that fail to improve with conservative treatment. This often involves partial elevation of the Achilles insertion with reattachment. More recently, endoscopic surgical techniques have evolved, enabling more rapid rehabilitation with less tendon disruption. The decision on the surgical approach is influenced by the degree of insertional Achilles tendinosis with endoscopic techniques preferred in the absence of insertional pathology. The primary objective of this investigation was to report on a large series of patients treated surgically for symptomatic Haglund's lesions. Methods: We reviewed the outcomes of Haglund's syndrome surgical cases at our institution over a five-year period. We included cases with insertional Achilles tendinosis and retrocalcaneal bursitis related to the Haglund's lesion, but excluded revisions and cases involving flexor hallucis longus tendon transfers. We recorded patient demographics, sport and activity level, comorbidities, BMI, duration of symptoms, surgical technique, tourniquet time, rehabilitation protocol, postoperative complications, and duration of postoperative follow-up. We also reviewed relevant preoperative imaging and recorded the presence of Achilles insertional degenerative calcification or an insertional calcaneal enthesophyte on radiographs. We then prospectively administered questionnaires regarding return to sport and patient-reported outcome measures including the SANE, PASS, VISA-A and PROMIS (Physical Function, Pain Interference and Global Health domains). Results: In total, 17 of the 77 (22%) included cases were performed with the endoscopic surgical technique. Six patients underwent bilateral Haglund surgeries during the study period, accounting for 12 of the 77 cases. The open Haglund resection group had a higher rate of concomitant Achilles insertional degenerative calcification on radiographs and MRI (72%). In addition, the open group was older than the endoscopic group (average age 54 vs 45), had a higher rate of comorbidities, higher rate of postoperative complications, and a higher rate of return to the operating room for revision surgery (11% vs 0% for endoscopic). Seventeen patients were elite distance running athletes and were preferentially treated by endoscopic techniques (11/17, 64%). At 24-month follow-up, the majority of patients report return to baseline activity. Conclusion: Patients treated surgically for Haglund's syndrome and insertional Achilles tendinopathy generally have good outcomes. Outcomes are better for endoscopically treated patients compared to open treatment, although these patients tend to be younger, healthier, and have less Achilles tendons disease. Still, some degree of Achilles tendinopathy and limited intrasubstance calcification can be successfully addressed with the endoscopic technique. We are endeavoring to better define indications for, and limitations of, the endoscopic technique for insertional Haglund's disease.

Haglund's Syndrome and Insertional Achilles Tendinopathy

Insertional Achilles tendinopathy (IAT) is a degenerative process at the insertion of the Achilles tendon onto the calcaneus. Many possible reasons for why this condition develops exist, and is likely due to a combination of factors, but an abnormal, bony prominence at the posterior-superior aspect of the calcaneus, known as a Haglund's deformity, may play a role in the development of IAT. This exostosis may cause increased compressive forces and irritation of the tendon at the calcaneal insertion, leading to pain and degenerative changes within the tendon. Non-operative treatments, including activity modification, eccentric exercise training, extracorporeal shock wave therapy, shoe wear modifications and orthotic inserts, and injection therapies, are the first line of treatment, but have shown varying levels of success in treating IAT. Operative treatments may be indicated after 3-6 months of failed non-operative treatment. In the case of IAT with Haglund's deformity, we describe the procedure of removing the exostosis, debriding the tendon, and reattaching the tendon to the calcaneus, with the use of the flexor hallucis longus tendon, when indicated. Return to sport timeline may be dependent upon severity of tendon damage pre-injury, but care should be taken to monitor load and pain management in a return to run progression program.

Achilles tendon detachment after local infiltration of corticosteroids

Complete disinsertion of the Achilles tendon is relatively rare but is an injury of considerable clinical significance. A 50-year-old non-smoking man presented with complete disinsertion of the Achilles tendon due to an indirect low-energy trauma shortly after administration of local corticosteroid injections (LCI) for treatment of deep retrocalcaneal bursitis. Imaging studies showed complete disinsertion of the Achilles tendon as well as severe Haglund syndrome and retrocalcaneal bursitis. The tendon was repaired, and the Haglund deformity and retrocalcaneal bursa were then resected. Although Achilles tendon rupture is a frequent complication after LCI, to date, no cases of disinsertion have been published. Surgeons must be aware of this issue, especially in patients with previous insertional calcific Achilles tendinosis and Haglund syndrome. Level of Evidence V; Therapeutic Studies; Expert Opinion.

Open Versus Endoscopic Osteotomy of Posterosuperior Calcaneal Tuberosity for Haglund Syndrome: A Retrospective Cohort Study.

Background:Although endoscopic calcaneoplasty and retrocalcaneal debridement have been extensively applied to treat Haglund syndrome, evidence of the value of the endoscopic procedure remains to be fully established.Purpose/Hypothesis:The purpose of this study was to compare the postoperative outcomes and the amount of osteotomy between open and endoscopic surgery for the treatment of Haglund syndrome. It was hypothesized that endoscopic calcaneoplasty would lead to higher patient satisfaction and lower complication rates compared with open surgical techniques.Study Design:Cohort study; Level of evidence, 3.Methods:The following postoperative outcomes were compared between the open surgery group (n = 20) and the endoscopic surgery group (n = 27): visual analog scale for pain, American Orthopaedic Foot & Ankle Society ankle-hindfoot scale, Foot Function Index, Tegner score, Ankle Activity Score, and 36-Item Short Form Health Survey; postoperative complications; and duration of surgery. To determine the extent of resection, the authors compared the calcaneal height ratio, calcaneal resection ratio, calcaneal resection angle, pitch line, and Haglund deformity height between groups. The learning curve for endoscopic calcaneoplasty was also calculated.Results:There were no significant differences between the open and endoscopic groups on any outcome score. Two patients in the open group reported temporary paresthesia around the incisional site, indicating sural nerve injuries; no complication was reported in the endoscopy group. None of the parameters for extent of resection were statistically significant between the groups. The duration of surgery was 44.90 ± 10.52 and 65.39 ± 11.12 minutes in the open and endoscopy groups, respectively (P = .001). Regarding the learning curve for endoscopic calcaneoplasty (6 surgeons; 27 follow-up patients; 9 patients lost to follow-up), the duration of surgery reached a steady point of 55.68 ± 4.19 minutes after the fourth operation.Conclusion:The results of this study indicated that the endoscopy procedure was as effective as the open procedure. The endoscopic procedure required significantly more time than the open procedure, and the duration of the endoscopic procedure was shortened only after the fourth operation, suggesting that it requires high technical skills and familiarity with the anatomic relationships.

The Zadek calcaneal osteotomy in Haglund's syndrome of the heel: Clinical results and a radiographic analysis to explain its efficacy

Local debridement or decompression of the posterior heel in Haglund's syndrome yields variable results. This condition is sometimes due to an excessively long calcaneus rather than simply a large posterosuperior bony prominence. Failure to address this abnormality may explain the poor results in some series. We recently published a new measurement (the X/Y ratio) which, combined with the calcaneal pitch angle, assesses the abnormality of the shape of the calcaneus. The Zadek osteotomy strongly modifies that shape. We retrospectively reviewed 50 patients treated by a Zadek osteotomy at a mean 7 years follow-up using the AOFAS ankle-hindfoot score, the VISA-A score and Tegner scale. We measured only the X/Y ratio and the calcaneal inclination angle, as the classically described radiographic measurements in Haglund's syndrome are unreliable. We then assessed the condition of the distal end of the Achilles tendon with an MRI. Our results demonstrate excellent outcomes(40/50, 80%) following Zadek osteotomy and correspond to the change in pre- and post-operative measurements, especially the X/Y ratio. An algorithm using those geometrical measurements of the calcaneus is proposed for decision making in Haglund's syndrome.Level of clinical evidence: Level 3.
