Abstract
BACKGROUND Achilles tendon partial tears are not easy to diagnose and to manage. Most frequently, they are located in the midportion and insertional area. These entities result from different pathologic pathways, and different treatment strategies are applied. The outcome is rarely investigated. METHODS This study includes patients who underwent surgery for partial tears in the midportion or retrocalcaneal Achilles tendon area between the years 2009 and 2015 by a single surgeon. Patients were prospectively assessed preoperatively and 3, 6, and 12 months postoperatively, using the VISA-A-G questionnaire. The final retrospective follow-up was performed after a minimum of 3.5 years postoperatively. Forty-eight Achilles tendon partial tears at the level of the retrocalcaneal bursa (impingement lesions) and 27 midportion Achilles tendon partial tears were identified. After applying rigorous exclusion criteria, 21 and 16 cases, respectively, remained for the final follow-up. Results were analysed by inferential and descriptive statistics. RESULTS The VISA-A-G outcome scores improved significantly from preoperative to 6 months, 12 months, and final postoperative assessment. Preoperatively, the average VISA-A-G score was 42.1 (range, 18-73) for patients operated for Achilles tendon partial tears at the level of the retrocalcaneal bursa and 44.6 (range, 10-73) for the midportion Achilles tendon partial tear group, respectively. At final follow-up 88.8 (range, 15 to 100) and 96.9 (range, 71 to 100) were scored in the respective treatment groups. A repeated measures ANOVA determined that mean performance levels showed a statistically significant difference between measurements (p < 0.001). There was no systematic effect found between groups (p = 0.836). CONCLUSIONS In Achilles tendon partial tears recalcitrant to conservative treatment, operative intervention is highly successful in most cases, irrespective of the level of the injury. Results were statistically equal when comparing the midportion and retrocalcaneal Achilles tendon partial tear groups. TRIAL REGISTRATION DRKS, DRKS00014266. Registered 06 April 2018.

Abstract
PURPOSE In this study, we performed a comparison between open calcaneoplasty through transtendinous approach and endoscopic calcaneoplasty for Haglund's disease. METHODS A retrospective review was performed of patients who had undergone either a calcaneoplasty with transtendinous approach or endoscopic for Haglund's disease from three centres. Inclusion criteria were patients with Haglund's disease confirmed radiographically, neutral alignment of the hindfoot and at least one year of follow-up. Patients were excluded in case of ipsilateral ankle osteoarthritis or other neighbouring joints, previous foot surgery, hindfoot malalignment and marked calcific insertional Achilles tendinosis. A chart review was performed to collect demographic data, including age, sex and body mass index (BMI). Functional outcome analysis included the Foot Function Index, AOFAS score and VAS for pain pre-operatively and post-operatively at the last follow-up. This patient-reported outcome scores were used in the native language of each patient (Italian). RESULTS Clinical and functional outcomes were collected from 54 patients (28 heels treated by open technique and 26 heels treated by endoscopic technique). In the open group, the AOFAS score improved from a pre-operative value of 65.67 ± 10.09 points to a value of 91.78 ± 9.67 points at the last follow-up (P < 0.05). In the endoscopic group, the AOFAS score improved from a pre-operative value of 66.69 ± 7.19 points to a value of 93.69 points ± 10.04 at the last follow-up (P < 0.05). The VAS and the FFI (Disability and Pain) scores were also improved significantly in both groups at the final follow-up evaluation (P < 0.001). Comparing the final follow-up post-operative clinical scores between the two groups, there was no difference in the AOFAS, VAS or the FFI scores between the two groups. No major complications were recorded, except for one Achilles tendon tear after open calcaneoplasty. The satisfaction rate was similar for both techniques. CONCLUSIONS Both techniques provided good clinical outcomes with a low rate of complications.

Abstract
Objective To review the current research on the diagnosis and treatment of Haglund syndrome. Methods The domestic and foreign literature about Haglund syndrome in recent years was extensively reviewed to summarize and analyze the etiology, anatomy, clinical manifestations, diagnosis, and treatment of Haglund syndrome. Results The etiology of Haglund syndrome is not very clear, and it may be related to local friction and high gastrocnemius muscle tension, and there may be a certain genetic tendency. The local anatomy is more complex and there are many adjacent tissue structures. Haglund malformation may cause the impingement of the posterior heel bursa and Achilles tendon insertion, lead to wear of the posterior heel bursa and the Achilles tendon insertion, and finally result in pain. The FPA (Fowler-Philipp angle), CPA (calcaneal pith angle), PPL (parallel pitch lines), CLA (Chauveaux-Liet angle), and X/Y ratios (ratio of total calcaneal length to calcaneal tuberosity length) measured on X-ray film can be used for the diagnostic measurement of Haglund malformation. Treatment includes conservative and surgical treatment (open Haglund ostectomy, dorsal closed wedge osteotomy of the calcaneus, and arthroscopic Haglund osteotomy). Conclusion Both open and arthroscopic Haglund ostectomy and dorsal closed wedge osteotomy of the calcaneus can achieve satisfactory results, but minimally invasive treatment is the current development trend. Surgeons should pay attention to the management of the calcification of Achilles tendon insertion and reconstruction of Achilles tendon insertion.

Abstract
Haglund's syndrome is impingement of the retrocalcaneal bursa and Achilles tendon caused by a prominence of the posterosuperior calcaneus. Radiographic measurements are not sensitive or specific for diagnosing Haglund's deformity. Localization of a bone deformity and tendinopathy in the same sagittal section of a magnetic resonance imaging scan can assist with the diagnosis in equivocal cases. The aim of the present cross-sectional study was to determine the prevalence of Haglund's syndrome in patients presenting with Achilles tendinopathy and note any associated findings to determine the criteria for a diagnosis of Haglund's syndrome. We reviewed 40 magnetic resonance imaging scans with Achilles tendinopathy and 19 magnetic resonance imaging scans with Achilles high-grade tears and/or ruptures. Achilles tendinopathy was often in close proximity to the superior aspect of the calcaneal tuberosity, consistent with impingement (67.5%). Patients with Achilles impingement tendinopathy were more often female (p < .04) and were significantly heavier than patients presenting with noninsertional Achilles tendinopathy (p = .014) or Achilles tendon rupture (p = .010). Impingement tendinopathy occurred medially (8 of 20) and centrally (10 of 20) more often than laterally (2 of 20) and was associated with a posterior prominence or hyperconvexity with a loss of calcaneal recess more often than a superior projection (22 of 27 versus 8 of 27; p < .001). Haglund's deformity should be reserved for defining a posterior prominence or hyperconvexity with loss of calcaneal recess because this corresponds with impingement. Achilles impingement tendinopathy might be more appropriate terminology for Haglund's syndrome, because the bone deformity is often subtle. Of the 27 images with Achilles impingement tendinopathy, 10 (37.0%) extended to a location prone to Achilles tendon rupture. Given these findings, insertional and noninsertional Achilles tendinopathy are not mutually exclusive and impingement might be a subtle, unrecognized cause of Achilles tendinopathy and subsequent rupture.

Open versus endoscopic bone resection of the dorsolateral calcaneal edge: a cadaveric analysis comparing three dimensional CT scans. J Foot Ankle Res 2014; 7:56.

Abstract
BACKGROUND It has been claimed that endoscopic calcaneoplasty offers some advantages over open techniques in the surgical treatment of Haglund's deformity due to reduced postoperative complications like stiffness and pain. Bony over-resection places patients at risk of these complications. The resulting question with regard to the quantitative differences of the extent of the bone removed using these two techniques has not yet been answered. The purpose of the study was to determine the resection volume of calcaneal bone for open and endoscopic surgical techniques. METHODS 16 feet obtained from body donors were operated on in equal parts using either open surgical or endoscopic techniques, with the technique selected on a random basis. High-resolution CT scans were obtained before and after the interventional procedure and analysed to obtain 3-D polygon models. Post-operative models were subtracted from pre-operative models to provide the volume change resulting from the intervention. This was then correlated with the bone mineral density (BMD) of the preparation. RESULTS The extent of bony resection was greater in open surgical techniques than in endoscopic approaches. The average volume of bone resection was 0.80 (±0.34) cm(3) in the endoscopic group and 3.04 (±2.91) cm(3) in the group that underwent open surgery. After adjustment for bone mineral density the extent of the resection was significantly larger (p = 0.018) in the group undergoing open surgery. The two groups did not differ significantly with regard to BMD (p > 0.1). The extent of the resection fell by 0.011 cm(3) per 1 mg/cm(3) areal bone mineral density, i.e., a slightly lower degree of bone resection was associated with a higher bone mineral density. CONCLUSIONS Assuming that the resection volume was adequate to treat the patient's complaints a smaller resection volume seen in our study using an endoscopic technique might lead to fewer postoperative complaints and faster recovery.

Abstract
BACKGROUND The results of operative treatment for recalcitrant midportion Achilles tendinopathy and recalcitrant retrocalcaneal bursitis were evaluated using the patient administered, disease specific, and validated VISA-A-G questionnaire. METHODS A cohort of 89 patients was prospectively followed. These patients underwent operations for sport induced midportion Achilles tendinopathy (39 procedures) or retrocalcaneal bursitis (55 procedures). Depending on the individual intraoperative findings the patients of either disease were treated with two respective operative modifications (tendon repair or no tendon repair). Preoperative and follow-up status (3, 6, and 12 months) were investigated using the VISA-A-G questionnaire. RESULTS Preoperatively, the four groups scored from 37.0 ± 17.6 to 45.9 ± 15.2 (p = 0.376-0.993) on the VISA-A-G questionnaire. Six and 12 months postoperatively, the VISA-A-G scores improved significantly (p < 0.001). Twelve months postoperatively, the groups' scores were not different (p = 0.100-0.952) and ranged from 80.8 ± 17.9 to 90.3 ± 10.6. CONCLUSION Retrocalcaneal bursitis and midportion Achilles tendinopathy responded equally well to operative treatment. When repaired, additional tendon lesions did not influence this result. We demand to differentiate not only between midportion Achilles tendinopathy and retrocalcaneal bursitis but also to identify additional Achilles tendon lesions to specifically address these lesions during operative procedures.

Abstract
BACKGROUND We questioned whether different forms of Achilles tendon overuse injuries can be differentiated by retrocalcaneal bursa pressure measurement. METHODS Retrocalcaneal bursa pressure was determined by using invasive pressure measurement in patients suffering from retrocalcaneal bursitis (n=13) or Achilles tendinopathy (n=15), respectively. Standardized measurements were taken with the subject lying prone. Initially, the foot and ankle was in a spontaneous, unsupported position. Then passive dorsiflexion was induced by an increasing pressure which was applied in five defined steps against the plantar forefoot. FINDINGS Mean pressures found in unloaded position were 30.5 (SD 28.9) mmHg in retrocalcaneal bursitis and -9.9 (SD 17.2) mmHg in Achilles tendinopathy (p<0.001). A stepwise increase in passive ankle dorsiflexion was associated with increasing pressure values in both groups. The differences were p=0.009 to 0.035 when dorsiflexion was initiated with 10, 20, 30, and 40N, respectively. Dorsiflexion induced by 50N load resulted in a mean pressure of 113.7 (SD 124.9) mmHg for retrocalcaneal bursitis and 32.5 (SD 48.9) mmHg for Achilles tendinopathy (p=0,051). INTERPRETATION Higher retrocalcaneal bursa pressure values were found in patients suffering from chronic retrocalcaneal bursitis. This result supports the hypothesis that retrocalcaneal bursa hypertension leads to an impingement lesion of the corresponding anterior Achilles tendon.

Abstract
Up to now diagnosis of Haglund's disease is based on patient's history and clinical findings. There is no valid diagnostic tool described to functionally detect retrocalcaneal bursitis. Retrocalcaneal bursa pressure may be increased in these patients. We hypothesized that retrocalcaneal bursa pressure can directly be measured. In this pilot investigation we tested the feasibility of a system which is already in clinical use for arterial blood pressure monitoring to quantitatively assess retrocalcaneal bursa pressure in a human and a swine cadaver specimen and in vivo. Using the presented system retrocalcaneal bursa pressure measurement is demonstrated to be feasible. Moreover, intrabursal pressure is reproducibly and validly quantified. In an uninjured subject increasing ankle dorsiflexion was not associated with increasing pressure in the retrocalcaneal bursa. Experimental liquid injection in the retrocalcaneal bursa was associated with increased intrabursal pressure and increasing pain. Feasibility of the tested setup could be proven. The question, if retrocalcaneal bursitis can be distinguished from further heel pathologies by different pressures in the retrocalcaneal bursa has to be addressed in a subsequent in vivo study.

Abstract
Anatomic and operative textbooks and current literature do not clearly describe the Achilles tendon interface to the calcaneal tuberosity. We dissected 51 specimens to identify the detailed anatomy of the Achilles tendon insertion. Achilles tendon fascicles expanded from the anterior aspect of the distal Achilles tendon over the retrocalcaneal bursa to the anterior part of the Haglund's tuberosity in nearly half of the specimens. The insertion of the transverse section of the Achilles tendon regularly had a crescent-shape corresponding to the posterior calcaneal prominence. In transverse sections, all specimens had a curved appearance with a radius of curvature ranging from 13.8 mm to 43.6 mm (mean, 20.4 mm) and Achilles tendon extensions to the lateral and medial calcaneal surfaces reached 1.0 mm (mean) and 3.5 mm (mean) anterior in relation to the most posterior point of the calcaneal tuberosity. Knowledge of the arcuate configuration and of the medial and lateral extensions of the plantaris and the Achilles tendon insertion with respect to the transverse plane is important to avoid iatrogenic complications during resection of Haglund's tuberosity.

Abstract
BACKGROUND About half of patients who have Haglund disease may require treatment by surgical resection of the superior portion of the calcaneal tuberosity. Endoscopic techniques have been described as alternatives to open surgery, but only results of uncontrolled retrospective clinical investigations have been reported. Up to now no research is available which compares these different procedures. METHODS A controlled laboratory study was done to evaluate the morphologic appearance of the superior portion of the calcaneal tuberosity after endoscopic or open resection. The tuberosity was resected in 15 isolated fresh-frozen human cadaver lower limb specimens with either open (nine) or endoscopic (six) technique. Outcome was measured radiographically. Iatrogenic soft-tissue lesions of the distal Achilles tendon, plantaris tendon and sural nerve caused by the surgical procedure were evaluated by direct observation after anatomic dissection. RESULTS Radiographs revealed that the slope of the resection line (osteotomy angle) was steeper (p = 0.017) and the resected protruberance was larger (p = 0.003), while the remaining posterior rim was smaller (p = 0.048) after open resection than after endoscopic resection. Macroscopic analysis indicated that both approaches may damage soft tissues particularly the medial Achilles tendon column and in the plantaris tendon (relative risk = 0.5 in either group). Iatrogenic sural nerve injuries were found after both techniques (relative risk = 0.2 for endoscopic and 0.1 for open resection). Residual bursa tissue was detected only after endoscopy (relative risk = 0.3), while loose bony fragments were present only after open surgery (relative risk = 0.4). CONCLUSIONS AND CLINICAL RELEVANCE The medial column of the Achilles tendon, the plantaris tendon, and the sural nerve are at risk in both open and endoscopic resection for Haglund disease.

Abstract
PURPOSE The aim of this study was to describe typical age-related sonographic features of the Achilles tendon and calcaneal apophysis in children, providing a reference for the assessment of heel pathologies during the growth period. METHODS The calcaneal apophysis and Achilles tendon insertion of 100 children 2 months to 18 years old were examined by high-frequency gray-scale and color Doppler sonography along both the longitudinal and transverse planes. The thicknesses of the apophyseal cartilage at the calcaneal tuberosity and of the Achilles tendon were measured. Also, the sonographic appearance of the bone-cartilage interface was studied. RESULTS In children 2 months to 3 years old, the cartilage of the calcaneal tuberosity apophysis was anechoic, with small scattered echoes. In 19 of these 25 children (76%), the echogenic areas contained at least 1 small vessel, visualized on color Doppler sonography. In 15 of 25 children (60%) 4-6 years old, a wavy interface was noted at the junction of the calcaneus and the apophyseal cartilage. CONCLUSIONS High-frequency sonography can yield reliable information about the bone-cartilage interface and the Achilles tendon insertion site at the calcaneal tuberosity in children. The sonographic features of the normal heel described here may contribute to improved assessment of pathologies in this anatomic region.
