Radiological angle assessment of Haglund's deformity: validation on Magnetic Resonance Imaging. Foot (Edinb) 2024; 59:102096. [PMID: 38626577 DOI: 10.1016/j.foot.2024.102096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 04/07/2024] [Accepted: 04/09/2024] [Indexed: 04/18/2024]
Abstract
PURPOSE Haglund's deformity, an abnormality at the postero-superior corner of the calcaneus is a common cause of posterior heel pain. To date numerous measurements of radiological angles related to the calcaneus have been proposed to differentiate between symptomatic and asymptomatic patients with the deformity. Traditionally, these measurements have been assessed on plain radiographs. The aim of this study was to identify measurements which can be applied to Magnetic Resonance Imaging (MRI) studies of the ankle. METHODS A retrospective cohort analysis of 30 MRI ankle studies from patients with symptomatic Haglund's deformity and 32 normal studies as controls was undertaken. The angle of BRINK, the Achilles angle, Calcaneal pitch, Achilles-plantar fascia angle and soleus calcaneal distance were measured on optimal T2 fat-saturated sagittal slices. RESULTS There was a statistically significant difference (p < 0.0001) in the angle of BRINK between the Haglund's and control group. The Area-Under-the-Curve (AUC) was 0.7783 in keeping with good discrimination between the two groups. The angle of BRINK measurement is reproducible, with an intra-observer ICC of 0.837 and an inter-observer ICC of 0.824. There was no statistically significant difference between the two groups for the other measurements. In the Haglund's group the Achilles tendon was more likely to attach to the mid 1/3 of the posterior calcaneus as opposed to the superior 1/3 (p = 0.02), calcaneal oedema was more likely to be present (p < 0.001) and non-insertional tendinopathy was more likely to be present (p < 0.001). The presence of a retrocalcaneal bursa is non-specific (p = 0.602). CONCLUSION The angle of BRINK demonstrates good discrimination between normal and Haglund's cases on MRI studies and may improve patient management by supporting surgical decision-making. Future work should correlate the angle of BRINK to long-term outcomes.

The effect of the simulated intrauterine sound on behavioral and physiological indices of pain during capillary blood sampling for screening preterm infants: a randomized clinical trial study. BMC Pediatr 2024; 24:110. [PMID: 38350923 PMCID: PMC10863201 DOI: 10.1186/s12887-024-04604-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Accepted: 01/30/2024] [Indexed: 02/15/2024] Open
Abstract
INTRODUCTION Due to medical procedures, preterm infants are at high risk for side effects of pain. In this regard, heel lancing for capillary blood sampling is a common painful procedure. The present study was conducted to assess the effectiveness of a simulated intrauterine sound on behavioral and physiological indices of pain due to heel-prick blood sampling in preterm infants. METHODS A double‑blind randomized clinical trial (RCT) was conducted. The data were collected from September 23 to December 22, 2019. We measured the effect of a simulated intrauterine sound on changes in the behavioral and physiological parameters of pain (heart rate, SPO2) caused by heel lance that was measured 5 min before the intervention, during the sampling, and 5 min after the procedure. We measured behavioral pain by video recording the infants' faces and then the scoring neonatal infant pain scale (NIPS). Heart rate and SPO2 were measured using a pulse oximeter device. The data were analyzed using analysis of variance (ANOVA) and independent t‑test in SPSS software version 20.0. RESULTS Eighty infants were randomized (40 in each group). Mean scores NIPS during and after intervention were in the intervention group (3.55 ± 0.84, 95% CI: 3.30-3.80(, and (1.15 ± 0.84, 95%: 0.95-1.35) and in the control group (5.57 ± 0.95, 95% CI:5.30-5.85) and (3.00 ± 0.98) respectively. There were significant differences in scores of NIPS between the two study groups during (p < 0.001) and five min after heel lancing (p < 0.001). Mean scores of heart rate in the three phases of before, during, and five min after the intervention were respectively in the intervention group (127.57 ± 4.45, 95% CI:126.27-128.99), (131.07 ± 6.54, 95% CI:129.20-133.22), (128.45 ± 5.15, 95% CI:127.02-130.07) and in the control group (128.67 ± 4.57, 95% CI:127.32-130.07), (136.07 ± 7.24, 95% CI:133.90-138.37), and (132.42 ± 6.47, 95% CI:130.37-134.49). There were significant differences in heart rate between the intervention and the control group during (p = 0.002) and five min after the heel lance (p = 0.003). Mean scores of SPO2 in the three phases of baseline, during, and five min after the intervention were respectively in the intervention group (96.72 ± 0.93, 95% CI:96.42-97.00), (91.47 ± 1.46, 95% CI:91.05-91.92), (94.17 ± 1.03, 95% CI:93.22-94.00) and in the control group (96.6 ± 0.84, 95% CI:96.35-96.85), (91.5 ± 1.24, 95% CI:91.12-91.87), and (93.60 ± 1.27, 95% CI:93.85-94.50). CONCLUSION This study showed that the simulated intrauterine sound reduces the behavioral pain and heart rate in the intervention group during and after heel lance. These results suggest using the method during the painful heel lancing to reduce pain parameters in preterm infants.

"Antero-medial load shift" in unilateral plantar heel pain - A cross-sectional exploratory study. J Bodyw Mov Ther 2024; 37:151-155. [PMID: 38432798 DOI: 10.1016/j.jbmt.2023.11.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 09/20/2023] [Accepted: 11/15/2023] [Indexed: 03/05/2024]
Abstract
BACKGROUND AND PURPOSE Plantar foot pressure provides an insightful data in the ankle and foot complex which may aid in the detection of underlying pathology. Since individuals with unilateral plantar heel pain (PHP) tend to develop compensatory loading strategies, this study aimed to observe the foot loading pattern compared to the asymptomatic side and its relationship with the morphological variations in individuals with unilateral PHP. METHODS It was a prospective cross-sectional study done on 17 participants with unilateral PHP. The calcaneal inclination and calcaneal first metatarsal angles were measured using lateral weight-bearing radiographs for both symptomatic and asymptomatic feet. Static and dynamic plantar foot pressures for both sides were obtained using a "Portable baropodometry platform 0, 5 m Entry Level footscan®. RESULTS On the symptomatic side, the pressure in the lateral heel was reduced by 65% in static and 67% in dynamic measurements, while in the medial heel, it was reduced by 16 % in static and 47 % in dynamic measurements compared to that of the asymptomatic side. There was a transfer of pressure from the hind foot to the forefoot by 44 % in static and 46 % in dynamic measurements resulting in anterior load shift. It was also observed that the prevalence of PHP was higher in the normal arched foot (59%). CONCLUSION Based on the observations, compared to the asymptomatic side, patients with unilateral plantar heel pain exhibited an anteromedial load shift (AMLS) in their plantar pressures. PHP was reported higher in the foot with normal morphology. LEVEL OF EVIDENCE Level 4.

Anatomical study of the medial calcaneal nerve using high-resolution ultrasound. Eur Radiol 2023; 33:7330-7337. [PMID: 37209124 DOI: 10.1007/s00330-023-09699-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 02/10/2023] [Accepted: 02/26/2023] [Indexed: 05/22/2023]
Abstract
OBJECTIVES To determine whether high-resolution ultrasound (US) can identify the course and relations of the medial calcaneal nerve (MCN). METHODS This investigation was initially undertaken in eight cadaveric specimens and followed by a high-resolution US study in 20 healthy adult volunteers (40 nerves) by two musculoskeletal radiologists in consensus. The location and course of the MCN as well as its relationship to adjacent anatomical structures were evaluated. RESULTS The MCN was consistently identified by US along its entire course. The mean cross-sectional area of the nerve was 1 mm2 (range 0.5-2). The level at which the MCN branched from the tibial nerve was variable, located a mean of 7 mm (range - 7-60) proximal to the tip of the medial malleolus. At the level of the medial retromalleolar fossa, the MCN was located inside the proximal tarsal tunnel a mean of 8 mm (range 0-16) posterior to the medial malleolus. More distally, the nerve was depicted in the subcutaneous tissue at the surface of the abductor hallucis fascia with a mean direct distance to the fascia of 1.5 mm (range 0.4-2.8). CONCLUSIONS High-resolution US can identify the MCN at the level of the medial retromalleolar fossa, as well as more distally in the subcutaneous tissue at the surface of the abductor hallucis fascia. In the setting of heel pain, precise sonographic mapping of the MCN course may enable the radiologist to make diagnosis of nerve compression or neuroma, and perform selective US-guided treatments. CLINICAL RELEVANCE STATEMENT In the setting of heel pain, sonography is an attractive tool for diagnosing compression neuropathy or neuroma of the medial calcaneal nerve, and enables the radiologist to perform selective image-guided treatments such as diagnostic blocks and injections. KEY POINTS • The MCN is a small cutaneous nerve which rises from the tibial nerve in the medial retromalleolar fossa to the medial side of the heel. • The MCN can be depicted by high-resolution ultrasound along its entire course. • In the setting of heel pain, precise sonographic mapping of the MCN course may enable the radiologist to make diagnosis of neuroma or nerve entrapment, and perform selective ultrasound-guided treatments such as steroid injection or tarsal tunnel release.

Spare part's free contralateral medial plantar flap for emergency reconstruction in a bilateral lower legs ballistic trauma. ANN CHIR PLAST ESTH 2023; 68:364-367. [PMID: 36463025 DOI: 10.1016/j.anplas.2022.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 10/10/2022] [Accepted: 10/24/2022] [Indexed: 12/02/2022]
Abstract
The medial plantar flap is frequently used in heel reconstruction and has been described since 1969. We took care of a 25-year-old patient with a bilateral ballistic trauma and open fractures to the distal third of both legs. Given the seriousness of the damage to the left lower limb, a trans-tibial amputation had to be performed. Concerning the right lower limb, we decided to cover the defect with a spare part's free medial plantar flap thanks to the amputated fragment. The extremity spare tissues principle is already known and described, more particularly concerning hands, in emergency traumatic surgery and in planned surgery, mainly concerning thumb reconstruction, for example for hypoplasia or after traumatic amputation. Apart from an article on the use of foot spare part in the coverage of amputation stumps, no article has reported the use of a foot spare part in reconstructive surgery, even more in traumatic surgery. We believe that the use of an extremity spare tissues should be considered in rare cases where this is possible, in order to reduce donor-site morbidity in the context of reconstructive surgery.

Angle of BRINK - a new way to measure Haglund's deformity. Skeletal Radiol 2023; 52:193-198. [PMID: 36044055 DOI: 10.1007/s00256-022-04169-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Revised: 08/19/2022] [Accepted: 08/19/2022] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Haglund's deformity, an abnormality of the postero-superior corner of the calcaneum, is a common, critically debated cause of posterior heel pain. Several radiological indices such as Fowler-Philip angle, Ruch pitch, Chauveaux-Liet angle, calcaneal pitch angle, parallel pitch lines, and X-Y ratio have been described to measure this deformity. However, most of these lack specificity and have variable intra- and inter-observer reliability. PURPOSE The study aims to describe a new radiological "angle of BRINK" (Botchu-Reilly-Iyengar-Nischal-Kakarala) to measure Haglund's deformity. PATIENT AND METHODS We performed a retrospective cohort analysis, assessing 20 weight-bearing lateral ankle radiographs of patients with Haglund's deformity (Haglund's cohort) and 100 radiographs without the deformity (normal cohort). Demographic details and angle of BRINK to measure Haglund's deformity were measured for each patient. Statistical analysis was performed using t-test and inter-observer reliability was calculated using kappa coefficient. RESULTS The mean angle of BRINK to measure Haglund's deformity in the normal cohort was 20.04° (SD 4.88), and in the Haglund's cohort was 25.1° (SD 3.3). This was statistically significant with a p-value of less than 0.0001. There was excellent intra- and inter-observer reliability with kappa value of 0.8. CONCLUSION Our proposed radiological angle of BRINK to measure Haglund's deformity is simple and easy to calculate on standard weight-bearing radiographs. Contrary to the traditional measurements used to estimate the deformity, it has shown a good intra- and inter-observer reliability and can support surgical decision-making process for management of patients with symptomatic Haglund's deformity.

Total calcaneal reconstruction using a massive bone allograft and a distally pedicled osteocutaneous fibula flap: A novel technique to prevent amputation after calcaneal malignancy. J Plast Reconstr Aesthet Surg 2023; 76:44-48. [PMID: 36516510 DOI: 10.1016/j.bjps.2022.10.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Revised: 07/23/2022] [Accepted: 10/11/2022] [Indexed: 12/14/2022]
Abstract
In patients with primary calcaneal malignancies, such as Ewing's sarcoma, radical treatment with amputation of the foot can result in serious functional impairment and chronic pain. Total calcanectomy followed by the reconstruction of the calcaneal defect offers an alternative treatment to amputation. Capanna et al. described a technique for successfully reconstructing long limb segmental bone defects using a free fibula flap placed within the intramedullary canal of an allograft. We present both a review of the literature on calcaneal reconstruction and describe how the principles of Capanna can be adapted to reconstruct the calcaneus. Total calcanectomy due to Ewing's sarcoma and the subsequent application of this novel reconstructive technique was performed in two young patients aged 5 and 16 years. The reconstruction was achieved by inserting a distally pedicled osteocutaneous fibula flap within the reamed canal of an allograft and placing the composite in the calcaneal defect. Reconstruction was successful with complete bone union between the allograft and the adjacent bone. There were no fractures or infections and both flaps survived. Functional outcome was assessed with a physiotherapist at a follow-up period of 2 years postoperatively, showing near-normal ambulance. This novel technique proved excellent as a limb salvage procedure, avoiding amputation, and offering a satisfactory oncological and functional outcome.

Application of Biomechanics in Treating the Athlete: The All Important Measurements of Relaxed Calcaneal Stance Position, Achilles Flexibility, and First Ray Range of Motion. Clin Podiatr Med Surg 2023; 40:97-115. [PMID: 36368850 DOI: 10.1016/j.cpm.2022.07.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/18/2022]
Abstract
Biomechanics is a crucial component of treating lower extremity pathology. The relaxed calcaneal stance position, the Achilles flexibility, and the first ray motion and position tests are demonstrated and should be mastered. The relaxed calcaneal stance position is crucial in children's flat feet treatment, adult acquired flat feet, and all pronatory symptoms. The Achilles flexibility measurement demonstrates normality, tightness, or overflexibility. Tightness and overflexibility denote weakness owing to the contractile properties of the tendon. The first ray motion and position examination elucidates whether the first ray is normal or part of a pronatory problem or a supinatory problem.

Abstract
Objectives Quantitative ultrasound (QUS) is a bone densitometry method that is less expensive and more portable than DXA. It is also noninvasive. QUS parameters include speed of sound (SOS), broad band ultrasound attenuation (BUA), and stiffness index (SI). This study defined normal values of QUS parameters in Iranian men and women. Methods QUS of heels measured in 258 Iranian men and women, aged 20-76 y/o. They were participants of Iranian Multicenter Osteoporosis study (IMOS), selected by randomized sampling. QUS device was an Achilles+ (GE-Lunar) device. Results Percentiles of SI (2.5%, 50%, and 97.5%) determined. We found a good agreement between the Iranian reference values and western reference (used by device) value in defining normal and osteoporotic people (κ = 0.875). Conclusion Results from this study suggest that QUS of the heel may be a good method for diagnosis of low bone mass in different regions.

Abstract
Background Plantar heel pain (PHP), or plantar fasciopathy, is a common condition in active and sedentary populations, contributing to short- and long-term reductions in quality of life. The condition's aetiology and pathophysiology are the subjects of a significant body of research. However, much of this research has been conducted with sedentary participants, and comparatively little research exists in a population of highly-trained athletes focused on performance outcomes. Models for PHP and proposed mechanisms, such as high body mass index or systemic disease, are mostly absent from an athletic population. Even less is known about the origins of pain in PHP. Pain is believed to be a complex multifactorial process and may be experienced differently by sedentary and highly active populations, particularly endurance athletes. Consequently, conservative through to surgical treatment for athletes is informed by literature for a different population, potentially hindering treatment outcomes. Aims The aim of this review, therefore, is to summarise what is known about PHP in athletic populations and propose potential directions for future research. Methods Embase, PubMed, and Scopus using MeSH search terms for PHP and competitive sport and common synonyms. Discussion Two explanatory models for PHP were found. These primarily propose mechanical factors for PHP. It remains unclear how gait, body composition, and psychological factors may differ in an athletic population with and without PHP. Therefore, research in these three areas is needed to inform clinical and training interventions for this population.

Abstract
Objective To investigate the imaging characteristics and clinically assess heel enthesitis in spondyloarthritis (SpA) by applying in a post hoc analysis the Heel Enthesitis Magnetic Resonance Imaging Scoring system (HEMRIS) in blinded and centrally-read MRI data from the ACHILLES trial (NCT02771210). Methods ACHILLES included patients (≥18 years) with active psoriatic arthritis or axial SpA with clinical and MRI-positive heel enthesitis refractory to standard treatment. Patients were randomized to receive subcutaneous secukinumab 150/300 mg or placebo. At week 24, patients on placebo were switched to secukinumab treatment. MRI-positive heel enthesitis was confirmed in all patients by local investigators. MRIs were performed at 3 timepoints: screening and weeks 24 and 52. In the present analysis, all MRIs were re-evaluated by 2 blinded central readers in a consensus read fashion for a priori defined MRI parameters based on HEMRIS. Results At screening, 171/204 (83.8%) of patients presented with entheseal inflammation and/or structural damage, considering both the Achilles tendon and plantar fascia. Pathologies were more evident in the Achilles tendon area compared to the plantar aponeurosis. The most frequent pathologies were intra-tendon hypersignal and retrocalcaneal bursitis. The mean total entheseal inflammation score at screening in the Achilles tendon area was 2.99 (N=204) and the mean change (standard deviation [SD]) from screening to weeks 24 and 52 was − 0.91 (1.99) and − 0.83 (2.12) in the secukinumab group vs − 0.48 (1.86) and − 0.80 (1.98) in the placebo-secukinumab group, respectively. The mean total structural damage score at screening was 1.36 (N=204) and the mean change (SD) from screening to weeks 24 and 52 was 0.00 (0.65) and − 0.06 (0.56) in the secukinumab group vs 0.08 (0.48) and 0.04 (0.75) in the placebo-secukinumab group, respectively. Conclusions Based on the newly developed HEMRIS, entheseal inflammation and/or structural damage was confirmed in 83.3% of ACHILLES patients. Pathologies were more evident in the Achilles tendon area compared to plantar fascia, with the inflammatory parameters being more responsive with secukinumab treatment compared to placebo. The present analysis, with detailed information on individual MRI parameters, contributes to the scientific debate on heel enthesitis. Trial registration ClinicalTrials.gov NCT02771210.

Abstract
Background Calcaneal apophysitis, or Sever's disease, is the most common cause of heel pain in childhood and adolescence. It is regarded as an overuse syndrome. Studies on the incidence of calcaneal apophysitis in young athletes and their associated return-to-play time are lacking in the current literature. The aim of our current study was to identify the incidence of calcaneal apophysitis in professional youth soccer, the associated time to return-to-play, predisposing factors and their impact on time to return-to-play.
Methods Retrospective evaluation of injury data gathered from a German youth soccer academy in the years 2009–2018. In total, 4326 injury cases in 612 players were included in the study. The diagnosis and the follow-up visits were carried out in a weekly consultation hour at the youth academy. Results During the observation period of 10 years, 22 cases of calcaneal apophysitis were detected. The incidence of calcaneal apophysitis per 100 athletes per year was found to be 0.36. The mean age of the affected athletes at the time of diagnosis was 11.8 ± 2.1 years (MW ± SD). The complaints were unilateral in 20 and bilateral in two cases. Three of the 22 detected cases of calcaneal apophysitis (13.6%) were recurrent injuries. The mean time to return-to-play of the affected athletes was 60.7 ± 64.9 days (MW ± SD). Athletes with recurrent complaints showed longer recovery time and time to return-to-play when compared to players with primary diagnosed disease. Our results could show that neither age nor body mass index at the time of diagnosis had an impact on time to return-to-play. Conclusions This is the first study investigating the incidence of calcaneal apophysitis and the associated time to return-to-play in youth elite soccer. Calcaneal apophysitis results in substantial time loss for the athletes. Further prospective clinical studies are required to fully understand the etiology and risk factors for calcaneal apophysitis and therefore develop preventive strategies.

Is Real-Time Ultrasound Reliably Able to Determine Kager's Fat Pad Motion during Walking? ULTRASOUND IN MEDICINE & BIOLOGY 2022; 48:217-222. [PMID: 34742596 DOI: 10.1016/j.ultrasmedbio.2021.09.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Revised: 09/28/2021] [Accepted: 09/29/2021] [Indexed: 06/13/2023]
Abstract
The distal calcaneal wedge of the Kager's fat pad (KFP) has the mechanical role of lubricating the region between the Achilles tendon and calcaneus during ankle movements. The purpose of this study was to determine the reliability of real-time ultrasound (RTUS) in visualizing the motion of the KFP during walking in adults. Recordings obtained using RTUS (13-MHz linear array transducer, IOE 323, MyLab 70, Esoate, Genoa, Italy) of the Achilles enthesis region (N = 52) of 47 participants (ranging from 21-79 years in age) while walking on a motorised treadmill at their preferred speed were analysed by three blinded assessors. Motion of the KFP was rated on a 4-point Likert scale (normal to absent). There was good agreement (κ [95% confidence interval] = 0.646 [0.643-0.649]) among the three examiners, with very good agreement (0.823 [0.818-0.828]) when classifying the motion as normal. There was a poor correlation between the motion of the calcaneal wedge and participants' age (0.23-0.32). RTUS provides an adjunct to routine clinical examination to determine if there is normal motion of the calcaneal wedge during walking. This may be of benefit in patients with posterior heel pain for whom abnormal KFP motion is implicated.

Risk factors associated with heel pressure ulcer development in adult population: A systematic literature review. J Tissue Viability 2021; 31:84-103. [PMID: 34742635 DOI: 10.1016/j.jtv.2021.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 09/29/2021] [Accepted: 10/22/2021] [Indexed: 12/01/2022]
Abstract
AIMS The main aim of this systematic literature review was to identify risk factors for development of heel pressure ulcers and quantify their effect. BACKGROUND Pressure ulcers remain one of the key patient safety challenges across all health care settings and heels are the second most common site for developing pressure ulcers after the sacrum. DESIGN Quantitative systematic review. METHODS Data sources: Electronic databases were searched for studies published between 1809 to March 2020 using keywords, Medical Subject Headings, and other index terms, as well as combinations of these terms and appropriate synonyms. STUDY ELIGIBILITY CRITERIA Previous systematic literature reviews, cohort, case control and cross-sectional studies investigating risk factors for developing heel pressure ulcers. Only articles published in English were reviewed with no restrictions on date of publication. PARTICIPANTS patients aged 18 years and above in any care setting. Study selection, data extraction, risk of bias and quality assessment were completed by two independent reviewers. Disagreements were resolved by discussion. RESULTS Thirteen studies met the eligibility criteria and several potential risk factors were identified. However, eligible studies were mainly moderate to low quality except for three high quality studies. CONCLUSIONS There is a paucity of high quality evidence to identify risk factors associated with heel pressure ulcer development. Immobility, diabetes, vascular disease, impaired nutrition, perfusion issues, mechanical ventilation, surgery, and Braden subscales were identified as potential risk factors for developing heel pressure ulcers however, further well-designed studies are required to elucidate these factors. Other risk factors may also exist and require further investigation. PROSPERO ID PROSPERO International prospective register of systematic reviews: CRD42017071459.

A problem-based approach in musculoskeletal ultrasonography: heel pain in adults. Ultrasonography 2021; 41:34-52. [PMID: 34674456 PMCID: PMC8696136 DOI: 10.14366/usg.21069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 06/29/2021] [Indexed: 11/24/2022] Open
Abstract
Musculoskeletal ultrasonography (US) has unique advantages, such as excellent spatial resolution for superficial structures, the capability for dynamic imaging, and the ability for direct correlation and provocation of symptoms. For these reasons, US is increasingly used to evaluate problems in small joints, such as the foot and ankle. However, it is almost impossible to evaluate every anatomic structure within a limited time. Therefore, US examinations can be faster and more efficient if radiologists know where to look and image patients with typical symptoms. In this review, common etiologies of heel pain are discussed in a problem-based manner. Knowing the common pain sources and being familiar with their US findings will help radiologists to perform accurate and effective US examinations.

Effects of skin moisturizer on the skin barrier dysfunction model: An evaluation of the heel via tape-stripping in healthy, young adults. J Tissue Viability 2021; 30:439-445. [PMID: 33632568 DOI: 10.1016/j.jtv.2021.02.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Revised: 01/06/2021] [Accepted: 02/02/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND This study seeks to establish the skin barrier dysfunction model at the heel via tape-stripping (TS) by evaluating the skin moisturizing effects. MATERIALS AND METHODS Nineteen young, female participated in the study. A sequence of TS was performed at the heel and trans-epidermal water loss (TEWL), stratum corneum (SC) hydration, and surface pH were measured. Following TS, the subjects were divided into three groups: moisturizer, emollient, and overcoat. These agents were applied daily at night, and the skin parameters were measured the next morning for a week. RESULTS The TEWL value of TS immediately and 5 min after TS were significantly higher than what was obtained before TS, while the SC hydration after TS was significantly lower than what was obtained before TS. However, there were no significant differences in the skin parameters among the three agents on day 7 after application, with the two-way ANOVA showing no interaction among the agents and number of days. CONCLUSION The skin barrier dysfunction model at the heel was established by TS in healthy, young adults. However, the physiological function of the skin at the heel did not change drastically and showed no differences even after continuous application for 7 days.

Long-term effect and prognostic factors of a low-dose radiotherapy of painful plantar calcaneal spurs : A retrospective unicenter study. Strahlenther Onkol 2021; 197:876-884. [PMID: 33502569 DOI: 10.1007/s00066-020-01741-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2020] [Accepted: 12/24/2020] [Indexed: 11/29/2022]
Abstract
PURPOSE To estimate the long-term effect of low-dose radiotherapy of painful plantar calcaneal spurs, and to verify possible prognostic factors. PATIENTS AND METHODS In this retrospective unicenter study, electronic patient files of patients with painful plantar calcaneal spurs treated with low-dose radiotherapy between July 2009 and February 2020 were reviewed. The low-dose radiotherapy consisted of a total dose of 3.0 Gy given with a fraction dose of 0.5 Gy three times a week. The pain reduction was estimated using a patient questionnaire with a visual analogue scale. Kaplan-Meier statistics and Cox regression analysis were used for the statistical analysis. RESULTS Altogether, 864 heels of 666 patients were reviewed. The probability of an insufficient pain control 10 years after low-dose radiotherapy was 45.9% (95% confidence interval 39.4-52.4%) in the subset of patients with a minimum follow-up of 3 months (582 heels of 467 patients). Patients with an unsatisfactory pain reduction 3 months after low-dose radiotherapy were offered a re-irradiation. Forty percent of the patients who received a re-irradiation developed good pain reduction. Occurrence of an initial aggravation of pain during or within 3 months after low-dose radiotherapy (p = 0.005), and treatment of bilateral painful plantar calcaneal spurs (p = 0.008) were identified as significant unfavorable prognostic factors on univariate analysis. On multivariate analysis, the initial aggravation of pain remained as independent significant prognostic factor (p = 0.01). No clear radiation toxicity was observed. CONCLUSIONS Low-dose radiotherapy is a safe and effective treatment option for patients with painful plantar calcaneal spurs. An initial aggravation of pain during or within 3 months after radiotherapy was identified as unfavorable prognostic factor for the treatment outcome. Re-irradiation of patients with an unsatisfactory pain reduction after low-dose radiotherapy is effective and should be offered to patients.

Abstract
The calcaneum is the most inferior and largest tarsal bone and supports the axial load of the weight of the body. Calcaneal fractures formulate 60% of the tarsal fractures and are frequently encountered in almost all trauma centres. It becomes imperative to understand and report calcaneal fractures in a structured fashion for better clinical and treatment outcomes for the patients. Radiologists should be well acquainted with calcaneal fractures and their various classifications and should develop an algorithmic approach for diagnosing and reporting heel fractures.

Abstract
Acquired digital fibrokeratomas are a benign soft tissue tumor with typical appearance and anatomical locations. This lesion generally occurs in middle aged males with common sites of occurrence in the digits of upper or lower extremities. Previous case studies have reported incidences of this lesion appearing on heels of middle-aged males but are generally described as giant digital fibrokeratoma based on the lesion's diameter. This case report describes an acquired digital fibrokeratoma in a pediatric female patient in an infrequent location.

Paediatric calcaneal fractures: A guide to management based on a review of the literature. Injury 2020; 51:1432-1438.

Abstract
INTRODUCTION Calcaneal fractures are rare in children. These fractures are often misdiagnosed as a consequence of their subtle clinical and radiographic presentation. The purpose of this paper was to identify prognostic factors on the basis of type of fracture, age and treatment. This would enable suggestions to be made with regards to treatment for these fractures. METHODS A full literature search was performed to find studies that were clinically orientated, in the English language and involved children (under the age of 16). Studies with no outcome data were excluded. RESULTS There were a total of 284 patients reviewed in 26 peer-review publications. Two hundred and eight patients had intra-articular fractures. The non-operatively managed joint depression type fractures had poor outcomes in 21% of patients. In those who underwent surgical fixation for these fractures, 3 patients had reduced subtalar motion, and three had pain, one of whom required a subtalar arthrodesis at 7 months. In the tongue type fracture group, the outcomes were similar in those treated operatively and non-operatively. Extra-articular fractures were found to be much less common than the intra-articular fractures. They also became less common in older children. Generally, the outcomes were good, irrespective of treatment. Only 2 patients with type 1B fractures had poorer outcomes. DISCUSSION This is a rare injury and outcomes may be poorer in those who do not have adequate anatomical reduction. Displaced intra-articular fractures in all age groups should be considered for anatomical reduction of the articular surface, to guarantee good outcomes and prevent future pain and arthritis. Extra-articular fractures in children are less severe, do well with conservative treatment, and rarely require operative intervention.

Two-staged reverse sural flap: a versatile flap with consistent results in the soft tissue reconstruction of distal leg and heel defects-an institutional experience. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2019; 30:337-341. [PMID: 31473822 DOI: 10.1007/s00590-019-02544-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2019] [Accepted: 08/29/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Reverse sural flap (RSF) is commonly used for soft tissue reconstruction of distal leg and heel defects. The classic method of flap transfer is the single-staged cutaneous islanded reverse sural flap (SS-RSF). This method is associated with variable flap complications notably the venous congestion. The other form of flap transfer is the two-stage reverse sural flap (TS-RSF), in which the pedicle of the flap is exteriorized in the first stage. Flap division and re-inset are done in the second stage. The aim of this paper is to review the flap outcomes and complications among the SS-RSF and TS-RSF reconstruction of soft tissue defects in the distal leg and heel. METHODS This is a retrospective chart review of RSF being operated in a tertiary care hospital. The duration of study was 1.5 years. Twelve RSFs (6 SS-RSF, 6 TS-RSF) were done for soft tissue defects in the distal leg and heel. Wounds of various etiologies (traumatic, chronic, non-healing ulcers) were reviewed. Trauma was the most common etiology with 8 out of 12 (66.7%) patients. Large wounds, donor site damage and patients with peripheral vascular disease were excluded from the study. RESULTS Five out of six (83.3%) of TS-RSF healed uneventfully. However, 3 out of 6 (50%) of SS-RSF had partial flap necrosis. All complicated flaps healed well subsequently. No donor site complication was found in any of our patients. CONCLUSION Pedicle exteriorization in TS-RSF eliminates the element of venous congestion and eventually flaps necrosis. Less technical expertise and minimal morbidity are additional advantages of TS-RSF. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Objective: To explore the clinical effects of heel lateral flap in repair of skin and soft tissue defects at posterior heel region. Methods: From September 2007 to April 2016, 24 patients (17 males and 7 females, aged 16-70 years) with skin and soft tissue defects at posterior heel region were admitted to our department. The size of skin and soft tissue defects after debridement ranged from 3.0 cm×2.0 cm to 5.0 cm×4.0 cm. The defects were repaired with heel lateral flaps, with size ranging from 3.5 cm×2.5 cm to 6.0 cm×5.0 cm. The flaps were transferred to the donor sites through the loose subcutaneous tunnel. The donor site was repaired by full-thickness skin graft collected from inguinal region. The survival of flaps and the follow-up of patients were observed. Results: All flaps of 24 patients survived successfully. The recipient sites and donor sites were all healed. The patients all had follow-up of 6 to 24 months. At the last follow-up, the flaps were in good shape, with nearly normal color and soft texture. There were 6 cases of grade S3 sensation and 16 cases of grade S3(+) sensation. The distance of two-point discrimination of flaps ranged from 6 to 11 mm. The lateral foot skin grafts healed well, and the skin of the lateral foot was numb in the range of 4.0 cm×2.0 cm to 9.0 cm×3.0 cm. Conclusions: Heel lateral flap can not only repair the skin and soft tissue defects in the posterior region, but also reconstruct the sensory function of the posterior region. It is an ideal method to repair the skin and soft tissue defects in the posterior region.

Abstract
Objective To investigate and compare the effect of low-dye taping (LDT) and figure-8 modification of LDT (MLDT) on peak plantar pressure and heel pain in patients with heel pad atrophy. Methods There were reviewed 32 feet of 19 patients who have been diagnosed with heel pad atrophy who were enrolled in this study. The patients were diagnosed with heel pad atrophy with clinical findings, and loaded heel pad thickness measured by ultrasonography. At the first visit, patients were taught how to do LDT and MLDT. They were instructed to do daily living with barefoot, LDT and MLDT at least one time per day. Patients performed pedobarography with barefoot, LDT and MLDT within 2 weeks. The severity of heel pain was also checked with the visual analogue scale (VAS) during daily living with barefoot, LDT and MLDT. Results VAS of hindfoot were significantly decreased after LDT and MLDT (p<0.01). Peak plantar pressure under hindfoot were also decreased after LDT and MLDT (p<0.01). The effect of MLDT in decreasing peak plantar pressure of hindfoot (p<0.01) and pain relief (p=0.001) was better than the effect of LDT. Conclusion The LDT technique is clinically useful for pain management and reducing peak plantar pressure of hindfoot in patients with heel pad atrophy. MLDT is more effective than LDT in reducing peak plantar pressure and heel pain in patients with heel pad atrophy.

Abstract
Objective To investigate the differences in biomechanical parameters measured by gait analysis systems between healthy subjects and subjects with plantar fasciitis (PF), and to compare biomechanical parameters between ‘normal, barefooted’ gait and arch building gait in the participants. Methods The researchers evaluated 15 subjects (30 feet) with bilateral foot pain and 15 subjects (15 feet) with unilateral foot pain who had a clinical diagnosis of PF. Additionally, 17 subjects (34 feet) who had no heel pain were recruited. Subjects were excluded if they had a traumatic event, prior surgery or fractures of the lower limbs, a leg length discrepancy of 1 cm or greater, a body mass index greater than 35 kg/m2, or had musculoskeletal disorders. The participants were asked to walk with an arch building gait on a treadmill at 2.3 km/hr for 5 minutes. Various gait parameters were measured. Results With the arch building gait, the PF group proved that gait line length and single support line were significantly decreased, and lateral symmetry of the PF group was increased compared to that of the control group. The subjects with bilateral PF displayed significantly increased maximum pressure over the heel and the forefoot during arch building gait. In addition, the subjects with unilateral PF showed significantly increased maximum pressure over the forefoot with arch building gait. Conclusion The researchers show that various biomechanical differences exist between healthy subjects and those with PF. Employing an arch building gait in patients with PF could be helpful in changing gait patterns to normal biomechanics.

Abstract
Objective To study use of the medial plantar flap for reconstruction of the heel and foot. Method The authors share their clinical experience with the use of the medial plantar artery flap for coverage of tissue defects around the foot and heel after trauma. Twelve cases of medial plantar artery flap performed from January 2001 to December 2013 were included. Results Of the 12 patients, ten were male and two were female. The indications were traumatic loss of the heel pad in ten cases and the dorsal foot in two cases. All the flaps healed uneventfully without major complications, except one case with partial flap loss. The donor site was covered with a split-thickness skin graft. The flaps had slightly inferior protective sensation compared with the normal side. Conclusion From these results, the authors suggest that the medial plantar artery flap is a good addition to the existing armamentarium for coverage of the foot and heel. It is versatile flap that can cover defects on the heel, over the Achilles tendon and plantar surface, as well as the dorsal foot. It provides tissue to the plantar skin with a similar texture and intact protective sensation.

Abstract
OBJECTIVE To determine the prevalence of heel pain in a series of patients with psoriatic arthritis (PsA). MATERIAL AND METHODS Cross-sectional, observational and retrospective study of a series of 347 patients. All patients fulfilled the CASPAR criteria for PsA and 291 had a clinically significant history of heel pain. The statistical analysis was performed using chi-square test, ANOVA and binary logistic regression. RESULTS Thirty-five percent of the patients had clinically significant heel pain. A significant association was established between an early onset of skin and joint involvement in the disease and the development of heel pain. However, no significant correlation was found between disease duration and the presence of heel pain. History of dactylitis and PsA in first-degree family members was also statistically associated with this complication. CONCLUSIONS Clinically significant heel pain was recorded in one third of the patients in this series. There was a statistically significant association with dactylitis, PsA in first-degree family members and an earlier onset of joint and skin disease.

Abstract
BACKGROUND Large soft tissue defects of ankle and foot always have been challenging to reconstruct. Reverse sural flaps, free flaps have been used for this problem with variable success. Reverse peroneal artery flap is an option to use with reliability without microvascular repair. Connections of peroneal artery around talus and ankle joint are deep and reliable with anterior tibial and posterior tibial artery. Arterial inflow and venous drainage improved with including short saphenous vein and reverse sural artery in the flap. METHODS Ten patients with large defects around heel underwent reconstruction with (RPAF) reverse peroneal artery flap (pedicled) over a period of 2 years. Final inset given after 18-21 days of primary surgery. The mean age of these patients was 45 years. RESULTS Of the 10 flaps, all showed complete survival without even marginal necrosis. Two patients had minor donor site problems that settled with conservative management. CONCLUSION RPAF is a very reliable flap for the coverage of large soft tissue defects of the heel and sole. Large defects can be reconstructed without microvascular surgery and without compromising major vessel of foot region. If some experience with perforator flaps and free fibula is there then RPAF is easy to execute with reliability.

Foot structure is correlated with performance in a single-joint jumping task. J Biomech 2017; 57:27-31.

Abstract
Variability in musculoskeletal structure has the potential to influence locomotor function. It has been shown, for example, that sprinters have smaller Achilles tendon moment arms and longer toes than non-sprinters, and toe length has been found to correlate with toe flexor work in running humans. These findings suggest that interindividual variation in human foot structure allows for function that is adapted to various motor tasks. The purpose of this study was to test for correlations between foot anthropometry and single-joint maximal-height jumping performance. Ten male subjects performed static jumps using only their ankles for propulsion. Several anthropometric measures were taken. Bivariate correlation analyses were performed between all anthropometric variables and the average jump height for each subject. Results showed that the best jumpers had longer lateral heel lengths (r=0.871; p=0.001) and longer toes (r=0.712; p=0.021). None of the other anthropometric variables (stature, mass, lower extremity lengths) measured were found to correlate significantly with jump height. A factor analysis was performed to investigate whether some underlying feature related to body stature could explain jumping performance. Taller subjects did not necessarily jump higher. Specific variations in foot structure, unrelated to other general stature measures, were associated with performance in this single-joint jumping task.

Abstract
PURPOSE To demonstrate the usefulness of rearfoot transcutaneous oximetry to assess the peripheral arterial disease in diabetic patients with heel ulcer. METHODS From our database of 550 critical limb ischemia diabetic patients followed after a percutaneous transluminal angioplasty, we have selected patients with below the knee arterial disease. Patients were grouped according to the dorsal transcutaneous oximetry value (Group A < 30 mmHg; Group B ≥ 30 mmHg). Patients of Group B had a second oximetry performed at the rearfoot, close to the lesion localized in all cases at the heel. Finally, the analysis of the arterial pattern disease has been done. RESULTS We selected 191 patients: Group A (151 patients), dorsal transcutaneous oximetry of 11.8 ± 0.7 mmHg; Group B (40 patients), dorsal transcutaneous oximetry of 44.2 ± 10.1 mmHg. In Group B, rearfoot oximetry was 20.5 ± 5 mmHg, significantly lower than dorsal oximetry (p = 0.0179). The anterior tibial artery was involved in all patients of Group A. In Group B, the anterior tibial artery was involved in 15 subjects and never alone; the posterior tibial artery was involved in 20 subjects and in 11 cases alone. The peroneal artery was affected in 20 subjects and in 14 patients alone. CONCLUSION When a heel lesion is present and the transcutaneous oximetry recorded on the dorsum of the foot does not confirm the presence of critical limb ischemia (not ≤30 mmHg), a second oximetry recorded on the rearfoot is useful to point out ischemia of the peroneal artery and/or of the posterior tibial artery.

J Clin Orthop Trauma 2016; 7:296-301. [PMID: 27857507 PMCID: PMC5106478 DOI: 10.1016/j.jcot.2016.06.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2015] [Revised: 04/30/2016] [Accepted: 06/10/2016] [Indexed: 11/21/2022] Open
Abstract
AIM To determine patient satisfaction in the patients of displaced intraarticular calcaneal fractures treated with standard lateral approach. METHOD The patients of displaced calcaneal fractures (Sander's type II and III) treated between March 2009 and March 2012 were included in the retrospective review and functional outcome was evaluated using American Orthopaedic Foot and Ankle Society (AOFAS) hind foot score, Creighton Nebraska Health Foundation Assessment (CNHFA) scale and foot function index (FFI). RESULT The cohort included 26 patients (19 males: seven were females) with a mean age of 38.16 ± 13.53 years (range 18-64 years). The mean period of follow-up was 24.42 ± 6.68 months. The patients achieved good functional scores after anatomical reduction of the fracture. The complication rate was low following strict inclusion criteria. CONCLUSION Careful patient selection in displaced intraarticular calcaneal fractures treated through lateral extensile approach achieves good patient satisfaction.

Reconstruction of Ankle and Heel Defects with Peroneal Artery Perforator-Based Pedicled Flaps. Arch Plast Surg 2015; 42:619-25. [PMID: 26430635 PMCID: PMC4579175 DOI: 10.5999/aps.2015.42.5.619] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2015] [Revised: 06/20/2015] [Accepted: 06/22/2015] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND The reconstruction of ankle and heel defects remains a significant problem for plastic surgeons. The following options exist for reconstructing such defects: local random flaps, reverse flow island flaps, and free flaps. However, each of these methods has certain drawbacks. Peroneal artery perforators have many advantages; in particular, they are predictable and reliable for ankle and heel reconstructions. In this study, we report our clinical experience with peroneal artery perforator-based pedicled flaps in ankle and heel reconstructions. METHODS From July 2005 to October 2012, 12 patients underwent the reconstruction of soft tissue defects in the ankle and heel using a peroneal artery perforator-based pedicled flap. These 12 cases were classified according to the anatomical area involved. The cause of the wound, comorbidities, flap size, operative results, and complications were analyzed through retrospective chart review. RESULTS The mean age of the patients was 52.4 years. The size of the flaps ranged from 5×4 to 20×8 cm(2). The defects were classified into two groups based on whether they occurred in the Achilles tendon (n=9) or heel pad (n=3). In all 12 patients, complete flap survival was achieved without significant complications; however, two patients experienced minor wound dehiscence. Nevertheless, these wounds healed in response to subsequent debridement and conservative management. No patient had any functional deficits of the lower extremities. CONCLUSIONS Peroneal artery perforator-based pedicled flaps were found to be a useful option for the reconstruction of soft tissue defects of the ankle and heel.

Heel quantitative ultrasound in HIV-infected patients: a cross-sectional study. Infection 2015; 44:197-203. [PMID: 26349915 DOI: 10.1007/s15010-015-0842-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2015] [Accepted: 08/31/2015] [Indexed: 10/23/2022]
Abstract
PURPOSE HIV infection has been associated with increased risk of osteoporosis and fragility fractures. Dual-energy X-ray absorptiometry (DXA) is the reference standard to assess bone mineral density (BMD); however, it is not easily accessible in several settings. Heel Quantitative ultrasound (QUS) is a radiation-free, easy-to-perform technique, which may help reducing the need for DXA. METHODS In this cross-sectional study, we used heel QUS (Hologic Sahara(®)) to assess bone status in a cohort of HIV-infected patients. A QUS stiffness index (QUI) threshold >83 was used to identify patients with a low likelihood of osteoporosis. Moreover, we compared QUS results with those of 36 sex- and age-matched HIV-negative controls. RESULTS 244 HIV-positive patients were enrolled. Median heel QUI value was 83 (73-96) vs. 93 (IQR 84-104) in the control group (p = 0.04). 110 patients (45 %) had a QUI value ≤83. Risk factors for low QUI values were age (OR 1.04 per year, 95 % CI 1.01-1.07, p = 0.004), current use of protease inhibitors (OR 1.85, CI 1.03-3.35, p = 0.039), current use of tenofovir (OR 2.28, CI 1.22-4.27, p = 0.009) and the number of risk factors for secondary osteoporosis (OR 1.46, CI 1.09-1.95, p = 0.01). Of note, QUI values were significantly correlated with FRAX score (r = -0.22, p = 0.004). According to EACS guidelines, 45 % of patients had risk factors for osteoporosis which make them eligible for DXA. By using QUS, we may avoid DXA in around half of them. CONCLUSIONS As HIV-positive patients are living longer, the prevalence of osteoporosis is expected to increase over time. Appropriate screening, prevention and treatment are crucial to preserve bone health in this population. The use of screening techniques, such as heel QUS, may help reducing the need for DXA. Further studies are needed to define the diagnostic accuracy of this promising technique in the setting of HIV.

Abstract
At St Helens and Knowsley Teaching Hospitals NHS Trust, implementation of pressure management measures has reduced the incidence of hospital-acquired pressure ulcers. There is now a focus on those pressure ulcers still occurring despite these measures, particularly grade 2 ulcers on the heel, which are often attributed to friction and shear. During 2012 and 2013 low friction fabric bootees (Parafricta®) were used on at-risk patients (where possible) to attempt to address this issue. The bootees were first introduced in 2012. There was a decline in heel ulcers of 78% in the 2 years, which accounted for a sizeable portion of the overall decline in all grade 2 pressure ulcers. There was also a substantial change in the ratio of heel to all other grade 2 pressure ulcers, which fell from 0.67 to 0.24. On the basis of heel pressure ulcers avoided, there is an implied net saving to the NHS. The trust concluded that routine use of low-friction fabric bootees made a significant further contribution towards achieving zero harm targets and had done so while providing substantial cost benefits.

Large heel soft tissue defects managed successfully with reverse medial crural fasciocutaneous flap: a 7-year single-center experience with 21 consecutive cases. J Plast Reconstr Aesthet Surg 2014; 68:40-8. [PMID: 25448373 DOI: 10.1016/j.bjps.2014.09.041] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2013] [Revised: 08/25/2014] [Accepted: 09/15/2014] [Indexed: 11/16/2022]
Abstract
The medial crural fasciocutaneous flap is a reliable cutaneous flap that can be used for soft tissue reconstruction in the extremities. The purpose of this article is to evaluate the application and clinical significance of this surgical technique in the reconstruction of heel soft tissue defects. Twenty-one cases of heel soft tissue defect between March 2005 and March 2012 were included in this study. Wound sizes varied from 5.0 × 5.5 to 7.5 × 10.0 cm. All cases were managed with a reverse medial crural fasciocutaneous flap. Patient demographics and case information were analyzed and are reported. The sizes of the reverse medial crural fasciocutaneous flap varied from 6.5 × 10.0 to 9.0 × 15.0 cm; the average size was 7.7 × 13.8 cm. Out of the 21 consecutive cases, 20 flaps survived intact and one flap underwent partial necrosis. Follow-up observations were conducted for 6-36 months. The cosmetic results were satisfactory, without apparent bulkiness; the weight-bearing outcomes were satisfactory. The donor site can be closed primarily or by skin graft. Reverse medial crural fasciocutaneous flap transfer is appropriate for the reconstruction of heel soft tissue defects. The method is safe and can cover large heel defects.

Abstract
INTRODUCTION Complex heel injuries in children are rare and their management requires coverage combining resistance and thinness, to allow walking and footwear. The objective of this study was to create a decision-making algorithm for heel defect in children. MATERIALS Children received for heel defect, reconstructed with flap in our plastic surgery unit of Bordeaux with a follow-up greater than 10 years were investigated. Three children operated between 1999 and 2003 were included. A free contralateral reinnervated medial plantar flap, a free latissimus dorsi flap and a lateral supramalleolar flap were performed. Patients were reviewed in consultation to assess quality of reconstruction and functional outcomes. Three scores were used, the Foot Function Index (FFI), the AOFAS Ankle and Hindfoot Scale and the Maryland Foot Score. RESULTS No growth disorder has been found. Scores greater than 80 for the Maryland Foot Score and AOFAS Ankle and Hindfoot Scale and less than 10 for the FFI were very satisfactory in cases 1 and 3. We found pain and greater functional impairment in the second case. CONCLUSIONS "Like-with-like" reconstruction remains the gold standard, whether in loco-regional or free flap. The fasciocutaneous flaps allow custom reliable coverage with little donor site morbidity. Loco-regional flaps remain easily accessible but donor site sequelae are not negligible.

Abstract
This article reviews the role of cavus in foot and ankle injury and summarizes the current surgical and nonsurgical treatments. Recognition of foot position is crucial in the management of ankle instability associated with cavovarus. Correcting foot alignment with orthoses or surgery improves the mechanics of the ankle, reducing the risk of instability and potentially delaying the onset of posttraumatic ankle arthritis. Progressive steps in the correction alignment are described, with technical tips and strategies for dealing with chronic instability.

Diabetic foot ulcer incidence in relation to plantar pressure magnitude and measurement location. J Diabetes Complications 2013; 27:621-6. [PMID: 24012295 PMCID: PMC4227535 DOI: 10.1016/j.jdiacomp.2013.07.004] [Citation(s) in RCA: 83] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2013] [Revised: 07/11/2013] [Accepted: 07/26/2013] [Indexed: 12/12/2022]
Abstract
AIMS We prospectively examined the relationship between site-specific peak plantar pressure (PPP) and ulcer risk. Researchers have previously reported associations between diabetic foot ulcer and elevated plantar foot pressure, but the effect of location-specific pressures has not been studied. METHODS Diabetic subjects (n=591) were enrolled from a single VA hospital. Five measurements of in-shoe plantar pressure were collected using F-Scan. Pressures were measured at 8 areas: heel, lateral midfoot, medial midfoot, first metatarsal, second through fourth metatarsal, fifth metatarsal, hallux, and other toes. The relationship between incident plantar foot ulcer and PPP or pressure-time integral (PTI) was assessed using Cox regression. RESULTS During follow-up (2.4years), 47 subjects developed plantar ulcers (10 heel, 12 metatarsal, 19 hallux, 6 other). Overall mean PPP was higher for ulcer subjects (219 vs. 194kPa), but the relationship differed by site (the metatarsals with ulcers had higher pressure, while the opposite was true for the hallux and heel). A statistical analysis was not performed on the means, but hazard ratios from a Cox survival analysis were nonsignificant for PPP across all sites and when adjusted for location. However, when the metatarsals were considered separately, higher baseline PPP was significantly associated with greater ulcer risk; at other sites, this relationship was nonsignificant. Hazard ratios for all PTI data were nonsignificant. CONCLUSIONS Location must be considered when assessing the relationship between PPP and plantar ulceration.

Measurement of functional heel pad behaviour in-shoe during gait using orthotic embedded ultrasonography. Gait Posture 2013; 39:328-32. [PMID: 23962596 DOI: 10.1016/j.gaitpost.2013.07.118] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2013] [Revised: 07/24/2013] [Accepted: 07/28/2013] [Indexed: 02/02/2023]
Abstract
The ability to measure the functional behaviour of the plantar heel pad is clinically relevant in dystrophic or pathological heel conditions and may help to inform the design and development of interventions that attempt to restore normal function. In this study we present a novel technique which utilises orthotic heel inserts with an embedded ultrasound (US) transducer to allow the functional, dynamic behaviour of the heel pad to be measured in-shoe during gait. The aim of this study was to demonstrate feasibility of the technique, determine the reproducibility of measurements, and to compare the effects of two orthotic inserts: (i) a flat orthotic heel raise and (ii) a contoured heel cup insert on the behaviour of the heel pad during gait. Dynamic compression of the heel pads of 16 healthy participants was recorded during treadmill walking and combined with plantar pressure measurements to allow stiffness and energy disappation ratio (EDR) to be estimated. Inter-session reliability of the US measurements was found to be excellent (ICC2,1=0.94-0.95), as was inter-rater reliability (ICC2,1=0.89). Use of the heel cup insert significantly reduced the maximum compression of the heel pad (p<0.0001) as well as the overall stiffness of the pad (p<0.001). There was no change in EDR (p=0.949). In-shoe embedded US is a reliable method to establish person-specific functional geometry of plantar soft tissues. Use of a contoured heel cup reduces the compression of the mid portion of the heel pad.

A case of heel reconstruction with a reverse sural artery flap in a hemophilia B patient. Arch Plast Surg 2012; 39:150-3.

Abstract
Hemophilia B is a rare blood coagulation disorder. Complications such as bleeding and hematoma can cause necrosis of flaps, wound disruption, and the disturbance of wound healing. In particular, guidelines for flap operations in hemophilia B patients have still not been defined, and case reports are rare. We reconstructed the heel of a 41-year-old male hemophilia B patient using a reverse sural artery flap operation. The patient presented with mild hemophilia, having 27% of the normal value of coagulation factor IX. Coagulation and the changing value of the coagulation factor were regularly measured, and 70% of the normal value of coagulation factor IX was maintained through the injection of recombinant coagulation factors and antihemorrhagics. Hematoma developed twice (postoperative day [POD] 5 and POD 7) and in each case the hematoma was removed. Injections of recombinant coagulation factors and antihemorrhagics were continuously administered until postoperative week 2. When the coagulation factors were within normal ranges. In this article, a hemophilia B patient underwent reverse sural artery flap surgery and the healing progress was analyzed. We conclude that higher than baseline levels of coagulation factors are needed for successful healing in reverse sural artery flap surgery.
