Fulltext Reconstruction of the heel defect with in-step island flap. A report of four cases

Kwan MK, Marican AM, Ahmad TS

Med J Malaysia, 2005 Jul;60 Suppl C:104-7.
PMID: 16381293

Soft tissue loss of the heel is difficult to treat as it may cause significant morbidity particularly recurrent ulceration and subsequent chronic osteomyelitis. Reconstruction of such defect with local flap can provide good result. We report our experience in treating four patients with heel defect using the in-step island flap. The flap, which is based on the medial plantar neurovascular pedicle, provides a sensate durable tissue required for weight-bearing and normal gait.

Fulltext Bone Mineral Density Assessment in Pre- and Postmenopausal Women: Comparison Between T-Scores by Heel QUS and DXA in HRPZII

Zaini WM, Md Ariff A

Med J Malaysia, 2012 Oct;67(5):487-90.
PMID: 23770864 MyJurnal

This short-term study which was carried out in a small group of pre- and postmenopausal women at Hospital Raja Perempuan Zainab II (HRPZII) aims to compare between Tscores detected by heel Quantitative Ultrasound (QUS) and by Dual X-ray Absorptiometry (DXA) of the hip and spine. The prevalence of osteoporosis by heel QUS was 63.3% and up to 16.7% by DXA. Insufficient or weak agreement exists between T-score measurements by heel QUS and axial DXA. Significant correlations were found between measurements of T-scores by both methods, with r values from 0.364 to 0.91. Although some correlation was found, significant discrepancy in the frequency of osteoporosis using different methods and sites is substantial.

Fulltext Principal Component Analysis of the Running Ground Reaction Forces With Different Speeds

Yu L, Mei Q, Xiang L, Liu W, Mohamad NI, István B, et al.

Front Bioeng Biotechnol, 2021;9:629809.
PMID: 33842444 DOI: 10.3389/fbioe.2021.629809

Ground reaction force (GRF) is a key metric in biomechanical research, including parameters of loading rate (LR), first impact peak, second impact peak, and transient between first and second impact peaks in heel strike runners. The GRFs vary over time during stance. This study was aimed to investigate the variances of GRFs in rearfoot striking runners across incremental speeds. Thirty female and male runners joined the running tests on the instrumented treadmill with speeds of 2.7, 3.0, 3.3, and 3.7 m/s. The discrete parameters of vertical average loading rate in the current study are consistent with the literature findings. The principal component analysis was modeled to investigate the main variances (95%) in the GRFs over stance. The females varied in the magnitude of braking and propulsive forces (PC1, 84.93%), whereas the male runners varied in the timing of propulsion (PC1, 53.38%). The female runners dominantly varied in the transient between the first and second peaks of vertical GRF (PC1, 36.52%) and LR (PC2, 33.76%), whereas the males variated in the LR and second peak of vertical GRF (PC1, 78.69%). Knowledge reported in the current study suggested the difference of the magnitude and patterns of GRF between male and female runners across different speeds. These findings may have implications for the prevention of sex-specific running-related injuries and could be integrated with wearable signals for the in-field prediction and estimation of impact loadings and GRFs.

Effects of Running Surface Stiffness on Three-Segment Foot Kinematics Responses with Different Shod Conditions

Abdul Yamin NAA, Basaruddin KS, Salleh AF, Salim MS, Wan Muhamad WZA

Appl Bionics Biomech, 2021;2021:8842591.
PMID: 33603827 DOI: 10.1155/2021/8842591

Objective: The aim of this study was to investigate the effects of surface stiffness on multisegment foot kinematics and temporal parameters during running.
Methods: Eighteen male subjects ran on three different surfaces (i.e., concrete, artificial grass, and rubber) in both heeled running shoes (HS) and minimal running shoes (MS). Both these shoes had dissimilar sole profiles. The heeled shoes had a higher sole at the heel, a thick base, and arch support, whereas the minimal shoes had a flat base sole. Indeed, the studied biomechanical parameters responded differently in the different footwear during running. Subjects ran in recreational mode speed while 3D foot kinematics (i.e., joint rotation and peak medial longitudinal arch (MLA) angle) were determined using a motion capture system (Qualysis, Gothenburg, Sweden). Information on stance time and plantar fascia strain (PFS) was also collected.
Results: Running on different surface stiffness was found to significantly affect the peak MLA angles and stance times for both HS and MS conditions. However, the results showed that the joint rotation angles were not sensitive to surface stiffness. Also, PFS showed no relationship with surface stiffness, as the results were varied as the surface stiffness was changed.
Conclusion: The surface stiffness significantly contributed towards the effects of peak MLA angle and stance time. These findings may enhance the understanding of biomechanical responses on various running surfaces stiffness in different shoe conditions.

Medial plantar artery (instep flap) flap

Mourougayan V

Ann Plast Surg, 2006 Feb;56(2):160-3.
PMID: 16432324

Provision of sensation to the weightbearing surface of the heel is very vital in the sensate foot. Hence, resurfacing the weightbearing surface of the heel requires provision of stable skin cover and sensation. We have many options to fulfill the above requirements. Skin of the instep area can be raised as an island fasciocutaneous flap based on medial plantar vessels, with the branch of medial plantar nerve supplying the instep skin to provide the sensation. Medial plantar artery (instep) flap provides similar tissue with sensation and reaches the posteriormost part of the weightbearing surface of the heel with ease. We present in this article the relevant surgical anatomy, technique, and the clinical experience of 12 patients.

Khai Luen K, Wan Sulaiman WA

J Foot Ankle Surg, 2017 8 27;56(5):1114-1120.
PMID: 28842095 DOI: 10.1053/j.jfas.2017.04.024

Sensate, durable heel pad reconstruction is challenging. The present study assessed the functional outcomes after heel pad reconstruction using various flap techniques at our institution. From June 2011 to June 2016 (5-year period), 7 consecutive patients underwent heel pad reconstruction for various etiologies, with 3 microvascular free flaps (42.9%; 2 musculocutaneous flaps [66.7%] and 1 contralateral medial plantar flap [33.3%]) and 4 local pedicle flaps (57.1%; 3 instep medial plantar artery flaps [75.0%] and 1 distally based reverse sural flap [25.0%]). The patient records and demographic data were reviewed, and surgically related information was obtained and analyzed. The subjective components of the American Orthopaedic Foot and Ankle Society hindfoot clinical ratings scale were used to evaluate the pain and functional outcomes. Sensation was assessed using Semmes-Weinstein monofilaments, and ulcer recurrence was recorded. The mean age of the patients was 41.7 (range 11 to 70) years, the mean defect size was 59 (range 12 to 270) cm2, and the mean follow-up duration was 22 (range 15 to 43) months. Complete flap survival was achieved without significant complications in all 7 patients. Patients treated with the sensate medial plantar artery flap recorded the highest mean American Orthopaedic Foot and Ankle Society score of 57.3 (maximum score of 60) and experienced a return of deep sensation at 6 (range 6 to 24) months and protective sensation at 1 year. This was followed by the reverse sural flap and the musculocutaneous flap. No recurrent heel ulceration was observed in our series of patients. In conclusion, the sensate medial plantar flap is a satisfactory method for coverage of small- to moderate-size heel defects.

Heel Pad Reconstruction With Medial Plantar Flap

Langat AS, Wan Sulaiman WA, Mat Johar SFN

Cureus, 2021 Mar 19;13(3):e13987.
PMID: 33884238 DOI: 10.7759/cureus.13987

The heel of the foot is covered by highly specialized thick, glabrous skin containing fibroadipose tissue with numerous fibrous septae traversing the subcutaneous tissue, which acts as a shock-absorbent and prevents shearing of the skin. The loss of heel pad would cause interruption of the propelling function of the foot during walking. Therefore, heel pad reconstruction is an important procedure for wound closure in the acute phase and also functional reconstruction in delayed cases. We report a case of heel pad deformity in a patient who presented to us with left heel pain and inability to fully bear weight, which has caused her walking difficulty, following a road traffic accident. She sustained a degloving injury of the left foot and an open fracture of left calcaneum with ruptured Tendon Achilles in which the wound was initially addressed with failed reverse sural flap and the wound was allowed to heal by secondary intention. Delayed heel reconstruction was carried out with a propeller medial plantar flap and split skin graft. Postoperatively, the patient had improved functional and esthetic outcome.

Borneo Journal of Medical Sciences, 2019;13(3):65-70.
MyJurnal

Osteochondromyxoma is a rare bone tumour. Bone tumours of the talus are also uncommon, and accounts to be between 8% to 23% in tumours of the foot. A 28-year-old man presented with chronic right ankle pain. He had underlying left knee ligament and meniscal injury. Special examination tests for ligament injury were negative. Magnetic Resonance Imaging (MRI) revealed a benign bone lesion of talus with reactive oedema of sinus tarsi. Excision of lesion was done and subsequent histopathological examination confirmed the diagnosis of ostechondromyxoma.

MyJurnal

We report a case of 29-year-old female who presented with right heel pain that worsened over a period of two years. The onset of pain was followed by swelling at the medial aspect of right ankle. She was initially treated for plantar fasciitis with multiple steroid injections over the heel. Subsequent MRI revealed a well-defined heterogeneous lesion in continuity with the medial plantar nerve. Excision biopsy was performed and histopathological evaluation revealed monophasic synovial sarcoma. The patient subsequently underwent wide resection and free tissue transfer followed by radiotherapy and chemotherapy. This case highlights an unusual site and presentation of synovial sarcoma which led to delayed diagnosis and treatment.

Fulltext Chronic heel pain: It could be tuberculosis

Muhamad Effendi F, Ibrahim MI, Rozali KN, Miswan MF

Malays Fam Physician, 2016;11(2-3):20-23.
PMID: 28461854 MyJurnal

INTRODUCTION: Heel pain is a common presentation at a primary care setting. The majority of these cases are benign and self limiting in nature. Common differential diagnoses include plantar fasciitis and peroneal muscle sprains. However, certain conditions-if undetected early-may cause significant morbidity to the patient. A high index of suspicion and early referral for further investigations are needed to prevent long-term morbidities.

METHODS: A clinical review of a patient with chronic left heel pain was performed. Blood parameters and imaging investigations indicated chronic infection of the calcaneum. Histopathological examination was highly suggestive of tuberculosis.

RESULT: The patient responded well to antituberculous therapy. She was pain free and showed no signs of recurrence at final follow-up.

CONCLUSION: Here, we report a case of chronic heel pain, which was later diagnosed as tuberculosis of the calcaneum and successfully treated with antituberculous therapy.

Fulltext Does Vertical Ground Reaction Force of the Hip, Knee, and Ankle Joints Change in Patients with Adolescent Idiopathic Scoliosis after Spinal Fusion?

Yusof MI, Shaharudin S, Sivalingarajah P

Asian Spine J, 2018 Apr;12(2):349-355.
PMID: 29713418 DOI: 10.4184/asj.2018.12.2.349

Study Design: Comparative cross-sectional study.
Purpose: We measured the vertical ground reaction force (vGRF) of the hip, knee, and ankle joints during normal gait in normal patients, adolescent idiopathic scoliosis (AIS) patients with a Cobb angle <40° and in AIS patients with spinal fusion. We aimed to investigate whether vGRF in the aforementioned joints is altered in these three groups of patients.
Overview of Literature: vGRF of the lower limb joints may be altered in these groups of patients. Although it is known that excessive force in the joints may induce early arthritis, there is limited relevant information in the literatures.
Methods: We measured vGRF of the hip, knee, and ankle joints during heel strike, early stance, mid stance, and toe-off phases in normal subjects (group 1, n=14), AIS patients with Cobb angle <40° (group 2, n=14), and AIS patients with spinal fusion (group 3, n=13) using a gait analysis platform. Fifteen auto-reflective tracking markers were attached to standard anatomical landmarks in both the lower limbs. The captured motion images were used to define the orientations of the body segments and force exerted on the force plate using computer software. Statistical analysis was performed using independent t-test and analysis of variance to examine differences between the right and left sides as well as those among the different subject groups.
Results: The measurements during the four gait phases in all the groups did not show any significant difference (p>0.05). In addition, no significant difference was found in the vGRF measurements of all the joints among the three groups (p>0.05).
Conclusions: A Cobb angle <40° and spinal fusion did not significantly create imbalance or alter vGRF of the lower limb joints in AIS patients.

Amelanotic spitzoid melanoma in a prepubescent boy

Goh EH, Zarina AL, Thambidorai CR, Maizaton AA, Siti AM, Somasundram S

Pediatr Surg Int, 2008 Apr;24(4):447-9.
PMID: 17437116

The diagnosis of malignant melanoma (MM) in children is difficult due to its uncommon occurrence as well histological similarities to Spitz nevus. A case of MM of the foot in an 11-year-old boy is reported illustrating the histological overlap between Spitz nevus and MM. In our patient, both the primary foot lesion and the regional inguinal metastases were amelanotic, further increasing the diagnostic difficulty. The literature on MM in children is limited and the documentation of such unusual cases is necessary to improve the knowledge on this disease.

Fulltext F-FDG PET/CT as a potential valuable adjunct to MRI in characterising the Brodie's abscess

Fathinul F, Nordin A

Biomed Imaging Interv J, 2010 07 01;6(3):e26.
PMID: 21611044 DOI: 10.2349/biij.6.3.e26

Chronic osteomyelitis (Brodie's abscess) is essentially a problem of diagnosis, and there may be considerable difficulty in distinguishing it from other benign and malignant bone lesions. Early diagnosis of Brodie's abscess is deemed important as the disease has a good curative potential following an appropriate antibiotic treatment. Of late, PET/CT using (18)F-FDG is taking a centre stage in the imaging of bone infection though documentation on its role in characterising the feature of Brodie's abscess is exceedingly scarce. On the other hand, it is well known that MRI imaging plays a very important role in distinguishing abscess loculation from malignancy. The authors present the case of a 13-year-old boy with pain in the right heel for few months. Radiograph of the right foot revealed a lucent focus with sclerotic margin in the right calcaneum. MRI T1-weighted images were inconclusive of penumbra sign to characterise abscess cavity due to the small volume lesion. Whole-body (18)F-FDG PET/CT scan showed multiple small avid lesions at the margin of the sclerotic rim in the right calcaneum. Final diagnosis of Brodie's abscess with Klebsiella culture was confirmed via bone debridement.

Fulltext Medico-legal implications of dental prenatal age estimation with reference to a case report

Nambiar, P., Paul, G., Swaminathan, D., Nadesan, K.

Ann Dent, 2000;7(1):46-50.
MyJurnal

The estimation of age of human foetal remains is of great medico-legal importance. When the remains are intact and fresh, various morphological features such as crown-heel length, weight, appearance of ossification centres particularly around the ankles and knees and other parameters could be used to make a reasonable estimation of the period of gestation. In cases of criminal abortion, infanticide and child murder the question of age of the foetus, viability, live birth and a separate existence become very important. In practice, often at the time of detection, the remains are decomposed or skeletonised. In such a situation the examination of developing teeth will provide a reliable answer pertaining to the foetal age, the possibility of a separate existence and even the period of survival after birth. The.age determination from dental examination is possible from approximately 10 weeks intrauterine up to old age. The presence of neonatal line (birth line) in both dentine and enamel indicates live birth and a separate existence. It is possible that the time period of survival can be estimated by measuring postnatal deposition of these hard tissues. An intact human foetus that has undergone mild to moderate putrefaction was studied. The study of the morphological features and the ossification centres suggested that its approximate age was around nine months intrauterine. It was not possible to decide whether it was a live birth and had a separate existence. The examination of the developing first deciduous molar of the mandible suggested the approximate age was around 30-32 weeks intrauterine. The importance of examination of developing teeth in foetal remains (including neonates), particularly associated with putrefaction or skeletonisation is emphasized.

Unexpected sequelae of plantar fasciitis: Iatrogenic calcaneal osteomyelitis following plantar heel injection

Mohd Khalid SA, Bajuri MY

Malays Fam Physician, 2019;14(3):80-83.
PMID: 32175048

The injection of a local anesthetic in combination with a corticosteroid is an accepted choice in the treatment of plantar fasciitis with recalcitrant heel pain. When the injection is performed properly, post-injection infection is extremely rare. We are reporting a rare case of chronic calcaneal osteomyelitis that developed secondary to a local corticosteroid injection. A 56-year-old lady diagnosed with right plantar fasciitis presented with a 6-month history of pain and a persistent sinus with serous discharge of her right heel following a local infiltration of a corticosteroid. A Magnetic Resonance Imaging demonstrated right calcaneal osteomyelitis with intramuscular abscess. Surgical drainage and debridement were done, followed by antibiotic therapy. A recurrence of infection was not detected throughout the duration of follow-up. It is suggested that a plantar heel injection be done in a more controlled environment, such as in operating theatre, to reduce the risk of infection and to avoid injecting a steroid as compared to platelet-rich plasma (PRP) in view of their safety profiles. However, such an injection should only be offered after conservative treatment has failed, as 80% of patients recover well after initial conservative management.

Fulltext Is Platelet-rich Plasma Injection more Effective than Steroid Injection in the Treatment of Chronic Plantar Fasciitis in Achieving Long-term Relief?

Soraganvi P, Nagakiran KV, Raghavendra-Raju RP, Anilkumar D, Wooly S, Basti BD, et al.

Malays Orthop J, 2019 Nov;13(3):8-14.
PMID: 31890104 DOI: 10.5704/MOJ.1911.002

Introduction: Plantar fasciitis is characterised by pain in the heel, which is aggravated on weight bearing after prolonged rest. Many modalities of treatment are commonly used in the management of plantar fasciitis including steroid injection. Many studies show that steroid injection provides pain relief in the short term but not long lasting. Recent reports show autologous platelet-rich plasma (PRP) injection promotes healing, resulting in better pain relief in the short as well as long term. The present study was undertaken to compare the effects of local injection of platelet-rich plasma and Corticosteroid in the treatment of chronic plantar fasciitis. Materials and methods: Patients with the clinical diagnosis of chronic plantar fasciitis (heel pain of more than six weeks) after failed conservative treatment and plantar fascia thickness more than 4mm were included in the study. Patients with previous surgery for plantar fasciitis, active bilateral plantar fasciitis, vascular insufficiency or neuropathy related to heel pain, hypothyroidism and diabetes mellitus were excluded from the study. In this prospective double-blind study, 60 patients who fulfilled the criteria were divided randomly into two groups. Patients in Group A received PRP injection and those in Group B received steroid injection. Patients were assessed with visual analog scale (VAS) and American Orthopedic Foot and Ankle Society (AOFAS) score. Assessment was done before injection, at six weeks, three months and six months follow-up after injection. Plantar fascia thickness was assessed before the intervention and six months after treatment using sonography. Results: Mean VAS in Group A decreased from 7.14 before injection to 1.41 after injection and in Group B decreased from 7.21 before injection to 1.93 after injection, at final follow-up. Mean AOFAS score in Group A improved from 54 to 90.03 and in Group B from 55.63 to 74.67 at six months' follow-up. The improvements observed in VAS and AOFAS were statistically significant. At the end of six months' follow-up, plantar fascia thickness had reduced in both groups (5.78mm to 3.35mm in Group A and 5.6 to 3.75 in Group B) and the difference was statistically significant. Conclusion: Local injection of platelet-rich plasma is an effective treatment option for chronic plantar fasciitis when compared with steroid injection with long lasting beneficial effect.
