Diagnosis and conservative management of great toe pathologies: a review

The development of recommendations for the assessment and management of sesamoiditis by podiatrists: A Delphi and content validity study

INTRODUCTION

Sesamoiditis is a common, and often painful, musculoskeletal pathology frequently encountered by podiatrists. However, there are currently no recommendations to guide podiatrists in the assessment and management of people with sesamoiditis. The aim of this study was to develop consensus-driven clinical recommendations on the assessment and management of people with sesamoiditis.

METHODS

A four-round online Delphi survey was conducted with a panel of New Zealand and Australian podiatrists. In the first round, panellists answered open-ended questions that were used to create statements. In round two, the panellists scored the statements from 1 to 9 (1 = not at all important, 9 = absolutely essential). Consensus was defined using the RAND/University of California Los Angles Disagreement Index. Panellists were asked to reconsider statements that did not achieve consensus in round three. In the final round, content validity and acceptability of the statements for inclusion in clinical recommendations were determined using content validity ratios and the Content Validity Index (CVI).

RESULTS

Eighteen panellists completed round one with 16 (89%) completing all four rounds. A total of 118 statements were generated following round one. Following rounds two and three, 78 statements were accepted by panellists as being important, with 62 statements achieving sufficient content validity for inclusion in clinical recommendations. The CVI for these 62 statements was 0.58. These recommendations provide guidance on subjective assessment (pain characteristics/symptomology, activity/sports/training history and medical history) objective assessment (establishing a diagnosis, identifying contributing biomechanical factors, footwear/orthoses, ruling out differential diagnoses) and management (temporary padding/strapping, education, footwear, foot orthoses and when to consider referral).

CONCLUSION

This consensus exercise has provided a set of consensus-based recommendations for the assessment and management of people with sesamoiditis. In the current absence of research-based evidence in this area, these recommendations are intended to support clinicians. The recommendations may also serve as a basis for future clinical trials evaluating the efficacy of conservative interventions for people with sesamoiditis.

Foot pain in children and adolescents: a problem-based approach in musculoskeletal ultrasonography

Various etiologies and risk factors contribute to foot pain in children and adolescents, including conditions such as Kohler's disease, Sever's disease, Iselin's disease, rigid flat foot, accessory navicular, Freiberg's disease, sesamoiditis, os trigonum syndrome, and more. High-frequency musculoskeletal ultrasonography can show both the bone surface and the surrounding soft tissue clearly from various angles in real-time, thereby providing a higher level of detail that is helpful for identifying the etiology of foot pain and monitoring disease progression compared with other imaging modalities. This review provides an overview of the epidemiology, pathophysiology, clinical manifestations and characteristic ultrasonographic findings of select foot pain conditions in children and adolescents.

Paediatric sand toe: radiographic, ultrasound and MRI findings of dorsomedial capsular injury

Hyperflexion injury to the metatarsophalangeal joint of the great toe, referred to as sand toe, can cause significant functional impairment. To our knowledge, there have been no radiological descriptions of this injury in the paediatric age group. Here, we report radiographic, sonographic and MRI findings in a male paediatric patient who sustained a sand toe injury, highlighting structural damage to the dorsomedial capsule and medial sagittal band, and discuss sand toe's favourable prognosis with conservative management.

Hallucal sesamoiditis on a bipartite sesamoid bone: An uncommon cause of chronic great toe pain

The pathologies and lesions affecting the sesamoid bones of the hallux are uncommon and can be easily overlooked. Among them, sesamoiditis is a relatively rare condition known to cause severe great toe pain; lack of awareness of this particular entity leads to misdiagnosis, delayed treatment, and contributes to significant morbidity. Herein, we present a chronic sesamoiditis case occurring on a medial bipartite sesamoid bone, presenting as chronic great toe pain. The main purpose of this work is to discuss the role of magnetic resonance imaging and X-rays in the diagnosis process. To the best of our knowledge, no cases of great toe sesamoiditis occurring on a bipartite bone in no-athletic patients have yet been reported.

Severe hallux valgus can be treated using a distal metatarsal osteotomy: Results of 144 cases treated with the SERI technique

PURPOSE

Aim of this study is to analyze the clinical and radiographic results of the simple, effective, rapid and inexpensive (SERI) technique, a linear distal metatarsal osteotomy, for treating severe hallux valgus (HV).

METHODS

Clinical outcomes were assessed pre- and postoperatively using the AOFAS, MOxFQ and VAS score. Pre and postoperative HV angle (HVA) and intermetatarsal angle (IMA) were measured.

RESULTS

117 consecutive patients for a total of 144 feet were included. Pre and postoperatively, mean AOFAS changed from 44.8 ± 16.7 to 89 ± 10.3 (p < .001), mean MOxFQ changed from 76.2 ± 15.8 to 23.4 ± 7.9 (p < .001) and mean VAS score improved from 6.7 ± 2.1 to 1.5 ± 1.5 (p < .001). HVA diminished from 40.6° ± 6.9 preoperatively to 16.0° ± 7.3 postoperatively (p < .001). IMA decreased from 15.1° ± 2.8 preoperatively to 6.5° ± 2.4 postoperatively (p < .001). The main complication reported was stiffness (10.4 %).

CONCLUSION

SERI technique applied to severe HV showed positive clinical and radiological outcomes. A careful patient selection and a low grade first MTPJ arthritis are essential to obtain favorable results.

First Metatarsophalangeal Joint Pain in Athletes: Diagnosis, Management, and Return to Play Considerations

ABSTRACT

The first metatarsal-phalangeal joint plays a key role for athletes of various disciplines. When an athlete presents for evaluation of pain at this joint, there are several causes that should be considered. The purpose of this article is to review common injuries including turf toe, sand toe, extensor and flexor hallucis longus tendinopathy, sesamoiditis, and metatarsalgia and provide current evidence-based recommendations for diagnosis, management, and return to play considerations. Conditions not specific to athletes like gout and hallux rigidus also are discussed. Mechanism of injury, physical examination, and imaging such as weight-bearing radiographs and point-of-care ultrasound can help with diagnosis. Treatment of many of these injuries begins with nonsurgical management strategies including footwear or activity modification, physical therapy, and select interventions.

The assessment and management of sesamoiditis: a focus group study of podiatrists in Aotearoa New Zealand

BACKGROUND

Sesamoiditis is a common inflammatory condition affecting the sesamoid bones at the plantar aspect of the first metatarsophalangeal joint (1MTPJ). However, there are currently no recommendations or clinical guidelines to support podiatrists in their assessment or management of sesamoiditis. The aim of this study was to explore the views of podiatrists in Aotearoa New Zealand on their approaches to the assessment and management of patients with sesamoiditis.

METHODS

This qualitative study included focus group discussions with registered podiatrists. Focus groups took place online via Zoom and were guided by a detailed focus group question schedule. The questions were designed to encourage discussion around assessment approaches used in the diagnosis of sesamoiditis and the treatment tools used to manage patients with sesamoiditis. Focus groups were audio-recorded and transcribed verbatim. Reflexive thematic analysis was used to analyse the data.

RESULTS

A total of 12 registered podiatrists participated in one of three focus groups. Four themes were constructed relating to the assessment of sesamoiditis: (1) obtaining a patient history; (2) recreating patient symptoms; (3) determining contributing biomechanical factors; and (4) ruling out differential diagnoses. Seven themes were constructed relating to the management of sesamoiditis: (1) consideration of patient factors; (2) patient education; (3) cushioning of the sesamoids to allow more comfortable weightbearing of the 1MTPJ; (4) pressure redistribution and offloading of the sesamoids; (5) immobilisation of the 1MTPJ and sesamoids; (6) facilitating efficient sagittal plane motion during gait; (7) referring to other health professionals to find different ways to treat or manage patient symptoms.

CONCLUSION

Podiatrists in Aotearoa New Zealand demonstrate an analytical approach in the assessment and management of patients with sesamoiditis based on their clinical experience and knowledge of lower limb anatomy. A range of assessment and management techniques are selected based on the practitioners personal preferences, as well as the patient's social factors, symptomology, and lower limb biomechanics.

Congenital Malalignment of the Great Toenail, the Disappearing Nail Bed, and Distal Phalanx Deviation: A Review

<b><i>Importance:</i></b> Congenital malalignment of the great toenail (CMGT) is an idiopathic deviation of the nail apparatus. CMGT predisposes patients to recurrent stress forces, microtrauma, and secondary complications. The purpose of this study was to review the current published photographs to determine the relationship between variants of CMGT and the disappearing nail bed (DNB). <b><i>Observations:</i></b> A search in PubMed and Google using the terms congenital malalignment of the great toenail, disappearing nail bed, and lateral nail deviation was performed. Of the 53 photographs found in a total of 35 articles, 23 were disqualified due to low picture resolution or poor angle. The remaining 30 photographs were evaluated. Pure nail malalignment with associated dystrophy and DNB was found in 22 of 30 photographs. Four of 30 cases demonstrated pure deviation of the distal phalanx, with nail dystrophy but minimal DNB. The remaining 4 cases demonstrated a combination of toe deviation and nail unit deviation with varying degrees of DNB. <b><i>Conclusions and Relevance:</i></b> DNB was associated with all forms of pure CMGT. Moreover, a variant of malalignment of the distal phalanx was noted in 8 photographs. This has potential implications for further studies and treatment to correct secondary complications.
