Articles and Clinical Information

shutterstock_241878727Intended audience: Healthcare professionals, students in all healthcare programmes and those who would desire as much information as possible.

Welcome to my clinical resource library which I hope will help people. Lectures can be arranged for GPs, Podiatry Branches as well as for lay groups. With an ever greater need for multidisciplinary work, information shared benefits all. As we say at Busypencilcase Communications – ‘Progress through the art of communication’.

Conflicting ideas about the human foot are considered for critical discussion.What are the knowns, and do they stand up to our modern perception of the foot condition? Published December 2016


The Chilled Foot

Written for local GPs around our hospital at Spire Little Aston, the information is designed to help patients combat general chilling of the foot. A DIY self help section is included together with tips . I recommend using the animal wool sock for acute chilling and chilblain. This is an old but inexpensive remedy. Published January 2015.

 Corns,Callus and Keratoma Study  for podiatrists

Definitions have been set out to compare work from 1984 and 2014. The outcome of has been reviewed as data from 165 podiatrists suggests that the understanding of the border and extent of the depth of each lesion from clinical photographs could account for variation in the results. This places the accuracy around 80%. The latest publication came out in November 2017 published in the Journal of Foot & Ankle Research.



The management of plantar corns and callus has a low cost-benefit with reduced prioritisation in healthcare. The distinction between types of keratin lesions that forms corns and callus has attracted limited interest. Observation is imperative to improving diagnostic predictions and a number of studies point to some confusion as to how best to achieve this. The use of photographic observation has been proposed to improve our understanding of intractable keratin lesions.


Students from a podiatry school reviewed photographs where plantar keratin lesions were divided into four nominal groups; light callus (Grade 1), heavy defined callus (Grade 2), concentric keratin plugs (Grade 3) and callus with deeper density changes under the forefoot (Grade 4). A group of ‘experts’ assigned from qualified podiatrists validated the observer rated responses by the students.


Cohen’s weighted statistic (k) was used to measure inter-observer reliability. First year students (unskilled) performed less well when viewing photographs (k = 0.33) compared to third year students (semi-skilled, k = 0.62). The experts performed better than students (k = 0.88) providing consistency with wound care models in other studies.


Improved clinical annotation of clinical features, supported by classification of keratin- based lesions, combined with patient outcome tools, could improve the scientific rationale to prioritise patient care. Problems associated with photographic assessment involves trying to differentiate similar lesions without the benefit of direct palpation. Direct observation of callus with and without debridement requires further investigation alongside the model proposed in this paper.

Callus classification-preparing new work based on an original study 30 years ago

David Tollafield reviews corns with clinical pictures in this information sheet based on his 1984/5 work. The original paper is published below as in 1985 in the Journal called The Chiropodist. Such lesions need to be carefully assessed by the professional as many skin excrescences are not suited to pedicure or repeated debridement. Diagnostic techniques are required together with wider professional specialisation to manage this form of foot pain. Research  carried out by the author during 2015-16 included 57 first and third year podiatry students matched against an expert panel. Reliability was analysed using Kappa statistics and considered more useful than percentage evaluation. For the first time the 1985 study could be objectively evaluated and the conclusion suggested that rather than 4 stages (types).

Heel pain is a repetitive stress condition causing foot pain. This presentation by David Tollafield to a West Midlands Podiatric Audience emphasised the fact that some conditions may not be simple.

All clinicians, including medical doctors should be aware that recalcitrant heel pain should be correctly diagnosed and a plan of treatment put into place rather than relying on repeat medications.

CLINICAL EVIDENCE: Hallux Valgus Surgery. February 2013

A Report from the PASCOM-10 Working Party written and developed by Anthony Maher FCPodS and David Tollafield FCPodS. The purpose of this and subsequent reports is to provide a summary of hallux valgus (bunion) treatment data held on the PASCOM-10 database at a national level. The PASCOM-10 online audit tool was introduced to the profession in May 2010 and represents a considerable leap forward in auditing the outcomes of podiatry treatment. PASCOM-10 replaced the previous software based system (PASCOM 2000). Since its introduction, PASCOM-10 has registered 31190 patients and 29446 episodes of care across 178 centres (system accessed at 16:00 on 24.01.2013). There are 429 registered users ranging from administrative staff to podiatrists of all grades. It is hoped that with time data generated by PASCOM-10 will become a useful tool for monitoring trends and for benchmarking services at a local level.

Complex Regional Pain Syndrome and foot surgery

This is a condition which is under reported and often misdiagnosed. Burning foot pain was once described by a sufferer as think of pain experienced when putting your hand in a bucket of scalding water without the ability to take it out. Such descriptions must bring home to clinicians and patient alike the potential for this condition to alter one’s way of life. The condition however is not always as severe but early diagnosis is critical. We aim for a diagnosis within three months if not faster but other conditions can mimick the potential symptoms and signs. This makes CRPS a tough condition to judge.

Can we sex up bunions? Short article for clinicians

The bunion (hallux valgus) is a misunderstood condition causing foot pain is often left too late to be managed effectively. Tollafield discusses why this is the case.

The effect of sedation with Midazolam on daycare foot surgery

Sedation has a profound effect on the quality of podiatric foot surgery and foot pain treatment. This work has taken four years to bring to the public although represents some 15 years of experience by leading podiatric surgeon David Tollafield. We all know blood pressure can be improved when we are anxious but this is the first podiatric study covering use of Midazolam with senior anaesthetist Dr Nike Akinwale. Articulo is a Spanish Podiatric Journal (English version).
