A retrospective analysis was done on 20 cases of interphalangeal joint fusion of the great toe utilizing longitudinal cortical screw fixation. The purpose of this study was to present a series of interphalangeal joint fusion great toe done in both paediatric and adult patients using 3.5mm cortical screws. Most of the patients had interphalangeal joint fusion along with Jones transfer and other associated procedures with a mean follow up period of 19 months. Arthrodesis was successfully achieved in all the patients. No one had pain at the interphalangeal joint of the great toe. A literature review on interphalangeal joint arthrodesis was done and advantages of cortical screw fixation over other techniques have also been presented.

Introduction

Osteochondritis dissecans (OCD) is a localised disorder of subchondral bone and the overlying articular cartilage. The most commonly used classification systems involve arthroscopy and MRI.

Aim

To investigate the correlation between arthroscopic and MR findings in patients with OCD of the talus.

Methods

16 ankles in 14 patients with radiographically proven OCD were reviewed. Nine were male and five female. Mean age was 35yrs (range 18–64yrs). The lesions were staged independently using the Guhl1 arthroscopic and Dipaola2 MR classification systems.

Results

Arthroscopically there were eight stable and eight unstable lesions. Of the eight stable lesions, MRI staged five as stable and three as unstable. Of the eight unstable lesions, MRI staged six as unstable and two as stable. This gives a sensitivity of diagnosing unstable lesions as 0.75, with a specificity of 0.63.

Conclusions

This small study demonstrates that MR scans may have some limitations in classifying OCD lesions of the talus. Possible explanations are discussed. We propose that MRI findings, of OCD of the talus, should not be taken in isolation, but correlated with the patients symptoms and signs to avoid unnecessary arthroscopy.

Hallux valgus deformity may cause overriding of the second toe. Hallux valgus correction surgery in the elderly can be debilitating and patients may suffer a long period of morbidity. We show the outcomes of amputation of over-riding second toe caused by gross hallux valgus in the elderly. Eight patients underwent amputation of their overriding second toe, one of these patients underwent bilateral second toe amputations. All surgery was performed as a day case. Six patients had surgery under a local anaesthetic, two patients had surgery under a general anaesthetic. Patients selected had asymptomatic or minimally symptomatic hallux valgus with an overriding second toe and did not want hallux valgus correction surgery. A disease specific questionnaire using a Visual Analogue Scale (VAS) was implemented measuring pain, discomfort, deformity and walking distance. Patients were followed up for a minimum nine of months.

Eight patients (nine feet) underwent amputation of their second toe. There were seven females and one male. The age range was 63–90 years (median 83 years). All patients had a painful second toe on wearing footwear. Skin ulceration occurred on the dorsum of second toe in two patients. The mean VAS for pain, deformity, discomfort and walking distance before and after surgery are:- (before/after); pain = (7.00/0.94), deformity = (7.44/2.78), discomfort = (7.78/1.22) and walking distance = (6.89/6.44). There were no cases of post-operative infection, wound dehiscence, bleeding or deep vein thrombosis. One patient complained of a painful neuroma after one year.

Amputation of the second toe significantly reduces pain, discomfort and the appearance of deformity (p< 0.01), there was no difference in the patient’s walking distance after surgery. We recommend this type of surgery as an alternative to hallux valgus correction surgery in the elderly if the first ray is not causing significant symptoms.
