Described below is a case of catastrophic failure of a Moje press fit first MTP ceramic implant. The failure of the device was later discovered to have occurred due to damage occurring in the manufacturing process.
We report a rare case of a ganglion occurring in the big toe of an 8-year-old boy whose chief complaint was sensory change, especially while walking. On MR image, a 20mm × 15mm × 12mm sized multilobular tumor was visualized on the planter side of the right big toe. The tumor had low signal intensities on T1WI, and homogenously high signal intensities on T2WI. The tumor was removed with the tendon...
Information derived from footprint data serves as a useful, reliable and objective component to the assessment of patients with musculoskeletal pathology. Common spatial parameters extrapolated from such data include the angle and base of gait. Previous research has described a reliable method for analysing dynamic footprint data. While this data remains fundamental, few studies, if any have documented...
Patients with fixed equinus and associated angular and rotational deformities, who have had multiple previous surgeries, present a significant challenge to the orthopaedic surgeon. We chose to correct these deformities with supramalleolar extension wedge osteotomies in 21 feet in 13 patients between 1991 and 2002. The median age at presentation was 11 years (range: 2–17 years). An average correction...
In view of rarity of isolated talus tuberculosis a case is reported here. A 7-year-old boy referred us with 3 months history of swelling and pain of left ankle. On laboratory evaluation, he had an elevated ESR only. X-ray showed an extensive lytic lesion of talus. Chest radiograph was normal. The Mantoux skin test was negative. Histologic examination of biopsy tissue showed granulomatous and caseating...
We report an uncommon case of diastasis of the ankle without associated fracture. The injury was suspected on clinical examination and confirmed on plain radiographs. The patient refused to undergo surgery to stabilise the syndesmosis, and was therefore, treated conservatively in plaster cast for six weeks. The patient fully recovered from injury with good functional results. A high index of suspicion...
The clinical presentation of Morton's neuroma can be variable and investigations are often used for confirmation. Imaging modalities include ultrasound, CT and MR scanning. We report the sensitivity of MR for assessing Morton's neuroma.Twenty-one clinically suspected and histologically confirmed cases of Morton's neuroma were analysed retrospectively. All patients have had magnetic resonance scanning...
Ankle bracing is widely used by sports participants in order to prevent lateral ankle sprains. Current evidence on the various effects of ankle orthoses reveals that not only they are effective in minimizing the risk of injury, but also they do not hinder athletic performance and other parameters related to function. This review attempts to present all currently existing evidence regarding the effects...
Background: Gait analysis using footprint impressions is a simple and inexpensive method of obtaining valuable information relating to foot dynamics. Objectives: To assess the reliability and comparability of two different measurement techniques to quantify angle of gait (AOG). Method: Part 1. Two observers measured angle of gait (AOG), in six asymptomatic adult subjects, three times at weekly intervals...
A glomangioma is a rare benign tumor of a glomus body. We report the case of a large (6cm×4cm×4cm) painless glomangioma on the dorsum of a 52-year-old male's left foot. We believe this to be one of the largest reported.
Many children walk barefoot in South Africa. Unshod (barefoot) or partially shod (thong-type sandals) leisure behaviour may persist in adulthood. This study investigated whether unshod childhood results in adult increased forefoot width.Sixty urban adult females, of Afrikaans, English, Greek, Ndebele, Pedi, Sotho, Swati, Tswana, Venda, Xhosa and Zulu ethnic origin, constituted two groups of thirty...
Plantar dislocation of the first metatarsophalangeal joint is an extremely rare primary hyperflexion injury of forefoot with potential for more complex progression. Less severe injuries are common mainly in ballet dancers and to a lesser extent in footballers. We are proposing a new comprehensive biomechanical classification of the hallux metatarsophalangeal joint injuries by extending and modifying...
Foot pressures were measured in 10 healthy women, while walking in high-heeled (5.91±1.03cm) and low-heeled (1.95±1.06cm) shoes. The foot was divided into seven regions. For each region the following parameters were calculated: the peak pressure (PP), pressure time integral (PTI), maximum force (MF), force time integral (FTI), contact time (CT) and contact area (CA). In high heels loading was reduced...
The development of sarcoma in patients with Paget's disease of bone is a classic but rare event. We describe a patient presented with chronic right heel pain due to a pathological avulsion fracture of the posterosuperior corner of the Calcaneus secondary to sarcomatous change in monostotic Paget's disease. It is important to recognise the fact that an avulsion fracture in the Calcaneus can be caused...
We report the case of a closed degloving injury of the forefoot in a 33-year-old female motorcyclist. The injury was associated with vascular compromise of the lesser toes. Radiographic examination revealed the little toe soft tissue shadow to be empty of bones (the “empty toe sign”). Despite prompt open reduction of the toe bones into their soft tissue envelope, and measures to encourage distal perfusion,...
Footprints from force sensitive resistor (FSR) type pressure platforms have been shown to differ from ink prints, leading to a relative distortion of the arch index (AI).To compare the accuracy of the AI derived from a capacitance pressure platform relative to ink footprints.Area measurements (heel, midfoot, forefoot, hallux and lesser toes) were acquired simultaneously from ink footprints and a pressure...
