The aim of this study was to compare the longer-term outcomes of operatively and nonoperatively managed patients treated with a removable brace (fixed-angle removable orthosis) or a plaster cast immobilization for an acute ankle fracture. This is a secondary analysis of a multicentre randomized controlled trial comparing adults with an acute ankle fracture, initially managed either by operative or nonoperative care. Patients were randomly allocated to receive either a cast immobilization or a fixed-angle removable orthosis (removable brace). Data were collected on baseline characteristics, ankle function, quality of life, and complications. The Olerud-Molander Ankle Score (OMAS) was the primary outcome which was used to measure the participant’s ankle function. The primary endpoint was at 16 weeks, with longer-term follow-up at 24 weeks and two years.Aims
Methods
In the context of tendon degenerative disorders, the need for innovative conservative treatments that can improve the intrinsic healing potential of tendon tissue is progressively increasing. In this study, the role of pulsed electromagnetic fields (PEMFs) in improving the tendon healing process was evaluated in a rat model of collagenase-induced Achilles tendinopathy. A total of 68 Sprague Dawley rats received a single injection of type I collagenase in Achilles tendons to induce the tendinopathy and then were daily exposed to PEMFs (1.5 mT and 75 Hz) for up to 14 days - starting 1, 7, or 15 days after the injection - to identify the best treatment option with respect to the phase of the disease. Then, 7 and 14 days of PEMF exposure were compared to identify the most effective protocol.Aims
Methods
There is little information about how to manage patients with a recurvatum deformity of the distal tibia and osteoarthritis (OA) of the ankle. The aim of this study was to evaluate the functional and radiological outcome of addressing this deformity using a flexion osteotomy and to assess the progression of OA after this procedure. A total of 39 patients (12 women, 27 men; mean age 47 years (28 to 72)) with a distal tibial recurvatum deformity were treated with a flexion osteotomy, between 2010 and 2015. Nine patients (23%) subsequently required conversion to either a total ankle arthroplasty (seven) or an arthrodesis (two) after a mean of 21 months (9 to 36). A total of 30 patients (77%), with a mean follow-up of 30 months (24 to 76), remained for further evaluation. Functional outcome, sagittal ankle joint OA using a modified Kellgren and Lawrence Score, tibial lateral surface (TLS) angle, and talar offset ratio (TOR) were evaluated on pre- and postoperative weight-bearing radiographs.Aims
Patients and Methods
Injuries to the foot in athletes are often subtle
and can lead to a substantial loss of function if not diagnosed
and treated appropriately. For these injuries in general, even after
a diagnosis is made, treatment options are controversial and become
even more so in high level athletes where limiting the time away
from training and competition is a significant consideration. In this review, we cover some of the common and important sporting
injuries affecting the foot including updates on their management
and outcomes. Cite this article:
Achieving arthrodesis of the ankle can be difficult
in the presence of infection, deformity, poor soft tissues and bone loss.
We present a series of 48 patients with complex ankle pathology,
treated with the Ilizarov technique. Infection was present in 30
patients and 30 had significant deformity before surgery. Outcome
was assessed clinically and with patient-reported outcome measures
(Modified American Orthopaedic Foot and Ankle Society (MAOFAS) scale and
the Short-Form (SF-36)). Arthrodesis was achieved in 40 patients with the Ilizarov technique
alone and in six further patients with additional surgery. Infection
was eradicated in all patients at a mean follow-up of 46.6 months
(13 to 162). Successful arthrodesis was less likely in those with
comorbidities and in tibiocalcaneal fusion compared with tibiotalar
fusion. These patients had poor general health scores compared with the
normal population before surgery. The mean MAOFAS score improved
significantly from 24.3 (0 to 90) pre-operatively to 56.2 (30 to
90) post-operatively, but there was only a modest improvement in
general health; the mean SF-36 improved from 44.8 (19 to 66) to
50.1 (21 to 76). There was a major benefit in terms of pain relief. Arthrodesis using the Ilizarov technique is an effective treatment
for complex ankle pathology, with good clinical outcomes and eradication
of infection. However, even after successful arthrodesis general
health scores remain limited. Cite this article:
We present the results of ankle fusion using the Ilizarov technique for bone loss around the ankle in 20 patients. All except one had sustained post-traumatic bone loss. Infection was present in 17. The mean age was 33.1 years (7 to 71). The mean size of the defect was 3.98 cm (1.5 to 12) and associated limb shortening before the index procedure varied from 1 cm to 5 cm. The mean time in the external fixator was 335 days (42 to 870). Tibiotalar fusion was performed in 19 patients and tibiocalcaneal fusion in one. Associated problems included diabetes in one patient, pelvic and urethral injury in one, visual injury in one patient and ipsilateral tibial fracture in five. At the final mean follow-up of 51.55 months (24 to 121) fusion had been achieved in 19 of 20 patients. A total of 16 patients were able to return to work. The results were graded as good in 11 patients, fair in six and poor in three. The mean external fixation index was 8.8 days/mm (0 to 30). One patient with diabetes developed severe infection which required early removal of the fixator. Refractures occurred in three patients, two of which were at the site of fusion and one at a previous tibial shaft fracture site. Equinus deformity of the ankle fusion occurred after a further fracture in one patient. There were two patients with residual forefoot equinus, and one developed late valgus at the fusion site. Poor consolidation of the regenerated bone in two patients was treated by bone grafting in one and by bone and fibular strut grafting in the other. Residual soft-tissue infection was still present in two patients.
