Arthroscopic microfracture is a conventional form of treatment for patients with osteochondritis of the talus, involving an area of < 1.5 cm2. However, some patients have persistent pain and limitation of movement in the early postoperative period. No studies have investigated the combined treatment of microfracture and shortwave treatment in these patients. The aim of this prospective single-centre, randomized, double-blind, placebo-controlled trial was to compare the outcome in patients treated with arthroscopic microfracture combined with radial extracorporeal shockwave therapy (rESWT) and arthroscopic microfracture alone, in patients with ostechondritis of the talus. Patients were randomly enrolled into two groups. At three weeks postoperatively, the rESWT group was given shockwave treatment, once every other day, for five treatments. In the control group the head of the device which delivered the treatment had no energy output. The two groups were evaluated before surgery and at six weeks and three, six and 12 months postoperatively. The primary outcome measure was the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. Secondary outcome measures included a visual analogue scale (VAS) score for pain and the area of bone marrow oedema of the talus as identified on sagittal fat suppression sequence MRI scans.Aims
Methods
The aim of this study was to describe the technique of distraction
osteogenesis followed by arthrodesis using internal fixation to
manage complex conditions of the ankle, and to present the results
of this technique. Between 2008 and 2014, distraction osteogenesis followed by arthrodesis
using internal fixation was performed in 12 patients with complex
conditions of the ankle due to trauma or infection. There were eight
men and four women: their mean age was 35 years (23 to 51) at the
time of surgery. Bone healing and functional recovery were evaluated
according to the criteria described by Paley. Function was assessed
using the ankle-hindfoot scale of the American Orthopedic Foot and
Ankle Society (AOFAS).Aims
Patients and Methods
The incidence of acute and chronic conditions
of the tendo Achillis appear to be increasing. Causation is multifactorial
but the role of inherited genetic elements and the influence of
environmental factors altering gene expression are increasingly
being recognised. Certain individuals’ tendons carry specific variations
of genetic sequence that may make them more susceptible to injury.
Alterations in the structure or relative amounts of the components
of tendon and fine control of activity within the extracellular
matrix affect the response of the tendon to loading with failure
in certain cases. This review summarises present knowledge of the influence of
genetic patterns on the pathology of the tendo Achillis, with a
focus on the possible biological mechanisms by which genetic factors
are involved in the aetiology of tendon pathology. Finally, we assess
potential future developments with both the opportunities and risks
that they may carry. Cite this article:
We carried out a retrospective study to assess the clinical results of lengthening the fourth metatarsal in brachymetatarsia in 153 feet of 106 patients (100 female, six males) using three different surgical techniques. In one group lengthening was performed by one-stage intercalary bone grafting secured by an intramedullary Kirschner-wire (45 feet, 35 patients). In the second group lengthening was obtained gradually using a mini-external fixator after performing an osteotomy with a saw (59 feet, 39 patients) and in the third group lengthening was achieved in a gradual manner using a mini-external fixator after undertaking an osteotomy using osteotome through pre-drilled holes (49 feet, 32 patients). The mean age of the patients was 26.3 years (13 to 48). Pre-operatively, the fourth ray of the bone-graft group was longer than that of other two groups (p <
0.000). The clinical outcome was compared in the three groups. The mean follow-up was 22 months (7 to 55). At final follow-up, the mean lengthening in the bone-graft group was 13.9 mm (3.5 to 23.0, 27.1%) which was less than that obtained in the saw group with a mean of 17.8 mm (7.0 to 33.0, 29.9%) and in the pre-drilled osteotome group with a mean of 16.8 mm (6.5 to 28.0, 29.4%, p = 0.001). However, the mean time required for retention of the fixation in the bone-graft group was the shortest of the three groups. Patients were dissatisfied with the result for five feet (11.1%) in the bone-graft group, eight (13.6%) in the saw group and none in the pre-drilled osteotomy group (p <
0.000). The saw group included eight feet with failure of bone formation after surgery. Additional operations were performed in 20 feet because of stiffness (n = 7, all groups), failure of bone formation (n = 4, saw group), skin maceration (n = 4, bone-graft group), malunion (n = 4, bone-graft and saw groups) and breakage of the external fixator (n = 1, saw group). We conclude that the gradual lengthening by distraction osteogenesis after osteotomy using an osteotome produces the most reliable results for the treatment of fourth brachymetatarsia.
We present a series of 16 patients treated between 1993 and 2006 who had a failed total ankle replacement converted to an arthrodesis using bone grafting with internal fixation. We used tricortical autograft from the iliac crest to preserve the height of the ankle, the malleoli and the subtalar joint. A successful arthrodesis was achieved at a mean of three months (1.5 to 4.5) in all patients except one, with rheumatoid arthritis and severe bone loss, who developed a nonunion and required further fixation with an intramedullary nail at one year after surgery, before obtaining satisfactory fusion. The post-operative American Orthopaedic Foot and Ankle Society score improved to a mean of 70 (41 to 87) with good patient satisfaction. From this series and an extensive review of the literature we have found that rates of fusion after failed total ankle replacement in patients with degenerative arthritis are high. We recommend our method of arthrodesis in this group of patients. A higher rate of nonunion is associated with rheumatoid arthritis which should be treated differently.
