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
The morphology of medial malleolar fracture is highly variable and difficult to characterize without 3D reconstruction. There is also no universally accepeted classification system. Thus, we aimed to characterize fracture patterns of the medial malleolus and propose a classification scheme based on 3D CT reconstruction. We retrospectively reviewed 537 consecutive cases of ankle fractures involving the medial malleolus treated in our institution. 3D fracture maps were produced by superimposing all the fracture lines onto a standard template. We sliced fracture fragments and the standard template based on selected sagittal and coronal planes to create 2D fracture maps, where angles α and β were measured. Angles α and β were defined as the acute angles formed by the fracture line and the horizontal line on the selected planes.Aims
Methods
It has been suggested that extracorporeal shockwave
therapy is a safe and effective treatment for pain relief from recalcitrant
plantar fasciopathy (PF). However, the changes in gait and associated
biomechanical parameters have not been well characterised. We recruited
12 female patients with recalcitrant PF who had a mean age of 59
years (50 to 70) and mean body mass index of 25 kg/m2 (22
to 30). The patients reported a mean duration of symptoms of 9.3
months (6 to 15). Shockwave therapy consisting of 1500 impulses
(energy flux density 0.26 mJ/mm2) was applied for three
sessions, each three weeks apart. A pain visual analogue scale (VAS)
rating, plantar pressure assessment and motion analysis were carried
out before and nine weeks after first shock wave therapy. It was demonstrated
that patients increased their walking velocity and cadence as well
indicating a decrease in pain after shockwave therapy. In the symptomatic
foot, the peak contact pressure over the forefoot increased and
the contact area over the digits decreased. The total foot impulse
also decreased as did stance duration. The duration the centre of
pressure remained in the hindfoot increased in the symptomatic foot
after shockwave therapy. The differences in centre of pressure trajectory
at baseline decreased at final follow-up. In conclusion, shockwave
therapy not only decreased the pain VAS rating but also improved
the gait parameters of the symptomatic foot in PF patients. Cite this article:
The AO Foundation advocates the use of partially
threaded lag screws in the fixation of fractures of the medial malleolus.
However, their threads often bypass the radiodense physeal scar
of the distal tibia, possibly failing to obtain more secure purchase
and better compression of the fracture. We therefore hypothesised that the partially threaded screws
commonly used to fix a medial malleolar fracture often provide suboptimal
compression as a result of bypassing the physeal scar, and proposed
that better compression of the fracture may be achieved with shorter
partially threaded screws or fully threaded screws whose threads
engage the physeal scar. We analysed compression at the fracture site in human cadaver
medial malleoli treated with either 30 mm or 45 mm long partially
threaded screws or 45 mm fully threaded screws. The median compression
at the fracture site achieved with 30 mm partially threaded screws
(0.95 kg/cm2 (interquartile range (IQR) 0.8 to 1.2) and
45 mm fully threaded screws
(1.0 kg/cm2 (IQR 0.7 to 2.8)) was significantly higher
than that achieved with 45 mm partially threaded screws (0.6 kg/cm2 (IQR
0.2 to 0.9)) (p = 0.04 and p <
0.001, respectively). The fully
threaded screws and the 30mm partially threaded screws were seen
to engage the physeal scar under an image intensifier in each case. The results support the use of 30 mm partially threaded or 45
mm fully threaded screws that engage the physeal scar rather than
longer partially threaded screws that do not. A
45 mm fully threaded screw may in practice offer additional benefit
over 30 mm partially threaded screws in increasing the thread count
in the denser paraphyseal region. Cite this article:
The aim of this study was to report a single surgeon series of
consecutive patients with moderate hallux valgus managed with a
percutaneous extra-articular reverse-L chevron (PERC) osteotomy. A total of 38 patients underwent 45 procedures. There were 35
women and three men. The mean age of the patients was 48 years (17
to 69). An additional percutaneous Akin osteotomy was performed
in 37 feet and percutaneous lateral capsular release was performed
in 22 feet. Clinical and radiological assessments included the type
of forefoot, range of movement, the American Orthopedic Foot and
Ankle (AOFAS) score, a subjective rating and radiological parameters. The mean follow-up was 59.1 months (45.9 to 75.2). No patients
were lost to follow-up.Aims
