In this randomized study, we aimed to compare quality of regenerate in monolateral Both groups were comparable in demographic and injury characteristics. A phantom (aluminium step wedge of increasing thickness) was designed to compare the density of regenerate on radiographs. A CT scan was performed at three and six months postoperatively to assess regenerate density. A total of 30 patients (29 male, one female; mean age 32.54 years (18 to 60)) with an infected nonunion of a tibial fracture presenting to our tertiary institute between June 2011 and April 2016 were included in the study.Aims
Patients and Methods
This is a prospective randomised study which compares the radiological
and functional outcomes of ring and rail fixators in patients with
an infected gap (>
3 cm) nonunion of the tibia. Between May 2008 and February 2013, 70 patients were treated
at our Institute for a posttraumatic osseocutaneous defect of the
tibia measuring at least 3 cm. These were randomised into two groups
of 35 patients using the lottery method. Group I patients were treated
with a ring fixator and group II patients with a rail fixator. The
mean age was 33.2 years (18 to 64) in group I and 29.3 years (18
to 65) in group II. The mean bone gap was 5.84 cm in group I and 5.78
cm in group II. The mean followup was 33.8 months in group I and 32.6 months
in group II. Bone and functional results were assessed using the
classification of the Association for the Study and Application
of the Method of Ilizarov (ASAMI). Functional results were also
assessed at six months using the short musculoskeletal functional
assessment (SMFA) score.Aims
Patients and Methods
The aim of this study was to establish a classification system for the acromioclavicular joint using cadaveric dissection and radiological analyses of both reformatted computed tomographic scans and conventional radiographs centred on the joint. This classification should be useful for planning arthroscopic procedures or introducing a needle and in prospective studies of biomechanical stresses across the joint which may be associated with the development of joint pathology. We have demonstrated three main three-dimensional morphological groups namely flat, oblique and curved, on both cadaveric examination and radiological assessment. These groups were recognised in both the coronal and axial planes and were independent of age.
Disorders of the pisotriquetral joint are well recognised as the cause of pain on the ulnar side of the wrist. The joint is not usually examined during routine arthroscopy because it is assumed to have a separate joint cavity to the radiocarpal joint, although there is often a connection between the two. We explored this connection during arthroscopy and in fresh-frozen cadaver wrists and found that in about half of the cases the pisotriquetral joint could be visualised through standard wrist portals. Four different types of connection were observed between the radiocarpal joint and the pisotriquetral joint. They ranged from a complete membrane separating the two, to no membrane at all, with various other types of connection in between. We recommend that inspection of the pisotriquetral joint should be a part of the protocol for routine arthroscopy of the wrist.
1. Two cases of haemangioma of the patella are reported. 2. In one case pain alone brought the patient for treatment; in the other, a pathological fracture was the first symptom. 3. In neither case was a firm diagnosis made before excision and histological examination of the patella. 4. In each case a good result followed removal of the patella: this is probably the best method of treatment. 5. The literature relating to haemangioma of bone and to tumours of the patella is briefly reviewed.
