We report a prospective study of 106 consecutive patients younger than 60 years old who suffered an intertrochanteric fracture of the proximal femur and were treated with an “Ilizarov” external fixator. All surviving patients were assessed with the assistance of the “CITO” evaluation system for fracture outcomes at three months post-injury and 73 patients were either clinically reviewed or contacted by a letter to establish the long-term results.

Complications included one intraoperative death, one case of post-traumatic ankylosis of the hip, two cases that were discharged in varus and one case in valgus of the femoral neck. Other complications included pin-track infections and stiffness at the level of the knee that required a year to resolve. Overall long-term satisfaction was high (76% in reviewed patients and 91% in patients contacted by letter).

The advantages of the “Ilizarov” external fixator include minimal disruption of the tissues and blood loss, capability of closed reduction of the fractures as well as post-operative manipulation of the fracture by gradual adjustments of the frame. This method, however, is time consuming, requires expertise and intense follow-up during the immediate post-operative period.

While the early period of distraction osteogenesis has been extensively investigated, there are very few data describing the long-term morphology of the regenerate. We performed magnetic resonance scans in ten adults (men age 35+− 11 yr), seven of whom had bone transport for an iatrogenic osseous defect while further three had tibial lengthening for limb length discrepancy. Follow-up ranged between 14 and 43 months (mean : 28 + − 10 months) following the removal of the external fixator. The perimeter, cross- sectional area, volume and the mean signal intensity was calculated from the obtained T1 weighted axial images. Values were compared with the contralateral tibia that acted as control. All cases that had bone transport increased the volume of the tibia from 15.3% up to 50.8%. The regenerated segment was noted to have expanded significantly (p< 0.0001) in all cases. Mean signal intensity in the regenerate decreased in seven cases significantly (p< 0.0001) suggesting increase content of unhydrated tissue such as bone and collagen. The cross-sectional surface of the transported segment was increased in all cases (p< 0.008). Finally in cases that underwent bone transport, the docking site was noted to be obstructed by unhydrated tissue. Contrary to previous claims, the post-distraction osteogenesis tibia is far from normal, consisting of areas with potentially different biomechanical properties. Recognition of these changes is essential not only for appropriate pre-operative counselling but also for considering treatment modalities in case of a fracture.

We present our technique for arthrodesis of the failed Keller’s excisional arthroplasty and the results of postoperative follow-up in a series of eight patients [nine feet].

Arthrodesis of the first metatarsophalangeal joint was performed with a tricortical interposition bone graft stabilised between the first metatarsal and proximal phalanx with a mini dental plate. In all cases the indication for the procedure was for chronic pain at the first meta-tarsophalangeal joint and transfer metatarsalgia of the lateral rays. Post-operative follow-up ranged from 13– 70 months and patients were evaluated using a custom-made satisfaction questionnaire, clinical examination and evaluation of pre-and post-operative x-rays.

All patients were female. The mean age of the patients was 53.2 years [range 32–69]. The post- operative questionnaire revealed that five patients [six cases] were highly satisfied with the surgery. However, we do report complications associated with the procedure including one case of deep infection and four cases in total of radiological non-union of the graft.

The majority of patients were highly satisfied with the surgery, but this technique for the revision of failed Keller’s procedures has a significant risk of complications, so patients should receive appropriate counselling pre-operatively. Although the mini dental plate was low profile, its decreased rigidity may have been responsible for the four cases of non-union.

Aims: To report the outcome of secondary patellar resurfacing in patients with chronic anterior knee pain following primary total knee replacement. Methods: A total of twenty patients identified over a 10-year period from 623 patients managed without patellar replacement during primary knee arthroplasty were included and evaluated pre and postoperatively using the American Knee Society (AKS) score, as well as by radiological analysis. Results: The mean follow up was 36.1 months (range 12–104 months). The mean knee score improved from 46.7 to 62.2 points while the mean functional score increased from 44.7 to 52.2 points. Only 44.5% of the patients reported some improvement whereas the remaining reported no change or deterioration. Postoperative radiographic alignment of the primary knee arthroplasty did not influence outcome of secondary patellar resurfacing. Complications were noted in 6 of the 20 patients including patella fracture, patella instability and loss of a range of movement. Conclusions: Anterior knee pain following knee arthroplasty remains a difficult condition to manage and secondary resurfacing of the patella is clearly not to be advocated in all patients since it may well increase patient dissatisfaction and hasten revision.
