Introduction

Advances in the management of open tibial fractures have reduced the incidence of long-term complications of these injuries. However, a number of patients continue to suffer from sequelae such as infection, non-union and malunion. Many orthopaedic surgeons believe a below-knee amputation with a well-fitted prosthesis is a better alternative to limb reconstruction surgery. There are few studies that evaluate the long-term functional outcomes of amputees against patients who have undergone limb salvage procedures, and their results are conflicting. The hypothesis of this study is that patients who have undergone limb salvage have as good or better outcomes than those who have had below-knee amputations.

Methods

This is a retrospective case study. One group (n=12) had been treated with below-knee amputation following a variety of lower limb fractures. The other group (n=11) had developed complications following tibial fractures and undergone limb salvage surgery using the Ilizarov method. The groups were compared by means of a postal questionnaire, comprising the Oswestry Disability Index and the SF-36 Health Survey.

Introduction: Nonunion is a relatively common complication seen in orthopaedic practice. The treatment of nonunion has traditionally been revision fixation with autogenic bone grafting. Here we present our results of nonunion treatment using Osteogenic Protein -1 (OP1) and allograft paste.

Material and Methods: Forty Eight Patients with resistant nonunion including atropic, hypertrophic and infected nonunion were treated with a composite of osteogenic protein-1 and allograft paste. The series consisted of 28 males and twenty females. Average age was 54 years. The average duration of preoperative symptoms was 26 months (range 4 to 52). 28 of 48 patients had an average of three prior failed surgical attempts at union (range 1 to 6). There were thirty seven atrophic, four hypertrophic and seven infected nonunions (bone transport docking site nonunion).18 patients in the series had previous autogenic cancellous bone grafting to the fracture site for attempted union. 39 patients had revision internal fixation with application of OP-1 and allograft paste to the nonunion site. Average healing time was 6.5 months (Range 3.5–19). Three patients in this series had OP-1 insertion twice, one patient simultaneously had autogenic cancellous bone grafting with OP-1.

Results: Average follow-up was 16 months (range 4 to 38). Functional and radiological outcome was excellent in 33 patients, good in five patients and fair in three. 3 cases were ongoing. Three patients went on to non-union requiring revision surgery and are under review. One patient died during follow-up.

Conclusion: Results in our series indicate OP-1 (BMP-7) implanted with Opteform allograft paste are as effective as autogenic cancellous bone grafting in treating resistant bone nonunions.

Introduction: Ilizarov frames are widely used as an external fixation system. Whether applied for trauma, bone transport or deformity-correction they are usually applied for a minimum of three months and can be used for over a year. The psychological and lifestyle impact of frames has been shown to be significant.

Purpose: We examined the informational needs of patients with Ilizarov frames pre and post-operatively. We then assessed how these needs are met by the provision of a nurse-led support group.

Methods: All patients with Ilizarov frames applied at Hope Hospital, Manchester were contacted by postal questionnaire. Questions were asked about preparation before surgery, changes to lifestyle and information received. Specific questions were asked about attendance at the nurse-led Ilizarov support group.

Results: Thirty-seven patients replied. Twenty-two had frames on and fifteen had recently had them removed. Most patients reported feeling well prepared before surgery regarding the likely impact on their lives. Two-thirds (twenty-five) felt they had received adequate information. Three-quarters (twenty-six) patients had attended the Ilizarov support group and most (twenty-one) had attended the group pre¬operatively. Over three-quarters of patients agreed they would attend the group with a “frame problem” before attending their own GP. All patients found the group supportive and felt comfortable discussing their problems.

Conclusion: The Ilizarov Support Group is a useful resource for people with frames. The group atmosphere is supportive to patients and it is a valuable problem-solving environment. It helps patients prepare for their surgery and reduces attendance to primary care providers for frame related problems. We suggest other Ilizarov units may benefit from the provision of such a service.

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.

Introduction: While the early period of distraction osteogenesis has been extensively investigated, there are no data describing the long-term morphology of the regenerate. Patients and Methods: We performed MRI scans to ten adults, seven of which had bone transport for an osseous defect while further three had lengthening for limb length discrepancy. Follow up ranged between 14 and 43 months (mean: 29 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. Results: 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), which associated increase in the signal intensity (p< 0.003). Finally in cases that underwent bone transport, the docking site was noted to be obstructed by unhydrated tissue. Conclusions: 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 preoperative counselling but also for considering treatment modalities in case of a fracture.
