Purpose

The purpose of this study was to prospectively evaluate the rehabilitation outcome of children following operative and non-operative stabilisation of long bone fractures sustained in conjunction with an acquired brain injury (ABI).

To evaluate efficacy and outcome of embolisation following pelvic ring injuries in patients presented with ongoing hypovolaemic shock.

Between 2000 and 2003, 200 poly-trauma patients presented in our institutions following pelvic ring injuries. Those with ongoing hypovolaemic shock who were treated within 24h of admission with embolisation were included in this study. Demographics, mechanism of injury, ISS, type of pelvic ring fracture, arterial source of bleeding, hours from injury to embolisation, and outcome were all recorded prospectively. Out of the 200 treated in our institutions 17 (8.5%) underwent angio-embolisation. The mean age of the patients was 37 (14-70) and the mean ISS was 29. Distribution of pelvic ring injuries included: 3LC, 7APC, 7VS. The mean time from injury to embolisation was 15 hours. 8/17 patients were initially treated with an external fixator.

The distribution of arterial injuries was: 7 superior gluteal arteries, 8 internal iliac arteries, 1 obturator artery and 1 internal pudental artery. The mean number of units transfused prior to embolisation was 22 (range 6-50). Mortality rate was 4 (23%) out of 17 embolised patients. Angio-embolisation for pelvic ring injuries occurred in 8.5% of our study population.

This study indicates that only a small proportion of patients required embolisation secondary to arterial bleeding. The overall survival rate was in accordance to published international experience. Embolisation should be considered as a valid adjunct in some selected group of patients with pelvic fractures where ongoing bleeding refractory to other treatment modalities is present.

The purpose of this study was to evaluate the efficacy of human recombinant osteogenic protein 1 (rhBMP-7) for the treatment of fracture non-unions and to estimate the health economics aspect of its administration.

Twenty-four patients (18 males, mean age 39.1 (range 18-79)) with 25 fracture non-unions were treated with rhBMP-7 in our institution (mean follow-up 15.4 months (range 6-29)). Successful completion of treatment was defined as the achievement of both clinical and radiological union. The cost of each treatment episode was estimated including hospital stay, theatre time, orthopaedic implants, drug administration, investigations, clinic attendances, and physiotherapy treatments. The total cost of all episodes up to the point of receiving BMP-7 and similarly following treatment with BMP-7 were estimated and analysed.

Of the 25 cases, 21 were atrophic (3 associated with bone loss) and 4 were infected non-unions. The mean number of operations performed prior to rhBMP-7 application was 3.4, including autologous bone graft in 9 cases and bone marrow injection in one case. In 21 out of the 25 cases (84%), both clinical and radiological union occurred. Mean hospital stay before and after receiving rhBMP-7 was 26.84 days per fracture and 7.8 days per fracture respectively. Total cost of treatments prior to BMP-7 was £346,117 [£13,844.68 per fracture]. Costs incurred following BMP-7 administration were estimated as £183,460 [£7,338.4 per fracture].

rhBMP-7 was used as a bone stimulating agent with or without conventional bone grafting with a success rate of 84% in this series of patients with persistent fracture non-unions. The average cost of its application was £7,338 [53.0% of the total costs of previous unsuccessful treatment of non –unions, p<0.05). Treating non-union is costly, but the financial burden could be reduced by early rhBMP-7 administration when a complicated or persistent non-union is present or anticipated. Therefore, this study supports the view that rhBMP-7 is a safe and power adjunct to be considered in the surgeon's armamentarium for the management of such difficult cases.

We aimed to investigate the treatment and outcome of patients over 65 years of age with tibial Pilon fracture. Patients were treated by primary open reduction and internal fixation or external fixation (EF) as determined by local soft tissue conditions. Patient course, incidence of radiological osteoarthritis and functional outcome using the SF-36 questionnaire were recorded. All patients were evaluated serially until discharge from final follow-up. The mean follow-up time was 28 months (12-45). Statistical analysis was performed using Analyse-it(tm) software for Excel.

In total 25 patients were studied. Two patients died before completion of treatment and were excluded from the final analysis. Therefore, 23 patients (10 male) were included with a mean age of 70.9 years (range 66-89) and a mean ISS of 10.25 (range 9-22). There were 4 grade IIIb open injuries.

Three patients suffered superficial tibial wound infection. Two patients underwent early secondary amputation due to deep bone sepsis within 8 weeks of injury. One patient in the ORIF group underwent primary arthrodesis, which was subsequently revised due to non-union. 3 patients underwent secondary bone grafting to enhance healing, performed at 2, 6 and 9 weeks. 2 patients with metal work failure underwent subsequent revision of ORIF and progressed to union; the mean time to union was 33.8 weeks. At final follow-up 7 (28%) patients had radiological features of osteoarthritis but none had symptoms severe enough to warrant ankle arthrodesis. There were significant differences from the USA norm in physical function score, role physical score, and physical component score, (p< 0.01).

We aimed to quantify the health related quality of life in a series of patients suffering a variety of different tibial injuries. Patients with previous tibial injury, randomly selected from our trauma database, who successfully completed their entire course of treatment at our institution, were recalled for final assessment. Mean time to final follow-up was 37.4 months. Statistical analysis was performed using SPSS computer software.

Overall, 130 patients were evaluated. There was no significant difference in the self-care dimension between the groups. Psychological problems were common in patients with IIIb and IIIc fractures, as well as amputees, with the highest incidence in those with IIIc fractures. Patients who had undergone amputation and those with IIIb open fractures reported problems with mobility significantly more frequently than those who had IIIc type injuries. However, this could be partially attributed to the significant difference in mean age between groups, with patients sustaining IIIc injuries being younger (31.9 vs 46.9). Patients with IIIb and IIIc type fractures reported significantly more problems with pain compared with those who had undergone amputation. Interestingly, patients who had undergone fasciotomy reported pain as frequently as amputees. Regarding the VAS, only patients with closed fractures reported significantly different scores from the mean of all the other groups.

These data represent the health related quality of life of patients having suffered the full spectrum of tibial injury and should be considered when determining the treatment options for these patients.

A study to evaluate the efficacy of combined grafting (iliac crest autograft – ICAG, and human recombinant osteogenic protein 1 – rhOP1/BMP7) for long bone fracture non-unions (LBFNUs).

At both institutions prospective and retrospective data were collected. (Between Oct 2001 and Aug 2004 all LBFNUs that were grafted with a combination of BMP7 and ICAG). The records of the initial injury incident, treatment course, all operative interventions before and after the combined grafting and the follow up till final clinical & radiological union have been analysed. X2 test was used to analyse the results.

Forty-nine patients (31 males) with a mean age of 43 years (18–79) with LBFNUs were identified. The mean follow-up was 21.4 months (12–65). 7 were humeral, 13 femoral, and 29 tibial LBFNUs. Eleven were open (3 grade II, 8 grade IIIa–b). All non-unions were atrophic, and 8 had significant bone defects. The mean number of operations prior to the combined grafting was 2.5 (0–6). Clinical and Radiological union occurred within a mean time of 4.4 (3–12) months and 5.4 (4–16) months respectively. All of the fractures united. One patient, with an infected tibial non-union after an open fracture, ultimately underwent a below knee amputation. No complications or adverse effects from the use of BMP-7 were encountered.

BMP-7 was used as a bone-stimulating agent combined with conventional iliac crest bone grafting with a success rate of 98% in this series of patients with LBFNUs. This study supports the view that this combination of BMP-7 is safe and a power adjunct to be considered in the surgeon’s armamentarium for the management of such difficult cases.

Purpose: The purpose of this study was to evaluate the efficacy of a combined application of iliac crest autograft (ICAG) and human recombinant osteogenic protein 1 (BMP-7) for the treatment of non-unions of long bones fractures (LBF).

Patients and Methods: At both institutions we have prospectively and retrospectively collected and analysed data of patients admitted between October 2001 and August 2004 with a LBF nonunion (humerus, femur, tibia) and whose nonunion sites have been grafted with a combination of BMP7 and ICAG. All the records of the patients’ initial injury incident and treatment course, together with following operative interventions till and after the BMP7 application, and their follow up till final union have been analysed. Painless full weight bearing or use of the upper limp in the case of humerus (clinical union), and presence of bridging callous of two cortices visible on two x-ray views (radiological union). Chi square test was used to analyse the results.

Results: Forty-nine patients (31 males) with a mean age of 43 years (18–79) with LBF non-unions were identified. The mean follow-up was 21.4 months (range 12–65). 7 were humerus, 13 femurs, and 29 tibias. Eleven cases were open (3 grade II, and 8 grade IIIa-b). All non-unions were atrophic, and 8 were initially associated with bone loss. The mean number of operations performed prior to the combined ICAG and BMP7 application was 2.5 (0–6), including ICAG in 12 cases and bone marrow injection in 1 case. All but one of the fractures have united. Clinical and Radiological union occurred within a mean time of 4.4 (3–12) months and 5.4 (4–16) months respectively. One patient, with an infected tibial non-union following an open fracture, ultimately underwent a below knee amputation, secondary to recurrence of deep sepsis. The only patient whose (tibial) fracture has not still united is currently on an Ilizarov frame and slow progression has been reported following a recent CT. No complications or adverse effects from the use of BMP-7 were encountered.

Conclusion: BMP-7 was used as a bone stimulating agent combined with conventional iliac crest bone grafting with a success rate of 98% in this series of patients with LBF non-unions. This study supports the view that this combination of BMP-7 is safe and a power adjunct to be considered in the surgeon’s armamentarium for the management of such difficult cases.
