The purpose of this study was to evaluate total hip arthroplasty (THA) in the treatment of post-traumatic arthritis following acetabular fracture and to compare the long-term outcome of THA after previous open reduction and internal fixation (ORIF) or conservative treatment of the acetabular fracture. Thirty-four patients (thirty-six hips) underwent total hip arthroplasty for arthritis resulting from acetabular fractures. There were twenty-six males (27 hips) and eight females (9 hips). The mean age at the time of hip arthroplasty was 49 years (range, 25-78 years). The mean follow-up was eight years and nine months (range, 4-17 years). The mean interval from fracture to arthroplasty was 7.5 years (range, 5 months-29 years). Two patients died of unrelated causes and two patients were lost to follow-up. Thirty patients (32 hips) were available for latest follow-up. Twenty-one hips had been previously treated by open reduction internal fixation and 11 hips had conservative treatment. Sixteen patients achieved and maintained a good to excellent result over the course of the follow-up. There was no difference in improvement of mean Harris Hip Score between both groups (p>0.05). Ten out of 32 hips required revision; 9 acetabular components were revised because of aseptic loosening (3), osteolysis/excessive wear (4), instability (1) and infection (1) with a total revision rate of 28%. Eight patients needed acetabular revision alone, one femoral revision alone and one revision of both components. There was no significant difference in bone grafting, heterotopic bone formation, revision rate, operative time and blood loss between the two groups (p> 0.05). Those patients initially treated conservatively had similar long term results compared to those treated primarily by open reduction internal fixation. At long term follow-up the main problem identified was osteolysis and acetabular wear.
The Ilizarov method for non-union comprises a range of treatment protocols designed to generate tissue, correct deformity, eradicate infection and secure union. The choice of specific reconstruction method is difficult, but should depend on the biological and mechanical needs of the non-union. We present a prospective series of patients with non-union of the tibia managed using a treatment algorithm based on the Ilizarov method and the viability of the non-union. Forty-four patients (34 men and 10 women) were treated with 26 viable and 18 non-viable non-unions. Mean duration of non-union was 19 months (range 2-168). 25 patients had associated limb deformity and 37 cases were infected. 42 patients had undergone at least one previous operation. Bone resection was dictated by the presence of non-viable and infected tissue. Four Ilizarov protocols were used (monofocal distraction in 18 cases, monofocal compression in 11 cases, bifocal compression-distraction in 10 cases and 5 bone transports) depending on the stiffness of the non-union or the presence of segmental defect.Introduction

Ankle fusion presents a difficult problem in the presence of infection, inadequate soft tissue, poor bone stock and deformity. Nonunion and infection remains a problem even with internal fixation. Ilizarov frame provides an elegant solution to the problem with stable remote fixation while allowing lengthening, deformity correction and weight bearing. Twenty-one consecutive patients were studied. The mean age at onset of disease was 52 years (range 4-70). Mean duration of the problem was 59.9 months (6-372). Aetiology included traumatic arthritis in 5, traumatic arthritis with osteomyelitis in 1, failed ankle fusion in 8, septic arthritis in 1, infected ankle fracture nonunion in 1, avascular necrosis of talus in 1, congenital deformity in 3 and failed ankle arthroplasty in 1. 15 patients had deformity of the ankle at the time of presentation. 15 of the 21 patients had either clinical or radiological evidence of infection. Treatment principles involved local excision, deformity correction with good alignment and soft tissue management. Static Compression was achieved with an Ilizarov frame while dynamic fixation was performed in 3 cases for lengthening. Antibiotics treatment was continued until union in the infected cases. On achieving union the frame was removed and a below knee cast was applied for 4 weeks.Introduction

The incidence of cervical spine injuries associated with facial fractures varies from study to study. The presence or absence of a cervical spine injury has important implications in trauma patients, influencing airway management techniques, choice of diagnostic imaging studies, surgical approach and timing for repair of concomitant facial fractures. There is general agreement that immediate management of cervical spine injuries is mandatory to prevent further neurological injury. Nevertheless, disagreement exists as to the actual incidence of cervical spinal trauma in conjunction with various facial fracture patterns. The purpose of this study was to review the incidence of cervical spine injury associated with various upper, middle and lower one-third facial fractures presenting to St. Michael's Hospital Regional Trauma Centre. A retrospective chart review was performed of patients presenting to the Trauma Service at St. Michael's Hospital from 1 January 1993 to 31 December 2003 inclusive. The data from this 10 year time span revealed a total of 124 patients with cervical spine injuries drawn from a cohort of 3,356 patients with craniomaxillofacial fractures. The overall incidence of cervical spine injury was 3.7%. Isolated upper 1/3 facial and skull fractures accounted for 1,711 of the patients and were associated with cervical spine injury in .53% of cases, while isolated middle 1/3 facial fractures were seen in 1,154 patients and were associated with a 1.13% rate of cervical injuries. The largest rate of association for cervical spine injury and isolated fractures was seen with lower 1/3 facial fractures at 1.51%. In contrast, combined facial fracture patterns involving two or more facial thirds accounted for the great majority of cervical spine injuries occurring at an incidence of 7.1%. The implications for trauma assessment, diagnosis and treatment of these injuries are reviewed.
