The clinical outcome was measured using Harris, Charnley, Oxford hip scores and quality of life using SF-36. Radiographs were systematically analysed for implant position, fixation, and loosening.
The clinical scores were respectively, Harris 85 (25–100), Oxford 21.5 (12–52), mean Charnley score 4.8 for pain, 5.3 for movement and 4.3 for mobility; the mean SF-36 score were 44 (12–58) for the physical and 51.4 (19–71) for the mental component. With an end point of definite or probable aseptic loosening, the probability of survival at 5 years was 100% and 97.3% (95% CI = 2.9) for acetabular and femoral components respectively. Overall survival at 5years with removal or repeat revision of either component for any reason as the end point was 91% (95% CI: 82 to 97%).
Firearm injury is a potentially increasing public health problem worldwide. It is increasingly the subject of media and public attention. We aim to analyze the epidemiology, pattern and outcome as experienced. Data such as age, sex, race, scene and nature of injury, firearm used, alcohol and drug factors, anatomy involved, surgical requirements, transfusion details, ICU/HDU stay, complications, deaths, and outcome were collected from medical notes, WYMAS and Coroners office of all patients who presented with firearm injuries from January 1995 to December 2001. Seventy-eight cases presented to our institution. There were 19 fatalities at the scene of injury. 69 were male. 51 sustained injuries in public places, 20 at their homes and 7 in outdoor areas. Low velocity firearms were involved in 49 cases. 50 were crime related. Alcohol was identified in 34 patients and illicit drugs in 6 cases. 19 cases had bony injury with associated vascular injury in one case. Primary neurological injury was diagnosed in 5 cases. Lower extremities and upper limb injuries accounted for 59% and 26%. 3 had head and neck wounds. 4 patients had thoracic trauma and 5 had abdominal injury. 86% required surgical intervention. 11 patients had a total of 16 complications, the most common being secondary infection. 6% of patients died at the emergency department and 3 after. Chest injuries caused 5 deaths and head wounds caused 3 deaths illustrating criminal intention to cause fatal body harm.
We have reviewed the patients with vertical shear fractures of the Pelvis and report on our treatment protocol and long-term functional outcome. Methods: Between January 1993 and January 2002, out of 581 pelvic ring injuries treated in our unit, we identified 31 vertical shear fractures in 29 (4.9%) patients (4 female). Data such as age, sex, aetiology, associated injuries, ISS, resuscitation and transfusion requirements were recorded. ICU/HDU stay, surgical stabilization, urological injuries, systemic complications, neurological injury and mortality were recorded and analysed. Functional outcome was assessed using the following generic tools: EuroQol EQ-5D, SF36v2, SMFA, Majeed score and VAS.
The radiologic score of degenerative hip disease (Matta 1994) for the acetabular fracture group was: four excellent, eight good, 14 fair and three poor. Analysis of the functional outcome is shown in Table 1.
We report the clinical and radiological outcome of 86 revisions of cemented hip arthroplasties using JRI-Furlong hydroxyapatite-ceramic-coated acetabular and femoral components. The acetabular component was revised in 62 hips and the femoral component in all hips. The mean follow-up was 12.6 years and no patient was lost to follow-up. The mean age of the patients was 71.2 years. The mean Harris hip and Oxford scores were 82 (59 to 96) and 23.4 (14 to 40), respectively. The mean Charnley modification of the Merle d’Aubigné and Postel score was 5 (3 to 6) for pain, 4.9 (3 to 6) for movement and 4.4 (3 to 6) for mobility. Migration of the acetabular component was seen in two hips and the mean acetabular inclination was 42.6°. The mean linear polyethylene wear was 0.05 mm/year. The mean subsidence of the femoral component was 1.9 mm and stress shielding was seen in 23 (28%) with bony ingrowth in 76 (94%). Heterotopic ossification was seen in 12 hips (15%). There were three re-revisions, two for deep sepsis and one for recurrent dislocation and there were no re-revisions for aseptic loosening. The mean EuroQol EQ-5D description scores and health thermometer scores were 0.69 (0.51 to 0.89) and 79 (54 to 95), respectively. With an end-point of definite or probable loosening, the probability of survival at 12 years was 93.9% and 95.6% for the acetabular and femoral components, respectively. Overall survival at 12 years, with removal or further revision of either component for any reason as the end-point, was 92.3%. Our study supports the continued use of this arthroplasty and documents the durability of hydroxyapatite-ceramic-coated components.
Injury to the sciatic nerve is one of the more serious complications of acetabular fracture and traumatic dislocation of the hip, both in the short and long term. We have reviewed prospectively patients, treated in our unit, for acetabular fractures who had concomitant injury to the sciatic nerve, with the aim of predicting the functional outcome after these injuries. Of 136 patients who underwent stabilisation of acetabular fractures, there were 27 (19.9%) with neurological injury. At initial presentation, 13 patients had a complete foot-drop, ten had weakness of the foot and four had burning pain and altered sensation over the dorsum of the foot. Serial electromyography (EMG) studies were performed and the degree of functional recovery was monitored using the grading system of the Medical Research Council. In nine patients with a foot-drop, there was evidence of a proximal acetabular (sciatic) and a distal knee (neck of fibula) nerve lesion, the double-crush syndrome. At the final follow-up, clinical examination and EMG studies showed full recovery in five of the ten patients with initial muscle weakness, and complete resolution in all four patients with sensory symptoms (burning pain and hyperaesthesia). There was improvement of functional capacity (motor and sensory) in two patients who presented initially with complete foot-drop. In the remaining 11 with foot-drop at presentation, including all nine with the double-crush lesion, there was no improvement in function at a mean follow-up of 4.3 years.
The aim of revision hip arthroplasty for infection is to eradicate infection and restore function. There is, in current literature, little evidence to suggest an optimal time interval between first (excision) and second (reconstruction) stage procedures in revision hip arthroplasty. Our aim was to assess the difference in outcome, in terms of patient pain, function and satisfaction, in relation to the time interval between surgeries. A prospective analysis was made of 22 consecutive patients who underwent two-stage revision total hip replacement between 1992 and 2001. There were 12 male and 10 female patients. The mean age at the time of revision surgery was 63.5 years (range 35–83 years). The indication for surgery was infection in all cases. Patients were subdivided into two groups according to the time interval between first and second stages : Group 1 – time interval 6 months or less; Group 2 – time interval greater than 1 year. Outcome was assessed at 1 year post-operatively using change in pain and function scores and patient satisfaction scores. Pre-operative pain and function scores were similar in the two Groups. Both Groups reported a similar improvement in pain at 1 year post-operatively. The patients in Group 1 also showed an improvement in function score, however, the patients in Group 2 showed no improvement in function. All patients felt the operation to be worthwhile as reflected in the patient satisfaction scores. The results suggest that good improvements in pain can be achieved after short and longer time intervals. A longer time interval may well be associated with a poorer outcome in terms of restoring function.
