Background

To determine the relative contributions of bilateral versus unilateral femoral shaft fracture plus injuries in other body regions to mortality after injury.

If the lower re-rupture in operative treated patients was an effect of tendon-end apposition, then patients in whom that could be demonstrated in equinus by ultrasound could be equally well treated non-operatively without the attendant surgical risk.

All patients undergoing ultrasound for a suspected Achilles tendon repair between January 2000-2005 were included. Patients with a residual gap, 5mm or more in equinus; were treated by surgical repair. Those with a gap of less than 5mm were treated non-operatively. We excluded patients with no rupture, partial rupture and musculo-tendinuous junction (MTJ) tears. We recorded the following: clinical findings, ultrasound measurements of tendon gap in neutral and equinus, distance of rupture from distal insertion, the treatment and complications. All patients were followed up to a minimum of 6 months.

156 patients were treated for a clinical Achilles tendon rupture during the study period. We excluded 5 patients with no rupture on ultrasound, 15 with a MTJ tear, 7 with a muscle tear and 4 patients did not follow the protocol. 125 patients comprising 88 males and 37 females were entered into the study. 67 patients were treated operatively (37 open, 30 percutaneous) and 58 non-operatively. There was no significant difference between the 2 groups with respect to age, sex and injury mechanism. Two patients in the non-operative group had a re-rupture (3.4%) compared with 1 (1.5%) in the non-operative group. There were 2 incidences of superficial wound infection and 2 of temporary dorsal foot numbness in the operative. One patient in the non-operative group had a DVT. There was no significant difference for any of the complications between the two groups.

It may be possible to reduce the risk of re-rupture and surgery using dynamic ultrasound to determine which treatment the patient receives.

Background

Referral to centres with a pelvic service is standard practice for the management of displaced acetabular fractures.

Background: The safest and most effective method of early spine clearance in unconscious patients is the subject of intense debate.

Hypothesis: Helical CT is a sufficiently sensitive investigation to render dynamic screening of the cervical spine redundant.

Protocol: Our protocol for cervical spinal clearance in the unconscious patient since April 1994 involves the use of plain radiographs, CT scan (helical CT since 1997) and dynamic screening (DS).

Method: Over a ten-year period, April 1994 to September 2004, 839 patients were admitted to intensive care under the orthopaedic surgeons. 35 patients were excluded because of incomplete records.

Results:

Demographics: The mechanism of injury was a road traffic accident in 80% and the mean ISS was 24.1. There were 95 patients (10.9%) with a cervical spine fracture, 96 (10.8%) with a fracture in either / both thoracic and lumbar regions.

Conclusion: DS is a safe procedure but has no real advantage over helical CT. Power’s ratio calculation is essential to reduce the chance of a missing an upper cervical injury. The cervical spine can be reliably cleared using helical CT alone.

Hypothesis: If the lower re-rupture in operative treated patients was an effect of tendon-end apposition, then patients in whom that could be demonstrated in equinus by ultrasound could be equally well treated non-operatively without the attendant surgical risk.

Method: All patients undergoing ultrasound for a suspected Achilles tendon repair between January 2000 – 2005 were included. Patients with a residual gap, 5mm or more in equinus; were treated by surgical repair. Those with a gap of less than 5mm were treated non-operatively. We excluded patients with no rupture, partial rupture and musculo-tendinuous junction (MTJ) tears. We recorded the following: clinical findings, ultrasound measurements of tendon gap in neutral and equinus, distance of rupture from distal insertion, the treatment and complications. All patients were followed up to a minimum of 6 months.

Results: 156 patients were treated for a clinical Achilles tendon rupture during the study period. We excluded 5 patients with no rupture, 15 with a MTJ tear, 7 with a muscle tear and 4 patients did not follow the protocol. 125 patients comprising 88 males and 37 females were entered into the study. 67 patients were treated operatively (37 open, 30 percutaneous) and 58 non-operatively. There was no significant difference between the 2 groups with respect to age, sex and injury mechanism. There were 2 re-ruptures in the non-operative group and 1 with surgery. The operative group had 2 patients with superficial wound infection and 2 with temporary dorsal foot numbness. One patient in the non-operative group had a DVT. There was no significant difference for any of the complications between the two groups.

Conclusions: It may be possible to reduce the risk of re-rupture and surgery using dynamic ultrasound to determine which treatment the patient receives.

This is a retrospective case review of 237 patients with displaced fractures of the acetabulum presenting over a ten-year period, with a minimum follow-up of two years, who were studied to test the hypothesis that the time to surgery was predictive of radiological and functional outcome and varied with the pattern of fracture. Patients were divided into two groups based on the fracture pattern: elementary or associated. The time to surgery was analysed as both a continuous and a categorical variable. The primary outcome measures were the quality of reduction and functional outcome. Logistic regression analysis was used to test our hypothesis, while controlling for potential confounding variables.

For elementary fractures, an increase in the time to surgery of one day reduced the odds of an excellent/good functional result by 15% (p = 0.001) and of an anatomical reduction by 18% (p = 0.0001). For associated fractures, the odds of obtaining an excellent/good result were reduced by 19% (p = 0.0001) and an anatomical reduction by 18% (p = 0.0001) per day.

When time was measured as a categorical variable, an anatomical reduction was more likely if surgery was performed within 15 days (elementary) and five days (associated). An excellent/good functional outcome was more likely when surgery was performed within 15 days (elementary) and ten days (associated).

The time to surgery is a significant predictor of radiological and functional outcome for both elementary and associated displaced fractures of the acetabulum. The organisation of regional trauma services must be capable of satisfying these time-dependent requirements to achieve optimal patient outcomes.

Advances in the design of the components for total ankle replacement have led to a resurgence of interest in this procedure.

Between January 1999 and December 2004, 16 patients with a failed total ankle replacement were referred to our unit. In the presence of infection, a two-stage salvage procedure was planned. The first involved the removal of the components and the insertion of a cement spacer. Definitive treatment options included hindfoot fusion with a circular frame or amputation. When there was no infection, a one-stage salvage procedure was planned. Options included hindfoot fusion with an intramedullary nail or revision total ankle replacement. When there was suspicion of infection, a percutaneous biopsy was performed. The patients were followed up for a minimum of 12 months.

Of the 16 patients, 14 had aseptic loosening, five of whom underwent a revision total ankle replacement and nine a hindfoot fusion. Of the two with infection, one underwent fusion and the other a below-knee amputation. There were no cases of wound breakdown, nonunion or malunion.

Management of the failed total ankle replacement should be performed by experienced surgeons and ideally in units where multidisciplinary support is available. Currently, a hindfoot fusion appears to be preferable to a revision total ankle replacement.

Method: We reviewed the hospital notes of 45 patients who underwent a lumbar discectomy over a 30month period. The care pathway was divided into three components: Pre-Hospital Wait (time from GP referral to first outpatient appointment), Hospital Wait (first out-patient appointment to being listed for surgery) and the Waiting List period.

The patients were divided into three groups: those following a standard pathway (group I), patients referred with an MRI scan (group II) and emergency admissions to hospital (group III).

Results: The groups I, II and III comprised of 18, 12 and 7 patients respectively. The mean Pre-Hospital Wait in weeks was 16 (group I) and 14 (group II). The Hospital Wait was 12 (group I), 3 (group II) and 1 (group III). The Waiting List period was 26 (group I), 18 (group II) and 1 (group III). The difference in The Hospital Wait between groups I and II reached significance.

Discussion: The Waiting List Period is often blamed as the causa principale for a delay in treatment. This review shows that a considerable time is spent in the Hospital Wait period and draws attention to a recognised delay in the care pathway, which requires a multidisciplinary approach to reduce its effect.

Aims: To assess the value of hip arthrography in planning definitive treatment for children with DDH and Perthes’ disease.

Background: It is sometimes unclear whether children with DDH and Perthes’ disease need an operation. Surgeons are guided by the clinical symptoms and signs together with the radiographic appearances of the affected hip. In our Unit children on whom an operation is considered undergo an examination under anaesthetic (EUA) and a hip arthrogram. This prospective study was developed to assess whether treatment was modified by the arthrogram.

Methods: All patients who underwent an EUA and hip arthrogram for DDH or Perthes’ disease over a 10 month period were entered into this prospective study. Prior to arthrography a Consultant Children’s Orthopaedic Surgeon formulated a treatment plan. A standard arthrogram was performed which included anteroposterior, frog lateral, Von Rosen and oblique views. Traction axial loading views were taken to assess stability. Following EUA and arthrogram the Consultant Surgeon formulated a definitive treatment plan. Three Children’s Consultants were then invited subsequently to review the preoperative and arthrographic appearances blindly to monitor reproducibility. Twenty-one patients with DDH and 19 with Perthes’ disease were entered into the study.

Results: In the DDH group of patients the treatment plan was modified in 12 of the 21 patients as a consequence of the arthrogram. Six of the 19 patients (31.6 %) of the Perthes’ affected patients had their treatment modified. When it was felt likely prior to EUA a conservative treatment was indicated. The correlation of intra-observer Consultant agreement was high but inter-observer Consultant agreement was moderate only. In both groups of patients the range of hip motion was significantly greater under anaesthesia.

Conclusion: Static and dynamic arthrography helps decision making in patients with DDH and Perthes’ disease.
