Aims

Pneumatic tourniquets are often used during the surgical treatment of unstable traumatic ankle fractures. The aim of this study was to assess the risk of reoperation after open reduction and internal fixation of ankle fractures with and without the use of pneumatic tourniquets.

Aims

Distal third clavicle (DTC) fractures are increasing in incidence. Due to their instability and nonunion risk, they prove difficult to treat. Several different operative options for DTC fixation are reported but current evidence suggests variability in operative fixation. Given the lack of consensus, our objective was to determine the current epidemiological trends in DTC as well as their management within the UK.

Aims

Several previously identified patient-, injury-, and treatment-related factors are associated with the development of nonunion in distal femur fractures. However, the predictive value of these factors is not well defined. We aimed to assess the predictive ability of previously identified risk factors in the development of nonunion leading to secondary surgery in distal femur fractures.

Aims

The aim of this study was to describe the management and associated outcomes of patients sustaining a femoral hip periprosthetic fracture (PPF) in the UK population.

Aims

This study aimed to identify risk factors (patient, healthcare system, and socioeconomic) for mortality after hip fractures and estimate their relative importance. Further, we aimed to elucidate mortality and survival patterns following fractures and the duration of excess mortality.

Aims

To explore staff experiences of a multicentre pilot randomized controlled trial (RCT) comparing intramedullary nails and circular frame external fixation for segmental tibial fractures.

Quality of cementation in the early postoperative period has been proven to be an indicator of long-term survival of the total hip arthroplasty. Cementation grading described by Barrack et al is widely used but has certain limitations. It is based upon second-generation cementation technique and has unacceptably high inter- and intra-observer variability due to its subjective evaluation method. We are introducing a new grading system of quality of femoral cementation. It is based upon the ratio of the length of radiological lucency to the total length of cement-bone interface on both antero-posterior and lateral views. Because of its objective nature, it is likely to show reproducible results. We recruited five observers of various grades of surgical experience (trainees to consultant). Each observer graded the quality of femoral cementation on immediate postop xrays twice (gap of atleast two weeks) of 30 primary hip arthroplasties, using Barrack's grading and a new cementation index measured by dividing the ength of Radiolucency along CBI by the total Length of CBI. Statistical analysis was performed by SPSS v17.0. Inter-observer and Intra-observer variability was determined by Intraclass Correlation Coefficient for a two way mixed model. New cementation index showed excellent agreement for both inter and intra-observer reliability with intraclass correlation coefficient of 0.79 and 0.82 respectively. On contrary, results of inter-observer reliability for Barrack's grading were poor with value of 0.20. intra-observer reliability was found to be fair with 0.55. As evident from this study, it is a more reliable way of assessing the quality of cementation, with excellent agreement in both inter and intra-observer categories

Background. Giant cell tumours of bone (GCT) are benign bone tumours with a locally aggressive character. Local recurrence is considered the main complication of surgical treatment and is described in up to 50% of patients. Intralesional curettage with the use of adjuvants like phenol or polymethylmetacrylate (PMMA) is recommended as initial treatment, significantly decreasing the risk of recurrence. However, risk factors for local recurrence in skeletal GCT have not yet been firmly established and a golden standard for local therapy remains controversial. Objective. The identification of risk factors predisposing for an increased risk of local recurrence. In addition, different surgical techniques are compared to identify the optimal surgical approach for the identified risk factors. Methods. In a retrospective study all 215 patients with bone GCT treated between 1964 and 2009 in one centre were included, of which 193 were suitable for analysis. All patients had minimal follow-up of 12 months (mean 115; range 12–445). Using a Kaplan Meier survival analysis recurrence free survival rates were calculated. Cox-regression was used to determine the influence of different types of therapy, the use of adjuvants, and various patient and tumour characteristics. Results. The mean local recurrence rate for all patients was 35.2% (n=68, 95%CI: 28.3–42.1). Recurrence rate after wide resection was 0.17 (n=6, 95%CI: 0.04–0.29), after curettage with adjuvants 0.32 (n=42, 95%CI 0.24–0.41) and after curettage alone 0.74 (n=20, 95%CI: 0.57–0.91, p < 0.001). Soft tissue extension (Hazard Ratio: 3.8, p < 0.001), localisation in radius and ulna (HR: 2.6, p=0.013), and surgical experience (HR: 2.2, p=0.022) were identified as significant general risk factors for local recurrence. For intralesional resection, Campanacci grade III (HR: 3.9, p=0.019) and location in axial skeleton (HR: 3.3, p=0.016) additionally significantly increased this risk. Comparing treatments our data showed that curettage followed by adjuvants was superior to curettage alone (p < 0.004), and the application of both phenol and PMMA did not present a significantly better outcome than curettage and PMMA alone (HR: 1.07, p=0.881). Conclusion. Of all possible risk factors only soft tissue extension, localisation in radius and ulna and non-radical resections significantly influenced the risk of local recurrence for all treatments. In addition, we found that high-grade tumours and localisation in the axial skeleton were additional risk factors for local recurrence after intralesional surgery. Although wide resection increases patient morbidity, it can be the therapy of choice in high risk patients. Intralesional therapy can be advised for low recurrence risk patients using curettage and PMMA only, whereas our study could not confirm the predicted effect of phenol as an additional adjuvant

Background. For the treatment of proximal humeral fractures two major therapeutic principles can be employed: Intramedullary nailing (PHN) or locking plate osteosynthesis. Aim of this study was to evaluate and compare clinical and radiological long-term outcome of proximal humeral fracture stabilization using PHN or angular stable plating. In addition, we discussed advantages and disadvantages of both techniques and aimed at establishing criteria which operative technique should preferentially be utilized for selected fracture configurations. Materials and Methods. In a prospective study between 2003 and 2010 we analyzed 72 patients with proximal humeral fracture who had been treated by PHN (44 patients) or angular stable plating (28 patients) in a European Level 1 Trauma Center. In the two cohort groups the following epidemiologic data was found. 46 patients were women, and 26 men with a mean age of 60.6 years (range 18–91). Follow-up was performed 38–82 months after accident, on average. Mechanism of injury was fall in 59, motor cycle accident in 4, bike accident in 8 patients, and fall from horse in 1 patient. Duration time between accident and operation was 2.8 days on average. Osteoporosis was previously known in 20 out of all evaluated patients (plate: 7/28; nail: 13/44). Fractures were classified using the Neer classification and Binary description system: There were 35 3-part fractures (PHN: 26; plate: 9) and 37 4-part fractures (PHN: 18; plate: 19), respectively. Functional and radiological outcome was assessed in a range of 38–82 months after trauma using Constant Score. Results. No clinical symptoms after 3 years were observed in 40 patients, whereas in 32 patients clinical symptoms were evaluated related to pain and/or loss of function. Secondary revision after plate fixation had to be performed in 5 out of 28 patients and in 11 out of 44 patients in the PHN group. Functional outcome using the Constant score demonstrated a total score of 72.9 (ipsi-lateral side) vs. 88.4 (contra-lateral side) in all evaluated patients, on average. Complete metal removal was performed in 34 out of 72 patients (PHN: 17; plate: 17). Conclusion. Both i.m. nailing and angular stable plating are adequate treatment options for proximal humeral fractures. No significant differences in outcome between implants regarding fracture healing, nonunion, and infection were found. Locked plating can be utilized for all distal humerus fracture including complex 4-part fractures. I.m. nailing provides favorable intramedullary stability and can be successfully implanted in multi-segmental fractures of the upper extremity. However, both systems require precise preoperative planning and advanced surgical experience. Clinical long-term outcome largely depends on surgical technique and not so much on the choice of implant

Aims

Hospital case volume is shown to be associated with postoperative outcomes in various types of surgery. However, conflicting results of volume-outcome relationship have been reported in hip fracture surgery. This retrospective cohort study aimed to evaluate the association between hospital case volume and postoperative outcomes in patients who had hip fracture surgery. We hypothesized that higher case volume would be associated with lower risk of in-hospital and one-year mortality after hip fracture surgery.

Aims

Surgical site infection can be a devastating complication of hemiarthroplasty of the hip, when performed in elderly patients with a displaced fracture of the femoral neck. It results in a prolonged stay in hospital, a poor outcome and increased costs. Many studies have identified risk and prognostic factors for deep infection. However, most have combined the rates of infection following total hip arthroplasty and internal fixation as well as hemiarthroplasty, despite the fact that they are different entities. The aim of this study was to clarify the risk and prognostic factors causing deep infection after hemiarthroplasty alone.

Unstable pelvic injuries in young children with an immature pelvis have different modes of failure from those in adolescents and adults. We describe the pathoanatomy of unstable pelvic injuries in these children, and the incidence of associated avulsion of the iliac apophysis and fracture of the ipsilateral fifth lumbar transverse process (L5-TP). We retrospectively reviewed the medical records of 33 children with Tile types B and C pelvic injuries admitted between 2007 and 2014; their mean age was 12.6 years (2 to 18) and 12 had an immature pelvis. Those with an immature pelvis commonly sustained symphyseal injuries anteriorly with diastasis, rather than the fractures of the pubic rami seen in adolescents. Posteriorly, transsacral fractures were more commonly encountered in mature children, whereas sacroiliac dislocations and fracture-dislocations were seen in both age groups. Avulsion of the iliac apophysis was identified in eight children, all of whom had an immature pelvis with an intact ipsilateral L5-TP. Young children with an immature pelvis are more susceptible to pubic symphysis and sacroiliac diastasis, whereas bony failures are more common in adolescents. Unstable pelvic injuries in young children are commonly associated with avulsion of the iliac apophysis, particularly with displaced SI joint dislocation and an intact ipsilateral L5-TP.

Prospective data on 6905 consecutive hip fracture patients at a district general hospital were analysed to identify the risk factors for the development of deep infection post-operatively. The main outcome measure was infection beneath the fascia lata.

A total of 50 patients (0.7%) had deep infection. Operations by consultants or a specialist hip fracture surgeon had half the rate of deep infection compared with junior grades (p = 0.01). Increased duration of anaesthesia was significantly associated with deep infection (p = 0.01). The method of fracture fixation was also significant. Intracapsular fractures treated with a hemiarthroplasty had seven times the rate of deep infection compared with those treated by internal fixation (p = 0.001). Extracapsular fractures treated with an extramedullary device had a deep infection rate of 0.78% compared with 0% for those treated with intramedullary devices (p = 0.02).

The management of hip fracture patients by a specialist hip fracture surgeon using appropriate fixation could significantly reduce the rate of deep infection and associated morbidity, along with extended hospitalisation and associated costs.

A high rate of complications is associated with open reduction and internal fixation of Sanders type 4 fractures of the calcaneum. We assessed the long-term outcome of 83 Sanders type 4 comminuted intra-articular fractures of the calcaneum in 64 patients who underwent non-operative treatment between 1999 and 2005. Each fracture was treated by closed reduction and immobilisation in a long leg cast. Patients were reviewed every three months in the first year, and every six months thereafter. At each visit, the involved ankles were assessed by the American Orthopaedic Foot and Ankle Society (AOFAS) criteria. The degree of fracture healing and the presence of osteoarthritis were assessed.

At a mean follow-up of 51 months (24 to 70) the mean AOFAS score was 72 (52 to 92). Osteoarthritis was scored radiologically using Graves’ classification and was evident in the subtalar joints of 75 ankles (90%) on x-ray and in all ankles on CT scans, of which 20 were grade 0 or 1, 39 grade 2, and 24 grade 3.

A non-operative approach to treating these fractures may be simpler, less expensive, easier to administer with fewer complications, and may be better tolerated than surgery, by many patients.

Crescent fracture dislocations are a well-recognised subset of pelvic ring injuries which result from a lateral compression force. They are characterised by disruption of the sacroiliac joint and extend proximally as a fracture of the posterior iliac wing. We describe a classification with three distinct types. Type I is characterised by a large crescent fragment and the dislocation comprises no more than one-third of the sacroiliac joint, which is typically inferior. Type II fractures are associated with an intermediate-size crescent fragment and the dislocation comprises between one- and two-thirds of the joint. Type III fractures are associated with a small crescent fragment where the dislocation comprises most, but not all of the joint. The principal goals of surgical intervention are the accurate and stable reduction of the sacroiliac joint. This classification proves useful in the selection of both the surgical approach and the reduction technique. A total of 16 patients were managed according to this classification and achieved good functional results approximately two years from the time of the index injury. Confounding factors compromise the summary short-form-36 and musculoskeletal functional assessment instrument scores, which is a well-recognised phenomenon when reporting the outcome of high-energy trauma.
