We report the functional and socioeconomic long-term
outcome of patients with pelvic ring injuries. We identified 109 patients treated at a Level I trauma centre
between 1973 and 1990 with multiple blunt orthopaedic injuries including
an injury to the pelvic ring, with an Injury Severity Score (ISS)
of ≥ 16. These patients were invited for clinical review at a minimum
of ten years after the initial injury, at which point functional
results, general health scores and socioeconomic factors were assessed. In all 33 isolated anterior (group A), 33 isolated posterior
(group P) and 43 combined anterior/posterior pelvic ring injuries
(group A/P) were included. The mean age of the patients at injury
was 28.8 years (5 to 55) and the mean ISS was 22.7 (16 to 44). At review the mean Short-Form 12 physical component score for
the A/P group was 38.71 (22.12 to 56.56) and the mean Hannover Score
for Polytrauma Outcome subjective score was 67.27 (12.48 to 147.42),
being significantly worse compared with the other two groups (p =
0.004 and p = 0.024, respectively). A total of 42 patients (39%)
had a limp and 12 (11%) required crutches. Car or public transport
usage was restricted in 16 patients (15%). Overall patients in groups
P and A/P had a worse outcome. The long-term outcome of patients
with posterior or combined anterior/posterior pelvic ring injuries
is poorer than of those with an isolated anterior injury. Cite this article:
A wide variety of intra- and extramedullary devices for the treatment of trochanteric fractures has been described. The Percutaneous Compression Plate is a minimally invasive and extramedullary device, which requires two 2–2.5 cm long incisions with minimal dissection oft soft tissue on the lateral aspect of the proximal femur. Earlier studies indicated that internal fixation using the PCCP is associated with a decreased perioperative blood loss, reduced transfusion requirements, with less postoperative pain, more rapid mobilisation, and with a reduced incidence of collapse of the fracture when compared with the standard device Dynamic Hip Screw. Aim of this study is to analyze the risk factors for the occurrence of local complications after internal fixation of intertrochanteric fractures of the femur using a Percutaneous Compression Plate. In a retrospective cohort study patients with trochanteric fractures who underwent internal fixation with a PCCP were included. We investigated the potential risk factors age, gender, experience of the surgeon as indicated by the numbers of surgical procedures with the PCCP device, stability of the fracture according to the AO/OTA classification, and co-morbidities of the patients according to the ASA classification. The operations were performed by ten different surgeons. All local complications which required re-operation were recorded. They included cutting out of the screw, loosening of the screw barrels, local haematoma, and infections. Logistic regression analysis was carried out to determine the risk factors for local complications. The mean age of the 122 patients included in this study was 78.5 years. 87 patients were female (70.7 %), 36 patients were male (29.3 %). With respect to the stability of the fracture 64 trochanteric fractures (52.5%) were classified as stable according to the AO/OTA classification, whereas 58 (47.5%) were considered to be unstable. Of the total of 122 patients with 122 trochanteric fractures eleven underwent re-operation due to local complications (9 %). The most frequent complication was complete or imminent cutting out of the upper cervical screw (N=5; 4 %). In the multivariate logistic regression model the only statistically significant risk factor was the experience of the surgeon (p=0.0316; odds ratio=4.7; CI 1.1–19.4). Our data indicate that the experience of the surgeon is a significant risk factor for the occurrence of local complications. The frequent use of this device seems to lower the re-operation rate.
Unstable intertrochanteric hip fractures (AO 31A2) continue to be a challenge, as non-locking implants have shown a considerable rate of loss of reduction. Intramedullary fixation has been recommended, although screw cut-out has been identified as problematic. This study was performed to ascertain whether treatments with the established proximal femoral nail (PFN) and the newer PFNA with blade design (proximal femoral nail antirotation) have advantages over the use of the Percutaneous Compression Plate (PCCP, developed by Gotfried). Cohort study. Between March 2003 and March 2008, 134 patients with unstable fractures were treated with a PCCP, (n=44, 78.3 yrs, ASA 2.8), a PFN (n=50, 77.2 yrs, ASA 2.8), or a PFNA (n=40, 75.8 yrs, ASA 2.6). The patients (31 PCCP, 33 PFN, 30 PFNA) were then reexamined clinically and radiologically after approximately 21 months.Introduction
Methods
The additive use of an external modular device may improve dorsal compression forces in pelvic external fixation. This would improve the efficiency of indirect reduction and stabilization with an anterior pelvic external fixator. The purpose of this study was to determine the forces of the posterior pelvis achieved by a new device improving the application of a supraacetabular anterior external fixator compared with other constructs. Synthetic pelvic models were used. Complete pelvic ring instability was created by symphyseal and unilateral sacroiliac joint disruption. Four different constructs of fixation were tested. A pressure-sensitive film was placed in the sacroiliac joint. The constructs were applied in a standardized way. The maximum sacroiliacal compression loads (N) of each trial was recorded. Statistics was performed with the student t-test.Objectives
Material and Method
Patients with bilateral femur fractures are known to be at a high risk for the Systemic Inflammatory Response Syndrome; however the impact of fracture-associated soft tissue injury in the induction of systemic inflammation following bilateral femur fracture is poorly understood. To address this, the systemic inflammatory response and remote organ dysfunction following bilateral femur fracture with various degrees of soft tissue injuries were investigated in this study. 6–8 weeks old male C57/BL6 mice (n = 4–8 animals per group) were grouped as follows: Control-group (no anaesthesia, no femoral catheterisation); Sham-group (6 hour anaesthesia, femoral catheterisation); Fx-group (6 hour anaesthesia, femoral catheterisation, bilateral femur fracture with minor soft tissue injury); Fx+STI-group (6 hour anaesthesia, femoral catheterisation, bilateral femur fracture with severe soft tissue injury). Six hours after bilateral femur fracture serum levels of IL-2, IL-4, IL-6, IL-10, IL-12, TNF-α, KC and MCP-1 were measured. Furthermore, IL-6 levels of homogenized liver tissue were assessed. Neutrophil accumulation in liver and lung was determined with a myeloperoxidase (MPO) assay. Changes in liver permeability were assessed by measuring the wet-dry-ratio. The Fx+STI-group showed significantly increased serum cytokine levels as compared to the Fx- or Sham-group. The homogenized liver tissue of the Fx+STI-group showed significantly increased IL-6 levels as compared to the Sham-group. The MPO activity in lung and liver in the Fx+STI-group was significantly increased in comparison to the Fx- or Sham-group and in the Fx-group in comparison to the Sham-group. The wet-dry-ratio of the liver was significantly increased in the Fx+STI-group as compared to the Sham-group. The degree of fracture-associated soft tissue injury appears to modify systemic inflammation following bilateral femur fracture and is able to induce remote organ dysfunction. These results may have implications that have been underestimated, thus warranting clinical follow-up studies.
