The augmentation of fixation with bone cement
is increasingly being used in the treatment of severe osteoporotic fractures.
We investigated the influence of bone quality on the mechanics of
augmentation of plate fixation in a distal femoral fracture model
(AO 33 A3 type). Eight osteoporotic and eight non-osteoporotic femoral
models were randomly assigned to either an augmented or a non-augmented
group. Fixation was performed using a locking compression plate.
In the augmented group additionally 1 ml of bone cement was injected
into the screw hole before insertion of the screw. Biomechanical
testing was performed in axial sinusoidal loading. Augmentation significantly
reduced the cut-out distance in the osteoporotic models by about
67% (non-augmented mean 0.30 mm ( Cite this article:
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. This was a multicentre retrospective cohort study including adult patients who presented to 27 NHS hospitals with 539 new PPFs between 1 January 2018 and 31 December 2018. Data collected included: management strategy (operative and nonoperative), length of stay, discharge destination, and details of post-treatment outcomes (reoperation, readmission, and 30-day and 12-month mortality). Descriptive analysis by fracture type was performed, and predictors of PPF management and outcomes were assessed using mixed-effects logistic regression.Aims
Methods
Despite limited clinical scientific backing, an additional trochanteric stabilizing plate (TSP) has been advocated when treating unstable trochanteric fractures with a sliding hip screw (SHS). We aimed to explore whether the TSP would result in less post operative fracture motion, compared to SHS alone. Overall, 31 patients with AO/OTA 31-A2 trochanteric fractures were randomized to either a SHS alone or a SHS with an additional TSP. To compare postoperative fracture motion, radiostereometric analysis (RSA) was performed before and after weightbearing, and then at four, eight, 12, 26, and 52 weeks. With the “after weightbearing” images as baseline, we calculated translations and rotations, including shortening and medialization of the femoral shaft.Aims
Methods
The aim of this study was to evaluate the clinical and radiological outcomes of locking plate fixation, with and without an associated fibular strut allograft, for the treatment of displaced proximal humeral fractures in elderly osteoporotic patients. We undertook a retrospective comparison of two methods of fixation, using a locking plate without an associated fibular strut allograft (LP group) and with a fibular allograft (FA group) for the treatment of these fractures. The outcome was assessed for 52 patients in the LP group and 45 in the FA group, with a mean age of 74.3 years (52 to 89), at a mean follow-up of 14.2 months (12 to 19). The clinical results were evaluated using a visual analogue scale (VAS) score for pain, the Constant score, the American Shoulder and Elbow Surgeons (ASES) score, and the range of movement. Radiological results were evaluated using the neck-shaft angle (NSA) and humeral head height (HHH).Aims
Patients and Methods
Fractures of the distal femur can be challenging to manage and
are on the increase in the elderly osteoporotic population. Management
with casting or bracing can unacceptably limit a patient’s ability
to bear weight, but historically, operative fixation has been associated
with a high rate of re-operation. In this study, we describe the outcomes
of fixation using modern implants within a strategy of early return
to function. All patients treated at our centre with lateral distal femoral
locking plates (LDFLP) between 2009 and 2014 were identified. Fracture
classification and operative information including weight-bearing
status, rates of union, re-operation, failure of implants and mortality
rate, were recorded.Aims
Patients and Methods
The aim of this study was to quantify the stability
of fracture-implant complex in fractures after fixation. A total
of 15 patients with an undisplaced fracture of the femoral neck,
treated with either a dynamic hip screw or three cannulated hip
screws, and 16 patients with an AO31-A2 trochanteric fracture treated
with a dynamic hip screw or a Gamma Nail, were included. Radiostereometric
analysis was used at six weeks, four months and 12 months post-operatively
to evaluate shortening and rotation. Migration could be assessed in ten patients with a fracture of
the femoral neck and seven with a trochanteric fracture. By four
months post-operatively, a mean shortening of 5.4 mm (-0.04 to 16.1)
had occurred in the fracture of the femoral neck group and 5.0 mm
(-0.13 to 12.9) in the trochanteric fracture group. A wide range
of rotation occurred in both types of fracture. Right-sided trochanteric
fractures seem more rotationally stable than left-sided fractures. This prospective study shows that migration at the fracture site
occurs continuously during the first four post-operative months,
after which stabilisation occurs. This information may allow the
early recognition of patients at risk of failure of fixation. Cite this article:
