The prevalence of ipsilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA) is rising in concert with life expectancy, putting more patients at risk for interprosthetic femur fractures (IPFFs). Our study aimed to assess treatment methodologies, implant survivorship, and IPFF clinical outcomes. A total of 76 patients treated for an IPFF from February 1985 to April 2018 were reviewed. Prior to fracture, at the hip/knee sites respectively, 46 femora had primary/primary, 21 had revision/primary, three had primary/revision, and six had revision/revision components. Mean age and BMI were 74 years (33 to 99) and 30 kg/m2 (21 to 46), respectively. Mean follow-up after fracture treatment was seven years (2 to 24).Aims
Methods
The objective of this study was to investigate bone healing after
internal fixation of displaced femoral neck fractures (FNFs) with
the Dynamic Locking Blade Plate (DLBP) in a young patient population
treated by various orthopaedic (trauma) surgeons. We present a multicentre prospective case series with a follow-up
of one year. All patients aged ≤ 60 years with a displaced FNF treated
with the DLBP between 1st August 2010 and December 2014 were included.
Patients with pathological fractures, concomitant fractures of the
lower limb, symptomatic arthritis, local infection or inflammation,
inadequate local tissue coverage, or any mental or neuromuscular
disorder were excluded. Primary outcome measure was failure in fracture
healing due to nonunion, avascular necrosis, or implant failure
requiring revision surgery.Aims
Patients and Methods
Advocates of debridement, antibiotics and implant retention (DAIR)
in hip periprosthetic joint infection (PJI) argue that a procedure
not disturbing a sound prosthesis-bone interface is likely to lead
to better survival and functional outcome compared with revision.
This case-control study aims were to compare outcome of DAIRs for
infected primary total hip arthroplasty (THA) with outcomes following
primary THA and two-stage revision of infected primary THAs. We retrospectively reviewed all DAIRs, performed for confirmed
infected primary hip arthropasty (n = 82) at out institution, between
1997 and 2013. Data recorded included full patient information and
type of surgery. Outcome measures included complications, mortality,
implant survivorship and functional outcome. Outcome was compared with
two control groups matched for gender and age; a cohort of primary
THAs (n = 120) and a cohort of two-stage revisions for infection
(n = 66).Aims
Patients and Methods
In order to prevent dislocation of the hip after total hip arthroplasty
(THA), patients have to adhere to precautions in the early post-operative
period. The hypothesis of this study was that a protocol with minimal
precautions after primary THA using the posterolateral approach
would not increase the short-term (less than three months) risk
of dislocation. We prospectively monitored a group of unselected patients undergoing
primary THA managed with standard precautions (n = 109, median age
68.9 years; interquartile range (IQR) 61.2 to 77.3) and a group
who were managed with fewer precautions (n = 108, median age 67.2
years; IQR 59.8 to 73.2). There were no significant differences between
the groups in relation to predisposing risk factors. The diameter
of the femoral head ranged from 28 mm to 36 mm; meticulous soft-tissue
repair was undertaken in all patients. The medical records were
reviewed and all patients were contacted three months post-operatively
to confirm whether they had experienced a dislocation. Aims
Patients and Methods
Tapered, fluted, modular, titanium stems are
increasingly popular in the operative management of Vancouver B2 and
selected B3 peri-prosthetic femoral fractures. We have reviewed
the results at our institution looking at stem survival and clinical
outcomes and compared this with reported outcomes in the literature.
Stem survival at a mean of 54 months was 96% in our series and 97%
for combined published cases. Review of radiology showed maintenance
or improvement of bone stock in 89% of cases with high rates of
femoral union. Favourable clinical outcome scores have reported
by several authors. No difference in survival or clinical scores
was observed between B2 and B3 fractures. Tapered stems are a useful
option in revision for femoral fracture across the spectrum of femoral
bone deficiency. Cite this article:
We report the outcome of 39 patients who underwent
a modified Pauwels’ intertrochanteric osteotomy for nonunion of
a femoral neck fracture following failed osteosynthesis. There were
31 men and eight women with a mean age of 47.2 years (34 to 59).
By Pauwels’ classification, there were 11 Type II fractures and
28 Type III fractures. The mean follow-up was 7.9 years (2 to 19).
In the 11 patients whose initial treatment had been osteotomy, union was
achieved in nine (81.8%). In 28 patients whose initial treatment
had been with a lag screw or a dynamic hip screw, union was achieved
in 27 (96.4%). Limb lengths were equalised in 14 of 16 patients
(87.5%) with pre-operative shortening. The mean neck-shaft angle
improved significantly from 100.5° (80° to 120°) to 131.6° (120°
to 155°) (p = 0.004). The mean modified Harris hip score was 85.6
points (70 to 97) and the mean modified Merle d’Aubigné score was
14.3 (11 to 18). Good to excellent functional outcomes were achieved
in 32 patients (88.8%). A modified Pauwels’ intertrochanteric osteotomy
is a reliable method of treating ununited fractures of the femoral neck
following failed osteosynthesis: coxa vara and shortening can also
simultaneously be addressed. Cite this article
We undertook a multicentre, prospective study of a series of 112 unstable trochanteric fractures in order to evaluate if internal fixation with a sliding screw device combined with augmentation using a calcium phosphate degradable cement (Norian SRS) could improve the clinical, functional and radiological outcome when compared with fractures treated with a sliding screw device alone. Pain, activities of daily living, health status (SF-36), the strength of the hip abductor muscles and radiological outcome were analysed. Six weeks after surgery, the patients in the augmented group had significantly lower global and functional pain scores (p <
0.003), less pain after walking 50 feet (p <
0.01), and a better return to the activities of daily living (p <
0.05). At follow-up at six weeks and six months, those in the augmented group showed a significant improvement compared with the control group in the SF-36 score. No other significant differences were found between the groups. We conclude that augmentation with calcium phosphate cement in unstable trochanteric fractures provides a modest reduction in pain and a slight improvement in the quality of life during the course of healing when compared with conventional fixation with a sliding screw device alone.
