Exsanguination is the second most common cause
of death in patients who suffer severe trauma. The management of
haemodynamically unstable high-energy pelvic injuries remains controversial,
as there are no universally accepted guidelines to direct surgeons
on the ideal use of pelvic packing or early angio-embolisation.
Additionally, the optimal resuscitation strategy, which prevents
or halts the progression of the trauma-induced coagulopathy, remains
unknown. Although early and aggressive use of blood products in
these patients appears to improve survival, over-enthusiastic resuscitative
measures may not be the safest strategy. This paper provides an overview of the classification of pelvic
injuries and the current evidence on best-practice management of
high-energy pelvic fractures, including resuscitation, transfusion
of blood components, monitoring of coagulopathy, and procedural
interventions including pre-peritoneal pelvic packing, external
fixation and angiographic embolisation. Cite this article:
Tibial nonunion represents a spectrum of conditions
which are challenging to treat, and optimal management remains unclear
despite its high rate of incidence. We present 44 consecutive patients
with 46 stiff tibial nonunions, treated with hexapod external fixators
and distraction to achieve union and gradual deformity correction.
There were 31 men and 13 women with a mean age of 35 years (18 to
68) and a mean follow-up of 12 months (6 to 40). No tibial osteotomies
or bone graft procedures were performed. Bony union was achieved
after the initial surgery in 41 (89.1%) tibias. Four persistent
nonunions united after repeat treatment with closed hexapod distraction,
resulting in bony union in 45 (97.8%) patients. The mean time to
union was 23 weeks (11 to 49). Leg-length was restored to within
1 cm of the contralateral side in all tibias. Mechanical alignment
was restored to within 5° of normal in 42 (91.3%) tibias. Closed
distraction of stiff tibial nonunions can predictably lead to union
without further surgery or bone graft. In addition to generating
the required distraction to achieve union, hexapod circular external
fixators can accurately correct concurrent deformities and limb-length
discrepancies. Cite this article:
In this paper, we critically appraise the recent
publication of the United Kingdom Heel Fracture Trial, which concluded
that when patients with an absolute indication for surgery were
excluded, there was no advantage of surgical over non-surgical treatment
in the management of calcaneal fractures. We believe that selection bias in that study did not permit the
authors to reach a firm conclusion that surgery was not justified
for most intra-articular calcaneal fractures. Cite this article:
In this retrospective cohort study, we analysed
the incidence and functional outcome of a distal tibiofibular synostosis.
Patients with an isolated AO type 44-B or C fracture of the ankle
who underwent surgical treatment between 1995 and 2007 were invited
for clinical and radiological review. The American Orthopaedic Foot
and Ankle Society score, the American Academy of Orthopaedic Surgeons
score and a visual analogue score for pain were used to assess outcome. A total of 274 patients were available; the mean follow-up was
9.7 years (8 to 18). The extent of any calcification or synostosis
at the level of the distal interosseous membrane or syndesmosis
on the contemporary radiographs was defined as: no or minor calcifications
(group 1), severe calcification (group 2), or complete synostosis
(group 3). A total of 222 (81%) patients were in group 1, 37 (14%) in group
2 and 15 (5%) in group 3. There was no significant difference in
incidence between AO type 44-B and type 44-C fractures (p = 0.89).
Severe calcification or synostosis occurred in 21 patients (19%)
in whom a syndesmotic screw was used and in 31 (19%) in whom a syndesmotic screw
was not used.(p = 0.70). No significant differences were found between
the groups except for a greater reduction in mean dorsiflexion in
group 2 (p = 0.004). This is the largest study on distal tibiofibular synostosis,
and we found that a synostosis is a frequent complication of surgery
for a fracture of the ankle. Although it theoretically impairs the
range of movement of the ankle, it did not affect the outcome. Our findings suggest that synostosis of the distal tibiofibular
syndesmosis in general does not warrant treatment. Cite this article:
This retrospective cohort study was conducted to investigate whether operative treatment of patients with a pertrochanteric femoral fracture outside working hours is associated with an increased risk of complications and higher mortality. During the study period 165 patients were operated on outside working hours and 123 were operated on during working hours (08.00 to 17.00). There was no difference in the rate of early complications (outside working hours 33% versus working hours 33%, p = 0.91) or total complications during follow-up (outside working hours 40% versus working hours 41%, p = 0.91). Both in-hospital mortality (outside working hours 12% versus working hours 11%, p = 0.97) and mortality after one year (outside working hours 29% versus working hours 27%, p = 0.67) were comparable. Adjustment for possible confounders by multivariate logistic regression analysis revealed no increased risk of complications when patients were operated on outside working hours. On the basis of these data, there is no medical reason to postpone operative reduction and fixation in patients with a proximal femoral fracture until working hours.

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:

The purpose of this study was to describe the
radiological characteristics of a previously unreported finding: posterior
iliac offset at the sacroiliac joint and to assess its association
with pelvic instability as measured by initial displacement and
early implant loosening or failure. Radiographs from 42 consecutive
patients with a mean age of 42 years (18 to 77; 38 men, four women)
and mean follow-up of 38 months (3 to 96) with Anteroposterior Compression
II injuries, were retrospectively reviewed. Standardised measurements
were recorded for the extent of any diastasis of the pubic symphysis,
widening of the sacroiliac joint, static vertical ramus offset and
a novel measurement (posterior offset of the ilium at the sacroiliac
joint identified on axial CT scan). Pelvic fractures with posterior
iliac offset exhibited greater levels of initial displacement of
the anterior pelvis (anterior sacroiliac widening, pubic symphysis
diastasis and static vertical ramus offset, p <
0.001,0.034 and
0.028, respectively). Pelvic fractures with posterior ilium offset
also demonstrated higher rates of implant loosening regardless of
fixation method (p = 0.05). Posterior offset of the ilium was found
to be a reliable and reproducible measurement with substantial inter-observer
agreement (kappa = 0.70). Posterior offset of the ilium on axial
CT scan is associated with greater levels of initial pelvic displacement
and early implant loosening. Cite this article:

While the demand for orthopaedic surgical expertise in the developing world is in critically short supply, short-term remedy from visiting doctors cannot solve this long-term healthcare problem. Capacity building by senior and training orthopaedic surgeons from established Western training programmes can offer a significant contribution to the orthopaedic patient in the developing world and the gains for those visiting are extremely valuable. We report on several visits by a UK orthopaedic team to a hospital in Kabul, Afghanistan and discuss the operative and non-operative case mix and the benefits in terms of local capacity building and the unique experience of those visiting.

We compared a new fixation system, the Targon
Femoral Neck (TFN) hip screw, with the current standard treatment of
cannulated screw fixation. This was a single-centre, participant-blinded,
randomised controlled trial. Patients aged 65 years and over with
either a displaced or undisplaced intracapsular fracture of the
hip were eligible. The primary outcome was the risk of revision
surgery within one year of fixation. A total of 174 participants were included in the trial. The absolute
reduction in risk of revision was of 4.7% (95% CI 14.2 to 22.5)
in favour of the TFN hip screw (chi-squared test, p = 0.741), which
was less than the pre-specified level of minimum clinically important
difference. There were no significant differences in any of the
secondary outcome measures. We found no evidence of a clinical difference in the risk of
revision surgery between the TFN hip screw and cannulated screw
fixation for patients with an intracapsular fracture of the hip. Cite this article:
