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
To evaluate if, for orthopaedic trainees, additional cadaveric simulation training or standard training alone yields superior radiological and clinical outcomes in patients undergoing dynamic hip screw (DHS) fixation or hemiarthroplasty for hip fracture. This was a preliminary, pragmatic, multicentre, parallel group randomized controlled trial in nine secondary and tertiary NHS hospitals in England. Researchers were blinded to group allocation. Overall, 40 trainees in the West Midlands were eligible: 33 agreed to take part and were randomized, five withdrew after randomization, 13 were allocated cadaveric training, and 15 were allocated standard training. The intervention was an additional two-day cadaveric simulation course. The control group received standard on-the-job training. Primary outcome was implant position on the postoperative radiograph: tip-apex distance (mm) (DHS) and leg length discrepancy (mm) (hemiarthroplasty). Secondary clinical outcomes were procedure time, length of hospital stay, acute postoperative complication rate, and 12-month mortality. Procedure-specific secondary outcomes were intraoperative radiation dose (for DHS) and postoperative blood transfusion requirement (hemiarthroplasty).Aims

Postoperative malalignment of the femur is one of the main complications in distal femur fractures. Few papers have investigated the impact of intraoperative malalignment on postoperative function and bone healing outcomes. The aim of this study was to investigate how intraoperative fracture malalignment affects postoperative bone healing and functional outcomes. In total, 140 patients were retrospectively identified from data obtained from a database of hospitals participating in a trauma research group. We divided them into two groups according to coronal plane malalignment of more than 5°: 108 had satisfactory fracture alignment (< 5°, group S), and 32 had unsatisfactory alignment (> 5°, group U). Patient characteristics and injury-related factors were recorded. We compared the rates of nonunion, implant failure, and reoperation as healing outcomes and Knee Society Score (KSS) at three, six, and 12 months as functional outcomes. We also performed a sub-analysis to assess the effect of fracture malalignment by plates and nails on postoperative outcomes.Aims
Methods
No randomized comparative study has compared the extensile lateral approach (ELA) and sinus tarsi approach (STA) for Sanders type 2 calcaneal fractures. This randomized comparative study was conducted to confirm whether the STA was prone to fewer wound complications than the ELA. Between August 2013 and August 2018, 64 patients with Sanders type 2 calcaneus fractures were randomly assigned to receive surgical treatment by the ELA (32 patients) and STA (32 patients). The primary outcome was development of wound complications. The secondary outcomes were postoperative complications, pain scored of a visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, 36-item Short Form health survey, operative duration, subtalar joint range of motion (ROM), Böhler’s angle and calcaneal width, and posterior facet reduction.Aims
Methods
A lack of supporting clinical studies have been published to determine the ideal length of intramedullary nail in fixation of trochanteric fractures of the hip. Nevertheless, there has been a trend to use shorter intramedullary nails for the internal fixation of trochanteric hip fractures. Our aim was to determine if the length of nail affected the outcome. We randomized 229 patients with a trochanteric hip fracture between two implants: a ‘standard’ nail of 220 mm and a shorter nail of 175 mm, which had decreased proximal angulation (4° vs 7°) and a reduced diameter at the level of the lesser trochanter. Patients were followed up for one year by a nurse blinded to the type of implant used to determine if there were differences in mobility and pain with two nail designs. Pain was assessed on a scale of 1 (none) to 8 (severe and constant) and mobility on a scale of 1 (full mobility) to 9 (immobile).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
The aim of this study was to evaluate the outcomes of a salvage procedure using a 95° angled blade plate for failed osteosynthesis of atypical subtrochanteric femoral fractures associated with the long-term use of bisphosphonates. These were compared with those for failed osteosynthesis of subtrochanteric fractures not associated with bisphosphonate treatment. Between October 2008 and July 2016, 14 patients with failed osteosynthesis of an atypical subtrochanteric femoral fracture were treated with a blade plate (atypical group). Their mean age was 67.8 years (60 to 74); all were female. During the same period, 21 patients with failed osteosynthesis of a typical subtrochanteric fracture underwent restabilization using a blade plate (typical group). Outcome variables included the time of union, postoperative complications, Harris Hip Score, and Sanders functional rating scale.Aims
Patients and Methods
The aim of this paper is to review the evidence relating to the
anatomy of the proximal femur, the geometry of the fracture and
the characteristics of implants and methods of fixation of intertrochanteric
fractures of the hip. Relevant papers were identified from appropriate clinical databases
and a narrative review was undertaken.Aims
Materials and Methods
Accurate characterisation of fractures is essential in fracture management trials. However, this is often hampered by poor inter-observer agreement. This article describes the practicalities of defining the fracture population, based on the Neer classification, within a pragmatic multicentre randomised controlled trial in which surgical treatment was compared with non-surgical treatment in adults with displaced fractures of the proximal humerus involving the surgical neck. The trial manual illustrated the Neer classification of proximal humeral fractures. However, in addition to surgical neck displacement, surgeons assessing patient eligibility reported on whether either or both of the tuberosities were involved. Anonymised electronic versions of baseline radiographs were sought for all 250 trial participants. A protocol, data collection tool and training presentation were developed and tested in a pilot study. These were then used in a formal assessment and classification of the trial fractures by two independent senior orthopaedic shoulder trauma surgeons.Objectives
Methods
Fractures of the distal femur are an important cause of morbidity.
Their optimal management remains controversial. Contemporary implants
include angular-stable anatomical locking plates and locked intramedullary
nails (IMNs). We compared the long-term patient-reported functional
outcome of fixation of fractures of the distal femur using these
two methods of treatment. A total of 297 patients were retrospectively identified from
a State-wide trauma registry in Australia: 195 had been treated
with a locking plate and 102 with an IMN. Baseline characteristics
of the patients and their fractures were recorded. Health-related
quality-of-life, functional and radiographic outcomes were compared
using mixed effects regression models at six months and one year.Aims
Patients and Methods
This study aimed to determine the long-term functional,
clinical and radiological outcomes in patients with Schatzker IV
to VI fractures of the tibial plateau treated with an Ilizarov frame.
Clinical, functional and radiological assessment was carried out
at a minimum of one year post-operatively. A cohort of 105 patients
(62 men, 43 women) with a mean age of 49 years (15 to 87) and a
mean follow-up of 7.8 years (1 to 19) were reviewed. There were
18 type IV, 10 type V and 77 type VI fractures. All fractures united
with a mean time to union of 20.1 weeks (10.6 to 42.3). No patient
developed a deep infection. The median range of movement (ROM) of
the knee was 110o and the median Iowa score was 85. Our study demonstrates good long-term functional outcome with
no deep infection; spanning the knee had no detrimental effect on
the ROM or functional outcome. High-energy fractures of the tibial plateau may be treated effectively
with a fine wire Ilizarov fixator. 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:
We prospectively assessed the diagnostic accuracy
of the gravity stress test and clinical findings to evaluate the stability
of the ankle mortise in patients with supination–external rotation-type
fractures of the lateral malleolus without widening of the medial
clear space. The cohort included 79 patients with a mean age of
44 years (16 to 82). Two surgeons assessed medial tenderness, swelling
and ecchymosis and performed the external rotation (ER) stress test
(a reference standard). A diagnostic radiographer performed the
gravity stress test. For the gravity stress test, the positive likelihood ratio (LR)
was 5.80 with a 95% confidence interval (CI) of 2.75 to 12.27, and
the negative LR was 0.15 (95% CI 0.07 to 0.35), suggesting a moderate
change from the pre-test probability. Medial tenderness, both alone
and in combination with swelling and/or ecchymosis, indicated a
small change (positive LR, 2.74 to 3.25; negative LR, 0.38 to 0.47),
whereas swelling and ecchymosis indicated only minimal changes (positive
LR, 1.41 to 1.65; negative LR, 0.38 to 0.47). In conclusion, when gravity stress test results are in agreement
with clinical findings, the result is likely to predict stability
of the ankle mortise with an accuracy equivalent to ER stress test
results. When clinical examination suggests a medial-side injury,
however, the gravity stress test may give a false negative result. Cite this article:
This study compares the outcomes of two methods
of fixation of displaced fractures of the radial neck. The 58 patients
with a mean age of 38.5 years (18 to 56), were treated in a non
randomised study with screws (n = 29) or a plate and screws (n =
29) according to the surgeon’s preference. The patients were reviewed at one year. Radiographs and functional
evaluations were carried out up to one year post-operatively, using
the Broberg and Morrey functional evaluation score, range of movement,
and assessment of complications. The mean functional scores did not differ significantly between
groups (90 (55 to 100) Cite this article:
Radiological evidence of post-traumatic osteoarthritis
(PTOA) after fracture of the tibial plateau is common but end-stage arthritis
which requires total knee arthroplasty is much rarer. The aim of this study was to examine the indications for, and
outcomes of, total knee arthroplasty after fracture of the tibial
plateau and to compare this with an age and gender-matched cohort
of TKAs carried out for primary osteoarthritis. Between 1997 and 2011, 31 consecutive patients (23 women, eight
men) with a mean age of 65 years (40 to 89) underwent TKA at a mean
of 24 months (2 to 124) after a fracture of the tibial plateau.
Of these, 24 had undergone ORIF and seven had been treated non-operatively.
Patients were assessed pre-operatively and at 6, 12 and >
60 months
using the Short Form-12, Oxford Knee Score and a patient satisfaction
score. Patients with instability or nonunion needed total knee arthroplasty
earlier (14 and 13.3 months post-injury) than those with intra-articular
malunion (50 months, p <
0.001). Primary cruciate-retaining implants
were used in 27 (87%) patients. Complication rates were higher in
the PTOA cohort and included wound complications (13% Total knee arthroplasty undertaken after fracture of the tibial
plateau has a higher rate of complications than that undertaken
for primary osteoarthritis, but patient-reported outcomes and satisfaction
are comparable. Cite this article:
Conventional methods of treating ankle fractures
in the elderly are associated with high rates of complication. We describe
the results of treating these injuries in 48 frail elderly patients
with a long calcaneotalotibial nail. The mean age of the group was 82 years (61 to 96) and 41 (85%)
were women. All were frail, with multiple medical comorbidities
and their mean American Society of Anaesthesiologists score was
3 (3 to 4). None could walk independently before their operation.
All the fractures were displaced and unstable; the majority (94%,
45 of 48) were low-energy injuries and 40% (19 of 48) were open. . The overall mortality at six months was 35%. Of the surviving
patients, 90% returned to their pre-injury level of function. The
mean pre- and post-operative Olerud and Molander questionnaire scores
were 62 and 57 respectively. Complications included superficial
infection (4%, two of 48); deep infection (2%, one of 48); a broken
or loose distal locking screw (6%, three of 48);
Coronal plane fractures of the posterior femoral
condyle, also known as Hoffa fractures, are rare. Lateral fractures are
three times more common than medial fractures, although the reason
for this is not clear. The exact mechanism of injury is likely to
be a vertical shear force on the posterior femoral condyle with
varying degrees of knee flexion. These fractures are commonly associated
with high-energy trauma and are a diagnostic and surgical challenge. Hoffa
fractures are often associated with inter- or supracondylar distal
femoral fractures and CT scans are useful in delineating the coronal
shear component, which can easily be missed. There are few recommendations
in the literature regarding the surgical approach and methods of
fixation that may be used for this injury. Non-operative treatment
has been associated with poor outcomes. The goals of treatment are
anatomical reduction of the articular surface with rigid, stable
fixation to allow early mobilisation in order to restore function.
A surgical approach that allows access to the posterior aspect of
the femoral condyle is described and the use of postero-anterior
lag screws with or without an additional buttress plate for fixation
of these difficult fractures. Cite this article:
Most fractures of the radial head are stable
undisplaced or minimally displaced partial fractures without an associated
fracture of the elbow or forearm or ligament injury, where stiffness
following non-operative management is the primary concern. Displaced
unstable fractures of the radial head are usually associated with other
fractures or ligament injuries, and restoration of radiocapitellar
contact by reconstruction or prosthetic replacement of the fractured
head is necessary to prevent subluxation or dislocation of the elbow
and forearm. In fractures with three or fewer fragments (two articular
fragments and the neck) and little or no metaphyseal comminution,
open reduction and internal fixation may give good results. However,
fragmented unstable fractures of the radial head are prone to early
failure of fixation and nonunion when fixed. Excision of the radial
head is associated with good long-term results, but in patients
with instability of the elbow or forearm, prosthetic replacement
is preferred. This review considers the characteristics of stable and unstable
fractures of the radial head, as well as discussing the debatable
aspects of management, in light of the current best evidence. Cite this article:
Controversy surrounds the management of displaced
three- and four-part fractures of the proximal humerus. The percutaneous
Resch technique of stabilisation involves minimal soft-tissue dissection
and a reduced risk of stiffness and avascular necrosis. However,
it requires a second operation to remove Kirschner wires and the
humeral block. We describe a modification of this technique that
dispenses with the need for this second operation and relies on
a sequential pattern of screw placement. We report the outcome of
32 three- or four-part fractures of the proximal humerus treated
in this way at a mean follow-up of 3.8 years (2 to 8)). There were
14 men and 18 women with a mean age of 56 years (28 to 83). At final
follow-up the mean Oxford shoulder scores were 38 (31 to 44) and
39 (31 to 42), and the mean Constant scores were 79 (65 to 92) and
72 (70 to 80) for three- and four-part fractures, respectively. We
further analysed the results in patients aged <
60 years with
high-energy fractures and those aged ≥ 60 years with osteoporotic
fractures. There were no cases of nonunion or avascular necrosis. The results were good and comparable to those previously reported
for the Resch technique and other means of fixation for proximal
humeral fractures. We would recommend this modification of the technique
for the treatment of displaced three-part and four-part fractures
in patients both younger and older than 60 years of age.
Our aim in this pilot study was to evaluate the fixation of, the bone remodelling around, and the clinical outcome after surgery of a new, uncemented, fully hydroxyapatite-coated, collared and tapered femoral component, designed specifically for elderly patients with a fracture of the femoral neck. We enrolled 50 patients, of at least 70 years of age, with an acute displaced fracture of the femoral neck in this prospective single-series study. They received a total hip replacement using the new component and were followed up regularly for two years. Fixation was evaluated by radiostereometric analysis and bone remodelling by dual-energy x-ray absorptiometry. Hip function and the health-related quality of life were assessed using the Harris hip score and the EuroQol-5D. Up to six weeks post-operatively there was a mean subsidence of 0.2 mm (−2.1 to +0.5) and a retroversion of a mean of 1.2° (−8.2° to +1.5°). No component migrated after three months. The patients had a continuous loss of peri-prosthetic bone which amounted to a mean of 16% (−49% to +10%) at two years. The mean Harris hip score was 82 (51 to 100) after two years. The two-year results from this pilot study indicate that this new, uncemented femoral component can be used for elderly patients with osteoporotic fractures of the femoral neck.
