Ten patients who suffered iatrogenic injury to a vertebral artery during anterior cervical decompression were reviewed to assess the mechanisms of injury, their operative management, and the subsequent outcome. All had been undergoing a partial vertebral body resection for spondylitic radiculopathy or myelopathy (4), tumour (2), ossification of the posterior longitudinal ligament (1),
The primary aim of this study was to establish the cost-effectiveness of the early fixation of displaced midshaft clavicle fractures. A cost analysis was conducted within a randomized controlled trial comparing conservative management (n = 92) Aims
Patients and Methods
Cephalomedullary nails (CMNs) are commonly used for the treatment of intertrochanteric hip fractures. Total hip arthroplasty (THA) may be used as a salvage procedure when fixation fails in these patients. The aim of this study was to analyze the complications of THA following failed intertrochanteric hip fracture fixation using a CMN. Patients who underwent THA were identified from the 5% subset of Medicare Parts A/B between 2002 and 2015. A subgroup involving those with an intertrochanteric fracture that was treated using a CMN during the previous five years was identified and compared with the remaining patients who underwent THA. The length of stay (LOS) was compared using both univariate and multivariate analysis. The incidence of infection, dislocation, revision, and re-admission was compared between the two groups, using multivariate analysis adjusted for demographic, hospital, and clinical factors.Aims
Patients and Methods
There is little information about how to manage patients with a recurvatum deformity of the distal tibia and osteoarthritis (OA) of the ankle. The aim of this study was to evaluate the functional and radiological outcome of addressing this deformity using a flexion osteotomy and to assess the progression of OA after this procedure. A total of 39 patients (12 women, 27 men; mean age 47 years (28 to 72)) with a distal tibial recurvatum deformity were treated with a flexion osteotomy, between 2010 and 2015. Nine patients (23%) subsequently required conversion to either a total ankle arthroplasty (seven) or an arthrodesis (two) after a mean of 21 months (9 to 36). A total of 30 patients (77%), with a mean follow-up of 30 months (24 to 76), remained for further evaluation. Functional outcome, sagittal ankle joint OA using a modified Kellgren and Lawrence Score, tibial lateral surface (TLS) angle, and talar offset ratio (TOR) were evaluated on pre- and postoperative weight-bearing radiographs.Aims
Patients and Methods
We have reviewed retrospectively 80 patients who were treated for traumatic fractures of the femur with a Grosse-Kempf nail to assess the incidence and causes of persisting pain in the proximal thigh. At a mean of 21 months after operation 33 patients had residual pain severe enough to interfere with their lifestyle or mobility. This was in the region of the scar on the greater trochanter in three-quarters of the patients. Only four showed no radiological abnormality. There was
Aims. After intercalary resection of a bone tumour from the femur,
reconstruction with a vascularized fibular graft (VFG) and massive
allograft is considered a reliable method of treatment. However,
little is known about the long-term outcome of this procedure. The
aims of this study were to determine whether the morbidity of this
procedure was comparable to that of other reconstructive techniques,
if it was possible to achieve a satisfactory functional result, and
whether biological reconstruction with a VFG and massive allograft
could achieve a durable, long-lasting reconstruction. Patients and Methods. A total of 23 patients with a mean age of 16 years (five to 40)
who had undergone resection of an intercalary bone tumour of the
femur and reconstruction with a VFG and allograft were reviewed
clinically and radiologically. The mean follow-up was 141 months
(24 to 313). The mean length of the fibular graft was 18 cm (12 to
29). Full weight-bearing without a brace was allowed after a mean
of 13 months (seven to 26). Results. At final follow-up, the mean Musculoskeletal Tumor Society Score
of 22 evaluable patients was 94% (73 to 100). Eight major complications,
five fractures (21.7%), and three nonunions (13%) were seen in seven
patients (30.4%). Revision-free survival was 72.3% at five, ten,
and 15 years, with
The aims of this study were to analyse the long-term outcome
of vascularised fibular graft (VFG) reconstruction after tumour
resection and to evaluate the usefulness of the method. We retrospectively reviewed 49 patients who had undergone resection
of a sarcoma and reconstruction using a VFG between 1988 and 2015.
Their mean follow-up was 98 months (5 to 317). Reconstruction was
with an osteochondral graft (n = 13), intercalary graft (n = 12),
inlay graft (n = 4), or resection arthrodesis (n = 20). We analysed
the oncological and functional outcome, and the rate of bony union
and complications.Aims
Patients and Methods
This study reviews the use of a titanium mesh cage (TMC) as an
adjunct to intramedullary nail or plate reconstruction of an extra-articular
segmental long bone defect. A total of 17 patients (aged 17 to 61 years) treated for a segmental
long bone defect by nail or plate fixation and an adjunctive TMC
were included. The bone defects treated were in the tibia (nine),
femur (six), radius (one), and humerus (one). The mean length of
the segmental bone defect was 8.4 cm (2.2 to 13); the mean length
of the titanium mesh cage was 8.3 cm (2.6 to 13). The clinical and
radiological records of the patients were analyzed retrospectively.Aims

This study aimed to evaluate implant survival of reverse hybrid
total hip arthroplasty (THA) at medium-term follow-up. A consecutive series of 1082 THAs in 982 patients with mean follow-up
of 7.9 years (5 to 11.3) is presented. Mean age was 69.2 years (21
to 94). Of these, 194 (17.9%) were in patients under 60 years, 663
(61.3%) in female patients and 348 (32.2%) performed by a trainee.
Head size was 28 mm in 953 hips (88.1%) or 32 mm in 129 hips (11.9%).
Survival analysis was performed and subgroups compared using log
rank tests.Aims

We conducted a study to identify factors that are prognostic
of the outcome of extracorporeal shockwave therapy (ESWT) for calcific
tendinitis of the shoulder. Since 1998, patients with symptomatic calcific tendinitis of
the rotator cuff have been treated with ESWT using an electrohydraulic
mode shockwave device. One year after ESWT, patients were grouped
according to the level of resorption of calcification.Aims
Patients and Methods
Displaced fractures of the lateral condyle of the humerus are
frequently managed surgically with the aim of avoiding nonunion,
malunion, disturbances of growth and later arthritis. The ideal
method of fixation is however not known, and treatment varies between
surgeons and hospitals. The aim of this study was to compare the
outcome of two well-established forms of surgical treatment, Kirschner
wire (K-wire) and screw fixation. A retrospective cohort study of children who underwent surgical
treatment for a fracture of the lateral condyle of the humerus between
January 2005 and December 2014 at two centres was undertaken. Pre,
intraoperative and postoperative characteristics were evaluated. A total of 336 children were included in the study. Their mean
age at the time of injury was 5.8 years (0 to 15) with a male:female
patient ratio of 3:2. A total of 243 (72%) had a Milch II fracture
and the fracture was displaced by > 2 mm in 228 (68%). In all, 235
patients underwent K-wire fixation and 101 had screw fixation. Aims

This study identifies early risk factors for symptomatic nonunion
of displaced midshaft fractures of the clavicle that aid identification
of an at risk group who may benefit from surgery. We performed a retrospective study of 88 patients aged between
16 and 60 years that were managed non-operatively. Aims
Methods
Between 2005 and 2012, 50 patients (23 female, 27 male) with
nonunion of the humeral shaft were included in this retrospective
study. The mean age was 51.3 years (14 to 88). The patients had
a mean of 1.5 prior operations ( All patients were assessed according to a specific risk score
in order to devise an optimal and individual therapy plan consistent
with the Diamond Concept. In 32 cases (64%), a change in the osteosynthesis
to an angular stable locking compression plate was performed. According
to the individual risk an additional bone graft and/or bone morphogenetic
protein-7 (BMP-7) were applied. A successful consolidation of the nonunion was observed in 37
cases (80.4%) with a median healing time of six months (IQR 6).
Younger patients showed significantly better consolidation. Four
patients were lost to follow-up. Revision was necessary in a total
of eight (16%) cases. In the initial treatment, intramedullary nailing
was most common. Methods
Results
To evaluate the hypothesis that failed osteosynthesis of periprosthetic
Vancouver type B1 fractures can be treated successfully with stem
revision using a transfemoral approach and a cementless, modular,
tapered revision stem with reproducible rates of fracture healing,
stability of the revision stem, and clinically good results. A total of 14 patients (11 women, three men) with a mean age
of 72.4 years (65 to 90) undergoing revision hip arthroplasty after
failed osteosynthesis of periprosthetic fractures of Vancouver type
B1 were treated using a transfemoral approach to remove the well-fixed
stem before insertion of a modular, fluted titanium stem which obtained
distal fixation. These patients were clinically and radiologically
followed up for a mean 52.2 months (24 to 144).Aims

Objectives. A successful outcome following treatment of nonunion requires the correct identification of all of the underlying cause(s) and addressing them appropriately. The aim of this study was to assess the distribution and frequency of causative factors in a consecutive cohort of nonunion patients in order to optimise the management strategy for individual patients presenting with nonunion. Methods. Causes of the nonunion were divided into four categories: mechanical; infection; dead bone with a gap; and host. Prospective and retrospective data of 100 consecutive patients who had undergone surgery for long bone fracture nonunion were analysed. Results. A total of 31% of patients had a single attributable cause, 55% had two causes, 14% had three causes and 1% had all four. Of those (31%) with only a single attributable cause, half were due to a mechanical factor and a quarter had dead bone with a gap. Mechanical causation was found in 59% of all patients, dead bone and a gap was present in 47%, host factors in 43% and infection was a causative factor in 38% of patients. In all, three of 58 patients (5%) thought to be aseptic and two of nine (22%) suspected of possible infection were found to be infected. A total of 100% of previously treated patients no longer considered to have ongoing infection, had multiple positive microbiology results. Conclusion. Two thirds of patients had multiple contributing factors for their nonunion and 5% had entirely unexpected infection. This study highlights the importance of identifying all of the aetiological factors and routinely testing tissue for infection in treating nonunion. It raises key points regarding the inadequacy of a purely radiographic nonunion classification system and the variety of different definitions for atrophic nonunion in the current mainstream classifications used for nonunion.

The aims of this retrospective study were to report the feasibility
of using 3D-printing technology for patients with a pelvic tumour
who underwent reconstruction. A total of 35 patients underwent resection of a pelvic tumour
and reconstruction using 3D-printed endoprostheses between September
2013 and December 2015. According to Enneking’s classification of
bone defects, there were three Type I lesions, 12 Type II+III lesions,
five Type I+II lesions, two Type I+II+III lesions, ten type I+II+IV
lesions and three type I+II+III+IV lesions. A total of three patients
underwent reconstruction using an iliac prosthesis, 12 using a standard
hemipelvic prosthesis and 20 using a screw-rod connected hemipelvic
prosthesis.Aims
