Postoperative rehabilitation regimens following ankle arthrodesis vary considerably. A systematic review was conducted to determine the evidence for weightbearing recommendations following ankle arthrodesis, and to compare outcomes between different regimens. MEDLINE, Web of Science, Embase, and Scopus databases were searched for studies reporting outcomes following ankle arthrodesis, in which standardized postoperative rehabilitation regimens were employed. Eligible studies were grouped according to duration of postoperative nonweightbearing: zero to one weeks (group A), two to three weeks (group B), four to five weeks (group C), or six weeks or more (group D). Outcome data were pooled and compared between groups. Outcomes analyzed included union rates, time to union, clinical scores, and complication rates.Aims

The introduction of a trabecular tantalum rod
has been proposed for the management of early-stage osteonecrosis of
the femoral head but serves as a single-point of support of the
necrotic lesion. We describe a technique using two or three 4.2
mm (or later 4.7 mm) tantalum pegs for the prevention of collapse
of the necrotic lesion. We prospectively studied 21 patients (26
hips) with non-traumatic osteonecrosis of the femoral head treated
in this manner. Of these, 21 patients (24 hips) were available for
radiological and clinical evaluation at a mean follow-up of 46 months
(18 to 67). Radiological assessment showed that only eight hips
deteriorated according to the Association Research Circulation Osseous
classification, and four hips according to the Classification of
the Japanese Investigation Committee of Health and Welfare. Functional
improvement was obtained with an improvement in the mean Harris
hip score from 65.2 (33.67 to 95) to 88.1 (51.72 to 100), the mean
Merle D’Aubigné-Postel score from 13 (6 to 18) to 16 (11 to 18),
a mean visual analogue score for pain from 5.2 (0 to 9.5) to 2.6
(0 to 7), and the mean Short-Form 36 score from 80.4 (56.8 to 107.1)
to 92.4 (67.5 to 115.7). Of these 24 hips followed for a minimum
of 18 months, three were considered as failures at the final follow-up,
having required total hip replacement. One of the hips without full
follow-up was also considered to be a failure. In more than two-thirds

Reverse shoulder arthroplasty (RSA) reliably improves shoulder pain and function for a variety of indications. However, the safety and efficacy of RSA in elderly patients is largely unknown. The purpose of this study was to report the mortality, morbidity, complications, reoperations, and outcomes of primary RSA in patients aged > 80 years. Between 2004 and 2013, 242 consecutive primary RSAs were performed in patients aged > 80 years (mean 83.3 years (Aims

We report a prospective case-controlled study which compared the outcome of knee replacement in seriously deformed and slightly deformed knees. There were 51 knees with varus or valgus deformity greater than 20 degrees matched for age, gender, disease, type of prosthesis and time of operation with a control group in which the alignment of the leg was within 5 degrees of normal. The
We evaluated the efficacy of anterior fusion alone compared with combined anterior and posterior fusion for the treatment of degenerative cervical kyphosis. Anterior fusion alone was undertaken in 15 patients (group A) and combined anterior and posterior fusion was carried out in a further 15 (group B). The degree and maintenance of the angle of correction, the incidence of graft subsidence, degeneration at adjacent levels and the rate of fusion were assessed radiologically and clinically and the rate of complications recorded. The mean angle of correction in group B was significantly higher than in group A (p = 0.0009). The mean visual analogue scale and the neck disability index in group B was better than in group A (p = 0.043, 0.0006). The mean operation time and the blood loss in B were greater than in group A (p <
0.0001, 0.037). Pseudarthrosis, subsidence of the cage, and problems related to the hardware were more prevalent in group A than in group B (p = 0.034, 0.025, 0.013). Although the combined procedure resulted in a longer operating time and greater blood loss than with anterior fusion alone, our results suggest that for the treatment of degenerative cervical kyphosis the combined approach leads to better maintenance of sagittal alignment, a higher rate of fusion, a lower incidence of complications and a better
Cemented femoral stems with force closed fixation
designs have shown good clinical results despite high early subsidence.
A new triple-tapered stem in this category (C-stem AMT) was introduced
in 2005. This study compares this new stem with an established stem
of similar design (Exeter) in terms of migration (as measured using radiostereometric
analysis), peri-prosthetic bone remodelling (measured using dual
energy x-ray densitometry, DXA), Oxford Hip Score, and plain radiographs. . A total of 70 patients (70 hips) with a mean age of 66 years
(53 to 78) were followed for two years. Owing to missing data of
miscellaneous reasons, the final analysis represents data from 51
(RSA) and 65 (DXA) patients. Both stems showed a typical pattern
of migration: Subsidence and retroversion that primarily occurred
during the first three months. C-stem AMT subsided less during the
first three months (p = 0.01), before stabilising at a subsidence rate
similar to the Exeter stem from years one to two. The rate of migration
into retroversion was slightly higher for C-stem AMT during the
second year (p = 0.03). Whilst there were slight differences in
movement patterns between the stems, the C-stem AMT exhibits good

Studies have addressed the issue of increasing prevalence of work-related musculoskeletal (MSK) pain among different occupations. However, contributing factors to MSK pain have not been fully investigated among orthopaedic surgeons. Thus, this study aimed to approximate the prevalence and predictors of MSK pain among Saudi orthopaedic surgeons working in Riyadh, Saudi Arabia. A cross-sectional study using an electronic survey was conducted in Riyadh. The questionnaire was distributed through email among orthopaedic surgeons in Riyadh hospitals. Standardized Nordic questionnaires for the analysis of musculoskeletal symptoms were used. Descriptive measures for categorical and numerical variables were presented. Student’s t-test and Pearson’s χ2 test were used. The level of statistical significance was set at p ≤ 0.05.Introduction
Methods
The aim of this study was to estimate the cost-effectiveness of negative-pressure wound therapy (NPWT) in comparison with standard wound management after initial surgical wound debridement in adults with severe open fractures of the lower limb. An economic evaluation was conducted from the perspective of the United Kingdom NHS and Personal Social Services, based on evidence from the 460 participants in the Wound Management of Open Lower Limb Fractures (WOLLF) trial. Economic outcomes were collected prospectively over the 12-month follow-up period using trial case report forms and participant-completed questionnaires. Bivariate regression of costs (given in £, 2014 to 2015 prices) and quality-adjusted life-years (QALYs), with multiple imputation of missing data, was conducted to estimate the incremental cost per QALY gained associated with NPWT dressings. Sensitivity and subgroup analyses were undertaken to assess the impacts of uncertainty and heterogeneity, respectively, surrounding aspects of the economic evaluation.Aims

The aim is to assess the cost-effectiveness of patellofemoral arthroplasty (PFA) in comparison with total knee arthroplasty (TKA) for the treatment of isolated patellofemoral osteoarthritis (OA) based on prospectively collected data on health outcomes and resource use from a blinded, randomized, clinical trial. A total of 100 patients with isolated patellofemoral osteoarthritis were randomized to receive either PFA or TKA by experienced knee surgeons trained in using both implants. Patients completed patient-reported outcomes including EuroQol five-dimension questionnaire (EQ-5D) and 6-Item Short-Form Health Survey questionnaire (SF-6D) before the procedure. The scores were completed again after six weeks, three, six, and nine months, and again after one- and two-year post-surgery and yearly henceforth. Time-weighted outcome measures were constructed. Cost data were obtained from clinical registrations and patient-reported questionnaires. Incremental gain in health outcomes (quality-adjusted life-years (QALYs)) and incremental costs were compared for the two groups of patients. Net monetary benefit was calculated assuming a threshold value of €10,000, €35,000, and €50,000 per QALY and used to test the statistical uncertainty and central assumptions about outcomes and costs.Aims

The incidence of periprosthetic fractures of
the ankle is increasing. However, little is known about the outcome
of treatment and their management remains controversial. The aim
of this study was to assess the impact of periprosthetic fractures
on the functional and radiological outcome of patients with a total
ankle arthroplasty (TAA). A total of 505 TAAs (488 patients) who underwent TAA were retrospectively
evaluated for periprosthetic ankle fracture: these were then classified
according to a recent classification which is orientated towards
treatment. The outcome was evaluated clinically using the American
Orthopedic Foot and Ankle Society (AOFAS) score and a visual analogue
scale for pain, and radiologically. . A total of 21 patients with a periprosthetic fracture of the
ankle were identified. There were 13 women and eight men. The mean
age of the patients was 63 years (48 to 74). Thus, the incidence
of fracture was 4.17%. . There were 11 intra-operative and ten post-operative fractures,
of which eight were stress fractures and two were traumatic. The
prosthesis was stable in all patients. Five stress fractures were
treated conservatively and the remaining three were treated operatively. . A total of 17 patients (81%) were examined clinically and radiologically
at a mean follow-up of 53.5 months (12 to 112). The mean AOFAS score
at follow-up was 79.5 (21 to 100). The mean AOFAS score in those
with an intra-operative fracture was 87.6 (80 to 100) and for those
with a stress fracture, which were mainly because of varus malpositioning,
was 67.3 (21 to 93). Periprosthetic fractures of the ankle do not
