Soft Tissue Management of War Wounds to the Foot and Ankle
This article details the experiences of United States military reconstructive surgeons in the soft tissue management of war wounds of the foot and ankle resulting from the conflicts in Iraq and Afghanistan. War wounds from this conflict are commonly caused by blast and fragmentation, and are characteristically extensive, heterogeneous, and severe. Multiple serial débridement episodes are routinely necessary because of deterioration of the wounds over time, which is in contrast to civilian trauma wherein fewer débridement episodes are generally required. Wound therapy adjuncts, such as subatmospheric wound dressing and synthetic dermal replacement, have been used extensively with favorable results. Pedicled flaps, such as the distally based sural neurofasciocutaneous flap, are reliable, a......

Analysis of Ankle Range of Motion and Functional Outcome Following Total Ankle Arthoplasty
Abstract: The success of ankle joint replacement has primarily been reviewed with respect to patient morbidity and survivorship rather than patient satisfaction. A retrospective review was performed of 95 patients who had undergone a total ankle replacement and who had completed both postoperative range of motion fluoroscopy and a subjective patient score sheet. Collected data included age, body mass index, length of follow-up, presence of complications, performance of adjunctive procedures, range of motion, and the etiology of the end-stage arthritis. These variables were then compared with patient satisfaction to see if there were any predictive conditions of successful outcomes. Patients older than 60 years and those with a body mass index (BMI) less than 30 demonstrated a significant p......

Salvage arthrodesis for failed total ankle arthroplasty.
Authors: Doets HC, Zürcher AW
Background and purpose Total ankle arthroplasty (TAA) has gained popularity in recent years. If it fails, however, salvage arthrodesis must be reliable as a rescue procedure. We therefore investigated the clinical, radiographic, and subjective outcome after salvage arthrodesis in a consecutive group of patients, and concentrated on the influence of the method of fixation on union rate and on salvage in inflammatory joint disease. Patients and methods Between 1994 and 2005, salvage arthrodesis was performed on 18 ankles (18 patients). Diagnosis was inflammatory joint disease (IJD) in 15 cases and osteoarthritis (OA) in 3. Tibio-talar fusion was performed in 7 ankles, and tibio-talocalcaneal fusion in 11. Serial radiographs were studied for time to unio......

Microfracture for chondral defects of the talus: maintenance of early results at midterm follow-up
Abstract We determined whether the early improvement in symptoms and function after microfracture in the management of articular cartilage
defects of the talus is maintained at mid term follow-up. Factors influencing outcome and postoperative magnetic resonance
imaging were also evaluated. We performed data collection prospectively using the Hannover Scoring System for the ankle (HSS)
and a Visual Analog Scale (VAS) for pain and function preoperatively, at 1 ± 0.1 year (45 ankles), 2 ± 0.4 years (45 ankles),
and at an average of 5.8 ± 2.0 years (39 ankles) postoperatively. MRI was used to assess cartilage repair tissue based on
the following variables: degree of defect repair and filling of the defect, integration to border zo......

Pigmented villonodular synovitis of the elbow treated with the tsuge wide joint exposure technique.
This article describes a case of a 29-year-old woman with PVNS of the right elbow who was treated by total synovectomy using the Tsuge technique. Tsuge reported a new surgical technique for debridement arthroplasty using a posterolateral approach to the elbow in 1987. He has also reported using this procedure during arthroplasty for posttraumatic stiff elbow and for synovectomy in rheumatoid arthritis. This approach permits easy dislocation of the elbow and provides a good view of the whole joint. Although the recurrence rate of PVNS of the elbow is high, our patient has retained good elbow function with no evidence of local recurrence at 30 months postoperatively.

Influences of anti-tumour necrosis factor agents on postoperative recovery in patients with rheumatoid arthritis
Abstract The aim of this study is to investigate the influences of the anti-tumour necrosis factor (TNF) agents infliximab and etanercept
on the postoperative recovery of patients with rheumatoid arthritis (RA). We also investigated the effects of biologics on
wound healing. Patients with RA were split into a TNF group (n = 39) that underwent 39 operations and were treated with anti-TNF agents, and a non-TNF group (n = 74) that underwent 74 operations and were treated only with conventional disease-modifying antirheumatic drugs. Operations
included ankle arthrodesis and total arthroplasty of the hip, knee, elbow, shoulder and ankle. Adverse events (AEs) of surgical
wounds, time for complete wound healing, febrile period after operation and recovery parameters after o......

Moje First Metatarsophalangeal Replacement—A Case Series with Functional Outcomes Using the AOFAS-HMI Score
We report the functional results of a case series of Moje first metatarsophalangeal total joint replacements carried out between February 2001 and November 2006. All patients who underwent Moje arthroplasty under the care of a single surgeon were included; outcome scores and complications were recorded annually. A total of 32 joints in 29 consecutive patients were followed for a mean duration of 34 (range 6 to 74) months, and the mean patient age at the time of operation was 56 (range 38 to 79) years. Hallux rigidus was the primary diagnosis in 28 (87.5%) of the cases. The mean American Orthopaedic Foot & Ankle Society Hallux-Metatarsophalangeal-Interphalangeal score at final follow-up was 74/100 (range 9 to 100), with 13 (40.63%) joints rated good to excellent. Two (6.25%) joints were rev......

[Peripheral arterial disease in women.]
Authors: Aboyans V, Salazar J, Lacroix P
The widespread use of the ankle-brachial index (ABI) enabled to reveal the high prevalence of lower extremities peripheral arterial disease (PAD) in women, even higher than in men in several series. Nonetheless, the use of a same ABI threshold for men and women may overestimate the prevalence of subclinical PAD in women. Conversely, the clinical manifestations of PAD are more often atypical in women, with as a result, a delayed diagnosis and management. The level of association between cardiovascular disease risk factors and PAD is similar in both genders. To date, there is no evidence for any association between PAD and different hormonal events in women. Despite an inverse association between hormonal replacement therapy (HRT) after menopause ......

Mid-term results of joint-preserving procedures by a modified Mann method for big toe deformities in rheumatoid patients undergoing forefoot surgeries
This study aimed to evaluate joint-preserving procedures by a modified Mann method for rheumatoid forefoot deformities and
their functional outcomes in the mid-term. Eleven feet in seven patients underwent forefoot surgery using a modified Mann
method for the big toe, combined with offset osteotomy or resection arthroplasty of the lesser toes. The mean follow-up period
was 3.6 years. The mean score on the Japanese Society for Surgery of the Foot scale for rheumatoid arthritis foot and ankle
joints improved from 44.0 to 72.0. The mean hallux valgus angle improved from 39.4° to 20.5° and the mean M1M5 angle improved
from 31.1° to 25.8°. However, deformities involving a hallux valgus angle of more than 25.0° recurred in three feet at the
latest follow-up, although the patients......

Human Immunodeficiency Virus Disclosure and Patient Confidentiality in Orthopaedic Procedures
A thirty-two-year-old man with hemophilia whose chief complaint was knee pain was referred by his hematologist for consideration of a total knee arthroplasty. On his initial visit, the patient was seen and evaluated with his pregnant wife and their infant child present in the examination room at his request. During the review of systems and past medical history, the treating surgeon inquired into the status of his human immunodeficiency virus (HIV) viral load and CD4 count. At that point, the patient denied ever testing positive for HIV. Later, in a private discussion, the patient confirmed his HIV-positive status. He admitted that his wife was unaware of his history, and he stated that he did not wish her to know. The surgeon explained to the patient that his HIV history posed a major hea......

Oxygen tensiometry as a predictor of wound healing in total ankle arthroplasty.
CONCLUSION: Oxygen tensiometry is not thought to be useful for predicting patients at risk for postoperative wound healing complications after TAA, suggesting that, if adequate pulses are present before surgery, the trauma of using excessive superficial traction on the skin during surgery is more responsible for wound healing problems than the underlying blood supply.

Gallery of uncommon orthopedic implants: a guide for emergency radiologist
Abstract The purpose of this gallery of orthopedic implants was to provide a reference for emergency radiologists to quickly identify
uncommon devices in the shoulders, hips, and extremities. The cases presented in this exhibit will include unusual arthroplasties
and prostheses as well as bone graft implants (including allograft and autograft). Bone grafts are frequently used for the
treatment of bone defects, which may be caused by trauma, infection, or avascularity. Autogenous cancellous, corticocancellous,
or cortical bone grafts are often used, either free or vascularized [1]. Alternative bone graft substitutes are also used. An obvious complication of bone grafts is the failure of incorporation.
Joint arthroplasty is the most frequently performed orthopedic procedure a......

Long-term clinical results of the Oxford medial unicompartmental knee arthroplasty
Abstract The purposes of this study were to investigate the mode of failure and survivorship of an independently performed series of
medial Oxford unicompartmental knee arthroplasties. The study included 43 knees in 40 patients with a mean follow-up of 14.88 years:
13 knees (11 patients) had revision surgery (30%), and ten patients required conversion to total knee prosthesis. The mean
International Knee Society (IKS) scores at the time of the revision were 145.52 [standard deviation (SD): 39.90, range: 167–200].
The overall alignment of the knee was restored to neutral, with a hip-knee-ankle (HKA) angle average of 178° (SD: 3.21°, range:
170–186°). Survivorship, as defined by an endpoint of failure for any reason, showed that the survival rate at five year......

Endoprosthetic reconstruction of the distal tibia and ankle joint after resection of primary bone tumours.
We report the outcome of six patients treated between 1981 and 2007. There were four males and two females, with a mean age of 43.5 years (15 to 75), and a mean follow-up of 9.6 years (1 to 27). No patient developed a local recurrence or metastasis. Two of the six went on to have a below-knee amputation for persistent infection after a mean 16 months (1 to 31). The four patients who retained their endoprosthesis had a mean musculoskeletal tumour society score of 70% and a mean Toronto extremity salvage score of 71%. All were pain free and able to perform most activities of daily living in comfort. A custom-made endoprosthetic replacement of the distal tibia and ankle joint is a viable treatment option for carefully selected patients with a primary bone tumour. Patients should, however, be ......

Opening wedge tibial osteotomy for large varus deformity with CeraverTM resorbable beta tricalcium phosphate wedges
Abstract The results in 53 knees that had been treated by proximal tibial opening-wedge osteotomy for large varus deformity and osteoarthritis
of the medial compartment were evaluated after a mean length of follow-up of ten years (range, 8–12 years). We used a porous
beta-tricalcium phosphate (β-TCP) wedge because it is resorbable and osteoinductive. All osteotomies were completely consolidated
and complete osseointegration of the remnant of the β-TCP wedge took place. However, after a mean maximum follow-up of ten years
none of the cases showed complete resorption. After ten years, 40 (81%) of the 53 knees had an excellent or good result, and
in 13 knees there was recurrent pain for which six had an arthroplasty. Although the results deteriorated with time, t......

Bone Graft Substitutes and Allografts for Reconstruction of the Foot and Ankle
In reconstructive foot and ankle surgery, the use of bone graft is common. Whether for trauma, acquired or congenital deformities, arthrodeses, joint replacement, bone loss from infection, or bone tumor resection, the foot and ankle surgeon must be knowledgeable about current bone grafting options to make informed decisions. Innovation and technologic advances have produced an impressive and exciting array of options, advancing us closer to mimicking the gold standard: autograft. However, the sheer volume of available products makes it challenging for the foot and ankle surgeon to stay abreast of current bone graft technology. The purpose of this article is to simplify and classify current bone grafting options, discuss advantages and disadvantages, and provide relevant clinical examples. ......
