Donald E Fry
BACKGROUND: Pressure irrigation of surgical incisions and traumatic wounds is commonly used to prevent infections. Commercial pressure irrigation devices have proliferated rapidly, but scientific validation of clinical benefit or appropriate use remains uncertain. METHODS: The published experimental and clinical investigations of pressure irrigation have been reviewed since the introduction of the Waterpik device in 1967 to identify the evidence for use to prevent soft tissue infections associated with injury wounds or surgical incisions...

Halah Kutaish, R Stern, L Drittenbass, M Assal
Chopart complex injuries (CCIs) are thought to be uncommon; however, recent literature states the rate of misdiagnosis to be between 20 and 41%. Chopart complex injuries are not ankle injuries, with which they are initially confused due to a similar mechanism of trauma in many cases. Injury to the Chopart complex commonly affects multiple structures. The key to optimal treatment is a high index of clinical suspicion combined with timely accurate imaging studies. Careful diagnostic workup with high-quality radiographs of the foot in neutral position should be obtained...

Osteomyelitis of the digit is a challenging problem that can result in amputation. We describe 13 cases of osteomyelitis involving bones of the hand managed with a novel technique. We reviewed records of 12 patients (13 digits) who had joint-spanning, antibiotic-eluting (tobramycin or vancomycin), methylmethacrylate spacers placed as definitive, single-stage treatment for digital osteomyelitis. The primary outcome was digit salvage. Secondary outcomes were infection eradication (no recurrence at 3 months) and spacer removal...

BACKGROUND We explored the application of 3-dimensional (3D) printing technology in treating giant cell tumors (GCT) of the proximal tibia. A tibia block was designed and produced through 3D printing technology. We expected that this 3D-printed block would fill the bone defect after en-bloc resection. Importantly, the block, combined with a standard knee joint prosthesis, provided attachments for collateral ligaments of the knee, which can maintain knee stability. MATERIAL AND METHODS A computed tomography (CT) scan was taken of both knee joints in 4 patients with GCT of the proximal tibia...

Mycobacterium marinum is a well-known pathogenic mycobacterium for skin and soft tissue infections and is associated with fishes and water. Among nontuberculous mycobacteria (NTM), it is the leading cause of extrarespiratory human infections worldwide. In addition, there is a specific scientific interest in M. marinum because of its genetic relatedness to Mycobacterium tuberculosis and because experimental infection of M. marinum in fishes mimics tuberculosis pathogenesis. Microbiological characteristics include the fact that it grows in 7 to 14 days with photochromogenic colonies and is difficult to differentiate from Mycobacterium ulcerans and other mycolactone-producing NTM on a molecular basis...

AIMS: Instability of the hip is the most common mode of failure after reconstruction with a proximal femoral arthroplasty (PFA) using an endoprosthesis after excision of a tumour. Small studies report improved stability with capsular repair of the hip and other techniques, but these have not been investigated in a large series of patients. The aim of this study was to evaluate variables associated with the patient and the operation that affect post-operative stability. We hypothesised an association between capsular repair and stability...

Scapholunate ligament (SLL) injury is the most frequent injury of the intrinsic carpal ligaments. The dorsal part of the SLL is the most important part for the stability of the scapholunate joint, and tears of this part and at least one of its secondary capsular attachments cause scapholunate dissociation. The arthroscopic technique most frequently used for acute injuries is reduction and fixation with Kirschner wires, and techniques that involve a primary repair of the injured ligament are performed by open surgery with efficient results...

Acromioclavicular joint injuries are one of the most common shoulder injuries, and there are a variety of treatment options. Recently, there have been newer arthroscopic techniques that have addressed coracoid and clavicle fracture risk by using a knotted suture-button fixation through a single, small bone tunnel with additional looped soft-tissue graft stabilization. Although clinical outcomes have been good to excellent, there have still been instances of knot and hardware irritation. The described technique builds on the latest advances and achieves an anatomic coracoclavicular (CC) reconstruction through a single knotless CC fixation device with additional soft-tissue allograft reconstruction of the CC ligaments...

Treatment of a nonunion of the proximal humerus remains a challenge because of the small proximal fragment and poor central cancellous bone stock of the humeral head. In this report, we describe our experience using a "half-folded" pedicled scapular bone flap with an anatomical locking plate to treat an atrophic nonunion of the proximal humerus in a 64-year-old right-handed woman. The patient had fallen and experienced a common humeral neck fracture 2.5 years previously. During the operation, we elevated the pedicled scapular bone flap, which measured 8...

Giant cell tumour of bone (GCTB) is an intermediate locally aggressive primary bone tumour, occurring mostly at the meta-epiphysis of long bones. Overexpression of receptor activator of nuclear factor kappa-B ligand (RANKL) by mononuclear neoplastic stromal cells promotes recruitment of numerous reactive multinucleated osteoclast-like giant cells, causing lacunar bone resorption. Preferential treatment is curettage with local adjuvants such as phenol, alcohol or liquid nitrogen. The remaining cavity may be filled with bone graft or polymethylmethacrylate (PMMA) bone cement; benefits of the latter are a lower risk of recurrence, possibility of direct weight bearing and early radiographic detection of recurrences...

A 2-year-old, 3.8-kg male Rhode Island red rooster was examined for lameness and progressive swelling of the right foot of several month's duration. Radiographs of the right foot demonstrated soft tissue swelling and a smoothly marginated periosteal reaction evident of inflammation affecting the bones. Results of a complete blood count showed a moderate leukocytosis and an elevated total protein concentration. Systemic antibiotic and anti-inflammatory therapy was started, but the bird had not improved at recheck examination...

The knee joint is involved in a wide variety of arthritides, and imaging has always played a major role in both aiding diagnosis and assessing the severity of such diseases. Plain film radiography has traditionally been used as the primary imaging modality for radiographic diagnosis of arthritis. However, magnetic resonance imaging (MRI) shows a greater sensitivity to both the bone and soft tissue features of this group of conditions. This article reviews the imaging features of osteoarthritis (OA) of the knee shown on MRI and the criteria used to diagnose this condition...

The use of deformable image registration methods in the context of adaptive radiotherapy leads to uncertainties in the simulation of the administered dose distributions during the treatment course. Evaluation of these methods is a prerequisite to decide if a plan adaptation will improve the individual treatment. Current approaches using manual references limit the validity of evaluation, especially for low contrast regions. In particular for the head and neck region, the highly flexible anatomy and the low soft tissue contrast in control images pose a challenge to image registration and its evaluation...

Large animal models of osteoarthritis are a necessary testing ground for FDA approval of human medicine applications. Sheep models have advantages over other available large animals, but development and progression of osteoarthritis in sheep is exceedingly slow, which handicaps progress in development of potential treatments. We combined oblique angle forced exercise to increase stress on the stifle, with surgical destabilization to hasten the development of osteoarthritis in ewes. Methods for early detection of clinical signs included radiography, urine, and serum biomarker assays and gait analysis and ex vivo we used microcomputed tomography and macroscopic joint analysis...

We describe a unique, utilitarian reconstructive treatment option known as tibial "spackling" for chronic, localized medial joint line pain corresponding with progressive radiographic peripheral medial tibial bone loss beneath a well-fixed revision total knee arthroplasty tibial baseplate. It is believed that this localized pain is due to chronic irritation of the medial capsule and collateral ligament from the prominent medial edge of the tibial component. In the setting of failed nonoperative treatment, our experience with utilizing bone cement to reconstruct the medial tibial bone defect and create a smooth medial tibial surface has been successful in eliminating chronic medial soft tissue irritation...

BACKGROUND: Tenosynovial giant cell tumor (TSGCT), also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis, is the most common benign tumor of the tendon and synovium. The intra-articular diffuse type can present as a large infiltrative mass involving adjacent soft tissue and sometimes causes secondary destruction of bone, which leads to radiographic and clinical concern for malignancy. The tumor may also be purely extra-articular. CASE: Here, we report the fine needle aspiration cytology findings of 2 cases of diffuse-type TSGCT with large mononuclear cells with eccentric nuclei, finely granular cytoplasm, and a peripheral well-defined cytoplasmic rim of hemosiderin ("ladybird cells")...

Impingement syndrome of the ankle is a clinical diagnosis caused posttraumatically by overuse due to repetitive mechanical loading or the presence of predisposing anatomical variants. Ankle impingement syndrome is characterized by chronic pain and limited range of movement caused by mechanical compression of bony or soft tissues within the joint compartments. Ankle impingement syndrome is classified according to the various anatomical locations around the tibiotalar joint as anterior, anterolateral, anteromedial, posterior or posteromedial...

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare condition in the elderly and can appear as a first presentation of various types of rheumatic and malignant diseases. We presented a 62-year-old man with the diagnosis of RS3PE based on the clinical sign and laboratory data. Because of the possibility of associated malignancies in RS3PE, FDG PET/CT was performed to exclude occult tumors. The images showed multiple, symmetrically, diffusely increased F-FDG uptake in the soft tissue around joints and bones in the shoulders, hips, knees, and ankles...
