Nontuberculous mycobacteria (NTM) infections involving anti-interferon-gamma (IFN-γ)-neutralizing autoantibodies have been described in previously immunocompetent adults. To investigate the factors underlying various disease manifestations, we reviewed 35 articles published between January 2004 and November 2016 and identified 111 NTM patients with anti-IFN-γ autoantibodies. Rapidly growing mycobacteria (RGM) accounted for 53% of the isolated species. RGM were predominant among the NTM species isolated from Thai (73%), Chinese (58%) and Filipino (56%) patients, whereas M...

INTRODUCTION: Heterotopic ossification (HO) is defined as ectopic bone formation around peripheral joints and in soft tissues. HO is a common complication of diseases of the central nervous system, such as spinal cord injury (SCI) and traumatic brain injury. HO is seen in up to 50% of patients with SCI and typically occurs in the first 12 weeks after onset of injury. Although no treatment method is proven to be curative, nonsteroidal anti-inflammatory drugs, irradiation of the involved body part and bisphosphonates are commonly used in the management of HO...

Radial club hand is a complex congenital abnormality of the radial or pre-axial border of the upper extremity. It has a wide range of phenotypes from hypoplasia of the thumb to complete absence of the radius and the first ray. Centralization with tendon transfer is a popular method for maintaining the correct position of radial club hand. On the other hand, various corrections were devised, e.g. radialization after distraction to emphasize the fact that the head of the ulna is positioned under the radial carpal bones and is no longer placed in a slot in the center of the carpus, microvascular epiphysis transfer, gradual correction using Ilizarov method, for Bayne Type III or Type IV...

Kinematic models of lower limb joints have several potential applications in musculoskeletal modelling of the locomotion apparatus, including the reproduction of the natural joint motion. These models have recently revealed their value also for in vivo motion analysis experiments, where the soft-tissue artefact is a critical known problem. This arises at the interface between the skin markers and the underlying bone, and can be reduced by defining multibody kinematic models of the lower limb and by running optimization processes aimed at obtaining estimates of position and orientation of relevant bones...

Tun Hing Lui
The underlying reason for recurrence of hallux valgus deformity after bunion surgery is multifactorial and includes surgeon-based and patient-based factors as well as original components of deformity initially unaddressed at the index procedure. Surgical treatment of a recurred hallux valgus deformity should be undertaken using the same guidelines for correction of a primary hallux valgus deformity. It requires correction of bony alignment, restoration of joint congruity, and achievement of soft tissue balance...

The estimation of joint kinematics from skin markers is hindered by the soft tissue artefact (STA), a well-known phenomenon although not fully characterized. While most assessments of the STA have been performed based on the individual skin markers displacements, recent assessments were based on the marker-cluster geometrical transformations using, e.g., principal component or modal analysis. However, these marker-clusters were generally made of 4-6 markers and the current findings on the STA could have been biased by the limited number of skin makers analysed...

Peptoniphilus asaccharolyticus, a Gram-positive obligatory anaerobic coccus, is a commensal of the human vagina and gut and can be an opportunistic pathogen in immunocompromised patients. It is usually part of polymicrobial anaerobic infections such as skin and soft tissue infections in diabetics, bone and joint infections and surgical site infections; however, infections caused by P. asaccharolyticus in pure culture have been reported as well. Herein, we describe a case of septic arthritis and osteomyelitis caused by P...

OBJECTIVE: Foot osteoarthritis (OA) is very common but underinvestigated musculoskeletal condition and there is little consensus as to common magnetic resonance imaging (MRI) features. The aim of this study was to develop a preliminary foot OA MRI score (FOAMRIS) and evaluate its reliability. METHODS: This preliminary semiquantitative score included the hindfoot, midfoot, and metatarsophalangeal joints. Joints were scored for joint space narrowing (JSN; 0-3), osteophytes (0-3), joint effusion/synovitis, and bone cysts (present/absent)...

Infected nonunions of tibia pose many challenges to the treating surgeon and the patient. Challenges include recalcitrant infection, complex deformities, sclerotic bone ends, large bone gaps, shortening, and joint stiffness. They are easy to diagnose and difficult to treat. The ASAMI classification helps decide treatment. The nonunion severity score proposed by Calori measures many parameters to give a prognosis. The infection severity score uses simple clinical signs to grade severity of infection. This determines number of surgeries and allows choice of hardware, either external or internal for definitive treatment...

The modified Jones procedure is the classic operative treatment of symptomatic clawed hallux. It is composed of transfer of the extensor hallucis longus tendon to the first metatarsal neck and fusion of the hallux interphalangeal joint. The purpose of this technical note is to report the technique of an arthroscopically assisted modified Jones procedure. This can be combined with other minimally invasive bone and soft-tissue procedures to correct all aspects of the complex cavus foot deformity.

BACKGROUND: Fibular hemimelia is the most common deficiency involving the long bones. Paley classification is based on the ankle joint morphology, identifies the basic pathology, and helps in planning the surgical management. Reconstruction surgery encompasses foot deformity correction and limb length equalization. The SUPERankle procedure is a combination of bone and soft tissue procedures that stabilizes the foot and addresses all deformities. METHODS: We retrospectively reviewed 29 consecutive patients (29 limb segments), surgically treated between December 2000 and December 2014...

Shreekant Gupta, Saqib Masud
Hallux rigidus is osteoarthritis affecting the metatarsophalangeal joint of the first toe. Patients often complain of pain and stiffness with pain being aggravated by walking, particularly during toe-off in the gait cycle. Osteoarthritis of the metatarsophalangeal joint is commonly treated with arthrodesis or resection arthroplasty. Metallic replacement of this joint is used sometimes but is not widely accepted. The use of silastic joints has problems with synovitis and implant failure. The authors used titanium implants, which can be screwed into the metatarsal and phalanx, allowing good fixation without the use of bone cement...

REVIEW
Ralph Gaulke, Christian Krettek
Because of the complex fracture morphology and vulnerable soft tissue coverage, fractures of the tibial pilon are difficult to treat. Complications are more common than in bi- or trimalleolar fractures. The surgeon has to know about the special risks of these injuries to avoid complications. Early complications are soft tissue necrosis, persisting fragment dislocations after surgery, loss of reposition and deep wound infection. The surgeon has to be aware of early signs of compartment-syndrome and chronic regional pain syndrome (CRPS)...
