INTRODUCTION: Extremely heterogeneous revision rates in total ankle arthroplasty (TAA) of the upper ankle joint are reported and result to heterogeneous collectives and to short follow-up times. The aim is to investigate revision rates and the underlying reasons, as well as treatment outcome and quality of life after TAA in post-traumatic cases with sufficient follow-up. METHODS: In 2008-2013, 74 patients with post-traumatic arthrosis were treated using TAA with a Tornier Salto prosthesis, and 60 (35 males and 25 females; mean age 56) were followed-up (mean: 59 months; range 24-91 months)...

Bone cement spacers loaded with antibiotic are the gold standard in septic revision. However, the management of massive bone defects constitutes a surgical challenge, requiring the use of different nails, expensive long stems, or cement-coated tumor prostheses for preparing the spacer. In most cases, the knee joint must be sacrificed. We describe a novel technique for preparing a biarticular total femur spacer with the help of a trochanteric nail coated with antibiotic loaded cement, allowing mobility of the hip and knee joints and assisted partial loading until second step surgery...

A good long-term outcome following a total knee arthroplasty relies on restoration of the mechanical axis and effective soft tissue balancing of the prosthetic knee. Arthroplasty surgery in patients with secondary osteoarthritis of the knee with an extra-articular tibial deformity is a complex and challenging procedure. The correction of mal-alignment of the mechanical axis is associated with unpredictable result and with higher revision rates. Single-staged deformity correction and replacement surgery often result in the use of constraint implants...

The present study reports a rare case of radiation recall pneumonitis attributed to ifosfamide that was used as a single antitumor agent for a recurrent malignant soft tissue tumor, arising from the chest wall. A 74-year-old man, who had a mass in his right upper chest wall, underwent surgical excision under the diagnosis of chronic expanding hematoma. He was referred to the present hospital with a recurrent tumor as the excised tumor was diagnosed as undifferentiated high-grade sarcoma. The extension of the tumor following previous surgery was aggressive and the tumor margins were unclear on magnetic resonance imaging...

The principles of open fracture management are to manage the overall injury and specifically prevent primary contamination becoming frank infection. The surgical management of these complex injuries includes debridement & lavage of the open wound with combined bony and soft tissue reconstruction. Good results depend on early high quality definitive surgery usually with early stable internal fixation and associated soft tissue repair. While all elements of the surgical principles are very important and depend on each other for overall success the most critical element appears to be achieving very early healthy soft tissue cover...

BACKGROUND: Muscle flap is a valuable option in soft tissue reconstruction. Denervated skeletal muscle is known to undergo degeneration. However, information regarding histological and genetic changes in muscle free flap without reinnervation over long-term follow-up remains unclear. METHODS: We collected flap muscles obtained during secondary exploration surgery after more than 15 years of previous muscle free flap without reinnervation. Compared with normal muscle and fat, histomorphometric and gene expression analysis of flap muscle were performed...

Multiphoton microscopy has been widely adapted for imaging neurons in vivo. Repeated imaging requires implantation of a cranial window or repeated thinning of the skull. Cranial window surgery is typically performed with a high speed rotary drill, and many investigators find it challenging to prevent the drill from damaging the delicate dura and blood vessels. Extensive training and practice is required to remove the bone without damage to underlying tissue and thus cranial window surgery can be difficult, time consuming, and produce tissue damage...

Mandibular osteotomy carries with it a risk of damaging blood vessels and nerves when using traditional surgical techniques. Piezosurgery® , is a new technique that uses ultrasonic vibration to enable bone-selective sectioning without damage to the surrounding soft tissues. However, paralysis may not be completely eliminated using Piezosurgery® for osteotomy. We investigated how piezoelectric surgery in bilateral sagittal splitting ramus osteotomy (BSSRO) affected the surrounding soft tissue. Forty-four patients with skeletal mandibular prognathism underwent mandibular setback with BSSRO...

Soft tissue impingements are well-known complications of total knee arthroplasty. The impingements usually occur between the medial or lateral femoral component and tibial insert, and between the patella and femoral components. We report a rare case of impingement of the soft tissue between the femoral intercondylar fossa and post of the polyethylene insert, which caused pain and walking disability. After the surgery for the arthroscopic removal of the soft tissue, the symptoms disappeared. However, prosthetic loosening of the femur occurred several months after the arthroscopic surgery, requiring revision surgery...

Post-traumatic peroneal tendon subluxation or dislocation is most commonly due to injury to the superior peroneal retinaculum. Acute repair of the retinaculum is an option for active athletes who desire quick return of sport activity. In general, conventional open surgeries require extensive exposure of the injured superficial peroneal retinaculum and have potential risks of scar formation, sural nerve injury, limited range of movement, peroneal tendon re-subluxation, and tendon irritation. The purpose of this Technical Note is to describe the details of endoscopic superior peroneal retinaculum reconstruction...

The field of periodontal plastic surgery is always a subject of fascination for periodontists, and the importance of pink esthetics is gaining its pace. Preservation of what is existing is more important than its replacement. The same principle also applies to soft-tissue esthetic procedures thereby the concept of minimal surgical invasion came into existence. This article presents a series of five cases with 18 recession sites which were treated with a minimally invasive Pinhole Surgical Technique which resulted in overall root coverage of 96...

BACKGROUND: Retroperitoneal or mesenteric primary liposarcoma is a malignant neoplasia whose prognosis depends on the biological variants, the radical resection surgery and the histological subtypes, as well as on local and remote recurrences. Liposarcoma is the most common variant of this tumour among tumours of soft retroperitoneal tissue. The purpose of this study is to evaluate whether the treatment of this disease, carried out at the Ivrea Hospital for urgent reasons, may be considered in line with the experience of high-volume Centres...
