BACKGROUND Trochanteric fractures (TF) have become a major source of morbidity and mortality in elderly. We conducted this study to compare the outcomes of unstable trochanteric fractures treated with the InterTan nail and Gamma3 nail. METHODS Between January 2008 and May 2013, patients aged 60 years or older with a diagnosis of unstable TF treated with InterTan nail or Gamma3 nail were inclu...

BACKGROUND Knee or tibiotalocalcaneal arthrodesis is a salvage procedure, often with unacceptable rates of nonunion. Basic science of fracture healing suggests that compression across a fusion site may decrease nonunion. A novel ratcheting arthrodesis nail designed to improve dynamic compression is mechanically tested in comparison to existing nails. METHODS A novel ratcheting nail was design...

Melanonychia, or melanin-derived brown-to-black nail pigmentation, is a diagnostic challenge for clinicians. The most serious disease of the nail unit, melanoma, primarily presents with melanonychia. However, melanonychia most often occurs as a result of benign etiologies such as nail matrix melanocytic activation, nail matrix melanocytic hyperplasia, and nail invasion by melanin-producing path...

Full article available online at Healio.com/Orthopedics. Search: 20140225-52 Chronic anterior knee pain is the most common complication after tibial nail insertion. Its etiology remains unknown, and multifactorial sources have been suggested. The authors believe that nail prominence and the insertion point of the nail are important in the development of anterior knee pain. The purpose of this r...

This article presents new intramedullary (IM) nail design for femur diaphyseal fractures osteosynthesis. Biomechanical comparison of the two IM nails (standard locking and new developed) was conducted. Femur medullary canal architectonics was studied with the help of computer tomography (CT) data. Three-dimensional (3D) models of the femur, its transverse fracture, standard locking nail and new...

OBJECTIVE to analyze the results from surgical intervention to treat trauma of the nail complex. METHODS we retrospectively reviewed a series of 94 consecutive patients with trauma of the nail complex who were treated between 2000 and 2009. In 42 patients, nail bed suturing was performed. In 27 patients, nail bed suturing was performed subsequent to osteosynthesis of the distal phalanx. In 15...

Nail abnormalities occur frequently in patients with psoriatic arthritis. This study of the finger nails of 46 patients with psoriatic arthritis, 100 nonpsoriatic rheumatism patients, and 100 nonpsoriatic general medical patients was designed to characterise these abnormalities with particular reference to the severity of nail pitting. The results of the study suggest: (1) Onycholysis alone in ...

Onychomadesis usually arises from an inflammation of the paronychium or as a result of blisters and hemorrhaging under a nail that has been struck or compressed. No documented interactions between basic fibroblast growth factor (bFGF) and onychomadesis have hitherto been reported. This case report describes a 25-year-old woman with onychomadesis following infection of the ingrown nail of her le...

Nail guns are potentially lethal tools that fire nails in rapid succession at high velocity. The nail cartridges are held together with wire, plastic, glue, tape, or paper. When wire is used, the 2 carrier wires (Figure 1) are called the wire collation. As the nail is fired, these 2 wires are sheared off, leaving 2 barblike pieces of wire ( 6 mm) attached to the nail. The 2 pieces are then shea...
