ABSTRACT We report a method for removing the distal segment of a broken locked intramedullary nail secondary to nonunion of the femur following radiotherapy for fibromatosis. A Kirschner wire with one tip fashioned into a hook was used to remove the distal segment without opening with the nonunion site. Details of the procedure are described. KEY WORDS Broken intramedullary nail, removal of d...

The editors have also carefully selected additional cases, contributed by several experts in nonunion treatment. Each case provides step-by-step descriptions of case history, preoperative planning, surgical approach, reduction, fixation, rehabilitation, and finally pitfalls and pearls. Hundreds of full-color pictures, precise illustrations, and x-rays demonstrate the significant steps in nonuni...

OBJECTIVE Nonunion is defined as a minimum of a 9-month period of time since an injury with no visibly progressive signs of healing for 3 months. Recent studies show that application of mesenchymal stromal cells (MSCs) in the laboratory setting is effective for bone regeneration. Animal studies have shown that MSCs can be used to treat nonunions. For the first time in an Iranian population, the...

PURPOSE To examine potential risk factors for the development of delayed or nonunion following elective ulnar shortening osteotomy using a dedicated osteotomy plating system. METHODS We performed a retrospective review of all patients who underwent elective ulnar shortening using the TriMed single osteotomy dynamic compression plating system by 1 of 2 fellowship-trained hand surgeons over a 5...

Nonunion fractures can cause severe dysfunction and are often difficult to treat mainly due to a poor understanding of their physiopathology. Although many aspects of impaired fracture healing have been extensively studied, little is known about the cellular and molecular mechanisms leading to atrophic nonunion. Therefore, the aim of the present study was to assess the pools and biological func...

Introduction Isolated, neglected medial malleolus nonunion cases are a rare entity in orthopedic literature. All studies (except one) have described the use of compression screws (with or without plates) for medial malleolar nonunion management. In acute fractures, tension band wiring (TBW) has shown excellent results both in biomechanical and in clinical studies. On the contrary, it has seldom...

We have investigated whether assessment of blood flow to the proximal scaphoid can be used to predict nonunion in acute fractures of the scaphoid. We studied 32 fractures of the scaphoid one to two weeks after injury, by dynamic fat-suppressed T1-weighted gradient-echo MRI after the intravenous administration of gadopentetate dimeglumine (0.1 mmol/kg body-weight). Steepest slope values (SSV) an...

Background: Non-united fracture shaft of the femur after plate fixation is a common problem. Management this problem still controversial. There are many methods for treating femoral aseptic nonunions with broken implant which conversion to reaming solid intramedullary nail one procedures. However, reported success rate varies. This study aimed evaluate bone healing, especially callus formation,...

Bone grafting is one of the most common orthopedic procedures. We conducted a study to assess the possibility of passing a Reamer/Irrigator/Aspirator (RIA; DePuy Synthes) retrograde through the nonunion site in distal femur cases. This technique would avoid the complications and discomfort associated with a separate entry site for RIA. All patients with a distal femur nonunion treated with RIA ...
