PURPOSE The spontaneous extensor pollicis longus (EPL) tendon rupture is a well-documented complication of non-displaced or minimally displaced distal radius fracture. Authors analyzed the radiographs of patients treated for closed EPL rupture after distal radius fracture. MATERIALS AND METHODS Twenty-eight patients (21 females, 7 males; average age of 58 years) with tendon transfer for spontaneous rupture of EPL after distal radius fracture were included. Wrist radiographs were taken at the first visit with EPL rupture. On the lateral view, posterior cortical displacement, distance from highest point in Lister's tubercle to fracture line, and height of the Lister's tubercle were measured. The distance from the lunate facet to the fracture line was measured on anteroposterior view. Radiologic change at the time of EPL rupture around the Lister's tubercle was evaluated by comparing it with the contra lateral wrist radiograph. Radial beak fracture pattern was also identified. RESULTS The interval between the injury and the spontaneous EPL rupture varied from 2 to 20 weeks, with an average of 6.7 weeks. There were 25 cases of non-displacement, 3 cases of mean 2.0 mm cortical displacement. The average distance from the lunate facet to the fracture line was 9.1 mm (3-12.1 mm), from the highest point in Lister's tubercle to the fracture line was 3.0 mm toward proximal radius (1.7-4.9 mm). The average height of the Lister's tubercle was 3.4 mm in the injured wrist and 3.1 mm in the opposite wrist. Radial beak fracture pattern was shown at 11 cases. CONCLUSION All cases presented no or minimal displaced fracture, and the fracture line was in the vicinity of the Lister's tubercle. Those kinds of fractures can highlight the possibility of spontaneous EPL rupture, depites its rarity.
PURPOSE This study was to assess the morphological changes of the pronator quadratus (PQ) muscle using an ultrasonography in the volar locking plate fixation group and in the percutaneous K-wire fixation group for distal radius fracture, and to evaluate the impact on clinical outcomes. MATERIALS AND METHODS Fifty-four patients who received surgical treatment for distal radius fracture were enrolled in this study. They were divided into two groups according to treatment modality: Group 1 included 34 patients who underwent internal fixation with volar locking plate and Group 2 included 20 patients with percutaneous K-wire fixation. Thickness of the PQ muscle was measured using an ultrasonography at the final follow-up. We evaluated the outcomes using the Mayo wrist score, wrist range of motion, and grip strength at the final follow-up. RESULTS Compared with the uninjured side, thickness of the PQ muscle showed 31.9% of mean atrophy in Group 1 and 11.4% in Group 2. The atrophy of PQ muscle was severe in Group 1 (p=0.01). However, there was no significant difference in the mean Mayo wrist score between the two groups (83.1±10.9 in Group 1 and 80.2±8.9 in Group 2, p=0.28), except a mild limitation of pronation in Group 1. CONCLUSION The healed PQ muscle from fracture itself after distal radius fracture revealed a morphological atrophy. Moreover, the volar locking plate resulted in greater atrophy of the PQ muscle, but there was no specific impact on clinical outcomes.
PURPOSE We evaluated the usefulness of an additional, 2.7 mm mini-locking plate for tibial pilon fractures. MATERIALS AND METHODS We studied 21 patients (14 males and 7 females), who were treated with a 2.7 mm mini-locking plate via the anterolateral approach for tibial pilon fractures between September 2012 and April 2014. The mean age was 43.85 years, and the mean follow-up period was 16.6 months. The radiologic outcomes were graded by the Burwell and Charnley modified system and clinical outcomes were evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score and visual analogue scale (VAS) score. RESULTS The mean union period was 14.3 weeks. At the final follow-up, radiologic results showed 16 excellent results, 4 fair results, and 1 poor result. The average VAS was 3.4 points; the average AOFAS score was 81.8 points. During the follow-up period, there were three cases of posttraumatic osteoarthritis and one case of superficial skin infection. CONCLUSION Additional anterolateral, 2.7 mm mini-locking plate may be a good treatment method to manage tibial pilon fractures.
High-velocity gunshot injury (muzzle velocity greater than 609.6 m/s) is uncommon and primarily a military injury. Humerus shaft fracture, caused by a high-velocity gunshot, should be considered as a severe open fracture. The principles of treatment are immediate and aggressive irrigation, wide debridement, primary delayed wound closure, and broad-spectrum intravenous antibiotics. External fixation has been widely used for fracture fixation. We report a case of humerus shaft fracture secondary to high-velocity gunshot (machine gun) injury, with a literature review.
The management of nonunion with severe bone loss is a challenging task to both surgeons and patients. It often requires prolonged and potentially painful treatments. Moreover, it also represents serious socioeconomic issues for patients. Inadequate fracture stability, disrupted biology, such as blood supply and soft tissue, as well as severe bone loss or presence of infection are possible reasons for nonunion. Several different treatment modalities are available, including nail dynamization, plate osteosynthesis, exchange nailing, and adjuvant alternatives, such as electrical or ultrasound stimulation. Autogenous bone graft remains the standard method to reconstruct small defects. Distraction osteogenesis and induced membrane techniques are contemporary strategies of choice for the reconstruction of larger bony defects. Herein, we attempt to describe the key techniques that may be employed in treating nonunion with severe bone loss.

With an aging population and the development of surgical techniques, there is a growing demand for bone reconstruction in areas of trauma, arthroplasty, and spinal fusion Although autogenous bone grafting may be the best method for stimulating bone repair and regeneration, there are still problems and complications, including morbidity related to bone harvesting and limitation of harvest amount. Allogeneic bone grafts have a limited supply and risk of transmission of infectious diseases. Over the past several decades, the use of bone substitutes, such as calcium phosphate, has increased; however, they have limited indications. Biomedical research has suggested a possibility of stimulating the self-healing mechanism by locally transmitting the external growth factors or stimulating local production through a gene transfer. In this review, we evaluate recent advances, including bone graft, bone substitutes, and tissue engineering.
