Background: Psychosocial factors, such as depression and catastrophic thinking, might account for more disability after various orthopaedic trauma pathologies than range of motion and other impairments. However, little is known about the influence of psychosocial aspects of illness on long-term symptoms and limitations of patients with rotational-type ankle fractures, including a posterior malleolar fragment. Knowledge of the psychosocial factors associated with long-term outcome after operative treatment of trimalleolar ankle fractures might improve recovery. Read More

The cornerstones for treatment of articular fractures are gentle handling of soft tissues and anatomical reconstruction of the articular surface with stable fixation, which enables a functional aftercare. By respecting these principles, satisfactory functional and radiological results with low complication rates can be achieved even for complex fracture patterns. Fracture complexity varies with the energy load during the trauma mechanism. Read More

Orthotrauma Research Center, University of Amsterdam Orthopaedic Residency Program (PGY 4), Amsterdam, The Netherlands.

Background: In some settings, specific techniques for open reduction and internal fixation are preferred based on the eminence of a surgeon or professional organization. An emphasis on technical aspects of surgery that are not proved superior and vary substantially from surgeon to surgeon can be confusing for trainees. This study applied a numerical grading of the technical aspects of tension band wire (TBW) fixation for olecranon fracture; assessed the interobserver agreement of each criterion; and measured the correlation of the technical grading and objective and subjective long-term outcomes.

The extent to which data from immunohistochemical (IHC) staining are useful is critically dependent not only upon the proper performance and control of the method but also upon appropriate interpretation. A decade ago an individual pathologist may have nurtured a reasonable expectation of achieving a comprehensive understanding of the IHC literature across the whole field of pathology. Today such an expectation is clearly unreasonable with a simple Medline search of the IHC literature postdating the general adoption of antigen retrieval (arbitrarily 1996), yielding more than 100,000 "relevant" articles.

Zygomatic arch fractures are common injuries, occurring in isolation in 5% of all patients with facial fractures and in 10% of patients with any fracture to the zygomaticomaxillary complex. Isolated noncomminuted depressed zygomatic arch fractures are easily treated with the minimally invasive Gillies approach, which most often provides long-term stability. However, zygomatic arch fractures often occur in conjunction with zygomaticomaxillary complex, Le Fort, calvarial, and naso-orbitoethmoid fractures. Read More

This article describes the cases of 3 patients who were treated for impending pathologic fractures with intramedullary stabilization who developed soft tissue tumor recurrence along the surgical tract site postoperatively, with confirmed histologic diagnoses consistent with each of their prior-known metastatic primaries. This sequela of treatment can lead to additional surgical procedures, longer recovery, and a delay in further systemic treatment, which negatively affects patient outcomes and survival. This can occur despite the use of adjuvant radiation therapy to the surgical site. Read More

Although definitive fixation of anterior pelvic ring injuries is usually referred to an orthopaedic trauma surgeon or a surgeon proficient in pelvic surgery, all orthopaedic surgeons should be familiar with the initial management and resuscitation of patients with high-energy pelvic ring injuries. The initial treatment may be limited to sheet or binder application in the emergency department to allow transfer of the patient to a trauma center or the application of an external fixator by an on-call surgeon, even though that surgeon may not be responsible for definitive fixation. It is important to understand the general principles and approaches used at the time of definitive surgery because decisions made by the initial treating physician may affect (or limit) the ability of the orthopaedic traumatologist to provide definitive care.

The treatment of pediatric facial fractures, although similar to that of adults, requires a separate and thorough understanding of the unique developmental issues inherent to this age group. The contribution of several of these factors allows for a large portion of these injuries to be managed more conservatively; however, operative indications still exist. The optimal form of management in these situations must balance the risks of impacting dentition or future skeletal growth versus obtaining acceptable stability and reduction for healing. Read More

Although reamed intramedullary nailing has long been considered a safe procedure, pulmonary complications have been reported in some groups of patients. Concerns over fat embolisation, adult respiratory distress syndrome (ARDS), and sudden intraoperative death have prompted some authors to question whether the benefits of reaming are outweighed by its potential adverse effects to the patient. In response to these complications, recent evaluations have focused on alternative systems that reduce intramedullary pressure during reaming. Read More

Introduction: Nonunion of pertrochanteric fracture is rare and its occurrence especially without prior surgical intervention has been hardly ever reported. Hence there is not much literature describing the best way to treat them. Nonunion of pertrochanteric fracture collapses in to varus by virtue of deforming action of muscles and thus deranging the biomechanics of the hip and indirectly preventing fracture union further.

The basic principles of an internal fixation procedure using a conventional plate and screw system (compression method) are direct, anatomical reduction and stable internal fixation of the fracture. Wide exposure of the bone is usually necessary to gain access to and provide good visibility of the fracture zone to allow reduction and plate fixation to be performed. This procedure requires pre-contouring of the plate to match the anatomy of the bone. Read More
