Impact of external fixation on adolescents: an integrative research review.

PURPOSE: To define the state of nursing knowledge about the psychological impact of treating adolescents with external fixation devices (EFDs). METHOD: An integrated research review was conducted on literature available from CINAHL, MEDLINE, and PsycINFO. Keywords used were external fixation, fracture fixation, orthopaedic or orthopaedic, limb lengthening, Ilizarov, halo traction, Orthofix, EBI fixator, pelvic fixator, ring fixator, body image, self-concept, self-esteem, self-perception, adaptation, emotional, behavior, and outcome. Inclusion criteria for studies were (a) publication from 1990 to 2003, (b) focus on psychosocial and functional outcomes of treating adolescents with EFDs, and (c) publication in English. Studies were categorized by author, year, discipline(s), design, focus, sample, measurement, findings, and research recommendations. Findings and recommendations were compared across publications. RESULTS: All studies reported psychological and behavioral changes after EFD treatment. Pain and pin-site infections were the most problematic physical findings. Depression was universally evident to varying degrees, with some suicidal ideation and self-destructive behaviors, although mostly reported as transient. This predominantly retrospective cohort of studies reported social isolation as well as eating and sleep disturbances. Family and nursing support, a multiple disciplinary approach, and better preoperative preparation were crucial to adolescents psychological health after EFD treatment. CONCLUSION: Adolescents treated with EFDs require significant psychosocial support. The findings reveal major gaps in the knowledge on adolescents treated with external fixation for traumatic injury and none focused on EFD treatment in the acute period.

Screw fixation of odontoid fractures and nonunions.

Surgical treatment of odontoid fractures has usually been carried out by C1-2 arthrodesis rather than by fracture fixation. An alternative treatment of compression screw fixation was used to treat selected acute odontoid fractures and nonunions. Ten patients were operated on. A variety of lag-screw types were used to compress and secure the fracture. Screw placement was considered excellent in five cases; in four, the screw tip protruded through the posterosuperior cortex of the dens by 1-3 mm. One patient died as a result of multiple injuries 2 days after surgery. In all other cases, including four cases of odontoid pseudarthroses, the fractures achieved solid union. It was concluded that screw fixation can be used for the successful treatment of selected odontoid fractures and nonunions.

Intramedullary versus extramedullary fixation of subtrochanteric fractures. A biomechanical study.

We compared two different subtrochanteric fracture fixation techniques, an intramedullary hip screw system (IMHS) and an extramedullary, dual sliding screw-plate system (MSP), to determine relative fixation stability. 6 matched pairs of osteosynthesized osteopenic cadaver femurs were axially loaded to 1000 N with concurrent, simulated abductor forces of 0%, 50%, or 86% of the applied head force. The initial loading sequence was made with uniaxial dynamization--the lag screw of the MSP locked and distal locking of the IMHS nail. Femoral head displacement and medial femoral strain were measured for intact femur controls, after fixation of a 2-part reverse oblique subtrochanteric fracture and finally a 3-part reverse oblique subtrochanteric fracture with a lateral wedge defect. The samples were then loaded at 750 N for 10(4) cycles with both devices uniaxially locked, followed by 10(4) cycles with both devices fully biaxially dynamized (unlocked). For the 2-part subtrochanteric fracture pattern, both devices exhibited similar inferior displacements of the femoral head (average 2.0 mm) and medial femoral strain (approximately 70% of intact). Increasing abductor forces decreased medial compressive strain but did not significantly affect head displacement. For the 3-part fracture model, the MSP demonstrated significantly less inferior displacement of the head (1.6 mm vs. 2.1 mm) and both devices demonstrated significantly decreased medial strain. After cycling, head displacement increased approximately 50% in both devices and medial strain increased slightly. After unlocking and cycling, the MSP group showed significant lateral displacement of the proximal fragment. The IMHS and MSP devices provide similar stability for fixation of 2-part and 3-part reverse oblique subtrochanteric fractures. In a biaxially dynamized, 3-part reverse oblique fracture, displacement of the proximal fragment can occur with the MSP.

Stress-riser fractures of the hip after sliding screw plate fixation.

Fractures occurring after fixation of intertrochanteric femur fractures have been described previously in the literature. Terms such as "stress-riser fracture" and "Young's modulus fracture" have been applied. The prevalence of these fracture types has increased, and so has use of the sliding screw plate device for fixation of intertrochanteric hip fractures. The object of this paper is to describe, by case examples, types of stress-related fractures of the proximal femur in association with the sliding screw plate and to define each biomechanical type in review.

Does early fixation of fractures reduce mortality in severely injured patients?

It is commonly believed that fixation of fractures as soon as possible after injury reduces mortality and the incidence of pulmonary complications. This belief is supported by a large number of published studies. An audit of 200 patients with severe, multiple injuries performed at the Birmingham Accident Hospital demonstrated that mortality was not influenced by the method of fracture management. The literature relating fracture management to mortality and the incidence of pulmonary complications is critically reviewed and alternative explanations for the apparent benefits of early fracture fixation are discussed. It may be concluded that for patients with severe, multiple injuries which include fractures, early fracture fixation may not be helpful and in certain cases may even be harmful. Although patients undergoing early fracture fixation appear to do better in many institutions, the key feature producing this beneficial outcome may be prompt and accurate resuscitation followed by sophisticated monitoring permitting early detection and prompt treatment of hypoxia and hypovolaemia.

A prospective controlled trial of valgus osteotomy in the fixation of unstable pertrochanteric fractures of the femur.

A total of 62 patients with unstable pertrochanteric fractures of the neck of the femur was subjected to either nail plating with 130 degrees neck-shaft angle or valgus osteotomy using a neck-shaft angle of at least 140 degrees. The patients were assessed in terms of ability to walk and stability of fracture fixation. A clear superiority of valgus osteotomy over the controls was demonstrated in terms of fracture fixation, but the difference in terms of ability to walk was less remarkable.

Fixation of mandibular angle fractures with a 2.0-mm 3-dimensional curved angle strut plate.

PURPOSE: The aim of this study was to evaluate our experience and complication rate with the use of a 3-dimensional 2.0-mm curved angle strut plate for mandibular angle fracture fixation. PATIENTS AND METHODS: This was a retrospective evaluation of 37 patients with noncomminuted mandibular angle fractures fixated with a transorally placed curved 2.0-mm strut plate. Postoperative intermaxillary fixation was used in 5 patients for a mean period of 22 days. A nonchewing diet was prescribed for 6 weeks. Records were reviewed for demographic information, medical history, fracture characteristics, operative management, and complications. RESULTS: Two patients developed infections requiring plate removal and reapplication of fixation. Both of these patients had a molar in the fracture line that was left in place during the first operation. One patient developed a mucosal wound dehiscence without consequence. After a mean follow-up period of 10 weeks, 39.4% of patients with a postinjury/pretreatment inferior alveolar nerve deficit reported a return to normal sensation. All patients who developed a sensory deficit as a result of surgery reported full recovery of sensation. A persistent sensory deficit appeared to be related to fracture displacement. CONCLUSION: Fixation of noncomminuted mandibular angle fractures with a 2.0-mm curved angle strut plate was predictable. This plate is low in profile, strong yet malleable, facilitating reduction and stabilization at both the superior and inferior borders. Development of a postoperative infection appeared to be related to failure of removal of a molar in the fracture line. The infection rate of 5.4% found in this study compares favorably with that seen with reconstruction plates. Use of this plate did not appear to cause a permanent sensory deficit in this study.
