Harrington instrumentation as a method of fixation in fractures of the spine.

The results of the use of Harrington rods in the treatment of spinal fractures were reviewed. It was found that with burst fractures where the anterior pillar was deficient there was a significant incidence of loss of reduction. Anterior bone supplementation is recommended in these fractures when major loss of height or angulation occurs. Several technical faults were detected which, in most cases, also led to a loss of reduction. Almost all patients with an anatomical reduction were free of pain. There was no correlation between the loss of reduction and the lapse of time before operation, the levels of instrumentation, the length of the fusion, the severity of the initial deformity, the degree of initial correction or the presence or absence of a neurological deficit.

External fixation in comminuted upper femoral fractures.

External fixation of comminuted upper femoral fractures has not been studied widely. The minority of such fractures which cannot be fixed internally due to clinical and anatomical problems are generally treated in traction. Early external fixators were not sufficiently robust to hold these fractures and pin site problems are more common in femoral fixation than in the tibia. A study was undertaken including all patients with comminuted upper femoral fractures who were too unwell or otherwise unsuitable for internal fixation. The long-term results were comparable, if not superior to traction, and patient comfort and mobilization were much improved.

Tension band wiring for fixation of comminuted fractures of the distal radius.

In the treatment of unstable comminuted and intra-articular fractures of the lower end of the radius, we have found that is is essential to reconstitute the normal anatomical relationship of the radius to the carpus and to the ulna. This is possible by performing an open reduction and by maintaining the fractured fragments by Kirschner wires and adding a tension band. Patients treated thus are reported. There have been no complications and the patients regained full function of the wrist without unsightly deformity.

Pin reduction and fixation of volar fracture fragments of distal radius fractures via the flexor carpi radialis tendon.

BACKGROUND: The objective of this study was to evaluate a technique for reduction and stabilization of residually displaced volar fragments in intraarticular distal radius fractures. METHODS: A consecutive series of patients with AO type C3 distal radius fractures treated by one surgeon were studied. Percutaneously placed pins were placed through the flexor carpi radialis tendon to reduce and stabilize volar fracture fragments of distal radius fractures when closed reduction was unsuccessful. The goal of treatment was to achieve less than 2 mm of articular congruity. Postoperative physiotherapy was protocol-based. A validated outcome measurement was used to evaluate patients. RESULTS: Of 117 patients, 10 met the inclusion criteria. In all patients, a successful reduction of the volar fragment was achieved with less than 2 mm of residual articular step-off. Reduction was maintained in 8 patients. Follow-up averaged 29 months, and there were no complications associated with the technique. All patients were satisfied with the treatment. CONCLUSION: Although the final outcome of patients with this type of fracture depends on many factors, in the small series of patients described, a satisfactory reduction was possible using the describe technique. Transtendinous pinning is a new, undescribed technique that is useful in the treatment of such specific injuries.

Internal fixation of diaphyseal fractures of the forearm by interlocking intramedullary nail: short-term results in eighteen patients.

OBJECTIVE: This study was designed to evaluate the efficacy of the treatment of diaphyseal fractures of the forearm using the ForeSight forearm interlocking intramedullary nail. DESIGN: Retrospective study. SETTING: University-affiliated teaching hospital. PATIENTS: Eighteen patients with 32 displaced diaphyseal forearm fractures were identified. INTERVENTION: All fractures were treated with the ForeSight forearm interlocking intramedullary nail. Eighteen fractures were stabilized with static interlocking technique. MAIN OUTCOME MEASURES: The assessment of patients was based on the time to union, the functional recovery, and the incidence of complications. Physical capability was evaluated by using the rating system of Grace and Eversmann. Patient-rated outcome was assessed by completion of the Disability of Arm Shoulder Hand questionnaire (DASH). RESULTS: All fractures healed with the index procedure. The average time to union for fractures utilizing a closed technique was 10 weeks; for fractures using an open reduction technique, 15 weeks. The mean pronation was 62 (range, 0-96) degrees, and the mean supination was 80 (range, 0-105) degrees. Compared with the normal arm, the mean loss of rotation of the forearm was 32 (range, 5-162) degrees. Using the rating system of Grace and Eversmann, 13 patients had an excellent or good result, 3 had an acceptable result, and 2 had an unacceptable result. Using the patient-rated functional questionnaire, the mean DASH of 19 (range, 4-72) points at the time of the most recent follow-up indicated a mild-to-moderate impairment. There were 7 postoperative complications. The incidence of complications was 22% (7/32). One cross-union between forearm bones occurred in a patient with a closed head injury and high-energy trauma. Two nondriving end screws of the ulna nail backed out causing wrist pain and had to be removed. There were 4 superficial infections occurring all in the fractures that necessitated an open reduction technique. The overall rate of infection was 12.5% (4/32). Three patients who presented with an open fracture needed a skin graft to cover the open wound. CONCLUSIONS: Forearm interlocking intramedullary nailing is an acceptable method to stabilize displaced diaphyseal forearm fractures in adult.

Posterior cervical fixation for fracture and degenerative disc disease.

There are numerous newer techniques that have been developed for the internal fixation of the cervical spine in recent years. Wiring techniques are still appropriate for posterior stabilization of the cervical spine. The halo vest is still widely used for the conservative management of cervical fractures and for postoperative external immobilization. The authors stress that the surgical indications for more modern rigid implants should be adhered to strictly. These implants also should be selected by weighing their advantages versus potential risks. In the upper cervical spine, the surgeon may choose traditional wiring methods and newer C1-C2 screw fixation, occipitocervical plate fixation. For the lower cervical spine, triple wiring technique or lateral mass plating may be used. The surgeon must choose an appropriate device based on the mechanism of injury, pathoanatomy of the lesion, and familiarity with the device, keeping in mind that the goals of internal fixation are stabilization, reduction and maintenance of alignment, early rehabilitation and perhaps enhancement of fusion rates, and avoidance of use of an external halo vest.

[Angle- and rotation-stable internal fixation of proximal humerus fractures with the humerus fixator plate. Early clinical experience with a newly developed implant].

INTRODUCTION: The Humerus Fixator Plate is presented as a new implant for angle- and rotation-stable internal fixation for the operative treatment of proximal humerus fractures at the surgical neck. METHODS: In an ongoing two-centre study, 47 patients were treated with the new implant. To date, 31 patients had clinical and radiological postoperative follow-up examinations with a mean interval of 10 months (range: 6-14 months). RESULTS: In 46 patients (97.9%), complete angle and rotational stability was achieved without limiting the range of motion or requiring immobilization. Good pain relief was obtained in 43 patients (91.5 %), and 3 patients (6.4%) showed moderate pain relief following surgery. There was one implant failure. Utilizing the Constant-Raw score (without any correction factors), a mean result of 82.8 points (range: 46-100 points) was ascertained. The majority of the patients (87.1%) achieved "excellent" or "good" clinical results. X-ray analysis revealed no non-union nor humerus head necrosis. In 4 cases (12.9%), protrusion of a humerus head screw was observed which mandated removal of the implant. CONCLUSION: The first clinical investigations of the novel Humerus Fixator Plate are encouraging and provide essential advances in the treatment of unstable proximal humerus fractures.

Anatomy of the superficial peroneal nerve in relation to fixation of tibia fractures with the less invasive stabilization system.

OBJECTIVE: To examine the danger to the superficial peroneal nerve during percutaneous screw placement in the distal holes of the 13-hole proximal tibia Less Invasive Stabilization System plate in a cadaver. DESIGN: Anatomic study. SETTING: Medical school anatomy laboratory. INTERVENTIONS: Fourteen adult cadaveric lower extremities were used. A 13-hole proximal tibia Less Invasive Stabilization System plate was placed as described by the manufacturer. Dissection of the superficial peroneal nerve was performed following localization of screw holes 7 through 13 using insertion sleeves, centering sleeves, and 2.0-mm Kirschner wires passed through the insertion guide. RESULTS: The average distance from the superficial peroneal nerve to the center of holes 11, 12, and 13 was 10.0 mm (range 0-21, standard deviation 5.6), 6.8 mm (range 0-16, standard deviation 4.3), and 2.7 mm (0-11, standard deviation 3.7), respectively. In 12 of 14 legs (86%), the superficial peroneal nerve was 5.0 mm or less from the center of hole 13. The nerve was touching the guide wire at hole 11 in 1 specimen (7%), at hole 12 in 2 specimens (14%), and at hole 13 in 6 specimens (43%). In 1 specimen (7%), the guide wire pierced the superficial peroneal nerve at hole 13. CONCLUSION: These findings suggest that the superficial peroneal nerve is at significant risk during percutaneous screw placement in holes 11 through 13 of the 13-hole proximal tibia Less Invasive Stabilization System plate. Use of a larger incision and careful dissection down to the plate in this region may minimize the risk of damage to the nerve.

Anterior screw fixation of odontoid fractures.

BACKGROUND: Anterior screw fixation is the best treatment for odontoid fractures when the fracture line is horizontal or oblique downward and backward, as it preserves atlantoaxial mobility, especially axial rotation. Some details regarding patient positioning and operative technique need to be stressed to obtain the best results and avoid complications. METHODS: Between 1989 and 1997, we treated 17 cases of odontoid fracture by anterior screw fixation. Only two patients presented with motor neurologic deficit. Fracture line was horizontal in 3 cases and oblique downward and backward in 14 cases. RESULTS: Adequate reduction and fixation was obtained in all cases except one, where posterior displacement of the screw occurred without neurologic complications. Functional result was satisfactory in all cases except two, where we noted significant limitation of cervical rotation. CONCLUSION: Successful anterior screw fixation gives the best anatomical and functional results for odontoid fractures. Correct installation is very important for operative success.
