Comparison of low, multidirectional locked nailing and plating in the treatment of distal tibial metadiaphyseal fractures.

PURPOSE: The aim of this study was to compare the results of a new technique for low, multidirectional locked nailing with closed reduction and minimally invasive plating in the treatment of distal tibial metadiaphyseal fractures. METHODS: Forty-six matched patients were divided according to age, gender, Injury Severity Score, and fracture pattern into group A (expert tibial nailing) and group B (minimally invasive plating). Then, the patients were followed up, and the clinical and radiographic results were retrospectively analysed. RESULTS: The mean followed-up was 24.7±2.7 months in group A and 25.8±2.8 months in group B. No patient had nonunion, shortening, hardware breakdown, or deep-seated infection. Patients in group A had a significantly shorter mean operating time, hospital stay, full weight-bearing time and union time (76±16.6 vs. 90±20.3 minutes, p=0.000; 5.8±2.1 vs. 8.9±3.1 days, p=0.000; 9.0±1.4 vs. 11.1±1.7 weeks, p=0.000; and 21.3±3.5 vs. 23.1±3.6 weeks, p=0.047, respectively). Three patients in group A and one patient in group B presented with malalignment (p=0.608). The mean Olerud-Molander Ankle score was 89.0±7.1 in group A and 87.6±8.4 in group B (p=0.478). CONCLUSIONS: Distal tibia metadiaphyseal fractures may be treated successfully with low, multidirectional locked nails or plates. However, low, multidirectional locked nailing may represent a superior surgical option, since it offers advantages in terms of mean operating time, hospital stay, full weight-bearing time and union time.

Novel use of gamma correction for precise (99m)Tc-HDP pinhole bone scan diagnosis and classification of knee occult fractures.

OBJECTIVE: The aim of this study was to introduce gamma correction pinhole bone scan (GCPBS) to depict specific signs of knee occult fractures (OF) on (99m)Tc-hydroxydiphosphonate (HDP) scan. MATERIALS AND METHODS: Thirty-six cases of six different types of knee OF in 27 consecutive patients (male = 20, female = 7, and age = 18-86 years) were enrolled. The diagnosis was made on the basis of a history of acute or subacute knee trauma, local pain, tenderness, cutaneous injury, negative conventional radiography, and positive magnetic resonance imaging (MRI). Because of the impracticability of histological verification of individual OF, MRI was utilized as a gold standard of diagnosis and classification. All patients had (99m)Tc-HDP bone scanning and supplementary GCPBS. GCPBS signs were correlated and compared with those of MRI. The efficacy of gamma correction of ordinary parallel collimator and pinhole collimator scans were collated. RESULTS: Gamma correction pinhole bone scan depicted the signs characteristic of six different types of OF. They were well defined stuffed globular tracer uptake in geographic I fractures (n = 9), block-like uptake in geographic II fractures (n = 7), simple or branching linear uptake in linear cancellous fractures (n = 4), compression in impacted fractures (n = 2), stippled-serpentine uptake in reticular fractures (n = 11), and irregular subcortical uptake in osteochondral fractures (n = 3). All fractures were equally well or more distinctly depicted on GCPBS than on MRI except geographic II fracture, the details of which were not appreciated on GCPBS. Parallel collimator scan also yielded to gamma correction, but the results were inferior to those of the pinhole scan. CONCLUSIONS: Gamma correction pinhole bone scan can depict the specific diagnostic signs in six different types of knee occult fractures. The specific diagnostic capability along with the lower cost and wider global availability of bone scanning would make GCPBS an effective alternative.

[Diagnostics of septic complications after long tubular bones fractures].

Interleukine (IL-1alpha, IL-4) blood levels and lipid peroxidation--antioxidant agents were assessed in 98 patients with fractures of long tubular bones. Using the data, an algorithm was worked out, which permits prediction of septic complications with a high level of accuracy.

Minimally invasive treatment of pilon fractures with a low profile plate: preliminary results in 17 cases.

OBJECTIVE: To determine the results of "biologic fixation" with a minimally invasive plating technique using a newly designed low profile "Scallop" plate in the treatment of pilon fractures. DESIGN: Retrospective case series. SETTING: A tertiary referral center. PATIENTS/PARTICIPANTS: Seventeen patients were treated between 1999 and 2001 for a tibial plafond fracture at the Hospital for Special Surgery with a newly designed low-profile plate. Eleven of the fractures (65%) were high-energy injuries. Two fractures were open. INTERVENTION: Staged surgical treatment with open reduction and fixation of the fibular fracture and application of an external fixator was performed in 12 cases. As soon as the soft tissues and swelling allowed, i.e. skin wrinkling, the articular surface was reconstructed and simply reduced, if necessary through an small incision, and the articular block was fixed to the diaphysis using a medially placed, percutaneously introduced flat scallop plate. In the remaining five cases the operation was performed in one session. MAIN OUTCOME MEASUREMENTS: Time to healing and complications including delayed union, non-union, instrument failure, loss of fixation, infection, quality of reduction and number of reoperations were evaluated. Quality of results and outcome were graded using the ankle-hindfoot-scale and a modified rating system. RESULTS: All patients went on to bony union at an average time of 14 weeks. There were no plate failures or loss of fixation/reduction. Two superficial wound-healing problems resolved with local wound care. At an average follow up of 17 months (range 6-29 months) eight patients (47%) had an excellent result; seven (41%) had a fair result whereas two (12%) had a poor result. The average ankle-hindfoot-score was 86.1 (range 61-100). Four patients have had the hardware removed and one of them is awaiting an ankle arthrodesis. CONCLUSIONS: Based on these initial results, it appears that a minimally invasive surgical technique including new low profile plate can decrease soft tissue problems while leading to fracture healing and obtaining results comparable with other more recent series. We believe that this new "Scallop Plate" is effective for the treatment of pilon fractures and should be used in conjunction with a staged procedure in the acute trauma setting.

Shaft fractures of the clavicle: current concepts.

Fractures of the clavicle are common and have been typically addressed to nonoperative treatment. Favorable results, which predominantly were achieved in the young and adolescents, were supposed to be usual in midshaft clavicular fractures. However, in the presence of comminution or complete displacement, especially when occurring in females or elderly patients, there is a marked risk of nonunion, malunion, and poor outcome. Thus, many authors prefer primary surgical stabilization, when risk factors add up. Plate fixation and intramedullary stabilization seem to be equally favored. Though, indications for operative management remain controversial. Further prospective randomized comparative clinical trials are necessary for a well-founded risk-benefit analysis.

Instructional technique guide: closed reduction of the supination-eversion Stage IV (Weber Type B) ankle fracture.

The treatment of unstable ankle fractures in patients over eighty years of age.

BACKGROUND: The current study examined the outcomes of operative treatment of unstable ankle fractures in patients at least 80 years old at the time of injury. METHODS: Of 2,682 patients who presented for treatment of ankle fractures, 17 patients met the study criteria. These patients had open reduction and internal fixation after sustaining 15 closed and two open unstable ankle fractures. There were 11 type B fractures and six type C fractures by the Danis-Weber classification, and 12 supination-external rotation and five pronation-external rotation fractures by the Laugen-Hansen classification systems. RESULTS: When noncompliant patients who developed complications were removed from analysis, the fixation failure and deep infection rates were 0% each. CONCLUSIONS: These results highlight the importance of patient compliance and non-weightbearing status in the treatment of ankle fractures in patients over 80 years.

[Screw fixation without bone graft of calcaneal joint fractures: 35 cases]. / Résultats de l'ostéosynthèse par vissage sans greffe osseuse des fractures articulaires du calcaneus: à propos de 35 cas.

PURPOSE OF THE STUDY: The prognosis of calcaneal joint fractures is less favorable than fractures without joint involvement. Surgical treatment is frequently recommended. The type of fixation and the usefulness of a bone graft remain subjects of debate. The purpose of this work was to present the functional and anatomic results obtained with simple screw fixation without bone grafting in a retrospective series of 35 displaced joint fractures of the calcaneus. MATERIAL AND METHODS: The series included 31 patients (four bilateral fractures), 86% men. Mean age was 36 years (17-60 years). Using the Duparc classification, there were 12% type III fractures and 88% type IV fractures. Horizontal joint impaction was observed in 36% of patients, vertical impaction in 8%, and mixted impaction in 56%. The mean Bohler angle was 2 degrees (range -25 degrees to 15 degrees ). According to the Utheza classification, 70% of the fractures had two sagittal fracture lines, 16.5% one sagittal fracture line, and 13.5% comminutive fractures. Incongruency of the subtalar joint was noted in 70%, with a conflict with the lateral malleolus in 50%. Mean time to surgery was 12 days (7-30 days). The sub- and retromalleolar approach was used to achieve simple screw fixation. Bone grafts were not used. Mean follow-up was two years (range 12-38 months). RESULTS: There were no serious complications. Functional outcome was analyzed with the Kitaoka scale, mean score 74.3 +/- 1.1 (range 46-98), with 16% excellent outcome, 56% good outcome, 25.2% fair outcome, and 2.5% poor outcome. There was a correlation between functional outcome and age, etiology, and type of fracture. Anatomic results were assessed with the Babin scale and were very good in 24%, good in 8%, fair in 28%, and poor in 40%. Secondary loss of the initial heightening of the joint surface was noted in 48% of the cases, 3 degrees on average. DISCUSSION: This series confirms the value of surgical treatment compared with conservative treatment. Compared with plate fixation, screw fixation exposes the patient to less risk of skin and infectious problems. Simple screwing generally provides satisfactory results with acceptable stability. In light of the present results, adjunction of a bone graft would not be necessary since the loss of correction of the joint surface height was often minimal. CONCLUSION: Screw fixation of calcaneal joint fractures is a reliable technique. Adjunction of a bone graft does not appear to be necessary.

Surgical stabilization of the cervical spine after trauma.

Surgical stabilization should be individualized for each patient. The procedure used should provide both immediate and prolonged stability at the site of instability. The choice of procedure depends on knowledge of the structures providing stability and of the mechanism of injury. Pure flexon injuries without comminution or disruption of ligaments are stable and do not require surgical treatment. Flexion-rotation dislocations, with either unilateral or bilateral facet dislocation, should be treated by posterior open reduction and fusion if they cannot be reduced by a closed method or if there is demonstratable motion on three-month flexion-extension roentgenograms. A comminuted burst ("teardrop") fracture produced by axial loading of the vertebral bodies should be stabilized by an anterior cortical strut graft for early mobilization and realignment of the spinal column to prevent progressive deformity.

Uncomplicated Mason type-II and III fractures of the radial head and neck in adults. A long-term follow-up study.

BACKGROUND: The purpose of this study was to evaluate the incidence and the long-term results of closed uncomplicated Mason type-II and III fractures in a defined population of adults. METHODS: Seventy women and thirty men who were a mean of forty-seven years old when they sustained a fracture of the radial head or neck (a Mason type-II fracture in seventy-six patients and a Mason type-III fracture in twenty-four) were reexamined after a mean of nineteen years. Radiographic signs of degenerative changes of the elbow were recorded. The fracture had been treated with an elastic bandage or a collar and cuff sling with mobilization for forty-four individuals, with cast immobilization for thirty-four, with resection of the radial head in nineteen, with open reduction of the radial head in two, and with a collateral ligament repair in one. Secondary excision of the radial head was performed because of residual pain in nine patients, and a neurolysis of the ulnar nerve was performed in one patient. RESULTS: Seventy-seven individuals had no symptoms in the injured elbow at the time of follow-up, twenty-one had occasional pain, and two had daily pain. The injured elbows had a slight flexion deficit compared with the uninjured elbows (mean and standard deviation, 138 degrees +/- 8 degrees compared with 140 degrees +/- 7 degrees ) as well as a small extension deficit (mean and standard deviation, -4 degrees +/- 8 degrees compared with -1 degrees +/- 6 degrees ) (p < 0.001 for both). The prevalence of degenerative changes was higher in the injured elbows than in the uninjured ones (76% compared with 16%, p < 0.001). CONCLUSIONS: The results following uncomplicated Mason type-II and III fractures are predominantly favorable. A secondary radial head resection is usually effective for patients with an unfavorable outcome (predominantly long-standing pain).

Pelvic ring disruptions in emergency radiology.

Pelvic ring disruptions are a result of high-energy trauma and are a significant cause of morbidity and mortality in major trauma patients. The initial pelvic radiograph, in combination with computed tomographic imaging in selected patients, provides a quick and accurate method of diagnosing pelvic fractures. Pelvic fracture classification schemes have evolved over the past few decades, and include description of the mechanism of injury and assessment of pelvic stability. Understanding these classifications is important in developing an approach to interpretation of pelvic imaging and prediction of associated injuries. Armed with these tools, the emergency radiologist can detect pelvic fractures early and guide subsequent imaging and therapy.

A mechanistic classification of closed, indirect fractures and dislocations of the lower cervical spine.

Closed, indirect fractures and dislocations of the lower cervical spine occur in families or groups within which there is a spectrum of anatomic damage to a cervical motion segment. This study of 165 cases demonstrates the various spectra of injury, called phylogenies, and develops a classification based on the mechanism of injury. The common groups are compressive flexion, vertical compression, distractive flexion, compressive extension, distractive extension, and lateral flexion. The probability of an associated neurologic lesion relates directly to the type and severity of cervical spine injury. With use of the classification, it is possible to formulate a rational treatment plan for injuries to the cervical spine.

Fractures of the tibia. Can their outcome be predicted?

We have carried out a prospective study to determine whether the basic descriptive criteria and classifications of diaphyseal fractures of the tibia determine prognosis, as is widely believed. A number of systems which are readily available were used, with outcome being determined by standard measurements including fracture union, the need for secondary surgery and the incidence of infection. Many validated functional outcomes were also used. The Tscherne classification of closed fractures proved to be slightly more predictive of outcome than the others, but our findings indicate that such systems have little predictive value.

Operative treatment of distal humeral fractures in the elderly.

We treated 49 patients at an average age of 80 years (75 to 90) with distal mostly intraarticular humeral fractures by open reduction. There were 8 class A, 13 class B and 28 class C fractures on Müller's classification. The patients were reviewed at a postoperative average of 18 months. The patients' assessment of the result was very good in 31%, good in 49%, fair in 15% and poor in 5%. The flexion-extension range was very good in 41%, good in 44% and fair in 15%. The incidence of implant failure, pseudarthrosis of the olecranon osteotomy and ulnar nerve lesion was no higher in these elderly patients than in younger patients. Old age is not a contraindication to open reduction and internal fixation; it is important to restore full function.

Fractures of the ring of the axis. A classification based on the analysis of 131 cases.

The retrospective analysis of 131 patients suffering from a fracture of the ring of the axis is reported. The injury was classified into three types according to radiological displacement and stability. Associated injuries and neurological deficit are discussed and a theory of pathogenesis presented. Guidelines for the management of each type of fracture are proposed.

The epidemiology of humeral shaft fractures.

We have analysed 249 consecutive fractures of the humeral shaft treated over a three-year period. The fractures were defined by their AO morphology, position, the age and gender of the patient and the mechanism of injury. Open fractures were classified using the Gustilo system and soft-tissue injury, and closed fractures using the Tscherne system. The fractures were classified as AO type A in 63.3%, type B in 26.2% and type C in 10.4%. Most (60%) occurred in the middle third of the diaphysis with 30% in the proximal and 10% in the distal third. The severity of the fracture and soft-tissue injury was greater with increasing injury severity. Less than 10% of the fractures were open. There was a bimodal age distribution with a peak in the third decade as a result of moderate to severe injury in men and a larger peak in the seventh decade after a simple fall in women.

Reamed or unreamed nailing for closed tibial fractures. A prospective study in Tscherne C1 fractures.

We performed a prospective, randomised study on 50 patients with Tscherne C1 tibial diaphyseal fractures comparing treatment with reamed and unreamed intramedullary nails. Our results show that reamed nailing is associated with a significantly lower time to union and a reduced requirement for a further operation. Unreamed nailing should not be used in the treatment of the common Tscherne C1 tibial fracture.

Fractures of the distal radius. A modern treatment-based classification.

The classification of fractures is necessary to make a proper assessment of the injury and to recommend appropriate treatment. This article presents a treatment-based classification that assists in directing treatment. It is straight forward and easy to remember, yet has the potential for expansion to more detailed subclassifications as desired. Specific treatment planning can result from reference to this classification.
