OBJECTIVE: To evaluate and present our experience using the expandable nail system for the treatment of acute tibial shaft fractures. DESIGN: Retrospective study. SETTING: Two level-1 trauma centers-University teaching hospitals. METHODS: Fifty-four consecutive patients were treated by this nail system for acute tibial shaft fracture. Two nail diameters were used, 8.5 mm and 10 mm. Operation, hospitalization and healing times, reaming versus nonreaming, isolated versus multiple injuries, and reoperations were recorded and analyzed statistically. RESULTS: Follow-up was obtained either until fracture healing or for a minimum of 1 year with an average of 14 months (12 to 24). All fractures healed in an average time of 72 days (21 to 204). The average healing times for patients treated with 8.5-mm and 10-mm nails were 77.2 days (27 to 204) and 63.4 days (21 to 121), respectively. Average operative time was 103 minutes (40 to 185) if reamed and 56 minutes (30 to 80) if unreamed. Average healing times were 65.4 days (21 to 190) if reamed and 79.5 days (42 to 204) if unreamed. There were 11 complications (20.4%) related to the nailing: 3 deep infections, 2 superficial infections, 2 bone shortenings of 1 cm secondary to nail protrusion in the knee, 1 compartment syndrome, 1 fracture propagation, 1 distal malalignment, and 1 delayed union. Hardware was removed in 6 patients (3 infections, 2 patients' request and 1 protrusion into the knee), and 1 additional patient underwent exchange nailing due to a delayed union. CONCLUSIONS: The expandable nail offers the theoretical advantages of improved load sharing and rotational control without the need for interlocking screws. This study demonstrates satisfactory healing and alignment for the treatment of tibial shaft fractures using this device. However, caution must be exercised when using this nail in cases of significant comminution and in cases where the fracture pattern involves the more proximal or distal aspect of the tibial shaft. 相似文献

BACKGROUND: Studies on intramedullary nailing of humeral shaft fractures in the orthopaedic literature have shown mixed results. The purpose of this investigation was to document the clinical outcome and complications associated with the use of a new flexible, locking intramedullary nail that can be implanted in the humerus in either a retrograde or an antegrade manner without violating the rotator cuff mechanism or damaging the articular surface of the humeral head. METHODS: Fifty consecutive patients with fifty-one humeral shaft fractures were entered into our prospective clinical outcome study. The fracture was classified on the basis of the anatomic location and pattern. Implant positioning and fracture alignment were assessed postoperatively. Complications were recorded, and the time to union was measured. Shoulder function was evaluated with use of a combination of the Constant shoulder score, Short Form-36 (SF-36) clinical outcome data, range-of-motion measurements, and a subjective pain-rating scale. RESULTS: Forty-one patients with forty-two fractures had an adequate duration of clinical follow-up (a mean of twenty-two months) for analysis. Thirty-nine fractures healed, with a mean time to clinical union of twelve weeks (range, four to fifty weeks). Thirty-eight of the forty-two shoulders had minimal or no pain. Thirty-six shoulders had a full range of motion. The mean Constant shoulder score was 90 points. Four patients had five complications, which included two nonunions, two hardware failures, and one wound infection. All four patients had been managed with a 7.5-mm nail. A multivariate analysis demonstrated that an age of more than fifty years was associated with a lower Constant score and that the occurrence of a complication was associated with a lower physical component score on the SF-36. CONCLUSIONS: The flexible humeral nail allows both retrograde and antegrade implantation and static locking. Nail insertion can be accomplished without violating the rotator cuff or damaging the articular surface of the humeral head. Although the nail functioned well in most of our patients, the use of a small-diameter (7.5-mm) nail was associated with a higher complication rate. This implant should be used with caution in any patient with a medullary canal diameter of 相似文献

Intramedullary nailing of humeral shaft fractures 总被引:5,自引:1,他引:5
From 1996 until 2000 we treated 52 humeral shaft fractures with AO unreamed nailing. Mean patient age was 35.8 years and the average follow-up 29.6 months. There were 31 type A fractures, 15 type B, and 6 type C. Closed retrograde nailing was performed in 46 cases and open nailing in six. Functional results were excellent in 48 cases, moderate in three, and poor in one. 相似文献

Summary
Humeral shaft fractures can be treated either conservatively or operatively. Plating of the humerus is the established operative
method, but recently interest has also been focussed on intramedullary nailing. Fifty-nine cases of humeral fractures treated
with intramedullary nailing (Seidel/Marchetti-Vicenzi/Prévot) from January 1991 to December 1995 (44 fractures after trauma,
11 pathological fractures, 3 pseudarthroses, 1 re-fracture). Closed reduction in 55/59 cases. One infection (soft tissue);
2/48 pseudarthrosis (indication for nailing: pseudarthrosis!). No iatrogenic palsy of the radial nerve. Functional postoperative
treatment in all 44 cases of humeral fractures after adequate trauma. One poor functional result: periarticular ossification
after retrograde nailing, possibly connected with long-term respiratory treatment after trauma. Treatment of humeral shaft
fractures by intramedullary nailing is favoured in our clinic (low complication rates, excellent or good functional results,
limited approaches, small scars). Proximal fractures should be treated by the Seidel nail (stable interlocking of the proximal
fragment); very distal fractures need Prévot nailing (reaming of condylar canals). All other fractures of the humeral shaft
can be treated by each of the implants used in our clinic. Pathological fractures are an excellent indication for intramedullary
stabilization. These patients benefit from stable fixation without intense surgical trauma. Pseudarthrosis, according to our
limited experience, seems to require plating plus bone grafting. Plating is also recommended if revision of the radial nerve
becomes necessary.

The aim of this in vitro study was to compare the mechanical behavior of fixation by the Russell-Taylor nail with the more
recent Polarus nail. Fixation with an experimental nail made from polyacetal polymer was also included in the study. Thirty
humeri were fractured and randomized to receive one of the three nail types. A four-point nondestructive bending test was
performed, as well as torsional testing to failure. The torsional test was designed to record the amount of ‘play’ (uncontrolled
rotation) in the bone/implant construct. The Polarus nail gave higher rigidity of the nail/bone construct than the two other
types. The Russell-Taylor nailing exhibited a high degree of ‘play’ (uncontrolled rotation). The polyacetal nails allowed
a large elastic deformation before failure.

IntroductionThis study was designed to measure early postoperative outcomes of plate vs. nail fixation for humeral shaft fractures.Patients and methodsPatients ≥18 years who underwent plate or nail fixation for low-energy humeral shaft fractures between 2005–2016 were identified from the National Surgical Quality Improvement Program (NSQIP). Multivariable regression was used to compare postoperative outcomes using propensity score adjustment to account for differences between fixation groups. Variables included in the propensity score were age, American Society of Anesthesiologists (ASA) class, hypertension, steroid use, cancer, functional status, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), and sex.ResultsPlate fixation was used in 1418 patients (70.6%), while nail fixation was used in 591 (29.4%). Patients undergoing nail fixation were more likely to be older, have a higher American Society of Anesthesiologists (ASA) class, and have comorbidities. Mean operative time was statistically longer in the plate fixation group (130 +/−62 min vs. 102 +/−54 min). After propensity score adjustment, type of fixation was not a significant predictor of major or minor complications, length of stay, or readmission. However, nail fixation was a significant predictor of mortality following propensity score adjustment (OR 3.15, 95% Confidence interval 1.26–7.85).ConclusionPatients undergoing intramedullary nail fixation tended to be older patients with more comorbidities, suggesting that surgeons are selecting nail fixation in patients who may not be ideal surgical candidates. Although LOS, complications, and readmission rates were higher in the nail group, this difference was not statistically significant following propensity score adjustment. However, nail fixation remained an independent predictor of 30-day mortality following adjustment. This suggests that nail fixation may not be a safer surgical option in patients with multiple medical co-morbidities and low-energy humeral shaft fractures. 相似文献

Intramedullary fixation of tibial shaft fractures: a comparison of the unlocked and interlocked nail 下载免费PDF全文
The study is a prospective evaluation and comparison. Eighty-two patients with tibial shaft fractures were treated with intramedullary
fixation by either an unlocked nail (ULN) or an interlocked nail (ILN). All patients were followed up for 12 months with a
functional score evaluation. The patients were divided into two groups, based on the method of treatment. The ULN group included
42 patients with an average age of 43.1 years. The ILN group included 40 patients with an average age of 40.0 years. Both
groups were similar in the injury mechanism, fracture location, open fracture type and associated medical conditions (all
P > 0.05). The operative time was shorter and the wound size smaller in the ULN group when compared to the ILN group (P < 0.001). The union rate, healing time and malunion rate were not significantly different between the two groups (P > 0.05). Although the functional score showed no difference between the groups (P = 0.3), the ILN group had a greater ability to return to their work 6 months after surgery (P = 0.03). In conclusion, unlocked nailing for tibial shaft fractures is a simple and effective method especially in the treatment
of middle-third fractures. Interlocked nailing gives stable fixation without cast immobilisation, which resulted in a greater
ability for the patients to return to their previous work 6 months after surgery.
Résumé Etude prospective et comparative de 82 patients avec une fracture de la diaphyse tibiale traitée par clou centro-médullaire non vérrouillé (ULN) ou vérrouillé (ILN). Tous les patients étaient suivis 12 mois, avec une évaluation fonctionnelle. Le groupe ULN comprenait 40 patients d’age moyen 43.1 ans. Le groupe ILN comprenait 40 patients d’age moyen 40 ans. Les deux groupes étaient similaires pour le mécanisme, la localisation de la fracture, le type d’ouverture, et les conditions médicales générales. (tous les P > 0.05). Le temps opératoire est plus court et la taille de l’incision plus petite dans le groupe ULN (P < 0.001). Le taux de consolidation et le temps de consolidation ne sont pas différents entre les deux groupes (P > 0.05). Bien que le score fonctionnel ne montre pas de différence entre les deux groupes, le groupe ILN à une plus grande facilité à la reprise du travail 6 mois après la chirurgie (P = 0.03). En conclusion l’enclouage non vérrouillé est une bonne méthode surtout dans les fractures du tiers moyen de la diaphyse tibiale. L’enclouage vérrouillé procure une fixation stable sans immobilisation platrée donnant une plus grande capacité de reprise des activités antérieures 6 mois après la chirurgie.相似文献

Background Proximal humeral fractures occur frequently. Displaced or unstable fractures require open reduction and internal fixation.
Our objective was to investigate the clinical and radiographic results of the internal fixation using Polarus humeral nails
for fractures of the proximal humerus.
Materials and methods From January 2001 to April 2006, 54 shoulders of 54 patients (44 females, 10 males) underwent the intramedullary fixation
using Polarus humeral nail. Mean age of the patients was 66-year-old (39–89) at the time of the surgery. Fracture-type by
Neer classification was 2-part (29 shoulders), 3-part (22 shoulders) and 4-part (3 shoulders). The clinical and radiological
outcomes were evaluated.
Results All the shoulders after osteosynthesis obtained bone-union. There was no osteonecrosis of the humeral head. Functional outcome
measured by JOA score averaged 81 points. Totally 43 patients (79%) had satisfactory to excellent results. Varus deformity
was seen in 4 shoulders (8%) and the deformity of the greater tuberosity in 4 (8%).
Conclusion The Polarus intramedullary humeral nail is effective for the treatment of proximal humeral fractures. 相似文献

Background:
Lack of availability of interlocked nails made plate osteosynthesis the first choice of treatment of forearm fractures inspite of more surgical exposure, periosteal stripping and big skin incision subsequent scar along with higher risk of refracture on implant removal. We hereby report the first 12 cases with 19 forearm bone fractures internally fixed by indegenous interlocked nail.Materials and Methods:
Existing square nails were modified to have a broad proximal end of 5.5 mm with a hole for locking screw of 2.5 mm. The nail has a distal hole of 1/1.2/1.5 mm in 2.5/3/3.5 mm diameter nail, respectively. A new method of distal locking with a clip made of k wire is designed. The clip after insertion into the bone and hole in nail and opposite cortex snuggly fits the bone providing a secure locking system. Twelve skeletally mature patients, mean age 32 years (range 24-45 years) with 19 diaphyseal fractures of the forearm were treated with this indigenously made new nail. The patient were evaluated for fracture union, functional recovery and complications. The functional outcome was assessed by disabilities of arm, shoulder and hand questionnaire (DASH score).Results:
Time to radiographic union ranged between 12 and 28 weeks, with a 100% union rate. Complications were minimal, with mild infection in open fracture (n=1) and delayed union (n=1) in patient with comminuted fracture of the ulna only. The clinical results were excellent. The DASH score ranged between 0 and 36 points.Conclusion:
This new interlocking nail may be considered as an alternative to plate osteosynthesis for fractures of the forearm in adults. The advantages are benefit of closed reduction, smaller residual scar, reduced cost and early union with allowance of immediate movements. 相似文献17.

The advantages and disadvantages of interlocking Seidel's nails determined by their construction and the way of insertion were presented on the basis of own experience and literature. The advantages are strength and shape of the nails which are conductive to fragments stability and make insertion into humerus medullar canal easier. The tools set for insertion and locking of distal part. It doesn't truly protect from torsion displacements. Locking takes place by draw for a few weeks by external immobilization. The Seidel's nail has also disadvantages associated with proximal insertion. Unavoidable injury of supraspinatus tendon insertion can be the reason of loss of shoulder function. The antegrade fixation can cause pushing distal fragment downward by tip of the nail. It is necessary to control it's insertion under image intensifier. Presented disadvantages of Seidel's nail fixation didn't result in any problems in humerus fractures or pseudoarthroses healing. In one case it was necessary to perform additional decortication and space of fracture fulfillment with bone grafts. 相似文献

Antegrade interlocked humeral nailing for stabilization of humeral fractures was introduced many years ago, and studies on
this method in the orthopedic literature have shown mixed results. The purpose of this investigation was to document the clinical
outcome and complications associated with the use of an antegrade intramedullary nail (T2, Stryker) for the humeral fractures.
Between 2005 and 2008, 52 fractures of the humeral shaft were treated operatively with this intramedullary nail in our department.
Eight patients were polytraumatized, and four patients had an open fracture. The mean age of patients was 51.7 years. Forty-eight
patients had an adequate duration of clinical follow-up (a mean of 18 months) for analysis. Complications were recorded, and
the time to union was measured. Shoulder and elbow functions were assessed using the Constant Score and the Morrey Score,
respectively. Forty-six fractures healed, with a mean time to clinical union of 10.3 weeks. Two patients developed pseudarthroses.
There were four adverse events: two proximal screws backed out, one superficial infection at the insertion point, and one
fracture at the distal end of the nail. Ninety-one percentage of patients had an excellent or good shoulder function. Five
further operations were necessary: two for treatment of pseudarthroses, two for removal the backed out proximal screws, and
one wound debridement for superficial infection. Antegrade humeral nailing is a valid therapeutic option for stabilization
of humeral shaft fractures. By strictly adhering to the operation technique, the number and the severity of complications
can be reduced. When good fracture alignment and stability are obtained, uneventful bone healing with good functional results
is the rule. 相似文献

We retrospectively reviewed 48 consecutive humeral shaft fractures treated with Hackethal stacked, flexible, intramedullary (IM) nails. The indications for fixation were polytrauma or fracture patterns not amenable to bracing. The average age of patients was 40 years. Eight had associated primary nerve injuries. All fractures were reduced closed, and the nails were inserted retrograde through a distal posterior cortical window. Follow-up was possible in 33 patients. Ninety-seven percent (32 of 33) had healed at 1 year. There were no iatrogenic nerve palsies. There was one delayed union, one nonunion, one deep infection, and three occurrences of heterotopic ossification at the entry portal. Two patients with distal nail migration required second operations. Clinical examination showed normal range of motion at the shoulder and an average of 5 degrees loss of extension at the elbow. Hackethal's bundled IM nailing was shown to be a reliable, inexpensive, and relatively atraumatic method for stabilization of simple and comminuted humeral shaft fractures. 相似文献
