Intramedullary fixation of pathological fractures and lesions of the subtrochanteric region of the femur.

The Zickel intramedullary appliance was used without methylmethacrylate in forty-six patients to stabilize thirty-five fractures and eleven impending fractures associated with osseous lesions in the subtrochanteric region of the femur. Early mobilization or ambulation was possible in nearly all cases. The patients with actual fractures survived an average of 4.7 months, while those with lesions stabilized prophylactically survived an average of 13.8 months postoperatively. Fourteen of the thirty-five patients with fractures showed union after an average of 4.5 months.

Compartment pressure monitoring during intramedullary fixation of tibial fractures.

Twenty-six legs in 25 patients were monitored prospectively for compartment pressures during intramedullary nailing of open and closed tibial shaft fractures. Twenty-three patients were treated within 24 hours of admission. Twenty-three unreamed and three reamed intramedullary rods were utilized. Compartment pressures were measured initially, following fracture reduction, and during reaming. Pressures were also measured at the completion of nailing with the ankle dorsiflexed and at rest (plantar flexed) to determine positional effects on compartment pressures. Nine fractures (35%) were found to have persistently elevated pressures (> 40 mm Hg) and underwent immediate four-compartment fasciotomy. The remaining group of 17 fractures (65%) was monitored throughout the intraoperative period. No patient monitored intraoperatively developed postoperative compartment syndrome.

Intramedullary fixation of tibial shaft fractures: a comparison of the unlocked and interlocked nail.

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.

Unstable trochanteric femoral fractures: extramedullary or intramedullary fixation. Review of literature.

For operative treatment of unstable trochanteric fractures two options exist: extramedullary or intramedullary stabilisation. A review of 18 international papers that compared two different treatment methods for trochanteric fractures, in prospective randomised clinical trials, is presented. In view of the overall results, routine use of intramedullary fixation devices is not to be recommended for stable trochanteric fractures. For these fractures one of the sliding hip screw systems provides a safe and simple alternative. For unstable fractures intramedullary implants are (biomechanically) superior. The review shows that clinical advantages of both treatment methods are suggested and advocated, but still remain to be demonstrated on evidence base.

The role of intramedullary fixation in open fractures.

Intramedullary nailing of open fractures requires careful surgical judgment, consideration of alternative techniques, and the ability to use a number of different methods, including various designs with or without obligatory reaming. With good technique and well-selected indications, intramedullary nailing of open fractures may offer advantages not available through other types of fracture stabilization. Open fractures of the femur are best treated with delayed closed reamed nailing. Acute open nailing of the femur is justified to salvage life and limb in multiply injured patients. Acute nonreamed nailing of open fractures of the tibia has been shown to give results comparable to external skeletal fixation. The role for intramedullary nailing of open fractures of the upper extremity is limited.

The treatment of open tibial fractures using nonreamed flexible intramedullary fixation.

Many fixation methods for the treatment of open tibial fractures have been devised, studied, and compared, but controversy persists regarding the most suitable means of immobilization. Nonreamed flexible intramedullary fixation nails, such as Ender rods, have proved an excellent alternative for stabilizing a variety of open tibial fractures with varying degrees of soft-tissue damage. These nails act as an internal splint, which provides three-point fixation; preserves much of the primary blood supply of the tibia; allows for maintenance of length, alignment, and rotation; and facilitates healing of adjacent injured soft tissues. Their use deserves consideration in treating most open diaphyseal tibial fractures.

Intramedullary fixation for pediatric unstable forearm fractures.

Forty-nine children with diaphyseal both-bone forearm fractures were treated with either both-bone intramedullary wire fixation (24), single ulnar intramedullary wire fixation (22), or single radial intramedullary wire fixation (3). Six fractures were open and 43 were closed. A limited open approach to one or both bones was necessary for insertion of the intramedullary wire in 10 of 43 closed fractures. All both-bone and single radial intramedullary wire fixations healed with less than 5 degrees angulation. Progressive reangulation of the nonfixed radial fracture after an initial satisfactory reduction was seen in seven of the 22 fractures treated with single ulnar intramedullary wire fixation. In four patients, the reangulation was controlled by a change of cast and molding of the fracture and was between 8 degrees and 12 degrees at union. In two other patients a second operative procedure was required to reduce and internally fix the radius. One fracture healed with a radial angulation of 25 degrees. Three fractures in older patients showed late reangulation after early removal of intramedullary wires at 5 weeks. The results of the current study suggest that the radius and ulna should be stabilized with intramedullary wires and that the wires should be buried to reduce the need for early removal.

Intramedullary screw fixation of Jones fractures.

BACKGROUND: Jones fractures of the fifth metatarsal can be stabilized using intramedullary screw fixation techniques. A range of screw diameters from 4.5 mm to 6.5 mm can be used, but the optimal screw for this procedure has yet to be defined. In clinical practice, we have observed that failure is more likely when smaller diameter screws are used. METHODS: Experimental Jones fractures were created in 23 pairs of human cadaver fifth metatarsals, which were fixed using either 5.0 mm or 6.5 mm screws. Fracture stiffness and pull-out strengths were measured for either screw type and their relationships with bone mineral density and medullary canal diameter were determined. RESULTS: There was no significant difference in the bending stiffness of fractures stabilized with 5.0 mm and 6.5 mm screws; however, different mechanisms of failure were noted for either screw type. Poor thread purchase within the medullary canal was noted with the 5.0 mm screws, while excellent purchase was noted with 6.5 mm screws. Pull-out strength testing revealed significantly higher pullout strengths for the larger 6.5 mm screws. There was no significant difference in bone mineral density or medullary canal diameter between right and left metatarsals. CONCLUSIONS: Fifth metatarsals can often accommodate a 6.5 mm screw for the stabilization of Jones fractures. Larger diameter screws did not result in greater fracture stiffness in our model, but did result in significantly greater pull-out strengths. CLINICAL RELEVANCE: Larger diameter screws may be more appropriate for intramedullary screw fixation of Jones fractures.

Intramedullary fixation of unstable forearm fractures in children.

Although most forearm fractures in children are appropriately treated with closed reduction and cast immobilization, certain unstable fractures of the radius and ulna are best treated operatively. We present our technique of using flexible intramedullary fixation to stabilize these fractures. Retrograde fixation of the radius is obtained with a 5/64th or 3/32nd Steinmann pin, and stabilization of the ulna is achieved with a 1/8th inch Rush rod. Complications from this technique are few. The rods are usually removed after fracture union to avoid painful hardware.

[Moderate results of the treatment of femoral shaft fractures in children using intramedullary fixation].

OBJECTIVE: To evaluate the results of treatment of femoral shaft fractures in children with intramedullary nailing. DESIGN: Retrospective. SETTING: Department of Surgery, University Hospital Utrecht, Department of Paediatric Surgery, Wilhelmina Children's Hospital, Utrecht. METHOD: Between 1982 and 1993, 27 femoral shaft fractures in 27 patients under the age of 16 were treated by intramedullary nailing. The charts and radiographs of these patients were reviewed and 24 patients were seen for follow-up examination (mean 7.5 years). Leg length was measured radiographically and anteversion of the affected and normal femora was determined by a standard computed tomography (CT) study. RESULTS: The average hospital stay was 34 days. There were no postoperative complications. At follow-up 10 patients had a leg length discrepancy < 1 cm and a rotational deformity < 10 degrees. Three patients had a shortening of the injured leg > 1 cm (max. 1.7 cm), in 6 patients the injured leg was more than 1 cm longer (max. 3.5 cm). The difference in rotation between fracture side and unaffected side was > 10 degrees in 9 patients. In 6 patients this was due to increased exorotation (max. 22 degrees) and in 3 patients to increased endorotation (max. 27 degrees). Iatrogenic injury of the epiphyseal line was not seen. CONCLUSION: Regarding leg length differences and rotational deformities intramedullary nailing was not superior to the known results of conservative treatment. The indication for operation should be carefully considered and during an operation there should be perfect control of reduction.

Intramedullary fixation of pertrochanteric hip fractures with the short AO-ASIF proximal femoral nail.

INTRODUCTION: The advantages of intramedullary fixation of pertrochanteric hip fractures over dynamic screw-plate devices in the clinical setting are still a matter of debate. We performed a case series study in a teaching hospital to analyse the results of the recent AO-ASIF proximal femoral nail (PFN). MATERIALS AND METHODS: Between July 1998 and May 2001, 46 consecutive patients (47 fractures) were included in the investigation. The average patient age was 76.4 years (range 50-93 years), and most fractures (74.5%) were unstable. Operative details, adequacy of fracture reduction, screw position in the femoral head, re-operations, and postoperative complications were documented. Functional results were evaluated by the Parker and Palmer mobility score and Barthel Index for patients with a minimum follow-up of 4 months. RESULTS: Intraoperative technical or mechanical complications occurred in 11 patients (23.4%), mostly problems with the distal nail locking and fracture of the lateral wall of the greater trochanter. Mean surgical time was 83.4 min. The lateral protrusion of screws causing thigh pain was the most common postoperative complication, with an incidence of 21.2%. There was only one femoral shaft fracture at the nail tip caused by a fall at 9 months of follow-up. Five patients (10.6%) had intra-articular migration of screws, which was associated with loss of reduction and varus collapse in one case. There were 2 persistent deep infections and 2 haematomas that required surgical drainage. The re-operation rate was 19.1%, mainly cephalic screw removal due to lateral protrusion at the proximal thigh. Ten patients (32.2%) fully recovered their Parker and Palmer mobility score, and 20 patients (66.6%) recovered more than 90% of their pre-injury Barthel Index values. The average limb shortening was 14 mm. Mortality rate during the observation period was 20.4%. CONCLUSION: In view of only one loss of reduction with varus collapse clearly caused by a technical error, we concluded that the PFN is a suitable implant for unstable fractures, but the high re-operation rate precludes its routine use for every pertrochanteric fracture.

[Intramedullary fixation of pediatric bone shaft fractures].

Intramedullary stabilisation (Prévot-nailing) of shaft fractures in childhood allows full weight bearing without cast. Early fracture healing is seen by respecting soft tissue around fracture and by using distal or proximal approaches. Good indications of femoral shaft osteosynthesis are recommended in oblique- and transverse-fractures. Intramedullary stabilization seems to be a good alternative methode instead of casting calf-shaft-fractures. An instable fracture of forearm may be treated intramedullary to avoid often observed displacement ad axim and rotation. Humoral fractures primary have to be treated conservatively. Only in displaced fractures or in cases with additional injuries an intramedullary procedure with free range of motion is recommended.

The use of elastic nails for intramedullary fixation of humeral fractures and nonunions.

From May 1993 to January 1997, a total of 130 humeral fractures and nonunions were treated using an "elastic" unreamed nail. The elastic nail consists of a cylindrical proximal component tapered for the application of the impactor-extractor, distally containing the proximal ends of four or five secondary nails preloaded to diverge and held together by a retaining system. The surgical approach is through the olecranic fossa apex. Once introduced, the proximal end of the nail locks automatically by diverging the secondary nails in the proximal humeral epiphysis. Distally, the elastic nail is locked with a crossbolt. The elastic nail enables stable fixation of fractures or nonunions and allows early rehabilitation.

Intramedullary fixation of metatarsal fracture and nonunion. Two methods of treatment.

Fracture of a metatarsal is one of the most common fractures in the foot. The location of the fracture depends to some extent on the metatarsal involved, the activity, and the foot shape. The goal of treatment is to achieve a successful outcome and to avoid prolonged disability. This article covers patient selection, surgical technique, and postoperative care.

Intramedullary fixation of humeral shaft fractures.

In this paper we document seventy fractures of the humeral shaft that were treated by intramedullary fixation between 1970 and 1981. Complications developed in forty-seven (67 per cent) of the fractures, and forty-five (64 per cent) required at least one additional operative procedure. Of the sixty fractures that were internally fixed within six weeks after injury, nine (15 per cent) had a delayed union and five (8.3 per cent) had a non-union, two of which persisted despite subsequent surgery. Three of the ten fractures that were internally fixed more than six weeks after injury never united despite additional procedures that were done to secure union. Delayed union and non-union were more common in open fractures (33 per cent) than in closed fractures (21 per cent), and with open reduction (39 per cent) than with closed or so-called semi-open reduction (9 per cent). Deep infection occurred in three (5 per cent) of the fractures and was more common in open (17 per cent) than in closed fractures (2 per cent). One of the three open fractures that were treated by immediate fixation became infected, as compared with only one of the nine open fractures treated by delayed fixation. Painful adhesive capsulitis of the shoulder developed in thirty-four (56 per cent) of the patients who had fractures treated with distally directed pins, but motion of the elbow was not restricted in the nine patients with fractures treated with proximally directed pins.
