Comminuted long bone fractures in children. Could combined fixation improve the results?

Comminuted diaphyseal fractures in the pediatric age group represent a major orthopedic problem. It is associated with a high incidence of complications and poor outcomes because of the instability and difficulty in treatment. The aim of this study was to evaluate the efficacy of combined external skeletal fixation and flexible intramedullary nails in reconstruction of comminuted diaphyseal fracture in skeletally immature patients. Combined external fixator and elastic stable intramedullary nails were used in the management of 27 pediatric patients (15 males and 12 females) with unstable comminuted diaphyseal fractures of the tibia and femur. There were 19 fractures of the femur and eight fractures of the tibia. The average age of the patients was 8.7 years (range 7-14 years) for the femur and 10.8 years (range 6-15 years) for the tibia. Fractures were classified according to the system of Winquist and Hansen as grade II (five cases), grade III (nine cases), and grade IV (13 cases). All cases were operated within 6 days (range 0-6 days) after injury. The mean follow-up period was 2.8 years (range 2-3.5 years). The average duration of the external fixation was 1.6 months for fractures of the tibia, whereas it was 1.4 months for fractures of the femur. The average time for tibia fracture union was 2.8 months for fractures of the tibia, whereas it was 1.9 months for fractures of the femur. Malalignment in varus less than 5° was noted in one patient. One patient had a limb-length discrepancy of 1.5 cms. There were five cases (18.5%) with pin-tract infection. According to the Association for the Study and Application of the Methods of Ilizarov evaluation system, bone results were excellent in 23 cases (85.2%), good in three cases (11.1%), and poor in one case (3.7%). Functional results were excellent in 22 (81.5%) cases and good in five (18.5%) cases. Combined use of external fixators and elastic intramedullary nails is a good method for the treatment of comminuted long bone fractures in children.

Paratrooper's ankle fracture: posterior malleolar fracture.

BACKGROUND: We assessed the frequency and types of ankle fractures that frequently occur during parachute landings of special operation unit personnel and analyzed the causes. METHODS: Fifty-six members of the special force brigade of the military who had sustained ankle fractures during parachute landings between January 2005 and April 2010 were retrospectively analyzed. The injury sites and fracture sites were identified and the fracture types were categorized by the Lauge-Hansen and Weber classifications. Follow-up surveys were performed with respect to the American Orthopedic Foot and Ankle Society ankle-hindfoot score, patient satisfaction, and return to preinjury activity. RESULTS: The patients were all males with a mean age of 23.6 years. There were 28 right and 28 left ankle fractures. Twenty-two patients had simple fractures and 34 patients had comminuted fractures. The average number of injury and fractures sites per person was 2.07 (116 injuries including a syndesmosis injury and a deltoid injury) and 1.75 (98 fracture sites), respectively. Twenty-three cases (41.07%) were accompanied by posterior malleolar fractures. Fifty-five patients underwent surgery; of these, 30 had plate internal fixations. Weber type A, B, and C fractures were found in 4, 38, and 14 cases, respectively. Based on the Lauge-Hansen classification, supination-external rotation injuries were found in 20 cases, supination-adduction injuries in 22 cases, pronation-external rotation injuries in 11 cases, tibiofibular fractures in 2 cases, and simple medial malleolar fractures in 2 cases. The mean follow-up period was 23.8 months, and the average follow-up American Orthopedic Foot and Ankle Society ankle-hindfoot score was 85.42. Forty-five patients (80.36%) reported excellent or good satisfaction with the outcome. CONCLUSIONS: Posterior malleolar fractures occurred in 41.07% of ankle fractures sustained in parachute landings. Because most of the ankle fractures in parachute injuries were compound fractures, most cases had to undergo surgical repairs.

The role of dynamisation vis-à-vis non-dynamisation after closed interlocking nailing in cases of closed tibial shaft fractures in adults.

The importance of dynamisation after static locked nailing in comminuted closed tibial fractures is a matter of contention. A prospective study was undertaken among 178 patients in the department of orthopaedics at RG Kar Medical College, Kolkata from January 2002 to December 2006, to analyse the usefulness of this procedure with respect to the degree of comminution. In this study it was seen that dynamisation was found to be of statistical significance in relatively less comminuted fractures as per Winquist-Hansen's classification.

Leg length discrepancies in adult femoral shaft fractures treated with intramedullary nailing.

BACKGROUND: To evaluate the leg length discrepancy (LLD) retrospectively in adult femoral shaft fractures treated with intramedullary nailing (IMN). METHODS: Sixty-three patients (58 male, 5 female; mean age 29.9+/-12.4; range 15 to 77 years) were included in the study. Fractures were identified according to the Winquist-Hansen (W) system and AO classification. 16 W0, 18 WI, 16 WII, 7 WIII, and 6 WIV fractures and 35 type A, 22 type B, and 6 type C fractures were repaired. Thirty-one (49.2%) patients had multiple injuries. Fourteen patients sustained an open fracture. LLDs were measured on physical examination and using orthoroentgenography. RESULTS: The mean follow-up was 90.2+/-29.9 (39-193) months. The mean LLD was 12.3+/-15.2 [12-(-60)] mm using orthoroentgenography and 12.9+/-13.7 [10-(-60)] mm according to manual measurement. In seven cases, no LLD was observed. Twenty-seven shortenings and one lengthening were observed in the 28 femurs with a discrepancy greater than 10 mm (44.4%). There was no statistical correlation between LLD and open or closed fracture (r=0.02, p=0.86), polytrauma (r=-0.09, p=0.47), or delayed surgery (p=0.31), but there was a tendency to a greater discrepancy in comminuted fractures (WIII, IV) (r=0.33, p=0.007). CONCLUSION: LLD may be seen in high rates in adult femoral shaft fracture cases treated with IMN. Static IMN following absolute restoration of the length may prevent this problem in femoral diaphysis fractures, especially comminuted WIII and IV types.

Locked intramedullary nailing for the treatment of femoral shaft fractures: experience and result in 19 cases.

BACKGROUND: Fractures in the proximal or distal third of the femoral shaft or those with severe comminution are known to be less suitable for intramedullary nailing with Kuntscher nail. With the introduction of interlocking intramedullary nailing the problems of rotational malalignment and shortening that accompany such fractures are now less common. At the National Orthopaedic Hospital Igbobi, Interlocking Intramedullary Nailing was introduced as a form of surgical treatment for fractures of the femur, our initial experience in this type of intramedullary nailing form the basis of this report. METHOD: This is a retrospective study of all cases of fractured femur that were treated with locked intramedullary nailing between March 2002 and September 2003. RESULTS: During a 19-month period, 19 patients with 19 fractures were treated for fracture of the femoral shaft with locked intramedullary nailing using the Russell-Taylor (18 fractures) and Grosse-Kempf (1 fracture) nails. Thirteen fractures (68.5%) had comminution of the Winquist-Hansen type III and IV 12 of which were statically locked. There were three intra-operative technical problems including the case of a subtrochanteric fracture, where the nail missed the medullary canal of the proximal segment. There were 2 cases of superficial wound infection, which responded to local wound care and antibiotics. Although limb length discrepancy and rotational mal-alignment were not assessed routinely during the follow-up of patients, no symptomatic malrotation was recorded. Sixteen out of the 19 patients were available for follow-up for an average period of 11 months. All these cases progressed to union, without the need for dynamization in statically locked fixations. CONCLUSION: In spite of the initial problems encountered with this relatively new procedure in our centre, we were able to achieve a reasonably good result in addition to supporting the notion that dynamization of a statically locked nail is not always necessary for healing of fractures.

Tibiotarsal fracture repair in a bald eagle (Haliaeetus leucocephalus) using an interlocking nail.

A 14-yr-old, 5.13-kg bald eagle (Haliaeetus leucocephalus) was hit by a car and presented to the Michigan State University Small Animal Clinic with an open, grade II, transverse, midshaft, Winquist-Hansen type-II-comminuted left tibiotarsal fracture. The fracture was reduced and fixation established with a 4.7-mm-diameter, 112-mm-long, four-hole veterinary intramedullary interlocking nail maintained in position by single 2-mm transcortical screws placed in the main proximal and distal fragments. The bird was weight bearing on the bandaged limb 48 hr postoperatively. Radiographs obtained 4 wk postoperatively revealed bridging callus over three of four cortices. The bird was released after 5 mo of rehabilitation.
