Treatment of type IIIa open fractures with Ilizarov fixation and delayed primary closure in high-velocity gunshot wounds.

A total of 142 patients with 163 Gustilo-Anderson type IIIa limb fractures resulting from high-velocity gunshot wounds were treated with primary delayed closure and Ilizarov fixation in our department between 1988 and 1998. Average follow-up was 72.4 months. The average union period in fractures without bone loss was 16.8 weeks. It took 2 months for each 1 cm of bone defect to heal in fractures with bone loss. All fractures healed with good anatomic alignment and functional outcomes. Complications included pin-track infection in 72 fractures (50.7%), post-traumatic osteomyelitis in 5 tibial fractures without bone loss (3.1%), delayed union in 25 fractures (15.3%), nonunion in 10 (4 with bone loss) fractures (6.1%), and refracture in 4 fractures (2.4%). Our results indicate that type IIIa limb fractures caused by high-velocity gunshot wounds can be treated with Ilizarov fixation and primary delayed closure with a low overall complication rate and a remarkably low infection rate.     

Improvement in technique for arthroscopic ankle fusion: results in 15 patients

We retrospectively assessed time until consolidation, complications, and functional results according to Morgan from the clinical charts and radiographs of 15 arthroscopic ankle fusions. In 11 patients unilateral distraction and crossed screw placement over the fusion area through tibia and fibula were used (group A); in 4 patients a technique of bilateral distraction and parallel screw placement from the dorsal side of the tibia into the neck of the talus was used (group B). In group A there were two cases of insufficient compression at the arthrodesis site, three cases of suboptimal compression, and five cases of malposition of the screws. In all cases in group B good compression and fixation was achieved, and no case of malpositioning of screws occurred. There was nonunion in 3 of 11 patients in group A and in none of the four patients in group B. Time until fusion was 23.3 in group A and 12.5 weeks in group B. Functional results were better in group B. The initial experiences with our technique of bilateral distraction and parallel screw placement are therefore promising. Screw placement is easier and optimal compression and fixation are achieved. We feel that this technique should be considered when performing an arthroscopic ankle fusion.

The role of periosteal flap in the prevention of femoral widening in anterior cruciate ligament reconstruction using hamstring tendons

Tunnel widening in anterior cruciate ligament reconstruction has been reported for many years, whatever the type of plasty (allo- or autograft) or graft (patellar or hamstring tendons). Recently, the hypothesis has been formulated that widening would be responsible for later laxity of the knees. Micromobility of the graft or biological factors are classically responsible for the enlargement. In order to improve the biological conditions around the graft within the tunnel, we have developed a surgical technique using a periosteal flap. The periosteal flap is harvested at the superior and medial metaphysis of the tibia and wrapped around the proximal part of the four strands of gracilis and semitendinosus tendons near the outlet of the femoral tunnel. Forty-one patients with isolated rupture of the ACL were included in a prospective and randomized study: the first group of 20 patients had femoral fixation by Transfix and resorbable screw, the second group of 21 patients had femoral fixation by Transfix and periosteal flap. The diameters of the tunnel were measured between the sclerotic margins at the tunnel entrance and 1 cm above, and compared to the peroperative drill size. The percentage change in diameter was calculated as: (tunnel diameter–drill size)/drill size. The two groups of patients were comparable as to gender, side, age, KT-1000 side to side difference, femoral tunnel diameter and follow-up. At 2.5 months and 11 months postoperatively on average, there was a significant reduction of enlargement at the outlet of the tunnel with the use of a periosteal flap but widening was constant.     

Classification,investigation, and management of midfoot sprains: Lisfranc injuries in the athlete

BACKGROUND: Midfoot sprains in athletes represent a spectrum of injuries to the Lisfranc ligament complex, from partial sprains with no displacement to complete tears with frank diastasis. Treatment of these injuries varies from the treatment of high-velocity injuries seen in nonathletes. PURPOSE: We wanted to report the outcome of treatment in athletes with Lisfranc injuries classified according to our system. STUDY DESIGN: Retrospective cohort study. METHODS: Weightbearing radiographs and bone scintigrams were used to diagnose midfoot sprains in 15 athletes who were treated surgically or nonoperatively according to the following classification: nonoperative management for stage I injuries (undisplaced) and anatomic reduction with fixation for stage II (diastasis with no arch height loss) and stage III (diastasis with arch height loss) injuries. RESULTS: We achieved an excellent outcome in 93% of 15 athletes with midfoot sprains at an average follow-up of 27 months (range, 9 to 72). CONCLUSIONS: Weightbearing radiographs and bone scintigrams are sensitive, reproducible, and relatively inexpensive methods of investigation of these injuries. Restoration and maintenance of the anatomic alignment of the Lisfranc joint is the key to appropriate treatment of injury to the midfoot.

External fixation combined with limited internal fixation in the treatment of pilon tibia fractures

BACKGROUND/AIM: Intraarticular fractures of the tibial plafond (pilon fractures) belong to the group of most severe fractures. They are usually caused by high-energy trauma and frequently associated with a marked soft-tissue damage. Surgical treatment has replaced the traditional nonoperative treatment. The aim of this study was to present the results of the treatment of distal tibial intraarticular fracture by the use of internal fixation, as well as the combination of minimal internal fixation and external fixation. METHODS: The study included 47 patients with pilon tibia fractures who went through at the Clinic for Orthopedics and Traumatology, School of Medicine, Nis (1995-2004). Within the analayzed group there were 33 (70.2%) males and 14 (29.8%) females. The patients mean age was 45.8 years. In the first group, which consisted of 22 patients, open reduction and internal fixation of both the tibia and the fibula was performed in the two separate incisions. The second group consisted of 25 patients managed with external fixation by external fixator "Mitkovi?" with limited internal fixation. Besides external fixation, a minimal internal fixation was performed by the use of Kirschner wires and screws. The patients were followed-up inside a 24-months-period. Results. The obtained was a substantially high number of complications after open reduction and internal fixation in the group of patients. There was no difference in a long-term clinical outcome. Postoperative osteitis, as the most severe complication in the management of closed pilon tibia fractures, was not registered in the second group. CONCLUSION: Considering the results obtained in this study, it can be concluded that external fixation by the "Mitkovi?" external fixator with the minimal internal fixation is a satisfactory method for the tratment of fractures of the tibial plafond causing less complications than internal fixation.     

The hip fluid seal—Part II: The effect of an acetabular labral tear,repair, resection,and reconstruction on hip stability to distraction

Purpose

The acetabular labrum is theorized to be important to normal hip function by providing stability to distraction forces through the suction effect of the hip fluid seal. The purpose of this study was to determine the relative contributions of the hip capsule and labrum to the distractive stability of the hip, and to characterize hip stability to distraction forces in six labral conditions: intact labrum, labral tear, labral repair (looped vs. through sutures), partial resection, labral reconstruction with iliotibial band, and complete resection.

Methods

Eight cadaveric hips with a mean age of 47.8 years (SD 4.3, range 41–51 years) were included. For each condition, the hip seal was broken by distracting the hip at a rate of 0.33 mm/s while the required force, energy, and negative intra-articular pressure were measured. For comparisons between labral conditions, measurements were normalized to the intact labral state (percent of intact).

Results

The relative contribution of the labrum to distractive stability was greatest at 1 and 2 mm of displacement, where it was significantly greater than the role of the capsule and accounted for 77 % (SD 27 %, p = 0.006) and 70 % (SD 7 %, p = 0.009) of total distractive stability, respectively. The relative contribution of the capsule to distractive stability increased with progressive displacement, providing 41 % (SD 49 %) and 52 % (SD 53 %) of distractive stability at 3 and 5 mm of distraction, respectively. The maximal distraction force required to break the hip seal in the intact labral state (capsule removed) varied from 124 to 150 N. Labral tear, partial resection, and complete resection resulted in average maximal distraction forces of 76 % (SD 34 %), 29 % (SD 26 %), and 27 % (SD 22 %), respectively, compared to the intact state. Through type labral repairs resulted in significantly greater improvements (from the labral tear state) in maximal negative pressure generated, compared to looped type repairs (median increase; +32 vs. ?9 %, p = 0.029). Labral reconstruction resulted in a mean maximal distraction force of 66 % (SD 35 %), with a significant improvement of 37 % compared to partial labral resection (p < 0.001).

Conclusion

The acetabular labrum was the primary hip stabilizer to distraction forces at small displacements (1–2 mm). Partial labral resection significantly decreased the distractive strength of the hip fluid seal. Labral reconstruction significantly improved distractive stability, compared to partial labral resection. The results of this study may provide insight into the relative importance of the capsule and labrum to distractive stability of the hip and may help to explain hip microinstability in the setting of labral disease.
