  • TREATMENT OF Pipkin TYPE I FRACTURE OF FEMORAL HEAD ASSOCIATED WITH POSTERIOR DISLOCATION OF THE HIP

    Objective To evaluate and compare the outcomes of simple closed reduction, selective fragment excision after closed reduction, and emergency fragment excision and reduction in the treatment of Pipkin type I fracture of femoral head associated with posterior dislocation of the hip. Methods Between January 2002 and January 2008, 24 patients with Pipkin type I fracture of the femoral head associated with posterior dislocation of the hip were treated with simple closed reduction (closed reduction group, n=8), with selective fragment excision after closed reduction (selective operation group, n=8), and with emergency fragment excision and reduction (emergency operation group, n=8). In the closed reduction group, there were 6 males and 2 females with an average age of 37.6 years (range, 19-56 years); injuries were caused by traffic accident in 6 cases, by fall ing from height in 1 case, and by crushing in 1 case with a mean disease duration of 3.1 hours (range, 1.0-7.5 hours); and the interval from injury to reduction was (4.00 ± 2.14) hours. In the selective operation group, there were 7 males and 1 female with an average age of 37.3 years (range, 21-59 years); injuries were caused by traffic accident in 7 cases and by fall ing from height in 1 case with a mean disease duration of 3.2 hours (range, 1.0-6.0 hours); and the interval from injury to reduction was (3.90 ± 1.47) hours. In the emergency operation group, there were 5 males and 3 females with an average age of 35.5 years (range, 20-58 years); injuries were caused by traffic accident in 5 cases, by fall ing from height in 1 case, and by crushing in 2 cases with a mean disease duration of 3.3 hours (range, 1.5-6.5 hours); and the interval from injury to open reduction was (5.10 ± 2.04) hours. There was no significant difference in the age, gender, disease duration, and interval from injury to reduction among 3 groups (P gt; 0.05). Results All wounds in selective operation group and emergency operation group healed primarily. All the patients were followed up 24 to 58 months (mean, 38.7 months). According to Thompson-Epstein system, the excellent and good rates were 50.0% (4/8) in the closed reduction group, 87.5% (7/8) in the selective operation group, and 87.5% (7/8) in the emergency operation group at 24 months after operation, showing significant difference among 3 groups (χ2=9.803, P=0.020). Heterotopic ossification was found in 1 case (12.5%) of the closed reduction group, in 4 cases (50.0%) of the selective operation group, and in 4 cases (50.0%) of the emergency operation group, and avascular necrosis of femoral head was found in 2 cases (25.0%) of the closed reduction group; there was no significant difference in compl ications among 3 groups (P gt; 0.05). Conclusion The treatment of Smith-Petersen approach and fragment excision by selective operation or emergency operation has similar outcome, which are better than the treatment of simple closed reduction.
