- PURPOSE
To compare and analyze length change of patella tendon after intramedullary nailing of tibial shaft fracture using transtendinous approach.
MATERIALS AND METHODS
Thirty-two cases were analyzed from December, 1999 to December, 2005. Insall Salvati ratios were estimated. Severity of initial trauma, duration of nail retension, knee function and pain on change of length of patellar tendon was evaluated.
RESULTS
Mean duration of nail retention was twenty-two months. The shortening of patella tendon was observed in 25 cases (p<0.001). The effect of AO type and the duration of nail retension on the decrease of Insall Salvati ratio was not significant (p>0.05, p=0.778). Lysholom score decrease to 89.5. There was no significant difference between the shortening of patellar tendon length and knee pain (p=0.058).
CONCLUSION
After intramedullary nailing for closed tibia fracture, shortening of patellar tendon length is observed. That is irrelevant to the fracture type and the duration of nail retension. The shortening of patella tendon length may contribute to decreasing of knee function, but it was no significance of knee pain after intramedullary nailing.

- PURPOSE
This study evaluated the shortening and rotational deformity after closed intramedullary nailing of femur shaft fracture according to Winquist-Hansen classification type.
MATERIALS AND METHODS
This study was based on 98 cases who received cloased intramedullary fixation about their femur shaft fractures between January 2000 and October 2005 with minimum 12 months follow up. The rotational deformity was analysed by Yang's method (45 cases) preoperatively and postoperatively, and the shortening by orthoradiogram (55 cases). Furthermore we analysed other complications, for example nonunion, infection, and metal failure.
RESULTS
We found more than 15 degrees anteversion difference of both femurs in 10 cases. Among them, 9 cases were classified to type 3, 4. According to Winquist-Hansen classification, rotational deformity ranged from 3.7° (Type 1) to 8.9° (Type 4). More than 2 cm leg length discrepancy (LLD) was found in 9 cases, all of them were classified as Winquist-Hansen classification type 3, 4. In the type 1, LLD was checked as 3.2 mm and type 4, 14.2 mm.
CONCLUSION
To prevent the shortening and rotational deformity after intramedullary fixation of Winquist-Hansen classification type 3, 4 femur shaft fracture, intraoperatively the exact contralateral femoral anteversion and length should be checked.
