PURPOSE
To analyze the patterns of and risk factors for fixation failure after hip nailing in intertrochanteric (IT) hip fractures.
MATERIALS AND METHODS
Fourteen patients who sustained a fixation failure after hip nailing for IT hip fractures were enrolled in this study. The mean age at the index surgery was 74.5 years and the mean time to the fixation failure was 6.6 weeks. All of the serial radiographs up to the fixation failure and pre-operative 3-D computed tomography were analyzed.
RESULTS
According to AO classification, there were 7 stable fractures and 7 unstable ones. Of the total of 14 cases, 10 showed a comminution of the greater trochanter tip and incomplete anatomical reduction of the medial and anterior cortex at the fracture site. Of the 10 cases with appropriate position of the lag screw within the femoral head, 9 showed a high pertrochanteric fracture (HPF) pattern. The mechanism of the fixation failure was rotation of the femoral head in 7 of 9 cases with HPF and varus collapse of the proximal fragment in 4 of the other 5 cases.
CONCLUSION
The HPF pattern, the comminution of the greater trochanter tip, and incomplete reduction of the medial and anterior cortex may be additional risk factors of fixation failure after treating IT hip fractures with hip nailing in.

Minimal Open Reduction and Interlocking IM Nailing of Comminuted Humeral Shaft Fracture: Comparison between Plate Internal Fixation: Kyeong Jin Han, Soo Ik Awe, Tae Young Kim, Shin Young Khang; J Korean Soc Fract 2002;15(4):573-580. Published online October 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.4.573

Abstract PDF: PURPOSE
We compared the functional and radiological results after the minimal open reduction and interlocking IM nailing and LC-DCP plate internal fixation for the comminuted humeral shaft fractures.
MATERIALS AND METHODS
Fourteen plates(LC-DCP) and eighteen interlocking IM nail(AO unreamed IM nail) were applied after open reduction for 32 comminuted fractures of the humeral shaft between March 1997 and December 2001. They were followed up for a minimum 9 months after surgery and the radiological and functional results were evaluated.
RESULTS
The average fracture healing time was 13.2 weeks and union rate was 85.7% for plate internal fixation. The average fracture healing time was 12.4 weeks and union rate was 94,4% for interlocking IM nail. The average functional scores according to American Shoulder and Elbow Surgeon 's (ASES) shoulder score(Total 52 points) was 44 points for plate internal fixation and 47 points for interlocking IM nailing respectively.
CONCLUSION
Minimal open reduction and interlocking IM nailing is better method with good functional and radiological results than plate internal fixation for the comminuted humeral shaft fractures.

Malailgnment Following Intramedullary Nailing of Tibial Shaft Fracture - s comparison between medial parapatellar approachand patellar tendon spltting approach -: Dong Ju Chae, Phil Hyun Chung, Tae Young Kim; J Korean Soc Fract 1998;11(4):849-857. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.849

Abstract PDF: Intramedullary nailing is often the treatment of choice in the management of fractures in the tibial diaphysis. One of the most frequent complications of tibial nailing is fracture malalignment leading to angulatory or rotational deformities. Access to the proximal tibia for intramedullary nailing of the tibial shaft fractures may be via a patallar tendon splitting or paratendinous exposure. Although the tendon splitting approach is more direct, the incidence of knee pain is significantly higher when this technique is used. In addition, several cases of heterotopic ossification have been reported following tendon splitting approaches. For these reasons an incision medial to the tendon is generally chosen. We reviewed 140 cases(131 patients) of tibial shaft fractures who were treated by use of the intramedullary nailing from 1994 to 1997 and made a comparison between the medial parapatellar approach and the patellar tendon splitting approach about degree of malalignment. We have noticed that there was significant difference in the number of tibias that were malaligned after tibial nailing with the medial parapatellar access and the tendon splitting approach. With the medial parapatellar approach, malalignment was seen in 13/42 tibiae(31.0%) of the fractures of tibial shaft, 11/12 tibiae of the proximal third fractures and 2/10 tibiae of the distal third fractures respectively. With the patellar tendon splitting approach, malalignment was seen in 8/98 tibiae(8.2%) of the fractures of the tibial shaft, 4/15 tibiae of the proximal third fractures, 1/45 of the middle third fractures and 3/38 tibiae of the distal third fractures respectively. We conclude that the tendon splitting approach may be better for intramedullary nailing of the proximal fractures of the tibia and the medial parapatellar approach may be chosen for the treatment of the middle and distal shaft fractures of the tibia.

Treatments of Tibial Condylar Fractures: Yong Bum Park, Chung Soo Hwang, Phil Hyun Chung, Suk Kang, Dong Ju Chae, Han Chul Kim, Sang ho Moon, Seung Hun Lee, Tae Young Kim, Sun Hyun Yun; J Korean Soc Fract 1998;11(4):790-797. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.790

Abstract PDF: The tibial condylar fractures are characterized by intra-articular extension of fracture line and associated soft tissue injuries, and could affect knee alignment, stability, adn range of motion after treatments. Therefore, anatomical reduction and rigid internal fixation is mandatory to get satisfactory results. But this method of treatment can not be always possible due to technical dimend of surgical sklls and high risk of postoperative infection. The authors analyzed 43 cases of tibial condylar fractures, which were treated at the orthopaedic department of the Dongguk University Hospital from March 1990 to May 1996. Males were 34, and females were 9. Average age of patients was 41.4 years, and average follow up period was 18 months. The most common causes of injuries were traffic accidents (36 cases), and most common type of fracture was Schatzker type I. associated soft tissue injuries were observed in 21 cases. Treatment methods were chosen by degree of displacement of fracture fragment and associated soft tissue injuries. Conservative treatments were done in 23 cases and operative treatments in 20 cases. Satisfactory results were obtained in overall 32 cases(74%) regardless of the methods of treatment. Unsatisfactory results were observed in patients who had associated soft injuries and significant displacement of fracture. Conclusively, satisfactory results could be obtained in patients with tibial condylar fractures by appropriate selection of treatments according to displacement of fracture and associated soft tissue injuries.
