Penetration of Joints by Screws on Anterior Process of Calcaenus: Choong Hyeok Choi, Il Hoon Sung, Bong Geun Lee, Doo Jin Paik, Dong Won Kim; J Korean Fract Soc 2004;17(3):257-260. Published online July 31, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.3.257

Abstract PDF: PURPOSE
This study was performed to determine the involvement of joints by screws, inserted on the anterior process of the calcaneus, using cadaveric specimens.
MATERIALS AND METHODS
An L-shaped lateral incision was performed on 32 embalmed feet (16 cadavers). An H-plate was applied on lateral wall of the calcaneus and it's anterior margin was located at 4 mm posterior to the lateral margin of the calcaneocuboidal joint. 3.5 mm cortical screws were inserted perpendicularly to the lateral calcaneal wall through the plate. Each calcaneus was dissected and taken out from the foot, and whether the tips of screws penetrated joints on the anterior process was evaluated.
RESULTS
11 (17.2%) of 64 screws, inserted on the anterior process, penetrated joints. Among them, seven screws involved the calcaneocuboidal joint and four screws penetrated the anterior facet of the subtalar joint. In two cases, both joints were penetrated by screws.
CONCLUSION
This study shows that joint surfaces could be penetrated by screws inserted from the lateral surface on the anterior process of the calcaneus. Care should be given to selecting the length and insertional angle of screws. Intraoperative radiography would be needed to observe the articular surface on the anterior process, when screws were inserted to the anterior process close to the calcaneocuboidal joint.

The Clinical Results in Compression Plate Fixation with Autogenous Cancellous Bone Graft for Humerus Diaphyseal Nonunion: Kwang Hyun Lee, Seong pil Lee, Hyung Jong Kim, Bong Geun Lee, Joo Hak Kim; J Korean Fract Soc 2004;17(2):90-94.

Abstract PDF: PURPOSE
A The purpose of this retrospective study was to evaluate the results of compression plating and autogenous iliac bone graft in the management of humeral diaphyseal nonunion.
MATERIALS AND METHODS
Twenty patients who underwent the surgical treatments between May. 1998 and May. 2002 were included in this study. Nine of them are males and the others are females. The average age of them, when they was on operation, was 45 years. The symptoms lasted 23 months on average. They have been followed up for 33 months at an average. Treatment of nonunion consisted of resecting the atrophic nonunion, shortening the bone, apposing bleeding diaphyseal surface. Rigid fixation was then achieved using a compression plate and autogenous bone graft.
RESULTS
Solid bony union was achieved in all patients. In one patient, the bone was not healed at the first operation of plating and autogenous bone graft, but achieved union after the use of intramedullary nailing. In another patient, because of infected nonunion, we achieved union after several surgical debridement and stabilization by internal fixation.
CONCLUSION
This study documents that compression plate fixation with autogenous cancellous bone graft is a viable option with predictable and satisfactory results for humerus diaphyseal nonunion.
