Impaired Bone Healing Metabolic and Mechanical Causes: Sam Guk Park, Oog Jin Shon; J Korean Fract Soc 2017;30(1):40-51. Published online January 31, 2017; DOI: https://doi.org/10.12671/jkfs.2017.30.1.40

Non-union is one of the most devastating complications after fracture fixation. It usually results in prolonged treatment duration and unpredictable results. We reviewed the literature to identify recent information regarding the following: risk factors of nonunion; mechanical risk factors, including fracture gap width and stability, osteonecrosis and healing mechanism, osteoporotic fracture and fixation method, the characteristics of fracture, soft tissue injury, local infection, and multiple fractures; as well as the metabolic risk factors, including age, comorbidities, smoking, alcoholism, and medications. The technique and devices for fracture treatment have been developed, and treatments of nonunion are evolving according to the enhancement of our understanding of nonunion. Clinicians should refer to the risk factors and advancements while developing a treatment plan.

The Mid-Term Result after Osteosynthesis of Intra-Articular Fractures of Distal Femur: Sam Guk Park, Jeong Jae Moon, Oog Jin Shon; J Korean Fract Soc 2016;29(4):242-249. Published online October 31, 2016; DOI: https://doi.org/10.12671/jkfs.2016.29.4.242

Abstract PDF

PURPOSE
This study was to evaluate the radiological and clinical mid-term results and the presence of post-traumatic osteoarthritis after osteosynthesis in patients under the age of 50 years undergoing osteosynthesis for distal femur intra-articular fractures (AO/OTA 33-B & C) from high-energy trauma.
MATERIALS AND METHODS
Between January 2008 and January 2013, a total of twenty-one patients with more than three years of follow-up were enrolled. Recovery of the alignment of the lower extremity, union period, and the presence of post-traumatic osteoarthritis were confirmed by follow-up radiographs. Clinically, the range of motion, pain on fracture lesion, and Knee Society score (KSS) were evaluated.
RESULTS
The average duration of union was 18.2 weeks (10-28 weeks), and the alignment of the lower extremity was within normal range in all patients. Seven patients showed post-traumatic osteoarthritis at the final follow-up after more than three years. The presence of post-traumatic osteoarthritis was associated with the classification of fractures, coronal plane fracture, and age. The average range of motion, knee score among KSS, and function score at the last follow-up were 128.7Â°, 86.1, and 85.1, all showing a greater improvement when compared with the one-year follow-up scores.
CONCLUSION
The mid-term result was radiologically and clinically satisfactory. Furthermore, only 33.3% of patients showed a slight progress of post-traumatic osteoarthritis, which critically effects the prognosis.

Medial and Lateral Dual Plate Fixation for Osteoporotic Proximal Humerus Comminuted Fracture: 2 Case Reports: Sam Guk Park; J Korean Fract Soc 2016;29(1):61-67. Published online January 31, 2016; DOI: https://doi.org/10.12671/jkfs.2016.29.1.61

Abstract PDF

Some proximal humeral fractures in elderly patients are accompanied by medial metaphyseal comminution and quality of the bone is so poor that head preserving osteosynthesis seems to be amenable. In cases of medial metaphyseal comminution, lateral locking compression plate (LCP) fixation also has a tendency to become a matter of screw cut out or loss of fixation. The author reports on successful treatment of two osteoporotic proximal humeral fractures combined with medial meta-physeal comminution, with application of additional direct medial supporting plate fixation. Medial plate fixations were added when the fractures were still unstable after the conventional lateral LCP fixation and anterior circumflex humeral arteries had been ruptured before. The fixations were stable enough to start exercise immediately after surgery. The inclinations of the humeral neck were not changed until the last follow-up and clinical results were satisfactory without humeral head osteonecrosis which was a concern.
