- PURPOSE
The purpose of our study is to compare the radiographic and clinical outcomes with respect to acromioclavicular (AC) joint dislocation depending on the surgical method: Hook plate (HP) versus TightRope (TR).
MATERIALS AND METHODS
Between May 2009 and May 2012, 51 patients with Rockwood type III-V lesions received clinical and radiographic follow-up. Patients were divided into two groups according to the surgical methods (HP: n=32; TR: n=19). Radiological follow-up included comparative coracoclavicular distance (CCD) measurements as a percentage of the uninjured shoulder. For clinical follow-up, a standardized functional shoulder assessment with the Constant score, University of California at Los Angeles (UCLA) score, and Korea shoulder score (KSS) were carried out.
RESULTS
Comparing the functional results, no differences were observed between the two groups (Constant score: HP, 78.5; TP, 81.4; UCLA score: HP, 29.2; TP, 29.9; KSS: HP, 79.2; TP, 80.7). Time to restoration of the range of motion (ROM) above shoulder level was longer in the HP group than in the TR group. However, the ROM at 1 year postoperation and final follow-up revealed similar results between the two groups. The AC joints were well reduced in both groups, the CCD increased to 44.7% in the HP group and to 76.5% in the TR group at the final follow-up; however, no one was significantly superior to the others. Furthermore, there were 8 cases (25.0%) and 5 cases (26.3%) of AC joint arthritis in the HP group and TR group, respectively. However, the observed AC joint arthritis has a poor correlation between clinical symptom and radiological results in both groups.
CONCLUSION
Both HP and TR fixation could be a recommendable treatment option in acute unstable AC joint dislocation. Both groups showed excellent radiologic and functional results at the final visit. Moreover, there was no significant difference in statistics, except for the time to restoration of ROM above shoulder level.

- 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.
