Latissimus dorsi tendon transfer is a well-established method for treatment of irreparable posterosuperior rotator cuff tears. We report on an anterolateral mini-open technique with a porcine dermal patch augmentation for latissimus dorsi tendon transfer. Use of this technique would result in avoidance of deltoid damage by anterolateral mini-open approach and reduction of failure rate by patch augmentation.

In an open reduction of the mandibular angle fracture, it is crucial to approximate each fracture segment as closer as possible for the reduction of the healing period. In this case report, we proposed a new technique for the mandibular angle fracture. This was designed to minimize the gap between two separated segments using mini-implants and surgical wires. Mini-implants were placed around the fracture line, followed by wire ligation to minimize the fracture gap. And then internal fixation was easily employed with plates and screws. The advantages of this technique were reduced time for operation, the promotion of healing, rapid functional recovery, and few complications.

Purpose: Although surgical arthroscopic repair of rotator cuff has become much more common as surgeons have developed proficient techniques, it is still technically difficult. The purpose of this study was to evaluate the clinical results and the usefulness of mini-open repair in large and massive size tears. Materials & Methods: From January 2000 to December 2004, sixteen patients were treated with mini-open repair. There were 10 male and 6 female patients with the average age of 62.5 years. The size of tear was massive in 4 cases and large in 12 cases. All tears were repaired with metal anchor sutures. The mean duration of follow-up period was 23 months. Postoperative results were evaluated based on American Shoulder and Elbow Society scoring system. Results: Five patients showed excellent results, five good, and two fair in large tears while one patient showed excellent result, one good, and two fair in massive tears. Poor outcome was not seen during the follow-up period. There was no significant relationship between the patient's age and the size of tear, and postoperative results. However, the relationship between the duration of symptomatic period in preoperation and postoperative results showed significant correlation. Conclusion: Mini-open repair combined with the preservation of deltoid and early rehabilitation is clinically useful in large and massive size rotator cuff tear patients treatment.

Purpose: To compare the outcome of patients who underwent rotator cuff repair using all-arthroscopic mini-open repair techniques. Materials and Methods: We retrospectively reviewed 44 patients who underwent either arthroscopic (group I) or mini-open (group II) rotator cuff repair. 23 patients underwent an arthroscopic repair and 21 patients had a mini-open repair. The mean age was 50.4 years in the arthroscopic group and 56.7 years in the mini-open group. The outcomes for the 2 groups were evaluated using ROM, VAS, ASES, UCLA scale. Statistical analysis was performed using correlations, T-test, Paired T-test. The mean follow-up period in the arthroscopic and mini-open groups were 24.1months and 26.1months, respectively. Results: The group I (arthroscopic group) had 2 small-sized tears, 10 medium sized tears, and 11 large sized tears (3~5 cm). The group II (mini-open group) had 1 small sized tears, 8 medium sized tears, and 12 large sized tears. The mean cuff tear size of the group I and Group II were 3.8 cm and 4.2 cm, respectively. At last follow-up periods, ROM and functional scores were improved. In the group I and group II, there were no significant difference in ROM, VAS, ASES, UCLA score. Conclusion: The size of the tear did not produce different results at arthroscopic repair group but larger tear size was associated with a worse outcome in mini-open group. There were no significant clinical results between the arthroscopic and mini-open group.

The purpose of this study was to compare the outcomes between arthroscopir repair and mini-open repair of medium and large rotator cuff tears in which arthroscopic repair was technically unsuccessful. We evaluated 76 patients of full-thickness rotator cuff tears, among them 42 patients had all-arthroscopic and 34 patients had mini-open salvage repairs. Patients who had acromioclavicular arthritis, subscapularis tear, or instability were excluded. There were 39 males and 37 females with mean age of 56 years (range,42 to 75 years). At a mean follow-up of 39 months (range, 24 to 64 months), the results of both groups were compared with regard to the UCLA and ASES shoulder rating scale s. Shoulder scores improved in all ratings in both groups (p > 0.05). Overall, sixty-six patients showed excellent or gr)of and ten patients showed fair or poor scores by the UCLA scale. Seventy-two patients satisfactorily returned to prior activity. Four showed unsatisfactory return. The range of motion, strength, and patient's satisfaction were improved postoperatively. There were no difference in shoulder scores, pain, and activity return between the arthroscopic and mini-open salvage groups (p > 0.05). However, Patients with larger size tear showed lower shoulder scores and less predictive recovery of the strength and function (p < 0.05). Postoperative pain was not different with respect to the size of the tear (p : 0.251). Arthroscopic repair of medium and large full-thickness rotator cuff tears had iln equal outcome to technically unsuccessful arthroscopic repairs, which were salvaged by conversion to a mini- open repair technique. Surgical outcome depended on the size of the tear, rather than the method of repair.

Purpose: To report our experience of treatment of rotator cuff tear and evaluate the mid-term outcome. Materials and Methods: We have performed 50 cases of mini-open rotator cuff repair from March 1996 to March 1999. Male to female ratio was 34：16, the average age 46.5(23∼57) years old, mean follow-up period was 78(62∼93) months. All-arthroscopic repair and open repair cases were excluded. Mean symptomatic period was 12.5(6∼38) months, operation was indicated in cases of no improvement by 6 months of conservative management. Preoperative simple radiographs and Magnetic resonance arthrography were obtained in all cases. We also observed the inflammation, synovitis, thickness of tear and associated pathology intraoperatively. We evaluated pain, function, and range of motion by UCLA score. Results: Overall UCLA score was mean 29.5 points. Excellent 25, good 18, poor 7 cases. Mean pain score was improved 2.6 to 7.5, 44 cases(88%) were improved and 6 cases(12%) were not improved. Mean functional score was improved 3.4 to 8.5, and activity at follow up, 25 cases(50%) were same, 8 cases(14%) were above, 17 cases(34%) were below compared with preoperative level. Mean active forward flexion was preoperative 112° to postoperative 160°, forward flexion strength was improved 3.8 to 4.7. 43 cases(86%) of patients were satisfied at the result, 7 cases(14%) were not satisfied or aggravated. Results: Mini-open rotator cuff repair was effective method in treating rotator cuff tear.

Successful treatment of the non-growing patient with an open bite of either dental skeletal pattern often presents a difficult challenge. The morphologic pattern in anterior open bite is characterized by longer vertical dimensions, an increase in development of the maxillary posterior dento-alveolar structure and a steep mandibular plane. In such cases, molar intrusion would be a good remedy for treatment. This article reports the successful treatment and retention of two anterior open-bite cases. We used orthodontic mini-implants for treatment and a circumferential retainer with posterior bite block or skeletal fixed retainer for retention. The diagnostic criteria and mechanics for appropriate treatment are discussed. Our results suggest that open bite can be reduced successfully with intrusion of molars using orthodontic mini-implants (OMI) without orthognathic surgery, and that circumferential retainer with posterior bite block and skeletal fixed retainer are effective for retention.

Purpose: This study sought to verify the usefulness of mini-implant and surgical steel wire in the treatment of mandibular fracture through the objective identifi cation of the change of bone structure and bone density before and after reduction by evaluating radiological change through fractal analysis when mandibular fracture is treated using mini-implant and surgical wire. Materials and Methods: This study looked at 45 patients (males: 38, female: 7) diagnosed with mandibular fracture in the oral and maxillofacial surgery division of Chung-Ang University Dental Hospital and who received open reduction and intra-osseous fi xation. Result: The average fracture dimension values were higher for the group of the patients who had mini-implants and surgical wire treatment. Conclusion: Based on the results of the study on the usefulness of the reduction technique using mini-implant and surgical steel wire in the treatment of mandibular fracture through the fractal analysis method, the reduction technique using mini-implant and surgical steel wire is regarded as an effective method of minimizing the gap between mandibular fracture fragments.
