Bone-anchored hearing aid is a hearing assisting technology that raise the hearing level via bone conduct and is also the only implantable hearing assisting device working by bone conduct. Because of the superior performance and simple process of implantation, it brings gospel to the patients who are not fitting the air conducting hearing devices. This article is a review of bone-anchored hearing aid from 6 aspects, including history, principle, indication, consulting, surgery and complication.

PURPOSE: For an isolated tear of the subscapularis tendon, the presented technique using a subclavian portal provides both a good angle for anchor placement and sufficient space for managing the upper portion of a subscapularis tendon tear. MATERIALS AND METHODS: The conventional method needs 2 additional portals for traction, debriding the footprint and anchor fixation for repair. The presented technique requires only an anterior portal for suture management and a subclavian portal without cannula for suture anchoring and placement of suture hooks. RESULTS: The two suture limbs of the anchor can be placed on the subscapularis tendon by the switching technique and these limbs are repaired sequentially. CONCLUSION: This technique is simple and reproducible and it can be applied to partial tears and minimally retracted subscapularis tears.

Ankle sprain secondarily leads to chronic lateral ankle instability in 20%-30% of cases. Many surgical procedures have been presented for lateral ankle instability; however, controversy remains regarding the ideal surgical option. The Brostrom procedure or its modifications have been widely used; however, they have some limitations for the instabilities of over-weight, physically high demanding patients, generalized ligamentous laxity, and especially for significantly deficient or attenuated ligaments. This article reports on the difference between the bone tunnel technique and the suture anchor technique of the modified Brostrom procedure, and also provides a review of several recent debates.

Medial meniscal root tears have been repaired using various methods. Arthroscopic all-inside repair using a suture anchor is one of the popular methods. However, insertion of the suture anchor into the proper position at the posterior root of the medial meniscus is technically difficult. Some methods have been reported to facilitate suture anchor insertion through a high posteromedial portal, a posterior trans-septal portal, or a medial quadriceptal portal. Nevertheless, many surgeons still have difficulty during anchor insertion. We introduce a technical tip for easy suture anchor insertion using a 25° curved guide and a soft suture anchor through a routine posteromedial portal.

PURPOSE: This study examined the outcomes of reconstruction of the coracoclavicular ligaments with using two suture anchors and performing coracoacromial ligament transfer in patients with acromioclavicular dislocation. MATERIAL AND METHODS: Forty patients with complete acromioclavicular dislocation were included in this study. According to the preoperative radiographs, 5 patients with AC dislocations were diagnosed as type III, 4 patients as type IV and 31 patients as type V. Two 3.5mm suture anchors with four strands of nonabsorbable sutures were separately placed on the anterolateral and posteromedial portion of the base of the coracoid process to stabilize the distal clavicle. The coracoacromial ligament was then transferred to the undersurface of the distal end of the clavicle for augmentation. RESULTS: At a mean follow-up of 28 months, the average Constant score improved to 97 points. All the patients returned to normal life at an average of 3.2 months postoperatively. At the last follow-up, 37 patients achieved anatomical reduction and three patients showed complete redislocation. However, the clinical results of the patients with redislocation were satisfactory. CONCLUSION: Anatomical coracoclavicular reconstruction using two suture anchors and coracoacromial ligament transfer for treating complete acromioclavicular dislocation is a safe, effective procedure for restoring a physiologically stable acromioclavicular joint.

The arthroscopic rotator cuff repair is now considered a mainstream technique with highly satisfactory clinical results. However, concerns remain regarding healing failures for large and massive tears and high revision rate. In recent decades, various repair strategies and construct configurations have been developed for rotator cuff repair with the understanding that many factors contribute to the structural integrity of the repaired construct. The focus of biomechanical test in arthroscopic repair has been on increasing fixation strength and restoration of the footprint contact characteristics to provide early rehabilitation and improve healing. These include repaired rotator cuff tendon-footprint motion, increased tendon-footprint contact area and pressure, and tissue quality of tendon and bone. Recent studies have shown that a transosseous tunnel technique provides improved contact area and pressure between rotator cuff tendon and insertion footprint, and the technique of using double rows of suture anchors to recreate the native footprint attachment has been recently described. The transosseous equivalent suture bridge technique has the highest contact pressure and fixation force. In this review, the biomechanical tests about repair techniques of rotator cuff tear will be reviewed and discussed.

PURPOSE: The purpose of this study is to compare the clinical outcome of excision versus osteosynthesis of type II accessory navicular performed by a single surgeon. MATERIALS AND METHODS: Cases of 14 feet treated with excision and 13 feet by osteosynthesis for type II accessory navicular of 25 patients from 2002 to 2009 were included in this study. Radiological measurements and American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scale was evaluated. RESULTS: AOFAS midfoot scale of both excision and osteosynthesis groups at last follow-up showed improvement from pre-operation. However, there was no statistical difference in AOFAS midfoot scale and subjective satisfaction between the two groups at last follow-up. In detail of AOFAS midfoot scale, pain and footwear requirements showed statistically favorable results for the excision group, while activity limitation and support showed statistically favorable results for the osteosynthesis group. Subjective recovery time returning to daily activities and starting rehabilitation exercise were 14.6 weeks in the excision group and 13.7 weeks in the osteosynthesis group (p=0.025, Mann-Whitney). Suture anchor loosening was observed in one case in the excision group and non-union in two cases in the osteosynthesis group. CONCLUSION: Both excision and osteosynthesis are favorable surgical methods, but each method has advantages and possible complications such as suture anchor loosening or non-union. Surgeon's preference, patient's chief complaint, specific needs of patient after the operation and consideration of the size of accessory navicular can be a criteria to consider when selecting a surgical method.

PURPOSE: We studied the short term results of the arthroscopic repair of 1B type triangular fibrocartilage complex (TFCC) tear using a knotless suture anchor. METHODS: We evaluated 23 patients who underwent all-inside arthroscopic TFCC repair using a knotless suture anchor. The average follow-up duration was 6.6 months (range, 3-10 months). Mean duration of symptom was 10.9 months (range, 1 week-7 years). The arthroscopic finding documented 15 type 1B, 2 1B with 1D, and 6 1B with 2C lesions. All showed the positive hook test. The concomitant pathologies were 16 scapholunate injuries and 10 lunotriquetral injuries. TFCC tears were repaired by the knotless suture anchor. The Wafer procedure was done for 2C lesions. RESULTS: According to Mayo modified wrist score, the result was excellent in 4, good in 14 and fair in 5. Nineteen patients (82.6%) could return to his job or hobby. CONCLUSION: The all-inside arthroscopic repair using knotless suture anchor for TFCC 1B tear can provide good results. The appropriate management should be done for the concomitant pathologies for the better results.

The purpose of this study was pertinent design of the framework of the fixed bone anchored bridge using implants in the edentulous mandible through analysis of stress distribution by the three dimensional finite element analysis method. The results were as follows: 1. The L-shaped framework was favorable in restoring the edentulous mandible by implants and fixed bone anchored bridge. 2. The structure of the framework should be designed to endure the occlusal load because of stress concentration at the most distal abutment of the framework. 3. The stress at the distal implant where cantilever starts was twice as much as that of other portions. 4. Compressive stress was generated on the framework of the mesial side of the distal implant and extrusive force was induced to the mesially positioned implants. 5. The height of vertical plate was high as possible as can be to distribute stresses concentrating bucco-lingually and labio-lingually in the framework between abutments, 6. Reinforcement of the horizontal plate thickness was needed because stress was loaded more on the horizontal plate than on the vertical plate of the framework. 7. Lengthening of the vertical plate can compensate for any limitations in horizontal plate width.

While a sprain of the hamstring muscle is relatively common in athletes or those who participate in physically active sports, a complete rupture of the proximal hamstring is relatively rare. A rupture of the long head of the biceps femoris without rupture of the semimembranosus and semitendinosus muscles has rarely been reported. In this study, we saw relatively favorable outcomes after reattachment with a suture anchor at the ischial tuberosity in two patients who had a rupture of the long head of the biceps femoris.
