Surgical treatments for arthritis in the first metatarsophalangeal joint include arthrodesis, interposition arthroplasty using silicone or meniscus cartilage, and rarely arthroplasty. Although arthrodesis was performed successfully, pain can persist if the angle of fusion was inappropriate. Interposition arthroplasty can be tried for the treatment of persisting pain after the arthrodesis. Interposition arthroplasty using tensor fascia lata is known that has low risk of adhesions and easy to harvest. Compared to autologous grafts, grafting rates is high and low risk of rejection additionally. Herein, we report a successfully managed arthritis with severe pain with interposition arthroplasty using tensor fascia lata after a failed metatarsophalangeal joint arthrodesis.

Background This study has been conducted with the aim of evaluating modified T-plate interpositional arthroplasty. Methods A prospective comparative study in patients admitted with temporomandibular joint ankylosis. Ankylotic temporomandibular joint arthroplasty included condylectomy gap arthroplasty in 7, temporalis muscle flap interpositional arthroplasty in 8, and modified T-plate interpositional arthroplasty in 13 cases. The patients were followed for three years. Collected data were tabulated and subjected to Fisher's exact test, chi-square test and probability estimation. Results A significant increase in interincisal distance of 32 mm was seen in 12 (92.31%) patients in the T-plate interposition group, in 2 (25%) cases of the temporalis muscle flap interposition group, and in 1 case (14.28%) of the condylectomy group at 12, 24, and 36 months. Re-ankylosis was observed in 1 case (9.69%) of the T-plate interposition group, while as it was observed in 4 (50%) cases in the temporalis muscle flap interposition group and 4 (57.14%) cases in the condylectomy group, and these differences were statistically significant. Conclusions Our clinical experience with the use of the T-plate over the past 5 years has been encouraging, and our physiotherapy technique is quite simple. Even illiterate parents can assess it easily. Hence, we recommend this easy technique that does not damage the temporalis muscle for the management of temporomandibular joint ankylosis.

Unilateral bony ankylosis of temporomandibular joint is not extremely rare. Treatment in all cases should be surgical. Considerable difficulty has been encountered by surgeons in the judgment of the planning of the treatment for anklosis; either by gap arthroplasty or by interposition arthroplasty. A recent review of the literautre reveals that many authors reported more of the interposition arthroplasty treatment because of no recurrence and the excellent results obtained. This 22-year-old Korean female, who had suffered from unilateral temporomandibular joint recurrent anklosis, was received an operation of ramus osteotomy followed by interpositional arthroplasty with using of thin gold plate. She formerly was received condylectomy twice at the age of 8 and 9, under the diagnosis of unilateral bony ankylosis due to trauma. My experience with alloplasty in unilaterally recurrent ankylosed T-M joint is presented here for her general and oral functional condition proved to be satisfactory after 4 years follow-up.

Objectives: The objective of this study was to highlight the role of lateral arthroplasty along with interposition of the buccal fat pad (BFP) in the management of Sawhney type III temporomandibular joint (TMJ) ankylosis. Materials and Methods: Ten patients with TMJ ankylosis (7 unilateral and 3 bilateral, total of 13 joints) were treated with lateral arthroplasty and BFP interposition. The bony bridge of the ankylotic mass on the lateral aspect was resected, leaving a distance of 1.5 to 2.0 cm from the base of the skull to the neck of the condyle. The condyle was left intact. Coronoidectomy was performed on the ipsilateral side via the same approach in all cases. The inter-incisal opening was measured at that time, and if it was less than 35 mm, contralateral coronoidectomy was performed by using the intra-oral approach. After satisfactory inter-incisal mouth opening (${\geq}35mm$) was achieved, the TMJ surgical site was revisited, and BFP was retrieved and used to cover the lateral aspect of the medially placed condyle. Results: With lateral arthroplasty, the medially displaced condyle can be left in-situ to maintain the mandibular ramal height and function and to act as a growth center in children. Interposition of the BFP prevents reformation of the lateral bony bridge that was removed. Conclusion: Lateral arthroplasty along with interpositioning of the BFP is a novel technique for managing Sawhney type III ankylosis that achieves management goals while avoiding complex and advanced reconstructive surgical procedures.

The 4th and 5th metatarsocuboid joint arthritis causes moderate functional deficit during walking. It is difficult to obtain good results with conservative treatment. The arthrodesis of the affected joints can be a possible surgical option, but with a limited success. We report two cases of the 4th and 5th metatarsocuboid joint arthritis managed with anchovy tendon interposition arthroplaty.

Interpostion arthroplasty with allograft has been known as a useful option for the shoulder arthropathy, but it has a limitation to immune response. We performed the pectoralis major muscle transfer for shoulder arthropathy. From January 2007 to December 2007, we performed the pectoralis major muscle transfer in 2 patients. They were 1 man and 1 woman, and the mean age of the patients was 70 years (range, 65 to 75). The average follow-up after surgery was 13 months (range, 12 to 14). We analyzed the clinical results by the American Shoulder and Elbow Surgeons (ASES) Score, and evaluated the pain by Visual Analogue Scale. The level of pain reduced from a preoperative average of 10 to a postoperative average of 1. The ASES scores increased from a preoperative mean of 9 to a postoperative mean of 58. These results indicated that interposition arthroplasty with the pectoralis major muscle transfer is a reliable treatment method for the shoulder arthropathy improving shoulder pain, and patient satisfaction.

Bilateral true bony ankylosis of temporomandibular joint is extremely rare. Treatment in all cases should be surgical. Considerable difficulty has been encountered by surgeons in the judgment of the planning of the treatment for ankylosis : either by gap arthroplasty treatment because of no recurrence and the excelent results obtained. I performed an osteoarthrotomy and interposition arthroplasty bilaterally, using combined materials consisting of acrylic resin and gold plate. My experience with alloplasty in ankylosed temporomandibular joints is pressented.
