Purpose: The objective of this study was to examine the clinical results and effectiveness of resection arthroplasty for correction of lesser toe deformity. Materials and Methods: From January 2000 to November 2012, 92 cases of resection arthroplasty for lesser toe deformity were reviewed. Hammer toe was the most common type of deformity, accounting for 44 toes (33 patients). Hallux valgus was the most common comorbid illness. Second toe was the most commonly affected toe and proximal interphalangeal joint was the most common location of resection arthroplasty (69 toes, 75.0%). We also analyzed the alignment of phalanges using the last follow-up weight bearing radiographic image. The analysis included clinical evaluation with American Orthopaedic Foot and Ankle Society (AOFAS) score as well as subjective satisfaction. Results: Flexor tenotomy (19 cases) was the most common combined surgery. Floating toe (4 cases) was the most common complication. The last follow-up alignment of phalanges was better than good in 71 toes (77.2%) in anteroposterior view and in 69 toes (75.0%) in lateral view. Sixty one cases (85.9%) resulted in better satisfaction than 'good' and the final average AOFAS score was 87.4. Conclusion: Resection arthroplasty is a valuable surgical option for treatment of lesser toe deformity, with high patient satisfaction, easy surgical technique and remarkable correction of deformity.

Motion of the metatarsophalangeal joints is essential for the normal gait. Therefore it is important to recover the motion of normal joint in the treatment of stiffness of the metatarsophalangeal joints. However, there have been no report about the treatment of stiffness of the four lateral lesser metatarsophalangeal joints yet. We report an experience that good clinical and radiographic results were obtained after resection arthroplasty for the post-traumatic stiffness of the four lateral lesser metatarsophalangeal joints.

Hallux valgus, or a 'bunion', is a deformity characterized by lateral deviation of the big toe. Surgery is indicated when conservative treatments have failed to result in improvement of symptoms. Operative techniques include simple bunionectomy, distal soft tissue procedure, phalangeal osteotomy, metatarsal osteotomy (distal, shaft, or proximal), arthrodesis (metatarsophalangeal or tarsometatarsal), or resection arthroplasty. Good results are expected when the selection of operative technique is based on the correct treatment principle.

Purpose: We assess the mid to long term follow up results of arthrodesis of the first metatarso-phalangeal (MTP) joint and resection arthroplasty of the lesser toes in rheumatoid arthritic forefoot deformity. Materials and Methods: Between 1998 to 2001 year, 25 cases (18 patients) rheumatoid forefoot deformities were surgically corrected. Follow up period was 83 months (range, 63 to 90 months). The clinical outcome was evaluated using subjective satisfaction and AOFAS score. The radiological measurements were hallux valgus angle, first and second intermetatarsal angle, second metatarso-phalangeal angle (MTP-$2^{nd}$ angle). Results: Subjective satisfaction was 76%. AOFAS score improved from 37 to 73. The hallux valgus angle improved from preoperative $39^{\circ}$ ($27{\sim}64^{\circ}$) to $14^{\circ}$ ($4{\sim}34$) at the last follow up. The intermetatarsal angle were preoperative $13^{\circ}$ ($6{\sim}22^{\circ}$) to $11^{\circ}$ ($3{\sim}13^{\circ}$) at the last follow up, The MTP-$2^{nd}$ angle were preoperative $24^{\circ}$ ($9{\sim}47$) to last follow up $15^{\circ}$ ($2{\sim}39^{\circ}$) respectively (p>0.05). Complication was intractable callus 10 cases, Interphalangeal arthritis 5 cases. Conclusion: Mid to long term outcomes rheumatoid forefoot reconstruction by first MTP arthrodesis and resection arthroplasty of lesser toes results a satisfaction and pain relief.

Background: Temporomandibular joint (TMJ) ankylosis during early childhood may lead to disturbances in growth and facial asymmetry and to serious difficulties in eating as well as in breathing during sleep. The purpose of this study is to describe the effectiveness of an interocclusal splint (IOS) for active mouth opening exercises in the treatment of TMJ ankylosis. Methods: A total of nine patients with 13 instances of TMJ ankylosis from 2008 to 2010 were included in this study, of which five patients were male and four patients were female. Five patients demonstrated unilateral ankylosis, while five patients showed bilateral symptoms. Ankylosed mass resection with coronoidectomy, fibrotic scar release, and resection of stylohyoid ligament calcification was performed with gap arthroplasty without an interpositional graft, and all patients were assessed for maximum mouth opening (MMO) during a mean 6.6-year follow-up period. Results: All patients were subjected to postoperative mouth opening exercises from the day of the operation with the help of an IOS, which was based on an impression taken during surgery. All patients were sufficiently comfortable moving their mandible according to the IOS's guiding plane and impingement, and satisfactory results were achieved, in which MMO was improved by 35 mm more than 6 years after surgery. Conclusions: Complete and adequate resection of the ankylosed mass and postoperative active mouth opening exercises are essential in the treatment of TMJ ankylosis. Moreover, a more comfortable mouth opening guide and interdigitation can be achieved using an IOS, and newly organized fibrosis in the gap space between the newly made resected condylar head and temporal fossa can be suggested.

Controversies exist regarding the treatment options for the end-stage arthritic change in the lateral tarsometatarsal joints. Arthrodesis has been frequently performed, but has a disadvantage of sacrificing a mobile joint. Resection arthroplasty also gained its popularity, especially in the patients with Rheumatoid arthritis, but possible hypermobility can lead to deformity. We report a successful clinical outcome of a patient with Rheumatoid arthritis in the 4th, 5th tarsometatarsal joints treated with tendon interpositional arthroplasties.

Purpose: To describe the recent clinical results and complications of total elbow arthroplasty based on the literature review. Materials and Methods: The indications of total elbow arthroplasty include rheumatoid or inflammatory arthritis, posttraumatic arthritis, anklylosed elbow, tumor resection which cannot recover elbow function by other reconstructive procedures, and comminuted distal humerus fracture in elderly patients. Complications are aspetic loosening, infection, prosthesis fracture, periprosthetic fracture, ulnar neuropathy, ectopic ossification, triceps insufficiency, dislocation, and bushing wear. Results and Conclusion: Mean 10 year survival rate following total elbow arthroplasty has been reported 85% on the basis of revision. The prognosis in patients with an inflammatory arthritis is reported to be best, and loosening rate in patients with a posttraumatic arthritis tends to be high. Complication rate is known to be higher than that of other joint arthroplasty. In particular, deep infection occurs in 3~5% of the patients. Total elbow arthroplasty provide satisfactory results when it is performed properly in selected patients who have an elbow joint with irreversible dysfunction and low level activities.

Purpose : To evaluate the effect of radial head resection on longevity in nonconstrained total elbow arthroplasty, Materials and Methods : The results of 20 cases of radial head replaced Pritchard ERS and 18 cases of radial head excised Kudo elbow was followed for 6 to 16 years, 10.6 years in average. The rate of loosening, osteolysis, radial head subluxation, joint dislocation and valgus deformity were compared between the two groups. Results'There was no exaggerated cubitus valgus in Pritchard ERS group. However there developed one case of delayed subluxation of radial head occurred in 6 years postoperatively, one case of loosening, and one case of sponta- neous fracture of humeral shaft due to osteolysis. In Kudo elbow group,5 cases (27.8%) showed exaggerated valgus deformity with instability. There were one case of loosening and one case of delayed dislocation occurred in a year postoperatively. Conclusion : The most clear feature of Kudo elbow was exaggerated cubitus valgus. However, the ostolysis was developed in both groups and there was no difference in rate of the other complications between the two groups.

Purpose: We compared the results of total ankle arthroplasty in patients with preoperative varus deformity of more than $20^{\circ}$ with those of patients with varus deformity less than $20^{\circ}$. Materials and Methods: From January 2005 to January 2013, 9 ankles with preoperative varus deformity of more than $20^{\circ}$ (varus group) and 31 ankles with varus deformity less than $20^{\circ}$ (control group) underwent total ankle arthroplasty. Clinical results were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) score, and radiographic results were assessed using tibiotalar varus angle in standing anteroposterior radiographs taken preoperatively and at the last follow-up. Results: The mean duration of clinical follow-up was 42.8 months (14~60 months). The AOFAS score was improved by a mean 47.0 points in the varus group and 37.6 points in the control group. Statistically significant difference was observed between the two groups (p=0.041). Tibiotalar varus angle measured at the last follow-up radiograph was $2.5^{\circ}$ in the varus group and $1.0^{\circ}$ in the control group and the difference was not statistically significant (p=0.820). Conclusion: Satisfactory clinical and radiographic results can be achieved in patients with varus deformity more than $20^{\circ}$ by precise bone resection and soft tissue release.

Giant cell tumor is most frequently found in juxtaarticular region, and difficult to treat because of local recurrence. Although primary resections reduce recurrence, the joint function will be markedly impaired. Techniques involving physical adjuncts(high speed burr and electric cauterization), acrylic cement or en bloc resection with VFG(vascularized fibular graft) have been employed to reduce local recurrence. From October 1984 to April 1994, twenty-nine patients diagnosed as giant cell tumor were treated at department of Orthopaedic Surgery, School of Medicine, Kyung Hee University. There were eleven men and 18 women, ranging in age from 17 to 52 years(mean: 34 years). The average follow-up period was four years and five months. The location of the lesion was around the knee in 15, distal radius in three, femoral head in three, and others in eight patients. Fifteen patients around the knee joint were treated with several modalities; curettage with bone graft in five, curettage with cement filling in three, curettage with bone graft and physical adjuncts in five, en bloc resection with VFG in one and en bloc resection with arthroplasty in one patient. The functional results, according to the Marshall's knee score, were excellent in one, good in two, and fair in two after the curettage with bone graft, good in three after the curettage with bone cement filling, excellent in one, good in four after the curettage with bone graft and physical adjuncts, and good in two after the en bloc resection with VFG or arthroplasty. Three patients had local recurrence among 15 patients with giant cell tumor around knee. Vascularized fibular graft around wrist joint provided good functional restoration without local recurrence in all three patients who had giant cell tumor in distal radius. Although there is no statistical significance, it seems that curettage with bone graft using physical adjuncts or acrylic cement reveals better results than simple curettage with bone graft. Excellent functional result were obtained without local recurrence by using vascularized fibular graft after en bloc resection.
