OBJECTIVE: Metatarsophalangeal joint is an important joint for daily weight-bearing walking. Osteoarthritis, osteochondrosis of the metatarsal head, rheumatoid arthritis can often cause the destruction of 2-5 metatarsophalangeal joint, leading to pain, limited joint movement and toe deformities, severely affecting the forefoot function. The purpose of this study is to report the results of middle-long term follow-up after performing Swanson double-stem silicon implant arthroplasty in patients with diseases of 2-5 metatarsophalangeal joint. METHODS: From January 2010 to October 2015, 21 patients with 2-5 metatarsophalangeal joint replacement were performed with Swanson double-stem silicone prosthesis. In the study, 16 cases were successfully followed up, 2 men and 14 women with an average age (66.7±5.5) years. There were 9 cases diagnosed with rheumatoid arthritis, 5 cases with severe osteoarthritis and 2 cases with osteochondrosis of the metatarsal head. The American Association of foot and ankle surgery Maryland foot scoring system and visual analogue score (VAS) were used to evaluate the walking function, metatarsophalangeal joint mobility and pain degree before and after surgery. RESULTS: The follow-up time ranged from 17 months to 5 years, with an average of 3.2 years. According to Maryland foot scoring system of the American Association of foot and ankle surgery, the preoperative score was (60.69±6.12) points and postoperative score was (88.13±5.84) points. Range of motion of metatarsophalangeal joint: preoperative: back extension 5.4°±3.1°, plantar flexion 4.4°±2.7°; postoperative: back extension 15.7°±4.5°, plantar flexion 12.2°±4.3°, the motion of 2-5 metatarsophalangeal joint after operation was significantly improved compared with that before operation (P < 0.01). The preoperative VAS was (6.8±0.9) points and the last follow-up was (2.3±0.8) points, the pain symptom of metatarsophalangeal joint was improved obviously after operation. The postoperative score was significantly higher than the preoperative score according to Maryland foot scoring system (P < 0.01), the excellent rate was 81.3%. CONCLUSIONS With the advantages of alleviating pain, preserving the length and alignment of metatarsophalangeal joint, improving the function of walking, and correcting the deformity, Swanson double-stem silicon implant arthroplasty is a reproducible and safe option for the reconstruction of the 2-5 metatarsophalangeal joint. However, there is still some probability of adverse reactions and still room for improvement.

Facial dimple creation is a simple surgical procedure. Nonetheless, several complications can occur. Actinomycosis is a rare chronic granulomatous infection caused by Actinomyces species. Some conditions that can cause actinomycosis are trauma, oral surgery, and poor dental hygiene. We report a case of actinomycosis that developed on a created facial dimple. A 51-year-old woman presented with a palpable mass on her left cheek that was approximately 1 cm in size. She had undergone facial dimple-creating surgery on both perioral areas at a local clinic 12 years previously. She had not experienced any problems until she was diagnosed with rheumatoid arthritis and diabetes mellitus about 2 years previously, for which she took leflunomide and methotrexate. The mass was completely excised through an intraoral approach. The specimen was grossly described as a gray-yellow cystic mass containing non-absorbable suture material. The filamentous nature of the Actinomyces organisms was observed in dark-stained foci on a histologic examination, confirming the diagnosis of actinomycosis. Indwelling non-absorbable suture materials may increase the risk for opportunistic infections, such as actinomycosis, in immunocompromised patients. Therefore, plastic surgeons should be aware of a patient's general hygiene, immune condition, and medical history when using these materials.

INTRODUCTIONPatients with rheumatoid arthritis (RA) and osteoarthritis (OA) may require total hip replacement (THR) or total knee replacement (TKR). The present study aimed to compare the demographic characteristics and medical costs of RA and OA patients from Taiwan who underwent either THR or TKR.

METHODSThe medical records of patients who had undergone THR or TKR from 1 January 1996 to 31 December 2010 were obtained from the Taiwan National Health Insurance Research Database (NHIRD). In all, we found 49 and 146 RA patients who received THR and TKR, respectively, and 1,191 and 6,574 OA patients who received THR and TKR, respectively. The gender, age, Charlson comorbidity index (CCI), hospital grade, age at registration in the catastrophic illness dataset, and medical utilisation costs of the different groups were compared.

RESULTSThere were statistically significant differences in age, CCI score, drug costs and surgery costs between RA and OA patients. Joint replacement incidence was lower in RA patients than in OA patients, and among patients who underwent THR, total medical costs incurred were higher for RA patients than OA patients. RA patients who underwent THR incurred a significantly greater total medical utilisation cost in the outpatient department (3 months before surgery and 12 months after surgery) than OA patients who underwent THR.

CONCLUSIONAnalysis of Taiwan NHIRD with regard to patients who had undergone either THR or TKR indicated that RA patients were younger than OA patients, and that significantly more medical resources were used for RA patients before, during and after hospitalisation for these procedures.

OBJECTIVETo investigate the correct method of bone resection and posterior capsular soft tissue releasing in total knee arthroplasty (TKA) for the patients with rheumatoid arthritis with stiff knee in flexion.

METHODSFrom November 2009 to January 2012,15 patients with rheumatoid arthritis with stiff knee in flexion underwent primary TKA and releasing of the posterior soft tissues. There were 7 males and 8 females,aged 22 to 75 years old (58.7 years old on average). The preoperative range of movement(ROM) was (3.2 ± 1.7)°. According to Knee Society score (KSS) criterion, the preoperative clinical score was 23.3 ± 12.5 and functional score was 35.2 ± 9.8. Based on the correct osteotomy, effective releasing of posterior structures was used for different degrees of flexion contracture during the TKA procedure.

RESULTSAll the patients were followed up, and the average duration was 2.3 years (1.6 to 3 years). At the latest follow-up,the KSS clinical score was 81.7 ± 6.5 and functional score was 82.8 ± 9.3. The flexion and extension ROM of the knee joint was (103.5 ± 13.1). Three knees remained 50 flexion contracture deformity, but the function of the affect knees was good.

CONCLUSIONThe effective releasing of the soft tissue of posterior capsule is a major management for correction of the flexion contracture in TKA. The correct releasing of posterior structure can not only achieve fundamental gap of TKA but also effectively avoid bone over-resection.

OBJECTIVETo compare the early clinical outcomes of primary total knee arthroplasty in the valgus knee between mobile-bearing prosthesis and fixed-bearing prosthesis.

METHODSFrom January 2011 to December 2013, 17 patients (23 knees) treated by the same surgeon were selected for a retrospective study in the First Hospital of Jilin University, including 2 males and 15 females with a mean age of 61.5 years old (48 to 75 years). The pre-operative diagnosis included osteoarthritis (14 patients, 19 knees) and rheumatoid arthritis (3 patients, 4 knees). The patients with valgus deformity were divided into group A and group B. The patients in group A were treated with the fixed-bearing prosthesis (9 patients, 12 knees), and the patients in group B were treated with the mobile-bearing prosthesis (8 patients, 11 knees). The Knee Society Score (KSS), Hosptial for Special Surgery (HSS), Western Ontario MacMaster (WOMAC), the range of motion (ROM) and femorotibial angle were collected at pre-operation and post-operation follow-up for statistical analysis.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 36 months (mean 25 months). The valgus deformity was corrected in all patients, and there were significant differences for all patients between pre-operation and post-operation at the latest follow-up with regard to the KSS knee score, function score, HSS score, WOMAC score, ROM and femorotibial angle (P<0.01). There were no significant differences in KSS knee score, function score, HSS score, WOMAC score, improvement in ROM and femorotibial angle between two groups at the latest follow-up. However there were significant differences in ROM (P<0.05) between fixed-bearing group (101.8±8.8)° and mobile-bearing group (108.4±7.2)° at the latest follow-up. No case with spin-out of mobile bearing was observed. There were no complications in any patient, such as infection, common peroneal nerve injury, dislocation and instability. The X-ary imaging showed no osteolysis or implant loosening.

CONCLUSIONThe early clinical outcomes of primary total knee arthroplasty by using mobile-bearing prosthesis and fixed-bearing prosthesis are satisfactory for the treatment of the valgus knee, and the short term clinical outcomes of mobile-bearing TKA and fixed-bearing TKA are similar.

Recently, the incidence of pulmonary cryptococcosis is gradually increasing in rheumatoid arthritis (RA) patients. Pulmonary rheumatoid nodules (PRN) are rare manifestations of RA. Eighteen months ago, a 65-year old woman was admitted to hospital due to multiple nodules (2.5x2.1x2 cm) with cavitations in the right lower lobe. She was diagnosed with RA three year ago. She had been taking methotrexate, leflunomide, and triamcinolone. A video-assisted thoracoscopic surgery biopsy was performed and PRN was diagnosed. However, a newly growing huge opacity with cavitation was detected in the same site. Pulmonary cryptococcal infection was diagnosed through a transthoracic computed tomograpy guided needle biopsy. Cryptococcus antigen was detected in serum but not in cerebrospinal fluid. The patient was treated with oral fluconazole which resulted clinical improvement and regression of the nodule on a series of radiography. Herein, we report the case of pulmonary cryptococcosis occurring in the same location as that of the PRN.

Glucocorticosteroid-induced osteoporosis is the most frequent of all secondary types of osteoporosis, and can increase the risk of vertebral compression fractures (VCFs). There are promising additions to current medical treatment for appropriately selected osteoporotic patients. Few studies have reported on the efficiency of percutaneous vertebroplasty (PVP) or kyphoplasty for whole thoracic and lumbar glucocorticosteroid-induced osteoporotic vertebral compression fractures. We report a case of a 67-year-old man with intractable pain caused by successional VCFs treated by PVP.

OBJECTIVETo introduce the procedure of the 1st ray stabilization combined with resection of the lesser metatarsal heads for patient with severe forefoot deformity caused by rheumatoid arthritis (RA) and evaluate the short to mid-term clinical results.

METHODSFrom Oct. 2006 to Aug. 2010,97 patients (129 feet) aged from 36 to 67 years (average 54), with forefoot deformity caused by rheumatoid arthritis were reviwed. There were 88 males and 9 females,65 single lateral involved and 32 bilateral involved, the average duration of disease was 17 years (6 to 32 years). The 1st ray instability and lesser metatarsophalangeal (MTP) joint stiff dislocation were found in all cases. The first ray stabilization combined with resection of the lesser metatarsal head procedure were performed for all cases. The radiographic Hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measurde and the JSSF (Japanese Society for Surgery of the Foot) score were evaluated before operation and every follow up.

RESULTSThe average followed-up was 37 months (6 to 52 months) for all patients except 5 (7 feet) and 1 died for acute cardiac infarction 1 year after operation. The average JSSF score improved from (33.2 +/- 8.2) points preoperative to (67.3 +/- 3.1) points at final followed-up (P < 0.01); the average HVA was corrected from (50.0 +/- 11.8) degrees preoperative to (21.2 +/- 3.2) degrees at final follow up (P < 0.01); the average IMA was corrected from (15.5 +/- 3.6) degrees preoperative to (9.7 +/- 6.6) degrees at final follow up (P < 0.01). MTP joint nonunion was found in 4 feet. A radiographic high density mass was found in the 1st cuneiform bone during 8 to 11 months followed-up in 3 feet; delayed wound healing was happened in 9 feet; MTP joint infection was happened in 2 feet; tarsometatarsal joint infection was happened in 1 foot; lesser MTP joints deformity recurrence were found in 16 feet.

CONCLUSIONThe characters of forefoot with RA in later stage are the 1st ray deformity and instability compound with the lesser toes deformity. The 1st ray stability procedure which include the 1st MTP arthrodesis and the Lapidus procedure can correct the 1st ray deformities and rebuilt its stability. The lesser toes metatarsal head resection is effective in correct their deformity. This combined procedure is reliable. It is suitable for patients with severe Hallux valgus, increased IMA, tarsometatarsal joint instability and the lesser MTP joint stiff dislocation.

BACKGROUNDSevere valgus deformity often has bone defect and laxity of the medial ligamentous, and total knee arthroplasty in severe valgus knee is, in most cases, more challenging for surgeons. The usefulness of a computer assisted navigation system in reestablishing the mechanical axis has been well established. Hence, the interest for surgeons is how the navigation system makes the procedure of total knee arthroplasty with severe valgus knee easier.

METHODSFrom June 2006 to March 2008 in Department of Joint Surgery, Shanghai Sixth People's Hospital, 6 patients (7 knees) with severe valgus knee underwent total knee arthroplasty using the Stryker Navigation system, which is an active wireless and imageless system. All the patients were followed up for 12 to 18 months after surgery. The X-ray radiographs for whole limbs were obtained on all patients to determine preoperative and postoperative alignments.

RESULTSA primary, posterior stabilized prosthesis was utilized in all cases. The average preoperative overall mechanical axis of the seven knees was 19.6° ± 4.6° of valgus (range 16° to 29°), and the average postoperative mechanical axis was 0.4° ± 0.7° (range 0.8° varus to 1.4° valgus).

CONCLUSIONSThe navigation system is a very effective and useful tool for accurate intraoperative restoration of alignment in the face of significant deformity with valgus knee. To prevent component malposition, we did not reduce the knee before solidification of bone cement but controlled alignment using the navigation system up to implantation of the final component.
