OBJECTIVE: To compare effectiveness of multiple metatarsal osteotomy versus first metatarsophalangeal arthrodesis in treating severe metatarsal adductus hallux valgus deformity. METHODS: A retrospective analysis was conducted on the clinical data of 25 patients with severe metatarsal adductus hallux valgus deformity admitted between June 2010 and May 2014 who met the selective criteria. Among them, 15 patients underwent multiple metatarsal osteotomy (osteotomy group), while 10 patients underwent first metatarsophalangeal arthrodesis (fusion group). There was no significant difference between groups ( P>0.05) in gender, age, disease duration, affected side, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) score for pain, intermetatarsal angle (IMA), hallux valgus angle (HVA), or metatarsal adduction angle (MAA). The osteotomy group underwent fixation with screws and/or staples fixation, while the fusion group utilized anatomic fusion plates and trans-articular compression screws. The study compared the following outcome indicators between groups: operation time, pre- and post-operative differences (change values) in AOFAS scores, VAS scores, and radiographic parameters (HVA, MAA), osteotomy healing outcomes, and recurrence of hallux valgus deformity. RESULTS: Both surgical procedures were completed successfully. The operation time was significantly shorter in the fusion group than in the osteotomy group ( P<0.05). All patients were followed up 96-144 months (mean, 116 months). The follow-up time was (129.1±7.2) months in the osteotomy group and (104.4±8.0) months in the fusion group, with no significant difference between groups ( P>0.05). X-ray films revealed the radiographic union in two groups, and the fusion time was significantly shorter in the fusion group than in the osteotomy group ( P<0.05). At last follow-up, both groups demonstrated significant improvements in AOFAS and VAS scores compared to preoperative levels ( P<0.05). However, the differences in the change values of AOFAS and VAS scores between groups were not significant ( P>0.05). During follow-up, 3 cases (20%) of deformity recurrence occurred in the osteotomy group, while no recurrence was observed in the fusion group. There was no significant difference in the incidences of deformity recurrence between groups ( P>0.05). CONCLUSION For severe metatarsus adductus hallux valgus deformities, both multiple metatarsal osteotomy and first metatarsophalangeal arthrodesis can correct the deformity. The former preserves metatarsophalangeal joint mobility but demands high technical proficiency from the surgeon, involves relatively longer operation times, extended bone healing periods, and higher complication incidences. The latter procedure is relatively simpler, facilitates faster postoperative recovery, allows early weight-bearing, and yields more reliable outcomes, though it sacrifices first metatarsophalangeal joint mobility.

OBJECTIVE: To evaluate the mid-term efficacy of talonavicular joint fusion alone combined with navicular stress adjustment in Müller-Weiss disease with significant paradoxical flatfoot deformity. METHODS: Between January 2016 and March 2021, a total of 13 patients diagnosed with Müller-Weiss disease underwent simple talonavicular joint fusion combined with navicular stress adjustmentadjustment.Among them, 5 patients were male and 8 patients were female;age ranged from 42 to 67 years old. The duration of the disease ranged from 8 to 20 years. According to Maceira staging system, 5 patients were in stage III and 8 patients were in stage IV. The American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, visual analogue scale (VAS), and foot length were evaluated preoperatively and 10 months postoperatively. Additionally, the talonavicular coverage angle, the talus-first metatarsal angle, and the calcaneal inclination angle were assessed preoperatively and 6 months postoperatively. RESULTS: All 13 patients were followed up a period ranging from 24 to 40 months. All patients achieved clinical healing within a period of 3 to 6 months. However, one patient experienced a screw fracture. The VAS decreased from a range of 3 to 7 points preoperatively to a range of 0 to 2 points at the 10 months postoperative. The AOFAS midfoot score improved from a preoperative range of 12 to 66 points to a range of 72 to 100 points at the 10 months postoperative. Based on the AOFAS midfoot score evaluated at 10 months postoperatively, the outcomes were rated as excellent in 3 feet, good in 6 feet, and fair in 4 feet. The talo-navicular coverage angle, the preoperative talus-first metatarsal angle, calcaneal inclination angle were 14.3° to 33.4°, -4.6° to -19.6°, and 3.0°to 16.4° respectively. Six months postoperatively, these angles improved to 2.7°to 9.6°, -8.4°to 1.1°, and 18.8°to 24.9°respectively. Additionally, the foot length increased by 0 to 6 mm at 10 months post-surgery. CONCLUSION Simple talonavicular arthrodesis combined with scaphoid stress adjustment has satisfactory clinical efficacy in Müller-Weiss disease in terms of deformity, foot length, foot function and pain.

OBJECTIVE: To compare the effectiveness of supramalleolar osteotomy (SMOT) and ankle arthrodesis (AA) in the treatment of inverted ankle osteoarthritis (OA) in Takakura 3A stage with talus tilt. METHODS: The clinical data of 41 patients with inverted ankle OA in Takakura 3A stage with talus tilt admitted between January 2016 to January 2020 and met the selection criteria were retrospectively analyzed, and they were divided into SMOT group (21 cases) and AA group (20 cases) according to the surgical method. There was no significant difference in baseline data such as gender, age, affected side, cause of injury, and preoperative talar tilt angle (TT), American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) score, short-form 36 health survey scale (SF-36) score, and sagittal range of motion (ROM) between the two groups ( P>0.05). The operation time, intraoperative blood loss, partial weight-bearing time, and complications were recorded in the two groups. AOFAS ankle-hindfoot score, VAS score, SF-36 score, and sagittal ROM were used to evaluate the effectiveness. Bone healing was observed and the time of bony healing was recorded. In the SMOT group, the tibial lateral surface angle (TLS), TT, and the tibial articular surface angle (TAS) were measured on ankle joint weight-bearing anteroposterior and lateral X-ray films and compared with those before operation. And Takakura staging assessment was also performed. RESULTS: The operation time and intraoperative blood loss in AA group were significantly less than those in SMOT group ( P<0.05). Patients in both groups were followed up 24-36 months, with an average of 28.9 months. Incision infection occurred in 2 patients in SMOT group and 1 patient in AA group, respectively, and no vascular or nerve injury occurred in both groups. The partial weight-bearing time of SMOT group was significantly less than that of AA group ( P<0.05), but there was no significant difference in bony healing time between the two groups ( P>0.05). At last follow-up, the difference of VAS score and SF-36 score before and after operation of AA group were less than those of SMOT group, and the difference of sagittal ROM before and after operation in SMOT group was less than that of AA group, with significant differences ( P<0.05). The difference of AOFAS ankle-hindfoot score before and after operation in AA group was slightly greater than that in SMOT group, but the difference was not significant ( P>0.05). The above scores in both groups significantly improved when compared with those before operation ( P<0.05). Sagittal ROM in AA group was significantly less than that before operation ( P<0.05), while there was no significant difference in SMOT group ( P>0.05). In the SMOT group, 17 patients (81.0%) showed improvement in imaging staging, 2 patients (9.5%) showed no improvement in staging, and 2 patients (9.5%) showed stage aggravation. TLS, TAS, and TT significantly improved when compared with those before operation ( P<0.05). At last follow-up, 2 patients in SMOT group received AA due to pain and stage aggravation, and 1 patient with bone nonunion underwent bone graft. Subtalar joint fusion was performed in 1 case of subtalar arthritis in AA group. CONCLUSION For inverted ankle OA in Takakura 3A stage with talus tilt, both SMOT and AA can significantly releave pain, improve foot function and quality of life, but AA has more definite effectiveness and better patient satisfaction.

Ankle arthritis affects approximately 1% of the adult population worldwide and represents a serious global disease burden. However, compared with hip arthritis and knee arthritis, the clinical understanding and treatment of ankle arthritis are still in their infancy. For end-stage ankle arthritis, ankle arthrodesis was considered as the "gold standard" in the past. However, ankle arthrodesis will result in loss of joint mobility, altered gait, limited daily activities, and accelerated degeneration of adjacent joints. Therefore, how to preserve the range of motion of the ankle joint while relieving pain is the key to the treatment of ankle arthritis. Currently, the surgical treatment of ankle arthritis includes arthroscopic debridement, periarticular osteotomies, osteochondral transplantation, ankle distraction arthroplasty, ankle arthrodesis, and total ankle arthroplasty. The choice of treatment should be individualized and based on various factors such as the patient's symptoms, signs, imaging performance, complaints, and financial situation. However, there are no guidelines that give clear treatment recommendations. Therefore, it is necessary to conduct extensive and in-depth discussions on the diagnosis and treatment of ankle arthritis.

OBJECTIVETo evaluate the functional outcomes of modified limited "L" incision beside the Achilles tendon with distraction bone block arthrodesis in treatment of subtalar osteoarthritis.

METHODSFrom March 2009 to September 2012, a total of 22 cases of old calcaneus fractures with subtalar osteoarthritis were treated with modified limited "L" incision and distraction bone block arthrodesis including 13 males and 9 females with a mean age of 35.3 years old (ranged 22 to 49). The mean time from calcaneal fracture was 21 months (ranged 11 to 32). According to the Stephens-Sanders classification, 16 cases were type II and 6 were type III. The modified-AOFAS ankle-hindfoot score was used for functional outcomes evaluation.

RESULTSThere was one incision necrosis and no infection, implant failure, bone-graft absorbed or talus necrosis was note at the follow-up time. A total of 21 cases were followed up for a mean time of 29 months (ranged from 18 to 46 months). All of the cases reached a bony union within 4 months postoperation. The mean modified-AOFAS ankle-hindfoot score was 82.6 points (ranged from 66 to 92 points),reached a significantly improvement in comparing with the mean preoperative score (50.8 points,ranged from 32 to 65 points, P < 0.01).

CONCLUSIONThe modified limited"L" incision beside the Achilles tendon with distraction bone block arthrodesis is an acceptable and alternative treatment method for subtalar osteoarthritis. This method is easy to use and with less complication. It can correct the main pathological changes and reach good functional outcomes.

We report the surgical technique used to perform posterior-stabilized total knee arthroplasty (TKA) in two patients with a well positioned and functional hip arthrodesis. Intraoperatively, the operating table was placed in an increased Trendelenburg position. Episodically, we flexed the foot of the table by 90degrees to allow maximal knee flexion to facilitate exposure and bone cuts. We opted to resect the patella and tibia first to enable exposure, given the stiffness of the arthritic knee. One patient's medical condition prohibited complex conversion total hip arthroplasty (THA) prior to the TKA. The other patient's scarred soft tissues around the hip, due to chronic infection and multiple operations, made THA risky. The final outcome provided satisfactory results at a minimum of 2 years postoperatively. TKA can be successfully performed with adjustments of table position and modification of the sequence of surgical steps in patients with ipsilateral hip fusion.

BACKGROUND: To evaluate the efficacy of intramedullary K-wire fixation and interosseous wiring in the arthrodesis of the distal interphalangeal (DIP) joint with description of surgical procedure. METHODS: We retrospectively analyzed 9 cases (7 women and 2 men) of DIP joint arthrodesis. The average age of patients was 44.2 years (range, 21 to 71 years) and the mean follow-up period was 19.6 months. Joint union was evaluated on the follow-up radiographs together with postoperative complications. RESULTS: All cases achieved radiologic union of the arthrodesis site. There was no surgical complication except for one case of skin irritation by the interosseous wire knot which was removed during the follow-up period. CONCLUSIONS: Intramedullary K-wire fixation and interosseous wiring could be an alternative procedure of arthrodesis in the DIP joint.

PURPOSE: This study was designed to evaluate the mid-term results and efficacy of subtalar distraction double bone-block arthrodesis for calcaneal malunion. MATERIALS AND METHODS: From January 2004 to June 2007, we operated on 6 patients (10 cases). There were 5 males (9 cases) and 1 female (1 case), four of which presented with bilateral calcaneal malunion. Seven cases were operated on initially. The period between initial injury and arthrodesis was 23 months, and the average follow up period was 58 months. In operation, we applied an extensile lateral approach and arthrodesis was performed through a tricortical double bone-block and cannulated screws. The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale was used for clinical evaluation. In radiologic analysis, plain X-ray and CT were examined to assess union and various parameters. RESULTS: The mean age of the patients was 41 years. All cases achieved radiologic union at the final follow-up. The mean AOFAS Ankle-Hindfoot scale (maximum of 94 points) increased from 43.3 points preoperatively to 85.4 points at the final follow-up. The radiologic analysis of the pre- and postoperative standing lateral radiographs showed improvements of 5.6 mm in talo-calcaneal height, 1.8degrees in talocalcaneal angle, 5.1degrees in talar declination angle and 5.3degrees in talo-first metatarsal angle. CONCLUSION: Subtalar distraction two bone-block arthrodesis provides overall good results not only in the short term but also the mid-term with significant improvement in clinical and radiologic outcomes. This procedure warrants consideration for managing calcaneal malunion with loss of height and subtalar arthritis.

OBJECTIVETo investigate the clinical outcome of modified Blair ankle fusion for ankle arthritis.

METHODSBetween November 2009 and June 2012, 28 patients with ankle arthritis were treated, among whom 11 had obvious foot varus deformity, and 17 were almost normal in appearance. There were 13 males and 15 females with an average age of 49.4 years (range, 23-67 years). The main symptoms included swelling, pain, and a limited range of motion of the ankles. The ankle joints functions were assessed by American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and visual analog scale (VAS) preoperatively and at 1 year follow-up.

RESULTSTwenty-eight patients were followed up for 19.8 months on average (range, 1-2 years). Superficial wound infection occurred in 3 cases, and was cured after debridement; the other incisions healed by first intention without complications. All ankles were fused at 1 year follow-up after operation. The symptom was relieved completely in all patients at last follow-up without complication of implant failure, or nonunion. The postoperative AOFAS ankle and hindfoot score was 83.13±3.76, showing significant difference when compared with the preoperative score (45.38±3.21, P<0.01). VAS was significantly decreased from 8.01±0.63 to 2.31±1.05 at 1 year follow-up (P<0.05).

CONCLUSIONModified Blair ankle fusion has the advantages of high feasiblity, less cost and rigid fixation. It shows high reliability in pain relief and may obtain a good clinical effectiveness.

OBJECTIVETo observe the outcome of treatment for serious old intra-articular calcaneal fracture by reconstruction of calcaneal thalamus and subtalar arthrodesis and to summarize the operative indications and its attention points.

METHODSFrom March 2006 to July 2011,26 patients with Sanders type III old intra-articular calcaneal fracture were treated including 15 males and 11 females with an average age of 34 years old ranging from 27 to 45 years old. The clinical courses ranged from 7 to 24 months with an average of 18 months. Before the operation,X-ray and CT showed that Gissane angle increased while Böhler angle decreased,and calcaneus broadened,bulging on both sides. After the operations,all patients tested by imaging examination, and the width of calcaneus, the height of calcaneal thalamus, the Böhler angle and Gissane angle were measured to compare with the preoperative data. Besides, for identification of improvement of the operation,the functions of patient's feet after the operation were graded according to AOFAS Ankle-Hindfoot Scale to compare with preoperative data.

RESULTSAmong them, 24 patients were followed-up from 5 to 26 months with an average of 19 months. X-rays confirmed that all cases healed successfully. There were no serious infection, and only one skin necrosis case. Sural neurocutaneous island flap was used to repair the skin with success. According to AOFAS Ankle-Hindfoot Scale, the total score increased from preoperative (41.00 +/- 8.22) to postoperative (79.04 +/- 7.46). There were 3 cases of excellent result, 15 cases of good result,and 6 cases of fair result. Postoperative width of calcaneus, the height of thalamus, Böhler angle and Gissane angle were better than that of preoperative data, and had statistical significance between two groups.

CONCLUSIONSubtalar arthrodesis with the reconstruction of calcaneal thalamus is an effective way to treat old intra-articular calcaneal fractures. It can correct the calcaneal deformity, restore the shape of foot and improve the function of hind foot.
