Acute poliomyelitis is a very rare disease in western countries, however the remnant of the pathology can be find among the adult patients. In poliomyelitis, sensation is normal and patients may suffer from painful etiologies. Total knee arthroplasty (TKA) with non-hinged or semi hinged prosthesis systems may be a good options to relief the pain in poliomyelitic patients, however the knee remains unstable. Using the hinged system implant may be the good option to resolve the late. Although the main concern in case of hinged implant usage is the mechanical stress which is directly transferred to the bone surface in contact with the implant. This may leads to implant mobilization and consequently failure. From 2004 to 2014, 14 TKA were performed in poliomyelitic patients with secondary knee pain. All patients were presented with extensor compartment hyposthenia and reduced antigravity function. In all patients a third generation rotating hinged knees (RHK) implant system (Zimmer, Warsaw, IN, USA) was applied. Bilateral TKA was performed in only one case. The mean age at the time of surgery was 56 years (ranged 48–77). Mean follow-up was 60 months (24–112). Results Due to post-operative infection, one patient underwent knee arthrodesis and excluded from the study. In one case, patellar fracture occurred 3 month following the surgery and treated non-surgically. Pain relief was observed in all patients following the surgery without any major complication. Mean objective score according to knee society knee scoring system was improved from 28 (16–51) preoperatively to 79 (72–88) postoperatively. Mean functional score was improved from 24 (5–35) preoperatively to 66 (50–70) postoperatively. At last follow up the mean range of motion was 90° (75°−100°). Following radiographic control at last follow-up all implants was stable without any sign of failure such as mobilization, radiolucency line or osteolysis.Introduction
Methods and Materials
High grade hallux rigidus is a forefoot deformity characterized by a limitation of dorsiflexion of the first toe associated with pain, and severe damage of the first metatarsophalangeal joint. Most authors recommended resection arthroplasty or arthrodesis of the first metatarsophalangeal joint. The aim of this study was to present the results of our series of 42 consecutive cases of severe hallux rigidus treated by resection of the first metatarsal head and implant of a poly D-L lactic (PDLLA) bioreabsorbable spacer to promote the interposition of fibrous tissue to preserve the range of motion of the joint. Forty-two feet in 27 patients affected by high grade hallux rigidus were included in the study. Surgical treatment consisted of resection of the first metatarsal head and positioning of a poly D-L lactic acid (PDLLA) bioreabsorbable implant. Post-operative care consisted in gauze bandage of the forefoot, and immediate weight-bearing with talus shoes for 3 weeks. All patients were clinically and radiographically evaluated preoperatively and checked at a mean 6 (5–7) year follow-up.Objective

Combined metatarso-phalangeal and inter-phalangeal deformity represents about 1% of hallux valgus deformity, and its treatment remains a debated topic, because a single osteotomy does not entirely correct the deformity and double osteotomies are needed. The aim of this study is to review the results of 50 consecutive combined metatarso-phalangeal and inter-phalangeal hallux valgus treated by Akin proximal phalangeal osteotomy and SERI minimally invasive distal metatarsal osteotomy. Fifty feet in 27 patients, aged between 18 and 75 years (mean 42 years) affected by symptomatic hallux valgus without arthritis were included. Two 1-cm medial incisions were performed at the metatarsal neck and at proximal phalanx. Then SERI osteotomy was performed to correct metatarso-phalangeal deformity and Akin osteotomy was performed to correct interphalangeal deformity. Both osteotomies were fixed with a single K-wire. A gauze bandage of the forefoot was applied and immediate weight-bearing on hindfoot was allowed. K-wire was removed after 4 weeks. All patients were checked at a mean 4 year follow-up.Objective
