Introduction

End-stage ankle osteoarthritis is a debilitating condition that results in functional limitations and a poor quality of life. Ankle arthrodesis (AAD) and total ankle replacement (TAR) are the major surgical treatment options for ankle arthritis. The purpose of the present study was to compare preoperative and postoperative participation in sports and recreational activities, assesses levels of habitual physical activity, functional outcome and satisfaction of patients who underwent eighter AAD or TAR.

The aim of this study is to present guidelines for treatment of acquired adult flat foot (AAFF) and review the results of a series of patients consecutively treated. 180 patients (215 feet), mean age 54? 12 years affected by AAFF were evaluated clinically, radiographically and by MRI to chose the adequate surgical strategy. Tibialis posterior dysfunctions grade 1 were treated by tenolysis and tendon repair (48 cases), grade 2 by removal of degenerated tissue and tendon augmentation (41 cases), grade 3 by flexor digitorum longus tendon transfer (23 cases); in these cases subtalar pronation without arthritis was corrected by addictional procedures consisting of either calcaneal osteotomy (66 cases), subtalar athroereisis (25 cases) or Evans procedure (21 cases) in case of severe midfoot abduction. Subtalar arthrodesis (82 cases) or triple arthrodesis (21 cases) were performed in case of subtalar arthritis isolated or associated with midtarsal arthritis respectively. Postoperatively plastercast without weight-bearing for 4 weeks followed by walking boot for 4 weeks was advised. All patients were followed up to 5 years. Before surgery the mean AOFAS score was 48+\−11, while it was 89+\−10 at follow-up (p< 0.005). Mean heel valgus deviation at rest was 15°+\−5° preoperatively and 8°+\−4° at follow-up (p< 0.005). Mean angulation of Meary’s line at talonavicular joint level was 165°+\−12° preoperatively and 175°+\6 at follow-up. Surgical strategy in AAFF should include adequate treatment of tibialis posterior disfunction and osteotomies for correction of the skeletal deformities if joints are arthritis free; arthrodesis should be considered in case of severe joint degeneration

INTRODUCTION: Post-traumatic arthritis of the ankle in the young active patient represents a reconstructive challenge. Fresh total shell osteochondral allografts are an increasingly popular option in the reconstruction of various amounts of cartilage defects, although concerns for bipolar allografting are reported. The purpose of this study is to describe the preliminary results of a series of 18 bipolar shell ankle allografts performed by using a specifically designed instrumentation.

METHODS: 18 patients, 13 males and 5 females (mean age 31±10 years) affected by post traumatic arthritis of the unilateral ankle joint grade III received bipolar shell allograft of the ankle. The mean follow-up was 12 months (range 24–8). The ideal patient to allograft match was permitted through CT scan and x-rays. Two steps surgery, one for allograft preparing and one for the recipient site, were performed by using specifically designed jigs. Patients evaluation was carried out clinically by AOFAS and radiographically by X-Rays, CT scans, MRI.

RESULTS: No intraoperative, complications occurred. All the patients demonstrated good consolidation rates of the allograft at X-Rays, CT scan and MRI controls performed at 4, 6, 8, and 12 months. At 8 months follow-up, all the patients were allowed complete weight bearing. Normal ROM of the ankle and regular gait with no pain and no need of support was resumed in 13 patients. In 2 patients a fracture of the fibula was reported. In one case, cause of the fracture was patient non compliance to the weight-bearing restriction. In the other case the fracture occurred distal to the osteotomy site, possibly due to a trauma. Both the cases required revision of the graft which appeared damaged in the lateral site. In the first case an ankle arthrodesis was performed. A bioptic harvest of the transplanted cartilage in 5 patients at 1 year follow up demonstrated chondrocytes vitality > 90%.

DISCUSSION: Accurate preoperative planning, sizing, and the use of specifically designed jigs makes viable and reproducible the bipolar shell allograft in the ankle joint in selected cases. Although preliminary results are encouraging, longer follow-up is required in order to confirm longer term cartilage viability and the validity of the technique.

OBJECTIVE OF THE STUDY: Metatarsal osteotomies are common procedures for correction of hallux valgus. The aim of this study is to compare linear distal metatarsal osteotomy (LDMO) with SCARF osteotomy a clinical prospective randomised study.

METHODS: Forty patients affected by bilateral hallux valgus similar in both sides regarding clinical and radiographic assessment were included. X-rays, AOFAS, Maryland Foot Score (MFS) were considered before surgery up to 4 years follow-up. All patients were operated bilaterally, and received SCARF osteotomy in one side, and in the other LDMO performed through a 1 cm skin incision under the direct view control. Duration of surgery was recorded. Postoperative care was similar in both groups and consisted of gauze bondage and weight bearing with talus shoes for 4 weeks.

RESULTS: No statistical differences were observed in preoperative HVA, IMA, PASA in both groups. Average surgical time was 17 minutes in SCARF and 3 minutes in LDMO (p< 0.0005). No complications were observed in the series, with no wound dehiscence. All osteotomies healed. At 4 year follow up, no statistical differences were observed in HVA, IMA, PASA comparing SCARF with LDMO. Average AOFAS score was 87±12 in SCARF and 89±10 in LDMO (p=0.07), and MFS was 86±7 in SCARF and 90±3 in SERI (p=0.08).

CONCLUSION: Both SCARF and LDMO techniques resulted effective in the correction of hallux valgus, however SERI, a minimally invasive technique, performed with a shorter skin incision, more rapid surgical time, fixed with a less expensive device (one kirshner wire), resulted in a better clinical outcome.

INTRODUCTION: Distal metatarsal osteotomies have been described for surgical treatment of hallux valgus with good results. The aim of this study is to review the results of our first 1000 consecutive hallux valgus cases treated by minimally invasive distal metatarsal osteotomy, SERI (Simple Effective Rapid Inexpensive).

MATERIAL AND METHODS: 1000 feet in 641 patients (359 bilateral), aged between 20 and 65 years (mean 49) affected by hallux valgus without arthritis were studied. Inclusion criteria were deformity less than 40° and intermetatarsal angle up to 18°. A 1-cm medial incision at the metatarsal neck, and a complete osteotomy were performed using an oscillating saw. With the naked eye all characteristics of the deformity were corrected by displacement of the metatarsal head (HVA, IMA, PASA, dorsal or plantar displacement). The osteotomy was stabilized by a 2-mm Kirschner wire. Immediate weight bearing was allowed with gauze bandage and talus shoes for 4 weeks. All patients were checked at an average follow-up of 37 months.

RESULTS: All osteotomies healed, delayed consolidation was observed in 25 feet. Slight stiffness was observed in 31 feet. Mean AOFAS score was 48+15 pre-op and 89+13 at follow up. The pre-op HVA was 32+8, while at follow-up it was 18+8 (p< 0.005), pre-op IMA was 14+3, while at follow-up it was 6+4 (p< 0.005), the pre-op PASA was 21+9, while at follow-up was 9+8(p< 0.005).

DISCUSSION AND CONCLUSION: SERI osteotomy was simple, effective, rapid and inexpensive in correcting hallux valgus deformity. Clinical and radiographical findings showed an adequate correction of the deformity.

INTRODUCTION: Displaced comminuted intra-articular calcaneal fractures (DCCF) need anatomic reduction to avoid painful subtalar joint, deformities, tendon or nerve impingment. Open reduction and internal fixation has been extensively reported, but all series reported considerable rate of skin complications, infections and need of additional plastic procedure. The aim of this study is to review a series of DCCF operated by minimally invasive technique.

MATERIAL AND METHODS: 66 DCCF type Sanders II-III were selected in 63 patients aged 18–57 years. X-ray and CT scan were performed. Surgery consisted of percutaneous traction-reduction of the calcaneal body by bone forceps and fixation by K-wires under image intensifier. Then, a lateral 3 cm skin incision was performed to reduce subtalar joint and to fix it by 1 or 2 screws. In case of involvement of the calcano-cuboid joint, the incision was distally extended and a 4-hole plate was applied. K-wires were removed 5 weeks after surgery and weight bearing was permitted 12–16 weeks after surgery. Patients were evaluated clinically by AOFAS score and radiographically at 4 years follow-up (3–7).

RESULTS: No skin complications or infections were encountered in the series. All fractures healed. Mean postoperative Bohler angle was 29±5°. AOFAS score was 89±11. 31 cases were excellent, 22 good, 9 fair and 4 poor. 25 cases presented radiographic signs of subtalar joint arthritis, painful only in 4.

DISCUSSION AND CONCLUSION: Minimally invasive surgical treatment resulted adequate for treating DCCF, in fact if soft tissues are preserved by surgical trauma, dangerous complications like infections and skin problems can be avoided.

Introduction: The main goal of surgical correction of hallux valgus is the morphological and functional rebalance of the first ray and correcting all the characteristics of the deformity. Historically, distal metatarsal osteotomies and SCARF have been indicated in cases of mild or moderate deformity with inter-metatarsal angles up to 20° and are procedures widely used for correction of hallux valgus. The aim of this study is to compare a distal metatarsal osteotomy recently described (SERI) with SCARF osteotomy in a clinical prospective randomised study.

Methods: 20 patients with bilateral hallux valgus similar on both sides regarding clinical and radiographic assessment were included. Clinical evaluation using American Orthopaedic Foot and Ankle Score (AOFAS) and radiographic assessment were considered before surgery up to 2 years follow-up. All patients were operated bilaterally in the same surgical sitting, and received at random SCARF osteotomy on one side, and on the other a SERI osteotomy performed through a 1 cm skin incision under tdirect view control and fixed with one Kirschner wire. Duration of surgery was recorded. Postoperative care was similar in both groups and consisted of gauze bandage and weight bearing with talus shoes for 30 days.

Results: No statistical differences were observed in preoperative HVA, IMA, DMAA in both groups. Average surgical time was 17 minutes in SCARF and 3 minutes in SERI (p< 0.0005). No complications were observed in the series, with no wound dehiscence. All osteotomies healed uneventfully. At 2 year follow up, no statistical differences were observed in HVA, IMA, DMAA comparing SCARF with SERI. Average AOFAS score was 87±12 in SCARF and 89±10 in SERI (p=0.07).

Conclusions: Both SCARF and SERI techniques proved effective in the correction of hallux valgus, however SERI, performed with a shorter skin incision, in less surgical time, fixed with a cheaper device (one Kirschner wire), resulted in a better clinical outcome.
