Objective

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.

Material and methods

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.

Material and Methods

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.

INTRODUCTION: Diaphyseal aseptic nonunions are challenging complications in forearm fractures, as length imbalance of radius and ulna impairs severely its function. The aim of this study is to report the results of a series of patients operated on by an original technique.

MATERIAL AND METHODS: 60 patients aged 17–72 years (mean 35) were treated between 1980 and 2000. Ten patients presented radius nonunion, 37 ulna non-union, and 13 nonunion of both bones. Nonunions occurred after conservative treatment in 8 cases, after one surgical procedure of plating or nailing in 47 cases and after 2 or more surgical procedures in 5 cases. Surgical treatment occurred at mean 36 months after the fracture and consisted of freshening the bone and applying a plate and an opposite cortical bone allograft; in 17 cases omologous intercalary bone graft was applied to restore length, axial and rotational alignment. Postoperative treatment consisted of functional bracing associated with intensive rehabilitation of the elbow and wrist beyond clinical and radiographic union. Average follow up was 15±7 years.

RESULTS:. One implant failed due to infection, requiring additional surgery. Mean elbow ROM was 122°±18. Compared with the contralateral arm, mean loss of wrist ROM was 20°±17. Mean loss of forearm rotation was 25°±15. Average healing time was 14±4 weeks X-ray analysis showed bone healing and good osteointegration of the graft in all cases.

DISCUSSION AND CONCLUSION: Combining a plate and an opposite massive cortical bone graft resulted to be a very effective technique for surgical treatment of forearm nonunions.
