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.

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.

Introduction: In situ subtalar arthrodesis cannot restore anatomical shape of the hindfoot in severe flat foot deformities. Purpose of this paper is to evaluate the result of 250 feet consecutively operated by subtalar arthrodesis with distraction and insertion of a mini structural bone block (SAMBB).

Material and Methods: 178 patients (250 feet), mean age 55+/−11 years affected by acquired adult flat foot with subtalar arthritis were evaluated clinically and radiographically and selected to receive SAMBB.

Arthrodesis was performed through a 2.5 cm incision, with partial cartilage removal and insertion of a structural corticocancellous block (2 × 1cm), harvested from the proximal ipsilateral tibia, vertically positioned into the sinus tarsi. Associate procedures were Achilles tendon lengthening (124), SERI procedure (61), hind-foot deformity correction (32). Postoperatively plaster-cast without weight-bearing for 4 weeks followed by walking boot was advised. All patients were reviewed at a minimum follow-up of 5 years.

Results: Before surgery the mean AOFAS score was 42+/−15, while it was 90+/−8 at follow-up (p< 0.005). Mean heel valgus deviation at rest was 15°+/−8° preoperatively and 6°+/−5° at follow-up (p< 0.005). Mean angulation of Meary’s line at talonavicular joint level was 160°+/−11° preoperatively and 174°+/−8 at follow-up. No complications were found. No or minimal arthritis progression was observed in the ipsilateral foot joints at follow up.

Conclusions: SAMBB resulted in an adequate correction of the deformity, with restoration of the anatomical shape of the hind foot and correction of the relationship with the midtarsal joint with no need of hardware. Consequent reduced arthritis progression and excellent clinical result were obtained.

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.

Introduction: Facioscapulohumeral muscular dystrophy (FSHD) is the third most common hereditary disease of the muscle after Duchenne and myotonic dystrophy. FSHD consists in an atrophic myopathy with predominant involvement of the face, upper arms, and shoulder muscles. FSHD compromises the muscles of the scapu-lothoracic joint, and usually spares muscles of the scapu-lohumeral joint. Consequently, when the patient tries to abduct or foreword flex the shoulder, the contraction of the relatively preserved scapulo-humeral muscles produces an abnormal rotation of the scapula, that is not hold to the chest wall because of the insufficiency of the scapulo-thoracic muscles, resulting in a winged scapula and in a limited arm motion. The aim of this study is to describe an original scapulopexy and report the long term results obtained in 9 patients affected by FSHD.

Material and methods: Nine patients (4 male and 5 female) affected by winged scapula in FSHD were observed and selected. Average age at surgery was 25 years (range 13–39). Surgery consisted in scapulopexy of both sides in the same surgical time. Through a skin incision on its medial border the scapula was exposed and positioned over the chest. The 5th to the 8th ribs were exposed in the part below the scapula. The position of the scapula over the chest was fixed by 4 doubled metal wires to the 5th, 6th, 7th and 8th rib. Each wire was passed anteriorly to the rib, and into a hole performed 1.5 cm from the medial border of the scapula. By tightening the wires, the scapula was fixed firmly over the chest. A figure of eight dressing that holds the shoulders back was applied immediately after surgery and maintained for six weeks.

Results: The average surgical time was 65 minute for each single procedure. One patient experienced an unilateral pneumothorax the day after operation, which resolved spontaneously in 48 hours. Average follow up was 11 years (range 3–15). All patients experienced a complete resolution of the winged scapula and an improvement of range of motion of the shoulder compared to the pre operative conditions. Average pre-operative abduction was 68 and post-operative was 85. Average pre-operative flexion was 78 and post-operative 112.

Discussion: This technique is easy and quick to perform, does not require grafts, reduces post surgical complications such as pneumothorax or haemothorax, and ensures good results even at considerable follow-up.

Introduction: Neck hyperextension (NH) is defined as a progressive increase of lordosis associated with a limitation in flexion of the cervical spine, which ultimately results in an inability to approximate the chin to the sternum. NH may occur in relation to several myopathies. It is characterized by a general weakness and contractures of the axial muscles which produces a progressive increase of lordosis associated with a limitation in flexion of the cervical spine, that forces the patient to assume awkward compensatory postures to maintain balance and level vision. This study reports on operative complications, the degree of correction, the achievement of a solid arthrodesis, the maintenance of the correction and the clinical assessment of 7 patients.

Material and methods: Seven patients affected by various myophaties and NH were included. The mean age was 16.5 years (10–28 years). All underwent surgery, in which the paravertebral muscles were detached from the spinous processes and then transversally sectioned in order to bilaterally expose the laminas of vertebrae C2 to C7. The space between C1–C2 appeared mobile, while the spinous processes from C2 to C7 were close together and thus allowed only a very limited motion in between them. Ligamenti interspinosus and nuchae were detached and the facet joints from C2 to C7 were enlarged by capsulotomy. With a spreader rongeur, the interspinous spaces at each level were gently opened. Cortical cancellous autologue graft were shaped into wedges. After careful opening of each interspinous space, the bone wedges were driven between the spinous processes to maintain the achieved correction. The average follow-up time was 10.4 years (2.4–16.5 years).

Results: No major surgical complications occurred. At follow-up, the average angle between C2–C7 in neutral position had decreased (p = 0.016) from 50.7 (40–70) to 21.4 (2–50). The range of motion in the C1–C2 joint remained unaffected, while it decreased in C2–C7 (p = 0.016) from 33.5 (15–64) to 1.8 (0–8). In all cases, a solid arthrodesis was achieved.

Discussion and conclusion: The follow-up showed significant clinical improvement of posture in all patients. Our study has shown surgical treatment of NH to be an effective method within the whole series of seven patients, achieving both good immediate and good long-term results.
