One bone forearm with vascularized fibular graft. Clinical experience and literature review.

One-Bone-Forearm (OBF) is a procedure in which the proximal stump of the ulna is fixed to the distal stump of the radius. Historically, the indications for OBF have been represented by forearm instability due to trauma, infection, tumor resection, and congenital deformities with severe radius and ulna bone loss. When major bone loss prevents direct fixation between ulna and radius a Vascularized Fibular Bone Graft (VFBG) may allow forearm bone reconstruction and fixation. In this study we report our clinical experience in 4 cases of OBF with VFBG performed in 3 patients. Compared to standard OBF technique with direct osteodesis, OBF with VFBG showed similar clinical results and high rate of healing even in case of bone infection. Moreover, composite osteocutaneous VFBG might concurrently allow to treat local soft tissue defects.

Treatment of flexor tendon reconstruction failures: multicentric experience with Brunelli active tendon implant.

INTRODUCTION: Secondary repair of flexor tendon injuries remain a challenging procedure for hand surgeons. Usually, secondary reconstruction should be performed by staged approach. When the tendon and pulley integrity are intact, tenolysis may be the first surgical option. One-/two-stage tendon grafts are suggested when the integrity of flexor tendon is compromised. Active tendon implants (Brunelli prostheses) may represent an efficient option in patients with a poor prognosis, as well as whenever classical techniques fail. Due to lack of literature about this second-line treatment, the authors present the experience of two different orthopedic departments with the permanent active tendon implant. MATERIALS AND METHOD: Nineteen consecutive patients with failed previous flexor tendons repairs were treated with active tendon implants between 2000 and 2011. The functional outcome of the patients was examined with a mean follow-up of 5.6 years, using Strickland assessment and QuickDASH. RESULTS: In 16 cases, the tendon implants were well tolerated and patients resulted satisfied with a QuickDASH score less than 33. Strickland score was fair to excellent in 10 patients. We registered adhesion complications in 3 cases. CONCLUSION: We can conclude that these prostheses represent an alternative to biological reconstructions and a potentially permanent procedure in complicated flexor tendon injuries. LEVEL OF EVIDENCE: Multicentric case series, Level IV.

Reconstruction of traumatic losses of substance at the elbow.

Traumatic lesions at the elbow involving great loss of substance are uncommon, but represent a significant problem when such cases are referred to a trauma department. Most of these injuries may cause severe final functional impairment, thereby jeopardising future activities, particularly in cases where treatment was delayed or inappropriate. The timing and method of treatment are critical. The trauma may involve soft tissues only, or bone and joint, or several structures at the same time, which results in combined complex tissue defects. Each type of tissue loss should be managed by choosing the most suitable technique from the armamentarium of reconstructive surgery, taking into account different priorities and the optimum timing (immediate or delayed, one- or two-stages). The authors describe a spectrum of indications and techniques that can be useful tools in managing these injuries.
