Flail limb

Abstract: OBJECTIVE: Previously, we reported bypass coaptation of the C3 and C4 anterior rami to the upper trunk of the brachial plexus for restoration of the muscles denervated as a result of C5 and C6 nerve root avulsion. This procedure is thought to be superior to the transfer of individual peripheral nerve fibers to the brachial plexus branches. Therefore, the benefits of the bypass coaptation procedures in the treatment of various root avulsions are presented. METHODS: Twenty-six patients were selected as suitable candidates for bypass coaptation procedures. They were divided into 3 groups: 1) Erb-Duchenne palsy due to C5 and C6 root avulsion, 2) Klumpke palsy due to C8 andT1 root avulsion, and 3) the flail arm (or flail upper limb) due to C5 through T1 root avulsion. The surgical techniques are described in detail. RESULTS: The coaptation procedures for the first group resulted in excellent recovery of all the denervated muscles. The patients in the second group showed reinnervation of the finger muscles and finger sensory distributions in infants within the first year after surgery. The flail arm group regained satisfactory proximal muscle function but only mild distal muscle function. One exception was a child who showed significant recovery in proximal and distal motor and sensory function. CONCLUSION: We recommend the bypass coaptation as a useful procedure for the following categories: Erb-Duchenne palsy due to C5 and C6 root avulsion in all ages, Klumpke palsy due to the C8 and T1 avulsion, and the flail arm due to C5 through T1 avulsion in young children. However, bypass procedures for the flail limb in adults require additional innovative methods to facilitate the growth rate of regenerating nerves.

Abstract: The treatment of a severe traction injury resulting in complete, posttraumatic brachial plexus palsy remains a daunting challenge to the upper extremity surgeon. Operative intervention must address painful glenohumeral instability while optimizing functional rehabilitation. Glenohumeral arthrodesis has been shown to reliably alleviate pain from shoulder instability and place the extremity in a functional position for activities of daily living. An above the elbow amputation has also been advocated to remove the flail insensate extremity and create a stable stump for prosthetic training and rehabilitation. We describe the technique of a combined glenohumeral arthrodesis and above elbow amputation to address the flail insensate limb following a severe posttraumatic brachial plexus injury. In our clinical experience, the combination of procedures results in an improved pain level, enhances shoulder stability, encourages functional rehabilitation via prosthetic fitting, and is associated with high patient satisfaction.

Abstract: Background and aim of the work: The term “floating shoulder” was used in a previous paper to describe lesions of at least two components of the SSSC (superior shoulder suspensory complex), a bony-ligamentous structure of the shoulder girdle. Following this article other types of floating shoulder were described, including scapulothoracic dissociation (STD), a rare lesion with potentially devastating consequences, with detachment of the scapular body from the thoracic wall, with following lateralization of the scapula, fracture of the clavicle or injury of the adiacent sterno-clavear or acromion-clavicular joints. Prognosis and outcome are also negatively influenced by secondary vascular and neurologic injuries. Methods: We review the literature on this lesion and we describe two patients with STD, their treatment and outcome. Results: Reviewing the literature and analysing our cases, we point out that the STD is often associated with serious general lesions and is indicative of an high-energy trauma. The consequences can be disabling for the upper limb (20% amputation, 50% flail limb) or for the general status of the patient (10% mortality). Conclusions: STD must be timely recognized and subsequently properly treated, to avoid the associated general and local injuries (vascular) and subsequently the musculoskeletal lesions.

Abstract: A case of extraskeletal chondrosarcoma of the left brachial plexus is described with emphasis on the diagnostic and therapeutic difficulties of this site. With combination therapy the patient survived 6 years. Recurrent disease in the plexus region and adjacent spinal cord resulted in a painful, flail limb. © 1992 Wiley-Liss, Inc.
