Free microneurovascular muscle transfer in limbs to provide motor power.

The experience gained in a series of 7 free microneurovascular muscle transfers to the limbs over a seven-year period has led us to conclude that: free gracilis microneurovascular flaps can be safely transferred and can aid restoration of movement following severe injuries of the limbs, including post-replantation cases; inclusion of a cutaneous island with the muscle is safe, improves cover, and simplifies closure following muscle transfer; tendon adhesions and joint stiffness are the greatest obstacles to transferred muscle function, and early passive extension is recommended; additional procedures are usually required after muscle transfer, to improve the level of function; and additional experimental work is required to determine methods of establishing the correct resting tension in transferred muscles.

Acute nerve grafting in traumatic injuries: two case studies.

Primary nerve grafting in traumatic injuries is rarely performed because of the uncertainty of the extent of injury, the limited availability of nerve grafts, and the damage to adjacent soft tissue. In this report the authors present two cases of acute nerve grafting after trauma-the first of the common peroneal nerve and the second of the ulnar nerve above the elbow-with sensory and motor recovery. Although compelling general arguments against primary posttraumatic nerve grafting exist, these cases illustrate that, in certain favorable and critical clinical situations, acute nerve grafting may be successful.

Medical and rehabilitation issues in classical ballet.

Classical ballet is a demanding professional occupation, with participants who are often underserved in terms of accurate diagnosis and appropriate comprehensive medical care. The view that follows is designed to be as global and insightful as published to date. Specific rehabilitation considerations, dance mechanics, idiosyncratic differential diagnosis, and personality and equipment issues are discussed, and a rational view of dogma is presented.

Multiple sequential posttraumatic pseudoaneurysms following high-energy injuries: case report and review of the literature.

A 15-year-old boy sustained severe multisystem injuries from a satchel charge while in his native village in southern Lebanon. After evacuation and resuscitation measures, he had successful intensive multidisciplinary surgical care. His long-bone fractures were stabilized by tubular external fixation systems, and his lacerated right tibialis anterior artery was grafted. Twenty days after injury, he developed a pseudoaneurysm of the left distal ulnar artery, which was surgically resected and the ulnar artery proximally ligated. Two weeks later, a pseudoaneurysm of the left peroneal artery, distal to the knee and coupled with an arteriovenous fistula, was diagnosed. This was treated by fluoroscopic controlled embolization with placement of stents. The patient recovered uneventfully. He was last seen two years after surgery, and no gross vascular compromise of any of his limbs was evident. This appears to be the only reported patient with late-developing multiple posttraumatic pseudoaneurysms after severe blast and shrapnel injuries. This development suggests that late sequelae of blast injuries may be topographically widespread and can evolve months after the injury. As such, these patients should be followed closely with a high degree of suspicion for the appearance of new signs or symptoms.

Power take-off injuries.

Power take-off injuries are uncommon, but serious and potentially fatal. Seven cases are reported demonstrating the violent trauma that can be incurred. The danger associated with use of machines with this and other power equipment is emphasized. Safety shields should be improved, and operators educated about the importance of retaining the shields and using machinery properly at all times.

Microvascular free groin flap for soft-tissue coverage of the extremities.

Six cases of microvascular free flap, composite tissue transfer are presented. The advantages of utilizing this modality of tissue coverage are that it is a direct one-stage procedure which, in experienced hands and using a two-team approach, can solve complex reconstructive problems with a minimal hospital stay and minimal morbidity.

Determinants of disability after lower extremity fracture.

BACKGROUND: Factors influencing the progression of physical impairment to patient-perceived disability are not well known. We sought to better understand this relationship in the setting of injury. METHODS: We followed a cohort of 302 patients with lower extremity fractures over a 1-year period. Physical impairment was assessed by range of motion, strength, and pain. Range of motion and strength were assessed together as a proportion of normal function of the extremity (impairment score). Pain was assessed using a Visual Analogue Scale (VAS) pain score. Disability was assessed using the Sickness Impact Profile (SIP), a widely used measure of patient-perceived limitations of everyday activities attributable to illness. The SIP was administered during hospitalization to assess preinjury baseline. Impairment assessment and readministration of the SIP were performed at 12 months after injury. RESULTS: Impairment in leg function (range of motion and strength) was highly correlated (p < 0.001) with overall SIP score at 12 months, but accounted for only 23% of the variance in overall SIP scores. Likewise, VAS pain score was highly correlated (p < 0.001) with overall SIP score at 12 months, but accounted for only 29% of the variance in overall SIP scores. In a multivariate linear regression analysis, variables that were independently associated with overall SIP score included impairment score, VAS pain score, preinjury SIP, poverty status, education status, social support, having hired a lawyer, and involvement with workers' compensation. These variables accounted for 52% of the variance in overall SIP scores at 12 months. CONCLUSION: The degree of physical impairment accounts for only a small amount of the variance in disability from lower extremity fracture. Identifiable patient characteristics including age, socioeconomic status, preinjury health, and social support together with impairment account for over half of the variance in long-term disability. Further research is needed to increase understanding of other factors that influence the progression of impairment to disability, especially those factors that may be amenable to intervention.

Limb reconstruction by free-tissue transfer combined with the Ilizarov method.

In four complex cases of extremity reconstruction, we have been able to overcome the problems of combined bone and soft-tissue loss and length discrepancy by a combination of free-tissue transfer and the Ilizarov method of slow distraction. It is our observation that gradual distraction of a free tissue is a safe and viable procedure; the free tissue tolerates the pins of the circular external fixator well, and there is an equal degree of distraction and regeneration of the transferred free tissue and the native recipient tissue without evidence of wound dehiscence. Corticotomy through free tissue and in close proximity to vascularized bone is safe, with the subsequent bone regeneration not unlike that of normal bone. Manipulation by slow distraction does not appear to compromise the vasculature of the recipient bed for later microsurgical procedures or endanger the axial flow pattern of the transferred free tissue.

The fate of lower extremities with failed free flaps.

This study reviews the outcome of patients with failed free flaps to lower extremities. The failure rate was 10 percent (41 of 413 flaps) over a 13-year period. Trauma patients (83 percent of all patients) had a failure rate of 11 percent, while nontrauma patients had a failure rate of 6.7 percent. The most common cause of failure was venous thrombosis (34 percent). Eight of 36 patients (22 percent) went on to amputation after the failed free flap; all were trauma patients. Patients with tibia-fibula fractures had a 35 percent amputation rate (6 of 17 patients) after a failed free flap. Seventy-eight percent of the patients (28 of 36) had salvage of their extremities by split-thickness skin graft, local flaps, or a second free flap. Long-term follow-up was available in 24 of 36 patients (67 percent), 20 of whom were salvaged without amputation. Of the patients whose limbs were salvaged, none had undergone an amputation at a mean follow-up of 6.2 years. All were ambulating, but 7 (35 percent) had intermittent wound breakdown. Despite an initial free-flap loss, the majority of extremities can be salvaged with subsequent procedures. However, on long-term follow-up, a large percentage of patients continue to have wound problems.

Conventional versus endoscopic free gracilis muscle harvest.

Compared with conventional techniques, the endoscopically assisted harvest of free tissue has advantages such as minimal interference with cosmesis and reduced donor-site morbidity. However, the procedure also requires training and has an extensive learning period. In this series of 22 patients, the initial gracilis muscle flaps were harvested using a conventional method; the subsequent flaps were harvested with the aid of endoscopic instrumentation. Endoscopically assisted gracilis muscle harvest in 16 patients was compared with open method harvest in six patients. The endoscopically assisted group had an average incision length of 6.5 cm; that of the conventional group was 15.5 cm. There was one reexploration in the endoscopically assisted group, but all flaps were transferred successfully. Using this minimally invasive technique of vascular and muscular dissection, assisted by endoscopic instruments designed for distal muscle dissection and transection, the gracilis muscles can be harvested within 40 minutes. We consider endoscopically assisted harvest of free gracilis muscle to be safe, relatively simple, and cost-effective.

Early decompression fasciotomy in the treatment of high-voltage electrical burns of the extremities.

Based on a knowledge of electropathophysiology, a recommended treatment has been proposed for the management of extensive high-voltage electrical burns. Early, aggressive, surgical intervention consisting of adequate decompression fasciotomy and wound debridement has been emphasized as the first line of treatment. Frequent redebridements under general anesthesia are important to the preservation of viable tissue. Early coverage procedures or attempts at primary closure following decompression are contraindicated in high-voltage injuries. This method of treatment in eight cases of high-voltage, electrical injury has preserved viable tissue, decreased the incidence of fatal sepsis and renal shutdown, decreased patient morbidity, and generally facilitated patient rehabilitation.

Bilateral first rib fractures associated with driver's air bag inflation: case report and implications for surgery.

A case of bilateral fractures of the first rib occurring in an otherwise fit road traffic accident victim is described. The only other injuries sustained were of the peripheral limbs. The driver's air bag was inflated during the crash, leading to speculation as to whether this may have contributed to the mechanism of injury. The patient was well oxygenated and cardiovascularly stable with no evidence of neurovascular damage to the thoracic aorta or its branches. Aortic arch aortography was not performed before internal fixation of the peripheral fractures was undertaken under general anaesthesia. A review of the indications for angiography in such patients follows. The policy that patients with fractures of the upper first ribs do not require angiography unless there is other evidence of neurovascular damage is supported.
