Interfascicular nerve grafting is a useful method to repair nerves with gaps. Good motor recovery can be obtained, and return of some degree of sensibility is possible. The procedure can be used to overcome small gaps that result from neglected sharp lacerations or after failure of primary repair, or large gaps that result from loss of nerve substance or traction lesions. Primary nerve repair should be done for acute lacerations. However, in old lacerations (more than three weeks old) and in nerve gaps of more than 2 cm in length, a functional recovery can still be expected after nerve grafting. The recovery of intrinsic function in median and ulnar nerve lesions above the elbow was poor. The intrinsic recovery in these patients will be reported when long-term follow-up results are available. Recovery of intrinsic function in median nerve grafts at the wrist level was much better than for lesions of the ulnar nerve at the same level. This may be related to the anatomy of the ulnar nerve in this area. By separating the dorsal cutaneous branch from the main trunk of the nerve, using it as a donor graft, better results are to be expected.

Fractures of the upper limb from the elbow downwards constitute the biggest group of bone injuries in both children and adults. The pattern of fractures sustained, however, varies between the two age groups as does the type of treatment required. It is not possible in an article of this type to consider all the different fractures which occur in the upper limb, and an attempt will be made to concentrate on those fractures where problems with diagnosis and treatment are prone to occur.
Although the operating microscope was introduced more than 50 years ago, its use was at first confined to otolaryngology and, later, to ophthalmology. More recently its use in the development of microvascular techniques has led to spectacular advances in the field of replantation and reconstructive surgery. The organization of microsurgical research at St Vincent's Hospital, Melbourne, is briefly described and clinical experience at this hospital over the past 10 years is reviewed. This includes 86 cases of digital replantation, with survival rates of 58% for complete and 82% for incomplete amputation, and 14 cases of major replantation (amputations proximal to the metacarpophalangeal joints) with a survival rate of 71%. In the second part of the lecture the use of microsurgery for composite tissue transfer and one-stage toe-to-hand transfer is discussed and experimental and clinical experience in microlymphatic surgery described.

A case of heterotopic replantation of the metacarpus is demonstrated. This procedure shows the successful primary reconstruction of a severely injured hand. The result seventeen months after the injury is shown. The patient is rehabilitated and is able to manage basic activities of daily living.
A rupture of the musculotendinous junction of the flexor digitorum superficialis to the index finger in a baseball pitcher is described. No underlying abnormality could be detected. Because of loss of strength and dexterity, repair of the rupture was accomplished with an improved result.
BACKGROUND: The aim of this study was to evaluate forearm and hand injuries in multitrauma patients and to compare this group of patients to the overall multitrauma population. PATIENTS AND METHODS: Out of a prospectively gathered polytrauma data base a retrospective analysis, including demographics, injury severity, injury pattern and treatment of forearm and hand injuries was performed. RESULTS: Out of 386 patients (G) that had been entered in our polytrauma data base, 26 had forearm and hand injuries (H). The mean age of group (H) was 36.4 years (G: 40.3 years, p = 0.220), the mean ISS of this population was 28,3 (G: 34.5, p = 0.003). Mostly fractures of the radius (50.0%), the metacarpus (53.8%) and the carpus (50.0%) were diagnosed. Surgical interventions of hand- and forearm injuries were done in 15 cases within 24 hours, 4 patients were treated after 24 hours. CONCLUSION: Multiple trauma patients with hand- and forearm injuries showed a statistically significant decreased injury severity and were younger compared to the overall multitrauma population.

A 53-year-old man sustained a 50 Hz, 60 kV electrical injury. The current flowed between his right hand and both feet. There was necrosis of the distal portion of the right forearm, and the fourth and fifth toes on the right foot. The skin on the amputated right upper extremity appeared normal except for an ulcer in the antecubital fossa and some blister scars. However, most of the muscles of the arm at the elbow were necrosed and partially replaced by fatty tissue or fibrosis. These necrotic areas corresponded to minimally increased signal intensities on T1-weighted MRI, and high signal intensities on T2-weighted images. MRI may be employed to predict amputation level after electrical injury.
Soft-tissue loss around the elbow can occur from trauma, burn injury, or tumor resection. Several factors, including the patient's age, sex, occupation, and general health status before injury or an operation, should be considered before choosing the method of wound closure. The surgical procedure must be tailored to the needs of the wound and the patient. This article discusses primary wound management and closure, flap coverage, and free-tissue transfer.
