Neurologic injury from axillary block anesthesia.

Three cases of severe permanent neurologic injury following axillary block anesthesia from a single hand surgery practice are presented, along with the results of a survey regarding complications of axillary block anesthesia sent to the membership of the American Society for Surgery of the Hand. This survey resulted in 800 replies. Of respondents, 171 (21%) had seen a major neurologic complication at some time in their practice. Minor, transient complications were reported by 521 respondents (65%). Only 232 respondents (29%) reported no major or minor neurologic complications in their practice. These cases and the results of this survey suggest that serious permanent neurologic injury following axillary block anesthesia, although rare, may be more frequent than previously believed. Transient neurologic problems following axillary block are common but generally do not lead to long-term problems. Permanent neurologic injury following axillary block anesthesia is a devastating complication and should be carefully considered when determining the preferred anesthesia for an individual patient.

Treatment of difficult PIP joint fractures with a mini-external fixation device.

Closed intra-articular proximal interphalangeal (PIP) joint fractures--often with accompanying joint subluxation--constitute a difficult treatment problem. This article presents an alternative method consisting of closed treatment of complex PIP joint fractures with a mini-external fixator. The method utilizes the traction principle without necessitating a complex outrigger system. Immobilization is reduced to 3 weeks and monitored with a mini-fluoro unit. The three cases presented had 1- to 2-year follow-up and excellent clinical results despite suboptimal roentgenographic appearance.

Mycobacterium avium complex tenosynovitis of the index finger.

A rare case of tenosynovitis of the right index finger caused by Mycobacterium avium complex is reported. A high index of suspicion resulted in early culture-based diagnosis. Surgical synovectomy combined with a prolonged course of antituberculous medications resulted in normal hand function.

Warm ischemic damage to the epiphyseal growth plate: a rabbit model.

Warm ischemic growth plate damage was produced in the hindlimbs of 33 New Zealand white rabbits, who were 7 weeks old, by isolating the knee joint on a popliteal vascular pedicle. Zero, 3, 7, and 12 hours of warm ischemia were produced by pedicle occlusion. The 0- and 3-hour ischemic groups showed mild growth disturbances related to the surgical model and were not statistically different at 90 days postoperatively. The 7- and 12-hour ischemia groups showed severe growth disturbances and were statistically different from the 0- and 3-hour groups at all periods measured (p less than 0.05). Large central growth plate lesions were apparent by histologic examination. Twelve hours of ischemia produced a histologic picture identical to growth plate infarction. Increased warm ischemic time correlated with more severe growth retardation and evidence of increased damage to the central area of the growth plate histologically.

Group B beta-hemolytic streptococcal arthritis and osteomyelitis of the wrist.

A case of septic arthritis and osteomyelitis of the wrist with group B beta-hemolytic streptococci in an adult is reported. Neonatal septic arthritis and osteomyelitis caused by this organism have been previously reported. While rare in the adult, sporadic cases of septic arthritis and osteomyelitis have been seen. The elderly patient with diabetes seems to be a high-risk patient. Underlying chronic arthritis may confuse or delay the diagnosis.

Surgical treatment of adenocarcinoma of the stomach in a community hospital.

The experience with the surgical treatment of adenocarcinoma of the stomach in a community hospital from 1970 to 1979 is presented. The single most important prognostic factor for survival is the extent of disease at the time of operation. Positive regional nodes or distant metastases are associated with a dismal survival regardless of treatment. Other variables such as histologic findings, tumor morphologic features or location did not affect survival in our series. Although fewer and somewhat less radical operations were performed by a large number of community surgeons, the results were comparable to those reported elsewhere. The results depended most strongly on the extent of disease at operation. Aside from a fortunate and unexplained decrease in the incidence of adenocarcinoma of the stomach in this country, the best hope for decreased mortality in the future lies with earlier detection at a surgically curable stage.

A new microvascular clamp for the production of experimental ischemia.

A new microvascular clamp was developed from inexpensive and readily available materials. This clamp, when properly applied, can provide many hours of vessel occlusion with minimal damage to the vessel intima. This clamp has important applications in producing prolonged experimental ischemia without significant vessel damage and thrombosis. This clamp produced less vessel damage when compared with a standard microvascular clamp for prolonged periods of clamping.
