An assessment of trauma management in the Wellington region.

Trauma is one of the leading causes of death and disability. In an effort to reduce mortality and morbidity from trauma changes to the methods of delivery of trauma care have been proposed, with the establishment of trauma units in Europe and the United States. There is little data to support the efficacy of these changes. This study reports the results of management of 311 multiple trauma victims from the time of the accident until the final outcome was known. The results cast doubt on some of the claims made which have been used to justify the establishment of trauma units.

Fractures of the lateral process of the talus.

This study is a retrospective review of nine patients who sustained isolated fractures of the lateral process of the talus. The majority were caused by inversion or a combination of inversion and dorsiflexion of the foot. Following a review of the literature and anatomical dissections the authors recommend a classification based on anterior-posterior tomography of the talus, into intra- and extra-articular fractures.

Isoelastic uncemented hip arthroplasty--early experience.

With the increasing failure rae with time of cemented total hip arthroplasty there is a growing interest in uncemented total joint replacement. This review of 88 Isoelastic total hip arthroplasties, and 28 Isoelastic hemiarthroplasties suggests that this implant gives results comparable with cemented total hip arthroplasty at a similar time. The Isoelastic hip replacement system uses uncemented components that have been designed to closely approximate the biomechanical properties of the bone into which they are implanted. The surgical technique is demanding, and orthopaedic surgeons who anticipate using uncemented implants should receive thorough training before embarking on an implantation.

Effects of nutrient intake, surgery, sepsis, and long term administration of steroids on muscle function.

The stimulated contraction-relaxation characteristics of the adductor pollicis muscle were used to assess nutritional state in patients and healthy controls. In both groups insufficient nutrition resulted in abnormal muscle function. The ratio of force of contraction at 10 Hz to that at 20 Hz yielded the best combination of sensitivity (87%) and specificity (82%). Sepsis resulted in abnormal muscle function, but the changes were easily distinguishable from those in subjects taking an inadequate diet. Long term administration of steroids, trauma, and surgery had no effect on muscle function. A prospective study of 11 malnourished patients with abnormal muscle function showed that all variables of muscle function returned to normal values with total parenteral nutrition. This reversal correlated significantly with the duration of parenteral nutrition and occurred before any change in anthropometric variables or plasma albumin concentration. Muscle function studies are sensitive and specific indicators of malnutrition; results depend on energy intake but are not influenced by administration of steroids, trauma, or surgery.

Spondylo-epiphyseal dysplasia tarda. The X-linked variety in three brothers.

Three brothers with the X-linked variety of spondylo-epiphyseal dysplasia tarda are presented. Their clinical courses differed: one was relatively free of symptoms, the second had slowly progressive osteoarthritis of the hip, and the third had an acute, disabling arthritis necessitating total hip arthroplasty. The clinical features of this disorder are reviewed.

Nonunion of the radial head.

A case of posterior fracture-dislocation of the elbow with a comminuted radial head fracture which subsequently went on to nonunion is reported. Radiographs at followup revealed a pseudoarthrosis of the radial neck, with at least part of the normal pronation and supination occurring through the pseudoarthrosis site.

Fractures of the proximal humerus in adults.

Fractures of the proximal humerus are a common upper-extremity injury, particularly in the elderly. The literature suggests that the results of treatment of displaced fractures are generally unsatisfactory. Since Neer's articles in 1970 we found little reported in the literature on these fractures. We conclude from our review of 90 fractures that the results of treatment of displaced fractures continue to be unsatisfactory, and we believe that displaced proximal humeral fractures, along with femoral neck fractures, should be classified as unsolved fractures.

Galeazzi fractures.

A series of 27 Galeazzi fractures treated by open reduction and rigid internal fixation have been reviewed. The average followup was 32 months. Twenty-five patients obtained a satisfactory result. One patient developed a pseudarthrosis after a fracture through a screw hole, an unsatisfactory result. A second patient sustained a severe open fracture with considerable soft-tissue damage and this result also rated as unsatisfactory. There were no infections. The authors believe that open reduction and rigid internal fixation of the radial fracture is the treatment of choice for this injury.

Chevron osteotomy for the treatment of hallux valgus.

Seventy-six chevron osteotomies with follow-up periods ranging from six months to eight years were reviewed. The majority of patients had pain over the bunion prior to operation, and 27 also presented with second metatarsalgia. After surgery there was a marked decrease of pain in the first metatarsophalangeal joint, and in 18 feet the second metatarsalgia was either eliminated or markedly decreased. Most patients were pleased with the appearance of the feet after surgery, but almost one-third of the women complained of difficulty in wearing high heels. The surgical technique is straightforward, but careful attention to detail is necessary to obtain a consistent and satisfactory result.

Pes cavovarus following ankle fracture. A case report.

Pes cavovarus as a late sequela of tibial shaft fractures is well recognized. A similar deformity following an ankle fracture is rare. The patient in the present report had a cavovarus deformity following a trimalleolar fracture. A deep posterior compartment syndrome may follow an ankle fracture and should be considered in any patient with unrelenting pain.

Supracondylar fractures of the humerus in adults.

Supracondylar fractures of the adult humerus are uncommon and present a difficult management problem. In this series of 50 patients better results were obtained by conservative rather than surgical management. In this series poor results were all related to inability to obtain rigid fixation at operation and resultant prolonged immobilization. Initial radiographic assessment is difficult and the shape of the distal humerus makes internal fixation a technical challenge. Except for simple fractures, conservative management is the recommended treatment.
