Early diagnosis of occult hip fractures MRI versus CT scan.

OBJECTIVE: We compared Computerised Tomography (CT) and Magnetic Resonance Imaging (MRI) in diagnosis of a painful hip in elderly patients after trauma. We report on accuracy, efficiency and benefits. DESIGN: We assessed 13 patients, average age 73 years, after fall with plain X-rays showing no evidence of fracture. There were two groups: Group A (six patients) underwent CT and MRI; Group B underwent MRI only. RESULTS: In Group A where all of the six patients underwent CT and MRI, four of the CT images resulted in misdiagnosis due to inaccuracy. In Group B where all the seven patients underwent only MRI, all the results were accurate and enabled a precise and fast diagnosis. CONCLUSIONS: MRI was found to be a more accurate modality than CT scan for obtaining early diagnosis of occult hip fractures. These results point out the advantage of immediate MRI imaging in patients with occult hip fracture enabling a more effective treatment, a shorter hospitalisation period entailing decreased medical costs.

Brucella prosthetic joint infection: a report of 3 cases and a review of the literature.

We report 3 cases of Brucella melitensis infection of prosthetic hips and knees, and we summarize data about 4 cases reported in the literature. Six of the 7 affected patients were men. The median duration from prosthesis implantation to the onset of symptoms was 38.7 months. Five patients had only local symptoms. Preoperative joint aspirates yielded negative culture results for 3 patients, and blood culture results were negative for 6 patients. Excisional arthroplasty was the initial intervention for 3 patients. Three others responded well to medical therapy alone. One patient had relapse while receiving tetracycline and underwent total hip replacement. All patients were treated with combined antibiotic therapy for 6 weeks to 19 months. All had favorable long-term responses. The 3 patients we treated underwent a 2-staged resection arthroplasty. Antibiotics alone can be used to treat Brucella prosthetic joint infection, but loosening of the joint and clinical or microbiological failure must be treated with a 2-staged excisional arthroplasty and 3 months of treatment with doxycycline and rifampicin.

Bell's palsy and herpes viruses: to (acyclo)vir or not to (acyclo)vir?

The majority of peripheral seventh cranial nerve palsy cases remain without an identified etiology and will eventually be diagnosed as idiopathic or Bell's palsy. Some features of this condition may be characteristic of a viral infection. Indeed, several herpes viruses have been implicated as potential causative pathogens. Besides varicella-zoster virus, shown to cause Bell's palsy under the Ramsay-Hunt syndrome, recent years have seen an increased interest and focus on the possible herpes simplex virus type 1 (HSV-1) etiology in idiopathic facial paralysis. We review the clinical, biological and virological basis for the potential herpetic cause of Bell's palsy and the rational for antiviral therapy in this condition.

Do axial dynamic fixators really produce axial dynamization?

The use of dynamic external fixators for the treatment of long bone fracture is widespread and well accepted. It is claimed that dynamization, i.e. small micromovements of compression/distraction at the fracture site, can be produced by allowing sliding of an inner rod within an outer housing. However, as the forces on the fixator are not direct but transferred from the bone via bone pins, there is a bending moment on the fixator. This produces "self-locking" and effectively prevents axial movements. We have studied the effect of this moment on the binding properties of the Orthofix system. The amount of movement at a simulated fracture site allowed before this locking occurs was measured and its implications discussed. It would appear that true axial dynamization does not take place using this system.

Floating metatarsal: concomitant Lisfranc fracture-dislocation and complex dislocation of the first metatarsophalangeal joint.

We describe a unique composite injury of the foot, with concomitant Lisfranc fracture-dislocation, and complex dislocation of the first metatarsophalangeal joint. When examining patients with Lisfranc joint injuries, one must keep in mind that the axial compression forces causing the injury may also damage the metatarsophalangeal joints, and direct attention to these structures. The reduction and stabilization of a "floating" first metatarsal should begin at the distal (metatarsophalangeal) end. The reduction of the distal dislocation will release tension on the plantar fascia, enabling the subsequent reduction of the proximal (Lisfranc) dislocation. A medial approach is convenient, affords easy access to the plantar and dorsal aspects of the joint, and repair of the medial joint structures when damaged. The use of screws for fixation of Lisfranc's fracture-dislocation, is well justified by the stability achieved.

[Surgical repair of fractures of the clavicle in the adult].

Clavicular fractures make up 45% of shoulder girdle fractures. The clavicle's susceptibility to injury is due to its subcutaneous position and its role as the bony connection between the thorax and the shoulder. In 95% of cases the mechanism of injury is a direct blow to the shoulder. These fractures are usually treated conservatively without surgery. But there are a few such fractures that require surgical repair in order to unite well. 9 patients were operated on for clavicular fractures during 1991-1995. The indications for surgical repair were lateral-third fracture, floating shoulder, neurovascular deficit or nonunion. The methods used were open reduction and fixation with either plate and screws, Kirchner wires, cerclage or a combination. All fractures united well, with no infections or new neurovascular deficits. Good range of shoulder motion and acceptable cosmetic results were achieved in all. 1 patient had functional limitation due to brachial neuritis caused by brachial damage at the time of injury. Indications for surgical repair and the methods used in these cases are similar to those described in the literature. The high rate of union and absence of complications support surgical repair for the few calvicular fractures that are not likely to unite properly.

Infections with Chryseomonas luteola (CDC group Ve-1) and flavimonas oryzihabitans (CDC group Ve-2).

We have described 15 cases of infection due to Chryseomonas luteola and Flavimonas oryzihabitans isolated between May 1990 and May 1994. These infections were often associated with the presence of a foreign body, especially central venous access and joint prosthesis. The high frequency of isolating C. luteola and F. oryzihabitans probably expresses the awareness of the clinicians and the laboratory to the importance of these bacteria, especially in patients with the presence of a foreign material.

Avascular necrosis of the femoral head following intertrochanteric fracture.

Two cases are reported of avascular necrosis of the femoral head occurring as a late complication of an intertrochanteric fracture. The cases are presented to emphasize the importance of including this condition in the differential diagnosis of any late clinical deterioration following such an injury.

Pneumococcal infection of a prosthetic hip joint.

A case of late haematogenous pneumococcal infection of a prosthetic hip joint is presented. In view of the relatively benign nature of pneumococcal arthritis, the patient was treated with parenteral antibiotics and surgical drainage without removal of the prosthesis. This was followed by complete resolution.

Ender nailing of acute humeral shaft fractures in multiple injuries.

From January 1987 to April 1993, 25 multiply injured patients were treated with closed intramedullary Ender nail fixation of the humeral shaft. Criteria for the procedure were humeral diaphyseal fractures with associated multiple injuries. Seventeen distal and mid-shaft fractures were treated via a modified anterograde approach in which the rotator cuff is not violated. Eight proximal third fractures were treated via the standard retrograde approach. Postoperative follow-up averaged 36 months. Full range of motion was attained 17 of the 25 patients. Of the eight remaining patients, three with a slightly limited range of motion achieved full range of motion following nail removal; three had preoperative radial nerve palsy which resolved within 1 year, and two patients required follow-on plating. In 92 per cent (23 of 25) there were no incidences of infection or non-union. Flexible nails avoid complications of reaming. The modified anterograde approach allows excellent shoulder motion since it does not violate the rotator cuff. Ender nails provide excellent fixation and clinical outcome in the multiply injured patient and are cost effective compared with interlocking nails.

Preadmission screening of patients scheduled for hip and knee replacement: impact on length of stay.

OBJECTIVE: An evaluation of the impact of a social work preadmission program on length of stay (LOS) of orthopedic patients undergoing elective total hip or total knee replacement surgeries (under diagnosis-related groups [DRGs]) at the Hadassah Ein-Kerem Hospital in Jerusalem is Israel. INTERVENTION: The social work interventions included preadmission psychosocial evaluation and preliminary discharge planning, coordination of nursing and physiotherapy evaluations, ensuring completion of all medical tests prior to admission, and additional psychosocial follow-up during hospitalization to carry out the original discharge plan or prepare alternatives. PATIENTS: The intervention patients were divided into two groups in order to see changes over time: May through December 1994 (n = 48), and January through December 1995 (n = 81). The comparison groups included patients operated on at the same hospital during 1993 (n = 51) and during January through April 1994 (n = 21) and at the Hadassah Mount Scopus Hospital during the same time periods. Patients in the comparison groups received usual social work intervention, as necessary, only after hospitalization. RESULTS: Mean LOS was reduced significantly in the intervention patient groups, as compared to the preintervention patient groups in the same hospital, from 14.2 days (standard deviation [SD], 4.7) in 1993 and 14.7 (SD, 5.1) in January through April 1994 to 10.9 (SD, 3.0) in May through December 1994 and to 9.1 (SD, 2.8) in 1995 (P < .01). Length of stay also was reduced in the comparison hospital, but by 1995 was longer than in the intervention patients. No differences in LOS by gender, age, or marital status were found. Length of stay was significantly longer for those undergoing total hip replacement as compared to those undergoing total knee replacement in all the groups. CONCLUSIONS: Preadmission screening and case management by a social worker can contribute to the efforts to decrease LOS of orthopedic patients by early multidisciplinary evaluations, discharge planning, and coordination of services.
