[Ecthyma contagiosum (Orf) as an uncommon differential diagnosis of infections of the hand].

Orf of the hand is considered as an uncommon viral infection which is usually acquired through contact with infected sheep and goats. Indirect infections through contaminated knives or meat have been reported. Many authors feel that the disorder is more common than reported because the disease is often misdiagnosed and the course is usually self-limiting with spontaneous healing within several weeks. Diagnosis is mainly made by patient's history and clinical course. It is important to know the benign nature of human orf, since complications seem to be caused by overtreatment.

[Iatrogenic avulsion of the greater trochanter during prosthetic replacement of the hip].

An iatrogenic avulsion of the greater trochanter occurring during prosthetic hip replacement after a fracture of the neck of the femur is a rare complication. The need for maximum internal rotation of the limb during the operation imposes serious mechanical stress on the greater trochanter in patients who are often elderly and whose bones are osteoporotic. Two case reports illustrate that a conservative management--without internal fixation--combined with early mobilisation is successful. Our view is based on the current, international opinion that conservative management with early mobilisation is preferable for isolated traumatic avulsion of the greater trochanter, even if there is wide displacement.

Anterior interosseous nerve compression after supracondylar fracture of the humerus: a metaanalysis.

OBJECT: The authors conducted a metaanalysis of reports of anterior interosseous nerve syndrome, a rare nerve compression neuropathy that affects only the motor branch of the median nerve. This syndrome is characterized by paralysis of the flexor pollicis longus, the flexor digitorum profundus to the index finger, and the pronator quadratus, with weakness on flexion of the interphalangeal joint of the thumb and the distal interphalangeal joint of the index finger without sensory loss. METHODS: The authors reviewed reports of 34 cases of anterior interosseous nerve syndrome combined with supracondylar fractures of the humerus in children. They have added a new case identified in a 7-year-old boy in whom a diagnosis was made from the clinical findings and whose treatment and outcome are analyzed. The ages of patients reported in the literature ranged from 4 to 10 years. Ten patients (29%) were treated with closed reduction and application of a cast, whereas 25 patients (71%) were treated with open reduction and fixation of the fracture. CONCLUSIONS: All patients regained full flexion and strength after 4 to 17 weeks. The fractures that were surgically treated showed no entrapment of the anterior interosseous nerve.

[Mutilating complex trauma of the pelvis].

Traumatic hemipelvectomy is a rare, but devastating pelvic injury with few survivors reported in the literature. We report on a 19-year-old motorcyclist with a near-total hemipelvectomy. After a complicated course, the patient survived with good potential for a functional level of activity. We review the experience of other authors and give details on the management of one of the most challenging injuries confronting surgeons. Successful treatment requires extraordinary efforts and multidisciplinary team cooperation.

[Secondary reconstruction of flexor tendon function of the fingers].

Among the various procedures to restore flexor tendon function after failed or omitted primary suture flexor tendon grafting is the most frequently applied technique. It can be performed in a one-stage procedure using a palmaris- or plantaris graft in cases with less scarring or in a two-stage procedure for cases in unsuitable conditions. The main purpose for using silicone rods is to prepare an artificial tendon sheath to avoid adhesions of the tendon graft. The disadvantage of two operations seems to be justified by better results. We performed this technique in 168 zone-II-lesions. According to the Buck-Gramcko score we achieved excellent results in 30.9% and good results in 25.6%. In 76 fingers we applied the combination of the Paneva-Holevich technique of using a pedicled superficialis tendon with Hunters method without obtaining better results (22.4% and 32.9% respectively). The various techniques of grafting are described as well as indication and technique of tenodesis and alternatively staged procedure for isolated profunda lesions.

Clinical and biomechanical aspects of external fixation of the pelvis.

OBJECTIVE: The aim was to evaluate the mechanical stability of several traditional and modern external fixators in unstable pelvic ring disruption. DESIGN: In a laboratory study external and internal fixation techniques were tested in seven fresh and five embalmed human pelves with a disruption of the pubic symphysis and one sacroiliac joint (type C1.2 injury according to the Tile-AO classification). BACKGROUND: Stability provided by external fixation depends upon many factors, with the residual pelvic stability being the most important. METHODS: Simulating a single-leg stance, the load was applied quasi-statically to the acetabulum of the unstable hemipelvis. Device failure was defined as displacement >10 mm either at the symphysis pubis or the sacroiliac joint. RESULTS: The frame with the highest failure load (fresh versus embalmed specimens) was the Egbers configuration with the AO fixator (analysis of variance; P < 0.05). Failure was noted at 114.9 N versus 129.5 N. Augmentation of the Mono-Tube by additional internal posterior osteosynthesis gave the following results: sacral bars 325.4 N versus 217.8 N, plate fixation 294.3 N versus 215.8 N, lag screws 338.4 N versus 215.8 N. Failure loads of hybrid fixation of the Orthofix were as follows: sacral bars 257.9 N versus 213.9 N, plate fixation 333.5 N versus 245.3 N, lag screws 397.3 N versus 280.6 N. The differences between the two fixators were not statistically significant. CONCLUSIONS: No single external frame provided sufficient stability. The addition of a posterior internal fixation significantly increased failure loads and controlled the weight-bearing pelvic elements.

[Surgical treatment and results of healing of de Quervain stenosing tenovaginitis].

Within a period of 6 years we operated on 109 patients with De Quervain's disease. Of the patients 82% recovered completely, 18% had slight residual complaints, e.g. stress-dependent discomfort and irritations of the superficial radial nerve. The operative technique is presented in detail and the frequency of anatomical variations of the first extensor tendon compartment is emphasized.
