The floating shoulder. A multicentre study.

The aim of this retrospective study was to review a series of patients with ipsilateral fractures of the neck of the scapula and of the clavicle. Between 1991 and 1996 a total of 79 general and orthopaedic surgeons treated 46 patients with a floating shoulder in The Netherlands. The records and radiographs of these patients were studied. Of the 35 patients available for follow-up, 31 had initially been treated conservatively and four by operation; three underwent secondary reconstructive surgery. The mean Constant score for the 28 patients treated conservatively was 76 and for the seven treated operatively it was 71 at a mean follow-up of 35 months. In six of the 28 patients treated conservatively the glenoid was dislocated caudally at the end of treatment; they had a score of 42. In the 22 patients without this dislocation the score was 85. We conclude that this rare injury is not inherently unstable and, in the absence of caudal dislocation of the glenoid, conservative treatment gives a good functional outcome.

Isolated avulsion fracture of the lesser tuberosity of the humerus.

Six cases of isolated avulsions of the lesser tuberosity of the humerus were encountered within a short period of time. Although it seldom has been described in the literature, it might be a more common fracture than suspected. Physical examination revealed a painful shoulder with limited function in all six patients. In retrospect, all diagnoses could have been made on the primary plain roentgenograms. However, the fragment of the lesser tuberosity was easily misdiagnosed. An axillary view showed the fragment clearly in all cases. Computed tomography is useful for making an accurate diagnosis because it establishes the size and displacement of the fragment and determines additional injuries, such as a ruptured biceps tendon. Five patients with displacement of the lesser tuberosity were operated on after several weeks or months. The lesser tuberosity was reattached in all cases. After 6 months three patients had slight impairment of elevation and external rotation, and one of them suffered from pain during movements of the arm. The patient with no fracture displacement was treated conservatively with a good result. In conclusion, we recommended an axillary roentgenogram as part of the posttrauma radiologic series of the shoulder. A nondisplaced avulsion fracture of the lesser tuberosity of the humerus can be treated conservatively. We recommend reattachment of displaced fractures.

[Pain in the forefoot: a support sole is no panacea].

Three case histories of a painful forefoot due to an uncommon disease are given: Freiberg's disease, Morton's neuroma and metatarsal stress fracture. The differential diagnosis of metatarsalgia should include these diseases, especially if no static deformities are found.

[Multi-directional instability of the shoulder; e new form of chronic shoulder instability].

This article describes multidirectional shoulder instability. This lesion is not rare and is easily overlooked. MDI is often caused by repeated minor injuries in athletic patients. The basic lesion in MDI is an enlarged joint volume. The diagnosis is based on the clinical picture. The sulcus sign is pathognomonic. Conservative treatment is the treatment of first choice. If complaints persist after one year of conservative treatment, a capsular shift as described by Neer is recommended.

[Wrist disorders in juvenile chronic arthritis].

In Juvenile Chronic Arthritis the wrist often is involved. Synovitis of this joint gives rise to several types of disintegration, which can lead to serious deformities and loss of function. Therapeutical considerations should be based upon knowledge of these types of disintegration and the natural history.

Genetic counselling in hereditary osteo-onychodysplasia (HOOD, nail-patella syndrome) with nephropathy.

Hereditary osteo-onychodysplasia (HOOD, nail-patella syndrome) is an autosomal dominant condition characterised by nail dysplasia, patellar hypoplasia or aplasia, and nephropathy. The risk for HOOD patients to have a child with HOOD who will develop renal failure cannot easily be deduced from published pedigrees. We have studied a large family with 30 patients with HOOD and have analysed 34 kindreds with HOOD nephropathy from published reports, comprising 213 patients. For a patient with HOOD from a family in which HOOD nephropathy occurs, the risk of having a child with HOOD nephropathy is about 1:4; the risk of having a child in whom renal failure will develop is about 1:10.

Supracondylar fractures of the humerus in children; a long-term follow-up study.

The late anatomical and functional results of the conservative treatment of supracondylar humerus fractures were retrospectively studied in 87 children. The average follow-up was 14.5 years; 59 percent of the patients were treated with overhead traction and 32 per cent with a plaster of Paris. The average hospitalization time was 17 days. Rereduction was necessary in 23 patients; 16 of them were primarily treated with overhead traction. The overall results according to Høyer's criteria were good to excellent in 83 per cent of all cases. These results were comparable with other series with long-term follow-up. Cubitus varus was the most common late complication. Incomplete reduction seems to be the most important cause of this complication.

[Hereditary onycho-osteodysplasia (HOOD)].

Hereditary onycho-osteodysplasia (HOOD) is an autosomal dominant condition, characterized by dysplasia of the nails and joints and extra bone formation at the os ilium. Nephropathy occurs in some families with HOOD. We discuss a patient's history and the results of the study of her family. The incidence of all important features of this syndrome is given. Finally, some methods of treatment and genetic counseling are discussed.
