The open modified Bankart procedure: outcome at follow-up of 10 to 15 years.

We report the outcome of a modified Bankart procedure using suture anchors in 31 patients (31 shoulders) with a mean follow-up of 11 years (10 to 15). The mean age of the patients was 28 years (16 to 39). At follow-up, the mean Rowe score was 90 points (66 to 98) and the Constant score was 96 points (85 to 100). A total of 26 shoulders (84%) had a good or excellent result. The rate of recurrence varied between 6.7% and 9.7% and depended on how recurrence was defined. Two patients had a significant new injury at one and nine years, respectively after operation. The overall rate of instability (including subluxations) varied between 12.9% and 22.6%. All patients returned to work, with 29 (94%) resuming their pre-operative occupation and level of activity. Mild radiological osteoarthritis was seen in nine shoulders (29%) and severe osteoarthritis in one. We conclude that the open modified Bankart procedure is a reliable surgical technique with good long-term results.

Increased external tibial torsion and osteochondritis dissecans of the knee.

In the past, osteochondritis dissecans of the knee was associated with increased tibial exotorsion, established with a clinical measuring method. Now the gold standard for determining tibial torsion is computed tomography. The aim of the current study was to establish whether the abovementioned association could be confirmed in the current patients, measured with computed tomography. Confounding aberrations of femoral torsion were ruled out. Twenty-three patients with osteochondritis dissecans in 27 knees were treated between 1991 and 1999. Symptoms and treatment results were comparable with those reported in the literature. Femoral and tibial torsion were measured with a computed tomography scan. The average femoral antetorsion was comparable with that in the literature. The average tibial exotorsion was significantly higher than the control value. Exotorsion was increased more in patients with bilateral osteochondritis, and extremely high in patients with persisting complaints. Increased tibial exotorsion could play a role in development of osteochondritis dissecans of the knee. Extreme exotorsion might be prognostic for persistent complaints.

The prognosis following acute primary glenohumeral dislocation.

We have studied 105 patients with 107 acute, primary, dislocations of the glenohumeral joint seen between January 1, 1991 and July 1, 1994. The mean time of follow-up was 71 months (46 to 91). In 34% the injury occurred during a sports activity and in 28% at home. The bias toward sport was even greater in patients less than 40 years of age, and in men. In patients older than 40 years of age, and in women, the dislocation occurred more often at home. The overall probability of recurrence within four years was 26%. Age was the most significant prognostic factor in recurrence which took place in 64% of patients less than 20 years of age and in 6% of those older than 40 years. Statistically, there was no difference between the rates of recurrence in patients who were active in sport and those who were not. The mean Rowe score for the whole group was 87 (15 to 100). Associated fractures were found in 20 patients (19%) and nerve injuries in 22 (21%). None of those in whom a fracture of the greater tuberosity was seen subsequently suffered a recurrent dislocation. At follow-up we found that 36 patients (34%) had not returned to their former employment but in only 2% was this owing to the injured shoulder.

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.

Popliteal pseudoaneurysm after arthroscopic meniscectomy. A report of two cases.

Two cases of popliteal artery pseudoaneurysm after arthroscopic meniscectomy are reported. It is a very rare complication in arthroscopic knee surgery. Bypass grafting, using autogenic saphenous vein, was necessary after resection of the aneurysm in both cases.

[Pain in the forefoot: a support sole is no panacea]. / Pijn in de voorvoet: een steunzool is geen panacee.

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]. / Multidirectionele instabiliteit van de schouder; een nieuwe vorm van chronische schouderinstabiliteit.

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]. / Polsafwijkingen bij juveniele chronische artritis.

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.

[Hereditary onycho-osteodysplasia (HOOD)]. / De hereditaire onycho-osteo-dysplasie (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.

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.
