[Congenital radial head dislocation on both sides].

Both traumatic and congenital dislocation of the radial head are very rare in childhood. It can sometimes be difficult to tell them apart in practice. In this paper therefore, we present one case and discuss the various aspects of both conditions with reference to the available literature. Traumatic dislocation of the radial head is generally easily reduced without open surgery, and an open procedure is virtually never indicated in a patient who is still growing. In contrast, specific treatment of congenital radial head dislocation is not necessary because most patients are free of pain.

[Injuries of the midfoot in children].

Midfoot injuries of children are rare entities and often caused by high energy trauma mechanisms. Foot fractures in children may pose a diagnostic challenge but they usually have a good prognosis. In special cases computed tomography is necessary to find the right diagnosis in addition to plain X-rays. Based on two cases of midfoot injuries, a type II open Lisfranc fracture dislocation and a dislocation of a Chopart's joint, we describe the causes, diagnosis, and possibilities for treatment of juvenile midfoot injuries.

[Aplasia of the posterior tibial artery in a child with idiopathic clubfoot].

A case of a completely absent posterior tibial artery discovered during a procedure for congenital clubfoot correction in a 6 month old male infant is reported. Anomalies of the anterior tibial artery associated with the clubfoot-deformity are common, the absence of the posterior tibial artery is, however, very rare.

Time-dependent clinical and roentgenographical results of Coventry high tibial valgisation osteotomy.

We analyzed the time-dependent results after Coventry osteotomy in 118 patients (129 cases) with uni-compartmental osteoarthrosis of the knee. The median follow-up was 11.6 years (range 0.7-17 years). Data were noted according to the time since surgery. Group I (> 2 years) consisted of all 129 cases, group II (> 4 years) of 41 cases and group III (> 8 years) of 15 cases. The HSS knee score (max. 100 points) improved from 33.2 +/- 20.4 (range 17-60) to 68.3 +/- 25.3 (range 30-90) in group I, to 54.7 +/- 18.9 (range 29-90) in group II and to 43.7 +/- 20.9 (range 23-85) in group III. The improvement started 4.6 +/- 7.8 months (range 0-60 months) after the operation and persisted for 4 years +/- 37.4 months (range 0-125 months). The functional knee score (max. 100 points) changed from 61.7 +/- 14.1 (range 41-70) to 71.7 +/- 13.1 (range 53-87) in group I, to 70.0 +/- 11.8 (range 54-88) in group II and to 64.2 +/- 8.0 (range 42-90) in group III. The initial loss in knee flexion was 5.6 degrees (range 0 degree-20 degrees) and for extension 1.0 degree (range -5 degrees-25 degrees). Anteroposterior ligament stability (max. 10 points) decreased from 9.2 +/- 2.1 (range 2-10) to 5.6 +/- 1.7 (range 2-9) in group III. Lateral ligament stability (max. 15 points) was relatively constant, from 12.6 +/- 1.9 (range 4-15) to 9.7 +/- 1.9 (range 2-14). Complications included one tibia fracture, one infection, six peroneus pareses, four haematomas and one pseudarthrosis. The mechanical axis was corrected to an average knee valgu2 of 5.2 degrees +/- 7.4 degrees, which deteriorated over time. Radiographic evidence of arthrosis appeared independent of the operation.

Diagnosis and treatment of joint infections in elderly patients.

Clinical, laboratory and radiological data of 35 patients (> 60 years) with septic arthritis were retrospectively analyzed in 2 groups submitted to different treatment protocols based on the radiological stage of destruction. Group I: intraarticular gentamicin-PMMA beads (8 cases), group II: resection-arthroplasty with gentamicincement spacer (27 cases). The average diagnostic delay was 4.8 months. Diagnostic errors were: osteoarthrosis in 9 cases, periarthritis of the shoulder in 5, femoral head necrosis in 4 cases, sciatic pain in 3, osteoporosis in 1, and thrombosis in 1 case. The re-operation rate in group I was 1.4 (range 1-2 operations) and in group II 1.2 (range 0-3 operations). Fifteen patients were left with a resection-arthroplasty. The restriction of motion remained moderate in 6 and severe in 9 cases. Three patients had sepsis and died. The final results were poor after both treatment protocols. Early diagnosis seems to be the most determining factor concerning the final outcome of septic arthritis.

[Injuries of the bifurcate ligament].

The bifurcate ligament is a central stabilizer of the carpus. It is the one of the structures concerned in chain of fibular injuries in supination traumas. Damage to the bifurcate ligament is often missed in clinical and radiological diagnosis. Hints are given on the mechanism of injury, staging and graded treatment of this ligamentous injury.

[Soft tissue swelling in sports traumatology. Comparative study of the effectiveness of 2 ointments].

An open randomized study design was used to compare the soft-tissue swelling in patients with fibular capsule injuries under therapy with Chomelanum (preparation A), Lasonil (preparation B) and ointment base of Chomelanum (preparation C). 90 patients were selected for participation in the study, and the results of 85 patients were available for evaluation. Concerning the initial condition there was no significant difference between the three therapy groups of the study. Assessment criteria were the difference of circumference in plane of ankle joint (injured/uninjured side) and the difference of soft-tissue above lateral malleoulus in sonography. The study showed that preparation A had a significantly larger influence on soft tissue detumescence than preparation B- and B larger than C. In observation period all patients of group B and C still showed soft tissue swelling. Between third and fourth day of treatment half of patients in group A did not need any treatment because of complete detumescence. In all assessment criteria significant differences in favor of preparation A were observed.

[The risk of neurovascular damage in elbow joint arthroscopy. Which approach is better: anteromedial or anterolateral?].

In a cadaver dissection study the relation of the arthroscopic portals to the neurovascular structures was documented. In six cadaveric elbows the capsule was distended with 35-40cc fluid of 0.9% NaCl by using the direct lateral portal. An anterolateral and anteromedial approach to the elbow joint were established. The distance of the arthroscopic portals to the neurovascular bundles were measured at empty and filled joint after performing an anatomic dissection. The influence of flexion and extension of the joint as well as pronation and supination of the forearm on the distance of the arthroscopic sheath to the neural structures was documented. Lesions of the superficial cutaneous nerves were not seen. Using the anterolateral portal in the best position of the joint (90 degrees flexion and not distended joint at max. pronation of the forearm) we measured a proximity of 4.5 mm (range 2-10 mm) to the radial nerve. For the anteromedial approach the mean distance of the median nerve to the arthroscopic sheath was 15.5 mm (range 8-27 mm), when the optimal joint position was used (90 degrees flexed joint, distended, max. supination of the forearm).

Congenital ball-and-socket anomaly of the ankle.

We present the clinical and radiographic appearance of 11 patients with a ball-and-socket ankle joint with an average follow-up of 13.7 years. Ten patients demonstrated parallel symptoms of the femur-fibula-ulna syndrome (FFU) associated with a mean leg-length discrepancy of 4.3 cm (range, 2-20). In six patients, an annual follow-up of talar development was possible. Radiographically the patients showed an additional tarsal coalition at a mean age of 4.8 years (range, 3.2-5.9). This earlier fusion could be detected by an arthrographic examination. All patients had no clinical complaints except a slight reduction of hindfoot mobility. The ball-and-socket ankle joint is presumably not congenital itself but secondary to congenital conditions in the peritalar region.
