Despite some disadvantages associated with the anterolateral approach, the transgluteal and posterior approaches are often connected with a partial lesion of the gluteus medius and maximus muscles. In all approaches, clinical sequelae are not significant in primary THA.

In a clinical, retrospectively randomised study, we compared the results of the operation for a carpal tunnel syndrome when one side only or both sides were simultaneously assessed in one session. Of the 125 patients examined, 47.2% had both hands operated on in one session, 52.8% had only one hand operated on in one session or both hands in two sessions. We found the bilateral simultaneous operation to be associated with better results concerning earlier return to work, earlier relief of symptoms and better patient satisfaction than the operation on one side only. These are explained by the necessity of using both hands for daily activities and thus a guaranteed functional follow-up treatment after the bilateral operation. In conclusion, we propose operating on both hands simultaneously whenever possible, even if the opposite hand presents with only a slight CTS, which would otherwise not be considered for operation yet.

The efficacy of a total hip replacement with a hydroxyapatite-coated hip prosthesis was compared with that of an uncoated, cementless prosthesis of the same type. Preoperatively, there was no difference in the patient's diagnosis, hip score, age, and sex. All operations were performed by one surgeon in a standardized manner. The choice of the implant was randomized, and the follow-up period was equal for both types. The implant used was associated with a poor outcome due to a high incidence of early aseptic loosening. Probably because of a poor initial fixation, there was a significant difference in the clinical results after a short follow-up period when an additional HA layer was used. According to the patients' pain, migration of the implant, and presence of a progressive radiolucent line, use of the HA-coated prosthesis led to a significantly better result; however, we also found an increased rate of heterotopic bone formation in the HA-coated group. It was concluded that the HA coating improves the initial fixation of a hip prosthesis.

The case of a 55-year-old patient is described, presenting the clinical sign of a chronic infection of the tendon sheath. Upon incision a mass of brown synovial tumor was found. The X-ray showed a circumscript bone erosion. MRI demonstrated tumor involvement of all flexor tendons up to the forearm. Under radiation the tumor initially was diminished. Half a year later, pulmonary metastases were found. The destruction of the whole skeleton of the hand led to a forearm amputation. Later, a metastasis was found in the tongue. The patient died with the clinical signs of pulmonary insufficiency. Autopsy showed diffuse pulmonary metastases. This case is discussed together with other rare cases of malignant pigmented villonodular synovialitis arising from joints and tendon sheaths.

We describe a technique for arthroscopy of the wrist which is carried out without traction and with the arm lying horizontally on the operating table. The wrist is not immobilised, which makes it possible to assess the extent of instability after a ligamentous tear. In a prospective study of 30 patients we compared this technique with conventional wrist arthroscopy, performing the new method first followed by conventional arthroscopy. The advantages are that the horizontal position of the arm allows the surgeon to proceed directly from arthroscopic diagnosis to treatment, and that no change of position is required for fluoroscopy. In terms of diagnostic sensitivity, we found our technique matched that of conventional arthroscopy. We had no difficulty in carrying out minor surgical procedures such as debridement and suturing.
