[Primitive renal synovial sarcoma: a cystic tumor in young patients].

Introduction: The study of the clinical, histological and immunohistochemical aspects of three kidney tumors corresponding to synovial sarcomas operated on in our center over three years.

Patients And Method: Three patients aged between 27 and 33 had an enlarged nephrectomy for kidney tumors corresponding to a histological examination of a synovial sarcoma. The tumors were symptomatic in 100% of cases with back pain and spontaneous rupture.

[Value of percutaneous biopsy for solid renal tumours less than 4 cm in diameter based on a series of 53 cases].

Objective: To evaluate the reliability and clinical value of percutaneous biopsy in the diagnosis of small solid renal tumours (less or equal to 4 cm).

Material: Fifty-three patients underwent biopsy for solid renal tumour less than 4 cm in diameter (mean age: 61 years). The mean diameter was 2.

A simple suture shuttle in rotator cuff repairs: a technical note.

In rotator cuff repairs, it is often necessary to pass 2 tails of 2 sutures through 1 transosseous hole to maximize the number of sutures per hole. We report on a simple technique with a double-loop suture thread that allows the passing of more than 1 suture limb through the same hole. This simple device, the simple suture shuttle, used in cuff repairs in combination with the modified Mason-Allen suture technique, significantly reduces the difficulty of passing more than 1 suture tail through a single bone tunnel.

Humeral retrotorsion and glenohumeral relationship in the normal shoulder and in recurrent anterior dislocation (scapulometry).

The authors' roentgenographic technique provides precise assessment of the glenohumeral relationship on the basis of two-plane examination. A group of 50 normal male subjects serve as the basis for determining normal values for the following angles or lines: projected and corrected cephalodiaphyseal angle, projected and corrected humeral retrotorsion, glenoid inclination, angle of attack, glenoid retroversion, dimension of glenoid, width of humeral head, and contact index. Two groups of patients suffering from recurrent anterior dislocation (RAD) are compared with the normal group.
