Surgical Management of Comminuted, Displaced Greater Tuberosity Fractures: A New Technique of Subacromial Spacer on Top of Double-Row Suture Anchor Fixation.

Arthroscopic treatment of greater tuberosity (GT) fractures has been previously described. Arthroscopy allows identifying and addressing coexisting injuries, such as rotator cuff tears, labrum, or superior labrum anterior and posterior lesions, which are often present. Fracture comminution precludes the use of rigid fracture fixation with screws and arthroscopic rotator cuff repair is performed instead.

Superior-inferior stability of the shoulder: role of the coracohumeral ligament and the rotator interval capsule.

Objective: To study the superior-inferior stabilizing functions of the coracohumeral ligament (CHL) and the rotator interval capsule (RIC) with use of a material testing machine.

Material And Methods: The axial translations of the humerus with the superior-inferior translation force of 30 N applied were recorded under the following joint capsule conditions: (1) intact, (2) vented, (3) the CHL sectioned, and (4) the RIC incised in six cadaver shoulders. The order of sectioning was changed for conditions 3 and 4 in six other cadaver shoulders.

The early history of arthroplasty of the wrist. From amputation to total wrist implant.

During the past 3 decades implant arthroplasty of the destroyed wrist has become a reliable and satisfying procedure. However, the first total wrist replacement was performed in Berlin as early as 1890. This paper describes the history of resection and interposition arthroplasty of the wrist leading to the first total wrist implant arthroplasty performed by Themistocles Gluck.

Treatment of large bone defects with the Ilizarov technique.

Between 1985 and 1990 we treated 11 large segmental bone defects (average 6.7 cm) in ten patients with the Ilizarov technique. Open fractures, type III according to Gustilo, represented the largest group (8 of 11 cases).

Magnetic resonance imaging of nontraumatic shoulder instability in children.

Nontraumatic shoulder instability is infrequent in children. We examined prospectively with high-field magnetic resonance imaging (MRI) 11 patients with this disorder, including 2 with Holt-Oram syndrome and 11 healthy control subjects. The MR findings in the glenohumeral joint in normally growing children are presented.

[Hypocalcemia and myelofibrosis: an unrecognized association].

Observation of a case of myelofibrosis with myeloid metaplasia of liver and spleen associated with hypocalcemia led us to investigate whether this association was fortuitous. We retrospectively analyzed the data of 30 patients with myelofibrosis and identified 9 patients with hypocalcemia out of 22 in whom the plasma calcium level corrected for serum protein could be obtained, i.e.

Iridoids. A review.

Tre review presents a glossary of the iridoid glycosides, secoiridoids, bis-iridoids, and non-glycosidic iridoids. The following information is present for each compound, when available: structural formula, molecular formula, molecular weight, mp and [alpha]D values, uv, ir, 1H-nmr, 13C-nmr, and ms data, as well as mp and [alpha]D values for the correspondent acetate derivative. The natural source, the family and generic name, is given as well as the reference.
