We have examined 167 patients who had a hemiarthroplasty for three- and four-part fractures and fracture-dislocations of the head of the humerus in a multicentre study involving 12 Austrian hospitals. All patients were followed for more than a year. Anatomical healing of the tuberosity significantly influenced the outcome as measured by the Constant score and subjective patient satisfaction. With regard to pain, the outcome was generally satisfactory but only 41.9% of patients were able to flex the shoulder above 90 degrees. The age of the patient and the type of prosthesis significantly influenced the healing of the tuberosity, but bone grafting did not. Achievement of healing of the tuberosity was inferior in institutions at which less than 15 hemiarthroplasties had been performed (Mann-Witney U test, p = 0.0001).
The surgical treatment of three- and four-part fractures of the proximal humerus in osteoporotic bone is difficult and there is no consensus as to which technique leads to the best outcome in elderly patients. Between 1998 and 2004 we treated 76 patients aged over 70 years with three- or four-part fractures by percutaneous reduction and internal fixation using the Humerusblock. A displacement of the tuberosity of > 5 mm and an angulation of > 30 degrees of the head fragment were the indications for surgery. Of the patients 50 (51 fractures) were available for follow-up after a mean of 33.8 months (5.8 to 81). The absolute, age-related and side-related Constant scores were recorded. Of the 51 fractures, 46 (90.2%) healed primarily. Re-displacement of fragments or migration of Kirschner wires was seen in five cases. Necrosis of the humeral head developed in four patients. In three patients a secondary arthroplasty had to be performed, in two because of re-displacement and in one for necrosis of the head. There was one case of deep infection which required a further operation and one of delayed healing. The mean Constant score of the patients with a three-part fracture was 61.2 points (35 to 87) which was 84.9% of the score for the non-injured arm. In four-part fractures it was 49.5 points (18 to 87) or 68.5% of the score for the non-injured arm. The Humerusblock technique can provide a comfortable and mobile shoulder in elderly patients and is a satisfactory alternative to replacement and traditional techniques of internal fixation.
Objective: Arthroscopic reinsertion of the supraspinatus and infraspinatus tendons by means of imitation of an open trans osseous reinsertion technique.Indications: Tears in the tendon cuffs of the supraspinatus and infraspinatus muscles. Patients < 75 years of age. Contraindications: Retracted tendons that cannot be sufficiently mobilized to provide a tension-free reinsertion. Tears of the tendon cuff of the subscapsularis muscle. Surgical Technique: The free edges of the tendons are sparingly resected. The tendon attachment site on the greater tuberosity is freed of soft tissue and decorticated using an arthroscopic bone burr. A full-radius burr is used to drill insertion sites for the sutures in the tuberosity. A hollow needle is inserted percutaneously to puncture the free edges of the tendon for a single reinsertion suture. The hollow needle is then fed through the greater tuberosity to the lateral portal. The suture is guided through the needle and advanced via a working cannula. If the tear is > 2 cm in width, a mattress suture should be placed via another channel in the bone. This is to provide plane contact of the tendon to the reinsertion site. Postoperative Management: Restriction of movement using a shoulder bandage for 6 weeks after the operation. Results: In the 75 patients treated using a single suture, there was an improvement compared to the European Journal of Trauma Continuing Education The following is a reprint from Operat Orthop Traumatol 2006;18:1-18 and continues the new series of articles at providing continuing education on operative techniques to the European trauma community.related Constant Score from 55.8% before the operation to 80.4% at the follow-up examination, after an average of 26.8 months. The average age in this group was 58.2 years (range 35-75 years). In the 21 patients treated with a mattress suture, there was an improvement compared to the related Constant score from 59% before the operation to 83% at 14.3 months after the operation. The average age in this group was 58 years (range 35-75 years).The open transosseous suture is still the gold standard in the treatment of ruptures of the rotator cuff. However, in the last few years, the technique of arthroscopic reinsertion of the tendon stump has been standardized and definitely improved. There are various fixation systems for the arthroscopic surgical technique. Until now, it has not been clear whether a dowel or a suture-anchoring technique can provide reconstruction of the anatomy and breaking strength comparable to a transosseous suture [4,8,9]. We therefore developed an arthroscopic transosseous suture
