Article: Shoulder hemiarthroplasty for acute fractures of the proximal humerus: a minimum five-year follow-up.
[show abstract] [hide abstract]
ABSTRACT: Significant discrepancy in the functional outcome of hemiarthroplasty for proximal humerus fractures has been reported with short or mid-term follow-up. This study reports the long-term results and rate of complications of shoulder arthroplasty in the treatment of proximal humerus fractures. The review comprised 57 patients (44 women, 13 men) who underwent hemiarthroplasty between 1976 and 1996 as treatment of a proximal humerus fracture and who had a minimum 5-year follow-up (mean, 10.3 years). The mean patient age was 66 years at the time of surgery (range, 23-89 years). According to a modified Neer result rating system, results were satisfactory in 27 patients and unsatisfactory in 30. The mean active elevation was 100 degrees (range, 20 degrees -180 degrees ) and external rotation was 30 degrees (range, 0 degrees -90 degrees ). At the most recent follow-up, 9 patients (16%) had moderate or severe pain and 2 required implant revision or removal. The study data suggest that patients undergoing arthroplasty as treatment of an acute fracture of the proximal humerus may achieve satisfactory long-term pain relief; however, the result for overall shoulder motion is less predictable. In view of these results, current indications, surgical technique, and postoperative treatment may need to be revisited.Journal of shoulder and elbow surgery / American Shoulder and Elbow Surgeons ...

Article: Review of fixation techniques for the four-part fractured proximal humerus in hemiarthroplasty.
[show abstract] [hide abstract]
ABSTRACT: The clinical outcome of hemiarthroplasty for proximal humeral fractures is not satisfactory. Secondary fragment dislocation may prevent bone integration; the primary stability by a fixation technique is therefore needed to accomplish tuberosity healing. Present technical comparison of surgical fixation techniques reveals the state-of-the-art approach and highlights promising techniques for enhanced stability. A classification of available fixation techniques for three- and four part fractures was done. The placement of sutures and cables was described on the basis of anatomical landmarks such as the rotator cuff tendon insertions, the bicipital groove and the surgical neck. Groups with similar properties were categorized. Materials used for fragment fixation include heavy braided sutures and/or metallic cables, which are passed through drilling holes in the bone fragments. The classification resulted in four distinct groups: A: both tuberosities and shaft are fixed together by one suture, B: single tuberosities are independently connected to the shaft and among each other, C: metallic cables are used in addition to the sutures and D: the fragments are connected by short stitches, close to the fragment borderlines. A plurality of techniques for the reconstruction of a fractured proximal humerus is found. The categorisation into similar strategies provides a broad overview of present techniques and supports a further development of optimized techniques. Prospective studies are necessary to correlate the technique with the clinical outcome.Journal of Orthopaedic Surgery and Research 01/2011; 6:36. -
Article: Alternative humeral tubercle fixation in shoulder hemiarthroplasty for fractures of the proximal humerus
[show abstract] [hide abstract]
ABSTRACT: HypothesisWe hypothesize that the sling technique provides better long term tuberosity fixation in hemiarthroplasty for severe fractures of the proximal humerus.BackgroundAfter hemiarthroplasty for proximal humeral fractures, problems exist with deterioration of shoulder function by secondary displacement of the initially fixated humeral tuberosities. This study evaluated a new technique for fixation of the greater and lesser tuberosities in uncemented hemiarthroplasties in severely displaced 3- or 4-part proximal humeral fractures.Materials and methodsA consecutive series of 31 uncemented hemiarthroplasties using the new sling technique to repair the tuberosities was evaluated clinically and radiographically with special emphasis on the head-to-tuberosity distance (HTD). A historical cohort of 10 similar uncemented hemiarthroplasties was the control group in which the drill-hole technique was used for fixation of the humeral tuberosities.ResultsThe sling technique had an overall better tuberosity positioning in terms of HTD compared with the drill-hole technique (8 vs 1 mm; P = .025, U test). There were significantly more normal HTD values in the sling-technique group (81% vs 44%; P = .032, χ2 test). In the anatomic HTD group, the Constant score (70 vs 52; P = .009), patient satisfaction (7.1 vs 5.7; P = .038), and visual analog scale score (3.2 vs 5.2; P = .025) were statistically significantly superior compared with the nonanatomic HTD group.Conclusion and DiscussionThe sling technique for tuberosity fixation seems to provide solid fixation. In this study, anatomic HTD fixation was associated with significantly better functional outcome, patient satisfaction, and pain scores.Journal of Shoulder and Elbow Surgery.
