The aim of the study was to analyze the results of primary tendon
reinsertion in acute and chronic distal triceps tendon ruptures
(DTTRs) in the general population. A total of 28 patients were operated on for primary DTTR reinsertions,
including 21 male patients and seven female patients with a mean
age of 45 years (14 to 76). Of these patients, 23 sustained an acute
DTTR and five had a chronic injury. One patient had a non-simultaneous
bilateral DTTR. Seven patients had DTTR-associated ipsilateral fracture
or dislocation. Comorbidities were present in four patients. Surgical
treatment included transosseous and suture-anchors reinsertion in
22 and seven DTTRs, respectively. The clinical evaluation was performed
using Mayo Elbow Performance Score (MEPS), the modified American
Shoulder and Elbow Surgeons Score (m-ASES), the Quick Disabilities
of the Arm, Shoulder and Hand score (QuickDASH), and the Medical
Research Council (MRC) Scale.Aims
Patients and Methods
A particular pattern of complex instability of the elbow is “the terrible triad”, in which elbow dislocation is associated with fractures of the coronoid and radial head. Other frequent patterns are the variant of Monteggia lesions (Bado II) described by Jupiter which is characterized by ulnar fracture associated with fracture-dislocation of proximal radius, and the articular fracture of the distal humerus associated with elbow dislocation. The goal of treatment is to restore the primary stabilizers of the elbow such as the coronoid process, olecranon and both collateral ligaments by internal fixation and reconstruction of the ligaments. If elbow stability obtained at operation is unsatisfactory or internal fixation not enough stable, there an indication for applying a dynamic external fixator (DEF). The latter allows:
the articular congruence to be maintained and the ligaments to heal in adequate tension and position, internal fixation and ligaments reconstruction to be protected, and immediate joint motion to be carried out. From 2005 to 2008, we treated surgically 31 patients with complex instability of the elbow. DEF was applied in 38% of cases, namely 3 terrible triads, 5 fracture-dislocations of Monteggia and 4 articular fractures of the humerus associated with elbow dislocation. The mean age of patients was 44 years (range 30–74). All patients underwent ORIF, reconstruction of ligaments and dynamic external fixation. The OptiROM elbow fixator was used In 2 patients, the Orthofix fixator in 1 and the DJD fixator in 9. In all cases, active elbow motion was allowed without restrictions from the second postoperative day. Indomethacin was consistently administered for 5 weeks to prevent heterotopic ossifications. The DEF was removed after 6 weeks. The mean follow-up was 25 months (range 5–44 months). At last follow-up, the clinical results, evaluated according to the MEPS, were excellent in 10 patients (83%), who had had a fast recovery of range of motion (ROM). The elbow was painless in all patients and stable in all but 1. Moderate osteoarthrosis was found in 60% of cases. Complications included: 1 elbow stiffness, 1 pseudarthrosis of capitulum humeri and trochlea, 1 transitory radial nerve palsy, and 1 superficial pin tract infection. In conclusion, DEF is a helpful tool for treatment of complex elbow instability, particularly when stable internal fixation cannot be obtained or instability persists after ligaments reconstruction. However, DEF increases morbidity, and implies a longer operative time and prolonged exposure to radiation.
determining the possible presence of anatomical variations of the safe-zone and analyzing the anatomical congruence of precontoured plates to this zone.
(flat) (25 %), (slightly concave) (63,6 %) and (markedly concave) (11,4 %), Adherence of a precoundered plate (Acumed) to the bone surface of the safe zone was performed independently by three of us, and the gap between plate and bone was measured. Plate adaptability was good in Type B, scarce in Type C and absent in Type A.
