Distal Humeral Fracture

The open distal humeral fracture associated with the major loss of the articular surface and bony structure is a challenging problem for orthopedic surgeons. In this case report, we describe a case of complete missing lateral column of the distal humerus with severe articular destruction of capitellum and lateral trochlear ridge which was treated with the patient-specific implant created with three-dimensional printing technology. Apart from anatomic replacement of the articular surface, the lateral collateral ligament complex and extensor muscle which are the key soft tissue stabilizers of elbow were repaired by reattaching their bony origins to the impacted iliac crest bone graft inside the implant. Due to the favorable result at 2-year follow-up, this modality is a potentially viable surgical option in treating of the severe open distal humeral fracture associated with entire lateral condylar damage.

Background: Plate and screw fixation during the treatment of distal humeral fracture in adults is considered to be a gold standard that makes anatomic and articular reduction. Injury of the ulnar nerve is a common condition that can be found in pre-operative, intraoperative, and postoperative. Intraoperative anterior subcutaneous transposition is still a controversial issue. Objective: To understand the variation of distance of the ulnar nerve during elbow motion with the anatomical landmark of distal humeral bone and plate position after fixation. Materials and Methods: The authors have studied ten fresh adult cadavers, who underwent autopsy at the Department of Forensic Medicine of Srinakharinwirot University. Results: The results showed that in zone 2, the Center of the medial condyle was the position of the distal humeral bone with the most variation in position changing during elbow flexion/extension. In the sagittal plane (+2.56 to –4.58 mm), the mean difference equaled to 7.14 mm, while in the coronal plane (+1.70 to –5.14 mm), the mean difference equaled to 6.84 mm, with the highest percentage of irritation up to 70%. Furthermore, 14 cases of ulnar nerve subluxation were found in 20 studies (70%). Conclusion: From the present study, the Medial condyle was the landmark with the most irritation and position changing of ulnar nerve during elbow flexion. The incidence of ulnar subluxation occurred after in situ release for plate fixation was also found higher than in previous studies.

Abstract Introduction Elbow flexion is indispensable for both functioning and nonfunctioning hands. It is well perceived that restoration of elbow function is the first reconstructive priority in cases of brachial plexus injuries. The authors assessed the impact of associated distal humeral fractures on the functional outcome after unipolar latissimus dorsi transfer (ULDT) for restoration of elbow flexion in patients with residual brachial plexus palsy (BPP). Patients and Methods Twenty-three patients operated for restoring elbow flexion after residual post-traumatic BPP (with or without distal humeral fracture) by unipolar latissimus dorsi transfer (ULDT) were reviewed for a retrospective study. Patients were divided into two groups; associated distal humeral fracture group (HF-group; 10 patients) and non-associated distal humeral fracture group (NHF-group; 13 patients). Elbow flexion active range of motion (AROM), flexion deformity in addition to Mayo Elbow Performance Score (MEPS) were assessed. Results In both groups there were statistically better postoperative MEPS grading (p = 0.007, p = 0.001, respectively) and scoring with a mean of 81 ± 16.1 and 90 ± 4.6, respectively (p < 0.001). The mean postoperative elbow flexion AROM was statistically better in both groups. The mean supination AROM was better in NHF group (p = 0.057). Conclusion The use of ULDT in residual post-traumatic BPP is an efficient procedure in regaining functional flexion and supination. An associated distal humeral fracture does not significantly affect the final functional outcome. Level of Evidence Level IV.

Significant Interference

SummaryThe purpose of this study was to compare the pin location and articular damage for intramedullary (IM) pins inserted into the humerus in a directed retrograde, non-directed retrograde, and normograde fashion. Proximal pin positioning in the humerus was significantly more cranial (p<0.05) using both retrograde techniques when compared to the normograde technique, although this did not cause significant interference with anatomical structures. The distance to the biceps tendon, transverse humeral ligament, and the distal pin location was similar with all insertion techniques, however two of ten pins passed in a non-directed retrograde fashion penetrated the shoulder joint. The results of this study suggest that although non-directed retrograde pinning cannot be recommended, either normograde or retrograde pins directed craniolaterally provide acceptable techniques for insertion of IM pins during distal humeral fracture repair.
