BACKGROUND: The surgical treatment of displaced proximal humeral fractures is commonly affected by implant-related complications. We evaluated the functional and radiographic results of transosseous suture fixation in a series of displaced proximal humeral fractures (PHF).
METHODS: Sixty-four patients were retrospectively classified by age, sex, and the Neer fracture classification. Two-part greater tuberosity (2pGT) displaced fractures and 3-part (varus and valgus) and 4-part valgus impacted fractures were managed with fragment reduction and transosseous suture fixation. Patients with minimum follow-up of 24 months and assessed with the Constant-Murley score (CMS) were included. Radiological and medical complications, as well as reinterventions were also recorded.
RESULTS: Forty-six patients with a mean follow-up of 58 (24-132) and a mean age of 58 years old were analyzed. Patients with 2pGT (n = 10) fractures had a CMS of 76 points (59-89); patients with 3-part fractures (n = 22) had a score of 67 points (13-91); and those with 4-part fractures (n = 14) had a score of 64 (24-76) points. The overall complication rate was 6 out of 46, and 4 patients required reintervention for different reasons. Patients presenting with 3-part varus fractures had significantly lower functional outcomes scores (p = 0.007). Humeral head osteonecrosis was present in 9 patients and significantly affected the functional outcomes (p < 0.05). However, only three out of nine patients with osteonecrosis required subsequent surgery at the indicated follow-up.
CONCLUSIONS: The fracture reduction and transosseous fixation technique represents a safe technique with low complication and reintervention rates. The presence of humeral head necrosis did not lead to subsequent surgical intervention because no hardware had protruded.
LEVEL OF EVIDENCE: Level IV, retrospective study.
