OBJECTIVE: To investigate the difference of effectiveness between medial-lateral approach and posteromedian approach in the release of elbow stiffness after distal humeral fracture surgery. METHODS: A retrospective analysis was conducted on the clinical data of 41 patients with elbow stiffness following medial and lateral plate fixation for distal humeral fractures, admitted between January 2021 and June 2023 and meeting selection criteria. Patients were divided into the medial-lateral approach release group (study group, 20 cases) and the posteromedian approach release group (control group, 21 cases) based on surgical approach. Baseline data including age, gender, affected side, body mass index, disease duration, and preoperative extension angle, flexion angle, range of motion, visual analogue scale (VAS) pain score, Mayo elbow performance score, ulnar nerve symptoms, and heterotopic ossification showed no significant difference between groups ( P>0.05). The operation time, intraoperative blood loss, and complication incidence were recorded and compared between groups. Clinical effectiveness was evaluated using pre- and postoperative Mayo score, VAS score, elbow extension/flexion angles, and range of motion on the affected side. Statistical analysis focused on changes in these indicators relative to preoperative values. RESULTS: There was no significant difference in operation time and intraoperative blood loss between the two groups ( P>0.05). Patients in both groups were followed up 15-36 months, with a mean of 23.8 months; there was no significant difference in the follow-up time between the two groups ( t=-1.542, P=0.131). In the control group, 1 patient had obvious subcutaneous hematoma and 5 patients had poor wound healing within 2 months after operation, all of which were cured by symptomatic treatment, while no related complications occurred in the study group, there was a significant difference in poor wound healing incidence between the two groups ( P<0.05). At last follow-up, 2 patients in the study group and 3 patients in the control group had mild symptoms of ulnar nerve numbness, and there was no significant difference in the incidence of ulnar nerve symptoms ( P>0.05). All patients had no recurrence or new onset of heterotopic ossification, no skin necrosis or reoperation due to complications. At last follow-up, elbow extension angle, flexion angle, flexion-extension range of motion, VAS score, and Mayo score significantly improved in both groups when compared with the preoperative ones ( P<0.05). There was no significant difference between the change values in elbow extension angle and VAS score between the two groups ( P>0.05); the change values in flexion angle, range of motion, and Mayo score in the study group were significantly better than those in the control group ( P<0.05). CONCLUSION The medial-lateral approach can release the elbow stiffness and concurrently remove the medial, lateral, or posterior lateral plates. The incision minimizes disruption to rehabilitation exercises and reduces complications like inadequate wound healing, ultimately leading to improved treatment outcomes.

OBJECTIVE: To explore the effect of intravenous tranexamic acid on postoperative drainage and elbow joint function after traumatic elbow stiffness release. METHODS: The clinical data of 44 patients with elbow joint stiffness who were treated with release surgery between March 2022 and December 2023 and met the selection criteria were retrospectively analyzed. Among them, 20 patients were given intravenous infusion of 100 mL (1 g/100 mL, once a day) of tranexamic acid solution for 3 consecutive days after surgery (group A), and 24 patients were not treated with tranexamic acid after surgery (group B). There was no significant difference in baseline data such as gender, age, side, body mass index, initial injury, and preoperative hemoglobin, visual analogue scale (VAS) score, and Mayo elbow function score (MEPS), elbow flexion and extension activity between the two groups ( P>0.05). The drainage volume at 1 day and 3 days after operation, total drainage volume, drainage tube indwelling time, postoperative hospital stay, VAS score before operation and at 1, 2, and 3 days after operation, MEPS score before operation, at 3 months after operation, and at last follow-up, and elbow flexion and extension activity before operation and at last follow-up were recorded and compared between the two groups. RESULTS: Both groups of patients successfully completed the operation, and there was no significant difference in operation time ( P>0.05). The drainage volume at 1 day and 3 days after operation, total drainage volume, drainage tube indwelling time, and postoperative hospital stay in group A were significantly less than those in group B ( P<0.05). Both groups of patients were followed up 6-12 months, with an average of 8.6 months. No complications such as wound infection, elbow joint varus and varus instability or dislocation, and pulmonary embolism or other thromboembolic events occurred in either group. The VAS scores of both groups were significantly higher at 1 day and 2 days after operation than before operation ( P<0.05); the VAS score of group A was significantly lower than that of group B ( P<0.05). The VAS scores of both groups decreased to the preoperative level at 3 months after operation, and there was no significant difference between the two groups ( P>0.05). At 3 months after operation and at last follow-up, the MEPS scores of both groups significantly improved when compared with those before operation ( P<0.05); there was no significant difference between the two groups ( P>0.05). At last follow-up, the postoperative elbow flexion and extension activity of the two groups significantly increased when compared with that before operation ( P<0.05); there was no significant difference in change of elbow flexion and extension activity between the two groups ( P>0.05). CONCLUSION Intravenous tranexamic acid for 3 consecutive days after release of traumatic elbow stiffness can significantly reduce postoperative drainage volume, shorten drainage tube indwelling time and hospital stay, and relieve early postoperative pain, but it has no effect on the risk of thrombotic and embolic events and postoperative elbow function.
