Open arthrolysis with pie-crusting release of the triceps tendon for treating post-traumatic contracture of the elbow.

BACKGROUND: Extensive loss of elbow flexion compromises the performance of daily activities. We examined the clinical outcomes of patients with post-traumatic extension contracture of the elbow treated with open arthrolysis and pie-crusting release of the triceps tendon. METHODS: We retrospectively reviewed the records of 7 patients (5 men and 2 women; mean age, 35 years) who underwent open arthrolysis via a combined lateral and medial approach with pie-crusting release of the triceps tendon for the treatment of post-traumatic elbow stiffness. All the patients had heterotopic ossification that restricted elbow motion and underwent removal of the ossified tissue and capsular release. The triceps tendon was gradually stretched by making multiple stab incisions on the tendon by using a No. 11 surgical blade. The range of motion of the elbow was recorded both preoperatively and at the final postoperative follow-up. Elbow function was assessed with the Mayo Elbow Performance Score. RESULTS: The patients were followed up for a mean of 24 months. After treatment, significant improvement was noted in the total arc of motion (from 44° to 116°, P <.001), mean flexion (from 80° to 124°, P < .001), and mean extension (from 31° to 8°, P = .004). The mean Mayo Elbow Performance Score improved significantly from 59 points preoperatively to 92 points at the final evaluation. No major postoperative complications developed in any of the patients. CONCLUSION: Our findings indicate that open arthrolysis with pie-crusting release of the triceps tendon is an effective and safe treatment approach for post-traumatic extension contracture of the elbow.

The time point in surgical excision of heterotopic ossification of post-traumatic stiff elbow: recommendation for early excision followed by early exercise.

BACKGROUND: Post-traumatic heterotopic ossification (HO) around the elbow may severely impair joint function. Although surgical excision is effective at restoring range of motion (ROM), traditional surgical treatment is postponed for at least 1 year to prevent recurrence, which leads to secondary contracture of the elbow. Because the optimal timing of resection is controversial, our study was performed to compare recurrence and elbow function between early and late excision in our patients to determine whether the delay is necessary. METHODS: We retrospectively reviewed 164 patients during a 4-year period. In the control group (112 patients), HO was excised at an average of 23.0 months after initial injury (range, 9-204 months); in the early excision group (52 patients), resection was performed at an average of 6.1 months (range, 3-8 months). HO recurrence was assessed by the Hastings classification system. Final ROM and Mayo Elbow Performance Scores were also evaluated. RESULTS: Recurrent HO was observed in 30 of 112 patients (26.8%) in the control group and 15 of 52 (28.9%) in early excision group. No significant difference in HO recurrence was found between the 2 groups (P = .942). Moreover, there were no notable differences regarding ROM, Mayo Elbow Performance Scores, and complications postoperatively. CONCLUSIONS: Early excision associated with early exercise is effective for the treatment of HO aiming at a low recurrence rate and satisfactory function. The conventional surgical delay of more than 1 year may be shortened.

Arthrolysis and delayed internal fixation combined with hinged external fixation for elbow stiffness associated with malunion or nonunion of capitellum fracture.

BACKGROUND: This study assessed outcomes after treatment of patients with capitellum fracture diagnosed >4 weeks after the trauma (delayed) who presented with stiff elbow. METHODS: We reviewed 7 patients with stiff elbows after delayed diagnosis of capitellum fractures between February 2007 and February 2012. They were treated with arthrolysis by twin incisions, late open reduction and internal fixation, and a hinged external fixator. According to the Bryan-Morrey-McKee classification, 3 patients had type I capitellum fractures and 4 patients had type IV. RESULTS: Mean follow-up was 28 months (range, 24-38 months). The mean delay from the initial trauma was 3.7 months. The flexion arc improved from a preoperative mean of 24° to a postoperative mean of 122°. The Mayo Elbow Performance Score increased from a mean of 56 points to 93 points. Anatomic fracture union occurred in all cases, and there was no secondary displacement. CONCLUSIONS: Arthrolysis, late internal fixation, and use of a hinged external fixator can solve problems associated with stiff elbow after delayed diagnosis of capitellum fracture. Combined use of these techniques may be a safe and effective treatment option.

Comparative study of radial head resection and prosthetic replacement in surgical release of stiff elbows.

PURPOSE: Elbow trauma can compromise the arc of elbow flexion and forearm rotation. This study aimed at comparing the outcomes of radial head resection and prosthetic replacement in the surgical release of post traumatic elbow stiffness and associated restriction in forearm rotation. METHODS: We retrospectively reviewed the data of patients who underwent open arthrolysis with radial head resection (n = 15; resection group) or radial head replacement (n = 19; replacement group). The pre- and postoperative measurements of the elbow range of motion (ROM) were recorded. Elbow function was evaluated by the Broberg and Morrey Evaluation System; the Mayo Elbow Performance Index (MEPI); and the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. RESULTS: Over a mean follow-up duration of 22 months, the improvement in the arc of flexion and extension was 79° (range, 45-125°) and 82° (range, 10-110°), while that in the ROM for forearm rotation was 96° (range, 40-150°) and 102° (range, 15-150°) in the resection and replacement groups, respectively. There were no significant intergroup differences in the elbow ROM measured at the last follow up. The Broberg and Morrey, MEPI, and Dash scores in the two groups were comparable. CONCLUSIONS: Both resection and prosthetic replacement of the radial head with open arthrolysis of post traumatic elbow stiffness were feasible in treating the associated restriction of forearm rotation. We recommend that if the elbow is stable after complete release, radial head resection is preferable to prosthetic replacement because it is technically less demanding.

Effect of cryotherapy after elbow arthrolysis: a prospective, single-blinded, randomized controlled study.

OBJECTIVE: To investigate the effect of cryotherapy after elbow arthrolysis on elbow pain, blood loss, analgesic consumption, range of motion, and long-term elbow function. DESIGN: Prospective, single-blinded, randomized controlled study. SETTING: University hospital. PARTICIPANTS: Patients (N=59; 27 women, 32 men) who received elbow arthrolysis. INTERVENTIONS: Patients were randomly assigned into a cryotherapy group (n=31, cryotherapy plus standard care) or a control group (n=28, standard care). MAIN OUTCOME MEASURES: Elbow pain at rest and in motion were measured using a visual analog scale (VAS) on postoperative day (POD) 1 to POD 7 and at 2 weeks and 3 months after surgery. Blood loss and analgesic consumption were recorded postoperatively. Elbow range of motion (ROM) was measured before surgery and on POD 1, POD 7, and 3 months after surgery. The Mayo Elbow Performance Score (MEPS) was evaluated preoperatively and 3 months postoperatively. RESULTS: VAS scores were significantly lower in the cryotherapy group during the first 7 PODs, both at rest and in motion (P<.05). There were no significant differences between the 2 groups in VAS scores at 2 weeks and 3 months after surgery. Less sufentanil was consumed by the cryotherapy group than the control group for pain relief (P<.01). No significant differences were found in blood loss, ROM, and MEPS between the 2 groups (P>.05). CONCLUSIONS: Cryotherapy is effective in relieving pain and reducing analgesic consumption for patients received elbow arthrolysis. The application of cryotherapy will not affect blood loss, ROM, or elbow function.
