The results of surgical treatment of post-traumatic elbow contractures in adolescence have been conflicting in the literature. Some authors suggest that contracture release in this age group is less predictable and results less favorable than in adults. A retrospective review of the senior author’s patients produced 16 patients under the age of 21 that had post-traumatic elbow contracture releases. Three patients with arthroscopic releases and one patient lost to follow up were excluded from this study.

Twelve adolescent patients (mean age 16.7 years, range 13–21) had open release of post-traumatic elbow contractures. All releases were initiated through a lateral approach with anterior capsular release and were supplemented by posterior release (in 4 patients) through the same incision. Medial-sided pathology was addressed through a separate medial incision in 3 patients. In three patients the radial head was excised. Muscle lengthening was used in only one patient.

The mean follow-up was 18.9 months (range 10–42 months). Preoperative flexion was increased from 113 to 129deg (p< 0.01), extension from −51 to −15deg (p< 0.001) for a mean total gain of 54deg in the flexion-extension arc (p< 0.001). Pronation was improved from 58 to 77deg and supination from 56 to 62deg, but these improvements did not reach statistical significance. At the final follow-up the patients maintained 93% of the motion that was achieved intraoperatively. All patients achieved a functional ROM of at least 100deg in the flexion-extension arc. No patient lost motion. One patient had a superficial infection that was treated conservatively

Our experience with post-traumatic contracture release in adolescent patients has been rewarding; all patients reached a functional range of motion. The advantage of the lateral approach used in these patients is that it allows simple and safe access to the anterior capsule, which is often adequate to regain full extension. Through the same approach the posterior structures can also be addressed without violating the lateral collateral ligament. The medial approach is more demanding and was reserved only for patients with medial sided pathology. Fractional musculotendinous lengthening was rarely necessary in post-traumatic contractures. Open release in adolescent patients with congruent stiff elbows has yielded satisfactory results in our hands.

Despite the widespread use of demineralized bone matrix (DBM) allografts there are few clinical studies comparing DBM to iliac crest bone grafting (ICBG). A comparison of DBM to ICBG is presented in patients who underwent four corner fusions of the wrist by one surgeon using identical operating technique.

The senior author’s first fourteen consecutive patients in which DBM was used for four corner fusion were compared with fourteen patients selected from a total of 48 patients in which ICBG was used. The ICBG group was matched for age, indication and healing impairing co-morbidities (mainly smoking). Patient radiographs from the 8th, 12th and 24th postoperative week follow up were digitized and blinded. Three orthopaedic surgeons, not involved in the patients care, rated the degree of bony union in a scale of 0 (no evidence of healing) to 3 (solid bony healing). The operating technique and fixation was identical in all patients. K-wires were removed at a mean of 8.2 weeks for DBM and 7.7 weeks for the ICBG group.

All patients had a minimum follow-up of one year. All fusions healed both radiographically and clinically without complications. Review of the radiographs revealed significantly less visible healing at 8 weeks in the DBM group (mean score 1.50 versus 1.74 of the ICBG group, p< .05). Lower scores were also obtained for the DBM group at 12 and 24 weeks but they did not reach statistical significance.

In this study both DBM and ICBG were equally effective in achieving solid bone union for intercarpal fusions. However, the statistical power of this series is not adequate to conclude that healing rates are equal between the two graft materials. The radiographic appearance of bridging bone lagged behind in the DBM group. The biological significance of this finding is not clear; it could indicate delayed mineralization at the fusion site. Such a delay may be significant in graft choice for patients with healing impairment.
