From: Management of chronic unstable acromioclavicular joint injuries

Study n Type of treatment Mean follow-up Results
Weinstein et al. [6] 44 Modified Weaver–Dunn technique in 15/27 acute cases, and in 14/17 chronic cases. The rest of the repairs were performed by means of AC non-absorbable sutures 4 years (range 2–9) Satisfactory results in 96% of acute cases and 76% of chronic cases. The differences were statistically significant in favor of acute cases
Rolf et al. [11] 49 29 patients using the modified Phemister technique versus a group of patients who underwent surgery after failure of conservative treatment (20 modified Weaver–Dunn) 53 months (range 20–92) The results were significantly superior in the group of patients managed in the acute phase
von Heideken et al. [12] 37 22 patients treated in the acute phase versus 15 patients treated in the chronic phase. Hook plate in all cases 22 acute patients were re-evaluated at average of 38 months (range 15–96 months) after surgery, and 15 chronic patients were re-evaluated at an average of 36 months (range 18–62) after surgery The results significantly favored both the clinical and radiological aspects, to the group of patients treated in the acute phase
Mignani et al. [13] 40 25 patients in the acute phase versus 15 patients in the chronic phase. In both groups the management consisted of AC and CC temporary fixations with K-wires Unknown Satisfactory results in 100% of patients in the acute group and 93% of patients in the chronic group. No statistically significant differences
Dumontier et al. [14] 56 32 patients in the acute phase versus 24 patients in the chronic phase. All patients were treated by means of CA ligament transposition Acute group (mean follow-up 46 months) and chronic group (mean follow-up 51 months) The results were satisfactory in 81% of patients treated in the acute phase and in 79% of patients treated in the chronic phase, with no significant differences
