Table 1 Summary of outcome in included studies

From: Perforator-based flaps for the treatment of burn scar contractures: a review

Study Mean follow-up (range) Short-term follow-up Long-term follow-up Statistical analysis
Necrosis flap (%) ROM measurement Increase in ROM (preop → postop) Increase in flap size Outcome measures validated?
Ogawa [11] 5 years (1–8) 5/32 (16%) partial No
Er [9] Not mentioned 0/15 (0%) Shoulder abduction 112° (47 → 159) Goniometry: retrospective chart review No
Tsai [17] 11 months 0/40 (0%) Neck extension 24° (92 → 116) 15–38% ↑ flap width at 11 months Geometry/planimetry No
Lateral flexion 10° (26 → 36)
Ogawa [16] Not mentioned 4/41 (10%) partial No
1/41 (2%) complete
Rashid [12] 22 months (12–48) 2/27 (7%) epidermiolysis 63% ↑ flap width at 1 year Geometry/planimetry No
Waterston [18] 9 months (2–60) 1/23 (4%) complete Stretching of flap was observed No
Verhaegen [14] 8 months (3–14) 4/22 (18%) partial 16% ↑ flap surface area at 8 months Planimetry Yes
Tucker [13] Not mentioned 3/22 (14%) partial No
Wang [15] Not mentioned (range 1–5 years) 0/15 (0%) Neck extension and lateral flexion compared to normal ROM Postoperative extension and lateral flexion not significantly differing from normal ROM Flap geometry, measurement of cervical motion (Photo Measures software) Yes
Li [10] >1 year 1/15 (7%) partial Neck extension Neck extension >110° in all patients Goniometry No
