Objective To investigate the effectiveness of retrograde muscle release in treatment of mild to moderate type ischemic muscle contracture of forearm classified by Tsuge.Methods Between March 2010 and September 2018, 11 patients with mild to moderate ischemic muscle contracture of forearm were treated with retrograde muscle release. There were 6 males and 5 females with an average age of 24 years (range, 16-29 years). According to Tsuge classification, 6 cases were mild type and 5 cases were moderate type. The interval between injury and operation was 9 months to 25 years, with a median of 17 years. The scar cords in the muscle of the middle one-third of the forearm was released firstly. If the standard of sufficient release was not reached, further releasing the scar cords in the muscle and the tense tendon structure in the proximal one-third of the forearm and the origins of the flexor muscles was necessary. If the standard was still not reached, the origins of the flexor muscles can be released and slid. The effectiveness was evaluated from six aspects of the range of motion of the hand and wrist, dexterity, grip strength, sensation, subjective function scores [quick-disability of the arm, shoulder, and hand questionnaire (Quick-DASH) and the patient-related wrist/hand evaluation (PRWHE)] and satisfaction.Results All the incisions healed by first intention. Eight patients were followed up 1-106 months (median, 13 months). The range of motion of the hand and wrist was significantly improved, the results were excellent in 3 cases, good in 3 cases, and fair in 2 cases, with an excellent and good rate of 75%. The patient’s dexterity evaluation scored a perfect score of 12, which was close to the normal hand dexterity. At last follow-up, the grip strength on the affected side was 37.6%-95.5% of the contralateral side, with an average of 77.6%. Seven patients had normal sensation before and after operation, and the two-point discrimination of median nerve and ulnar nerve was 4-5 mm at last follow-up; 1 patient with forearm mechanical crush injury still felt numb after operation, and the two-point discrimination of median nerve and ulnar nerve was 8 mm and 7 mm, respectively. The Quick-DASH score was 0-15.9, with an average of 4.5, and the PRWHE score was 0-23.0, with an average of 6.6. All the patients were satisfied with the surgery and the effectiveness.Conclusion A targeted retrograde muscle release method for mild to moderate type ischemic contracture of forearm can achieve satisfactory effectiveness.
