To discuss the advantages of two flap contouring methods and to explore the best choice for the flap contouring. Methods From March 2002 to March 2006, 59 patients were admitted for a flapcontouring operation. Of the 59 patients, 40 (32 males, 8 females; average age, 34 years) underwent the multiphase lipectomy (the multiphase lipectomy group). The original flaps included the abdominal flap in 19 patients, the groin flap in 10, the thoracic flap in 4, the free anteriolateral thigh flap in 6, and the cross leg flap in 1. The flaps ranged in size from 6cm×4 cm to 32 cm×17 cm. However, the remaining 19 patients (16 males, 3 females; average age, 28 years) underwent the onephase lipectomy with skin graft transplantation(the onephase lipectomy group). The original flaps included the abdominal flap in 4 patients, the groin flap in 6, the thoracic flap in 3, and the free anteriolateral thighflap in 6. The flaps ranged in size from 4 cm×3 cm to 17 cm×8 cm. The resultswere analyzed and compared. Results In the multiphase lipectomy group, partial flap necrosis developed in 4 patients but the other flaps survived. The followedup of 27 patients for 3 months to 2 years revealed that the flaps had a good appearance and texture, having no adhesion with the deep tissues. However, the flaps became fattened in 22 patients with their body weight gaining. The patietns who had a flap gt; 5 cm×5 cm in area had their sensation functions recovering more slowly; only part of the sensations to pain and heat recovered. The two point discrimination did not recover. In the onephase lipectomy group, total graft necrosis developed in 1 patient but the healing was achieved with additional skin graft transplantation; partial graft necrosis developed in 2patients but the wounds were healed after the dressing changes; the remaining flaps survived completely. The followup of the 16 patients for 3 months to 3 years revealed that all the 16 patients had a good sensation recovery, 12 patientshad the two point discrimination lt; 15 mm, with no recurrence of the fattening of the flaps; however, the grafted skin had a more severe pigmentation, and no sliding movement developed between the skin and the tissue basement. Conclusion The multiphase lipectomy and the onephase lipectomy with skin graft transplantation are two skin flap contouring methods, which have their ownadvantages and disadvantages. Which method is taken should be based on the repair location of the 〖WT5”BZ〗skin flap and the condition of the skin flap.
ObjectiveTo assess the effectiveness of lateral ligament reconstruction with autogenous partial peroneus longus tendon for chronic lateral ankle instability.MethodsBetween September 2014 and November 2018, 32 patients (32 sides) with chronic lateral ankle instability were treated with lateral ankle ligament reconstruction by using autogenous anterior half of the peroneus longus tendon. There were 25 males and 7 females, with an average age of 28.5 years (range, 20-51 years). The disease duration was 6-41 months (mean, 8.9 months). The preoperative Karlsson-Peterson ankle score was 53.7±9.7. The talar tilt angle was (14.9±3.7)°, and the anterior talar translation was (8.2±2.8) mm. Six patients combined with osteochondral lesion of talus and 4 patients combined with bony impingement.ResultsAll incisions healed by first intention postoperatively. All patients were followed up 12-53 months (mean, 22.7 months). At last follow-up, the Karlsson-Peterson ankle score was 85.2±9.6; the talar tilt angle was (4.3±1.4)°; the anterior talar translation was (3.5±1.1) mm. There were significant differences in all indexes between pre- and post-operation (P<0.05). Seventeen patients were very satisfied with the results, 10 patients were satisfied, 4 patients were normal, and 1 patient was unsatisfied. After operation, the ankle sprain occurred in 7 cases, the tenderness around the compression screws at calcaneus in 5 cases, the anterolateral pain of ankle joint over 6 months in 4 cases. No patient had discomfort around the reciepient sites. At last follow-up, the ultrasonography examination showed that there was no significant difference in the density and diameter between bilateral peroneus longus tendons in 12 cases.ConclusionFor chronic lateral ankle instability, the lateral ankle ligament reconstruction with the autogenous partial peroneus longus tendon is a safe and effective surgical option.
Objective To investigate the effectiveness of free palmaris longus tendon graft reconstruction in the treatment of gouty tophus erosion lesions in flexor tendon of wrist and hand. MethodsA retrospective analysis was conducted on 8 patients with gouty tophus erosion lesions in flexor tendon of wrist and hand who underwent free palmaris longus tendon graft reconstruction between June 2017 and December 2023. All patients were male, aged 22-65 years, with an average of 45.9 years. The duration of gout history ranged from 2 to 18 years, with an average of 8.8 years. The duration from the discovery of gouty tophus to operation ranged from 12 to 26 months, with an average of 17.6 months. The gouty tophus eroded the flexor pollicis longus tendon in 4 cases, with Verdan flexor tendon zones being Ⅰ-Ⅱ in 1 case and Ⅳ-Ⅴ in 3 cases. The flexor digitorum profundus tendons were affected in 2 cases for the index finger, 1 for the middle finger, and 1 for the ring finger, all located in zone Ⅳ-Ⅴ. The long axis of the gouty tophus ranged from 2.3 to 4.5 cm, with an average of 3.4 cm. All 8 patients presented with limited finger flexion and extension. Among them, 4 cases were accompanied by median nerve compression symptoms, and 1 case had associated bone and joint destruction in the hand. The total active motion (TAM) of the affected finger was (81.3±30.2)° before operation according to the hand function evaluation criteria for tendon repair by the Chinese Society of Hand Surgery of the Chinese Medical Association, and the functional evaluation was poor. The harvested palmaris longus tendon intraoperatively was 7-9 cm in length. Results Surgical incisions in all 8 patients healed by first intention, with no infections, graft non-union, or significant adhesion complications. All patients were followed up 8-25 months, with an average of 14.8 months. Numbness symptoms resolved in all 4 patients who presented with median nerve compression symptoms. Patients did not experience wrist pain or other discomfort, and function was not compromised. At last follow-up, according to the hand function evaluation criteria for tendon repair by the Chinese Society of Hand Surgery of the Chinese Medical Association, the TAM of 8 patients was (197.5±55.8)°, which significantly improved when compared with that before operation (t=11.638, P<0.001); the hand function of 1 patient with gouty tophus in zone Ⅰ-Ⅱ flexor pollicis longus tendon was good, and the other 7 patients were excellent. ConclusionFree palmaris longus tendon graft reconstruction demonstrates good effectiveness in treating gouty tophus erosion lesions in flexor tendon of wrist and hand.
