OBJECTIVE: To conduct anatomical study on the iliac crest chimeric tissue flap and summarize its effectiveness of clinical application in repairing limb wounds. METHODS: Latex perfusion and anatomical study were performed on 6 fresh adult cadaver specimens with 12 sides, to observe the initial location, distribution, quantity, and direction of the common circumflexa iliac artery, the deep circumflexa iliac artery, and the superficial circumflexa iliac artery, and to measure their initial external diameter. Between December 2020 and September 2022, the iliac crest chimeric tissue flap repair was performed on 5 patients with soft tissue of limbs and bone defects. There were 3 males and 2 females, with an average age of 46 years (range, 23-60 years). Among them, there were 3 cases of radii and skin soft tissue defects and 2 cases of tibia and skin soft tissue defects. The length of bone defects was 4-8 cm and the area of skin soft tissue defects ranged from 9 cm×5 cm to 15 cm×6 cm. The length of the iliac flap was 4-8 cm and the area of skin flap ranged from 12.0 cm×5.5 cm to 16.0 cm×8.0 cm. The donor sites were directly sutured. RESULTS: Anatomical studies showed that there were 10 common circumflex iliac arteries in 5 specimens, which originated from the lateral or posterolateral side of the transition between the external iliac artery and the femoral artery, with a length of 1.2-1.6 cm and an initial external diameter of 0.8-1.4 mm. In 1 specimen without common circumflexa iliac artery, the superficial and deep circumflex iliac arteries originated from the external iliac artery and the femoral artery, respectively, while the rest originated from the common circumflex iliac artery. The length of superficial circumflex iliac artery was 4.6-6.7 cm, and the initial external diameter was 0.4-0.8 mm. There were 3-6 perforator vessels along the way. The length of deep circumflex iliac artery was 7.8-9.2 cm, and the initial external diameter was 0.5-0.7 mm. There were 3-5 muscular branches, 4-6 periosteal branches, and 2-3 musculocutaneous branches along the way. Based on the anatomical observation results, all iliac crest chimeric tissue flaps were successfully resected and survived after operation. The wounds at recipient and donor sites healed by first intention. All patients were followed up 8-24 months, with an average of 12 months. The tissue flap has good appearance and soft texture. X-ray film reexamination showed that all the osteotomy healed, and no obvious bone resorption was observed during follow-up. CONCLUSION The common circumflex iliac artery, deep circumflex iliac artery, and superficial circumflex iliac artery were anatomically constant, and it was safe and reliable to use iliac crest chimeric tissue flap in repairing the soft tissue and bone defects of limbs.

Objective: To explore the clinical effects of proximal ulnar artery perforator flap combined with iliac bone graft in the reconstruction of subtotal thumb or finger defects. Methods: A retrospective observational study was conducted. From August 2016 to August 2019, 7 patients with thumb or finger defects caused by mechanical damage who met the inclusion criteria were admitted to Ruihua Affiliated Hospital of Soochow University, including 6 males and 1 female, aged 46 to 58 years. Their length of fingers was repaired with iliac bone, with length of 2.0 to 3.0 cm. After the bone graft, the skin defect area of the affected finger ranged from 2.8 cm×2.2 cm to 6.0 cm×3.2 cm. Then the free proximal ulnar artery perforator flap with area of 3.0 cm×2.4 cm to 6.5 cm×3.5 cm was used to cover the wounds. The wounds in donor sites of iliac crest and flap were directly sutured. The survival of flap in one week post surgery and the donor site wound healing in 2 weeks post surgery were observed, respectively. During the follow-up, the appearance and sensory function of the affected finger, bone healing, and scar hypertrophy of wound in the donor site were observed and evaluated. At the last follow-up, the functional recovery of the affected finger was evaluated with trial standard for the evaluation of functions of the upper limbs of the Hand Surgery Society of Chinese Medical Association. Results: In one week post surgery, all the flaps survived. In 2 weeks post surgery, the iliac bone and the wounds in forearm donor site healed. During the follow-up of 5 to 13 months, the flap was good in appearance, without obvious pigmentation; the sensory recovery reached level S₂ in 5 patients and S₀ in 2 patients; all the grafted iliac bones were bony union without obvious resorption; the wounds in donor site healed well, with only mild scar formation. At the last follow-up, the shape of the reconstructed finger was close to the healthy finger, and the functional evaluation results were excellent in 3 cases and good in 4 cases. Conclusions: The use of proximal ulnar artery perforator flap combined with iliac bone graft to reconstruct subtotal thumb or finger can partially restore part of the appearance and function, with less damage to the donor site. It is a good choice for patients who have low expectations of appearance and function for the reconstructed finger.

Masquelet technique is one of the modalities for the treatment of long bone defect. Using cancellous bone graft to fill the bone defect is always a concern in children due to the small size of their iliac crest and open growth plate. We reported a case of 13-year-old male who presented with gap non-union of middle third of tibia. We applied a modified Masquelet technique by using only the cortical fibular graft instead of cancellous bone to fill the space surrounded by induced membrane. Fibula was used as a nonvascularized strut graft and matched stick graft to achieve complete union. We concluded that nonvascularized fibula grafting is an easy and effective option to fill the bone defect in children in the second stage of Masquelet technique.

PURPOSE: To compare the efficacy and safety of recombinant human bone morphogenetic protein (rhBMP) and iliac crest autograft in the fusion treatment of lumbar spondylolisthesis. METHODS: The studies using randomized controlled trials to compare the rhBMP with iliac crest autograft in the treatment of lumbar spondylolisthesis were retrieved from Embase, Pubmed, ProQuest dissertations & theses (PQDT), China national knowledge infrastructure (CNKI), Chinese Biomedical Database, Wanfang Data, Cochrane Library (from March 1998 to March 2018). Postoperative fusion rate, clinical success rate, postoperative intervertebral height, complications, operation time, blood loss and duration of hospitalization were chosen as the outcome indicators. Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical software Revman 5.3 was used for data-analysis. RESULTS: Eleven articles were included in the meta-analysis. The results showed that, comparing the efficacy of rhBMP with iliac crest autograft, statistical significance was found in the 24-month fusion rate post operation [95% CI (1.38, 24.70), p = 0.02] and operation time [95% CI (-14.22, -2.08), p = 0.008]. There is not sufficient evidence for statistical differences in the remaining indicators. CONCLUSION The current literature shows rhBMP is a safe and effective grafting material in the treatment of lumbar spondylolisthesis. Further evidence is dependent on the emergence of more randomized controlled trials with higher quality and larger sample sizes in the future.

OBJECTIVE: To investigate the clinical results of locking compression plate combined with autologous iliac bone graft in the treatment of aseptic ulnar nonunion. METHODS: From March 2009 to July 2017, 22 patients with aseptic ulnar diaphyseal nonunion with complete follow-up data were treated with surgery, including 12 males and 10 females, aged from 16 to 58 (39.7±9.9) years old and ranging in course of disease from 10 to 192 (39.4±55.7) months. There were 15 atrophic nonunions, 5 hypertrophic nonunions and 2 synovial pseudo-articular nonunions. After debridement of the nonunion, locking compression plate was used to fix the nonunion and autogenous iliac bone graft was given. Bone healing rate, surgical complications and clinical results were evaluated. RESULTS: All the patients were followed up, and the duration ranged from 13 to 42 months, with a mean of (22.5±8.2) months, and 1 patient did not heal. Visual analogue pain scores ranged from 0 to 3 (0.9±0.9). Pronation of forearm was 47 to 86 (69.0±14.7) degrees, supination was 35 to 85 (63.0±9.4) degrees, wrist flexion was 20 to 80 (51.0±10.2) degrees, wrist flexion was 32 to 88 (71.0±11.7) degrees, elbow flexion contracture was 0 to 25 (9.0±5.6) degrees, further flexion was 105 to 150 (134.0±13.9) degrees, and grip strength was 87% on the opposite side. According to the Anderson scoring system, 8 cases were excellent, 11 were satisfied, 2 were not satisfied, and 1 was failed. CONCLUSIONS LCP combined with autologous iliac bone graft can effectively treat aseptic ulna diaphyseal nonunion.

OBJECTIVE: To investigate the methods and clinical effects of autologous iliac bone transplantation, platelet-enriched plasma(PRP) and extracorporeal shock wave(ESW) in the treatment of nonunion. METHODS: From January 2015 to December 2016, 60 patients with nonunion were treated, including 41 males and 19 females, aged 18 to 42 years old with an average age of 29 years old. Patients with nonunion were divided into autologous bone transplantation treatment group(control group), autologous bone transplantation and platelet-rich plasma(PRP) combined with extracorporeal shock wave(ESW) treatment group(experimental group). The callus formation, local complications, final growth of fracture and Johner-Wruhs functional classification of operative limbs of the two groups were compared 3 months after operation. RESULTS: Fifty-five patients were followed up, 27 in the control group and 28 in the experimental group, 5 patients were lost. The follow-up period ranged from 8 to 24 months. The callus score in the control group was significantly lower than that in the experimental group at 3 months after operation(<0.05). There was no swelling and infection in the skin of the iliac bone acquisition site and non-union operation site in both groups. The clinical and bone healing time of the control group was significantly longer than that of the experimental group(<0.05). In the experimental group, 28 patients achieved bone union; in the control group, 24 patients achieved bone union, and 3 patients had bone nonunion again. The excellent and good rate of Johner-Wruhs functional classification of affected limbs in the control group was significantly lower than that in the experimental group(<0.05). CONCLUSIONS Autologous iliac bone transplantation combined with platelet-enriched plasma(PRP) and extracorporeal shock wave(ESW) has a certain effect in the treatment of bone nonunion after fracture surgery. It can significantly improve the formation of new bone. It is a comprehensive and useful way to treat bone nonunion after fracture surgery in clinical work.

Eight patients with femoral osteomyelitis were admitted in Lanzhou General Hospital of PLA between July 2012 and July 2015. During the operation the femur was fixed with non-contact locking plate after thorough debridement. Iliac morselized cancellous bones without cortical bone were filled in the bone defect after debridement. The locking plates were placed in the lateral subcutaneous interface superficial to the vastus lateralis muscle. Drainage tubes were routinely placed postoperatively. The surgery was completed successfully in all patients, and the average operation time was (130±10) min (120-150 min). Intravenous antibiotics were administrated for 2 weeks and followed by 4 week-oral antibiotics after the operation in all 8 cases. Drainage tubes remained in situ about 8 days. All patients were followed up for 12-48 months, with an average of (19±7) months. Postoperative X-ray examination showed bone union in 7 cases with an average healing time of (16±5) weeks. One patient failed with relapsed infection, and was later treated with Ilizarov apparatus after secondary debridement. No plate and screw fracture, loose and fixation failure were observed in all 8 cases.

OBJECTIVETo investigate the reconstruction of thumb II-III degree defect by big toe wrap-around flap combined with second toe proximal interphalangeal joint.

METHODSBetween May 2004 to July 2012, 25 cases with thumbs II-III degree defects were treated. The ipsilateral big toe wrap-around flap combined with second toe proximal interphalangeal joint was designed to reconstruct the thumb defects based on the thumb size on the healthy side. The distal end of hallux was covered by flap at tibial side. The wound at the fibula side was covered by skin graft and flap. The bone defect at the second toe was filled with remnant hallux or iliac bone.

RESULTSAll the 25 reconstructed thumbs survived completely. The patients were followed up for 6-26 months without any joint degeneration. According to the finger reconstruction functional criterion publicized by China Medical Association, the finger function was assessed as excellent in 10 case, good in 11 cases, poor in 4 cases. Joint necrosis happened in 2 cases and bone malunion in 2 cases. The 4 cases received dead bone debridement and iliac bone graft. No malfunction occurred in the donor site.

CONCLUSIONSOur surgical method is a currently effective way to reconstruct II-III degree thumb defects. Satisfactory functional and cosmetic results can be achieved both in donor site and recipient site.

OBJECTIVETo investigate the effect of vascularized composite flap with iliac crest and nternal oblique muscle of abdomen for half mandibular reconstruction.

METHODSFrom July 2009 to Sept. 2013, 14 cases with half mandibular defect after tumor resection were treated with composite flap of iliac crest and internal oblique muscle of abdomen pedicled by deep circumflex iliac vessels. During operation, one group performed tumor resection and got the recipient area vessels ready for anastomosis. The other group performed harvesting of composite flap. Then the flap was trimmed and fixed to construct the defect with vessel anastomosis.

RESULTSAll the 14 composite flaps survived with local infection only in 1 case. The size of harvested iliac crest ranged from 6 cm x 3 cm to 9 cm x 3 cm. The size of harvested internal oblique muscle of abdomen ranged from 5 cm x 4 cm to 7 cm x 5 cm. The patients were followed up for 6 months to 26 months (mean, 13 months) with satisfactory results and no complication. Mandibular panoramic radiographs showed new bone formation and good union.

CONCLUSIONSVascularized composite flap with iliac crest and internal oblique muscle of abdomen has the advantages of abundant bone volume, as well as soft tissue reconstruction in one stage. The reconstructed mandible can attain normal function and appearance.
