【Abstract】 Objective To evaluate the effects of allogeneic bone graft for reconstructing bone defect of clavicle aftertumor resection. Methods Nine patients received the surgical procedures for repairing and reconstructing bone defect afterresection of clavicle tumor from January 2000 to January 2006. There were 4 males and 5 females aged 12 to 68 years. Two patientswere diagnosed as having benign tumor and tumor-like lesion(stage Ⅲ according to Campanacci grading), and 7 as having primarymalignant tumor and metastatic cancer. Three lesions were located in acromial end, 2 in sternal end and 4 in shaft of clavicle. Twocases was accompanied by pathological fracture. According to Enneking’s functional evalutation, the results were excellent in 3 cases,good in 3 cases, fair in 1 case and poor in 2 cases. Based on the visual analogue scale (VAS), pain was rated as medium rest-pain in4 cases, as medium move-pain in 3 cases and heavy pain in 2 cases preoperatively. The tumor was resected with en bloc. Defectedclavicles were reconstructed by a part of allograft clavicle and plate. The patients with malignant tumor received neo-adjuvant chemotherapyand radiotherapy postoperatively. The results were evaluated according to control of tumor, rel ief of pain, bone healingand shoulder joint function. Results These patients were followed up 12 to 70 months (mean 34.6 months). There were no localrecurrence and metastases in all patients during the follow-up. No complications of immune rejection and deep infection wereseen. The normal shape of the shoulders was restored. Eight of all patients showed primary bone healing between allograft boneand host bone. The mean healing time was 5.4 months (3.2-6.8 months). Loosening of the plate and nonunion were seen in 1 case;and bone grafting was given again. Fracture of allograft occurred in 1 case after removing internal fixation. According to Enneking’s functional evulation, the results were excellent in 6 cases and good in 3 cases at 3 months after operation; excellent in 4 cases, goodin 1 case and fair in 1 case among 6 patients who were followed up for 24 months. The VAS results of postoperation showed l ightmove-pain in 2 cases at 3 months, l ight move-pain and medium move-pain in 1 case respectively and no pain in 7 cases 12 months after operation. Conclusion Allogeneic clavicle is a useful and rel iable reconstructive material for clavicle defect due to tumor resection. The satisfactory shape and favorable function of the shoulder may be recovered after this procedure.
Objective To investigate the result of tissue flap transferring for wound repair of the clavicle. Methods From 1994 to 2000, 3 patients( 1 withclavicle osteosynthesis, 1 with chronic clavicle osteomyelitis, and 1 with radioactive ulcer in clavicular region accompanied by chronic osteomyelitis of clavicle) were reconstructed with turnover adipofascial flap, myocutaneous flap of pectoris, and myocutaneous flap of latissimus dorsal respectively. The outcome was observed. The operation principles of tissue flaps transferring for wound repair of the clavicle were summarized. Results Follow-ups were done for 2 months to 7 years. All tissue flaps survived well and the wounds in clavicular region were healed well. There was no recurrence of chronic clavicle osteomyelitis. Conclusion Turnover adipofascial flap, myocutaneous flap of pectoris and latissimus dorsal are often used for wound repair of theclavicle. Most of the wounds of the clavicle can be repaired by turnover adipofascial flap. Myocutaneous flap of pectoris and latissimus dorsal are more suitablefor wound repair with chronic clavicle osteomyelitis. In the case of radioactive ulcer of the clavicular region, myocutaneous flap of latissimus dorsal transposition is a better alternative for wound repair.
Objective To analyze the epidemiological features of clavicle fractures.Methods A total of 363 cases of clavicle fractures were treated from February 1993 to November 2002, their case history data were reviewed and evaluated by epidemiological method.Results Out of 363 cases, there were 269 males and 94 females, aged from new born to 96 years. The locations of fractures were on left side in 159 cases and on right side in 204 cases. Neonatal clavicle fracture occurred in the case of delivery (0.28%). The causes of disease for adult clavicle fractures were traffic injury (52.1%) and daily falling injury(31.1%). There were232 cases of simple fractures and 131 cases of comminuted fractures. The fracture positions included inner(6 cases), middle(328 cases) and outer parts(29 cases). Multiinjuries occurred in 78 cases, the rib fractures concomitant with clavicle fractures were the commonest(31 cases).Conclusion The clavicle fractures are the common injury. Of them, traffic injury and daily falling injury arethe most common. The rib fractures are always accompanied with clavicle fractures.The main position of fracture is on the middle part.
Clavicle fracture is a common orthopedic injury, accounting for approximately 2.6%-4% of all adult skeletal fractures. In 2023, the American Academy of Orthopaedic Surgeons (AAOS) developed evidence-based treatment guidelines for clavicle fractures, which include 4 recommendations and 10 options. This article, based on a thorough review of the guidelines, discusses the clinical treatment of clavicle fractures, aiming to share advancements and the latest diagnostic and therapeutic considerations with orthopedic colleagues to enhance treatment outcomes.
