Objective Exploring the clinical efficacy of using autologous rib cartilage grafting to reconstruct finger hemiarticular defects.Methods From August 2022 to February 2024,for 6 patients with hemiarticular surface defects in the metacarpophalangeal joints and interphalangeal joints of 8 fingers,costal cartilage was used for joint remodeling and transplantation to reconstruct the hemiarticular surface defects of the fingers.All 8 joint transplants in 6 patients were two-stage surgeries.In the first stage,antibiotic bone cement was used to fill the space-occupying lesions,and in the second stage,costal cartilage joint remodeling was performed to reconstruct the finger joint defects.Postoperative follow-up and assessment of fracture healing according to Paley fracture healing scoring criteria.Outpatient and WeChat follow-up,upper limb function is evaluated according to the upper limb functional assessment standards of the Chinese Medical Association Hand Surgery Society.Record VAS pain score.Results In this group,there were a total of 6 patients with 8 cases of hemiarticular defects.Among them,2 patients had two joint surgical sites,while the remaining 4 patients had a single joint surgical site.There were 2 cases of metacarpophalangeal joint head defects,2 cases of proximal articular surface defects,3 cases of proximal articular head defects,and 1 case of thumb proximal articular head defect.After surgery,8 out of 6 patients'hand wounds healed successfully.All patients were followed up for 6-12 months postoperatively,with an average of 9 months.The VAS pain score(affected finger)for the last follow-up was 0-2 points,with an average of 0.6 points.According to Paley's scoring criteria,all 6 patients had excellent fracture healing.According to the evaluation criteria for upper limb functional assessment of the Chinese Medical Association Hand Surgery Society,3 cases were rated as excellent,3 cases were rated as good,and 2 cases were rated as fair.Conclusion For patients with half joint defects on one side of the finger,rib rib cartilage was used for joint reconstruction,which significantly improved the joint shape and function at the defect site,and reduced joint pain scores.

Objective:To explore the short-term efficacy on 3D printing assisted reconstruction of traumatic digit joint defects using rib and costo-osteochondral autograft.Methods:From August 2022 to July 2023, 7 patients with open digit joint defects had undergone emergency primary debridement and fracture fixation in the Department of Orthopaedics, 988th Hospital of the Joint Logistics Support Force of PLA. Patients with more phalangeal defects that could not be aligned were treated with antibiotic bone cement filling in the emergency surgery. In the second stage surgery, bone cement was removed and transfer of rib cartilage graft was performed to reconstruct the digit joint defect. According to a 1∶1 3D printed hand templates, rib cartilage grafts were crafted to the shape of digit joints, and then spliced together the digit joints and bone defects for fixation. Follow-up X-ray examinations were taken and assessment of the healing status of rib and fractures of phalangeal and metacarpophalangeal bones were carried out according to the Paley fracture healing score. At the outpatient follow-up, assessment of transferred joint movement and evaluation of upper limb function were conducted according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. Visual Analogue Scale (VAS) pain scores were evaluated from the affected digits and donor sites.Results:After reconstructive surgery, all 7 patients had primary healing of the wounds of hand. One patient had fat liquefaction at the donor site, and the rest had primary donor site healing. One patient received further surgery for extensor tendon repair after rib cartilage grafting due to the digital extensor tendon injury. All 7 patients were included in postoperative follow-up for 6-11 months, with an average of 9 months. All patients had excellent fracture healing according to the Paley fracture healing score. At the final follow-up, the extension and flexion of the digit joints were found at 40°-80° (average 56.2°) for proximal interphalangeal joints (4 patients), and 10° in extension and 85° in flexion for metacarpophalangeal joint (1 patient). The range of motion of the thumb interphalangeal joint (2 patients) was 20°-35° (average 27.5°). Hand function was assessed according to Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association and it was found that 3 patients were in excellent, 3 in good and 1 in fair.Conclusion:This study focused on the treatment of traumatic digit joint defects by transfer of individually crafted rib cartilages in reconstruction of the defected digit joint. It significantly improves the appearance and function of the defected digit joints, especially suitable for the irregular defects of phalangeal bones.

Objective To investigate the medicated side warm nest pot combined with letrozole in the treatment of multiple bursal ovarian syndrome (PCOS) superiority of the clinical treatment of kidney deficiency syndrome in ovulation dysfunction infertility,provide the basis for clinical treatment. Methods 78 cases of infertile patients(randomly selected from January 2014 to June 2015 hospitalized in Hainan Medical University Hospital) due to kidney deficiency syndrome in patientswith ovulatory dysfunction resulting from PCOS. 39 cases in the control group received oral letrozole only. 39 cases in experimental group took oral warm nest pot combined with letrozole,continuous treatment for four menstruation cycle. Adverse reactions,ovulation rate,pregnancy rate and safety index of the two groups before and after treatment of menstruation were observed and recorded. Results The effective rate of the control group was 74.36%,and the effective rate of the experimental group was 87.18%. The difference was statistically significant(P < 0.05). The ovulation rate of the control group was 47.71%,which was lower than that of the experimental group (79.07%),and the difference was statistically significant (P < 0.05). The pregnancy rate in the control group was 12.82%,while that in the experimental group was 33.33%,and the difference was statistically significant (P < 0.05). Patient′s irregular menstruation improved in the two groups , while the experimental group did better than the control group. Conclusion Effect of warm nest pot combined with letrozole on kidney deficiency syndrome of ovulation dysfunction in PCOS is remarkable ,with little side effects.
