Objective
To investigate the clinical application of micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist to repair skin defect of finger.
Methods
Twenty-six cases (26 fingers) with skin defect of finger were repaired with micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist between December 2011 and February 2013. There were 20 males and 6 females with the average age of 31.5 years (range, 20-56 years). The causes of injury included cutting injury in 20 cases and crushing injury in 6 cases. The time from injury to admission was 1-5 hours with an average of 2 hours. Injured fingers included thumb in 6 cases, index finger in 6 cases, middle finger in 6 cases, ring finger in 4 cases, and little finger in 4 cases; the locations were the dorsal side of the finger in 6 cases, lateral side in 6 cases, and the volar of the finger tip in 14 cases; there were 4 cases on the proximal phalangeal skin, 8 cases on the middle phalangeal skin, and 14 cases on the distal phalangeal skin. The defect area ranged from 2.0 cm × 1.5 cm to 4.0 cm × 2.0 cm, and the flap area ranged from 2.5 cm × 2.0 cm to 4.5 cm × 2.5 cm. All the donor sites were directly sutured.
Results
The flaps of 25 cases survived well after operation, and wound healed by first intention； 1 case had partial necrosis and the wound had a scar healing by changing dressing. All cases were followed up 6-12 months (mean, 10 months). The color and appearance of the flaps were satisfactory with tender texture. The two-point discrimination of the flap was 5-8 mm (mean, 6.8 mm). The donor sites healed primarily without scar contracture and limitation of wrist flexion or extension.
Conclusion
The micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist is a good option to repair skin defect of finger. It has the advantages of hidden donor site, the same operative field, great comparability of flap and finger skin, and it can be used as a vascularized tendon or nerve graft.
Since 1985, on the basis of anatomical observation of 50 fresh adult specimens, we designed the transposition oF vascularized capitate bone carrying the dorsal branche of the anteriot interosses artery to replace the damaged lunate bone from avascular necrosis. The operation had been done in 6 patients and the follow-up observation (from 6 months to 4 years) showed that the operation was satisfactory. The anatomic basis, the advantages and disadvantages, and the surgical indications were discussed.
Objective To investigate the cl inical outcome of treating dorsal wrist gangl ion with an improved surgical strategy by excising the gangl ion completely along their stalk and repairing the dorsal carpal l igaments under brachial anesthesia. Methods From March 2005 to January 2007, 34 patients with dorsal wrist gangl ion were treated and studied retrospectively. There were 14 males and 20 females, aged 25-65 years (43 years on average). The left sides were involved in 22 cases and right sides in 12 cases. Thirteen cases of relapse received excision for 1 to 4 times under local anesthesia, with amean period of 17 months (14 days to 7 years) from excision to recurrence. Twenty-one patients were first attack cases with a mean period of 11 months (15 days to 8 years) from diagnosis to excision. The size of the gangl ion ranged from 1.5 cm × 1.2 cm to 4.5 cm × 4.0 cm. Now, each surgical process was performed under brachial anesthesia, and a pneumathode tourniquet was used. In 6 patients, the stalks of gangl ion did not invade the carpal l igaments, and gangl ion was removed completely without immobil ization after operation. In 28 patients, the stalks of gangl ion invaded the carpal l igaments, gangl ion was excised completely along its stalk to the dorsal carpal structure; the l igaments were sutured directly in 16 cases and were repaired with adjacent tissue such as the wall of sheathing canal of extensor tendon in 12 cases. The wrists were immobil ised for 3 weeks. Results Primary wound heal ing was achieved in all incisions. All patients were followed up for 26-36 months with an average of 31.5 months. Only 2 cases (5.9%) recurred. The range of motion of the wrist remained normal and the symptom of the dorsal wrist was rel ieved sl ightly. Patients’ satisfaction score ranged from 60 to 100, with an average of 83.8. Conclusion The gangl ion should be excised completely together with defect repair of dorsal carpal l igament under brachial anesthesia and the wrist immobil ised for 3 weeks, the recurrence rate will be reduced greatly.

ObjectiveTo review the research progress of wrist arthroscopy assisted treatment of distal radius fractures.MethodsTo summarize and describe the anatomical characteristics and fracture classification of the distal radius, indications and contraindications of wrist arthroscopy-assisted treatment, surgical methods, and associated soft tissue injuries, and summarize the advantages and disadvantages of the operation through a large number of literature at home and abroad on the treatment of distal radius fractures assisted by wrist arthroscopy.ResultsWrist arthroscopy as a minimally invasive technique for the treatment of distal radius fractures, compared with traditional surgery, can accurately observe intra-articular damage and perform operations under the microscope to avoid secondary damage to blood vessels, nerve, and tendon, etc., and can achieve one-stage repair and reconstruction by repairing the ligament, trigonal fibrocartilage complex, and carpal dislocation. It has the advantages of less trauma, fast postoperative recovery, extensive indications, fewer complications, and satisfactory effectiveness.ConclusionWrist arthroscopy has advantages that traditional X-ray film, CT, MRI, and arthrography examinations do not have. Moreover, wrist arthroscopy has achieved satisfactory effectiveness in the adjuvant treatment of intra-articular distal radius fractures.
ObjectiveTo summarize the effectiveness of nitinol memory alloy two foot fixator with autologous cancellous bone grafting in treating old scaphoid fracture and nonunion.MethodsBetween January 2013 and January 2017, 11 patients of old scaphoid fracture and nonunion were treated with nitinol memory alloy two foot fixator and autologous cancellous bone grafting. All patients were male with an average age of 26.1 years (range, 18-42 years). The fractures were caused by sport in 3 cases, falling in 7 cases, and a crashing object in 1 case. The interval between injury and operation was 6-18 months (mean, 8.9 months). Postoperative outcome measures included operation time, fracture healing time, grip strength, range of motion (ROM) of flexion, extension, ulnar deviation, and radial deviation, Mayo score, visual analogue scale (VAS) score, and the Disabilities of the Arm, Shoulder, and Hand (DASH) score.ResultsThe operation time was 35-63 minutes (mean, 48 minutes). All incisions had primary healing with no infection and loosening or breakage of internal fixator. All patients were followed up 12-30 months (mean, 20.7 months). X-ray films showed that fracture healing was achieved in all patients with an average time of 15 weeks (range, 12-25 weeks). All internal fixators were removed after 10-12 months of operation (mean, 11.2 months). At last follow-up, the grip strength, ROMs of flexion, ulnar deviation, and radial deviation were superior to those before operation (P<0.05), no significant difference was found in ROM of extension between pre- and post-operation (t=0.229, P=0.824). There were significant differences in above indexes between affected and normal sides (P<0.05). At last follow-up, the Mayo, VAS, DASH scores were also significantly superior to those before operation (P<0.05).ConclusionFor the old scaphoid fracture and nonunion, Ni-Ti arched shape-memory alloy fixator and autologous cancellous bone grafting can obtain good effectiveness, which is an effective treatment.
Objective
To explore the effectiveness and operation method of the superficial branch of radial artery wrist crease flap for repair of ring tissue defect of the fingers.
Methods
Between June 2013 and March 2016, the superficial branch of radial artery wrist crease flap was used to repair ring finger tissue defect in 20 cases (21 fingers). There were 14 males and 6 females with an average age of 39.3 years (range, 12-61 years). The causes included machine injury in 9 cases, traffic accident injury in 6 cases, heat inury in 2 cases, and avulsed injury in 3 cases. The index finger was involved in 6 cases, middle finger in 6 cases, ring finger in 3 cases, and little finger in 6 cases. Combined injuries included exposure of bone, tendon, vessel, and nerve. The mean time of injury to operation was 3 hours (range, 0.5-5.5 hours) in 17 patients undergoing emergency operation, and was 8.5 days (range, 7-10 days) in 3 patients undergoing selective operation. The superficial palmar branch of the radial artery from the flap was used for bridging proper digital artery. The donor site was directly sutured in 19 cases and was repaired by skin grafting in 1 case.
Results
One case had blood blister at distal flap, which was cured after dressing change; the other flaps survived, and primary healing was obtained. Healing of incision at the donor site healed by first intention. The patients were followed up 6-24 months (mean, 12 months). The appearance, texture, and color of the flaps were satisfactory. The two-point discrimination ranged from 6 to 13 mm (mean, 9 mm) at 6 months after operation. According to the Chinese Medical Association Society of hand surgery of thumb and finger reconstruction function evaluation standard, the results were excellent in 13 cases, good in 4 cases, and fair in 3 cases; the excellent and good rate was 85%.
Conclusion
The superficial branch of radial artery wrist crease flap is an ideal choice for the repair of ring tissue defect of the fingers.
Objective
To summarize the research progress of the artificial wrist joint prosthesis.
Methods
Domestic and abroad literature concerning artificial wrist joint prosthesis was reviewed and analyzed thoroughly.
Results
Artificial wrist joint prosthesis has been developed to the 4th generation. The artificial wrist joint arthroplasty has advantages of pain relief and functional improvement and can achieve ideal short-term effectiveness. But there are some problems, such as loosening, subsidence, fracture, and dislocation of prosthesis. The long-term effectiveness of the 3rd and 4th generation prosthesis still need to be followed up.
Conclusion
The biomechanics of wrist joint is extremely complicated, which results in less application and slow development of artificial wrist joint prosthesis. Early-term effectiveness of artificial wrist joint arthroplasty is basically satisfactory, but there are still some long-term complications. So the artificial wrist joint prosthesis remains to be developed.
Objective To report the clinical experience of using Ilizarov wrist joint distraction technique in the treatment of a case of rheumatoid arthritis of the wrist. Methods In January 2019, a 49-year-old female patient with rheumatoid arthritis of the left wrist, complicated by ulnar impaction syndrome, was admitted for treatment. Preoperatively, the active range of motion of the left wrist was as follows: extension 0°-flexion 0°, pronation 65°-supination 35°, and grip strength of 4.0 kg. The visual analogue scale (VAS) score was 9, and the Cooney wrist function score was 15, indicating poor function. As conservative treatment failed to achieve symptom relief, Ilizarov wrist joint distraction surgery was performed. Postoperatively, joint distraction was applied at 2 mm increments on postoperative days 2 and 7, in 4 separate sessions. Results Postoperative X-ray film examination at 7 days revealed a distraction of 3.6 mm in the affected wrist joint compared to the contralateral side. The external fixator was removed 2.5 months postoperatively. At 22 months postoperatively, X-ray film and MRI examinations revealed that the joint space of the left wrist had returned to near-normal, with significant reduction in joint effusion and synovial proliferation. The active range of motion of the left wrist improved to extension 15°- flexion 30°, pronation 90°-supination 90°, with a grip strength of 18.0 kg. The wrist pain VAS score decreased to 0, and the Cooney wrist function score improved to 90, indicating excellent function. At 50 months postoperatively, follow-up X-ray film, MRI, and functional assessments showed the results similar to those at 22 months. Conclusion Ilizarov wrist joint distraction may be a viable treatment option for rheumatoid arthritis of the wrist.
OBJECTIVE To explore the pathogenic mechanism of intrinsic muscle contracture after replantation of severed palm or wrist, and put forward the prevention and treatment methods. METHODS From 1985 to 1997, 48 cases were received replantation of severed palm or wrist, among them, 9 cases with thumb adductor contracture and 6 cases with intrinsic muscle contracture were occurred in different degree. Two cases with mild thumb adductor contracture were received conservative treatment, and 7 cases with moderate thumb adductor contracture and 6 cases with intrinsic muscle contracture were received operative treatment. The pathogenic mechanism, clinical results, and prevention methods were studied in those 15 cases. RESULTS The postoperative function recovery was better in 4 cases, moderate in 5 cases with thumb adductor contracture, and better in 3 cases, moderate in 1 case with intrinsic muscle contracture, and moderate in 1 case, poor in 1 case with intrinsic muscle contracture of cord-like induration. Followed up 1 to 10 years, no recurrence was observed in all of 15 cases. The incidence and degree of thumb adductor contracture and intrinsic muscle contracture were closely related to the ischemia time of replanting graft. CONCLUSION Prevention of thumb adductor contracture and intrinsic muscle contracture is most important in severed palm or wrist replantation. When the ischemia time of replanting graft is longer than 12 hours, the effective decompression in myofascial compartment is performed in time to reach satisfactory result.
