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 investigate the efficacy of a modified intermittent horizontal mattress suture technique in arterial anastomosis with intimal dissection during free flap transplantation.Methods:A retrospective analysis was conducted on patients with limb wounds who underwent free flap transplantation with the modified intermittent horizontal mattress suture technique at the First People’s Hospital of Pingyuan County from September 2016 to November 2023. After debridement, free flap transplantation was performed. Under microscopic examination, recipient arteries with intimal dissection were identified, and proximal trimming failed to resolve the delamination. The modified intermittent horizontal mattress suture technique was applied to anastomose the dissected recipient arteries to donor arteries, while veins were conventionally horizontal mattress sutured. Postoperative flap viability, complications, and patient satisfaction were evaluated.Results:Fourteen patients were enrolled, including 8 males and 6 females, aged (51±14) years old (range: 18-71 years). Injuries involved the hand (5 cases) and foot (9 cases), with wound sizes ranging from 7 cm×8 cm to 22 cm×18 cm. Flaps included anterolateral thigh perforator flaps (11 cases) and groin flaps (3 cases), sized 8 cm×9 cm to 24 cm×20 cm. Seven patients had intimal dissection of the dorsalis pedis artery, with anastomoses performed to the descending branch of the lateral circumflex femoral artery (LCFA) in 5 cases, and to the superficial circumflex iliac artery in 2 cases. Intimal dissection of the medial plantar artery was identified in 2 cases, both of which were anastomosed to the descending branch of LCFA. And 5 cases had intimal dissection of the radial artery, with anastomoses performed to the LCFA in 3 cases, to the transverse branch of LCFA in one case, and to the superficial circumflex iliac artery in one case. The patients were followed up for (11.6±7.6) months (range: 3-30 months) after surgery. Eleven flaps survived completely, with partial flap margin necrosis in one case, in another case necrosis of one-third of the flap because of arterial insufficiency, both cases healed with dressing changes. The third patient resumed smoking and subsequently fell from the bed, resulting in necrosis of two-thirds of the flap five days post-discharge (12 days postoperatively). After debridement of the necrotic part of the flap, a split-thickness skin graft was applied for repair. Thirteen flaps exhibited no ulceration, with satisfactory texture and appearance, these patients expressed satisfaction. One patient with skin graft infection achieved scar healing.Conclusion:The modified intermittent horizontal mattress suture technique ensures reliable anastomosis of arteries with intimal dissection in free flap surgery, improving success rates and yielding favorable outcomes with high patient satisfaction.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.

Objective:To investigate the clinical outcomes of homodigital reversed dorsal digital artery island flap innervated by the dorsal digital nerve to repair degloving injury of distal thumb.Methods:From July 2016 to June 2019, a total of 15 cases (15 thumbs) with degloving injury of distal part were admitted to the Department of Hand Surgery, the Second Hospital of Tangshan. Nine males and six females were involved, with an average age of 49 years (range, 41 to 69 years). There were twist injury in eight cases and crush injury in seven cases, with four cases of distal phalanx fracture. The defect dimensions after debridement ranged from 3.5 cm×1.8 cm to 4.6 cm×2.4 cm, and the dimension of the flaps ranged from 3.8 cm×2.1 cm to 5.0 cm×2.7 cm. All defects were repaired using homodigital reversed dorsal digital artery island flap innervated by the dorsal digital nerve. The survival, appearance and sensory recovery of the flaps and function of the injured fingers were observed at the follow-up after operation.Results:All the flaps survived without wound infection and blood supply disorder. The follow-up times ranged from 9 to 22 months (mean, 16 months). There was satisfactory appearance of the flaps with similar color and texture to the surrounding tissue. Fracture healing ranged from 4 to 6 weeks. At final follow-up, the values of static 2-PD test of the flaps ranged from 5 to 10 mm (mean, 7.8 mm). The results of range of motion of injured thumb joints were excellent in nine cases and good in five cases. There was slight linear scar left at the donor area of dorsal thumb.Conclusions:The innervated reversed dorsal digital artery island flap has a simple procedure and minimal donor-site cost, which is especially suitable for elderly patients who refuse to free toe transfers.

The dorsal branch of digital artery pedicled flaps with dorsal branch of the proper digital nerve and dorsal digital nerve were designed in the proximal dorsum of the affected fingers to repair dorsal wounds in the distal dorsum of the affected fingers, and the sizes of the flaps ranged from 1.6 cm×1.5 cm to 2.6 cm×2.4 cm. The V-Y advancement flaps in the palmar side of the affected fingers were designed to repair palmar wounds in the distal segment of the affected fingers, and the sizes of the flaps ranged from 0.8 cm×0.6 cm to 2.0 cm×1.5 cm. The reverse dorsal metacarpal recurrent artery pedicled island flaps were used to repair the soft tissue defects in the donor sites of proximal dorsum, the sizes of the flaps ranged from 1.8 cm×1.7 cm to 2.8 cm×2.6 cm, and the donor sites of the flaps in back of hand were sutured directly. The survivals after the operation and the blood supply and appearance during follow-up of the three flaps were observed. At the final follow-up, the static two-point discrimination distance of the three flaps was measured, the satisfaction degree of patients for the appearance of hand was evaluated based on Michigan Hand Function Questionnaire, and the total active range of motion of the injured finger joints was assessed by the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association.Results:All the flaps survived after operation. Tension blisters appeared on the surface of one dorsal branch of digital artery pedicled flap, and the wound healed after removing the stitch at the pedicle and changing dressings. During follow-up of 6-20 months, with an average of 12 months, the three kinds of flaps had good appearance, soft texture, and similar color with surrounding tissue, and with only linear scars in donor sites of the dorsal hand. At the final follow-up, the static two-point discrimination distances of V-Y advancement flaps, dorsal branch of digital artery pedicled flaps, and reverse dorsal metacarpal recurrent artery pedicled island flaps were 4-7 mm, 5-10 mm, and 8-15 mm, respectively. Sixteen patients were strongly satisfied with the appearance of hand, and the remaining five patients were satisfied with the appearance of hand. The total active range of motion of the injured finger joints was evaluated as excellent in 17 cases, good in 4 cases.Conclusions:The operation is simple and reliable for dorsal branch of digital artery pedicled flap combined with V-Y advancement flap to repair the degloving injury of fingertip, and reverse dorsal metacarpal recurrent artery pedicled island flaps to repair the soft tissue defects in the donor sites of the proximal dorsum, and the appearance and function of the affected fingers recover well, with minimal injury.

Objective:To investigate the clinical effects of ulnar artery perforator chain flaps in repairing wounds on distal forearm or wrist with vascular anastomosis.Methods:The retrospective observational study method was used. From March 2015 to July 2019, a total of 11 serious trauma patients on distal forearm or wrist with vascular injury were admitted to the Second Hospital of Tangshan, including 8 male patients and 3 female patients, aged from 25 to 62 years, with an average age of 45 years. Vascular anastomosis and tendon repair were performed in all patients, and fracture reduction and fixation were conducted in 9 patients, of which 8 patients underwent external fixation of radius. The residual wounds were located in palmar distal forearm in 5 patients, palmar wrist in 4 patients, dorsal distal forearm in 1 patient, and dorsal wrist in 1 patient, with wound sizes ranged from 4.5 cm×3.0 cm to 10.0 cm×6.0 cm after the last debridement. The wounds were repaired with ulnar artery perforator chain flaps, with the flap sizes ranged from 5.2 cm×3.5 cm to 11.0 cm×7.0 cm. The wound in flap donor site of 1 patient was sutured directly, the wounds in flap donor sites of the other 10 patients were repaired with free skin grafts from ipsilateral thigh after being sutured partially, and the sizes of free skin grafts ranged from 4.0 cm×2.0 cm to 8.5 cm×5.0 cm. The survivals of flaps, skin grafts, and injured limbs after operation were observed. The appearances of the flaps and donor sites of flaps were observed during follow-up. At the final follow-up, the static two-point discrimination distances of the flaps were measured, and the satisfaction degrees of patients for the appearances of injured limbs were evaluated based on Michigan Hand Function Questionnaire.Results:All flaps, skin grafts, and injured limbs survived after operation, without wound infection and blister formation. All patients were followed up for 8 to 26 months, the appearances of the flaps were good and not bloated, with similar color, texture, and thickness to the surrounding skin. The donor sites of flaps repaired with skin grafts were smooth, with circle scar at the edges. At the final follow-up, the static two-point discrimination distances of the flaps was 10-15 mm; 7 patients were strongly satisfied with the appearances of the injured limbs, and the remaining 4 patients were satisfied with the appearances of flaps.Conclusions:The ulnar artery perforator chain flap has constant vascular anatomy and reliable blood supply, with simple operation, which provides a good treatment method for repairing wounds on distal forearm or wrist with vascular anastomosis. It is especially suitable for the patients with radius fracture fixed by external fixator.

Objective:To investigate the clinical effects of neurocutaneous vascular flap innervated by terminal branch of lateral antebrachial cutaneous nerve in repairing finger tip or finger pulp wounds of the thumb.Methods:A retrospective observational study was conducted. From February 2016 to April 2019, a total of 21 patients (21 fingers) with finger tip or finger pulp wounds of the thumbs met the inclusion criteria and were admitted to the Second Hospital of Tangshan, including 13 males and 8 females, aged 21 to 65 years, with the defects located at the finger tips of 14 patients and the finger pulps of 7 patients, and all having exposed bones and/or tendons. The wound sizes of patients in this group after debridement ranged from 2.0 cm×1.5 cm to 4.0 cm×2.7 cm. All the wounds were repaired with the neurocutaneous vascular flap innervated by terminal branch of lateral antebrachial cutaneous nerve, with the flap sizes ranging from 2.3 cm×1.8 cm to 4.3 cm×3.0 cm. In surgery, the terminal branch of lateral antebrachial cutaneous nerve carried by the flaps was anastomosed with the end of the proper digital nerve of the wounds. The donor sites of flaps were sutured directly. The survival of flaps and healing of wounds in donor sites after operation were observed. The appearance of flaps and donor sites were observed during follow-up. At the final follow-up, the static two-point discrimination distances of the flaps were measured, and the degree of satisfaction of patients for the appearances of injured hands were evaluated based on Michigan Hand Function Questionnaire. The total action motion (TAM) of the injured and contralateral thumbs and the angle of thumb web of the injured and contralateral hands were measured. Data were statistically analyzed with paired sample t test. Results:All the flaps of the 21 patients survived with good blood supply and no infection. The wounds at the donor sites were all healed. All the patients were followed up, with the time ranging from 8 to 22 months. The appearances of flaps were good with their color and texture similar to the surrounding tissue. There was no pain in the finger tip or finger pulp, nor any ectopic sensation in flaps. There was only some linear scar left at the radial side of thumb. At the final follow-up, the static two-point discrimination distances of the flaps of the patients were 6 to 11 mm; 18 patients were very satisfied and 3 patients were satisfied with the overall appearance of the injured hand. The TAM of injured thumbs and the angle of thumb web of the injured hands of the patients were respectively (140±5)o and (94±9)°, which were similar to (141±5)o of the thumbs and (95±9)° of hands in the contralateral side, respectively ( t=-2.024, -1.142, P>0.05). Conclusions:The neurocutaneous vascular flap innervated by terminal branch of lateral antebrachial cutaneous nerve has constant anatomy and is easy to perform. It can repair the finger tip or finger pulp wounds of the thumb achieving good appearance and function recovery. It provides a good option for repair of finger tip or finger pulp wounds of the thumb and is especially suitable for emergency application.
