OBJECTIVE: To evaluate the effectiveness of Poster Fusion Cage combined with xenogeneic bone graft augmentation for bone defect management in distal radius fractures. METHODS: A retrospective analysis was conducted on 20 patients with bone defects complicating distal radius fractures who met the selection criteria and were treated between June 2022 and June 2024. The cohort comprised 2 males and 18 females, aged 54-87 years (mean, 63.3 years). Etiologies included falls in 17 cases, traffic accidents in 2 cases, and crush injury in 1 case. According to AO classification, there were 5 cases of type A, 8 cases of type B, and 7 cases of type C. The interval from injury to operation ranged from 2 to 10 days (mean, 5.8 days). All patients underwent volar plate fixation augmented with Poster Fusion Cage and demineralized xenogeneic bone matrix grafting. The operation time, intraoperative blood loss, fracture healing time, and postoperative complications were recorded. Radiographic parameters, including radial height, volar tilt, and ulnar deviation, were measured on standardized X-ray films obtained immediately postoperatively and at last follow-up, and whether secondary reduction loss occurred was judged. At last follow-up, wrist range of motion (extension, flexion, radial deviation, ulnar deviation, pronation, and supination) and grip strength (expressed as a percentage of the contralateral side) were measured. Wrist function was assessed using the Disabilities of the Arm, Shoulder, and Hand (DASH) score and Patient-Rated Wrist Evaluation (PRWE) score. RESULTS: The operation time was 70-200 minutes (mean, 116.4 minutes), and the intraoperative blood loss was 10-80 mL (mean, 36.5 mL). All surgical incisions healed by first intention, with no neurovascular complications documented. All patients were followed up 9-12 months (mean, 11.6 months). All fractures healed normally, with a healing time of 8-14 weeks (mean, 9.95 weeks). No significant difference was observed in radial height, volar tilt, or ulnar deviation between immediate postoperatively and last follow-up ( P>0.05). All fractures achieved satisfactory reduction, with no secondary loss of reduction or implant failure occurring during follow-up. At last follow-up, the range of motion of the affected wrist joint was 60°-65° (mean, 62.5°) in extension, 67°-75° (mean, 71.1°) in flexion, 18°-23° (mean, 20.4°) in radial deviation, 28°-33° (mean, 30.1°) in ulnar deviation, 69°-80° (mean, 74.7°) in pronation, and 69°-82° (mean, 75.6°) in supination. Grip strength recovered to 75%-85% (mean, 80%) of the contralateral side. Functional scores showed a DASH score of 5-15 (mean, 9.4) and PRWE score of 8.0-12.5 (mean, 10.2). CONCLUSION The combination of Poster Fusion Cage and xenogeneic bone graft augmentation provides a safe and effective treatment for bone defects in distal radius fractures.

OBJECTIVE: To investigate the effectiveness of distal radius core decompression in the treatment of chronic wrist pain caused by various etiologies. METHODS: A retrospective analysis was performed for the clinical data of 10 patients with chronic wrist pain treated with distal radial core decompression between January 2018 and December 2021. There were 6 males and 4 females with an average age of 37.4 years (range, 21-55 years). The disease duration ranged from 7 to 72 months, with an average of 26.5 months. Preoperative MRI examination showed that 10 cases had bone marrow edema at the distal radius on the affected side, and 8 cases had bone marrow edema in the carpal bones such as scaphoid and lunate bone. Among them, 3 patients had a history of wrist fracture, and 2 patients had Kienböck diseases (1 case each in stage ⅡB and stage ⅢA). Three cases were combined with triangular fibrocartilage complex (TFCC) type 1A injury. Two cases were combined with osteoarthritis, 1 of them was complicated with severe traumatic arthritis, the wrist arthroscopy showed that the TFCC was completely lost and could not be repaired, and the cartilage of the lunate bone and the ulnar head were severely worn.Visual analogue scale (VAS) score was used to evaluate the relief of wrist pain before operation, at 6 months after operation, and at last follow-up, and the range of motion of the affected wrist in dorsiflexion, palmar flexion, ulnar deviation, and radial deviation was measured. The degree of bone marrow edema was evaluated according to T1WI, T2WI, and STIR sequences of MRI. RESULTS: All the patients were followed up 12-22 months, with an average of 16.4 months. Except for 1 patient who experienced persistent wrist joint pain and limited mobility after operation, the remaining 9 patients showed significant improvement in pain symptoms and wrist joint mobility. The VAS score and range of motion of wrist dorsiflexion, palmar flexion, ulnar deviation, and radial deviation at 6 months after operation and at last follow-up were significantly improved when compared with those before operation, the VAS score and the range of motion of wrist ulnar deviation and radial deviation at last follow-up were further improved when compared with those at 6 months after operation, all showing significant differences ( P<0.05). There was no significant difference in wrist dorsiflexion and palmar flexion between at 6 months after operation and at last follow-up ( P>0.05). Bone marrow edema was improved in 6 patients on MRI at 6 months after operation, and was also improved in other patients at last follow-up. CONCLUSION For chronic wrist pain caused by a variety of causes, distal radius core decompression can directly reduce the pressure of the medullary cavity of the distal radius, improve the blood supply of the corresponding distal structure, significantly alleviate chronic wrist pain, and provide an option for clinical treatment.

OBJECTIVE: The relationship between the distal screws and the wrist articular surface was assessed by the additional lateral oblique fluoroscopic view during the operation, and the dorsal tangential view of the wrist was used to observe whether the distal screw penetrated the dorsal cortex, so as to evaluate the clinical efficacy of the volar locking plate in the treatment of distal radius fractures. METHODS: From January 2020 to June 2021, 45 cases of fresh distal radius fractures were treated using the volar Henry's approach, including 20 males and 25 females, aged from 32 to 75 years old with an average of (52.4±8.1) years old. During the operation, they were divided into 2 groups according to the different intraoperative fluoroscopic views:the control group of 20 cases, treated with standard anteroposterior and lateral fluoroscopic view;25 cases in the observation group, additional lateral oblique fluoroscopic view and dorsal tangential view of the wrist were taken. The wrist joint function score and postoperative complications were evaluated at 6 weeks, 3 and 6 months after operation between two groups. RESULTS: All 45 patients were followed up and the duration ranged from 6 to 14 months, with an average of (10.8±1.7) months, all patients achieved bone union and the incision healed well. The incidence of postoperative complications in the observation group was lower than that in the control group, and the difference was statistically significant (P<0.05). In terms of Gartland-Werley score of wrist joint function, the score of wrist function in the observation group was (4.58±1.31) at 6 weeks, (2.98±0.63) at 3 months and (1.95±0.65) at 6 months post-operatively, which were better than those in the control group (6.32±1.96) at 6 weeks, (3.63±0.76) at 3 months and (2.43±0.73) at 6 months. The difference was statistically significant (P<0.05). In the observation group, 7/25 cases(28%) were found to have screw penetration during the operation by additional lateral oblique and dorsal tangential radiograph fluoroscopic views of wrist. CONCLUSION The addition of lateral oblique and dorsal tangential during the operation could improve the accuracy of distal screw placement, reduce postoperative complications, and achieve early functional exercise.

Radial head excision has always been a safe commonly used surgical procedure with a satisfactory clinical outcome for isolated comminuted radial head fractures. However, diagnosis of elbow instability is still very challenging and often underestimated in routine orthopaedic evaluation. We present the case of a 21-years old female treated with excision after radial head fracture, resulting in elbow instability. The patient underwent revision surgery after four weeks. We believe that ligament reconstruction without radial head substitution is a safe alternative choice for Mason III radial head fractures accompanied by complex ligament lesions.

OBJECTIVETo summarize our experiences in the treatment of type C3 (AO/OTA) distal radius fractures fixed with AO 2.4 mm locking plates combined with percutaneous pinning after manipulative reduction.

METHODSFrom May 2009 to March 2012, 19 patients (2 cases of both sides) with type C3 (AO/OTA) distal radius fractures were treated with volar locking plates combined with percutaneous pinning for distal radius after manipulative reduction. Among the patients, the average age was (45.3 ± 17.4) years old (ranged, 31 to 66 years old). The fracture were complicated with ulnar styloid fracture in 14 wrists and 6 wrists had distal radioulnar joint instability. All the patients had closed fracture and the mean duration was (6.7 ± 3.5) days (4.5 to 9 days). The Henry approach was applied to expose the fracture site. Joint capsule and ligaments were retained for indirect reduction. After indirect reduction, the poking reduction technique was used to correct the residual compression, and congruence of distal ulnar radial joint was verified under fluorscopic guidance. Styloid process was first pinned percutaneously and then AO 2.4 mm volar locking plate was used to support rigid fixation. The fractures complicated with distal radioulnar joint instability and ulnar styloid fracture were treated with forearm plaster support in supination for 6 weeks.

RESULTSNineteen patients (21 wrists) were followed up for an average duration of 10.5 months (ranged, 7 to 17 months). Radiographic bone union of distal radius was achieved in all cases, nonunion of the ulnar styloid occurred in 3 cases, and no distal radioulnar joint instability occurred. Tendon irritation was found in 2 cases and disappeared after the internal fixation was removed. The volar tilt, radial angle, radial length, incongruence of articular surface and distal radioulnar joint were observed at the follow-up. According to Batra and Gupta scoring system, 13 wrists were assessed to have a score of more than 80, 5 wrists 70 to 90, 3 wrists less than 70. Meanwhile, the subjective and objective evaluation was executed,range of motion of wrist, residual deformity and complications were observed. According to Sarmiento's modification of the system of Gartland and Werley, 17 wrists got an excellent result, 3 good and 1 fair.

CONCLUSIONType C3 (AO/OTA) distal radius fractures could be managed with manipulative reduction. Locking plate internal fixation combined with percutaneous pinning can offer enough support for early mobilization and rehabilitation, resulting in a better clinical outcome and satisfactory prognosis.

OBJECTIVETo study therapeutic effects of comprehensive traditional Chinese medicine therapy for preventing postsurgery stiffness after operation for terrible triad of the elbow.

METHODSFrom December 2008 to December 2013,32 patients with elbow triad were randomly divided into two groups: therapy group and control group. There were 17 patients in control group including 12 males and 5 females with a mean age of (41.0 ± 7.1) years old. The patients in control group were received the past procedure therapy. There were 15 patients in therapy group, including 10 males and 5 females with a mean age of (41.3 ± 7.6) years old. The patients in therapy group were received comprehensive traditional Chinese medicine therapy, including passive exercise training at early stage (0 to 2 weeks after operation), transition from passive to active exercise training at middle stage (3 to 4 weeks after operation), and active exercise training at late stage (5 to 12 weeks after operation). Other treatment methods, such as orally taking or externally use of Chinese herbal medicine, manipulation and physiotherapy, were used at all stages. The Mayo Elbow Performance Score, patient satisfaction and complications were evaluated and analyzed.

RESULTSAll the patients were followed up, and the mean duration was 7.5 months. There were no complications such as internal fixation loosing, obvious displacement fracture and heterotopic ossification occurred. The Mayo score and patient satisfaction in therapy group were higher than those in control group (t = 12.78, P = 0.00; χ2 = 8.719, P = 0.003). Seven patients needed reoperation in control group, compared with 1 patient in therapy group (χ2 = 4.626, P = 0.032).

CONCLUSIONThe comprehensive traditional Chinese medicine therapy is effective to prevent postoperative stiffness after operation for terrible triad of the elbow by using different methods at different stages, which is worthy of spread and application.

OBJECTIVETo investigate the internal fixation methods in the two different surgical approach to the unstable distal radius fractures.

METHODSFrom August 2006 to October 2010,47 patients with distal radius fractures were treated with open reduction and plate internal fixation. Among the patients, 21 patients were male and 26 patients were female,ranging in age from 39 to 73 years old. All the patients were divided into two groups: 32 patients were treated with plate fixation at the palm side with palm side incision (group A),including locking plate used in 27 patients and ordinary T shape plate used in 5 patients; 15 patients were treated with dorsal plate fixation (group B), including locking plate used in 7 patients and ordinpry T shape plate used in 8 patients. The postoperative wrist function, X-ray score,complications were compared between the two groups.

RESULTSCompare to preoperative, postoperative volar tilt,ulnar deviation and radial styloid height of both groups improved; and comparison between 1 week after operation and 6 months after operation,volar tilt,ulnar deviation and radial styloid height of both groups had no obvious loss. In group A, 1 patient had tension injury of median nerve, 1 patient had incision infection, 2 patients had adhesion of tendon; and in group B,1 patient had incision swelling and infection, 1 patient had adhesion of tendon,3 patients had stimulation of extensor pollicis longus muscle tendon. The complication occurrence rate of group A is lower than that of group B. The wrist functional assessment: 17 patients got an excellent results, 11 good, 3 poor and 1 bad in group A; and 8 excellent, 4 good, 2 poor and 1 bad in group B. There was no statistically significant difference of wrist function between the two groups.

CONCLUSIONPlate fixation at the palm side for the treatment of unstable distal radius fractures can also achieve a good reduction,and has less complication such as tendon damage than that of dorsal plate fixation.

Although extensor tendon rupture often occurs after volar plating for a distal radius fracture, a flexor tendon rupture is extremely rare. Most reported instances of flexor tendon ruptures after volar plating have involved improper placement of the plate, increased prominence of the distal edge of the plate because of collapse of the fracture site, use of custom-made plates, current steroid use by the patient, or a history of tendon injury. We report a case of delayed rupture of the flexor pollicis longus tendon 40 months after volar plating with a 3.5-mm T-locking compression plate for which the distal edge was located at the transverse ridge level of the distal radius. If symptoms such as tendon irritation occur in this situation, surgeons should consider removing the plate as soon as possible after bony union is achieved.

OBJECTIVETo investigate the effects of open reduction by palm side for the distal radius fracture and T shape plate internal fixation with simultaneous anterior transverse carpal ligament resection for the prevention of delayed carpal tunnel syndrome after operation.

METHODSFrom March 2000 to March 2007, 32 patients (8 males and 24 females, ranging in age from 46 to 66 years) with distal radius fracture were treated with open reduction by palm side and T shape plate internal fixation with simultaneous anterior transverse carpal ligament resection; while 30 patients (7 males and 23 females,ranging in age from 45 to 65 years) only with open reduction by palm side and T shape plate internal fixation. The incidences of delayed carpal tunnel syndrome between the two groups were compared.

RESULTSAmong 32 patients treated with open reduction by palm side and T shape plate internal fixation with anterior transverse carpal ligament resection, 3 patients had delayed carpal tunnel syndrome; while in 30 patients treated with open reduction by palm side and T shape plate internal fixation, 10 patients had delayed carpal tunnel syndrome. There was significant statistically difference (P < 0.05%).

CONCLUSIONSimultaneous anterior transverse carpal ligament resection can effectively prevent the delayed carpal tunnel syndrome occurrence for the distal radius fracture with open reduction by palm side.
