  • TREATMENT OF MALLET FINGER ACCOMPANIED BY AVULSIONAL FRACTURE WITH ISHIGURO METHOD

    Objective To evaluate the clinical results of mallet finger accompanied by avulsional fracture treated with Ishiguro method. Methods Twenty-seven patients suffering from mallet finger accompanied by avulsional fracture weretreated with Ishiguro method or its modified method. During the operation, a blocking pin was inserted percutaneously with DIP flexed, then the DIP was fixed at a position of full extension with another Kirschner wire. When the fracture fragment was big with rotation displacement, a third Kirschner wire could be used to correct the displacement and fix fracture. Results The patients were followed up 2 months to 6 years and 6 months with an average of 9.3 months postoperatively. Andthe clinical results were evaluated with the modified Crawford’s criteria, including DIP pain, range of motion and pinch power. The rate of bone union was 100%. The results were excellent in 7 patients, good in 11 patients, moderate in 8 patients and poor in 1 patient. After operation, the range of flexion was 54.19°±14.45° , while the range of extension was -4.96°±9.27°. The X-ray sign of slight osteoarthritis could be seen in one patient. [WTHZ]Conclusion Ishiguro method is simple, effective and less invasive. It is suitable for treatment of mallet finger accompanied by avulsional fracture.

  • Clinical classification and treatment experience of wrist gouty arthritis

    ObjectiveTo explore the clinical characteristics, clinical classification, and treatment of wrist gouty arthritis. Methods The clinical data of 24 patients with wrist gouty arthritis and complete follow-up between April 2011 and August 2020 were retrospectively analyzed. There were 21 males and 3 females; the first onset age was 21-72 years, with a median age of 50 years. There were 15 cases of simple wrist joint disease, and 9 cases of other joints (hand, knee, ankle, metatarsophalangeal joint) involvement; 19 cases of wrist joint as the first site. Except for 1 patient with a medical history of 21 years, the time from onset to diagnosis in the remaining 23 patients was 7 days to 9 years, with a median time of 2 months. According to the clinical manifestations, imaging manifestations, lesion range, and intraoperative wrist arthroscopy manifestations of wrist gouty arthritis, they were classified into 5 types from mild to severe. Among the 24 patients, 13 were type Ⅰ, 2 were type ⅡA, 3 were type ⅡB, 2 were type ⅢA, 3 were type Ⅳ, and 1 was type Ⅴ. The time from first onset to diagnosis for type Ⅰ and type Ⅱ patients was (12.7±40.1) months, and for type Ⅲ-Ⅴ patients was (152.0± 88.5) months, the difference was significant (t=−4.355, P=0.001). Thirteen patients with type Ⅰ received conservative treatment (including diet, exercise, lifestyle intervention, and medication), and 11 patients with type Ⅱ-Ⅴ received surgical treatment (including 1 case of arthroscopic synovial membrane and gout crystal clearing, 1 case of ligament repair, 5 cases of lesion debridement/artificial bone grafting and filling, 3 cases of wrist fusion, and 1 case of tophicectomy). Before and after treatment, the visual analogue scale (VAS) score was used to evaluate the improvement of wrist joint pain; and the range of motion of the wrist joint (including palmar flexion, dorsal extension, radial deviation, and ulnar deviation) was evaluated. ResultsThirteen conservatively treated patients were followed up 10 months to9 years, with an average of 2.2 years. The VAS scores before treatment and at last follow-up were 6.8±0.7 and 2.9±0.9, respectively, and the difference was significant (t=12.309, P=0.000). During follow-up, there was no wrist bone and wrist joint damage; wrist joint range of motion basically reached normal. At last follow-up, the wrist joint palmar flexion, dorsal extension, radial deviation, and ulnar deviation significantly improved when compared with the values before treatment (P<0.05). Eleven surgically treated patients were followed up 5 months to 9 years, with an average of 4.9 years. The swelling and pain of all patients fully relieved, and the VAS scores were 7.3±0.8 before operation, 2.7±0.6 at 1 month after operation, and 2.5±0.6 at last follow-up, which significantly improved after operation (P<0.05); there was no significant difference between 1 month after operation and last follow-up (P>0.05). Excluded 3 patients who underwent wrist fusion, the other 8 patients had significantly improved wrist joint palmar flexion, dorsal extension, radial deviation, and ulnar deviation at last follow-up (P<0.05). The patient’s subjective satisfaction with the surgical results reached 100%. Conclusion A missed diagnosis or misdiagnosis of wrist gouty arthritis will greatly damage the wrist stability and functions. Early and proper interventions can effectively retard the progress of the disease. For the late-stage cases, a staged surgical protocol is recommended.

  • PERCUTANEOUS RETROGRADE CANNULATED SCREW FIXATION OF ACUTE STABLE SCAPHOID WAIST FRACTURE BY A TRANSTRAPEZIAL APPROACH

    Objective To explore the technique and effectiveness of percutaneous retrograde cannulated screw fixation for acute stable scaphoid waist fracture by a transtrapezial approach. Methods Between May 2010 and April 2012, 23 patients with acute stable scaphoid waist fracture were treated with percutaneous retrograde cannulated screw fixation by a transtrapezial approach. There were 18 males and 5 females, aged 21-54 years with an average of 32 years. All fractures were caused by supporting with hands after falling. The locations were the left side in 10 cases and the right side in 13 cases. The major symptoms included the wrist swelling, tenderness at the anatomic snuff box, and grip weakness. Two cases were accompanied by distal radius fractures. The time between injury and operation ranged from 1 to 5 days with an average of 3 days. Results All incisions healed by first intention. All the cases were followed up 4-26 months with an average of 10 months. All fractures healed 6-12 weeks postoperatively with an average of 8.2 weeks. The patients resumed normal life and work at 4-6 weeks and at 2-4 months after operation, respectively. At last follow-up, all the wrists were free from the pain and the tenderness. The postoperative grip power ranged from 30 to 51 kg (mean, 37 kg). The active flexion-extension range of motion was 140-165° with an average of 153.7°. All patients were satisfied with the results of treatment. Conclusion Percutaneous retrograde cannulated screw fixation by a transtrapezial approach is a simple, safe, and reliable method to treat acute stable scaphoid waist fracture. By this approach, it is easier to place the screws into the center of the long axis of scaphoid.

  • IMMUNOHISTOCHEMISTRY STUDY OF CALCITONIN GENERELATED PEPTIDE AND SUBSTANCE P LEVELS BETWEEN END-TO-END AND END-TO-SIDE NEURORRHAPHY

    Objective To explore the changes of calcitonin gene-related peptide (CGRP) and substance P (SP) levels after end-toend and end-to-side neurorrhaphy. Methods Twenty female Wistar rats were divided into 4 experimental groups and control group. In the experimental groups, common peroneal nerves were transected on both sides. End-to-side coaptation was performed on the left, while end-to-end coaptation on the right. After 1, 2, 4 and 27 weeks, the rats were sacrificed, and immunoreactivities of CGRP and SP in suture sites, lumbar spine and dorsal root ganglia(DRGs) were evaluated respectively. Results The expression ofCGRP and SP decreased in dorsal horn and DRGs within 1 week postoperatively. After 4 -27 weeks, CGRP and SP in dorsal horn could return to almost normal level, but they had little recovery in DRGs. Although the trend of change between end-to-end and end-to-side was coincident, in most experimental groups, thereexisted differences in the dorsal horn between end-to-end and end-to-side. The sciatic nerve stained by acetylcholinesterase, SP, CGRP and PGP 9.5 showed that the fibers could pass through the suture site of either end-to-end or end-to-side. Conclusion Nerve regeneration can be achieved by end-to-side neurorrhaphy, andthe mechanism of sensory nerve recovery of these two methods is similar. But the recovery in end-to-side coaptation is insufficient to some degree.

  • Diagnosis and treatment of crush syndrome of chest and arm

    ObjectiveTo investigate pathogenesis, diagnosis, and treatment of crush syndrome of chest and arm.MethodsBetween January 2010 and January 2015, 5 cases of crush syndrome of chest and arm caused by pressing oneself in a coma after CO poisoning or alcoholic intoxication were treated. There were 4 males and 1 female with an average age of 36.7 years (range, 28-46 years). Two patients involved left upper limb and chest, while the other three patients involved right upper limb and chest. The crushed time ranged from 4 to 12 hours (mean, 7 hours). All 5 cases received emergency decompression and vacuum sealing drainage (VSD). After surgery, the patients were transferred to Intensive Care Unit to receive continuous renal replacement therapy (CRRT). The wounds were repaired with skin grafts after the patients’ condition were stable.ResultsThe hospitalization time was 26-48 days (mean, 33 days). Necrosis of the skin graft occurred in 1 case, which cured after debridement and skin graft again. The skin graft survived in the other cases and the wounds healed by first intension. Five patients were followed up 12-18 months (mean, 15 months). At last follow-up, the results were excellent in all 5 cases according to the assessment criteria proposed by GU Yudong. The patients got full recovery of their upper limb activities and sensation. All the patients returned to the normal life and work.ConclusionCO poisoning, drunkenness, and pressing oneself together will lead the crush syndrome to severe and rapid progress. The key of the treatment is a comprehensive therapy including a thorough and rapid tension reduction to save the limb function, CRRT, and correction of anemia and electrolyte imbalance.

  • ANATOMICAL AND BIOMECHANICAL RESEARCH OF DORSAL WRIST INTEROSSEOUS LIGAMENTS

    Objective To explore the anatomical features of some major dorsal wrist interosseous l igaments, and to measure their biomechanical properties to screen a suitable donor site for the repair of scapholunate dorsal l igament. Methods Sixteen wrist joints from 8 frozen fresh male adult cadavers were selected, whose age was 20-38 years and whose height was 165-178 cm. There were no injuries to their wrists. The follow l igaments were observed and measured for the interosseous l igaments: volar and dorsal scapholunate l igaments (SL-v, SL-d), lunotriquetral dorsal l igament (LT), trapezoidcapitate dorsal l igament (TC), capitohamate l igament (CH) and the 2nd-4th carpometacarpal l igaments (CMC-2-4). The bone-l igament-bone samples of the above l igaments were prepared for further biomechanical measurements. Ligament extension testing was performed for each bone-l igament-bone sample on a material testing system. The broken load and length were measured and statistically analyzed. Results The SL and the LT were both “C” shape, attaching to the volar, proximal and dorsal joint surface. The TC and CH l igaments were mainly transverse fibers, which connected with each other at the dorsal side of capitate. The CMC-2-4 l igaments were obl iquitous fibers. Within these wrist interosseous l igaments, the SL-v and CMC-4 were relatively long. The l igament length differences were significant between SL-v and TC and between CMC-4 and TC (P lt; 0.05). TC and CMC-2 were fairly thick. But there was no significant difference among the l igaments (P gt; 0.05). SL-d had the highest broken load of (73.6 ± 9.6) N. The broken load differences were all significant between SL-d and other l igaments (P lt; 0.05). SL-v had largest broken length of (5.24 ± 1.65) mm. The broken length differences were all significant between SL-v and other l igaments (P lt; 0.05). Conclusion The anatomical structures and biomechanical features of the wrist interosseous l igaments were closely related with their physiological functions. CMC-2 and CH are both suitable to be used for the repair of scapholunate dorsal l igament.
