Objective To summarize the experience of treating old metatarsal fractures with surgery methods of miniplate internal fixation and autogenous il iac bone. Methods Between May 2009 and July 2010, 7 patients with old metatarsal fractures were treated surgically, including 5 multi-metatarsal fractures and 2 single metatarsal fractures. There were 5 males and 2 females aged from 25 to 43 years (mean, 33 years). The time from fracture to operation was 4-12 weeks. The X-rayfilms showed that a small amount of callus formed at both broken ends with shortening, angulation, or rotation displacement. The surgical treatments included open reduction, internal fixation by miniplate, and autogenous il iac bone graft (1.5-2.5 cm3). The external plaster fixation was used in all patients for 4 to 6 weeks postoperatively (mean, 5 weeks). Results All incisions healed by first intention. The 7 patients were followed up 8-18 months (mean, 13.5 months). The cl inical fracture heal ing time was 6 to 12 weeks postoperatively (mean, 8.4 weeks). No pain of planta pedis occurred while standing and walking. The American Orthopaedic Foot and Ankle Society (AOFAS) mesopedes and propodium score was 75-96 (mean, 86.4). Conclusion It has the advantages of rel iable internal fixation, high fracture heal ing rate, less compl ications to treat old metatarsal fractures with surgery methods of miniplate internal fixation and autogenous il iac bone graft, so it is an effective treatment method.
Objective To analyze the early effectiveness of unilateral biportal endoscopic discectomy (UBED) combined with annulus fibrosus suture in the treatment of lumbar disc herniation (LDH). Methods The clinical data of 19 patients with LDH treated with UBED and annulus fibrosus suture between October 2020 and October 2021 were retrospectively analyzed. There were 12 males and 7 females with an average age of 39.1 years (range, 26-59 years). The operative segment was L4, 5 in 13 cases, and L5, S1 in 6 cases. The mean disease duration was 6.7 months (range, 3-15 months). Preoperative neurological examination showed that muscle strength, sensation, and tendon reflex weakened or disappeared in varying degrees. Single annulus fibrosus suture (14 cases) or anchor assisted annulus fibrosus suture (5 cases) was selected according to the location of annulus fibrosus tears. Visual analogue scale (VAS) score was used to assess the low back and leg pain before operation and at 3 days, 3 months, and 6 months after operation. Oswestry disability index (ODI) was used to evaluate the function recovery of lumbar spine before operation and at 3 days, 3 months, and 6 months after operation. At 3 days and 3 months after operation, MRI was used to examine the removal of nucleus pulposus and decompression of nerve root. MacNab criteria was used to evaluate the effectiveness at 6 months after operation and the recovery of nerve root function was recorded. Results All operations were successfully completed with a mean operation time of 52.7 minutes (range, 40-75 minutes). There was no complication such as nerve injury, spinal cord hypertension syndrome, or dural sac tear during operation, and no complication such as infection, aggravation of nerve damage, or cerebrospinal fluid leakage after operation. All the patients were followed up 6-10 months (mean, 8.2 months). Postoperative MRI showed that the herniated disc was completely removed and nerve roots were fully decompressed. During the follow-up, there was no recurrence of disc herniation. The VAS scores of low back pain and leg pain and ODI at each time point after operation significantly improved when compared with those before operation, and those at 6 months after operation further improved than those at 3 days and 3 months after operation, all showing significant differences (P<0.05). At 6 months after operation, MacNab standard was used to evaluate the effectiveness, and the results were excellent in 14 cases, good in 4 cases, and fair in 1 case, with an excellent and good rate of 94.7%. Neurological examination showed that the sensation and muscle strength of the affected nerve root innervated area recovered significantly when compared with those before operation (P<0.05); the recovery of tendon reflex was not obvious, showing no significant difference when compared with that before operation (P>0.05). ConclusionUBED combined with annulus fibrosus suture is a safe and effective technique for LDH and early effectiveness is satisfactory.
