Bifid median nerve as a determinant of carpal tunnel syndrome recurrence after endoscopic procedures. A case report

A number of complications have been associated with endoscopic technique in treating carpal tunnel syndrome (CTS). We observed a female patient who had previously undergone endoscopic surgery for CTS. Shortly after surgery, this patient complained of pain, numbness and strength deficiency, as severe as it was before the operation. A new, open, surgical procedure was performed. During this second-look surgery, we found a bifid median nerve, which divided into two branches at the second third of the forearm, proximal to the flexor retinaculum. We strongly suggest a careful exploration of the median nerve in the carpal tunnel. Moreover, we believe that an extensive preoperative assessment of median nerve morphology and function is mandatory prior to endoscopic approach in treating CTS

De Quervain disease in volleyball players

BACKGROUND: Chronic inflammatory tendon diseases in athletes are frequent, and they often result from modifications in normal kinematics of a tendon associated with a patient's anatomical determinants. De Quervain stenosing tenosynovitis is an inflammatory disease of tendons of the first dorsal compartment of the wrist. There is no literature about this disease concerning professional volleyball players. HYPOTHESIS: Limited, multiple trauma on the dorsal radial portion of the wrist, associated with long training times, can be involved in the pathogenetic process of de Quervain disease in professional volleyball players. STUDY DESIGN: Case series; Level of evidence, 4. MATERIALS AND METHODS: The authors studied 45 consecutively enrolled volleyball players (27 professional, 18 nonprofessional) satisfying clinical criteria for the diagnosis of de Quervain stenosing tenosynovitis. All patients were evaluated by questionnaire and physical examination. They were divided into group A (mild) and group B (severe) based on the severity of the symptoms and physical findings; they were followed for a mean of 37 months. RESULTS: Total training quantity (mean weekly training time multiplied by mean sports activity duration) in group A was 74, whereas it was 155 in group B (P < .01). No neuropathies were found in group A, whereas they were found in 3 patients in group B. Fifty percent of surgical patients had a longitudinal fibrous septum, whereas 54% showed multiple tendon sheaths making up the abductor pollicis longus tendon. CONCLUSIONS: This study shows that increased training time and consequent microtrauma associated with professional volleyball activity can increase the likelihood of de Quervain diseas

Mini-open blind procedure versus limited open technique for carpal tunnel release: A 30-month follow-up study

Purpose: To evaluate prospectively the safety and effectiveness of a mini-open blind technique for carpal tunnel release (group A) when compared with a limited open technique (group B). Methods: From November 1999 to May 2001 (mean follow-up period, 30 mo) we performed 222 carpal tunnel release procedures on 185 consecutive patients. All patients were affected by mild to moderate median nerve compression. Patients in group A (82 patients, 99 procedures) had a short transverse incision at the wrist (length, 2 cm). We used a manual surgical instrument that helps in blindly dividing the flexor retinaculum because it-has an integrated light source. The light makes it possible to locate precisely the tool blade by transillumination. Patients in group B (103 patients, 123 procedures) had a limited longitudinal incision (length, 3-4 cm), The preoperative and postoperative patient statuses were evaluated with an Italian modified version of the Boston Carpal Tunnel questionnaire with a mean of 30 months' follow-up after surgery (range, 24-39 mo). Results: Group A patients showed better results than group B patients in all of the sections of the Italian modified version of the Boston Carpal Tunnel questionnaire at a mean follow-up period of 19 months, whereas after a mean of 30 months of follow-up evaluation the differences between groups A and B tended to decrease. Disease recurred in 7 group B patients, whereas only 1 patient in group A experienced symptom recurrence at the latest office evaluation. Conclusions: The blind mini-invasive technique has been shown to be as safe as traditional techniques but the recovery period is significantly shortened. With the technique we described a low recurrence rate was observed. All patients in group A reported great reduction in preoperative pain and numbness

Acute traumatic instability of the coccyx: results in 28 consecutive coccygectomies

Coccygeal instability includes hypermobility, subluxation and fracture-dislocation. Surgical resection is still controversial, with intractable post-traumatic coccygodynia being an indication to surgery. From 2001 to 2010, we enrolled 31 patients with post-traumatic coccygodynia (19 females, 12 males; mean age 31 years, range 21-47). Conservative treatment failed in 28 patients, who underwent surgical resection of the coccyx. Twenty-one were total, while seven were partial coccygectomies. At follow-up (mean 33 months; range 24-70), clinical outcomes evaluation included measurement of complications rate, pain relief and satisfaction degree. Nineteen patients experienced complete pain relief, while two had incomplete, and four had no relief. Partial coccygectomies were associated with poor results. Twenty-one patients were satisfied, whilst four were not. Coccygectomy is the treatment of choice for post-traumatic instability. Patients' selection allowed excellent or good results. This study favors a more aggressive approach including total resection of the coccyx.INTRODUCTION: Coccygeal instability includes hypermobility, subluxation and fracture-dislocation.

Neurological L5 burst fracture: posterior decompression and lordotic fixation as treatment of choice.

Purpose: We report our experience and literature review concerning surgical treatment of neurological burst fractures of the fifth lumbar vertebra. Materials and methods: Nineteen patients with L5 neurological burst fractures were consecutively enrolled; 6 patients had complete motor deficits, and 12 had sphincter dysfunction. We performed 18 posterior and one combined approaches. To avoid kyphosis, posterior internal fixation was achieved by positioning patients on the operating table with hips and knees fully extended. At the latest follow-up (mean 22 months, range 10-66), neurological recovery, canal remodeling and L4-S1 angle were evaluated. Results: Vertebral body replacement was difficult, which therefore resulted in an oblique position of the cage. Vertebral bodies still remained deformed, even though fixation allowed for an acceptable profile (22°, range 20-35). We observed three cases of paralysis, five complete, and three incomplete recoveries. In the remaining eight patients, sphincter impairment was the only finding. In 15 patients, pain was absent or occasional; in four individuals, it was continuous but not invalidating. Remodeling was visible by X-ray and/or CT, without significant secondary stenosis. Conclusions: The L5 burst fractures are rare and mostly due to axial compression. Cauda and/or nerve root injuries are absolute indications for surgery. If an anterior approach is technically difficult, laminectomy can allow for decompression, and it can be easily combined with transpedicular screw fixation. Posterior instrumented fusion, also performed with the aim to restore sagittal profile, when associated with an accurate spinal canal exploration and decompression, may be looked at as an optimal treatment for neurological L5 burst fractures. © Springer-Verlag 2012
