Abstract
Diabetes mellitus is associated with the development of several pathologic conditions of the hand, including carpal tunnel syndrome, Dupuytren disease, trigger digits, and limited joint mobility or cheiroarthropathy. In recent years, across a variety of surgical disciplines, increased emphasis has been placed on the impact of diabetes on treatment outcomes. This review provides an overview of the current literature regarding the effect of diabetes on outcomes of hand surgery for these common diabetes-related conditions. Taken as a whole, the best current evidence supports the efficacy of surgical interventions for the management of these conditions in diabetic individuals; however, additional research is required to determine whether the treatment outcomes are equivalent to those of nondiabetic patients, and whether diabetes is associated with an increased risk of complications.

Abstract
AIM To evaluate vibration perception thresholds of patients with and without diabetes, before and after surgical carpal tunnel release. METHODS In a prospective study, 35 consecutive patients with diabetes and carpal tunnel syndrome were age and gender matched with 31 patients without diabetes having idiopathic carpal tunnel syndrome. Preoperatively, 6, 12 and 52 weeks after surgery, the vibration perception threshold of the index and little finger (median and ulnar nerve, respectively) was measured at seven different frequencies (8, 16, 32, 64, 125, 250 and 500 Hz). RESULTS At several frequencies, patients with diabetes and carpal tunnel syndrome demonstrated significantly impaired vibration perception thresholds of both the index and the little finger, before as well as after carpal tunnel release, compared with patients without diabetes with idiopathic carpal tunnel syndrome. After surgery, the overall sensibility index improved for the index finger [patients with diabetes and carpal tunnel syndrome (0.79 to 0.91, P < 0.001), patients without diabetes with idiopathic carpal tunnel syndrome (0.91 to 0.96, P > 0.05)] as well as for the little finger [patients with diabetes and carpal tunnel syndrome (0.82 to 0.90, P < 0.008), patients without diabetes with idiopathic carpal tunnel syndrome (0.95 to 0.99, P < 0.05)]. For the index finger, the sensibility index improved to a significantly higher degree for patients with diabetes and carpal tunnel syndrome not having signs of peripheral neuropathy (0.83 to 0.95, P < 0.001) compared with those with neuropathy (0.74 to 0.84, P < 0.02). Vibration perception threshold correlates with age of both patients with diabetes and carpal tunnel syndrome and patients without diabetes with idiopathic carpal tunnel syndrome, while no relationship was found based on duration of diabetes. CONCLUSIONS Vibrotactile sense is significantly impaired in patients with diabetes before and after carpal tunnel release compared with patients without diabetes. However, patients with diabetes obtained significant recovery of vibration perception threshold, particularly those without peripheral neuropathy.

Abstract
Disorders of the spine are common in clinical medicine, and spine surgery is being performed with increasing frequency in the US. Although many patients with an established diagnosis of a true surgically treatable lesion are referred to a neurosurgeon, the evaluation of patients with spinal disorders can be complex and fraught with diagnostic pitfalls. While “common conditions are common,” astute clinical acumen and vigilance are necessary to identify lesions that masquerade as surgically treatable spine disease that can lead to erroneous diagnosis and treatment. In this review, the authors discuss musculoskeletal, peripheral nerve, metabolic, infectious, inflammatory, and vascular conditions that mimic the syndromes produced by surgical lesions. It is possible that nonsurgical and surgical conditions coexist at times, complicating treatment plans and natural histories. Awareness of these diagnoses can help reduce diagnostic error, thereby avoiding the morbidity and expense associated with an unnecessary operation.

Abstract
AIMS In a cohort of men and women with Type 1 diabetes, prospectively followed for > 20 years, vibrotactile sense in fingers was investigated and related to neurophysiological tests, glycaemic level and clinical score. METHODS Out of 58 patients, diagnosed at the age of 15-25 years and recruited 1984-1985, 32 patients (13 women, median age 52 years, range 44-75 years; 19 men, median age 52 years, range 39-69 years; median duration 33.5 years, range 21-52 years) accepted follow-up in 2006. Vibration thresholds were measured in finger pulps of index and little fingers bilaterally at seven frequencies and related to results of touch (monofilaments), tactile discrimination (two-point discrimination test), electrophysiology (median nerve function), glycaemic level (HbA(1c) levels since 1984-1985) and a clinical score. RESULTS Vibrotactile sense was reduced in finger pulps, mainly in men, compared with an age- and gender-matched healthy control group with normal HbA(1c) . Vibration thresholds were increased, particularly at 250 and 500 Hz, in both index and little finger pulps. Touch and tactile discrimination correlated with vibration thresholds, but not with each other or with electrophysiology. HbA(1c) levels (at follow-up or mean values from five follow-ups since recruitment) did not correlate with any nerve function variables. Clinical scores correlated with vibrotactile sense, particularly at higher frequencies (> 125 Hz), but not with total Z-scores of electrophysiology. Duration of disease did not correlate with any variables. CONCLUSIONS Examination of vibration thresholds in index and little finger pulps may be valuable to detect neuropathy, where thresholds correlate with symptoms and tests.

Recurrent carpal tunnel syndrome--analysis of the impact of patient personality in altering functional outcome following a vascularised hypothenar fat pad flap surgery. J Hand Microsurg 2011; 4:1-6.

Abstract
We retrospectively analysed 25 patients (27 hands) who had both clinical and electrophysiological confirmation of true recurrent carpal tunnel syndrome from January 2004 to December 2009. In all the patients, after releasing the nerve a vascularised fat pad flap was mobilised from the hypothenar region and sutured to the lateral cut end of flexor retinaculum. The patient characteristics, co-morbidities, duration of symptom, interval between first release and revision surgery and intra-operative findings were assessed against post-operative relief of pain, recovery of sensory and motor dysfunction. The average age of the patients was 58 years (43-81) and the dominant hand was involved in 22 patients. Intra-operatively the nerve was compressed by scar tissue connecting the previously divided ends of the retinaculum in 18 and nine had scar tissue and fibrosis around the nerve. Following surgery 16 patients had complete recovery (asymptomatic at the first follow-up), eight had delayed recovery (partial recovery of symptoms at final follow-up) and three had a poorer outcome (persistence of preoperative symptoms at the final follow-up). The patients with delayed recovery/poorer outcome had a) Early recurrence; b) Diabetes mellitus; c) Obesity; d) Cervical spine problems; e) Involvement of non-dominant hand; and f) Intraoperative scar tissue and fibrosis. The hypothenar fat pad transposition flap provides a reliable source of vascularised local tissue that can be used in patients with recurrent carpal tunnel syndrome. The factors that were associated with poorer/delayed recovery were involvement of non-dominant hand, recurrence within a year from the previous surgery, intra-operatively scar tissue in the carpal tunnel and associated co-morbidities, like obesity diabetes mellitus and cervical spine problems.

Abstract
DM is associated with various musculoskeletal manifestations. The strength of this relationship varies among the various musculoskeletal disorders; the associations are based mostly on epidemiologic data. For most of these conditions, definitive pathophysiologic correlates are lacking.Hand and shoulder disorders occur more frequently than other musculoskeletal manifestations of DM. Recognition of the association between DM and shoulder adhesive capsulitis, DD, and stenosing flexor tenosynovitis facilitates their correct diagnosis in the setting of DM and prompt initiation of appropriate treatment, which may include optimizing glycemic control. Conversely, awareness and identification of the characteristic musculoskeletal manifestations of DM may facilitate earlier diagnosis of DM and initiation of glucose-lowering therapy to retard the development of diabetic complications.Much less has been published about the musculoskeletal complications of DM than about its micro- and macrovascular complications. Prospective case-control cohort studies are needed to establish the true prevalence of musculoskeletal complications of DM and the metabolic syndrome, especially in this era of tighter glycemic control.The potential relationship between DM and the development of OA needs to be clarified in large, prospective, case-control cohort studies. The effect on musculoskeletal manifestations of various therapeutic regimens to manage DM should be studied prospectively. Treatment regimens for some musculoskeletal conditions associated with DM, such as DISH, should be studied in larger prospective, randomized,controlled clinical trials.At the molecular level, further studies are warranted to clarify the potential contribution of AGEs and adipokines to the development of OA and diabetic musculoskeletal syndromes, such as shoulder adhesive capsulitis, DD, stenosing flexor tenosynovitis, and LJM. Identification of such molecular targets for therapy would promote the development of additional treatments for these and other rheumatic diseases.

Abstract
Carpal tunnel syndrome is the most common compression lesion of peripheral nerves with a prevalence of 4%. It is often treated by release of the flexor retinaculum, which may completely relieve the symptoms. Although such treatment is considered successful, there are probably many patients with persistent or recurrent symptoms. Recurrence implies that the patient's symptoms were initially relieved but recurred some time after the operation; this is a controversial field in which clear definitions, aetiology, diagnosis, and treatment seem uncertain. We describe recurrence of carpal tunnel syndrome and summarise possibilities for diagnosis and treatment of the condition.

Abstract
Our aim was to identify a cut-off value for self-reported, abnormal cold sensitivity and to identify cold sensitivity predictors after hand injuries. The Cold Intolerance Symptom Severity (CISS) questionnaire and a VAS question concerning discomfort on exposure to cold were investigated in 94 normal people and 88 patients. A CISS score >50 was defined as abnormal cold sensitivity. Multiple injured digits, an increased number of injured vessels, complete nerve injury and replantation were variables associated with high VAS scores. Factors linked to both abnormality and worse CISS or VAS scores were: the presence of bone injury; a larger number of repaired vessels; the use of vascular grafts and a high Hand Injury Severity Score (HISS). The causes of abnormality and severity suggest a multifactorial aetiology with bony, vascular and neural components. A cut-off for abnormality is useful for descriptive, comparative and assessment purposes.

Abstract
OBJECTIVE To compare nerve conduction study results, before and after surgical carpal tunnel release, in diabetic and non-diabetic patients. METHODS In a prospective study (2004-2007), we included 35 consecutive diabetic patients with carpal tunnel syndrome (CTS), who were age and gender matched with 31 non-diabetic patients having idiopathic CTS. Preoperatively, and at the 1 year follow-up, nerve conduction studies were performed of the median and ulnar nerve. Presence of neuropathy was based on abnormal preoperative neurophysiologic values in both the sural and the peroneal nerve. RESULTS Diabetic patients demonstrated significantly impaired nerve conduction parameters, before as well as after surgical carpal tunnel release, compared to non-diabetic patients. However, neurophysiologic recovery after carpal tunnel release was not different between the two patient groups or between diabetic patients with or without peripheral neuropathy. In general, the largest neurophysiologic recovery was demonstrated for parameters with the greatest impairment, but normal values were seldom reached. CONCLUSIONS Marked neurophysiologic impairment of the median nerve, or signs of peripheral neuropathy, does not preclude significant recovery after carpal tunnel release in diabetic patients. SIGNIFICANCE Diabetic patients with CTS should be offered the same opportunities for surgical carpal tunnel release as non-diabetic patients.

Abstract
AIMS To determine health-related quality of life (HRQL) in diabetic and non-diabetic patients with carpal tunnel syndrome (CTS) before and after surgical treatment. METHODS In a prospective study, 35 consecutive diabetic patients with CTS were age and gender matched with 31 non-diabetic patients with idiopathic CTS. At baseline (preoperatively), 6, 12 and 52 weeks after surgical carpal tunnel release, patients completed the generic Short-Form 36 (SF-36) and the disease-specific Boston Carpal Tunnel Questionnaire (BCTQ). RESULTS The SF-36 physical component scores at baseline were significantly reduced for diabetic (39+/-7.4) compared with non-diabetic patients (48+/-9.0) (P<0.05). Mixed model analysis demonstrated no differences in post-surgical improvement over time between diabetic and non-diabetic patients. The largest clinical effect was found for bodily pain (effect size 0.8). However, population norms were not reached for the diabetic patients. At baseline, no difference was found in mental component score, which deteriorated over time for diabetic patients. At baseline, BCTQ demonstrated that diabetic patients experienced more pronounced 'numbness in the hand' than non-diabetic patients. Large clinical improvements were found in both symptom severity (effect size 1.98-2.14) and functional status score (effect size 0.89-0.94) for both diabetic and non-diabetic patients, with no difference between the two patient groups. CONCLUSIONS HRQL is impaired in diabetic patients with CTS compared with non-diabetic patients with CTS and population norms. However, diabetic patients experience similar symptomatic and functional benefits from carpal tunnel release as do non-diabetic patients.

Abstract
Carpal tunnel syndrome (CTS) is the most common compressive neuropathy in the upper extremity. The condition is responsible for substantial annual costs to society, both in terms of lost productivity and the costs of treatment. Accurate diagnostic criteria, the selection of treatment strategies based on high-level evidence, and outcomes data have been inconsistent despite the prevalence of the condition. The increased awareness of the need for evidence-based practice guidelines has, however, yielded important data to guide treatment of CTS. Evidence-based guidelines for diagnosis and treatment have been developed and should direct the treatment of CTS.

Abstract
The underlying basis of carpal tunnel syndrome (CTS) and the basis of its increased incidence in diabetes are unknown. We have quantified pathology in an uncompressed nerve (posterior interosseous nerve, PIN) in the forearm between diabetic and non-diabetic patients with CTS and control subjects. In an age- and gender-matched series, 26 diabetic patients with CTS and 20 non-diabetic patients with CTS underwent biopsy of the PIN at the time of surgical carpal tunnel release. Control subjects consisted of ten PIN biopsies taken postmortem and three biopsies taken at the time of wrist surgery. We found PIN myelinated nerve fibre density significantly reduced in diabetic (mean 5,373/mm2 [95% confidence interval, 4,835–5,911]) and non-diabetic (6,617/mm2 [5,697–7,537]) patients with CTS compared to control subjects (9,109/mm2 [7,967–10,250], P < 0.001). Furthermore, diabetic patients had a significantly lower density than non-diabetic patients (P < 0.03). Endoneurial capillary density was also reduced in diabetic (58/mm2 [50–66]) and non-diabetic (67/mm2 [55–78]) patients compared to control subjects (86/mm2 [72–101], P < 0.02) with no difference between diabetic and non-diabetic patients with CTS. Our results suggest that a reduction in myelinated nerve fibre and capillary densities may predispose patients, particularly those with diabetes, to develop CTS.
