Aims. The aim of this study was to determine whether early surgical treatment results in better neurological recovery 12 months after injury than late surgical treatment in patients with acute traumatic spinal cord injury (tSCI). Methods. Patients with tSCI requiring surgical spinal decompression presenting to 17 centres in Europe were recruited. Depending on the timing of decompression, patients were divided into early (≤ 12 hours after injury) and late (> 12 hours and < 14 days after injury) groups. The American Spinal Injury Association neurological (ASIA) examination was performed at baseline (after injury but before decompression) and at 12 months. The primary endpoint was the change in Lower Extremity Motor Score (LEMS) from baseline to 12 months. Results. The final analyses comprised 159 patients in the early and 135 in the late group. Patients in the early group had significantly more severe neurological impairment before surgical treatment. For unadjusted complete-case analysis, mean change in LEMS was 15.6 (95% confidence interval (CI) 12.1 to 19.0) in the early and 11.3 (95% CI 8.3 to 14.3) in the late group, with a mean between-group difference of 4.3 (95% CI -0.3 to 8.8). Using multiply imputed data adjusting for baseline LEMS, baseline ASIA Impairment Scale (AIS), and propensity score, the mean between-group difference in the change in LEMS decreased to 2.2 (95% CI -1.5 to 5.9). Conclusion. Compared to late surgical decompression, early surgical decompression following acute tSCI did not result in statistically significant or clinically meaningful neurological improvements 12 months after injury. These results, however, do not impact the well-established need for acute, non-surgical tSCI management. This is the first study to highlight that a combination of baseline imbalances, ceiling effects, and loss to follow-up rates may yield an overestimate of the effect of early surgical decompression in unadjusted analyses, which underpins the importance of adjusted statistical analyses in acute tSCI research.

Introduction

MRI imaging is carried out to identify levels of degenerative disc disease, and in some cases to identify a definite surgical target at which decompression should take place. We wanted to see if repeat MRI scans due to a prolonged time between the initial diagnostic MRI scan of the lumbar sacral spine, and the MRI scan immediately pre-operatively, due for the desire for a ‘fresh’ MRI scan pre-operatively, altered the level or type of procedure that they would have.

Introduction. Degenerative cervical myelopathy (DCM) is associated with progressive neurological deterioration. Surgical decompression can halt but not reverse this progression. The Modified Japanese Orthopaedic Assessment (MJOA) tool is recommended by international guidelines to grade disease severity into mild, moderate and severe, where moderate and severe are both recommended to undergo surgical intervention. During Covid-19 Nottingham University Hospitals (NUH) NHS Trust, identified DCM patients as high risk for sustaining permanent neurological damage due to surgical delay. The Advanced Spinal Practitioner (ASP) team implemented a surveillance project to evaluate those at risk. Methods. A spreadsheet was compiled of all DCM patients known to the service. Patients were telephoned (Oct-Nov 2021) by an ASP. MJOA score was recorded and those describing progressive deterioration were reviewed by the ASP team on a spinal same day emergency assessment unit. Incident forms were completed for clinical deterioration and recorded as severe harm. Acute, progressive neurological deterioration was fast tracked for emergency surgical decompression. Results. 45 patients were telephoned, 18 (40%) had deteriorated. Of the 18, 9 underwent urgent surgical decompression, 6 still await surgery and 3 continue to be monitored. Those who had deteriorated were sent a formal apology and duty of candour letter. Conclusion. It appears that patients with a diagnosis of DCM deteriorate over time. Delays to timely surgical intervention can have a deleterious effect on patient's neurological function. Baseline assessment should be clearly documented and scoring system such as MJOA considered for effective monitoring. Safety netting for deterioration should be standard practice, and a clear pathway for emergency presentation identified. Conflicts of interest: No conflicts of interest. Sources of funding: No funding obtained

To compare the efficacy of local steroid injection with surgical decompression in treatment of carpal tunnel syndrome (CTS) in terms of frequency of pain. This randomized controlled study was conducted at the Department of Orthopaedics for a duration of 01 year, i.e. from 20th April 2016 to 19th April 2017. 130 patients with carpal tunnel syndrome with moderate (Grade 2) and severe (Grade 3) pain were included. Lottery method was used to allocate the patients randomly into two groups. Group A contained 65 patients who were subjected to surgical decompression and 65 patients were in Group B who were injected with local steroid injection. Complete history was obtained from all patients. All the surgical decompressions through mini incision technique and injections procedures were performed. Information were recorded in a pre designed Performa. Efficacy was observed significantly high in group B as compared to group A (87.7% vs. 72.3%, p=0.028). Carpal Tunnel syndrome symptoms were alleviated with surgical decompression as well as local steroid injection at a follow up done after 1 month. However the steroid injections seem to have greater efficacy than surgical decompression, hence we suggest it for routine treatment of all patients with CTS.

The postoperative course of median nerve decompression in the carpal tunnel syndrome may sometimes be complicated by postoperative pain, paresthesias, and other unpleasant symptoms, or be characterized by a slow recovery of nerve function due to prolonged preoperative injury causing extensive nerve damage. The aim of this study is to explore any possible effects of alpha lipoic acid (ALA) in the postoperative period after surgical decompression of the median nerve at the wrist. Patients were enrolled with proven carpal tunnel syndrome and randomly assigned into one of two groups: Group A: surgical decompression of the median nerve followed by ALA for 40 days. Group P: surgical decompression followed by placebo. The primary endpoint of the study was nerve conduction velocity at 3 months post surgery, Other endpoints were static 2 point discrimination, the Boston score for hand function, pillar pain and use of pain killers beyond the second postoperative day. ALA did not show to significantly improve nerve conduction velocity or Boston score. However, a statistically significant reduction in the postoperative incidence of pillar pain was noted in Group A. In addition, static 2 point discrimination showed to be significantly improved by ALA. Administration of ALA following decompression of the median nerve for carpal tunnel release is effective on nerve recovery, although this is not detectable through nerve conduction studies but in terms of accelerated and improved static two-point discrimination. The use of ALA as a supplementation for nerve recovery after surgical decompression may be extended to all types of compression syndromes or conditions where a nerve is freed from a mechanical insult. Furthermore, ALA limits post-decompression pain, including late pericicatricial pain at the base of the palm, the so called pillar pain, which seems to be associated with a reversible damage to the superfical sensitive small nerve fibers. In conclusion postoperative administration of ALA for 40 days post-median nerve decompression was positively associated with nerve recovery, induced a lower incidence of postoperative pillar pain and was associated with a more rapid improvement of static two-point discrimination. This treatment is well tolerated and associated with high levels of satisfaction and compliance, supporting its value as a standard postoperative supplementation after carpal tunnel decompression

Aim: To demonstrate that the conservative management of meralgia paraesthetica in children is effective. Method: Clinic case-notes of the senior author (CB) were retrospectively searched between January 1997 and February 2007 to identify cases of meralgia paraesthetica. Sixteen cases were discovered in fourteen patients, 6 right, 6 left, and 2 bilateral. Four patients had had previous pelvic surgery and two combined pelvic and femoral osteotomy for developmental dysplasia of the hip. One underwent bilateral pinning for slipped upper femoral epiphyses. Clinical symptoms were assessed subjectively. All patients were initially managed conservatively with NSAIDs and counselled to avoid tight fitting clothing across the waist. If symptoms had failed to settle at follow-up a local anaesthetic/steroid injection was administered to the site of maximal tenderness. Surgical decompression was performed for intractable cases. Results: There were 10 females and 4 males, with a mean age of 13.6 years (8–17). Mean follow-up was 15 months (1–50). Eleven cases (68.8%) improved with conservative management and a further three cases improved following a local anaesthetic/steroid injection. Two cases (12.5%) who did not improve with these measures underwent surgical decompression with subsequent improvement in symptoms. No side effects were reported from the either the steroid injection or surgical decompression. Conclusions: There is no current evidence supporting the management of meralgia paraesthetica in children. In adults, this elusive diagnosis is managed conservatively to good effect. This retrospective study demonstrates that conservative management is also effective in paediatric patients. In those cases where symptoms prove intractable, surgical decompression produces clinical improvement

Atraumatic compartment syndrome results from prolonged compression of a limb by an obtunded subject. It is most commonly seen in drug abusers and presentation is frequently late. The key factor in the pathogenesis is the fact that muscle necrosis precedes the development of a compartment syndrome. We set out to establish if surgical decompression of these compartment syndromes, as recommended in the literature, was justified. We reviewed 16 patients who underwent decompression of 19 limbs within our unit. Patients presented between 5 and 100 hours following their overdose (mean 30.5 hours) and surgery was performed at a mean time of 64.5 hours after admission. Surgical decompression resulted in the requirement for multiple operations, mean 3.7, and an extremely high complication rate. Infection was particularly prevalent, occurring in 10 of the 19 limbs decompressed. Only one of the 16 patients had normal limb function at follow up. Based on these results and an understanding of the pathogenesis of the condition, we conclude that surgical decompression of atraumatic compartment syndromes is illogical, leads to an increased complication rate and is therefore unjustified

Objective: The most dreaded and crippling complication of spinal tuberculosis is pott’s paraplegia. The use of instrumentation in the presence of infection is usually deferred for the fear of formation of a focus, persistence bio material centered infection, preferential bacterial colonization and production of a bio-film (glycocalyx) which protects them from host defenses and chemotherapeutic agents. Fortunately, mycobacterium tuberculosis is less adhesive and produces less bio-film than other bacteria and the likelihood of persistence infection in the presence of implants is smaller. Design: The present study is being conducted to study the positive and negative effects of decompression with instrumentation and to analyze and compare the results of conservative treatment, surgical decompression and decompression with instrumentation. Participants/Methods: The study was conducted in 56 patients. All patients of Pott’s Paraplegia admitted during June,02 to June,03 were included. According to the treatment given the patients were divided into three groups:. Group I – Conservative treatment. Group II – Surgical decompression only. Group III – Surgical decompression combined with instrumentation. Results: At different time intervals almost equal neurological recovery was found in group II and group III while slow recovery in group I. The mean ambulatory time was almost equal in group I and group II while very low (less than a week) in group III. Pain function score grade shifted towards excellency with time in all groups-- p=4.48 x 10-3 in group I, p=4.44 x 10-7 in group in II and p = 4.49 x 10-7 in group III. The change from grade B to grade A is quick in group III. Excellent grade is maximum (77.8%) in group III and nil in group I (p value at 6 in = 1.22 x 10-3 which is statistically significant

Utilization of nerve conduction studies in the investigation and management of carpal tunnel syndrome varies according to their perceived usefulness and availability. The use of steroid injections and splinting also varies according to service availability and their perceived effectiveness. We present a three year follow up of 230 patients managed in an environment where nerve conduction testing was not readily available. The majority received splinting and a steroid injection in an effort to manage their symptoms conservatively in the first instance. Our results show that a clear majority of patients who were treated with initial splinting and steroid injections saw a recurrence of their symptoms (71.9% and 79.7% respectively) requiring eventual surgical decompression. These results would seem to suggest that conservative management of carpal tunnel does not produce the desired curative results and that there may be an argument for proceeding directly to surgery. We also showed that 55% of patients referred for Nerve Conduction Studies seem to progress to surgical decompression. This would seem to suggest that Nerve Conduction Studies could form a robust part of the standard investigation of carpal tunnel in order to identify those who would benefit from surgery

Initial treatment of traumatic spinal cord injury remains as controversial in 2023 as it was in the early 19th century, when Sir Astley Cooper and Sir Charles Bell debated the merits or otherwise of surgery to relieve cord compression. There has been a lack of high-class evidence for early surgery, despite which expeditious intervention has become the surgical norm. This evidence deficit has been progressively addressed in the last decade and more modern statistical methods have been used to clarify some of the issues, which is demonstrated by the results of the SCI-POEM trial. However, there has never been a properly conducted trial of surgery versus active conservative care. As a result, it is still not known whether early surgery or active physiological management of the unstable injured spinal cord offers the better chance for recovery. Surgeons who care for patients with traumatic spinal cord injuries in the acute setting should be aware of the arguments on all sides of the debate, a summary of which this annotation presents.

The Patient Evaluation Measure (PEM) was designed at the Derby consensus meeting in 1995. It was validated for Carpal Tunnel Syndrome (CTS) in 2005 (Hobby et al) and was preferable to the DASH score for CTS assessment. We aimed to audit CTS treated by surgical decompression in our unit using the PEM, and to compare our results with the published literature. Thirty consecutive patients undergoing carpal tunnel decompression were questioned about one hand. Patients completed a preoperative PEM and a postoperative PEM at 3 months. Mean PEM scores improved from 41.3 to 23.9 (P< 0.001). Individual questions showed statistically significant improvements in mean scores: Feeling in the hand, Cold intolerance, Pain, Dexterity, Movement and Hand in general (all P< 0.001): Work (P< 0.005): ADL (P< 0.01): Movements, Grip and Appearance (P< 0.05). Our results are similar to previously published series, both overall, and for individual questions in the PEM. Results for Carpal Tunnel Decompression in our unit match those of other units. We found the PEM was easy to use; and effective, both in the assessment of patients with CTS, and for outcome measurement following surgical decompression. Our study supports the idea that the PEM could be used widely as an audit tool, to assist Hand Surgeon and/or Hand Surgery Unit Appraisal

Introduction. Cauda Equina is a condition requiring urgent operative intervention to avoid debilitating long term neurological compromise. The recommended maximium time delay before lack of surgical decompression results in persisting neurological deficit has been suggested to be 24 hrs and more recent studies have even indicated 48 hours as acceptable. We wanted to assess if any persisting neurological deficit occurred in our practice when treated at 12 hours or less. Aim. To assess if patients treated within half of the maximum recommended time for surgical decompression following cauda equina i.e 12 hours, are still pre-disposed to persisting neurological compromise. Methods. We reviewed all patients who underwent a spinal decompression for cauda equina, based on clinical presentation, examination and magnetic resonance imaging at our institution. Over a seven year period, seven patients were found to have operative findings consistent with cauda equina syndrome. The clinical presentation, time from presentation to operative decompression and type of procedure done, as well as the clinical review at follow up, were noted. Results. The time from presentation to operation was 8 hours 30 mins to 11 hours 48 in 6 patients and 25 hrs in one patient. All seven patients had resolution of symptoms except for dermatomal sensory deficit. Two patients had some recurrence of sciatica, two of these patients having similar operations done at the same level within 18 months. Discussion. Our study shows that urinary compromise resolves with early decompression but that persisting neurological symptoms in the form of sensory deficit can persist even when decompression is performed within 12 hours. We conclude that early decompression is necessary but it does not alleviate all neurological symptoms

CECS is an exercised induced condition that causes pain, typically in the lower limbs, and is relieved by rest. It is often seen in military personnel significantly restricting their duties. Conservative treatment is rarely successful and patients often require surgical decompression by fasciotomy or fasciectomy. All IMP (intramuscular pressure) tests (n=286) carried out between December 2007 and October 2010 on patients with suspected CECS in the anterior compartment of the lower leg were reviewed. The treatment and outcomes of those referred for surgery were analysed. Pre- and post-surgery military medical grading for leg function was extracted from the medical records system. Independent t-tests compared differences between patients that had surgery or did not. The Wilcoxon signed-rank test compared grades before and after surgery. According to the diagnostic criterion, 80% of patients undergoing IMP testing had CECS. Of these, 179 (68%) patients underwent surgery, 17 (9%) of these were for recurrent symptoms. Almost all decompressions were bilateral (95%). The majority of operations (121) were fasciectomies of the anterior compartment only and were performed by 2 surgeons. The remaining operations (58) were performed by 6 surgeons and were fasciotomies of both anterior and lateral compartments. The mean time from testing to surgery was 24 (median 11) weeks. There were 23 (13%) complications other than recurrence including 16 wound infections, 6 seromas and 1 haematoma. Pre- and post-surgery grading was available for 67% of patients. These patients had significantly better leg function after surgery (Z=−3.67, p<0.001). Of these, 47% improved, 38% showed no improvement and 15% had a poorer outcome had. Those who had a fasciectomy were significantly more likely to improve than those who had a fasciotomy (p=0.023, rho=−1.96). Our results demonstrate that patients generally improve lower limb function following surgical decompression. However, 53% showed no improvement or deteriorated in their medical grading. In addition, there is a high diagnosis rate for CECS following IMP measurement. This may reflect the poor validity of the diagnostic criterion or this could be due to good clinical selection for testing. Furthermore, fasciectomy shows a greater correlation with improved outcome than fasciotomy. There is a need to develop more accurate diagnostic criteria and to evaluate the benefits of standardising surgical technique

The optimal management of patients with the diagnosis of a spinal epidural abscess (SEA) remains controversial. The purpose of this study was to describe the clinical characteristics of patients presenting with spontaneous SEA and to correlate presentation and treatment with clinical and neurological outcome. A retrospective review of the medical records and radiology of patients with a diagnosis of SEA, treated between September 2003 and December 2010, at a tertiary referral hospital was performed. A total of 46 patients were identified including 27 males and 19 females. Mean age was 61 years (range, 30 – 86 years). At presentation, all patients had axial pain and 67% had a neurological deficit, out of which one third had paraplegia or quadriplegia. 32% patients were febrile. Diabetes was the most common risk factor (30%) followed by malignancy (17%), intravenous drug use (6%) and alcoholism (2%). Organisms were cultured in 44 patients with Methicillin Sensitive Staphylococcus Aureus most common (68%), followed by Methicillin Resistant Staphylococcus Aureus (14%). The epidural abscess was located in the lumbar spine in 24 patients, thoracic spine in 11 patients and cervical spine in 11 patients. 61% of patients had a concurrent source of septic focus on presentation, including psoas abscess (24%), facet joint septic arthritis (15%), pneumonia (11%), infective endocarditis (7%) and urosepsis (4%). 26% of patients were treated non-operatively, with computed tomography-guided aspiration and/or intravenous antibiotics based on cultures, whereas 74% underwent surgical decompression with or without fusion in combination with antibiotics. The mean inpatient hospital stay was 42 days (range, 2 – 742 days) and 34% of patients required an average of 40 days of Intensive Care Unit admission. At time discharge from hospital, of the patients managed nonoperatively, 33% had improved neurological function, 17% had worsened neurological function, 17% died and data was unavailable in 33%. Of the patients treated with surgery, 74% had improved neurological function, 6% remained unchanged, 6% had worsened neurologic function, 6% died and data was unavailable in 9% at time of discharge. SEA remains a severe condition associated with multiple septic foci and significant morbidity. Surgical decompression combined with antibiotics is associated with superior neurologic recovery compared with non-operative management, however a significant proportion of patients still deteriorate or die. Early diagnosis and management may prevent or reduce permanent neurologic deficit

Purpose of the study: Progressive cervical myelopathy secondary to cervical stenosis is generally treated surgically. Results of surgical decompression are generally good, but the progression and the type of neurological recovery have not been studied. We followed a cohort of patients who underwent cervical decompression in order to study the kinetics and the mode of the neurological recovery after surgery. Material and methods: This was a prospective mono-centric observation study conducted in a routine clinical setting. The cohort included 60 patients (mean age 65.7 years) who underwent surgery around 2006. Inclusion criteria were an association of stenosis documented on the imaging and clinical signs of medullary compression. One surgeon performed all interventions (80% posterior approach, 15% anterior and 5% mixed). Preoperative evaluation used complete cervical imaging and three validated function tests: the global JOA score, the Crockard walking test, and the nine-hold plug test of manual dexterity (9HPT) for both hands. Patients were reviewed postoperatively at 1, 3, 6, 12, 18 and 24 months. Two populations were distinguished: group 1 with mild to moderate compression: mean preoperative JOA > 10; group 2 with severe compression: mean pre-operative JOA ≤10. Results: The mean preoperative JOA was 11.7/17 (5; 15), the mean Crockard 34.5s (24; 140), and the mean time for the 9HPT 23s for both hands. Analysed by group according to the JOA showed that cervical myelopathy is mainly expressed by sensorial disorders. The JOA score, the walking test and the hand dexterity test for the dominant hand described the same pattern of recovery with a clear improvement for the first three postoperative months then a neurological stabilisation of the acquired improvement on a plateau that persisted till the end of follow-up. There was no improvement in the non-dominant hand. The same pattern was observed in both groups: the severe group presented a better improvement, reaching a final JOA score equivalent to that in the “mild-to-moderate” group. Discussion: The pattern of recovery of cervical neurological deficits occurs rapidly during the first three months following surgical decompression, then stabilises on a plateau, irrespective of the severity of the initial condition. The benefit is certain for initially severe compression

Awake Rapid Heavy-Weight Closed Reduction (ARHWCR) with weights from 18 to 72 kg was used to reduce six unilateral and nine bilateral cervical facet dislocations. Frankel grading ranged from A to E. Reduction was achieved in all 15 patients with no neurological deterioration. Motor ASIA score improved from a prereduction mean of 64 points to 73 after reduction. Before and after reduction, MRI studies were done on all 15 patients. ARHWCR was done irrespective of the MRI findings. The MRI results were evaluated by five orthopaedic surgeons, five neurosurgeons and five radiologists. The radiologists reported 55% disc herniation in four neurologically-intact patients. On pre-reduction MRI, 34% of anterior longitudinal ligaments and 64% of posterior longitudinal ligaments were reported to be disrupted. They were reported intact on post-reduction MRI. These findings indicate that MRI studies may be open to misinterpretation. Viewing the prereduction MRI, the orthopaedic and neurosurgeons opted for surgical decompression and reduction in 53% of cases. Looking at the post-reduction MRI, they felt that reduction was adequate in 80.6% of cases, but on personal judgment believed that surgical decompression might be of benefit in the remaining 19.4%. ARHWCR is an effective, safe and rapid way of relieving cord compression. Prereduction MRI, irrespective of the patient’s neurological status, is not indicated in acute cervical facet dislocations and can lead to unnecessary surgical intervention

Object: To study the incidence, etiology and management of patients with neuralgia following Posterior Lumbar Interbody Fusion (PLIF). Design: A prospective study of 85 patients undergoing PLIF surgery from March 1996 to March 2001. Subjects: Seven of the 85 patients undergoing PLIF surgery developed new leg pain between three days and five months following surgery. Results: The incidence of neuralgia was 8%. In all the patients the post-surgical neuralgia was in a new distribution. MRI examination ruled out misplaced pedicle screws in all cases, but was otherwise unhelpful. One patient developed neuralgia five months post-operatively due to collapse of the cortico-cancellous graft and secondary foraminal narrowing. This was not relieved following surgical decompression. Four patients had neuralgia caused by relative stenosis of the exiting nerve (3) or the traversing nerve (1) which started between three days and two weeks after surgery. The pain was relieved in all four following surgical decompression. One patient had leg pain when lying down; standing and sitting relieved this. A loose lamina was found on exploring the wound. Her pain settled after surgery. One patient developed a spondylolisthesis at the level below a L4/5 PLIF four months after surgery. Her pain was eased by stabilization of the lower segment. Conclusions: MRI scans are not very helpful in these cases. Early exploration is recommended and gave good results in six of our seven cases

Aim: Osteoarthritis of the wrist is a well recognised cause of secondary carpal tunnel syndrome. The aim of the study is to compare the outcome following carpal tunnel decompression with regard to patient satisfaction. We compared the outcome of carpal tunnel decompression between patients with and with out osteoarthritis of the wrist. Patients and Methods: The study was done retrospectively. Clinical notes of all the patients who underwent carpal tunnel decompression over a period of 8 years were verified. Twenty four patients who underwent surgical decompression for carpal tunnel syndrome secondary to osteoarthritis were identified by reviewing the notes and the radiographs. Control group consisted of 24 patients who under went carpal tunnel decompression but without osteoarthritis of the wrist. The control group was matched for age, sex, side, and neuro-physiological severity of the nerve compression. Clinical notes were verified to find whether the patients were satisfied with the symptom relief at the first post-operative follow up visit. Results: There were 24 patients in the group with osteoarthritis of the wrist. The mean age of the patients was 71 years (range 33–89 years). There were 19 females and five males. The right hand was involved in 17 patients and the left was involved in 7 patients. The control group with out osteoarthritis also had similar distribution regarding age sex side, and neuro-physiological severity of nerve conduction. In the group with osteoarthritis of the wrist 17(71%) patients reported the their symptom relief as satisfactory and the rest seven(29%) reported the results as unsatisfactory. In the control group 23(96%) patients reported their symptom relief as satisfactory and one (4%) reported their results as unsatisfactory (P= 0.0325). Conclusions: Patient satisfaction following surgical decompression in patients with secondary carpal tunnel syndrome due to osteoarthritis is significantly lower compared to patients with out osteoarthritis of the wrist. Patients with osteoarthritis of the wrist should be warned about the higher incidence of poor outcome prior to decompression

Tibialis posterior tendon (TPT) dysfunction is a disorder of unknown aetiology. Trauma, inflammatory processes, anatomical abnormalities and iatrogenic factors have all been implicated as causative mechanisms. The condition presents with pain and swelling around the medial malleolus. The pain is characteristically worse on exercise and relieved by elevation. The disorder has been classified by Johnson and Strom (1989); stage I is characterized by pain around the medial malleolus and mild weakness of single heel raising. Without treatment the condition may progress to a fixed valgus deformity along with pes planus. Aim. To assess the outcome of surgical decompression of stage I TPT dysfunction. Method. Ten cases were identified, operated on by a single surgeon over a three-year period. The patients were assessed in a dedicated clinic by administration of a questionnaire and by clinical examination. Results. Nine patients with an average age of 30 years (13–51) agreed to participate in the study. Six of the nine patients recalled a sporting injury to the ankle prior to onset of symptoms. Eight of these of patients underwent a course of physiotherapy prior to surgery. After decompression all patients reported reduction of pain as measured using a visual analogue scale, with five patients reporting complete resolution of pain. Patients experienced relief of pain on average four weeks (1.5–6) after surgery. All patients were able to return to work and normal leisure activities after appropriate rehabilitation. Conclusions. Decompression of the tibialis posterior tendon in stage I dysfunction leads to pain relief and enables an early return to normal activities. Therefore surgical decompression of the tibialis posterior tendon may be considered in cases of stage I dysfunction which are refractory to conservative measures, particularly in young and active patients
