Aims. The sensitivity and specificity of electrodiagnostic parameters in diagnosing carpal tunnel syndrome (CTS) have been reported differently, and this study aims to address this gap. Methods. This case-control study was conducted on 57 cases with CTS and 58 controls without complaints, such as pain or paresthesia on the median nerve. The main assessed electrodiagnostic parameters were terminal latency index (TLI), residual latency (RL), median ulnar F-wave latency difference (FdifMU), and median sensory latency-ulnar motor latency difference (MSUMLD). Results. The mean age in cases and controls were 50.7 years (SD 9.9) and 47.9 years (SD 12.1), respectively. The CTS severity was mild in 20 patients (34.4%), moderate in 19 patients (32.8%), and severe in 19 patients (32.8%). The sensitivity and specificity of the electrodiagnostic parameters in diagnosing CTS were as follows: TLI 75.4% and 87.8%; RL 85.9% and 82.5%; FdifMU 87.9% and 82.9%; and MSUMLD 94.8% and 60.0%, respectively. Conclusion. Our findings indicated that electrodiagnostic parameters are significantly associated with the clinical manifestation of CTS, and are associated with high diagnostic accuracy in CTS diagnosis. However, further studies are required to highlight the role of electrodiagnostic parameters and their combination in CTS detection. Cite this article: Bone Jt Open 2024;5(10):898–903

Aims. The aim of this study was to assess the clinical and radiological results of patients who were revised using a custom-made triflange acetabular component (CTAC) for component loosening and pelvic discontinuity (PD) after previous total hip arthroplasty (THA). Methods. Data were extracted from a single centre prospective database of patients with PD who were treated with a CTAC. Patients were included if they had a follow-up of two years. The Hip Disability and Osteoarthritis Outcome Score (HOOS), modified Oxford Hip Score (mOHS), EurQol EuroQoL five-dimension three-level (EQ-5D-3L) utility, and Numeric Rating Scale (NRS), including visual analogue score (VAS) for pain, were gathered at baseline, and at one- and two-year follow-up. Reasons for revision, and radiological and clinical complications were registered. Trends over time are described and tested for significance and clinical relevance. Results. A total of 18 females with 22 CTACs who had a mean age of 73.5 years (SD 7.7) were included. A significant improvement was found in HOOS (p < 0.0001), mOHS (p < 0.0001), EQ-5D-3L utility (p = 0.003), EQ-5D-3L NRS (p = 0.013), VAS pain rest (p = 0.008), and VAS pain activity (p < 0.0001) between baseline and final follow-up. Minimal clinically important improvement in mOHS and the HOOS Physical Function Short Form (HOOS-PS) was observed in 16 patients (73%) and 14 patients (64%), respectively. Definite healing of the PD was observed in 19 hips (86%). Complications included six cases with broken screws (27%), four cases (18%) with bony fractures, and one case (4.5%) with sciatic nerve paresthesia. One patient with concurrent bilateral PD had revision surgery due to recurrent dislocations. No revision surgery was performed for screw failure or implant breakage. Conclusion. CTAC in patients with THA acetabular loosening and PD can result in stable constructs and significant improvement in functioning and health-related quality of life at two years' follow-up. Further follow-up is necessary to determine the mid- to long-term outcome. Cite this article: Bone Jt Open 2023;4(2):53–61

Pelvic discontinuity (PD) is a detrimental complication following total hip arthroplasty (THA). The aim of this study was to assess the clinical and radiological results of patients with PD who were revised using a custom-made triflange acetabular component (CTAC). This is a single centre prospective study of patients with PD following THA who were treated with a CTAC. The Hip Disability and Osteoarthritis Outcome Score (HOOS), modified Oxford Hip Score (mOHS), EurQol five-dimension three-level (EQ-5D-3L) utility, and Numeric Rating Scale (NRS), including visual analogue score (VAS) for pain, were gathered at baseline, and at one- and two-year follow-up. Clinical and radiological complications, including reasons for revisions were registered. Trends over time are described and tested for significance and clinical relevance. 18 females with 22 CTACs were included with a mean age of 73.5 years (SD 7.7). There were significant improvements between baseline and final follow-up in HOOS (p<0.01), mOHS (p<0.01), EQ-5D-3L utility (p<0.01), EQ-5D-3L NRS (p<0.01), VAS pain rest (p<0.01), and VAS pain activity (p<0.01). A minimal clinically important improvement in mOHS and the HOOS was observed in 16 patients (73%) and 14 patients (64%), respectively. Definite healing of the PD was observed in 19 hips (86%). Complications included six cases with broken screws (27%), four cases (18%) with bony fractures, and one case (4.5%) with sciatic nerve paresthesia. One patient with concurrent bilateral PD had revision surgery due to recurrent dislocations. No revision surgery was performed for screw failure or implant breakage. This is the first prospective assessment in clinical outcome of patients with PD who were treated with a CTAC. We have demonstrated that CTAC in patients with THA acetabular loosening and PD can result in stable constructs with no mechanical failures. Moreover, clinically relevant improvements in health-related quality of life at two years’ follow-up was observed

Osteochondromas are benign chondrogenic lesions arising on the external surface of the bone with aberrant cartilage (exostosis) from the perichondral ring that may contain a marrow cavity also. In a few cases, depending on the anatomical site affected, different degrees of edema, redness, paresthesia, or paresis can take place due to simple contact or friction. Also, depending on their closeness to neurovascular structures, the procedure of excision becomes crucial to avoid recurrence. We report a unique case of recurrent osteochondroma of the proximal humerus enclosing the brachial artery which makes for an important case and procedure to ensure that no relapse occurs. We report a unique case of a 13-year-old female who had presented with a history of pain and recurrent swelling for 5 years. The swelling size was 4.4 cm x 3.7 cm x 4 cm with a previous history of swelling at the same site operated in 2018. CT reports were suggestive of a large well defined broad-based exophytic diaphyseal lesion in the medial side of the proximal humerus extending posteriorly. Another similar morphological lesion measuring approximately 9 mm x 7 mm was noted involving the posterior humeral shaft. The minimal distance between the lesion and the brachial artery was 2 mm just anterior to the posterio-medial growth. Two intervals were made, first between the tumor and the neurovascular bundle and the other between the anterior tumor and brachial artery followed by exostosis and cauterization of the base. Proper curettage and excision of the tumor was done after dissecting and removing the soft tissue, blood vessels, and nerves so that there were very less chances of relapse. Post-operative X-ray was done and post 6 months of follow-up, there were no changes, and no relapse was observed. Thus, when presented with a case of recurrent osteochondroma of the proximal humerus, osteochondroma could also be in proximity to important vasculature as in this case enclosing the brachial artery. Thus, proper curettage and excision should be done in such cases to avoid recurrence

Background. Percutaneous endoscopic interlaminar discectomy (PEID) has achieved favorable effects in the treatment of lumbar disc herniation (LDH), as a new surgical procedure. With its wide range of applications, a series of complications related to the operation has gradually emerged. Objective. To describe the type, incidence and characteristics of the complications following PEID and to explore preventative and treatment measures. Study Design. Retrospective, observational study. Setting. A spine center affiliated with a large general hospital. Method. In total, 479 cases of patients with LDH received PEID, which was performed by an experienced spine surgeon between January 2010 and April 2013. Data concerning the complications were recorded. Result. All of the 479 cases successfully received the procedure. A total of 482 procedures were completed. The mean follow-up time was 44.3 months, ranging from 24 to 60 months. The average patient age was 47.8 years, ranging from 16 to 76 years. There were 29 (6.0%) related complications that emerged, including 3 cases (0.6%) of fragment omission, and the symptoms gradually eased following 3–6 weeks of conservative treatment; 2 cases (0.4%) of nerve root injury, and the patients recovered well following 1–3 months of taking neurotrophic drugs and functional exercise; 15 cases (3.1%) of paresthesia, and this condition gradually improved following 3–6 weeks of rehabilitation exercises and treatment with mecobalamin and pregabalin; and recurrence occurred in 9 cases (1.9%), and the condition was controlled in 4 of these cases by using a conservative method, while 5 of the cases underwent reoperation, including 3 traditional open surgeries and 2 PEID. Furthermore, the complication rate for the first 100 cases was 16%. This rate decreased to 3.4% (for cases 101–479), and the incidence of L4–5 (8.2%) was significantly higher than L5-S1 (4.5%). Limitations. This is a retrospective study, and some bias exists due to the single-center study design. Conclusion. PEID is a surgical approach, which has a low complication rate. Fragment omission, nerve root injury, paresthesia and recurrence are relatively common. Some effective measures can prevent and reduce the incidence of the complications, such as strict indications for surgery, a thorough action plan and skilled operation skills

Background. Total hip arthroplasty (THA) has been and continues to be the gold standard for treatment of end-stage osteoarthritis. With each year, implant characteristics are evolving to increase patient-reported outcomes and decrease complications. Purpose: to report minimum 2-year outcomes and complications in patients who underwent robotic-arm assisted THA using Corin versus Stryker-type implants. Methods. Data were prospectively collected on patients who underwent THA with Corin-type implants (both cup and stem) and THA using Stryker implants between June 2011 and July 2016. A 1:1 propensity match was performed using the following 5 covariates: age, body mass index, gender, Charlson score and smoking status. Surgical outcomes were assessed at minimum 2-year follow-up using the Forgotten Joint Score (FJS), Harris Hip Score (HHS), Veterans RAND 12-item physical and mental health survey, Short Form 12 physical and mental health survey, Visual Analog Score (VAS), and patient satisfaction. The exclusion criteria were previous hip condition/surgery, workers compensation, or were unwilling. Results. Of the eligible 774 cases, 645 patients (83.3%) had minimum 2-year follow-up and met inclusion and exclusion criteria. Of the 645 patients, 323 had Corin implants, and 155 had Stryker implants. The 1:1 propensity match successfully yielded 290 patients (145 per implant group) which had a minimum 2-year follow-up at a mean 38.3 months (range, 24.1–65.3 months). Average age was 59.9 (range, 34.92–79.89 Stryker group, 30.65–75.92 Corin group) for each group and average BMI were 30.0 (range, 19.05–49.33) kg/m. 2. for the Stryker group and 29.77 (range, 20.15–55.37) kg/m. 2. for the Corin group. FJS (P=0.0388) and patient satisfaction (P=0.0019) were significantly higher in the Stryker implant group than the Corin implant group. There were nine cases of postoperative thigh numbness or paresthesias, three cases of wound infection, and one case of nonunion in the Corin-implant group. There were four cases of postoperative thigh numbness or parasthesias and six cases of wound infection in the Stryker-implant group. Conclusion. At minimum 2-year follow-up, patients who had undergone THA with Stryker-type implants had significantly higher FJS and satisfaction and a trend toward decreased complications than patients with Corin-type implants. These results can help guide decision making for surgical instrumentation by arthroplasty surgeons

Aim: Fixation implants are usually well tolerated by the patients for prolonged periods of time. However, it is not unusual for some patients to develop persistent pain with acute onset that is often combined with paresthesias. The purpose of this study was to verify if the acute onset of pain that is not combined with clinical or laboratory signs of infection could be attributed to an underlying bacterial colonization of implants. Methods: Sixty-four patients (38 male and 26 female) with mean age of 36 years (range, 10 to 73 years) were included in this study. Patients presented with acute onset of pain and/or paresthesias several years after the implantation of stainless-steel þxation materials (plate-screws: 52 and intramedullary nails: 12), in the upper (13) or lower extremity (51). All patients of the present series had negative clinical and laboratory signs of infection. All patients of the present series had their þxation materials removed in our department. The materials subsequently underwent microbiologic and corrosion evaluation. Results: Patients experienced immediate relief after removal of þxation materials. Cultures were positive in 18% of cases and Staph aureus and epidermidis were most frequently encountered. Pseudomonas and enterococcus were also cultured. Conclusions: The percentage of positive cultures (18%) in the patients of our series indicates that symptoms may be due to the bacterial colonization of implants, despite the absence of sings of infection. Although the administration of antibiotics remains controversial, removal of the implants is indicated in cases with acute delayed onset of pain at the site of the implanted þxation materials

Purpose of the study: We report the results of a prospective series of 104 cases of carpal tunnel decompression using a minimally invasive technique performed by one operator. Material and methods: The 92 patients (28 men) were treated in an outpatient clinic between February 1999 and July 2002. Mean age was 50 years and 86% of the cases involved the dominant side. Twenty-one patients were manual laborers. There was a notion of repeated motion (occupational disease) in nine cases and eight patients were diabetics. Nocturnal paresthesia predominated the clinical presentation in all patients. Anesthesia of the median nerve territory was noted in five patients. There was no motor deficit. The technique consisted in decompression of the carpal tunnel under local anesthesia via an incision in the flexion fold of the wrist and introduction of a pre-moulded canulated probe into the carpal tunnel then section of the anterior retinacular ligament using a n°15 lancet guided by the probe. Patients were reviewed at 15 days, then one, three and six months. Results: Outcome was excellent or good in 97.2%. One patient was partially relieved: this diabetic patient retained decreased sensitivity in the median nerve territory but the nocturnal paresthesia resolved completely. Two patients underwent decompression on both sides (same technique) and continued to complain about pain on one side. There were no neurological, tendinous, or infectious complications and no conversion to open surgery was required. Mean duration of sick leave was 22.3 days and daily activities were resumed without pain at the base of the hand on average 15 days after surgery. Conclusion: The results obtained with this minimally invasive non-endoscopic technique are comparable with endoscopic techniques but at a lesser cost

Femoral nerve block is a reliable and effective method of providing anaesthesia and analgesia in the peri-operative period but there remains a small but serious risk of neurological complication. We aimed to determine incidence and outcome of neurological complications following femoral nerve block in patients who had major knee surgery. During the period January 2003 to August 2008, medical records of all patients undergoing knee surgery by Dr Myles Coolican and Dr David Parker, who had been administered femoral block for peri-operative analgesia, were evaluated. Patients with a neurological complication were invited take part in the study. A detailed physical examination including sensory responses, motor response and reflexes in both limbs was performed by an independent orthopaedic surgeon. Subjective outcome and pain specific questionnaires as well as clinical measurements were also collected. Out of 1393 patients administered with femoral nerve block anaesthesia during this period, 28 subjects (M:F= 5:23) were identified on the basis of persistent symptoms (more than three months) of femoral nerve dysfunction. All the patients had sensory dysfunction in the autonomous zone of femoral nerve sensory distribution. The incidence of neurological complications was 2.01%. One patient was deceased of unrelated causes and five patients declined to participate in the study. 14 patients out of the 22 have been examined so far. Nine cases had a one shot nerve block and five had continuous peripheral nerve block catheter. Areas of hypoesthesia/anaesthesia involving femoral nerve distribution occurred in 7 subjects and hyperaesthesia/paresthesia occurred in four. One subject had a combination of hypoesthesia and hyperesthesia in different areas of the femoral nerve distribution. Three subjects had bilateral symptoms following bilateral simultaneous nerve blocks. Dysesthesias in the affected dermatomes were found in seven cases and paresthesias were found in eight cases. Douleur Neuropathique en 4 questions (DN4) score of ï. 3. 4 was found in all the patients (average value: 5.55). The average scores for tingling, pins and needles and burning sensation (in a scale from 0 to 10) are 3.8, 3.1 and 2.9 respectively. The incidence of persistent neurological complication after femoral nerve block in our series is much higher compared to the reported incidence in the contemporary literature (Auroy Y. et al. Major complications of regional anesthesia in France: Anesthesiology 2002; 97:1274 80). The symptoms significantly influence the quality of life in the affected cases and question the value of the femoral nerve block in knee surgery

Introduction. Ascertaining the etiology of hip pain in young patients can be challenging. Osteoid osteoma about the hip has only been described in case reports and small case series in this sub-population. This study assessed the clinical course, radiologic findings, and treatment approaches in a large series of pediatric osteoid osteoma cases about the hip. Potential diagnostic and treatment pitfalls were identified. Methods. A single-center tertiary care departmental database was queried for all cases of osteoid osteoma seen between Jan 1, 2003 and December 31, 2015. Medical records were reviewed to identify those with lesions identified within or around the hip joint. Clinical, demographic, and radiologic data were analyzed. Results. Fifty children and adolescents (56% female, mean age 12.4 years, range 3–19 years) were identified with osteoid osteoma about the hip. The femoral neck was the most common lesion location (38%), and pain in the hip was the most common presenting chief complaint (60%). Night pain (90%) and symptom relief with NSAIDs (88%) were extremely common, though not universally reported. Sclerosis and/or cortical thickening was visible in 58% of radiographs, though a lucent nidus was visible in only 42%. Thirty patients (60%) underwent MRI, 27 of which were available for review, with focal peri-lesional edema as a universal finding. Amongst intracapsular lesions (n=17, 63%), common findings included medial retinacular thickening (33%), synovitis (45%) and effusion (76%). In the 43 patients (48%) who underwent CT, a diagnostic lucent nidus was a universal finding. Initial alternative diagnoses were recorded in 46% of cases, including, in order of decreasing frequency, femoro-acetabular impingement, minor trauma, hip synovitis, ‘growing pain’, stress fracture, and infection. Abnormal hip range of motion, positive impingement signs, and global synovitis on MRI scan were found to be associated with alternative diagnosis. On multivariate regression analysis, only abnormal hip ROM was independently predictive of alternative diagnosis. Delay in diagnosis of >6 months was seen in 43% of patients. Three patients underwent preceding operative procedures for other hip diagnoses, but had persistent hip pain until the osteoid osteoma was treated. Forty-one patients (82%) ultimately underwent radiofrequency ablation (RFA), and 1 open osteoid osteoma resection was performed. Of those who underwent RFA, 93% achieved complete symptom resolution, with 2 of 3 patients without symptom resolution undergoing revision RFA procedure, 1 of which led to symptom resolution. Complications of treatment included 1 case of deep infection along an RFA track, requiring operative debridement, 1 case of transient weakness and paresthesias in the involved extremity, and 1 case of fracture at the RFA site, requiring ORIF. Conclusions. Alternative andelayed diagnoses are common in osteoid osteoma about the hip, with femoro-acetabular impingement representing the most common alternative initial diagnosis in our series. While varying presenting complaints and nonspecific MRI findings may contribute to diagnostic uncertainty, night pain was present in the vast majority of cases and CT scans provided definitive diagnosis in all patients who received them. As increasing numbers of young, active patients are being evaluated for various causes of hip pain, such as femoro-acetabular impingement, osteoid osteoma should not be overlooked in the differential diagnosis of pain about the hip

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

Aims

Lateral femoral cutaneous nerve (LFCN) injury is a potential complication after the direct anterior approach for total hip arthroplasty (DAA-THA). The aim of this study was to determine how the location of the fasciotomy in DAA-THA affects LFCN injury.

Aims

A local injection may be used as an early option in the treatment of Morton’s neuroma, and can be performed using various medications. The aim of this study was to compare the effects of injections of hyaluronic acid compared with corticosteroid in the treatment of this condition.

Aims

The study aimed to assess the clinical outcomes of arthroscopic debridement and partial excision in patients with traumatic central tears of the triangular fibrocartilage complex (TFCC), and to identify prognostic factors associated with unfavourable clinical outcomes.

Aims

Lateral femoral cutaneous nerve (LFCN) injury is a complication after periacetabular osteo-tomy (PAO) using an anterior approach, which might adversely affect the outcome. However, no prospective study has assessed the incidence and severity of this injury and its effect on the clinical outcomes over a period of time for longer than one year after PAO. The aim of this study was to assess the incidence and severity of the symptoms of LFCN injury for ≥ three years after PAO and report its effect on clinical outcomes.

Aims

There is evidence that morbidly obese patients have more intra- and postoperative complications and poorer outcomes when undergoing total hip arthroplasty (THA) with the direct anterior approach (DAA). The aim of this study was to determine the efficacy of DAA for THA, and compare the complications and outcomes of morbidly obese patients with nonobese patients.

Aims

There are concerns regarding complications and longevity of total elbow arthroplasty (TEA) in young patients, and the few previous publications are mainly limited to reports on linked elbow devices. We investigated the clinical outcome of unlinked TEA for patients aged less than 50 years with rheumatoid arthritis (RA).

Introduction: Symptomatic treatment of Civinini-Morton syndrome (interdigital neuritis: IDN) may be performed directly on the involved nervous branch using orthotics, local drug injections or surgery. Alcoholization with phenol by a percutaneous approach has the aim to induce a permanent chemical neurolysis, obtaining remission of the neuritic painful symptoms. Methods: 71 patients were treated by percutaneous alcoholization of the interdigital nerve using a needle-electrode connected to an electrostimulator by a dorsal approach to the intermetatarsal space. Once the nerve is localized by induction of paresthesia up to the toes, 2,5 ml of phenol 5% in water solution are injected, immediately followed by local anesthetic for a post-procedure analgesia. The patients were evaluated by visual analogue scale for pain (VAS). Results: Mean follow-up was 36±8 months. Percutaneous alcoholization of the common interdigital nerve by phenol injection proved to be effective (VAS < 30) in 80.3% of cases (57/71). Conclusions: Treatment of Civinini-Morton syndrome by alcoholization with phenol by a percutaneous approach showed considerable better results when compared with those reported in the literature with conservative treatment or local steroid injection, and even comparable with those obtained with surgical nevrectomy in absence of complications related to surgical approach

Introduction. Ulnar nerve entrapment is the second most common nerve entrapment syndrome of the upper extremity. Despite this, only a few studies have assessed the outcome of ulnar nerve decompression. The objectives of the study were to review the pre-operative symptoms, nerve conduction studies, the co-morbidities, operative procedures undertaken and the post-operative outcomes; and investigate and ascertain prognostic factors particularly in cases of persistence of symptoms after the surgery. Methods. We reviewed the case notes of ulnar nerve decompressions surgery performed over a period of six year period. A structured proforma was created to document the demographics, patient complaints, method of decompression, per-operative findings and symptom status at the last follow up. Outcome grading was recorded as completely relieved, improved, unchanged or worse. Analysis of data was carried out using the SPSS software (Version 16.0; Illinois). The significance level was set at 5%. Results. 136 ulnar nerve decompressions formed the study group. Minimum follow-up was three months. Numbness and paresthesia in ulnar distribution were the two most common presenting symptoms (96%). The cause of compression was identified as idiopathic in 58.2%; flexor carpi ulnaris aponeurosis in 36.7% and Arcade of Stuthers in 5.1% extremities. The outcome was satisfactory in 85.2% of patients. No obvious association was demonstrated between the outcome of surgery and duration of symptoms, presence of co-morbidities or the type of surgery performed. Interestingly out of 12 patients who got worse or had no improvement, nine (75%) had either normal nerve conduction studies or none done pre-operatively. Conclusion. This is the largest review of outcomes after ulnar nerve decompressions at elbow. The study showed that good results (85.2%) of ulnar nerve decompression at elbow in majority of patients regardless of level of surgeon's experience or procedure undertaken

Purpose: Insertional calcific Achilles tendinosis is a painful, frequently disabling, condition. The longitudinal and radial alignment of the angiosomes of the posterior region of the leg makes a straight posterior midline approach logical. The safety of the posterior midline approach and the outcome of a central tendon splitting approach associated with a Strayer procedure to treat this condition was evaluated. Method: A retrospective review of a consecutive cohort of a single surgeon was performed. All patients had failed conservative treatment and all patients were primary cases. Forty-seven patients (48 heels) were treated over a 11-year period for chronic insertional Achilles tendinosis. All patients underwent a midline posterior splitting approach, debridment of the bursae, resection of the haglund deformity, partial Achilles detachment, debridement, reinsertion with bone anchor associated with a proximal gatrocnemius recession (strayer procedure) through a second midline incision. The average age was 59 years old (39–75), co-morbidities included four smokers and one diabetic patient. The average followup was 54 months (15–144). All patients answered pre-op and latest follow up AOFAS questionnaire, satisfaction rate and complications were reviewed. Results: Satisfaction rate was 100%. AOFAS score improved significantly from 59 (36–80) preop to 97 (90–100) at the latest follow-up. Complications included one superficial infection and one sural nerve paresthesia. There were no major complications. Conclusion: Achilles insertional tendinopathy treated by a posterior midline approach is a safe and reliable procedure. The procedure was associated with high patient satisfaction rate and excellent outcome
