Achilles tendon-splitting approach and double-row suture anchor repair for Haglund syndrome.

BACKGROUND: Haglund syndrom is characterized as a painful posterosuperior deformity of the heel with possible causes as tight Achilles tendon, high-arched foot and tendency to walk on the outside of the heel. Surgical treatment may be recommended in cases where of insufficient response to nonoperative treatment. This study aims to evaluate the clinical and radiographic results of central Achilles tendon splitting and double-row suture anchor technique in the surgical treatment of patients with Haglund syndrome. METHODS: 27 patients with Haglund syndrome who underwent central Achilles tendon splitting and double-row suture anchor were retrospectively evaluated. The results were evaluated by the pre- and post-operative American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale and visual analogue scale (VAS). All patients were evaluated radiographically to assess lateral talus-first metatarsal angle (TMTA), Calcaneal pitch angle (CPA), and the Fowler-Philip angle (FPA) preoperatively and postoperatively. RESULTS: The mean preoperative AOFAS score was 47 ± 7 points; at the end of the follow-up period, it increased to 92 ± 4 points (p < 0.001). The mean preoperative VAS score was 9 ± 0.9 points; at the end of the follow-up period, it was 2 ± 0.6 points (p < 0.001). The lateral TMTA (preoperative: 5° ± 2°; follow-up: 4° ± 2°; p < 0.001), CPA (preoperative: 21° ± 5°; follow-up: 20° ± 5°; p = 0.005) and FPA (preoperative: 55° ± 6°; follow-up: 32° ± 3°; p < 0.001) values decreased at the end of the follow-up period. CONCLUSION: In the absence of an improvement to nonoperative treatment methods, central Achilles tendon-splitting approach appears to be an effective and safe treatment option. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Musculoskeletal Trauma in Critically Injured Patients: Factors Leading to Delayed Operative Fixation and Multiple Organ Failure.

BACKGROUND: Musculoskeletal injuries are common following trauma and variables that are associated with late femur fracture fixation are important to perioperative management. Furthermore, the association of late fracture fixation and multiple organ failure (MOF) is not well defined. METHODS: We performed a retrospective cohort investigation from 2 academic trauma centers. INCLUSION CRITERIA: age 18-89 years, injury severity score (ISS) >15, femoral shaft fracture requiring operative fixation, and admission to the intensive care unit >2 days. Admission physiology variables and abbreviated injury scale (AIS) scores were obtained. Lactate was collected as a marker of shock and was described as admission lactate (LacAdm) and as 24-hour time-weighted lactate (LacTW24h), which reflects an area under the curve and is considered a marker for the overall depth of shock. The primary aim was to evaluate clinical variables associated with late femur fracture fixation (defined as ≥24 hours after admission). A multivariable logistic regression model tested variables associated with late fixation and is reported by odds ratio (OR) with 95% confidence interval (CI). The secondary aim evaluated the association between late fixation and MOF, defined by the Denver MOF score. The summation of scores (on a scale from 0 to 3) from the cardiac, pulmonary, hepatic, and renal systems was calculated and MOF was confirmed if the total daily sum of the worst scores from each organ system was >3. We assessed the association between late fixation and MOF using a Cox proportional hazards model adjusted for confounding variables by inverse probability weighting (a propensity score method). A P value <.05 was considered statistically significant. RESULTS: One hundred sixty of 279 (57.3%) patients received early fixation and 119 of 279 (42.7%) received late fixation. LacTW24h (OR = 1.66 per 1 mmol/L increase, 95% CI, 1.24-2.21; P < .001) and ISS (OR = 1.07 per 1-point increase, 95% CI, 1.03-1.10; P < .001) were associated with higher odds of late fixation. Late fixation was associated with a 3-fold increase in the odds of MOF (hazard ratio [HR] = 3.21, 95% CI, 1.48-7.00; P < .01). CONCLUSIONS: In a cohort of multisystem trauma patients with femur fractures, greater injury severity and depth of shock, as measured by LacTW24h, were associated with late operative fixation. Late fixation was also associated with MOF. Strategies to reduce the burden of MOF in this population require further investigation.

Clinical course of pain and disability following primary lumbar discectomy: systematic review and meta-analysis.

PURPOSE: To conduct a meta-analysis to describe clinical course of pain and disability in adult patients post-lumbar discectomy (PROSPERO: CRD42015020806). METHODS: Sensitive topic-based search strategy designed for individual databases was conducted. Patients (> 16 years) following first-time lumbar discectomy for sciatica/radiculopathy with no complications, investigated in inception (point of surgery) prospective cohort studies, were included. Studies including revision surgery or not published in English were excluded. Two reviewers independently searched information sources, assessed eligibility at title/abstract and full-text stages, extracted data, assessed risk of bias (modified QUIPs) and assessed GRADE. Authors were contacted to request raw data where data/variance data were missing. Meta-analyses evaluated outcomes at all available time points using the variance-weighted mean in random-effect meta-analyses. Means and 95% CIs were plotted over time for measurements reported on outcomes of leg pain, back pain and disability. RESULTS: A total of 87 studies (n = 31,034) at risk of bias (49 moderate, 38 high) were included. Clinically relevant improvements immediately following surgery (> MCID) for leg pain (0-10, mean before surgery 7.04, 50 studies, n = 14,910 participants) and disability were identified (0-100, mean before surgery 53.33, 48 studies, n = 15,037). Back pain also improved (0-10, mean before surgery 4.72, 53 studies, n = 14,877). Improvement in all outcomes was maintained (to 7 years). Meta-regression analyses to assess the relationship between outcome data and a priori potential covariates found preoperative back pain and disability predictive for outcome. CONCLUSION: Moderate-level evidence supports clinically relevant immediate improvement in leg pain and disability following lumbar discectomy with accompanying improvements in back pain.

Peroneus Tertius Syndrome: A Rare Cause of Anterolateral Ankle and Rearfoot Pain.

There is limited literature describing anterolateral ankle or rearfoot pain associated with the peroneus tertius tendon. The purpose of this study is to define peroneus tertius syndrome, in which the peroneus tertius tendon causes catching or locking over the anterolateral ankle or rearfoot with accompanying pain. We present a retrospective case series involving 4 patients diagnosed with peroneus tertius syndrome, discuss symptoms for clinical diagnosis, review radiographic imaging, and outline a minimally invasive operative technique for resection of the symptomatic tendon. Furthermore, we sought to evaluate postoperative outcomes and satisfaction scores after surgical management. All patients experienced resolution of symptoms by the fourth postoperative week. There was a statistically significant improvement in visual analog scale scores (average ± SD, 7.75 ± 0.96 preoperative to 0.75 ± 1.19 postoperative) (p = .002). Overall patient satisfaction was 100%, with improved functional status and no evidence of recurrent symptoms at final follow-up (average 18.88 ± 8.68 months). Our results demonstrate that excision of a symptomatic peroneus tertius provides resolution of symptoms, facilitates a quick return to activity, and has excellent patient outcomes. We suggest that during the evaluation of anterolateral ankle or rearfoot pain, peroneus tertius syndrome be considered as part of the differential diagnosis.

Comparison of the French and CARDS classifications for lumbar degenerative spondylolisthesis: reliability and validity.

BACKGROUND: The aim of this study was to compare the reliability and validity of the CARDS and French classification systems for lumbar DS. METHODS: Between May 2013 and December 2016, 158 consecutive patients diagnosed with single-level lumbar DS were included in this study, and all underwent lumbar fusion. All patients underwent long-cassette standing anterioposterior and lateral radiographs of the spine preoperatively and postoperatively. The images were graded according to the CARDS and French classification systems by two orthopedic spinal surgeons and two orthopedic spinal fellows, independently. Clinical outcome measures used were the visual analog scale, Oswestry Disability Index, and the 36-Item Short Form Health Survey. Clinical data were collected before surgery and 1 year after surgery. RESULTS: A total of 146 patients were finally included in this study and followed up for at least 1 year. When grading using the CARDS system, the κ values for inter- and intraobserver reliability were 0.837 and 0.869, respectively, representing perfect agreement. The interobserver κ value for the French classification was 0.693 and the intraobserver κ value was 0.743, both representing substantial agreement. CARDS Type D patients have higher preoperative back pain scores and better improvement after surgery compared with non-Type D patients. Mean back and leg pain was worse in French Type 5 patients, while the most significant improvement was also seen in Type 5 patients after surgery. CONCLUSIONS: Both CARDS and French classification systems have acceptable reliability and validity. The CARDS system is easier to utilize and has better reliability. LEVEL OF EVIDENCE: IV.

Hallux valgus correction utilising a modified short scarf osteotomy with a magnesium biodegradable or titanium compression screws - a comparative study of clinical outcomes.

BACKGROUND: Biodegradable implants reduce the likelihood of further surgery for hardware removal and reduce the risks of associated infection and allergy. The purpose of this study is to evaluate the clinical efficacy and determine the comparability of biodegradable magnesium alloy MgYREZr (MAGNEZIX® CS) compression screw fixation compared with standard titanium screw fixation in the surgical treatment of hallux valgus deformity. METHODS: Eleven patients undergoing corrective surgery for hallux valgus utilising biodegradable magnesium screws and a control group of 25 patients undergoing corrective hallux valgus surgery with standard titanium screws were reviewed at a median of 19 months (range 12-30 months). PROM scores (Manchester-Oxford Foot Questionnaire (MOXFQ), Foot and Ankle Outcomes Instrument (FAOI) and the EQ-5D-3 L) were recorded preoperatively and at latest follow-up. RESULTS: The results between the two groups were broadly similar, with the Magnesium and Titanium patients showing similar patterns in the various domains in the MOXFQ, the FAOI and the EQ-5D-3 L. Most patients reported a near full shoe comfort score, and EQ-5D-3 L scores were significantly improved in both patient groups (with most patients reporting a full score). Foot pain and foot function improved irrespective of the scoring systems and patients in both groups demonstrated significantly improved scores following the surgery (p < 0.05). Notably, there were no significant differences when comparing the post-operative scores between the groups for any individual scoring parameter. No impairment to quality of life was recorded. There were no intra or post-operative complications. There were no problems encountered through the use of the bioabsorbable screws. CONCLUSION: Biodegradable magnesium-based compression screws appeared to be safe in this study and are an effective fixation device in the treatment of hallux valgus deformity with clinical outcomes similar to standard titanium screw fixation.

Long-term pain relief at five years after medical, repeat surgical procedures or no management for recurrence of trigeminal neuralgia after microvascular decompression: analysis of a historical cohort.

BACKGROUND: Management strategies for the recurrence of trigeminal neuralgia after microvascular decompression include repeat procedures, medical management or no further therapy. No consensus exists as to which strategy is best for pain relief. The aim of this study was to determine the characteristics of patients with recurrences after microvascular decompression in the cohort, and to compare long-term pain relief between different management strategies. MATERIALS AND METHODS: A historical cohort of patients who underwent microvascular decompression at a neurosurgical institution between 1982-2002, followed up by postal survey at five years, was included. Characteristics of patients who experienced a recurrence were compared to those who were recurrence free, and pain relief was compared between each management strategy. RESULTS: From 169 responders who were included in the study, 28 (16.6%) experienced a recurrence after MVD. No characteristics were significantly different between patients who experienced a recurrence and those who did not. Repeat procedures, including repeat microvascular decompression, partial sensory rhizotomy or radiofrequency thermocoagulation, yielded the highest proportion of pain relief after recurrence (p = 0.031), with 63.6% of patients pain-free at five-years. There was no evidence to suggest that the choice of repeat procedure influenced the likelihood of pain relief after recurrence. No further treatment yielded 57.1% pain-free, whereas medical therapy had the lowest proportion of pain-free patients, at 10.0%. CONCLUSION: A variety of options are available to patients for recurrence of TN after microvascular decompression with repeat procedures yielding the greatest likelihood of long-term pain relief in this historical cohort. The choice of management should consider the mechanism of recurrence, the benefits and risks of each option and the severity of the pain. Regardless of the management strategy selected, careful phenotyping of patients before and after surgery is paramount.

10-year results of the Nesovic procedure combined with adductor release for groin pain in 33 competitive athletes.

The authors present a 10-year review of the postoperative bilateral release of the adductor brevis and gracilis muscles combined with a bilateral abdominal myo-fascio-plasty according to Nesovic for groin pain in competitive athletes. We present the 10 years results of 33 patients operated on between April 2002 and May 2006 diagnosed with a "sports hernia". The injury was treated with a bilateral abdominal procedure according to Nesovic combined with a bilateral adductor release after unsuccessful conservative treatment of at least 2 months. There were 32 male patients between 18 and 43 years and one female patient aged 25 years with a mean age of 28.8 at time of surgery. All procedures were bilateral. Patients were seen in the postoperative clinic and a questionnaire was collected after 2 years and 10 years. Within 16 weeks, 30 patients (90,9 %) returned to the same or a higher level of sports activities. 10 years after surgery 31 patients (93,9%) remained free of pain. 1 patient has minor pain after training (VAS 0-1) and only 1 patient still experiences pain (VAS ≥ 5) after heavy work. 13 patients (39,3%) are still performing sports today, and 19 of 20 patients (95%, 57% of total cohort) were pain free to the end of their sporting careers. The bilateral Nesovic procedure with bilateral adductor release has a high success rate for the competitive athlete with chronic groin pain. It also is a procedure that gave most athletes suffering from a certain type of groin pain a solution till the end of their sporting careers.

Fasciotomy for chronic exertional compartment syndrome of the leg: clinical outcome in a large retrospective cohort.

BACKGROUND: Chronic exertional compartment syndrome (CECS) is an overuse disorder typically affecting an athletic population. CECS is a diagnosis based on history and intracompartmental pressure (ICP) testing. CECS patients can be treated surgically by fasciotomy; however, research on the relationship between ICP and patient symptoms and also between ICP and patient-reported outcome post-fasciotomy is limited. This study aims to (1) assess functional outcome and patient satisfaction post-fasciotomy and (2) identify any potential correlation between ICP and reported levels of pain. METHODS: 138 CECS patients who had ICP measurements and subsequently underwent fasciotomy were identified from our regional service for exercise-induced lower limb extremity pain between January 2000 and March 2017. Clinical outcomes were recorded at the time of ICP testing and in the post-operative follow-up clinic. Pain was reported using a verbal rating scale (VRS) ('low', 'moderate' or 'high') or as a visual analogue score (VAS) 0-10 (0 = least painful, 10 = most painful). Spearman's ranked correlation test was used to calculate correlation between ICP and reported pain. RESULTS: A total of 138 patients were eligible for inclusion in this study (mean age 29.7 ± 9.7 years, 110 M, 28 F) of which 109 patients (VRS n = 61, VAS n = 48) reported pain level at pre- and post-operative stages. Mean pre-operative VAS score was 8.52 ± 0.71, and decreased to 0.77 ± 0.69 post-operatively. An insignificant positive correlation (r = 0.046, two-tailed p = 0.76) was found between VAS pain and ICP. A significant moderate positive correlation (r = 0.497, two-tailed p = 0.01) was found between VRS pain and ICP. CONCLUSION: Fasciotomy significantly reduces pain and increases activity levels in CECS patients. ICP was found to positively correlate with patient-reported pain.

Is Physician Empathy Associated With Differences in Pain and Functional Limitations After a Hand Surgeon Visit?

BACKGROUND: In prior work we demonstrated that patient-rated physician empathy was the strongest driver of patient satisfaction after a visit to an orthopaedic hand surgeon. Data from the primary care setting suggest a positive association between physician empathy and clinical outcomes, including symptoms of the common cold. It is possible that an empathic encounter could make immediate and measureable changes in a patient's mindset, symptoms, and functional limitations. QUESTIONS/PURPOSES: (1) Comparing patients who rated their physicians as perfectly empathic with those who did not, is there a difference in pre- to postvisit change in Patient Reported Outcome Measurement Information System (PROMIS) Upper Extremity Function scores? (2) Do patients who gave their physicians perfectly empathic ratings have a greater decrease in pre- to postvisit change in Pain Intensity, PROMIS Pain Interference, and PROMIS Depression scores? METHODS: Between September 2015 and February 2016, based on the clinic patient flow, 134 new patients were asked to participate in this study. Eight patients were in a rush to leave the surgeon's office, which left us with a final cohort of 126 patients. Directly before and directly after the appointment with their physician, patients were asked to complete three PROMIS Computerized Adaptive Tests (CAT; Upper Extremity Function, Pain Interference, and Depression) as well as an ordinal rating of pain intensity. After the visit, participants were asked to rate their physician using the Consultation And Relational Empathy (CARE) measure. Based on prior experience, we dichotomized the CARE score anticipating a substantial skew: 54 patients (43%) rated their physician perfectly empathic. RESULTS: Between patients who rated physicians as perfectly empathic and those who did not, there was no difference in the pre- to postvisit change in PROMIS Upper Extremity Function CAT score (perfect empathy: 0.84 ± 2.94; less than perfect empathy: -0.23 ± 3.12; mean difference: 0.23; 95% confidence interval [CI], -0.31 to 0.77; p = 0.054). There was a small decrease in Pain Intensity (perfect empathy: -0.96 ± 2.08; less than perfect empathy: -0.33 ± 1.03; mean difference: -0.60; 95% CI, -0.88 to -0.32; p = 0.028). There were no differences in PROMIS Pain Interference score (perfect empathy: -1.33 ± 2.85; less than perfect empathy: -1.37 ± 3.12; mean difference: -1.35; 95% CI, -1.88 to -0.83; p = 0.959) or PROMIS Depression scores (perfect empathy: -1.51 ± 4.02; less than perfect empathy : -1.21 ± 3.83; mean difference: -1.34; 95% CI, -2.03 to -0.65; p = 0.663). CONCLUSIONS: A single visit with a surgeon rated perfectly empathic is not associated with change in upper extremity-specific limitations or coping mechanisms or a noticeable change in pain scores during the visit, as these differences were below the minimum clinically important difference. Future research should address the influence of empathy on patient-reported outcomes and physician empathy over time in contrast to a single office visit. LEVEL OF EVIDENCE: Level II, prognostic study.

Surgical management of lateral epicondylitis combined with ligament insufficiency.

BACKGROUND: Lateral collateral ligament (LCL) insufficiency may occur in patients with chronic lateral epicondylitis (LE). We report on 14 consecutive patients with chronic LE and LCL insufficiency. METHODS: We performed a retrospective review of 14 patients with LE and LCL insufficiency diagnosed between 2006 and 2015. The patients had undergone débridement for LE and ligament reconstruction for LCL insufficiency. The study included 9 men and 5 women with an average age of 53 years (range, 41-69 years). The mean follow-up period was 36 months (range, 24-97 months). We analyzed the pain visual analog scale score; Mayo Elbow Performance Score; Disabilities of the Arm, Shoulder and Hand score; range of motion; and posterolateral rotatory drawer test. We compared histories of steroid injection, trauma, and surgery. RESULTS: The pain visual analog scale score, Mayo Elbow Performance Score, and Disabilities of the Arm, Shoulder and Hand score were significantly improved postoperatively and improved in all patients. Three patients had mild instability on the stress test at final follow-up. All patients had a history of steroid injection, 2 had a history of trauma, and 3 had a history of surgery. The number of steroid injections and the number of cases receiving steroid injections more than 3 times were significantly higher in patients with LCL insufficiency. CONCLUSIONS: Assessment of stability is important in patients with chronic LE and risk factors such as multiple steroid injections. Simultaneous surgical treatment including open débridement and ligament reconstruction provides satisfactory pain relief and functional improvement in patients with LE and LCL insufficiency.

Clinical outcomes of anconeus interposition arthroplasty after radial head resection in native and prosthetic radial heads.

BACKGROUND: Radiocapitellar pathology after traumatic injury to the elbow can be challenging to treat. The anconeus interposition arthroplasty has been proposed to treat radiocapitellar or proximal radioulnar joint dysfunction and pain, or both. This study evaluated whether radial head excision (native or prosthetic), followed by an anconeus interposition arthroplasty, relieves pain and improves subjective and objective elbow function in patients with post-traumatic radiocapitellar pathology. METHODS: A retrospective comparative case series was performed of 50 consecutive patients who underwent a native radial head excision or radial head implant excision, followed by an anconeus interposition arthroplasty. Clinical outcome scores, range of motion, and proximal radius migration were evaluated in patients with at least 2 years of follow-up. RESULTS: Included were 23 patients (11 native and 12 prosthetic radial heads) with a mean age of 41 years. Average follow-up was 38 months. Overall, significant improvement was obtained in the Disabilities of the Arm, Shoulder and Hand and visual analog scale scores. Range of motion significantly improved from preoperatively to postoperatively. Patients with a native radial head excision scored better on the Single Assessment Numeric Evaluation (76.8 vs. 56.3, P = .037) and obtained significantly more flexion postoperatively (141° vs. 123°, P = .016). Mild wrist pain developed in 3 patients, but no further intervention was required. The overall complication rate was 13%, and 5 patients required reoperation. CONCLUSIONS: Anconeus interposition arthroplasty performed after radial head resection in native and prosthetic groups is a viable adjunct in the operative treatment of patients with post-traumatic radiocapitellar pathology. However, whether anconeus interposition arthroplasty alone produced the favorable clinical results of this study was difficult to determine.

Reversed Palmaris Longus Muscle Causing Volar Forearm Pain and Ulnar Nerve Paresthesia.

A case of volar forearm pain associated with ulnar nerve paresthesia caused by a reversed palmaris longus muscle is described. The patient, an otherwise healthy 46-year-old male laborer, presented after a previous unsuccessful forearm fasciotomy for complaints of exercise exacerbated pain affecting the volar forearm associated with paresthesia in the ulnar nerve distribution. A second decompressive fasciotomy was performed revealing an anomalous "reversed" palmaris longus, with the muscle belly located distally. Resection of the anomalous muscle was performed with full relief of pain and sensory symptoms.

Arthroscopic surgical treatment of medial epicondylitis.

BACKGROUND: The study purpose was to evaluate the outcomes of patients who received arthroscopic surgical treatment for medial epicondylitis refractory to conservative treatment. METHODS: This was a retrospective study of 7 patients who underwent arthroscopic surgical débridement of the common flexor tendon for treatment of medial epicondylitis refractory to conservative treatment. The patients were assessed using the Disabilities of the Arm, Shoulder and Hand score; visual analog scale for pain; and Short Form 36 Health Survey. The mean age at the time of surgery was 50 years (range, 36-67 years). The mean duration of symptoms before surgery was approximately 2 years (range, 8 months to 4 years). The mean follow-up duration was 17 months (range, 6-48 months). RESULTS: The average postoperative scores were 17 points on the Disabilities of the Arm, Shoulder and Hand outcome measure; 2 points on the visual analog scale at rest for 6 subjects (86%) with slight pain and 1 (14%) with moderate pain; and 78 on the Short Form 36 Health Survey. No significant complications were observed when the procedure was performed via arthroscopy. CONCLUSION: Arthroscopic surgical treatment for medial epicondylitis of the elbow exhibits good outcomes and is safe and effective.

Resection of Small Avulsion Fractures of the Anterior Process of the Calcaneus for Refractory Complaints.

Minor injuries of the anterior process of the calcaneus occur frequently and most heal uneventfully. The present series reports on 6 patients with persistent complaints after anterior process avulsion fractures. The avulsed fragments of the anterior process at the calcaneocuboid joint were surgically excised in all, which resolved the complaints completely in 4 patients and reduced the complaints significantly in 2. If conservative measures fail and the complaints are refractory, debridement of the anterior process avulsion fractures at the calcaneocuboid joint could be a viable option.

Eaton and Littler Ligament Reconstruction for the Painful first Carpometacarpal Joint : Patient satisfaction.

The ligamentous reconstruction according to Eaton and Littler (7) was designed to restore the stability of the carpometacarpal joint of the thumb. We evaluated the patients' satisfaction after an Eaton and Littler-procedure as well as possible risk factors in the development of thumb basal joint instability. A retrospective chart review and clinical assessment or telephone survey are executed in 33 patients, with a mean follow-up of 7 years. Only 45% of the patients were satisfied. Within the group of clinical assessed patients, there were significant differences in thumb function comparing operated with not operated side. Overall joint hypermobility can be a contributing factor for this thumb basal joint instability, but has no effect on the outcome after an Eaton-Littler procedure.

Trapeziumectomy And Mini Tightrope Stabilization Of The First Metacarpal For Thumb Carpometacarpal Osteoarthritis : A Prospective Case Series.

Our purpose was to investigate the short-term results of trapeziumectomy and stabilization of the first metacarpal by using the TightRope© device, at a maximum follow-up of 1 year post-op. This is a novel method in treating first carpometacarpal joint osteoarthritis and an alternative to the variety of other methods that have been previously reported. We recruited 21 patients and assessed them at regular intervals, comparing pre-operative and postoperative variables. We recorded all complications during the study period. There was a statistically significant improvement in pain, hand grip and tip pinch power and functional outcome scores. Patients were very satisfied at 12 months after surgery. No significant change in thumb opposition was noted. There was subsidence of the first metacarpal at 1 year after surgery. Despite the existence of a significant number of alternative procedures, we feel that the procedure described in this paper has promising short-term results and is safe.

Total knee replacement in a resource constrained environment: A preliminary report.

INTRODUCTION: Total knee replacement surgery is relatively new in Nigeria and available in few centres only. It has been evolving at a slow pace because of the lack of facilities, structures and adequate surgical expertise alongside patient ignorance and poverty. OBJECTIVE: The aim of this article is to review the cases done in a resource constrained institution in Nigeria and report the short term outcomes. METHODOLOGY: All the patients that were booked for Total knee replacement, using same prosthesis over a 40 month period, were recruited into the study. Using a prepared data tool, information on personal biological information, clinical presentation, peri-operative management, and outcome of management were obtained after an informed verbal consent. All the patients were further followed up for at least one year. RESULTS: 45 knees were replaced in 38 patients. The age range of the patients was 41-85 years with a mean age of 62.6. The male to female ratio was 1: 4.4. The indications for surgery were a combination of pain and deformity. All the patients came with varying forms and degrees of angular deformities. Eight knees had bone defects that required bone grafting while 5 knees had tibia extension rods. The commonest complication, which was recorded, was drop foot (8.9%). Knee society pain scores in the patients improved from the average of 21.35 to 83. CONCLUSION: Despite the challenges inherent in health care in developing countries, with proper institutional planning and team work, the short term outcome of arthroplasty in our resource constrained environment is good.

CT-guided cement sacroplasty (CSP) as pain therapy in non-dislocated insufficiency fractures.

INTRODUCTION: In elderly patients with reduced bone quality, insufficiency fractures of the sacrum are relatively common and are typically associated with severe disabling pain. The objective of the present study was to examine the feasibility of cement augmentation by CSP, to determine post-interventional leakages and other complications, and to present the outcome of pain over the course of 18 months. MATERIALS AND METHODS: In 23 patients (20 women and 3 men) with an average age of 81.3 (71-92) years, a total of 41 sacral fractures were detected by MRI, 5 of them unilateral and 18 bilateral. Conservative treatment initially performed over a period of 3 weeks did not bring any satisfactory reduction in the severe disabling pain. The indication for intervention was established after an interdisciplinary case conference. The intervention was performed under intubation anaesthesia. Single-shot antibiotic prophylaxis was given routinely immediately prior to the intervention. Under sterile conditions, a Jamshidi needle was then advanced into the respective fracture zone in the sacrum from dorsal to ventral (short axis) or from lateral to medial transiliac (transiliac axis). After removing the inner needle, a flexible osteotome was inserted through the positioned hollow needle and used to extend the spongious space in the fracture zone and thus prepare a cavity for the cement filling. High-viscosity PMMA cement was then inserted discontinuously with the aid of a pressure gauge under low-dose CT control. Cement leakages were determined in the CT image on the day after the intervention, all cement outside of the cortical boundary being rated as a leakage. Pain was documented on a visual analogue scale (VAS) on the day before the intervention, on the second day, and 6, 12, and 18 months after the intervention. Additionally occurring complications were recorded, and the patients were asked to rate their satisfaction after 6 and 18 months. RESULTS: CSP was technically feasible in all patients. In the control CT scan, sufficient cement distribution and interlocking with vital bone were found along the course of the fracture in the sacrum. An average of 6.0 ± 0.83 ml of cement was inserted per fracture. Leakage was found in 5 of 41 (12.2%) of the fractures treated, although none were symptomatic. The mean pain score on the VAS was 8.8 ± 0.59 before the intervention, a significant pain reduction (p < 0.0005) was seen on the second post-operative day, with an average value of 2.1 ± 0.36, and this was stable at 2.2 ± 0.28 after 6, 2.3 ± 0.31 after 12, and 2.2 ± 0.41 after 18 months. Now that they no longer experienced disabling pain, all of the patients were fully remobilised and discharged back home. A high level of patient satisfaction was found after 6 and 18 months. CONCLUSION: As a minimally invasive procedure, CSP is an effective treatment method for rapid, significant, and sustained pain reduction.

Treatment of hand enchondroma with injectable calcium phosphate cement: a series of eight cases.

The gold standard treatment for enchondroma in the hand is curettage and filling of the defect. The goal of this study was to evaluate the results when injectable calcium phosphate cement is used to fill the bone defect. Eight patients having a mean age of 44 years were operated through a minimally invasive skin incision. After a small bone window was made, curettage of the lesion was performed and verified by intraosseous endoscopy. The defect was filled with injectable calcium phosphate cement (JectOS/AREX®BONE, Kasios, L'Union France). The mean pain score (out of 10) decreased from 4.1 preoperatively to 1.6 postoperatively. The mean QuickDASH (out of 100) improved from 37.66 to 24.14. At the last follow-up (mean of 16 months), the range of motion in the operated hand had reached 89.3% of the contralateral hand. Based on radiographs, a mean of 69.3% calcium phosphate cement remained in the bone. There were two cases of extraosseous cement leakage, one of which required revision and resulted in a poor outcome. Overall, these results show that curettage of a hand enchondroma followed by filling of the defect with injectable calcium phosphate cement is a simple, reliable technique with no donor site morbidity, as long as cement does not leak out.
