  • Article: An Evidence-Based Review of a Single Surgeon's Experience With Endoscopic Carpal Tunnel Release.
    [show abstract] [hide abstract]
    ABSTRACT: Although introduced more than 20 years ago, endoscopic carpal tunnel release (ECTR) continues to generate debate and controversy among surgeons. This review examines a single surgeon's technique for ECTR over the past 13 years to better understand the effects of a surgeon's experience on outcomes. A retrospective review was performed on a case series of 129 patients ages 25 to 89 years old who underwent an ECTR at Duke University. Ninety-six percent of patients reported improvement in nerve symptoms. There were no nerve complications in the series. The billed cost of ECTR at Duke University was 9% less than standard open release and the average return to work by report by patients was 3 weeks. Previous recommendations against ECTR have focused on increased complication rates and cost, with no reported differences in long-term clinical outcomes. The results demonstrate increased success and lower complication rates for this series of patients. This may indicate a significant correlation between a surgeon's expertise and outcomes for ECTR.

  • Article: Free Vascularized Fibular Grafting Preserves Athletic Activity Level in Patients With Osteonecrosis.
    [show abstract] [hide abstract]
    ABSTRACT: Athletic patients with osteonecrosis of the femoral head have few desirable therapeutic options that preserve athletic ability. Because these patients are usually young and healthy, any procedure that avoids total hip arthroplasty would be most desirable. This study prospectively evaluated 15 patients (19 hips) who presented with an average age of 28.5 (range, 12 to 46) years and stages 2 (6/19), 3 (2/19), 4 (9/19), and 5 (2/19) of osteonecrosis of the femoral head. All patients were treated with free vascularized fibular autografting (FVFG) to the femoral head. Postoperative evaluations of pain symptoms and functional activity showed improvements in all patients. The average follow-up time was 8 years. Harris hip scores significantly increased from an average preoperative score of 75.3 to an average postoperative score of 94.8. Seventy-five percent of patients were able to return to their sport after recovery and all patients reported being satisfied with the procedure and would repeat their decision to have surgery. Three patients' hips were converted to arthroplasty at 3, 11, and 17 years post-FVFG. The results demonstrate that FVFG is a successful therapeutic treatment in athletes with osteonecrosis of the femoral head. It reduces pain, increases activity, and allows most patients to return to their sport, an achievement often not possible with other treatment options.

  • Article: Recurrent compartment syndrome: 2 cases and a review of the literature.
    Trevor R Gaskill, Robert Zura, J Mack Aldridge
    [show abstract] [hide abstract]
    ABSTRACT: Compartment syndrome is a potentially devastating entity, and timely recognition is critical for appropriate management. Diagnosis is classically a clinical one and based largely on serial examinations. When clinical examinations are compromised, compartment pressure monitoring may be useful. These diagnostic measures, however, assume recognition of "at-risk" injuries or clinical scenarios. Rarely discussed is whether an open fasciotomy provides any degree of protection from redeveloping compartment syndrome. To this end, we present 2 cases of recurrent compartment syndrome after previous fasciotomy. These reports illustrate a previously unreported at-risk population and demonstrate that compartment syndrome can recur in a previously released compartment. Therefore, prior fasciotomy should not be considered protective against acute compartment syndrome. These patients should be evaluated and managed no differently from patients with primary compartment syndrome.

  • Article: Traumatic valgus instability of the elbow: pathoanatomy and results of direct repair. Surgical technique.
    [show abstract] [hide abstract]
    ABSTRACT: The medial collateral ligament provides valgus stability to the elbow. The purpose of the present study was to describe the pathoanatomy of acute traumatic medial collateral ligament ruptures and to report the rationale and results of direct repair. Between 1996 and 2006, eleven athletes presented with acute rupture of the medial collateral ligament of the elbow and no history of dislocation. Three patients had received steroid injections for the treatment of medial epicondylitis, but none had a history of medial elbow insufficiency. All patients demonstrated gross valgus instability on clinical examination and medial joint space widening on valgus stress radiographs. Complete avulsion of the medial collateral ligament from its humeral origin was documented with magnetic resonance imaging in all patients. Operative findings uniformly demonstrated avulsion of the flexor-pronator muscles with distal retraction. The underlying medial collateral ligament was avulsed in a sleeve-like fashion from the denuded medial epicondyle. The ligament was directly reattached to its footprint. The avulsed flexor-pronator tendon was repaired to the residual tendon with use of interrupted figure-of-eight nonabsorbable sutures. All patients were followed for a minimum of sixteen months with serial clinical examinations, radiographs, and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Full active range of motion was achieved in ten patients; the remaining patient had a 20 degrees flexion contracture. Three patients had acute ulnar nerve palsies at the time of the injury, and all three recovered complete motor and sensory function by six months after the injury. Nine of the eleven patients returned to competitive college athletics between four and six months. The mean DASH score at the time of the most recent follow-up was 6. Direct repair of an acute traumatic medial collateral ligament avulsion of the elbow reliably restores valgus stability, even in throwing athletes.

  • Article: Free vascularized fibular transfer for femoral head osteonecrosis: donor and graft site morbidity.
    [show abstract] [hide abstract]
    ABSTRACT: Autogenous vascularized fibular transfer is used effectively for a variety of complex reconstructive procedures. Published series demonstrating the morbidity associated with its harvest have, understandably, been relatively small, and graft site (hip) complications have not been reported. This report describes both the donor and the graft site morbidity associated with use of vascularized fibular transfer to treat osteonecrosis of the femoral head. Between 1990 and 2006, 1270 free vascularized fibular grafts were used to treat osteonecrosis of the femoral head in 946 consecutive patients. All procedures and follow-up examinations were performed by one of two surgeons. Subjective and objective findings were recorded on standardized examination sheets at routine postoperative intervals. Data were analyzed to determine the morbidity associated with donor and graft sites. There were 215 complications (a 16.9% rate) at the time of follow-up, at an average of 8.3 years, after the 1270 procedures. Of these complications, 146 (11.5%) and sixty-nine (5.4%) were referable to the donor and graft sites, respectively. A major complication requiring an additional surgical procedure or chronic pain management occurred after fifty-four (4.3%) of the 1270 procedures. A measurable but acceptable morbidity risk is associated with vascularized fibular transfer for the treatment of osteonecrosis of the hip. Major complications are not frequent, and many minor complications are transient and improve over time. Risks can be minimized when specific technical principles are followed.

  • Article: Free Vascularized Fibular Grafting for treatment of osteonecrosis of the femoral head secondary to hip dislocation.
    [show abstract] [hide abstract]
    ABSTRACT: Traumatic dislocation of the hip results in osteonecrosis of the femoral head (ONFH) or avascular necrosis (AVN) in approximately 40% of patients. This high-energy event causes an ischemic insult to the femoral head that may lead to ONFH. Here, we investigate use of Free-Vascularized Fibular Grafting (FVFG) in patients with ONFH after traumatic hip dislocation. Thirty-five patients with FVFG for this indication were reviewed (average follow-up 3.3 years, range 1-21). We reviewed patient injury statistics, demographics, preoperative radiographs, pre- and postoperative Harris Hip scores, complications, and rate of conversion to total hip arthroplasty (THA). The majority (81%) of our patients were young males (22 years) with ONFH diagnosed an average of 2 years after injury. The average preoperative Harris Hip score was 64.9 which improved by over 10 points to 76.1 at 1-year follow-up. Seven of 35 patients required conversion to THA at an average of 45 (13-86) months postoperation. After a maximum follow up of 21 years, the remainder of the patients retained their native hips and Harris Hip scores tended to show improved hip function.

  • Article: Vascularized fibular grafting for osteonecrosis of the femoral head with unusual indications.
    J Mack Aldridge, James R Urbaniak
    [show abstract] [hide abstract]
    ABSTRACT: We retrospectively reviewed the charts of 154 patients of various subgroups treated with the free vascularized fibular graft procedure for osteonecrosis of the femoral head (ONFH), evaluating pre- and postoperative Harris hip scores, hip range of motion, radiographs, and number of conversions to total hip arthroplasty (THA). Patients were followed a minimum of 1 year (mean, 6.8 years, range, 1 to 19 years). Athletes and patients with pyarthrosis-related osteonecrosis had high Harris hip scores at final review with scores of 94 and 97, respectively. Patients with ONFH after a slipped capital femoral epiphysis or following pregnancy had a low conversion rate to THA at 6% and 8%, respectively. Twenty-five percent of patients with transplant-related osteonecrosis of the femoral head were converted to THA at an average of 2.7 years. However, with select subsets of patients (athletes, pregnancy, organ transplant, femoral neck non-union, slipped capital femoral epiphysis, infection) the FVFG can result in a high rate of success.

  • Article: Acute distal radioulnar joint instability.
    Grant E Garrigues, Vani Sabesan, J Mack Aldridge
    [show abstract] [hide abstract]
    ABSTRACT: The distal radioulnar joint (DRUJ) is critical for pronosupination of the forearm and for upper extremity function in general. Because of its critical role in tool handling, some authors place the human DRUJ on par with the opposable thumb in the evolution of man. This seemingly simple cylindrical joint is stabilized by a complex network of soft tissue constraints, primarily components of the triangular fibrocartilage complex. Chief among these are the dorsal and palmar radioulnar ligaments. Any injury that disrupts these stabilizers, their balanced tension, or the bony congruity of the joint will have a major deleterious effect on hand function. Although they can occur in isolation, injuries causing acute DRUJ instability generally are associated with other trauma to the forearm-wrist complex. When managing these associated injuries, it is paramount to have a high index of suspicion for associated acute DRUJ instability. If the DRUJ is evaluated and stabilized in the acute setting, the more difficult clinical problem of chronic DRUJ instability can be avoided.

  • Article: Malunions and nonunions of the forearm.
    Marc J Richard, David S Ruch, J Mack Aldridge
    [show abstract] [hide abstract]
    ABSTRACT: Modern techniques allow for high rates of union in the treatment of diaphyseal forearm fractures. In the case of nonunion, addressing the biology and stability of the fracture will similarly yield high union rates, but slightly decreased functional outcomes. Malunion of forearm fractures typically results in loss of range of motion and grip strength. Restoration of the anatomical relationships of the forearm yields functional results. Understanding and recreating the anatomy of the forearm is the key to obtaining good functional outcomes.

  • Article: Hip incision planning for free vascularized fibular grafting of the proximal femur: a handy tip.
    [show abstract] [hide abstract]
    ABSTRACT: Free vascularized fibula graft surgery has been shown to be successful in the treatment of osteonecrosis of the femoral head. Refinements in the surgical technique have greatly decreased patient morbidity and overall surgical time. Careful placement of the hip incision is one such refinement. Specific bony landmarks to map out the location of the incision and a simple technique for incision placement are described. An accurately placed 10- to 15-cm incision will allow access to both the proximal femur and the ascending branch of the lateral femoral circumflex artery and veins.

  • Article: Median nerve entrapment in a pediatric both-bone forearm fracture: recognition and management in the acute setting.
    Jason M Hurst, J Mack Aldridge
    [show abstract] [hide abstract]
    ABSTRACT: Entrapment of the median nerve in pediatric both-bone forearm fractures is a rare occurrence, but there are multiple reports of such cases in the literature. This case report discusses the recognition and management of median nerve entrapment in a 13-year-old female who presented acutely with a both-bone forearm fracture and a reproducible neurologic deficit in the median nerve distribution. She was treated with acute open reduction and internal plate fixation and median nerve exploration. Her median nerve function was near normal 14 weeks after surgery. This report stresses the importance of a complete neurologic examination in all forearm fractures and demonstrates the recovery potential of a median nerve damaged by bony entrapment.

    Article: Free vascularized fibular grafting for the treatment of postcollapse osteonecrosis of the femoral head. Surgical technique.
    [show abstract] [hide abstract]
    ABSTRACT: Osteonecrosis of the femoral head, a disease primarily affecting young adults, is often associated with collapse of the articular surface and subsequent arthrosis. Free vascularized fibular grafting has been reported to be successful for patients with early stages of osteonecrosis, but little is known about its efficacy after the femoral head has collapsed. We retrospectively reviewed the results in a consecutive series of 188 patients (224 hips) who had undergone free vascularized fibular grafting, between 1989 and 1999, for the treatment of osteonecrosis of the hip that had led to collapse of the femoral-head but not to arthrosis. The average duration of follow-up was 4.3 years (range, two to twelve years). We defined conversion to total hip arthroplasty as the failure end point, and we analyzed the contribution, to failure, of the size of the lesion, amount of preoperative collapse of the femoral head, etiology of the osteonecrosis, age of the patient, and bilaterality of the lesion. We used the Harris hip score to evaluate clinical status preoperatively and at the time of the most recent follow-up. The overall rate of survival was 67.4% for the hips followed for a minimum of two years and 64.5% for those followed for a minimum of five years. The mean preoperative Harris hip score was 54.5 points, and it increased to 81 points for the patients in whom the surgery succeeded; 63% of the patients in that group had a good or excellent result. There was a significant relationship between the outcome of the grafting procedure and the etiology of the osteonecrosis (p = 0.017). Patients in whom the osteonecrosis was idiopathic, associated with alcohol abuse, or posttraumatic fared worse than did those with other causes, including steroid use. Survival of the joint was not significantly related to the size of the femoral head lesion, but there was an increased relative risk of conversion to total hip arthroplasty with increasing lesion size and amount of collapse. Neither patient age nor bilaterality significantly affected outcome. Patients with postcollapse, predegenerative osteonecrosis of the femoral head appear to benefit from free vascularized fibular grafting, with good overall survival of the joint and significant improvement in the Harris hip score. The results of this femoral head-preserving procedure in patients with postcollapse osteonecrosis are superior to those of core decompression and nonoperative treatment, as reported in the literature. Patients with larger lesions and certain diagnoses, such as idiopathic and alcohol-related osteonecrosis, have worse outcomes.

  • Article: Combined pectoralis major and latissimus dorsi tendon transfer for massive rotator cuff deficiency.
    J Mack Aldridge, Todd S Atkinson, William J Mallon
    [show abstract] [hide abstract]
    ABSTRACT: This report is a retrospective review of 11 consecutive patients treated with a combined transfer of the latissimus dorsi and pectoralis major tendons for massive rotator cuff deficiency. Each patient's chief complaint was diminished shoulder function and motion with little or no accompanying pain. The primary operative objective was to increase active shoulder motion. All 11 patients were followed up for at least 2 years (range, 24 to 42 months). The mean active elevation improved from 42 degrees preoperatively to 86 degrees postoperatively. The mean active external rotation improved from 0 degrees to 13 degrees. On the basis of the Medical Research Council scale, the mean abduction strength improved from 2.3 to 3.1 and the mean external rotation strength improved from 2.1 to 2.7. Overall, 4 patients made no improvement, 2 improved slightly, and 5 improved significantly. We conclude that a combined transfer of the latissimus dorsi and pectoralis major is a reasonable and safe procedure that may restore active elevation and external rotation in some patients' shoulders with a massive rotator cuff deficiency that have not responded favorably to traditional nonoperative and operative techniques. However, it is difficult to conclude, based on our experience, for which patients this surgery can be predictably successful.

  • Article: Comparison of perioperative complications in patients with and without rheumatoid arthritis who receive total elbow replacement.
    [show abstract] [hide abstract]
    ABSTRACT: Total elbow replacement is a well-recognized surgical treatment for patients with advanced rheumatoid arthritis (RA) of the elbow. At present, there is minimal literature outlining the perioperative complications associated with total elbow replacement. We endeavored to identify complication rates and hospital disposition differences between patients with and without RA who received a total elbow replacement. Data from the Nationwide Inpatient Sample was used to capture 3,617 patients who received a total elbow arthroplasty between 1988-2005. Of these, 888 had a primary diagnosis of RA and were compared against patients without RA. Analyses addressed perioperative complications and hospital disposition factors, such as charges and length of stay. Overall complication rates were very low with only 2 variables, respiratory complications (P = .01) and renal failure (P = .04) demonstrating significantly worse outcomes in patients without RA (P = .01). Patients without RA had also had longer lengths of stay (P < 0.01). There were 9 reported perioperative deaths. The findings suggest that the perioperative complications of a total elbow replacement for all patients studied are few and that outcomes in patients with RA are nearly equivalent to those in patients without RA.
