The prevalence of symptomatic arthritis is about nine times lower than the rates associated with those of the knee or hip.1 Though less common than knee and hip arthritis, the US estimates greater than 50,000 new cases are reported each year.2 The most common etiology of ankle arthritis is post-traumatic pathology.

Study Design: A retrospective analysis of two interventional case series. Setting: Department of Orthopaedic Surgery, Kagawa University, Japan. Methods: Subjects comprised 34 patients who underwent SC and 49 patients who underwent LP. SC was performed by high-speed drilling to remove vertebral bodies. Autologous strut bone grafting was used. LP was performed as an expansive open-door LP. The level of decompression was from C3 to C7. Clinical evaluations included recovery rate (RR), frequency of C5 root palsy after surgery, re-operation and axial pain. Radiographic assessments included sagittal cervical alignment and bone union. Results: Comparisons between the two groups showed no significant differences in age at surgery, preoperative factors, RR and frequency of C5 palsy. Progression of kyphotic changes, operation time and volumes of blood loss and blood transfusion were significantly greater in the SC (two- or three- level) group. Six patients in the SC group required additional surgery because of pseudoarthrosis, and four patients underwent re-operation because of adjacent level disc degeneration.

    Procedure Coding in ICD-9-CM and ICD- 10-PCS

    Procedure Coding in ICD-9-CM and ICD- 10-PCS ICD-9-CM Volume 3 Procedures are classified in volume 3 of ICD-9-CM, and this section includes both an Alphabetic Index and a Tabular List. This volume follows the same format, organization and conventions as the classification of diseases in volumes 1 and 2. ICD-10-PCS ICD-10-PCS will replace volume 3 of ICD-9-CM. Unlike ICD-10-CM for diagnoses, which is similar in structure and format as the ICD-9-CM volumes 1 and 2, ICD-10-PCS is a completely different system. ICD-10-PCS has a multiaxial seven-character alphanumeric code structure providing unique codes for procedures. The table below gives a brief side-by-side comparison of ICD-9-CM and ICD-10-PCS. ICD-9-CM Volume3 ICD-10-PCS Follows ICD structure (designed for diagnosis Designed and developed to meet healthcare coding) needs for a procedure code system Codes available as a fixed or finite set in list form Codes constructed from flexible code components (values) using tables Codes are numeric Codes are alphanumeric Codes are 3-4 digits long All codes are seven characters long ICD-9-CM and ICD-10-PCS are used to code only hospital inpatient procedures. Hospital outpatient departments, other ambulatory facilities, and physician practices are required to use CPT and HCPCS to report procedures.

    Ankle and Pantalar Arthrodesis

    ANKLE AND PANTALAR ARTHRODESIS George E. Quill, Jr., M.D. In: Foot and Ankle Disorders Edited by Mark S. Myerson, M.D. Since reports in the late 19th Century, arthrodesis has been a successful accepted treatment method for painful disorders of the ankle, subtalar, and transverse tarsal joints. While the title of this chapter involves arthrodesis - the intentional fusion of a joint - as a form of reconstruction, this chapter will address not only surgical technique, but nonoperative methods of care as well. We will address the pathophysiology leading to ankle and hindfoot disability, succinctly review the existing literature on the topic of hindfoot and ankle arthrodesis, highlight the pathomechanics involved, and spend considerable time on establishing the diagnosis, indications, and preoperative planning when surgery is indicated. We also will discuss the rehabilitation of the postoperative patient, as well as the management of complications that may arise after ankle and pantalar arthrodesis. There are more than thirty different viable techniques that have been described in order to achieve successful ankle and hindfoot arthrodesis. It is not the purpose of this chapter to serve as compendium of all the techniques ever described. The author will, rather, attempt to distill into a useful amount of clinically applicable material this vast body of information that the literature and clinical experience provide. Ankle arthrodesis is defined as surgical fusion of the tibia to the talus. Surgical fusion of the ankle (tibiotalar) and subtalar (talocalcaneal) joints at the same operative sitting is termed tibiotalocalcaneal arthrodesis. Fusion of the talus to all the bones articulating with it (distal tibia, calcaneus, navicular, and cuboid) is termed pantalar arthrodesis.
  • Ankle Fusion Protocol

    Ankle Fusion Protocol

    Phone: 574.247.9441 ● Fax: 574.247.9442 ● www.sbortho.com ANKLE FUSION PROTOCOL This is the fusion of the tibia and the talus for ankle joint arthritis. Your ankle will lose the majority of its up and down motion, but typically retain some side to side motion. Occasionally the subtalar joint (between the talus and calcaneus) also needs to be fused, which further stiffens the ankle. Bone graft (typically allograft/cadaver bone or Augment, a synthetic graft) is used, and screws, staples, plates, and/or a metal rod are inserted to hold the bones together as they heal. Below is a general outline for these fusion procedures. MD recommendations and radiographic evidence of healing can always affect the timeline. **This is a guideline for recovery, and specific changes may be indicated on an individual basis** Preoperative Physical Therapy Pre surgical Gait Training, Balance Training, Crutch Training and Knee Scooter Training Phase I- Protection (Weeks 0 to 6) GOALS: - Cast or boot for 6 weeks - Elevation, ice, and medication to control pain and swelling - Non-weight bearing x 6 weeks - Hip and knee AROM, hip strengthening - Core and upper extremity strengthening WEEK 0-2: Nonweightbearing in splint - elevate the leg above the heart to minimize swelling 23 hours/day - ice behind the knee 30 min on/30 min off (Vascutherm or ice bag) - minimize activity and focus on rest 1ST POSTOP (5-7 DAYS): Dressing changed, cast applied - continue strict elevation, ice, NWB WEEKS 2-3: Sutures removed, cast changed WEEKS 4-5: Return for another cast change

In 2013, they reported a review of 6 used for initial treatment of this condition or subsequent studies, which reported a total of 42 procedures of fi rst MPJ treatment, after another surgical procedure has failed. A arthrodesis with autogenous graft as a salvage procedure for failed arthroplasty may result in an excessively shortened a failed Keller arthroplasty. Out of the 42 cases, there were fi rst metatarsal or an overly resected proximal phalanx, 2 reported nonunions for a nonunion rate of 4.8%, which which may necessitate the use of an interpositional bone- is signifi cantly less than the rate reported by Myerson.
